Definitions

  • the invention relates to cork panels, which comprise a carrier plate, a cork lining and a wear layer, wherein a surface structure is formed in the cork lining. Furthermore, the invention relates to a method for producing such cork panels.
  • US 2014/01 9661 8 A1 (Floor Iptech) describes a method for structuring and printing surfaces and also surfaces of floor panels. However, the embossing process described there is not applied to cork surfaces.
  • EP 2 082 897 B1 (Schulte) and EP 2 039 530 B1 (Schulte) describe a stamping process for cork boards and the result of this method.
  • the cork panels are printed with a decor.
  • cork is elastic and has a high rebound behavior. At normal temperatures, therefore, an embossed structure can only be produced to a limited extent in the cork layer or the results are unsatisfactory. Therefore, the two documents propose to heat the cork layer to 40 ° C to 80 ° C.
  • a seal can be applied. The seal is a varnish, oil or wax layer.
  • none of the known methods allows the production of embossed cork panels, in which the surface structure is produced only after the application of a wear layer.
  • the order and the distribution of the wear layer material are influenced by the structures, for example, the material collects in the structures. This is undesirable because the wear layer material does not process (e.g., smooth) in the same manner as it does on flat surfaces. Due to the different processing and / or by an uneven distribution of the wear layer primarily the optical properties of wear layers can change massively. For example, streaks or "orange peel" appear, which is usually undesirable.
  • the object of the invention is to provide a structured cork panel belonging to the technical field mentioned at the outset and a method for its production, in which a high-quality wearing layer is obtained at different levels Structures can be produced and therefore the wear layer is influenced only in their form by the structure r.
  • the cork panel comprises a carrier plate, a cork lining and a wear layer, wherein a surface structure a is formed in the cork lining.
  • the cork lining is preferably a press cork and this preferably has a density of between 400 and 550 kg / m 3 , in particular a density between 450 and 500 kg / m 3 .
  • a smaller density leads to a lower durability of the press cork for a floor covering and this can have more rapid unevenness.
  • the cork has a higher density, the comfort properties of the cork suffer.
  • Such comfort properties are, for example, the low heat conduction, which leads to warm feet, and the damping, protects the joints and effectively reduces impact sound m. Since the wear layer is formed before structuring, it is unaffected by the surface structures during its production. Since the structures are then produced by a non-material-removing method, the wear layer is not significantly influenced by the introduction of the structuring.
  • it is a cold stamping, that is, a surface structure, which is formed by the local application of a high pressure at room temperature or a slightly higher temperature of preferably not more than 70 ° C.
  • Certain wear layers are less sensitive to temperature. These are, in particular, wear layers below a heat-applying, highly viscous wearing layer or below the paints which determine the degree of gloss.
  • a cork panel, on which at the time of embossing such a low temperature-sensitive wear layer was applied, can be embossed with up to 1 50 ° C.
  • the pressure is preferably between 3 and 10 kg / cm 2 .
  • the pressure used in the individual case is determined on a sample by a series of experiments. The tests showed that the stamping of pressed cork is considerably better than that of natural raw cork.
  • the embossability increases with decreasing size of the pressed cork particles. With a preferred average cork particle diameter between 1 and 3 mm, for example, a printable and stampable cork lining can be produced.
  • the density of the cork particles seems to influence the embossability: denser cork particles and pressed cork, which is made of denser cork particles, can be better embossed and keeps the structures better than less dense cork particles and press cork containing them.
  • a cork particle granules having a bulk density of between 80 and 100 kg / m 3 , particularly preferably of 90 kg / m 3 are used for an embossable cork lining.
  • the surface structure is deeper than 0.2 mm, preferably between 0.3 and 0.5 mm, deep.
  • a pressure layer is located between the cork lining and the wear layer.
  • the print layer may be a layer of ink applied directly to the cork pad or an intermediate layer.
  • the print layer does not have to cover its underlay completely. For example, it is possible that the cork flooring is only printed with individual lines, but outside these lines the cork flooring or an intermediate layer is visible.
  • the printing layer can also be a printed nonwoven or a printed paper or a similar carrier.
  • the carrier can be placed directly on the cork lining or separated by intermediate layers of the cork lining.
  • the carrier is preferably connected by an adhesive to the layer immediately above it.
  • the support like the layer of ink, can also be applied only in parts.
  • the wear layer is a wear layer which is highly viscous during application. Such a wear layer must be smoothed after application, otherwise no even surface is formed.
  • the wear layer is preferably a moisture-curing polyurethane.
  • the material of the wear layer is preferably a material having a dynamic viscosity of more than 5000 mPas at the application temperature.
  • the wearing layer contains high-strength particles, in particular ceramic particles.
