    [0001] The invention comprises a method for producing a plastic vehicle connection part, and its use.
    [0002] As part of increasingly stringent requirements regarding carbon dioxide emissions from motor vehicles, there are also strong efforts to reduce a vehicle's weight and thus its fuel consumption. Constant innovations in the plastics sector make it possible to replace large metal parts of the car body with correspondingly lighter elements made from polymeric materials. In particular, parts of or even the entire window region can be replaced by elements made of polymeric materials. In many cases, along with significantly less weight, these exhibit hardness, stability, and toughness comparable to those of a steel car body window. Also, due to the weight reduction, the vehicle's center of gravity is moved lower, which has a positive effect on handling. Furthermore, compared to metals, polymeric materials can be produced, processed, and formed at significantly lower temperatures. This reduces energy demand and costs during the production of materials.
    [0003] Molded parts made of polymeric materials can be produced in virtually any shape and geometry desired. Special high-performance plastics, such as aramid or kevlar, for example, have very high strength and stability.
    [0004] Many pieces of material made of plastics must satisfy various needs and functions. In this regard, important parameters are stability, fracture behavior, scratch resistance, impact strength, or notched impact strength. In addition to technical considerations such as weight and strength of individual components, shape, geometry, and appearance also play an increasingly important role. Especially in the automobile industry, together with the mechanical properties, design and aesthetic features are also of great significance.
    [0005] In order to combine various characteristics in polymeric materials, they are composed of basic materials of different shapes and different natures. Established methods for producing these materials include two-component or multi-component injection molding methods. Thus, it is possible to combine characteristics with each other, such as weather resistance, surface gloss, and fracture resistance or torsional stability. Also, the relative content of very expensive materials can be reduced.
    [0006] DE 197 22 551 A1 describes a method for producing plastic parts in the two-component injection molding process, in which one of the layers is made of a stably colored plastic.
    [0007] EP 1 743 756 A1 describes a method for producing a component employing an injection molding process, in which, in a first step, a thermoplastic plastic is injected between two sheets. In a second step, the first molded part thus produced is bonded to a second molded part by re-injection of the first molded part with a second thermoplastic plastic. The production of such a component is relatively expensive.
    [0008] EP 1 190 831 A1 describes a method for producing a vehicle glazing made of a plastic in an injection molding process. An A, B, C or D column ornament is sprayed onto the vehicle window glass as a second component. The column ornament can be decoratively colored.

    [0012] An established method for producing optical effects is the film insert molding (FIM) method. In this method, a suitable film is stretched into the injection mold and re-injected with a suitable plastic. In this way, the surface and geometry properties of polymeric materials can be selectively and versatilely affected and modified. Temperature stable films are an important prerequisite for using the film insert molding method. In addition, prints located on the film must also be temperature resistant enough to survive back-injection with a liquid polymer such as polycarbonate. Since the film is positioned on the outside of the workpiece, it is not protected from external mechanical and chemical influences. In the long run, this can result in damage to the film and the print contained on the film.
    [0013] Plastic glazing for vehicles are typically produced in multi-component injection molding methods. Often, these glasses include, in the edge region, a dark colored opaque component, usually black, over a transparent component, with the side of the glass that has the opaque material side always facing the interior of the vehicle. In the region of the opaque component, the glazing can be connected to the vehicle body, for example, glued, invisibly from the observer's point of view. Unlike prior art vehicular glazing made of mineral glass, these opaque edge regions in plastic glasses are often larger in area and more complex in design. In these regions of the glazing, this grants the ability to introduce optical ornamental elements and decorations into the glazing.
    [0014] The aim of the invention is to provide a method for producing a plastic vehicle connection piece with an impression that is protected from external influences.
    [0015] The object of the invention is carried out by a method according to claim 1. Preferred embodiments arise from the sub-claims.
    [0016] A plastic vehicle connecting piece according to the invention and the use of a plastic vehicle connecting piece arise from other independent claims. Preferred embodiments arise from the subclaims.
