Description

[0001] The invention relates to a floor panel which has a carrier plate with a decorative layer on the top.

[0002] According to DE 10 2013 113 478 A1, a floor, wall, or ceiling panel comprising a core board and a decorative layer on top is considered state-of-the-art. The core board consists of a composite material made of fibers and a hydraulic binder. The decorative layer consists of a natural material-reinforced plastic. In particular, the core board is a fiber cement board or a magnesite board. The core board and the decorative layer are hot-pressed together.

[0003] Furthermore, DE 10 2005 017 392 A1 discloses a floor panel comprising a core board and a top layer. The core board consists of a mineral material, particularly gypsum, cement, or rock flour.

[0004] DE 199 44 399 A1 also discloses a floor panel. The carrier board described therein is made of polyurethane or acrylate as a binder and fillers. Mineral fillers, such as lime, quartz, sand, and the like, are used.

[0005] DE 10 2014 002 154 A1 discloses a building slab, particularly for use as a floor, wall, or ceiling slab, comprising a carrier plate with locking contours on the edges and a surface layer made of a mineral material. The surface layer is intended to comprise at least one layer of fiber cement.

[0006] EP 0 608 400 B1 describes a laminated structure produced under heat and pressure with a core consisting of a fiber cement board. The decorative layer comprises a resin-impregnated paper interlayer, to which a resin-impregnated decorative overlay layer is laminated. However, depending on the application, cement- or cement-fiber-based core boards do not offer the best strength and rigidity.

[0007] The state of the art also includes the floor covering made of floor panels, as described in DE 20 2005 020 617 U1. The floor panels have a core made of a mineral material into which a reinforcing material is embedded. The floor panels have mechanical locking devices on the side edges.

[0008] A duct component for ventilation pipes or ducts is the subject of DE 100 39 859 A1. The wall of the duct component is made of compacted rock wool or mineral wool to improve its soundproofing, fire protection, and thermal properties.

[0009] According to CH 669 005 A5, an insulation system and an insulation board are considered state-of-the-art. The insulation boards are mineral fiber boards, specifically rock wool boards, coated with an organic coating material on at least one side. To allow installation of the insulation boards into the insulation system, which consists of shells made of in-situ concrete, they have stepped seams on their ends.

[0010] Based on the prior art, the invention is based on the object of providing a floor panel which is further improved in terms of its mechanical properties, which is highly stable, low in warpage and insensitive to moisture and has very good fire resistance.

[0011] The solution to this problem according to the invention consists in a floor panel according to claim 1.

[0012] Advantageous embodiments and further developments of the component according to the invention are the subject of dependent claims 2 to 17.

[0013] The core board is made of pressed and compacted rock wool. The side edges of the core board are profiled and equipped with locking devices.

[0014] The decorative layer is formed from a bonded powder mixture. The powder mixture contains a powder in a proportion of between 30% and 70%. The powder mixture also contains color pigments, corundum, and resins, particularly thermosetting resins, in powder form.

[0015] The powder is a fine or very fine, free-flowing bulk material. The term powder also includes powders and dusts. In particular, the powder comprises biomaterial particles, preferably wood particles. Other biological or mineral powders, for example stone particles and the like, can also be used within the scope of the invention. In this context, powders resulting from the production of the carrier plate or from the mechanical processing of the carrier plate to produce the locking means can also be used as a component of the powder mixture of the decorative layer. This therefore involves stone flour or stone powder or rock wool powder or dust. Mineral natural stone components are also possible and well-suited as powders, for example powders based on mica, granite, dolomite or the like.

[0016] The powder preferably has a particle size of less than or equal to (≤) 500 µm. As already explained, the powder is a fine or very fine, free-flowing bulk material, whereby powder also includes powders or dusts. An elongated fibrous structure, for example, in wood fiber particles, is also a powder within the meaning of the invention. The particles of the powder can have a round or angular shape, for example, cubic. Cubic particle shapes occur, for example, in crushed quartz sands.

[0017] The resin in the decorative layer is in particular a thermosetting resin, preferably a urea resin or a melamine resin.

[0018] According to the invention, the carrier plate and the decorative layer are pressed together.

[0019] The advantageous aspect of the invention consists in the combination of the carrier plate made of compacted rock wool and the decorative layer made of bound powder or powder mixture.

