Description

[0001] The invention relates to a floor panel and a method for producing such a thin floor panel, which is intended for flat installation.

[0002] A wide variety of floor coverings are known from the state of the art. Flooring in which wooden strips are laid abutting against each other as parquet is widespread. A generally more cost-effective option is laminate flooring, which is made from panels with a melamine resin coating on one side. Melamine resin offers high scratch resistance. Such laminate floors are usually installed floating. They often have profiled end edges so that the individual panels can be connected to one another in a form-fitting manner. Such laminates are referred to in the state of the art as so-called click laminates or panels with a click profile. The carrier boards of such laminate profiles are usually high-density fiberboard (HDF boards) with a board thickness of six millimeters or more. Panels are available on the market that have, for example, 12 mm or 14 mm board thickness.Alternative floor coverings, which also feature a smooth or textured surface, include PVC flooring made of polyvinyl chloride. This plastic requires the addition of plasticizers, otherwise it becomes brittle and fragile. Some plasticizers are environmentally questionable.

[0003] The invention is based on the idea of ​​creating a new type of hard-wearing floor covering that is as resource-efficient as possible.

[0004] The object is achieved according to the invention by a floor panel having the features of patent claim 1 and a method for producing such floor panels having the features of patent claim 12. Advantageous embodiments of the invention emerge from the subclaims.

[0005] The invention is based on the idea of ​​creating a floor covering composed of panels that are laid flat and abutting against one another. The base material is a wood or natural fiber-based core board with a thickness of 1 mm to a maximum of 3 mm. This achieves enormous resource savings compared to previously known laminate flooring. Furthermore, glued installation is preferred, thus eliminating the need for complex profiling on the end edges, as required for laminate flooring, especially click laminates. Furthermore, this makes it possible to significantly reduce the material thickness of the core board.To produce such a thin floor panel, the following steps are required: providing a core board made of a wood or natural fiber material with a top side and an opposite bottom side, applying a top-side coating to the top of the core board, with the core board being provided with a board thickness between 1 mm and 3 mm. The result is a product that requires significantly fewer resources, especially for the core boards. Furthermore, the transport costs are also considerable due to the smaller volume and weight. This also significantly reduces resource consumption.

[0006] The top coating typically comprises a decorative layer, which includes a decorative print applied to a layer of paper or plastic film. This allows any desired decor to be created for the floor. In an alternative design, the print is applied directly to the carrier board.

[0007] Digital printing is particularly preferred, as it allows for the production of customized panels. This avoids panels with identical appearances, especially when installing over large areas, thus further enhancing the impression of a natural material.

[0008] To achieve high wear resistance, preferred embodiments provide for the top coating to comprise a wear layer made of polyurethane or a combination of polyurethane with other plastics. Polyurethane has proven to be a material with very high wear resistance. Furthermore, it can be produced as an elastic layer, which is suitable for the tactile feel of a floor covering. Furthermore, it is possible to coat even thin wood-based or natural fiber panels with a wear layer made of polyurethane. However, this is impossible or very difficult to achieve with the melamine resins commonly used for laminates.

[0009] In one embodiment, the polyurethane wear layer is applied using a spatula. This spatula is preferably heated. The polyurethane layer seals the surface against moisture and other contaminants.

[0010] Alternatively, the polyurethane layer can be applied or pressed onto the carrier board as a separate layer or as part of a finished top coating. In this case, such a layer is glued to the carrier board.

[0011] To prevent deformation of the carrier plate during the manufacturing process and / or to additionally seal the carrier plate from the underside of the carrier plate, a support layer is laminated to the underside of the carrier plate in preferred embodiments. The support layer is preferably made of impregnated paper. However, other impregnated or waterproof films can also be laminated as the support layer.

[0012] If the surface is largely stress-free or if the carrier boards are directly printed, it may also be sufficient to apply a layer of varnish or plastic to the back.