    [0017] The method, according to the invention, for producing a plastic vehicle connection part comprises a first step, in which a polymeric film is extended into an injection mold. In the context of the invention, the term "film" includes both single and multi-component homogeneous films as well as woven, woven or layered multi-component films or textiles made of different or identical materials. The polymeric film is preferably fixed by electrostatic interactions onto the steel surface of the injection mold. Electrostatic charge is preferably transferred without contact with the polymeric film, via charging electrodes which are supplied with high voltage by charge generators. Alternatively, the polymeric film can be attached to the injection mold mechanically or via vacuum suction. The polymeric film has an opaque or semi-opaque print or color pigmentation. The print is preferably stable to decomposition at a temperature of at least 250 °C, preferably at least 320 °C. In the context of the invention, the term "semi-opaque print" also includes color prints and gray color gradation prints. The opaque print preferably contains a printing ink with temperature-stable organic pigments, for example, urethane-acrylate polymers, carbon, azo dyes, or polycyclic compounds. Alternatively, inorganic pigments such as titanium dioxide, carbon black, cinnabar, bismuth- (bismutovanadate), spinel pigments, lead, mercury, zirconium, iron, cadmium, copper, cobalt, nickel, chromium pigments; ALUMINOSILICATES (OVERSEAS), may be included. Due to the higher temperature stability, inorganic pigments are preferably used. In an alternative embodiment, the color pigments can even be homogeneously incorporated within the polymeric film. This can be done, for example, by mixing the color pigments into a granulate of the polymeric film with subsequent extrusion of the resulting mixture. In another possible option, the color pigments can be sprayed in a solution onto the polymeric film.
    [0018] In the second step of the method according to the invention, the polymeric film is re-injected with a phase of transparent polymeric material, which forms the covering part of the plastic vehicle connection piece. The liquid starting material of the polymeric coating part is injected onto the polymeric film in the injection mold, and a material bond between the polymeric film and the coating part is thus obtained. The polymeric coating part is implemented optically transparent. Optical transparency gives the polymeric coating part a glass-like appearance, but with a low weight and high shaping ability. In the context of the invention, “transparent” means that an observer can look through the component and can recognize objects that are situated behind the component from the observer's point of view. The transparent component can be colorless. The transparent component can also be colored or dyed. The transmittance of the transparent polymeric coating part in the visible spectral range (300 nm - 800 nm) is at least 10%.
    [0019] In a third step, a part of the polymeric carrier is sprayed onto the composite structure of the polymeric film and the polymeric coating part. The polymeric carrier part is sprayed onto the side of the polymeric coating part on which no polymeric film is applied, in other words, the material sequence is polymeric film - polymeric coating part - polymeric carrier part. The polymeric carrier part ensures the stability of the vehicle connecting plastic part and includes polymeric materials with the highest possible strength, hardness, impact strength, or notched impact strength, and low fracturing ability.
    [0020] The surface which is formed by the polymeric film and polymeric coating part, i.e. the surface on which the print is visible, is defined as the first exposed surface of the vehicle connecting plastic piece. The surfaces of the vehicle connecting part which are on the outside of the part, after production of the part consisting of the polymeric coating part, polymeric carrier part and the polymeric film, are referred to as exposed surfaces. These surfaces can be coated later in the process. The surface which is opposite the first surface, i.e. the surface which is formed by at least the opaquely implemented polymeric carrier part, is defined as the second exposed surface of the vehicle connecting plastic piece. The term "exposed side surfaces" means the edge surfaces of the part that surround the individual material layers of the polymeric coating part and the polymeric carrier part.
    [0021] The polymeric carrier part can be sprayed onto the entire surface of the polymeric coating part, for example by a column cover or a door panel. In this case, the second exposed surface is formed by the polymeric carrier part. The polymeric carrier part can even be arranged only in a sub-region of the polymeric coating part, for example, in the case of a plastic vehicle window pane which has a black region in the edge region of the pane, which is formed by the polymeric carrier part. In this case, the second exposed surface is formed by the polymeric carrier part and the polymeric coating part.
    [0022] In another step, a protective coating (hard coating) is applied over the vehicle connecting piece. The protective coating is applied at least over the polymeric film to protect the film and the included print. The protective coating is preferably applied all the way around, in other words all exposed surfaces, including side surfaces of the vehicle connecting piece. Preferably, heat-curing or UV-curing varnish systems based on polysiloxanes, polyacrylates, polymethacrylates and/or polyurethanes are used. The protective coating may have one or a plurality of layers applied separately, and preferably has a total layer thickness of 1 µm to 50 µm, particularly preferably 2 µm to 25 µm. The particular advantage lies in the scratch resistance and weather resistance as well as the chemical resistance of the polymeric workpiece due to the protective coating. The protective coating can also include UV blockers, preservatives as well as scratch-enhancing components, eg nanoparticles. In addition, the protective coating can also take on decorative functions, such as glitter or pearl effects. The protective coating can, for example, be applied over the polymeric workpiece by dipping, flooding, or spraying methods, or an in-mold coating process. The protective coating is cured after application, preferably by temperature and/or UV light input.