  • the wear layer preferably also contains abrasion-resistant particles, such as, for example, corundum or ceramic. Ideally, these particles should be uniformly distributed in the support material and should maintain this uniform distribution even during the curing of the wearing layer.
  • a wear layer of a relatively liquid material can not hold the particles in suspension during curing. The particles sink or rise, depending on the relative density of particles and useful layer material.
  • the material of the wearing layer can spread so thinly that the particles are no longer enveloped by the material. But with reduced abrasion resistance of the layer. It may be necessary filler layers above and below the wear layer, which allow smooth surfaces.
  • a highly viscous wearing layer can keep the particles evenly distributed during curing, but even without particles, a highly viscous wearing layer can be advantageous over the use of more liquid layers (e.g., abrasion resistance and impact resistance) when applied.
  • the interaction between the highly viscous wear layer and the roller with which the wearing layer is typically applied creates unsightly streaks and patterns on the panels. These are removed by a smoothing roller or a smoothing or similar methods again.
  • automatic smoothing is only possible without problems if the surface of the utility layer is even. Therefore, highly viscous wear layers can only be applied to unstructured surfaces or only on surfaces whose structures are either significantly smaller than the wear layer thickness or so large that the smoothing tool can reach into it. At the desired depth of the structures of more than 0.2 mm, both criteria are not met. Therefore, only the embossing after the application and the smoothing of the wear layer allows the use of a highly viscous wearing layer.
  • a highly viscous wearing layer can hold and contain larger particles than a conventional wearing layer.
  • the particles preferably have an average particle diameter of more than 90 ⁇ m, in particular of 100 ⁇ mol or more, if they are kept in a highly viscous wear layer.
  • Abrasion-resistant particles in other wear layers are preferably smaller and, for example, between 1 and 30 ⁇ m in diameter.
  • the particle size can be determined, for example, by sieving or by light scattering.
  • highly viscous is meant in this context in particular a dynamic viscosity of more than 5000 mPa s and that in the usual Application temperature of the wear layer.
  • the manufacturers of the wear layer materials indicate the application temperature. It is typically between 100 ° C and 1 50 ° C.
  • One possible material suitable for the wear layer of cork panels and highly viscous is moisture-curing polyurethane.
  • a viscosity of 8000 +/- 2000 mPa s at 140 ° C. was measured on the day of production with the Brookfield HBTD Viscometer at 10 rpm.
  • the viscosity is measured with this device and this rotational speed, and preferably also in each case on the day of production of the wear layer material.
  • the cork panel further comprises a cork base of preferably 1 to 2 mm thickness, which is located opposite the cork lining on the support plate.
  • Such a cork backing is a counterbalance, which compensates for the stresses caused by cork lining and coatings on the top. This prevents the panels from bulging. Furthermore, the cork pad can dampen the impact sound and protect the carrier plate from moisture.
  • the carrier plate is a medium density fiberboard (MDF) or a high density fibreboard (HDF) or a waterproof plate.
  • MDF medium density fiberboard
  • HDF high density fibreboard
  • carrier plates are stable and are not damaged during the embossing process. They combine well with the cork flooring and the cork backing. At their edges, a groove and a spring can be formed from them, which allow a click connection or a conventional, glued connection.
  • the cork lining has a thickness of more than 0.5 mm and preferably between 0.5 and 3 mm.
  • the cork covering should be thicker than the desired embossing structures. At the same time unnecessarily thick panels should be avoided. Thicknesses are between 0.5 and 3 mm a good compromise and also allow the panels to feel like cork flooring, for example in terms of pedaling comfort and heat conduction.
  • the material of the cork lining is a strongly compressed mixture of cork granules and a PU adhesive.
  • the material of the cork lining has a density of more than 450 kg / m 3 , in particular a density between 600 and 700 kg / m 3 .
  • Such a cork flooring is strong enough and sufficiently closed to serve as a floor covering and to allow printing or the inclusion of a decorative layer.
  • the density is not high enough for the user to lose the feeling of a cork panel.
  • the cork lining cushions which explains the high pedaling comfort.
  • the cork granules have grain sizes between 0.5 and 3 mm, in particular between 1 and 3 mm, diameter.
  • the PU adhesive is advantageously a mixture of a very hard and elastic adhesive.
  • the very hard adhesive preferably has a dynamic viscosity greater than 4500 mPa s and the elastic adhesive has a dynamic viscosity of less than 2500 mPa s during processing.
  • the cork pad consists of a less densely compressed cork granules than the cork lining.
  • the cork pad should not be printed. It may therefore have a coarser intrinsic structure.
  • the cork underlay should provide good heat insulation and enable good impact sound damping. Both are achieved by a less dense cork granules.
