    Method for manufacturing structured press elements.
    This invention relates to a method for manufacturing structured press elements that can be used in the manufacture of coated decorative panels.
    More specifically, the invention relates to the manufacture of press elements used in a method for manufacturing coated panels, wherein the coated panels are of the type comprising a substrate and a decorative top layer applied thereto. This may, for example, concern floor panels which mainly consist of a substrate, for example an MDF or HDF (Medium or High Density Fiberboard) panel and a top layer applied thereto, such as a laminate top layer.
    In particular, the invention relates to pressing elements that are used in a method for manufacturing coated panels with a printed decor with a transparent or translucent plastic layer extending above. It is known that such a decor, whether or not with the intervention of soil layers, can be printed directly on the substrate. However, the decor can also be provided on a material sheet, such as a paper sheet or a plastic film, which is included in the aforementioned top layer. The transparent or translucent plastic layer forms a protective layer above the printed decor and may contain, for example, wear-resistant particles such as aluminum oxide. It is not excluded that this protective layer also contains a material sheet, such as a paper sheet or plastic film. It may, for example, involve the manufacture of laminate floor panels, for example according to a DPL (Direct Pressure Laminate) or HPL (High Pressure Laminate) technique. In the case of a DPL technique, one or more resin sheets of material are introduced together with the substrate into a pressing device where they are connected to each other and to the substrate by means of a pressing element and under the action of increased pressure and temperature. In the case of an HPL technique, the top layer is formed separately on the basis of two or more resinous material sheets,
    BE2017 / 5690 before the top layer thus obtained is applied to the substrate, for example by gluing it to the substrate. According to another possibility, it may involve the manufacture of plastic-based floor panels or floor coverings, such as, for example, vinyl panels, vinyl coverings and the like.
    It is known, for example from WO 01/96689 or WO 2014/115086, that a relief of embossed sections can be formed on the surface or the decorative side of such coated panels, with which, for example, the natural structure of the motif shown in the aforementioned decor can be formed be imitated. For example, in the case that the decor represents a wood motif, it is possible to work with a relief that imitates a wood structure. Such a wood structure can possibly be in accordance with the underlying decor, with which so-called impressions are then obtained in register with the printed decor.
    As known, structured press elements are used to realize a relief on the decorative side. Various techniques are known for the manufacture of such pressing elements, for example from WO 2006/066776, EP 2 123 476, EP 2 251 193, EP 1 987 395 and EP 2 834 076. A method is known from EP'395 known for manufacturing structured press elements, the method comprising at least the following steps:
    - the step of providing an element of metal;
    the step of applying a mask to a surface of the element for shielding portions of said surface;
    - the step of chemically processing non-shielded portions of the aforementioned surface of the element; and
    - the step of removing the aforementioned mask.
    The pressing elements obtained on the basis of the methods from the state of the art still leave something to be desired, in particular when they are used for realizing relatively deep structural parts in the surface of the relevant pressing element, for example with structural parts with a depth greater than 0.15 millimeters.
    BE2017 / 5690
    The present invention contemplates an alternative method for manufacturing press elements which, according to various preferred embodiments of the invention, can offer advantages over the prior art.
    To this end, the present invention according to its first independent aspect relates to a method for manufacturing structured press elements, the method comprising at least the following steps:
    - the step of providing an element of metal;
    the step of applying a mask to a surface of the element for shielding portions of said surface;
    - the step of processing, preferably chemical processing, such as etching, of non-shielded portions of the aforementioned surface of the element;
    - the step of removing the aforementioned mask;
    characterized in that the method comprises at least one step in which the aforementioned surface of the element is subjected to an ultrasonic treatment. It is clear that the mask in question is at least to some extent resistant to the subsequent processing step, such that substantially the non-shielded portions are processed.
    The ultrasonic treatment preferably takes place in a bath, wherein the aforementioned element or at least at least the aforementioned surface is immersed in a liquid. The ultrasonic waves that are sent by the liquid in question lead to air bubbles that implode against the surface to be treated. A particularly effective treatment of the surface in question is thus obtained, wherein the imploding air bubbles also have a mechanical effect on the surface. Preferably the liquid is a degreasing agent such as an alkaline degreasing agent. The ultrasonic treatment used according to the invention is primarily aimed at cleaning or degreasing the surface in question, but other effects such as a surface treatment for obtaining a certain dullness or gloss are not excluded. The applied frequency range of the ultrasonic treatment is preferably between 20 and 100 kHz, and even better between 25 and 50 kHz. An ultrasonic treatment at a frequency in the lower range, for example
    BE2017 / 5690 of 20 to 30 kHz, or about 25 kHz, leads to a powerful surface treatment, while ultrasonic treatment at the higher frequencies, for example between 40 and 50 kHz, or about 45 kHz, leads to a finer surface treatment .
