    Summary
    The invention provides a floor covering element comprising an insulating layer (1) facing the floor in use, a carrier layer (2) made of canvas arranged on the insulating layer (1) and connected to the insulating layer (1), the carrier layer (2) at least the top is coated with a primer (3a), a top layer (3) at least partially a pressure layer (4) for the optical design of the floor covering element, and a transparent seal (5) is arranged on the top layer (4) , wherein the surface structure of the seal (5) is predetermined by the carrier layer (2) made of canvas and has a surface roughness (Sa) of at least 7.5 μm, in particular at least 8.0 μm, preferably at least 9.4 μm.
    Fig. 1/17
    The invention relates to a printed, multilayer floor covering element.
    Flooring elements are used, among other things, to achieve heat and impact sound absorption, to protect the floor from signs of wear and to enable individual interior design. In order to create a warm, homely atmosphere, the haptic properties of the flooring element are also important, since smooth surfaces appear cold and rough materials are easily perceived as scratching. The floor covering element should have a non-slip surface and should be easy to clean. At the end of product life, a flooring element should be reusable or recyclable to avoid creating large amounts of waste to be disposed of.
    A wide variety of floor covering elements, such as carpets or floor mats, are known from the prior art. On the one hand, carpets made of fiber materials with pile and loops of different heights are known, e.g. "Oriental carpets", or flat-woven carpets, such as "Patchwork carpets". These have good insulation properties and create a warm atmosphere. However, they get dirty quickly and are difficult to clean, since they can usually only be cleaned locally by laboriously dabbing or because of their material composition they have to be brought to professional cleaning, which is time-consuming and expensive.
    On the other hand, freely placeable or extensively laid floor coverings made of vinyl, PVC and linoleum are known. Such wet-wipeable floor coverings are severely limited in their individual design due to the manufacturing processes. Even known functional mats with a multilayer structure do not meet the need for a combination of high-quality functional, aesthetic and haptic properties and, due to their material and assembly properties, can be recycled hardly or not at all.
    DE 202015004860 U1, for example, shows a floor mat with an adhesive layer for sticking to a floor, a design element and a non-slip surface element, the non-slip effect being achieved by lamination or embossing. Such surfaces tend to become soiled when used continuously. The surface element severely limits the individual design freedom, since the design element is not clearly visible, but because of the lamination or embossing the color quality is impaired and boundaries are only indistinctly / 17 recognizable. Furthermore, the haptic properties are not suitable, a warm one
    Create atmosphere and there is no insulation effect.
    Known flooring elements cannot meet all the requirements placed on them.
    The object of the invention is therefore to provide a flooring element which has heat and impact sound damping, is anti-slip, easy to clean, in particular can be wiped with a damp cloth, and which can be designed individually and has a pleasant feel.
    According to the invention, the object is achieved by a floor covering element comprising an insulating layer facing the floor in use, a carrier layer made of canvas arranged on the insulating layer and connected to the insulating layer, the carrier layer being coated with a primer at least on the top, at least on the top primer partially a print layer for the optical design of the floor covering element is applied, and wherein a transparent seal is arranged on the print layer, the surface structure of the seal being predetermined by the carrier layer made of canvas and a surface roughness (Sa) of at least 7.5 μm, in particular at least 8 , 0 μm, preferably at least 9.4 μm.
    The structure according to the invention enables the requirements placed on a floor covering to be met. On the one hand, the insulation layer offers heat and impact sound insulation. In addition, it can be prevented that the canvas is deformed due to use or unevenness and crumbs that get under the flooring element and that such deformations damage the seal when subjected to further stress.
    The primer protects the canvas from moisture damage, e.g. Deformations. The primer also enables a sharp print image that is visible through the transparent seal. This allows the flooring element to be designed individually. The seal is water and dirt repellent and enables easy cleaning because the floor covering element can be wiped off with a damp cloth. The surface roughness specified by the canvas does not affect cleaning. In addition, this can provide a non-slip surface that has pleasant haptic properties.
