Description

[0001] Embossed structure

[0002] Description

[0003] 1. Technical area

[0004] The present invention relates to a wall, ceiling, furniture, or floor panel, wherein the panel has an embossed structure and a lacquer layer thereon. The present invention further relates to a method for producing such a panel.

[0005] 2. State of the art

[0006] There are a variety of different panels, such as wall, ceiling, furniture, and floor panels. Furthermore, there is a wide range of manufacturing processes for panels.

[0007] There is currently a constant need to improve the properties of panels and / or the corresponding manufacturing processes for such panels. In particular, it is of interest to improve a variety of different panel properties. These properties include, for example, environmental friendliness, such as recyclability, haptic properties, appearance, and / or durability, such as fire, moisture, and / or scratch resistance.

[0008] Particularly in the technical area of ​​flooring panels (e.g., in the "floor factory" sector), it is of interest to design the surfaces, especially the visible surfaces of the panels, in a visually and tactilely appealing manner. For this purpose, surface textures are used, for example. Likewise, the manufacturing processes should be geared toward visually appealing panels, panels with an improved tactile appearance, and panels that are also durable.

[0009] Well-known panels in such a technical field for visible surfaces include laminate panels, which are cost-effective and easy to handle. They typically comprise a core made of medium-density fiberboard (MDF) or high-density fiberboard (HDF), which allows for thermal recycling.

[0010] In the prior art, known panels, for example, feature lacquer structures that are applied using a textured lacquer application roller. This lacquer application occurs after a coating, for example, with a decorative layer. Thus, a structure is applied to the surface of the finished panel using a lacquer layer, creating a raised structure.

[0011] The state of the art has several disadvantages. For example, only raised structures can be created. This results in an increased demand for paint to create the structures. Depending on demand and customer requirements, large quantities of paint may be required, which increases costs. Furthermore, with certain manufacturing processes, the application quantity of paint must be locally adjusted to create the desired structures. A further disadvantage of known approaches in the state of the art is that the sequence of the work steps reduces the flexibility of the panel's visual design.

[0012] In view of the above disadvantages, there is an increased need to provide improved panels and improved manufacturing processes for these panels.

[0013] Thus, it is an object of the present invention to at least partially overcome the above-mentioned disadvantages. In particular, it is an object of the present invention to provide a panel that has improved optical and haptic properties. Furthermore, a corresponding manufacturing method for the panel is to be provided. Summary of the Invention

[0014] The objects are at least partially achieved by a panel and a method for producing a panel, as defined in the independent claims. Further aspects of the present disclosure are defined in the dependent claims. Since the panel and the method for producing a panel both relate to panels, it is understood that advantages and / or features of the panel may also apply to the method and vice versa. In particular, the object is achieved by a panel, in particular a wall, ceiling, furniture, or floor panel, wherein the panel comprises:

[0015] - a carrier board, such as a medium-density fiberboard (MDF), a high-density fiberboard (HDF), or a particle board; wherein the board has an embossed structure on its main surface, wherein the embossed structure comprises one or more three-dimensional structures extending at least partially into the board; and

[0016] - at least one layer of varnish applied to the embossed structure.

[0017] This has the advantage that the carrier plate is provided with an embossed structure, which has a lacquer layer on top. This makes it easier to incorporate the structure into the carrier plate itself. This eliminates the need to apply different lacquer layer thicknesses to create structures.

[0018] Another advantage is that the structures are embossed, extending into the panel. This eliminates the need to create raised areas for a structure. This can be advantageous, for example, if objects are to be placed on the panel. This reduces unevenness caused by different elevations. It can also offer advantages in terms of haptic properties, as the panel feels more even.

[0019] The lacquer layer is applied to the embossed structure. With regard to the chronological sequence in the manufacture of the panel, this should be understood to mean that the lacquer layer is applied after embossing. The lacquer layer can therefore advantageously be designed to serve its purpose: the lacquer layer can thus provide sufficient elasticity to compensate for deformation of the panel. It may also be possible to apply a lacquer layer based on a harder, i.e., less elastic, material. This can achieve greater resistance to impacts, scratches, and / or chemicals. Suitable lacquer layers that can be used herein include, but are not limited to, corundum particles, acrylate, polymers, oligomers, additives, and / or the like. Furthermore, the lacquer layer can be applied by means of flexography or any other type of application technique.Therefore, the lacquer layer is not necessarily to be understood as a layer of laughter with which elevations are created.

[0020] The lacquer layer is applied 'on' the embossed structure, which means that a further layer (such as a decorative layer) can be placed between the lacquer layer and the plate.