    In a step following the aforementioned ultrasonic treatment, whether or not in the bath, the pressing element, or at least at least the treated surface, is preferably rinsed one or more times, for example with water, hard water or a degreasing agent. Hard water is preferably used for the rinsing. This results in a very effective cleaning. Preferably the hard water contains a concentration of minerals of more than 40 mg per liter, or more preferably more than 60 or more than 80 mg / l.
    According to the invention, the ultrasonic treatment can be used in various ways, two preferred options of which are described below.
    According to a first possibility, the step of removing said mask comprises said ultrasonic treatment. Ultrasonic treatment makes it possible to remove hard masks more effectively and quickly. Very good cleaning and / or degreasing is obtained with deep structural sections. Particularly when the treatment is applied, with the surface in question immersed in a liquid, the action of the imploding bubbles leads to a very effective breaking of the mask. It is noted that the use of hard masks is mainly advantageous in the manufacture of press elements with deep structural parts, for example deeper than 0.15 mm, since in such cases the mask is exposed for a long time to the relevant operation, for example an etching operation. It is clear that the ultrasonic treatment of the invention is also effective for the removal of softer masks, which can be used, for example, if the aforementioned operation is a blasting operation.
    BE2017 / 5690
    According to a second possibility, the method further comprises the step of pre-treating the aforementioned surface before the aforementioned mask is applied, the pre-treatment step comprising said ultrasonic treatment. The inventors have determined that such pre-treatment leads to an improved adhesion of the mask to the surface in question. Preferably a surface tension of 48 mN / m or more is achieved, for example between 50 and 60 mN / m, such as 52 to 54 mN / m. This improved adhesion and increased surface tension may be due, on the one hand, to the removal of impurities from the surface, and, on the other hand, to the limited relief obtained by the mechanical impact of imploding bubbles when the treatment is carried out in a bath. Improved adhesion is interesting with masks that are exposed for a long time to the subsequent processing step, for example in the case of realizing deep structural sections, for example in the realization of structural sections with a depth of more than 0.15 mm. It goes without saying that improved adhesion due to the removal of impurities is also interesting with less deep structures, such as with structural depths of a few hundredths of a millimeter, for example 0.02 mm deep, or with polished surfaces, since in such cases the mechanical adhesion is minimal is.
    Of course, it is not excluded that in the method of the invention several ultrasonic treatments of the surface in question would be carried out, for example at least one treatment according to the above first possibility and at least one treatment according to the above second possibility.
    It is clear from the foregoing that the method of the invention is preferably used for the manufacture of pressing elements comprising structural sections with a depth of 0.15 mm or more, or even of 0.4 mm or more. Preferably, when removing said mask, the aforementioned pressing element has structural portions with a depth of 0.15 mm or more. Structure portions with a depth of 0.15 mm or more are preferably realized in the aforementioned processing step, which means that material is removed during this step over a depth of 0.15 mm or more.
    BE2017 / 5690
    The starting element from metal can be designed in various ways, some of which are listed below.
    According to a first possibility, the element is a flat element of metal, preferably of steel, namely a steel plate. Such an element can have an overall thickness of 1.5 to 10 mm. The starting point can have a flat surface to be treated. For example, it can be a ground surface. According to a variant, the element that is assumed can have a surface to be treated that has already been preformed, for example by means of a milling and / or laser treatment.
    According to a second possibility, the element is a roller or drum whose surface consists of at least metal, for example copper. Also in this second possibility, the casing of the roller or drum can be flat or preformed.
    According to a third possibility, the element is a metal, for example steel, band, which may or may not already be attached to each other with the ends for forming an endless band. Also in this third possibility, the ultimately outward facing surface of the endless belt can be flat or preformed.
    The step of applying the mask is preferably carried out by means of a digital printing technique directly on the surface of the aforementioned element, preferably by means of an inkjet technique. For example, a printing technique similar to that of EP 1 987 395 can be used. A digital printing technique makes it simple to mask flat or non-preformed flat and non-flat elements.