  • the cork panel has the following structure from bottom to top: a. A cork pad; b. a support plate; c. a cork flooring; d. a primer; e. a digital print; f. another primer; G. a wear layer of a material which is very viscous when applied and can therefore be applied thickly and which can hold larger ceramic particles without significantly changing their distribution in the wear layer during drying; H. a UV primer; i. one or more coats of paint that determines the gloss level. An embossing is introduced only after the curing of all these layers.
  • the cork pad serves as a countermove.
  • the support plate provides the necessary stability and preferably has fasteners such as tongue and groove or click-connection means.
  • the cork flooring creates the cork floor feel and provides a sufficiently smooth surface to allow the application of additional layers.
  • the primer helps to preserve the printing ink and to enhance its color.
  • the print layer serves the optical design.
  • the further primer produces an optimal connection between printing layer and wear layer.
  • the wear layer is in turn highly viscous and contains uniformly distributed particles.
  • the UV primer allows a well-adhering and uniform application of the following lacquer layers on the wear layer. Since the primer cures under UV light, its curing time can be chosen deliberately.
  • the Coating layers determine the gloss level of the panels. Since the embossing is introduced only after the curing of all layers, all layers have the desired thicknesses. None of the coatings accumulates in depressions or must be specially applied consuming.
  • the cork panel has the following structure (bottom to top): a. a cork pad; b. a carrier plate; c. a cork flooring; d. a primer; e. a digital print; f. a UV primer; G. a filling layer with polished section; H. a wear layer of a basecoat with ceramic particles; i. a filling layer with a polished section and a flat surface between and on the ceramic particles, j. two varnishes, possibly partially sanded to adjust the gloss level
  • this embodiment is identical to that previously described.
  • the wear layer here is less viscous during application and can therefore be produced with a smaller thickness. It is therefore embedded in two filling layers, of which the lower is sanded before applying the wear layer. So she can be a part of Keep ceramic particles and the basecoat. The top layer allows a flat surface and further embeds the ceramic particles. The polished section of this second filling layer allows good adhesion to the following coatings, which in turn determine the gloss level of the cork panels. Again, the late embossing allows a simple and even application of all layers.
  • a method of making cork panels involves the following steps: a. The coating of the cork covering with a utility layer; b. at a later date, embossing the coated cork flooring.
  • the cork flooring is coated. Between the cork lining and the wear layer further layers can be applied. Layers from the application of liquid material are preferably applied with rollers or nozzles or brushes, wherein the material hardens after application.
  • the curing can be done by cooling, by the Konta kt to the ambient air, by UV irradiation and the like, or combinations thereof. Different materials may have different viscosities when applied. Viscosity may also change with age and environmental conditions, especially temperature. Typical materials that are liquid when applied are paints, inks, fillers, and wearing-course materials.
  • a solid material during application may be present in webs of material which have been applied.
  • Such a solid material may be, for example, a nonwoven for stabilization or a Dekorpa pier.
  • the cork lining is embossed together with all layers that it carries.
  • the embossing is done by the local exercise of pressure.
  • the embossing preferably causes structures deeper than 0.2 mm.
  • the cork lining is applied to a carrier plate before coating with a wear layer.
  • the cork pad is applied to the backing plate with a conventional adhesive and applying pressure and possibly heat. The result is a durable and flat connection between cork flooring and carrier plate.
  • the cork lining Since the carrier plate is more stable than the cork lining, so the cork lining is mechanically stabilized. Due to the embossing process, the material of the cork lining can be locally weakened and therefore breaks or tears easier during further processing. By the cork lining is first connected to the carrier plate and only then embossed, the carrier plate stabilizes the possibly locally weakened cork lining. In addition, the further processing step of applying to the carrier plate after the embossing process is eliminated. Damage to parts of the cork panel is thus prevented. Alternatively, the cork coating can be applied after coating with the wear layer but before embossing on the carrier plate.
  • embossing of the coated cork lining takes place at a temperature between 20 ° C. and 1550 ° C., preferably, especially in the case of a highly viscous wear layer, at a temperature between 20 ° C. and 90 ° C., in particular at a temperature of 50 ° C. 70 ° C.
  • a heating of the cork lining or the wear layer preferably does not take place when the room temperature is greater than or equal to 20 ° C. This protects the different coatings, which can be partially liquefied by heat and / or behave differently under heat. However, temperatures of up to 90 ° C, especially up to 70 ° C, can tolerate the different layers in general, and since this temperature range can be used. It was surprisingly found in experiments that the cork lining against all expectations even at room temperature or temperatures up to 90 ° C, in particular up to 70 ° C, emboss and the structures thus produced also maintains over time. A permanent structuring of the cork lining can therefore be produced with the method according to the invention.