    [0023] In an optional final step, the vehicle connection piece can be overmolded or partially overmolded with a soft component. The soft component preferably has thermoplastic elastomers (TPE, TPV), thermoplastic olefins (TPO), thermoplastic polyurethanes (TPU), polyvinyl chloride (PVC), thermoplastic polyester polymers (TPC), or styrene block copolymers (TPS) and can be colored when desired.
    [0024] Thus, an improved vehicle connection plastic piece is provided, which includes an imprint that is protected from external influences and is clearly visible. At the same time, a glass-like effect is produced by the transparent cover part, so that the vehicle connecting piece is suitable not only for internal and external components in the area of the panels, for example as a column column cover B or C, but which can also be used as a colored window pane. The arrangement of the printed film on the transparent cover part prevents, with the presence of dark coloration of the transparent phase, that the print color is distorted. With the use of the vehicle connecting piece as a tinted window glass (eg in the case of privacy glazing), this arrangement has the advantage that the print is clearly visible and - unlike an arrangement under the transparent cover part - is clearly discernible with no color changes.
    [0025] The vehicle connecting plastic part is preferably produced in the multi-component injection molding process or in the multi-component injection compression process, particularly preferable in combination with turntable, rotary table, and/or index plate technology. Alternatively, the plastic vehicle connection piece can also be produced using only turntable, rotary table, and/or indicator plate technology.
    [0026] The polymeric carrier part preferably contains polyethylene (PE), polycarbonates (PC), polypropylene (PP), polystyrene, polybutadiene, polynitriles, polyesters, polyurethanes, polymethyl methacrylates, polyacrylates, polyamides, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), preferably, acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylester (ASA), acrylonitrile butadiene styrene - polycarbonate (ABS/PC), PET/PC, PBT/PC, and/or copolymers or mixtures thereof.
    [0027] The polymeric carrier part is preferably implemented opaque. Thus, the contrast of the print included on the polymeric film is improved compared to a transparent implementation of the carrier part. In the context of the invention, "opaque" means that an observer cannot see through the components. The transmittance of the opaque carrier part in the visible spectrum is thus significantly reduced and is preferably less than 10%, preferably less than or equal to 5%, in particular approximately 0%.
    [0028] The polymeric carrier part is preferably injection molded in a thickness of 0.5mm to 10mm, particularly preferably of 1mm to 5mm. The thickness of the polymeric carrier part depends on the dimensions and stability requirements of the finished component.
    [0029] The polymeric coating part is preferably injection molded in a thickness of 1mm to 10mm, preferably 2mm to 5mm. In this range, a glass-like effect, which is particularly pronounced visually, is obtained.
    [0030] The polymeric film preferably contains polycarbonates (PC), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycarbonate - polybutylene terephthalate (PBT/PC), styrene acrylonitrile (SAN), and/or copolymers or mixtures thereof. The polymeric film preferably contains the same material as the polymeric coating part, since with the back-injection of the polymeric film with the polymeric coating part, the film is connected without transition to the polymeric coating part, a situation which is particularly advantageous of a visual point of view.
    [0031] The polymeric film preferably has a thickness from 0.1 mm to 3 mm, preferably from 0.12 mm to 1 mm. The surface area of the polymeric film can vary depending on the print to be applied and the sizing of the polymeric carrier part and the polymeric coating part. The polymeric film can extend over the entire surface of the coating part, i.e. the entire first exposed surface is formed by the polymeric film. Alternatively, the film may extend over only a subregion of the first exposed surface so that an edge region remains free of the polymeric film. Preferably, the film extends over a region from 2% to 80%, preferably from 3% to 30%, particularly preferably from 5% to 15% of the entire surface of the polymeric coating part. A film that extends over only a sub-region of the polymeric coating part has the advantage that the latter can be fixed by adhesion to the injection mold without additional fixing measures being necessary. In the case of relatively small films, the risk of air bubbles being trapped during the re-injection of the film, or of the film being indeterminate by injection molding compound, is minimized. The vehicle connecting piece can thus be produced more efficiently.
    [0032] However, the film may particularly preferably also extend over the print region only.