    Preferably, the aforementioned mask is constructed from an acrylate-containing or acrylate-based substance. Acrylates lead to a considerably harder mask than, for example, UV-cured gel, wax or paraffin layers, which according to the state of the
    BE2017 / 5690 technique, for example in WO 2006/066776, are used for the realization of etching masks. The initial adhesion and achievable resolution of such a mask is also better, whereby sharper structural portions can be achieved in the processing step. In addition, such masks are resistant to a wider spectrum of operations, including FeCh etching, sandblasting, electro-polishing, glass blasting, and so on. Preferably, in the case of a mask applied by means of a digital printing technique, the substance to be applied for the construction of the mask comprises 10 to 60% by weight, preferably at least 20%, from acrylates, and preferably further still before 10 to 60% from a reactive solvent monomer and / or adhesion promoter, such as morpholine, for example acryloyl morpholine. The substance to be applied can of course also comprise other components. The substance is, irrespective of whether it contains acrylates or not, preferably UV-curable, namely by ultraviolet radiation, or EB-curable, namely by means of electron beams. For example, immediately after printing, the substance can already be cured at least partially by one or more UV sources or EB sources that are located in the immediate vicinity of the print heads, for example mounted on these print heads. This so-called "pin-cure" leads to an optimal initial adhesion of the relevant mask portions and a high resolution. The inventors have further established that an acrylate-containing, whether or not UV or EB-curable, substance can also be cured further or completely by IR radiation, namely by infrared radiation. Preferably, a mask that has already been cured by means of UV or EB pin-cure is still subjected to a further cure by IR radiation. Such a way of working leads to extremely hard and stable masks.
    It is obvious that within the scope of the invention it is also possible to work with a mask made up of gel, wax, hot-melt adhesive or paraffin. Preferably, in such a case, it also concerns a UV-cured substance, such as a UV-curing wax or hot-melt adhesive.
    BE2017 / 5690
    As has already been mentioned several times, the invention is of particular interest when pressing elements with deep structural parts, for example with a depth of more than 0.15 mm or even of 0.4 mm or more, are to be realized, this depth preferably being achieved during the step of editing the non-shielded portions. This means, in other words, that during the processing step material is removed over a depth of more than 0.15 mm or more than 0.4 mm respectively. The ultrasonic treatment makes it possible to work with harder, and therefore more resistant, masks, so that a wider spectrum of processing techniques can be applied and / or a longer exposure to these processing techniques can be applied.
    The processing performed on the relevant surface of the element during the processing step preferably comprises an etching and / or a blasting operation such as a sand or glass blasting operation. In the etching operation, use is preferably made of an etching liquid containing FeCh. The etching operation is preferably carried out at a temperature between 30 ° C and 75 ° C, for example at 45 ° C to 55 ° C, with 50 ° C being a good value. The mask used can be tailored to the operation to be performed. For example, for an etching operation, a relatively hard mask is preferably opted for, while for a blasting operation, a softer mask is preferably opted for. As a hard mask, a mask can be used based on a UV-cured lacquer. As a soft mask, a mask can be used that has been obtained by air drying from a water-based emulsion or dispersion of a lacquer, such as from an acrylate-based or acrylate-containing lacquer.
    The curing or post-curing of masks by infrared radiation per se constitutes a second aspect of the invention, wherein this second aspect relates to a method for manufacturing structured pressing elements according to the first aspect or the preferred embodiments thereof, characterized in that the step of applying the mask comprises at least one treatment with infrared radiation. It is clear that this second aspect has preferred embodiments corresponding to the
    BE2017 / 5690 preferred embodiments of the first aspect, regardless of whether or not ultrasonic processing is used herein.
    According to a particular embodiment of the first and the second aspect, the step of processing involves a step in which the non-shielded portions of the aforementioned surface are chemically processed, this step of chemical processing being carried out with the aforementioned surface facing down. Such a method of operation prevents the formation of puddles or films of saturated etching fluid or other chemically active product on the surface to be treated, thereby losing the uniformity or effectiveness of the chemical processing. Because the surface to be treated is directed downwards, the removed material and the active product, for example the etching fluid, are simply discharged. A rapid drying of the surface is achieved. Pointing the surface to be treated downward in an etching operation forms a third aspect of the present invention. To this end, the third aspect of the invention relates to a method for manufacturing structured pressing elements according to the method of the first and / or the second aspect, characterized in that the step of chemical processing is carried out with the aforementioned surface facing downwards.