[0021] Overall, the arrangement contributes to improved optics and the manufacturing process can be simplified and carried out cost-effectively.

[0022] The core board (also referred to herein as "board" for brevity) can be a board made of a wood-based material, such as medium-density fiberboard, high-density fiberboard, particle board, oriented strand board, or similar. However, it can also be made of a plastic material, such as luxury vinyl tile (LVT), a rigid polymer core, or an expanded polymer core, as well as mixed constructions widely used in the flooring industry. High-density fiberboard (HDF) allows for good recyclability.

[0023] The term “three-dimensional” is to be understood in the context of the embossed structure of the present disclosure in such a way that the embossed structure has an extension at least recognizably in three spatial directions.

[0024] Preferably, the one or more three-dimensional structures extend into the plate by at least 0.02 mm, preferably at least 0.03 mm, more preferably at least 0.04 mm, most preferably at least 0.05 mm. Alternatively or additionally, the one or more three-dimensional structures extend into the plate by at most 3.0 mm, preferably at most 2.5 mm, more preferably at most 2.0 mm, more preferably at most 1.8 mm, most preferably at most 1.5 mm.

[0025] This has the advantage that the three-dimensional structures are visible, thus providing a correspondingly improved appearance. For example, the three-dimensional structures could serve to reinforce and / or imitate a pattern of a decorative print layer.

[0026] On the one hand, the extension of the three-dimensional structures into the panel has proven to be small enough so that the panel does not experience excessive mechanical weakening. Consequently, the panels' high robustness and a wide range of applications are ensured. On the other hand, the extension of the three-dimensional structures into the panel has proven to be large enough to ensure a sufficient improvement in the optical and haptic properties. In this way, the inventors have succeeded in identifying a sufficient compromise in the extension, whereby the opposing objectives can be duly taken into account.

[0027] Preferably, the one or more three-dimensional structures cover at least 0.5%, preferably at least 1%, more preferably at least 2%, more preferably at least 3%, more preferably at least 4%, more preferably at least 5%, more preferably at least 6%, more preferably at least 7%, most preferably at least 8% of the main area. In other examples, it may also cover at least 9%, 10%. Alternatively or additionally, the one or more three-dimensional structures cover at most 95%, preferably at most 90%, more preferably at most 80%, more preferably at most 60%, more preferably at most 50%, more preferably at most 40%, more preferably at most 30%, more preferably at most 20%, most preferably at most 10% of the main area.

[0028] This offers the advantage that one or more three-dimensional structures are recognizable and thus contribute to improving the optical and haptic properties.

[0029] The coverage of the skin surface specified here has proven sufficient to improve the optical and haptic properties (high coverage is desirable), while at the same time not significantly affecting the mechanical properties of the carrier plate (low coverage is desirable). This allows a reasonable compromise in coverage to be achieved.

[0030] In one embodiment of the panel, the one or more three-dimensional structures are arranged on one or more first regions of the main surface, wherein the main surface has a second region without three-dimensional structures.

[0031] One or more first regions may be provided. If multiple first regions are provided, a three-dimensional structure is typically arranged in each first region. A three-dimensional structure can have different extensions into the plate. If the extensions are visible, this is usually referred to as a first region. If the extension is negligible at one point on the main surface and appears larger immediately adjacent to this point, this can be referred to as a further three-dimensional structure and consequently as a further first region.

[0032] The areas in which no three-dimensional structures are recognizable to the skilled person without any aids are referred to herein as the second area. The skilled person is capable of making such a distinction.

[0033] Preferably, a periphery of one or more of the first regions of the main surface has the lacquer layer applied thereto at least 10%, preferably at least 20%, more preferably at least 30%, most preferably at least 50% of an average thickness of the lacquer layer.

[0034] This has the advantage of ensuring a sufficient coating thickness is applied to the perimeter of the one or more first regions. The perimeter of the first region or the perimeters of the multiple first regions may, for example, be exposed to higher mechanical stresses. Thus, a sufficient coating thickness promotes the longevity of the panel.

[0035] The perimeter of the first region or the perimeters of the plurality of first regions can be understood as the transition from the embossed structure to the main surface of the panel. Thus, the perimeter or perimeters can also be understood as the edge or edges.

[0036] It should be noted that, for example, three-dimensional structures added (accidentally) to the panel after the lacquer layer has been applied can damage the panel. Consequently, this results in the absence of a lacquer layer at the edge described here.

[0037] Preferably, the perimeter of one or more of the first regions of the main surface is composed of a plurality of the following lines: a straight line, a zigzag line, a circular segment line, a rounded segment line, an elliptical segment line, a corner, preferably the perimeter is composed of a plurality of these lines in a random order.