    / 17th
    The construction according to the invention also enables the floor covering element to be rolled up and is easy to transport in this way without the
    Functionality is impaired. This enables particularly flexible use.
    Canvas is a tightly woven fabric made of strong yarn and is made from natural fibers such as cotton, hemp or linen. It is also possible to produce from mixed fibers with polyester, polyacrylic, etc., whereby pure natural fibers are preferred due to the better adhesion of the primer and for reasons of sustainability. Canvas is produced in different weaves, e.g. in plain weave, in half-Panama weave, Panama weave, or ripstop. Each of these bonds is suitable for the invention and implies the desired surface roughness.
    The perception threshold for haptic properties is around 1 μm, i.e. surface structures can be perceived up to this small size. The surface roughness can be determined as a Sa value, the arithmetic mean of the heights of the selected area being determined by light microscopic measurement. The surface roughness (Sa) is determined according to ISO 25178, e.g. using an Alicona Infinitive Focus Microscope (IFM). The surface roughness according to the invention is felt to be particularly pleasant.
    Advantageous configurations result from the following features:
    It can be provided that the floor covering element has a thickness between 2 mm and 7 mm, in particular between 2 mm and 5 mm, preferably between 2.5 mm and 4.5 mm. Due to the small thickness, the floor covering element can be used particularly flexibly, since it can also be used in the door area without obstructing the opening or closing of a door. The floor covering element is therefore suitable both as a surface covering and as an exposed limited floor covering. For example, the flooring element can be used as a table mat or desk mat. It is particularly easy to transport due to the small thickness, without affecting the stability.
    In order to obtain a particularly good slip resistance, it can be provided that the carrier layer made of canvas with a weight per square meter between 350 g / m 2 and 850 g / m 2 , in particular between 450 g / m2 and 800 g / m2, preferably between 500 g / m2 / 17 and 750 g / m 2 . Additionally or instead, the carrier layer made of canvas can have a thickness of at least 0.6 mm, in particular of at least 0.7 mm, preferably of at least 0.8 mm. As a result, a stable floor covering element with particularly good slip resistance and pleasant haptic properties can be provided.
    In order to prevent the backing layer from being deformed by the action of moisture, the backing layer can be coated on both sides with the primer or a bottom-side primer can be applied to the underside of the backing layer facing the insulating layer. The underside primer also improves the connection between the support layer and the insulation layer, since in the case of a support layer coated on both sides, the support layer is connected to the insulation layer via the underside primer. The primer on the underside prevents the lanyard from penetrating deeply into the canvas base layer, so that the insulation layer can be completely detached from the base layer by pulling it apart. This is particularly advantageous, since different materials can usually only be recycled separately, so that reuse or recycling is possible at the end of product life, while known floor covering elements often have to be disposed of.
    It is particularly suitable if the primer consists of acrylic gesso. Additionally or instead, it can be provided that the primer is designed as a coating comprising calcium carbonate and acrylic polymer, and in particular titanium white pigments. On the one hand, such a primer can protect the canvas backing well from moisture, while the surface roughness is only slightly affected. The primer is furthermore particularly suitable for the adhesion of the printing layer or, if appropriate, also for connection to the insulating layer. Furthermore, a particularly clear and sharp print image can be created on the primer.
    A particularly resistant and stable flooring element can be obtained if the seal consists of parquet lacquer. Additionally or alternatively, it can be provided that the seal is designed as a coating comprising polyurethane-acrylate copolymer and / or a polyurethane and / or a polyacrylate. This gives the flooring element a particularly waterproof, dirt-repellent and easy-to-clean surface that can be cleaned, for example, by wiping or vacuuming. In addition, a particularly suitable hardness can be achieved to avoid scratches, while at the same time a good flexibility can be obtained in order to prevent the flooring element from being damaged by cracks when it is rolled up. Even if it is damaged, it is
    Sealer easy to repair or replace.