[0020] According to one aspect of the invention, the carrier plate has a density of greater than or equal to (≥) 800 kg / m3 (kilograms per cubic meter), in particular the density of the carrier plate is between 800 kg / m3 and 1500 kg / m3, preferably between 900 kg / m3 and 1400 kg / m3.

[0021] Furthermore, the carrier plate has a transverse tensile strength of greater than or equal to (≥) 2.5 N / mm2 (Newtons per square millimeter), in particular between 2.5 N / mm2 and 6.0 N / mm2. The transverse tensile strength is particularly preferably between 3.5 N / mm2 and 5.0 N / mm2.

[0022] According to the invention, the carrier board has a moisture absorption capacity of less than or equal to (≤) 5% based on its initial dry weight. In particular, the moisture absorption capacity is between 1.0% and 3.0%. This moisture absorption capacity ensures, on the one hand, that moisture generated during the pressing of the decorative layer and the carrier board can diffuse into the carrier board, i.e., is absorbed by the carrier board. On the other hand, the low moisture absorption capacity makes the building element insensitive to moisture. This also makes the building element suitable for installation in damp rooms.

[0023] A practical, advantageous design provides for a multi-layered decorative layer. For this purpose, several layers of powder can be applied to the carrier plate. The multiple layers of powder are then pressed together with the carrier plate. Furthermore, it is also possible to incorporate layers of other materials, such as nonwoven layers or paper layers, especially decorative paper, into the decorative layer. These are also pressed together with the powder layer and the carrier plate under pressure and temperature.

[0024] One aspect of the invention provides that the decorative layer has at least two layers of powder mixture. Here, at least two of the multiple layers of powder mixture have different compositions. In particular, the resin content and / or the resin itself in the two layers differs from one another. In particular, the lower layer can have a higher resin content than the powder mixture of the layer arranged above it. The resin content in the lower layer is between 40% and 70%. The resin content of the layer arranged above is lower and lies between 35% and 55%. Furthermore, the powder mixture of the lower layer can contain a more reactive resin than a layer of powder mixture arranged above it. The measures outlined above improve the bond between the carrier plate and the decorative layer, in particular through a coordinated reactivity of the resin with regard to the curing time and the amount of resin.

[0025] A further advantageous embodiment of the invention provides for a flat substrate to be incorporated between the carrier plate and the decorative layer. The flat substrate can be, in particular, a paper layer, for example, a special cellulose paper or unprinted paper, or even a nonwoven layer. A resin-impregnated flat carrier substrate, in particular one impregnated with thermosetting resins, is particularly preferably used. During production, the powder mixture of the decorative layer can be applied to the flat substrate and, together with it, to the carrier plate or the original carrier plate. It is also possible to first position the flat substrate on the carrier plate and then apply the powder mixture to it.

[0026] The thickness of the core board is between 4 mm and 12 mm. The preferred thickness is 5 mm to 8 mm. However, core boards with larger dimensions up to 15 mm, 20 mm, or 25 mm can also be used. For flooring applications, core boards with thicknesses between 5 mm and 8 mm are preferred.

[0027] A further aspect of the invention provides for a counter-layer beneath the support plate. This counter-layer supports the structural stability of the building element and serves as a moisture barrier and impact sound insulation.

[0028] The counterlayer can be made of the same material as the decorative layer. The counterlayer is then formed from a bonded powder mixture. The powder mixture contains powder, preferably biomaterial particles, and resin. Color pigments and corundum can also be included in the powder mixture of the counterlayer.

[0029] The locking means on the side edges of the support plate can be formed from the same material as the support plate. For example, the locking means can be designed in the form of a tongue and groove or as a so-called click connection with locking tongues and locking tabs. Furthermore, the locking means can be designed as a two-part system and, in particular, comprise sliding springs or locking elements.

[0030] In a surface covering made of panel-shaped building elements, especially a floor covering, the locking elements of adjacent building elements engage with each other. This creates a gap-free, glue-free, and tensile- and compressive-resistant connection between the installed building elements.

[0031] The installation process of components can be improved by applying a lubricant to the side edges of the support plate, particularly in the area of ​​the locking means. For this purpose, an oil, wax, or other lubricant with good sliding properties, such as Teflon, can be applied to the side edges.

[0032] The moisture stability and resistance of a component according to the invention is improved. According to the invention, a sealant is applied to the side edges of the carrier plate, particularly in the area of ​​the locking means.