[0038] This offers advantages regarding the design of one or more of the first areas of the main surface, allowing for visual and tactile improvements.

[0039] Preferably, the width of one or more of the first regions of the main surface perpendicular to a longitudinal extent of the plate compared to the width of the plate is at least 0.05%, preferably at least 0.1%, more preferably at least 0.15%, more preferably at least 0.2%, more preferably at least 0.5%, more preferably at least 1.0%, more preferably at least 1.5%, more preferably at least 2.0%, more preferably at least 3.0%, more preferably at least 4.0%, most preferably at least 5.0%.Alternatively or additionally, the width of one or more of the first regions of the main surface perpendicular to a longitudinal extent of the plate compared to the width of the plate is at most 90%, preferably at most 85%, more preferably at most 80%, more preferably at most 70%, more preferably at most 60%, more preferably at most 50%, more preferably at most 45%, more preferably at most 40%, more preferably at most 35%, more preferably at most 30%, more preferably at most 25%, more preferably at most 20%, more preferably at most 15%, most preferably at most 10%.

[0040] These widths have proven sufficient to provide improved visual and haptic quality, while maintaining a high level of robustness and mechanical integrity. Smaller widths can also be advantageous, allowing a larger number of first regions to be arranged on the main surface.

[0041] The plate typically has a longitudinal extension (length) and a width perpendicular to the longitudinal extension. The width of the plate is typically small compared to the length. The width of one or more of the first regions described herein is therefore to be determined along the same direction as the width of the plate. Preferably, a thickness of the plate and the lacquer layer at the first regions is smaller compared to the thickness of the plate and the lacquer layer at the second region.

[0042] This has the advantage that the lacquer layer does not significantly adversely affect the presentation of the three-dimensional structure(s) in the first area(s). Thus, the three-dimensional structures remain visible even when the lacquer layer is present. Consequently, this benefits the optical, tactile, and mechanical properties of the panel.

[0043] The thickness is measured substantially perpendicular to the longitudinal extent and substantially perpendicular to the width of the plate.

[0044] In a further embodiment of the panel, the panel further comprises one of the following layers in the specified order from the main surface and below the lacquer layer:

[0045] - a primer layer; and

[0046] - optionally a decorative print layer.

[0047] The primer layer allows the decorative print layer to be applied with sufficient quality. This improves the application of the decorative print layer. It is understood that the primer layer is applied directly beneath the decorative print layer.

[0048] The decorative print layer is applied in such a way that it can be seen from the top of the panel when the panel is in a typical position, e.g., on a floor, wall, ceiling, or similar. The top / main surface of the panel usually faces a rear surface of the panel. This allows the print layer and its decorative aspect to be more clearly visible.

[0049] The back surface of the panel may be configured to be attached to a base surface, e.g., a wall, ceiling, or floor surface. In one example, the back surface may be provided with adhesives and / or mechanical attachment means. The decorative print layer may comprise a decorative pattern. The decorative pattern may mimic any desired appearance. In one example, the decorative pattern may mimic a natural surface.

[0050] Preferably, the lacquer layer is applied directly above the decorative print layer, wherein optionally the decorative print layer is applied directly above the primer layer, wherein optionally the primer layer is applied directly above the plate and the embossed structure.

[0051] In a further embodiment, the panel further comprises:

[0052] - a wear layer applied directly above the paint layer.

[0053] In one example, the wear layer can be applied by hot-melt lamination or glue lamination. Optionally, the wear layer can be based on cast polypropylene.

[0054] The wear layer has the advantage of further improving the protection of the panel. In particular, the wear layer can protect the decorative print layer.

[0055] The wear layer is applied directly above the paint layer, which means that the wear layer essentially does not contact the plate. Furthermore, "directly above" in one example may be understood to mean that no further layer can be placed between them.

[0056] In one example, the decorative print layer contacts the primer layer, the lacquer layer contacts the decorative print layer, and the wear layer contacts the lacquer layer. This allows the layers to be applied to the panel in the following order, as viewed from the panel: the primer layer, the decorative print layer, the lacquer layer, the wear layer.

[0057] The objects of the present invention are further achieved at least in part by a method for producing a panel, in particular a wall, ceiling, furniture or floor panel, comprising the following steps: IO

[0058] Providing a carrier board, such as a medium density fiberboard (MDF) or a high density fiberboard (HDF) or a particle board;

[0059] - embossing the plate using an embossing structure, such as an embossing roller, to provide the plate with an embossed structure on its major surface, wherein the embossed structure comprises one or more three-dimensional structures extending at least partially into the plate;

[0060] - Applying, after embossing the plate, at least one layer of varnish on the embossed structure.