    The seal can preferably have a thickness of 80 μm to 100 μm. As a result, the surface roughness specified by the canvas is retained, while depending on the area of application, the stress classes ÖNORM C 2354 A, B or C (moderate, strong or particularly heavy stress) can be met.
    The seal has in particular a surface roughness (Sa) of up to 14 μm, preferably up to 11 μm. This surface roughness allows a particularly good anti-slip effect with easy cleaning and good stability. In addition, the surface roughness is felt to be particularly pleasant and non-scratchy.
    In order to simplify the use of the floor covering element for living rooms, in particular also for children's rooms, it can be provided that the seal is saliva-resistant and acid-resistant.
    A particularly clear and sharp print image can be obtained if the print layer consists of a latex ink. Additionally or instead, it can be provided that the printing layer is designed as a coating comprising latex and pigments, and in particular a styrene-acrylate copolymer. These inks are very lightfast and abrasion resistant. This can prevent ink from collecting in depressions in the surface structure. On the one hand, the surface roughness is particularly well preserved, and uniform drying can be achieved. The ink is also odorless and harmless to health. The print layer can preferably be applied using the digital printing process, so that the individual design is particularly simple and efficient, since a known and widely used technology can be used.
    In order to obtain a particularly stable floor covering element, it can be provided that the insulation layer has a height of 2 mm - 5 mm. On the one hand, this thickness enables great flexibility, while at the same time good heat and impact sound insulation can be achieved. In particular, it can be provided that the insulation layer consists of a, preferably natural, felt, in particular with a hardness of M3 to F3 (DIN 61200). A / 17 flame-retardant effect can be achieved with natural felts, especially with wool admixture. In addition, such felts have particularly good insulating properties. This effect is reinforced by the special hardness. In addition, uneven floors are particularly well compensated for and wrinkles can be avoided during use. In this way, the load on the sealant can be reduced and the durability of the flooring element can be improved.
    In order to further increase the durability of the floor covering element, it can be provided that the insulation layer is glued to the carrier layer, preferably over a large area. In the case of a carrier layer coated on both sides, the carrier layer is glued to the insulation layer via the primer on the underside. Moisture penetration into the flooring element can be avoided by the adhesive. This also makes the flooring element particularly stable. The surface roughness of the carrier layer serves as a mechanical anchor, the peaks of which are subjected to mechanical pressure from above, e.g. by walking on the floor covering element, parked objects or furniture, by pressing on the adhesive surface underneath increases the stability of the connection, since loosening of the connection is prevented by diametrically shifting the layers by means of mechanical force due to the mountains “sunk” into the rubberized adhesive by drying can.
    Additionally or alternatively, it can be provided that the insulating layer can be completely separated from the carrier layer, so that further use or recycling at the end of product life is simplified. If the carpet is to be recycled, the insulation layer and backing layer can be manually separated by pulling them apart. Adhesive residues remain on the insulation layer. This can e.g. find further use as sealing material. The carrier layer can, for example, continue to be provided with a new insulation layer, or, for example, can also be ground and resealed. Then, for example, use as a table cover is possible, or it can also be combined with a new insulation layer as a heat-insulating wall hanging. At the end of product life, the carrier layer can be used for thermal recycling.
    A good adhesion with simultaneous good separability can be obtained if an adhesive is applied comprising for the connection between the insulating layer and the carrier layer, or the primer on the underside
    - rubber and / 17
    a stabilizer, in particular ammonia, preferably 0.1% by weight - 0.5% by weight ammonia, and
    - A crosslinking system, in particular a fatty acid, preferably lauric acid, and / or a metal oxide, preferably zinc oxide, and / or a thiuram disulfide, preferably, tetramethylthiuram disulfide.