[0033] This can also be oil, wax, or something similar. In particular, the impregnation with a sealant is applied all the way around, both along the long and head edges. This measure supports reliable protection against moisture.

[0034] Liquids or gel-like substances modified with nanomaterials can also be used as lubricants and as sealants for moisture impregnation.

[0035] In this context, it is also possible to geometrically design the side edges of the carrier plate, particularly in the area of ​​the locking means, in such a way that fluid passage is prevented. For this purpose, the locking means are provided with grooves, webs, bevels, and / or undercuts that prevent fluid circulation or passage.

[0036] The practical application of a component according to the invention can be further improved if the underside is profiled or structured. In particular, the underside is roughened by profiling or has an embossed structure. Profiling the underside gives it a structure that is advantageous for adhesive bonding. The component according to the invention is therefore particularly well suited for adhesive bonding to a substrate using suitable adhesive systems.

[0037] It is possible to bond the components using polyurethane. Commercially available tile adhesives can also be used. As already mentioned, the adhesive installation is supported by the profiling or embossed structure on the underside of the component, which enables mechanical interlocking with the adhesive system.

[0038] The component according to the invention is moisture-resistant and exhibits very good fire behavior. Practical tests suggest that the component will be classified as flame-retardant in terms of fire behavior.

[0039] The carrier plate and the decorative layer are pressed together, in particular hot-pressed. To produce the components, a large-format starting carrier plate made of compacted rock wool is provided. The powder forming the decorative layer is then applied, in particular sprinkled, to the upper surface of the starting carrier plate. The powder layer can be preconditioned on the starting carrier plate before pressing. This is achieved by applying heat and / or moisture, for example, through a liquid mist. The powder mixture reacts and forms a film that adheres to the surface of the starting carrier plate. The cured powder mixture has a film-like structure with a skin on top. This semi-finished layer can be printed with the starting carrier plate before pressing; preferably, the printing is carried out using digital printing and an ink system tailored to the resin of the decorative layer.

[0040] Optionally, the counter-layer can be arranged underneath the initial support plate. For example, a layer of powder can be applied underneath the initial support plate.

[0041] It should be noted again at this point that the decorative layer can be multi-layered and comprise two or more layers of a powder mixture. Furthermore, a layer in the form of a flat substrate, for example, a paper or nonwoven layer, preferably a resin-impregnated carrier substrate, can also be part of the decorative layer. A multi-layer structure is both functionally and visually advantageous.

[0042] The multilayer body, which consists of at least the base plate and a powder layer on top, is then pressed in a press under the influence of temperature and pressure. During the pressing process, the powder or components of the powder, namely the resin, are plasticized and cured. The plasticization and curing of the powder mixture forms the decorative layer. The decorative layer is firmly bonded to the base plate. The powder mixture is adjusted so that moisture generated during pressing can escape or evaporate. In addition, the base plate or the material of the base plate can absorb moisture to the required extent without swelling.

[0043] The pressed multi-layer body is then removed from the press and assembled into individual, smaller, panel-shaped components. These are profiled along their side edges and provided with fasteners. These fasteners can be designed as tongue and groove joints. The side edges are preferably provided with a click connection. Furthermore, the floor elements can be provided with a bevel along their upper edges.

[0044] The pressing pressure when pressing the multilayer body is greater than or equal to (≥) 1,000 kPa (kilopascals), preferably greater than or equal to (≥) 3,500 kPa, in particular approximately 4,000 kPa. Since the carrier plate is very densely compacted, a high pressing pressure is advantageous. The pressing temperature is greater than or equal to (≥) 100°C, in particular greater than or equal to (≥) 120°C. The pressing temperature is preferably between 180°C and 210°C. The pressing time is less than or equal to 120 seconds, preferably between 10 seconds and 60 seconds.

[0045] During the pressing process, the surface of the decorative layer can be given a texture or pattern using a textured sheet or other type of texturer. The texture options are extremely diverse. Textures are also conceivable in which the texture runs synchronously with the decor. The texture can vary in gloss in certain areas. Furthermore, various texture depths are possible.

[0046] The top layer has a visible or upper surface structure with a structure depth of, in particular, greater than 80 µm. In particular, the decorative layer acquires its final appearance when the carrier plate and decorative layer are pressed together, meaning the upper surface or visible side of the decorative layer is surface-finished. In principle, no sealing or similar subsequent coating or treatment is required.