[0061] It is understood that essentially the same advantages and features mentioned with regard to the panel apply equally to the method for producing a panel. The features can thus also be combined and / or applied interchangeably to embodiments of the panel or the method.

[0062] The method comprises one or more steps of applying layers that do not necessarily need to be bonded during application. Also, in the process for producing a panel, the layers may be at least partially viscous / liquid during the application of the layers.

[0063] Preferably, applying the lacquer layer comprises applying the lacquer layer with a substantially constant thickness.

[0064] This has the advantage that no unnecessary varnish needs to be used to provide structures in the panel.

[0065] Preferably, providing the carrier plate comprises formatting an initial carrier plate into one or more carrier plates.

[0066] An initial (large) carrier plate can thus be formatted into the carrier plate. This makes the plate suitable for direct use in a specific application. This eliminates the need for formatting in a subsequent process step, such as embossing. Further advantages are described herein with respect to the panel. In one example, the plate has a width (w) of at least 4 cm and / or at most 200 cm.

[0067] Preferably, the method further comprises profiling the plate to provide a connecting structure on at least one side surface of the plate, wherein the side surface is substantially perpendicular to the main surface of the plate, preferably directly after embossing the plate.

[0068] The side surface of the panel is essentially perpendicular to the top / main surface of the panel. Profiling allows the panel to be connected to another panel. This can be achieved, for example, by means of a form-fitting connection. The connecting structure allows the side surface to be configured to engage with a side surface of another panel. Profiling can also include providing a connecting structure on both side surfaces.

[0069] Preferably, the method further comprises applying a primer layer to the panel after embossing the panel. Respective advantages are described herein with respect to the panel.

[0070] Preferably, the method further comprises applying, optionally after embossing the panel, a decorative print layer to the panel, further optionally after applying the primer layer, preferably by means of rotogravure printing, flexography, and / or digital printing. Respective advantages are described herein with respect to the panel.

[0071] Preferably, the lacquer layer is applied after the decorative print layer has been applied. Consequently, the lacquer layer is positioned above the decorative print layer. The respective advantages are described herein with reference to the panel.

[0072] Preferably, the method further comprises applying, optionally after applying the lacquer layer, a wear layer to the plate, further optionally applying the wear layer by means of melt lamination or adhesive lamination, wherein the wear layer is optionally based on cast polypropylene. Respective advantages are described herein with respect to the panel. One embodiment relates to the panel and / or the method for producing the panel, wherein the plate has a thickness of at least 1 mm, preferably at least 2 mm, more preferably at least 3 mm, more preferably at least 4 mm, more preferably at least 5 mm, more preferably at least 6 mm, more preferably at least 7 mm, most preferably at least 7.5 mm.Alternatively or additionally, the plate has a thickness of at most 40 mm, preferably at most 35 mm, more preferably at most 30 mm, more preferably at most 25 mm, more preferably at most 20 mm, more preferably at most 18 mm, more preferably at most 14 mm, most preferably at most 10 mm.

[0073] These thicknesses have proven sufficient to provide adequate rigidity and high wear resistance, while keeping material usage at a moderate level.

[0074] A further embodiment relates to the panel and / or the method for producing the panel, wherein the lacquer layer has a thickness of at least 10 μm, preferably at least 20 μm, more preferably at least 30 μm, more preferably at least 50 μm, more preferably at least 60 μm, more preferably at least 70 μm, more preferably at least 80 μm, most preferably at least 90 μm. Alternatively or additionally, the lacquer layer has a thickness of at most 400 μm, preferably at most 300 μm, more preferably at most 200 μm, more preferably at most 150 μm, more preferably at most 120 μm, most preferably at most 110 μm.

[0075] These paint layer thicknesses have proven advantageous in providing a stable, wear-resistant and visually and haptically appealing panel.

[0076] Preferably, the one or more three-dimensional structures on the main surface are arranged to imitate a natural pattern, in particular a wood and / or a stone pattern.

[0077] This contributes to an improved appearance and increases the quality of the corresponding panel. The three-dimensional structures described herein are to be understood as those that have been deliberately and intentionally incorporated into the carrier plate. Those skilled in the art will understand this, in particular, because, for example, a pattern can be reproduced in this way.

[0078] Preferably, the one or more three-dimensional structures do not have a defined geometric shape, such as a triangle, a circle, an ellipse, a rectangle, in particular a parallelogram, a trapezoid.

[0079] The geometric shape described herein can be viewed from above, for example, looking toward the main surface of the panel. This has the advantage of providing a natural and enhanced appearance. However, in some cases, combinations of individual geometric shapes can also result in an undefined geometric shape, which can also be recognized as such.