    The same effect can be achieved if an adhesive comprising natural rubber, rosin-glycerol ester, linseed oil, casein, xanthan and thiazoles is applied for the connection between the insulating layer and the carrier layer, or the primer on the underside.
    With this special adhesive, a stable flooring element can be provided that is easy to recycle.
    A particularly advantageous embodiment of the invention is shown by way of example with reference to the drawing without restricting the general inventive concept.
    1 shows the structure of an exemplary floor covering element according to the invention.
    In Fig. 1, a floor covering element is shown, with an insulation layer 1, which faces the floor when in use. In the illustrated embodiment, the insulation layer 1 is made of a wool felt. Alternatively, a wool-polyester mixture (e.g. 30% wool, 70% polyester) could be used. The insulation layer 1 is connected to a carrier layer 2 made of canvas.
    In the illustrated embodiment, the insulation layer 1 is connected to the carrier layer 2 by an adhesive 6, liquid adhesive, ie an aqueous dispersion of rubber with approximately 0.2% ammonia and a mixture of lauric acid, thiram and zinc oxide, being provided as the adhesive. Alternatively, a pasty adhesive, e.g. based on natural rubber milk. Another type of gluing is also possible, e.g. with tapes.
    In the embodiment shown, the canvas is made of untreated cotton yarn that is woven in a plain weave. This has a particularly advantageous surface roughness and is particularly easy to coat with the primer. In principle, any other canvas can also be used as carrier layer 1, for example canvas of thicker quality with more than 1 mm thickness (e.g. # 6 number duck or # 4 number duck), of consistently thicker but coarser weave structure and / or / 17 of greater weight (e.g. 610 g / m 2 or 710 g / m 2 ). For example, cotton-polyester mixtures (e.g. 80% cotton, 20% polyester), etc. be used.
    The carrier layer 2 is coated on both sides with a primer 3 in the embodiment shown. The carrier layer 2 therefore has a bottom-side primer 3b facing the insulation layer 1 and an opposite top-side primer 3a. The primer 3 comprises calcium carbonate and acrylic polymer and titanium dioxide. The primed carrier layer 1 has a weight of 619 g / m 2 in the embodiment shown. In another embodiment, when using stronger canvas, for example, # 8 has a weight of 740 g / m 2 or # 6 has a weight of 820 g / m 2 .
    In the embodiment shown, a pressure layer 4 is arranged on the top primer 3a facing away from the insulation layer 1. In the embodiment shown, the printing layer 4 is arranged over the entire area on the top-side primer 3a and is formed by a latex ink.
    The print layer 4 is completely covered by a transparent seal 5. In the embodiment shown, the seal 5 is made of a polyurethane-acrylate copolymer-based composition. In another embodiment, the seal 5 can also be based on a composition comprising polyurethane or a composition comprising polyacrylate.
    The surface structure of the seal 5 is predetermined by the carrier layer 2 made of canvas. In the embodiment shown, the seal 5 has a surface roughness (Sa) of 9.4 μm.
    An exemplary method for producing a floor covering element according to the invention is shown below:
    First, untreated canvas is coated as a base layer 2 with a primer, preferably on both sides, which forms the primer 3a, 3b. A printing layer 4 is applied to one side of the primed carrier layer 2, for example using a latex ink in the digital printing process. A seal 5 is applied over the entire surface of the print layer 4. The carrier layer 2 is connected to the insulation layer 1, an adhesive 6, preferably flat, being applied to the insulation layer 1 and the carrier layer 2 being arranged such that the seal 5 is arranged on the side facing away from the insulation layer 1. The application of the adhesive / 17 between the insulation layer 1 and carrier layer 2 is independent of the others
    Procedural steps and can be done at any time.
    The following can be done in detail:
    A base layer 2 made of canvas is used for a floor covering element according to the invention, the canvas used being made of cotton yarn woven in plain weave and having a weight of 514 g / m 2 and a thickness of 0.8 mm.