[0013] Although polyurethane is highly resistant to wear, it is somewhat susceptible to scratching. To protect the floor panel against scratches, one embodiment provides for one or more coats of varnish to be applied to the top surface of the floor panel as the outermost layer or layers. A varnish layer for scratch protection can thus be formed as the outermost layer of the top surface coating.

[0014] In order to harmonize the look of the decor with its feel, some embodiments provide for an embossing to be introduced into the upper side of the floor panel. This creates a surface structuring that leads to a surface relief. This means that an upper side of the panel has a different distance from the upper side of the carrier plate at different positions across the surface of the panel. To create such a surface structuring, one embodiment provides for the one or more lacquer layers to be gelled, then a surface structuring is embossed into the one or more lacquer layers, and the one or more lacquer layers are subsequently cured.

[0015] The curing of the one or more lacquer layers is preferably carried out using UV radiation. This causes crosslinking to form polymers in the lacquer layer. However, crosslinking and polymerization are not fully completed. The lacquer is only fully crosslinked and / or polymerized after embossing. Curing can also be carried out using UV radiation or electron beam curing (EBC). This allows very strong and scratch-resistant lacquer layers to be created. Embossing is preferably carried out using an embossing calender. However, other embossing tools can also be used.

[0016] In another variant, the top layer of the lacquer is treated with an excimer before gelling. In a nitrogen-inertized room, the excimer radiation folds the top layer, similar to the formation of a skin on warmed milk. The excimer treatment creates an initial fine relief on the lacquer surface, which visually results in a matting finish with a very low gloss level. This surface is then gelled, and a second, much deeper relief is embossed into the first relief. The second embossing can also partially alter the first relief, creating a very vibrant surface. This makes it possible to create different gloss levels.

[0017] One embodiment provides for matting by means of an excimer treatment, with the excimer treatment being carried out before any gelling. The top layer of lacquer then has a surface structure created by the excimer treatment.

[0018] During production, polyurethane plastic, preferably in a hot or heated state, is applied with a spatula. The lacquer is then applied to the polyurethane plastic before it has reached a high degree of curing, meaning it is still malleable. This lacquer is then embossed together with the polyurethane. If a matting finish is desired, the lacquer is excimer treated before embossing. The embossing process following matting alters the matting in some places. Finally, the material is fully cured, preferably using electron beams.

[0019] The one or more lacquer layers can also be laminated onto the finished surface coating. This allows the surface coating to be produced separately from the final production of the floor panels.

[0020] The top coating can be laminated to the carrier board as a fully impregnated and printed film, preferably including one or more lacquer layers, which may also be embossed. This means that only a single step is required during final production to apply the entire top coating to the carrier board.

[0021] Typically, production is carried out using carrier boards with a surface area larger than the floor panels being manufactured. Therefore, a finishing process is carried out during production, in which the carrier board, to which the surface coating is completely or at least almost completely applied, is divided, i.e., the floor panels are separated from the semi-finished product.

[0022] To prevent damage to the panels during use, the end edges must be sealed. In one design, the floor panels are provided with V-shaped joints on one or more end faces. Such a V-shaped joint is then sealed with a waterproofing joint sealant.

[0023] In one embodiment, surfaces of one or more front edges running perpendicular to the top side are sealed with a polyurethane layer.

[0024] Particularly preferred for sealing the at least one end face or end edge, preferably at least two opposite end faces and particularly preferably all end faces, is by pulling the top side coating over the end face or end faces. In this way, the at least one end face is sealed by pulling the top side coating over the end face. This can be done, for example, by so-called postforming, in which, after the top side coating has been applied, parts of the carrier plate are milled off from the underside at the end face and then the protruding top side coating is pulled over the end face formed by milling and glued to it. This can be done on multiple end faces.

[0025] In a particularly preferred embodiment, the top coating is extended over at least one of the end faces to the underside of the floor panel. This ensures optimal sealing of the end face. Moisture penetrating any installation joints cannot directly reach the panel's base plate.

[0026] If the underside is also provided with an impregnated underlay, an overlapping seal on the underside can also be achieved.