    [0033] In another preferred embodiment, the polymeric film comprises a plurality of individual polymeric films with a decorative imprint, wherein each of the individual polymeric films extends over a subregion of the polymeric coating portion. Thus, using a simple process, relatively complex composite decorative prints can be integrated into the component.
    [0034] With the use of the vehicle connecting part as a vehicular window, the print is preferably applied in the region of the carrier part, so that the driver's view through the transparent window region is not impaired by the print. The polymeric film is preferably preformed, particularly preferably thermally preformed. Previous conformation of the polymeric film allows better adaptation with the geometry of the injection mold cavity and the coating part. Furthermore, this prevents infiltration of the polymeric side between the polymeric coating part and the polymeric film during polymeric film back-injection into the polymeric coating part.
    [0035] The invention further includes a plastic vehicle connection piece comprising at least an opaque polymeric carrier part, a transparent polymeric coating part, a polymeric film, and a protective coating on the polymeric film. The polymeric film is arranged on the transparent polymeric coating part, with the polymeric film having an opaque or semi-opaque print. The polymeric carrier part is applied on the side of the clearcoat part which has no polymeric film, i.e. the carrier part is applied onto the surface of the clearcoat part which is opposite the polymeric film. The polymeric carrier part ensures the stability of the vehicle connecting plastic part and includes, as described above, polymeric materials such as polyethylene (PE), polycarbonates (PC), polypropylene (PP), polystyrene, polybutadiene, polynitriles, polyesters, polyurethanes, polymethyl methacrylates, polyacrylates, polyamides, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), preferably acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylester (ASA), acrylonitrile butadiene styrene - polycarbonate (PCB/PC) , PBT/PC, and/or copolymers or mixtures thereof.
    [0036] The polymeric carrier part preferably contains inorganic or organic fillers, particularly preferably SiO2, Al2O3, TiO2, clay minerals, silicates, zeolites, glass fibers, carbon fibers, glass beads, organic fibers, and/or its mixtures. Charges can further increase the stability of the carrier. In addition, fillers can reduce the content of polymeric materials and thus reduce part production costs.
    [0037] The polymeric coating part can support both decorative functions and functions in the area of component strength. Examples of these are surfaces or coatings that increase weather, UV or chemical resistance. The polymeric film serves as an opaque or semi-opaque print carrier. The print can be applied on the side of the film that points to the injection mold at the time of placement inside the injection mold, so that, on the finished vehicle connecting part, the printing ends above the first exposed surface of the connecting part of finished vehicle. Alternatively, the print can also be attached to the side of the film that points to the transparent polymeric coating part, whereby the print is not directly exposed to external influences. In the case of a multilayer film, the print can even be arranged between two individual film layers, whereby the print is somewhat protected, on the finished vehicle connecting piece, against external influences. The print is preferably stable to decomposition at at least 250°C, preferably 320°C, as otherwise the print or the colored pigments would decompose or fade during spraying onto the polymeric coating part. The opaque or semi-opaque print is preferably stable to thermal decomposition in the range of 150°C to 350°C, particularly preferably 200°C to 320°C. The polymeric film is also preferably stable to decomposition at at least 150°C, particularly preferably at least 320°C, otherwise gas bubbles and discolorations could form in the region of the polymeric film in the finished workpiece.
    [0038] The polymeric film is preferably stable to thermal decomposition in the range of 200 °C to 320 °C. Here, suitable film materials are mainly polymethyl methacrylate (PMMA) and polycarbonate (PC). These polymeric films can be oversprayed with a variety of clear polymers that form the coating part. The polymeric film may, in an alternative embodiment, also be colored, black or gray.
    [0039] The polymeric film preferably does not extend over the entire surface of the polymeric coating part. Preferably, an edge region of at least 0.1 cm to 5 cm without polymeric film is arranged. The filmless edge region ensures an even edge seal. Furthermore, the edge region can support decorative functions.
    [0040] The invention further includes the use of a plastic vehicle connection piece for internal and external applications in vehicles, preferably for external application. The vehicle connecting plastic piece is preferably used as A, B or C column covers on vehicles, particularly preferable as a tinted window pane on vehicles. The use of a plastic vehicle connection piece as a radiator grille panel or as a spoiler element is also possible.
    [0041] The invention is explained in detail with reference to drawings and exemplary embodiments. The drawings are purely schematic representations and are not to true scale. The drawings in no way restrict the invention.
    [0042] They represent the following.