[0047] A major advantage of the plate-shaped component according to the invention is that it already has a ready-to-use surface after pressing, meaning that it basically no longer needs to be polished, painted or otherwise treated.

[0048] The invention is described below with reference to exemplary embodiments illustrated in the drawings. In the drawings: Fig. 1a) and b) a first embodiment of a plate-shaped structural element according to the invention in the form of a floor panel; Fig. 2a) and b) a second embodiment of a plate-shaped structural element according to the invention in the form of a floor panel; Fig. 3a) and b) a third embodiment of a plate-shaped component according to the invention in the form of a floor panel and Fig. 4a) and b) a fourth embodiment of a plate-shaped structural element according to the invention in the form of a floor panel.

[0049] Corresponding components or component parts are shown in the Fig. 1 to 4 are provided with the same reference numerals. Fig. Figures 1 to 4 are technically schematic and not to scale.

[0050] The Fig. 1a) and b) and the Fig. 2a) and b) each show an embodiment of a floor panel 1 and 2 according to the invention. Each floor panel 1, 2 comprises a carrier plate 3 and a decorative layer 4 arranged above the carrier plate 3.

[0051] The carrier plate 3 consists of compacted rock wool. To produce the carrier plate 3, rock wool is pressed with thermosetting synthetic binders and highly compressed. The thickness d of the carrier plate 3 is between 5 mm and 12 mm, in particular, the thickness is between 5 mm and 8 mm.

[0052] The decorative layer 4 is formed from bound powder. The powder comprises biomaterial particles, in particular wood particles, in a proportion of between 30% and 70%. Furthermore, the powder mixture contains color pigments, corundum, and resins, in particular thermosetting resins, preferably urea resins or melamine in powder form. The powder can also originate from the production of the carrier plate 3 or its mechanical processing. This is therefore stone flour or stone powder or rock wool powder or dust. Mineral natural stone components are also possible and well-suited as powders, for example, powders based on mica, granite, dolomite, or the like.

[0053] The carrier plate 3 and the decorative layer 4 are pressed together. This occurs under pressure and heat.

[0054] The carrier plate 3, made of highly compressed, pressed rock wool, is non-combustible, or at least flame-retardant. Furthermore, it exhibits heat-insulating and sound-absorbing properties. In particular, the carrier plate 3 has a density of greater than or equal to 800 kg / m3, and in particular, the density is between 800 kg / m3 and 1,500 kg / m3. Preferably, the carrier plate 3 has a density of 900 kg / m3 to 1,400 kg / m3.

[0055] Furthermore, the carrier plate 3 is characterized by its transverse tensile strength. The transverse tensile strength is greater than or equal to (≥) 2.5 N / mm2. In particular, the transverse tensile strength lies between 2.5 N / mm2 and 6 N / mm2. A carrier plate with a transverse tensile strength of 3.5 N / mm2 to 5.0 N / mm2 is considered particularly advantageous.

[0056] Another characteristic of the carrier board 3 is its low moisture absorption capacity, which is less than or equal to (≤) 5%, based on the dry initial weight of the carrier board. In particular, the moisture absorption capacity ranges between 1.0% and 3.0%.

[0057] As in the Fig. 1 and Fig. 2, the side edges 5, 6 of the floor panel 1, 2 are profiled and provided with locking devices 7, 8. The Fig. 1a) and Fig. 2a) show the side edges 5, 6 of a floor panel 1, 2, whereas the Fig. 1b) and Fig. 2b) each show a section of two interconnected floor panels 1, 2, in which the locking means 7, 8 are in mutual engagement.

[0058] The profiling is formed on the support plate 3 and, on the floor panel 1, 2, comprises strip-like locking means 7, 8. For this purpose, the locking means 7 with a continuous coupling groove 9 and a locking tongue 10 projecting on the floor side are provided on the first side edge 5. A continuous, nose-like rib 11 is formed at the free end of the locking tongue 10. At the opposite second side edge 6, the locking means 8 is formed by a projecting coupling spring 12. A locking groove 13 is provided underside of the coupling spring 12. The contours of the coupling groove 9 and the coupling spring 12 are matched to one another in such a way that, when the floor panel 1, 2 is laid, they engage with adjacent floor panels 1, 2 in a floor covering. The coupling springs 12 engage in the coupling grooves 9.In this way, the floor panel 1, 2 can be joined along its side edges 5, 6 without gaps and without glue, in a tensile and compressive manner.