[0027] In an alternative embodiment, the end faces are preformed prior to the application of the top layer, and the top coating is pulled directly over at least one end face, preferably the two opposite end faces, or particularly preferably over all end faces. Again, it is particularly preferred to pull the top coating over at least one end face, preferably two opposite end faces, and particularly preferably all end faces, down to the underside of the panel.

[0028] The top coating, which extends down to the underside, can be partially or fully bonded to the surface adjacent to the underside.

[0029] For straight edges, impregnation and hydrophobization can alternatively be carried out, although the installation of such panels is only suitable on perfectly flat surfaces, as otherwise moisture damage can occur in the gaps in the joints.

[0030] Since there are no profiles on the end faces for positive fastening, the floor panels are particularly suitable for adhesive installation. Therefore, one design provides for a permanently elastic adhesive layer to be applied to the underside of the floor panel. Such a panel, with a permanently elastic adhesive layer applied to the underside, can be laid directly on a floor. This simplifies the installation steps. Furthermore, it ensures that an optimal amount of adhesive is used and not too much glue is used to bond the panels. This also ensures optimal use of resources from an ecological perspective.

[0031] To prevent the permanently elastic adhesive from sticking to the panels during transport due to excessive pressure, a preferred embodiment provides for the permanently elastic adhesive layer to be covered with a removable protective film. This is removed from the permanently elastic adhesive layer before installation.

[0032] If desired, one embodiment allows for impact sound insulation to be inserted between the carrier board and the permanently elastic adhesive. A cork layer or other impact sound insulation layer, for example, is suitable for this. In one embodiment, a cork or impact sound insulation layer is applied before or at the same time as the permanently elastic adhesive layer is applied, and is positioned between the underside of the carrier board and the permanently elastic adhesive layer.

[0033] The protective layer and adhesive, as well as a cork layer or other impact sound insulation layer, can be laminated to the underside of the panel in a single step. In an alternative embodiment, the cork layer and / or the adhesive layer are applied separately to the underside with a squeegee or spatula.

[0034] The invention is explained in more detail below with reference to a drawing. Herein: Fig. 1 a perspective schematic view of a panel; Fig. 2 a cross-sectional view through a panel; Fig. 3 a longitudinal section view of a panel; and Fig. 4 a schematic representation of a flow diagram of a method for manufacturing a panel.

[0035] In Fig. Figure 1 shows a schematic sectional view of a floor panel 1. The dimensions of the individual layers and elements shown are not drawn to scale, but are partly enlarged or reduced in size relative to other elements to illustrate the invention.

[0036] The same technical features are identified by the same reference numerals in all figures.

[0037] In Fig. 1 shows a schematic perspective view of a floor panel 1. A top side 2 has a top coating 30, which in the illustrated embodiment is drawn over rounded end faces 14, 15, which are opposite one another. The surface coating 30 is drawn over the end face 14 to a bottom side 3 and is bonded partially or completely to the bottom side 3. In the case of the end face 15, the end face is only partially rounded and the top coating 30 is drawn only to the bottom side 12 of the carrier plate 10. In both cases, the end faces 14 and 15 are sealed by the top coating 30. The two other end faces 17 and 18 and their sealing will be described later in connection with Fig. 3 is explained in more detail.

[0038] Fig. 2 shows the sectional view AA (a cross section), the Fig. 3 the sectional view BB (a longitudinal section) according to Fig. 1. The floor panel 1 comprises a carrier board 10. This has a top side 11 and an opposite bottom side 12. These are oriented plane-parallel to one another. A layer thickness 13, measured perpendicular to the top side 11 and the bottom side 12, has a value between 1 mm and 3 mm. The carrier board 10 is preferably made of a wood-based material or a natural fiber material. For example, it can be an HDF board (HDF board - High Density Fiberboard), a thin chipboard, or a similar carrier board. It is preferably a board made of a wood-based material or a natural fiber material, such as bast, hemp, wood, cellulose, or similar fibers or fiber mixtures.