    [0048] Fig. 1 represents a schematic view of a plastic vehicle connecting piece according to the invention, for example a B-pillar cover of a motor vehicle. A clear polymeric coating part 3 made of PC or PMMA is arranged over an opaque polymeric carrier part 4 made of acrylonitrile butadiene styrene (ABS). The transparent polymeric coating part 3 produces a glass-like effect with a depth effect on the surface of the opaque carrier part 4. A polymeric film 1 of 0.5mm thick with a decorative print 2 is arranged on the coating part. transparent polymeric 3. The polymeric film 1 does not extend over the entire surface of the polymeric coating part 3. An edge region with a width of approximately 0.2 cm is free of polymeric 1, in which middle an improved edge seal is obtained. A protective layer 5, eg a polysiloxane based varnish, is arranged on all exposed surfaces I and II and side surfaces III of the plastic vehicle connection piece. The protective layer 5 protects the polymeric film 1, the polymeric coating part 3, and the polymeric carrier part 4 against damage from mechanical and chemical influences. The exposed side surfaces III are also coated with a protective layer 5 and protected against external influences. It is discernible in the cross-section of the part according to the invention that the polymeric film 1 is surrounded in the edge region of the part by the material of the polymeric coating part 3, and that the polymeric film 1 is embedded in the transparent coating part 3 This stable fixation of the polymeric film 1 without a visible transition with the polymeric coating part 3 is made with the re-injection of polymeric film 1 with the hot material of the transparent coating part 3.
    [0049] Fig. 2a represents a schematic view of a plastic vehicle glazing according to the invention. In the region of the glass edge outside the field of view, vehicle window panes often include an opaque, obscurely colored component over a transparent component. In the region of the opaque component, the glazing can be connected to the vehicle body invisibly from the observer's point of view. This dark region is formed in the example according to the invention by a black carrier part 4 made of a PC/ABS mixture in a thickness of 2.5 mm. In this thickness, the carrier part 4 of the vehicle glazing provides the vehicle window glass with the necessary thickness. A transparent cover part 3 made of polycarbonate in a thickness of 4 mm is applied over this carrier part 4. In this thickness, there is sufficient impact resistance, which is necessary for use as a vehicular glazing. The transparent cover part 3 can be colored when it is necessary, for example in the field of privacy glazing. A polymeric film 1 with a decorative print 2 is arranged on the polymeric transparent cover part 3. As can be seen in fig. 2b, the polymeric film 1 is embedded in the polymeric coating part 3 and is applied only above the carrier part 4, in order to obtain a good contrast of the decorative print 2 in front of the opaquely implemented carrier part 4. An edge region with a width of 0.1 cm is free from polymeric film 1, in order to obtain particularly good edge sealing. A protective layer 5 containing a polysiloxane varnish is arranged on the polymeric film 1 and the transparent cover part 3 on the first exposed surface 1. This varnish protects the polymeric film 1 and the decorative print 2 against abrasion, wear and damage. By coating the polymeric coating part 3 with a rigid polysiloxane coating, it is possible to satisfy the very high demands that are usually only imposed in safety glazing (Rigid Plastic Glazings, ECE R43 Annex 14, Class /M). In the example shown, varnish is applied to all exposed surfaces I, II, and III of the vehicle window pane in order to improve the scratch resistance of the glass on the first and second exposed surfaces and also to protect the side surfaces exposed III of the vehicle glazing.
    [0050] Fig. 3 represents a flowchart of the method according to the invention for producing a plastic vehicle connection piece according to the invention. In a first process step, a polymeric film 1 is provided with an opaque or semi-opaque print 2 stable to decomposition at a temperature of 320 °C. Print 2 is preferably applied via a screen printing or inkjet printing process. The polymeric film 1 is then stretched into an injection mold and re-injected with a clear polymeric coating part 4 (the liquefied polymeric material of the polymeric coating part). In a final step, a polymeric carrier part 4 is sprayed onto the polymeric film 1 and the polymeric coating part 3. After curing of the polymeric coating part 3 and the polymeric carrier part 4, a protective layer 5 (hard coating ) is applied to improve mechanical and chemical resistance. The hard coating can be applied by flooding, spraying or dipping. The protective layer 5 is applied on the first exposed surface I, i.e. on the polymeric coating part 3 and the polymeric film 1, and on the second exposed surface II, i.e. at least on the polymeric carrier part 4. In the case of roofing with a hard polysiloxane coating, even very high requirements, which are generally imposed only in safety glazing (hard plastic glazing, ECE R43 Annex 14, Class /M), can be satisfied.