    In the case of one of the above aspects, as is the case in the third aspect, that the chemical processing step is carried out with the aforementioned surface facing downwards, the chemically active product is preferably applied to the surface by means of one or more nozzles. surface to be processed. The element, or at least at least the surface thereof to be processed, is therefore preferably not immersed in the chemically active product or etching fluid in question. The aforementioned nozzles are preferably arranged on one or more shuttles with a width smaller than the width of the surface to be treated, wherein these shuttles scan the relevant surface at least by moving back and forth over the aforementioned surface in the aforementioned width, one strip extending over the width is treated, the relative position between element and shuttle is adjusted longitudinally, and another at
    BE2017 / 5690 preferred strip is treated. According to a variant, the aforementioned nozzles are arranged on one or more beams which extend over the full width of the aforementioned element. In this way a treatment of the entire surface can be obtained in a single relative movement of the beam relative to the pressing element. Preferably it is the beam that moves. Regardless of the arrangement of the nozzles, one or more or all of the nozzles preferably perform an oscillating movement transverse to the relative movement of the nozzle and surface to be treated; in other words, in the case of nozzles positioned on a shuttle, an oscillation transverse to the movement of the shuttle, and, in the case of nozzles positioned on one or more beams, an oscillation transverse to the relative movement of the beam and to be treated surface. Such oscillating motion creates an overlap between the zones treated by adjacent nozzles, or between the zones or strips treated by successive movements of the shuttle. Such overlap prevents or minimizes any non-uniform treatment.
    In the case of a chemical processing, the chemical processing step is preferably carried out in at least two sub-steps, wherein in a first step chemically active product is applied to the aforementioned surface at a temperature of more than 35 ° C, for example at approximately 45 ° C, and wherein in a second step chemically active product is applied to the aforementioned surface at a temperature of less than 30 ° C, for example at about 20 ° C. Preferably, the highest temperature is used first, followed by the lower temperature. In practical terms, such an embodiment can be realized on the basis of two shuttles that are active one after the other, or on the basis of two beams arranged one after the other. According to a variant, spray nozzles can be arranged on the same shuttle, one behind the other in the direction of movement, which apply chemically active product of different temperatures. The inventors have found that applying at least two sub-steps in which chemically active substance of different temperature is applied to the surface of the element leads to a reduction of oxide formation and also to a somewhat sharper etched structure.
    BE2017 / 5690
    Preferably, residual products from the aforementioned step of chemically processing the surface in question are removed by means of a blower and / or rinsing device. Such removal preferably takes place immediately after the application of the chemically active product, for example in that the bladder and / or flushing device is mounted on the aforementioned shuttle. With a rinse immediately after the application of the chemically active product, for example within 15 seconds, the formation of oxides is reduced. This is because air can act on the treated surface for less time.
    Preferably, the aforementioned chemical processing step is repeated several times, with material being etched from the surface in question with a depth of preferably 20 to 120 micrometres per step. Because thin layers are etched one after the other, a sharper image can be obtained. Herein, each step can per se consist of the sub-steps mentioned above in which chemically active substance of different temperatures is applied. Preferably, residual products are removed from the respective surface after each step, for example by means of a blower.
    It is clear that the pressing elements that are manufactured according to the various aspects of the invention are preferably used in a method for manufacturing coated panels, wherein these panels are of the type comprising at least a substrate, a decor and a top layer based on of plastic, the method comprising at least the following steps:
    - making the relevant pressing element with a method according to one or more of the preceding aspects or the preferred embodiments thereof, wherein said pressing element is provided on its surface with a structure or relief;
    forming the aforementioned coated panels, wherein the aforementioned pressing element is used to form pressed portions in the decorative side of the coated panels by means of the aforementioned relief, and more particularly in the decorative side of plates from which such coated panels can then be obtained .
    BE2017 / 5690
    Preferably, for the material of the pressing element of the invention, metal, such as a steel alloy or a copper alloy, is used.
    The step of forming the coated panels preferably uses the DPL technique described above.
    In a particularly preferred embodiment, the pressing element is provided with a relief which has the shape of a wood structure.
    It is clear that the use of the pressing elements of the present invention is not limited to the manufacture of coated panels that represent a wood structure or wood pattern. The present invention can also be used when the printed decor and the associated structure are stone motifs, or a stone structure, or when it concerns fantasy motifs or fantasy structures, respectively.
    Moreover, the pressing elements made according to the present invention are particularly interesting when the aforementioned decor represents a motif and when the aforementioned relief and motif of the aforementioned decor are mutually consistent, such that said embossed portions in the decorative side at least partially follow the aforementioned motif or at least partially coincide with this. This concerns printed sections which are arranged so-called "in register" with the underlying motif of the, preferably printed, backdrop. This embodiment makes it possible to obtain particularly convincing imitations of, for example, solid wood.
    The present invention is by no means limited to the embodiments described above, but such methods and pressing elements can be realized according to different variants without departing from the scope of the present invention.