[0039] A preferably impregnated underlay, for example, a thin impregnated paper layer, is applied to the underside 12 of the carrier plate 10. This prevents deformation of the carrier plate due to residual moisture in the carrier plate material when coating the top side, particularly when using adhesives that require a higher temperature for processing. Alternatively, a sealant made of polyurethane, varnish, adhesive, or other plastic can be applied in a stress-free construction.

[0040] The top coating 30 is applied to the top side 11 of the carrier plate 10. In the illustrated embodiment, this comprises an impregnated paper layer 21 or thin plastic film onto which the decoration 22 is printed. In alternative embodiments, the decoration can also be printed directly onto the top side 11 of the carrier plate 10. Any known printing method can be used to create the print. Preference is given to gravure and offset printing methods or digital printing methods, such as inkjet printing. This allows for individual design of the individually produced panels. In one embodiment, the impregnated and printed paper layer 21 or thin film is laminated onto the top side 11 of the carrier plate 10.

[0041] The top coating 30 further comprises a wear layer 24. This is preferably made of polyurethane. In one embodiment, the polyurethane is applied by troweling to the top of the carrier plate, preferably after it has been printed or after the thin paper layer 21 or thin foil provided with the decorative print has been laminated onto it.

[0042] Since polyurethane is highly durable but not particularly scratch-resistant, one or more lacquer layers 26 are preferably provided as the outermost layer(s). Furthermore, it is possible to emboss a height structure into the lacquer layers. To create this structure, the lacquer layer is applied and first cured using UV radiation. Alternatively, the lacquer layer can be matted using an excimer before curing. Depressions 27 are then embossed into the cured lacquer layer(s). This is preferably done using an embossing calender. However, other methods and tools can also be used to create the surface embossing. The lacquer layer is then fully cured. This is done, for example, using UV radiation or electron beams.Embossing is preferably carried out in such a way that the structure corresponds in position and / or extent to the printed decor. This allows, for example, knotholes in wood decors to be realistically reproduced.

[0043] In the illustrated embodiment, the end face 14 is completely rounded, and the opposite end face 15 is rounded at least at the edge toward the top side 11 of the carrier plate 10. As already described above, the top side coating 30 is drawn over the end faces 14 and 15. This can be done either with an immediate forming step if the end faces are already preformed before the application of the top side coating 30. The forming preferably takes place via one or more milling processes.

[0044] Alternatively, the top coating 30 can be applied to a carrier plate 10 whose dimensions are larger than those of the individual panels. Then, before sealing the end faces 14, 15, 16, 17, the panels are assembled from the coated carrier plate.

[0045] The two longitudinal end faces 14 and 15 are then sealed, for example, using a so-called post-forming process. In this process, the end faces are milled out from the underside 12 in order to round the end faces 14 and 15. An overhang of the surface coating 30 remains. This overhang is then pulled over the end faces and glued to them. While in the case of the end face 15 that is only rounded to the top side 11, the top side coating 30 is only pulled as far as the underside 12 of the carrier plate, in the case of the fully rounded end face 14, the top side coating 30 is pulled over the end face 14 as far as the underside 12 of the carrier plate and is glued there piece by piece or over the entire surface to the underside. This achieves optimal sealing of the end face 14.In this embodiment, in addition to the joist 20, a cork impact sound insulation layer 42, a permanently elastic adhesive layer 44, and a protective layer 46 are applied to the underside 2 of the panel 1. The cork layer 42 and the adhesive layer 44 can each be laminated, squeegeed, or troweled on separately. Alternatively, they can also be bonded together with the protective layer 36 as a composite to the underside 12 of the carrier board 10 or the joist 20. The impact sound insulation layer can also replace the joist.

[0046] In this case, the cork layer or any other impact sound insulation layer can also be omitted, and the adhesive layer 44 can be bonded directly to the underside 12 of the carrier board 10 or the joist 20 using the permanently elastic adhesive. The protective layer 46 is removed before installation and serves only to protect the adhesive layer 44 during transport and storage.

[0047] In Fig. Figure 3 shows a longitudinal section through a panel 1, with the central section cut out. The end face 16 is provided with a bevel 19 to form a V-shaped joint 50. This V-shaped joint 50 is sealed with a joint sealant 52. The remaining portion of the end face, as well as the end face 17, are provided with a sealant and hydrophobic coating, which is particularly made from a polyurethane base. These layers are designated 60 and 61.

[0048] Based on Fig.4, a manufacturing method 1000 of such a floor panel 1 is briefly explained again by way of example. First, a carrier plate is provided 100. In some embodiments, the end faces of the carrier plate are machined 110. Furthermore, it is advantageous to attach a support beam 120 to the underside of the carrier plate, which preferably consists of an impregnated paper or an impregnated thin plastic film. In order to apply a decoration 130 to the upper side, in one embodiment, a paper or film is impregnated 140 and then printed 150 with the decoration. In alternative embodiments, the decoration can also be printed directly onto the upper side of the carrier plate.

[0049] Furthermore, a wear layer of polyurethane is formed 160. As scratch protection, one or more layers of varnish are applied as outermost layers of the surface coating.

[0050] In some embodiments, surface structuring is carried out 170. For this purpose, the topmost lacquer layer or several of the lacquer layers are preferably cured with UV radiation 180. The lacquer layer can be matted with an excimer before curing. A surface structure is then embossed 190 into the cured lacquer layer or layers. This is preferably done with an embossing calender 200. The one or more lacquer layers are then completely cured 210. This is done, for example, with UV radiation or by means of electron beam curing (EBC). The individual layers described so far can be individually laminated or applied with a spatula or applied, or laminated as a finished top surface coating 220. The top surface coating is often applied to a carrier plate whose lateral dimensions are larger than those of an individual floor panel.Therefore, it is preferable to assemble the floor panel, i.e. the carrier plate provided with the top coating, into several panels 250.

[0051] The end faces are then sealed 260. Alternative methods exist for this. For example, a V-shaped joint can be created on the end face 270, which is then sealed with a joint sealant 280.

[0052] Vertical surfaces of the end faces can, for example, be sealed with polyurethane and made hydrophobic 290. However, floor panels sealed in this way are generally only suitable for installation on flat surfaces.

[0053] The end faces are preferably sealed by pulling the top coating over the end faces 300. This can be done, for example, by postforming 310. If the end faces are already rounded and pretreated, direct forming 320 can also be performed when laminating the top coating. Pulling over an end edge can be done adjacent to the underside or over the underside, so that the top coating is bonded to the underside of the carrier plate over part or all of its surface.

[0054] A sound-absorbing layer can be applied to the underside of the carrier board. 330 This layer, for example, is formed as a cork layer. This layer can be applied with a filler or laminated as a finished layer. The sound-absorbing layer can also be omitted in certain designs.

[0055] A finished floor panel preferably has a permanently elastic adhesive layer that is applied to the impact sound insulation layer or the underside of the carrier board, optionally its underlay 340. The permanently elastic adhesive layer can be applied by troweling, doctoring, or even laminating a thin adhesive layer. This is preferably done together with a protective layer, which is applied 350. The protective layer can also be applied individually, provided the adhesive layer has been applied previously. The impact sound insulation layer, the adhesive layer, and the protective layer can also all be applied together to the underside of the carrier board or its underlay.

[0056] It will be apparent to those skilled in the art that individual steps of the described method, in particular those describing alternative or optimal steps, can be omitted or even carried out in a modified sequence. The features and method steps described here can be carried out in any combination to implement the invention and create a thin floor panel with a carrier layer made of a wood or natural fiber material, which preferably has a wear-resistant polyurethane layer with a varnish layer applied thereover as scratch protection and a permanently elastic adhesive layer for bonding the floor panel. The impact sound insulation layer and the adhesive layer as well as the protective layer can also be omitted in some embodiments, so that the panel is bonded during installation with adhesive applied directly to the floor.