    The canvas is coated with acrylic gesso on both sides with a triple surface covering. A conventional acid-free primer with calcium carbonate (CaCO 3 ), acrylic polymer (medium latex) and titanium white is used. The carrier layer 2 coated with the primer 3 has a weight of 610 g / m 2 , a thickness of 0.83 mm and an average surface roughness Sa (ISO 25178) of 10.4 μm on both sides.
    The coated carrier layer 2 is printed on one side, on the later upper side, using a known latex digital printing technology with a decorative motif. Inks are used that are available under the trade name HP 881 latex inks. These form a flat printing layer 4, which is arranged on the top primer 3a.
    As insulation layer 1, a wool felt layer of 2 mm thickness (according to DIN 61206), 30 g / ccm density (according to DIN 61200) and 600 g / m 2 weight (according to DIN 61200) and M5 hardness (according to DIN 61200) is provided. An adhesive 6 is applied to the insulation layer 1 on one side.
    A product available under the trade name AURO Flooring Adhesive No. 382 is used as adhesive 6, which is applied to the surface using a short-hair roller or toothed spatula (fine A3). After a maximum drying time of 20 minutes at a room temperature of 22 ° C. and an average air humidity of 50%, the unprinted underside of the prepared carrier layer 2 is arranged on the insulation layer 1. In this case, the primer 3b on the underside is arranged on the adhesive surface and the insulation layer 1 is connected to the backing layer 2 in this way, the layers being adhesively bonded to one another by means of calenders under a roller pressure of 3-4 bar. The carrier layer 2 is arranged in such a way that the pressure layer 4 is arranged on the upper side facing away from the insulating layer 1.
    / 17th
    The top with the print layer 4 is sealed for better durability, a clear parquet lacquer being used as the seal 5, which is available under the trade name ADLER 42140 ff. The seal 5 is painted in three layers using a short hair roller to a total dry film thickness of 80-100 μm. 300 g / m 2 parquet lacquer is used for the first layer, 200 g / m 2 for each of the subsequent layers. There is an intermediate drying time of at least 30 minutes between the individual layer applications at a room temperature of 22 ° C and a humidity of 50%.
    After double application, intermediate sanding with Kö 400 sanding paper is possible. Alternatively, sealing 5 can be applied using airless or airmix sprayers (0.28-0.33 mm nozzle, 100-120 bar / 1-2 bar, approx. 30 s) or compressed air sprayers (1.8 mm - Nozzle, 3-4 bar, approx. 20 s) possible in a painting chamber or as the core element of a housed, automated painting system. The seal 5 can also be applied, for example, before the adhesive layer 1 is bonded.
    After a final drying time of eight days, the floor covering element is waterproof, abrasion-resistant (ÖNORM C 2354 category C, very heavy duty) and sealed to sweat and saliva in accordance with ÖNORM S 1555 and DIN 53160. The flooring element has an average surface roughness of 9.4 μm and a total thickness of 3000 μm. The flooring element can be cut to the desired dimensions.
    The edges can be designed individually (e.g. hem seam, bias tape, fold, or trimmed flush with the room). For example, the edges can be stitched in a tricot stitch or triple zigzag stitch. For example, a particularly robust industrial sewing thread made of polytetrafluoroethylene (PTFE) can be used (1400 denier / 1556 dtex, needle size: NM 100-120, thread size: approx. 35-40NM, nominal maximum tensile force 4448 cN / ~ 4) , 5Kg, thread diameter: 0.35mm).
    A changed procedure is also possible, e.g. the edges are designed before painting. For example, first the insulation layer 1 is connected to the primed carrier layer 2, then the printing, the cutting and the edge design take place and only then the sealing 5.
    / 17th
    The flooring element according to the invention is durable, flexible, slip-resistant, has a pleasant feel and good heat and
    Impact sound absorption, it is easy to clean and can be designed individually.