[0059] For floor panel 2, as shown in the Fig. 2, a locking spring 14 is additionally provided. The locking spring 14 is incorporated into a groove 15 in the side edge 6. It is understood that the groove 15 with the spring 14 can also be arranged in the opposite side edge 5. During or after the connection of two adjacent floor panels 2, the locking springs 14 are displaced, either independently or externally, into a corresponding groove 16 provided on the respective opposite side edge 7. The locking springs 14 additionally secure the connection, particularly in the vertical direction.

[0060] Both the floor panel 1 and the floor panel 2 have a counter-layer 17 on the underside of the carrier plate 3. The counter-layer 17 can consist of a counter-layer layer. The counter-layer 17 is preferably constructed similarly to the decorative layer 4 and is formed from a bonded powder.

[0061] To produce a floor panel 1, 2, a multi-layer body is formed. For this purpose, a large-format starting carrier plate made of compacted rock wool is provided. At least one layer of powder is applied to the top side of the starting carrier plate. The powder is a mixture of biomaterial particles, color pigments, corundum, and resins in powder form. The mixture is free-flowing or scatterable. A counter-layer is applied to the underside of the starting carrier plate. This has a similar structure to the decorative layer and is therefore also made of powder. The multi-layer body is then hot-pressed in a press, and the cover layer 4 is firmly bonded to the starting carrier plate. The counter-layer 17 is also firmly bonded to the starting carrier plate. During hot-pressing, the decorative layer 4, like the counter-layer 14, is formed by plasticizing and hardening of the powder mixture.

[0062] The pressed multilayer body is removed from the press and, after cooling, separated into individual panels 1, 2. In a further processing step, the panels 1, 2 are profiled at their side edges 5, 6 and provided with the locking elements 7, 8.

[0063] The installation properties of the described floor panels 1 and 2 can be improved by a lubricant applied to the side edges 5, 6, particularly in the area of ​​the locking means 7, 8. The lubricant can be applied, for example, in liquid form. A sealant is applied to the side edges 5, 6 of the carrier panel 3, preferably in the area of ​​the locking means 7, 8, to improve the water or moisture permeability of an installed floor covering.

[0064] In addition, the side edges 5, 6 of the carrier plate 3 in the area of ​​the locking means 7, 8 are geometrically designed in such a way that the passage of liquid is prevented.

[0065] Furthermore, the underside 18 of the carrier plate 3 or the floor panel 1, 2 can be provided with a profile not shown here. The profile of the underside 18 is such that an adhesive connection of the floor panels 1, 2 to a substrate is promoted using suitable adhesive systems.

[0066] The Fig. 3a) and b) and the Fig. 4a) and b) show an embodiment of a floor panel 19, 20 according to the invention, which corresponds in basic structure to the floor panel 1, as can be seen from the Fig. 1a) and b). Both the floor panel 19 and the floor panel 20 comprise a carrier plate 3 and a decorative layer 4 provided on the upper side. The carrier plate 3 consists of compacted rock wool with the mechanical properties and material properties as previously described. In this respect, reference can be made to the explanations for Fig. 1a) and b).

[0067] In the plate-shaped component in the form of the floor panel 19 according to the embodiment of the Fig. 3a) and b), a flat substrate 21, namely a resin-impregnated carrier substrate, is inserted between the carrier plate 3 and the decorative layer 4. The flat substrate 21 can be formed by a paper layer or a nonwoven layer.

[0068] Furthermore, a flat substrate 22 in the form of a melamine-resin film made of a special cellulose or a counter-pull paper is incorporated below the carrier plate 3 between the carrier plate 3 and the counter-pull 17 formed from the powder mixture.

[0069] In the floor panel 20 in the embodiment of the Fig. 4a) and b), the decorative layer 4 is formed from two layers 23, 24 of a powder mixture. The composition of the powder mixture in the two layers 23 and 24 differs from one another; in particular, the resin or resin content in the two layers 23, 24 differs from one another.

[0070] In a similar manner, the counter-pull 17 can also be constructed from two layers 25, 26 of a powder mixture.

[0071] During the production of the floor panel 20, the individual layers 23, 24 and 25, 26 are pressed together with the carrier plate 3 under pressure and temperature influences.