[0080] Preferably, the one or more three-dimensional structures are arranged unevenly and / or randomly on the main surface.

[0081] This offers advantages in terms of providing the three-dimensional structures and the appearance of the entire panel. The three-dimensional structures described herein can be provided, for example, by an embossing machine with appropriate boards.

[0088] Preferred embodiments are presented below, primarily with reference to the above figures. It should be noted that further embodiments are certainly possible, and the following explanations are to be understood only as examples and not as limitations. Furthermore, the present invention may also be used in other embodiments not explicitly disclosed below. Furthermore, as described in detail below, the embodiments are compatible with one another, and individual features of one embodiment may also be applied to another embodiment.

[0089] It is understood that the dimensions of the figures are merely schematic and therefore not to scale.

[0090] Fig. i shows a schematic cross-section of a panel i according to an embodiment of the present disclosure. The panel 1 can be a wall, ceiling, furniture, or floor panel. The panel i can also be used as a worktop or as a vertical surface, such as in furniture fronts or doors. The panel i comprises a carrier board 10, such as a medium-density fiberboard (MDF), a high-density fiberboard (HDF), or a particle board. The board 10 has an embossed structure n on its main surface 15, wherein the embossed structure 11 comprises one or more three-dimensional structures 11 extending at least partially into the board 10. The panel 1 further comprises at least one lacquer layer 21 applied to the embossed structure 11. In this cross-sectional view, two three-dimensional structures 11 can be seen. These extend into the carrier board 10 by at least 0.02 mm and by at most 3 mm.

[0091] Furthermore, two first regions 12 are identified, wherein the two three-dimensional structures 11 are arranged on the two first regions 12 of the main surface 15. Furthermore, a second region 13 without a three-dimensional structure 11 is shown. The perimeter 14 of the first regions 12 of the main surface 15 has a lacquer layer 21, wherein the thickness of the lacquer layer at the perimeter 14 is at least 10%, 20%, or 30% of an average thickness of the lacquer layer 21. The panel 10 has a rear surface 17. The rear surface 17 typically faces a floor, a wall, a ceiling, or the like, depending on the application area of ​​the panel 1. The main surface 14 is usually visible and opposite the rear surface 17. The panel 10 can also comprise a connecting structure (not shown) on at least one side surface 16 of the panel 10.

[0092] Furthermore, it can be seen that the thickness of the plate 10 and the lacquer layer 21 in the first regions 12 is smaller compared to the thickness of the plate 10 and the lacquer layer 21 in the second region 13.

[0093] Fig. 2 shows the embodiment of Fig. 1 in a plan view. Cross section AA from Fig. 1 is also schematically indicated therein. It can be seen that a plurality of three-dimensional structures 11 (only two are marked) and first regions 12 (only two are marked) are encompassed by the panel 1. The longitudinal extent L and the width w of the panel 1 are also shown.

[0094] In Fig. 2, the three-dimensional structures 11 extend into the image plane. Thus, the extension is, for example, perpendicular to the main surface 15 of the plate 1.

[0095] It can be seen that the perimeter 14 (only one is marked) of the plurality of first regions 12 of the main surface 15 is composed of a plurality of the following lines: a straight line, a zigzag line, a circular segment line, a rounded segment line, an elliptical segment line, a corner.

[0096] Fig. 3 shows a schematic cross-section of a panel 300 according to an embodiment of the present disclosure, wherein additional layers are included. The panel 300 is similar to the panel 1 of the embodiment of Fig. 1 and only the differences will be described. The panel 300 further includes a primer layer 19 applied to the panel 10 directly above the plate 10. A decorative print layer 20 is also shown. The decorative print layer 20 is applied directly above the primer layer 19 (as viewed from the plate 10). The panel 300 further includes a wear layer 22 applied directly above the paint layer 21 (as viewed from the plate 10). The arrangements of the layers and the order are evident from Fig. 3.

[0097] The layers above the decorative print layer 20 are configured so that the decorative print layer 20 can be viewed from above (e.g., in the figure, in a vertical direction from top to bottom). The three-dimensional structures 11 can serve to reinforce and / or imitate a pattern of a decorative print layer.

[0098] It should be emphasized that the relationship of the extension of the three-dimensional structures 11 and the thicknesses of the layers 19, 20, 21 and 22 as well as the thickness of the carrier plate 10 differ from each other in reality and the figure is therefore merely schematic in nature.

[0099] Fig. 4 shows a diagram of an exemplary method 100 according to an embodiment of the present disclosure.

[0100] The method 100 for producing a panel 1, in particular a wall, ceiling, furniture or floor panel, comprises the following steps:
