Description

The present invention relates to a decorative panel and a method for producing a decorative panel. In particular, the invention relates to a decorative panel in which opposite long edges of the panel, at least in sections, do not run parallel to the longitudinal axis. In addition, the present invention relates to a method for producing a decorative panel with the step of dividing a large panel comprising a multiple of the area of a decorative panel into individual decorative panels by means of a cutting means that is freely movable in at least 2 axes.

Decorated panels or decorative panels are known per se and are used, for example, in interior construction as a floor or wall covering. The term wall panel is also to be understood as meaning panels which are also suitable for covering the ceiling. The panels usually consist of a carrier or core made of a solid material, for example a wood material, plastic or a composite material, which is coated on at least one side with a decorative layer and a cover layer and optionally with further layers, for example a wear layer arranged between the decorative and cover layer, is provided. The decorative layer is usually formed from a printed paper or a decorative printed directly onto the carrier or a decorative substrate initially applied to it. In particular, the so-called direct printing of decor on a carrier or a decor background initially applied to the carrier by means of direct printing processes such as inkjet printing has gained increasing importance in the relevant industry in recent years.
Processes for the production of decorative panels based on carriers made of wood-based materials such as HDF or MDF boards are well known. So reveals the WO 2009/080772 for example a method for producing a decorated laminate with a plate-shaped core made of wood or wood material.

Processes for the production of decorative panels based on a plastic material are also known and usually have process steps, as shown in FIG EP3140129 A1 is shown. For example, a "cake" made of granulate pellets can be placed on the lower belt of a press using a spreader. In the course of production, this cake is usually fed into a hot belt press with steel and / or Teflon belts, in which the granulate pellets are heated and melted. At the same time as melting, the material can be pressed and shaped into a carrier. Then, through controlled cooling, solidification or crystallization of the carrier material is brought about, the waste heat largely remaining unused, since the usable temperature difference due to the controlled cooling is too small for any other use. In this belt press process, the heat is transferred from above and below through contact with the press. Another disadvantage for cooling is that the heat has to pass through the glass fiber reinforced Teflon tape. Only then does the heat transfer through thermal conduction into the granulate bed or the carrier material. These physical processes are very slow because the pellet cake initially still contains air from the bulk granulate, which in terms of product physics can only be slowly pressed out of the carrier. In order to achieve acceptable belt speeds in production, a high temperature gradient must be created for cooling, which leads to considerable waste heat losses.

Regardless of the material chosen for the carrier, the panels obtained in this way are printed and printed as large panels with a multiple of the area of a final decorative panel then divided into individual, customary rectangular panels. The panels obtained in this way can then be provided with profiles on the panel edges, by means of which the individual decorative panels can be joined together to form a connected surface.

So-called herringbone or ear patterns are known from the field of classic parquet, in which periodically arranged parquet strips usually have a translation symmetry at right angles, 45 ° or 30 ° to the right angle.

However, such a laying pattern is expensive to manufacture, since individual rods have to be arranged correspondingly to one another.

The object of the present invention is therefore to provide a decorative panel with which geometrically complex laying patterns, such as for example herringbone patterns, can be easily provided on large laying areas.

This object is achieved by a decorative panel according to claim 1. Refinements of such a decorative panel can be found in the dependent claims and the following description.

The invention thus provides a decorative panel which has a pair of opposing short and long edges, the pairs of opposing edges having mutually compatible geometries, characterized in that at least the opposing long edges of the panel are at least partially not parallel to the longitudinal axis get lost.

It has been shown that with the decorative panel according to the invention it is possible to provide geometrically complex laying patterns such as herringbone patterns in a simple and user-friendly manner even on large laying areas.

In the context of the invention, the term “decorative panel” is to be understood as meaning in particular wall, ceiling, door or floor panels which have a decoration applied to a carrier plate. Decorative panels are used in a variety of ways both in the area of interior design of rooms and for the decorative cladding of buildings, for example in trade fair construction. One of the most common areas of application for decorative panels is their use as flooring. The decor panels often have a decor that is intended to simulate a decor template, usually a natural material.

Examples of such simulated natural materials are types of wood such as maple, oak, birch, cherry, ash, walnut, chestnut, wenge or exotic woods such as panga-panga, mahogany, bamboo and bubinga. In addition, natural materials such as stone surfaces or ceramic surfaces are often modeled on.

The carrier or core of a decorative panel according to the invention can, for example, be a carrier based on a natural material, a plastic or a wood-plastic composite material (WPC). Layer structures made of several of the materials mentioned can also be used, for example plasterboard or wood-plastic layer boards.

For example, the carrier plate can be formed from a thermoplastic, elastomeric or thermosetting plastic. Panels made of minerals such as natural and artificial stone panels, concrete panels, gypsum fiber panels, so-called WPC panels (made from a mixture of plastic and wood), and panels made from natural raw materials such as cork and wood can also be used as supports according to the invention. Panels made of biomass as a natural material such as straw, corn stalks, bamboo, leaves, algae extracts, hemp, oil palm fibers, can also be used according to the invention. Furthermore, recycling materials made of the materials mentioned can be used in the context of the method according to the invention. Furthermore, the panels can be made from cellulose, a natural material, such as paper or cardboard.

Wood-based materials within the meaning of the invention are, in addition to solid wood materials, also materials such as cross-laminated timber, glued laminated timber, rod plywood, veneer plywood, laminated veneer lumber, veneer strip wood and flexible plywood. In addition, wood-based materials for the purposes of the invention also include chipboard materials such as chipboard, extruded boards, coarse chipboard (Oriented Structural Board, OSB) and chipboard wood, as well as wood fiber materials such as wood fiber insulation boards (HFD), medium-hard and hard fiber boards (MB, HFH), and in particular medium-density To understand fiberboard (MDF) and high density fiberboard (HDF). Modern wood-based materials such as wood-polymer materials (Wood Plastic Composite, WPC), sandwich panels made of a light core material such as foam, rigid foam or paper honeycomb and a layer of wood applied to it, as well as wood-based chipboard bonded minerally, for example with cement, form wood-based materials within the meaning of the invention. Cork is also a wood material in the sense of the invention.

For the purposes of the invention, the term fiber materials is to be understood as meaning materials such as, for example, paper and nonwovens based on vegetable, animal, mineral or even artificial fibers, as well as cardboard. Examples are fiber materials made from vegetable fibers, in addition to paper and nonwovens made from cellulose fibers, panels made from biomass such as straw, corn stalks, bamboo, leaves, algae extracts, hemp, cotton or oil palm fibers. Examples of animal fiber materials are keratin-based materials such as wool or horsehair. Examples of mineral fiber materials are made of mineral wool or glass wool.

Furthermore, the carrier can be a plastic-based carrier, that is to say, for example, comprise or consist of a plastic. Examples of thermoplastics are polyvinyl chloride, polyolefins (e.g. polyethylene (PE), polypropylene (PP), polyamides (PA), polyurethanes (PU), polystyrene (PS), acrylonitrile butadiene styrene (ABS), Polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), polyetheretherketone (PEEK) or mixtures or co-polymers of these. The plastics can contain customary fillers, for example talc, calcium carbonate (chalk), aluminum oxide, silica gel, quartz flour, wood flour, gypsum. They can also be colored in a known manner. In particular, it can be provided that the carrier material has a flame retardant.

Thermoplastics in particular also offer the advantage that the products made from them can be recycled very easily. Recycled materials from other sources can also be used. This results in a further possibility for reducing the manufacturing costs.

The carrier material or the material from which the carrier is formed can for example be a matrix material and a solid material, the matrix material in an amount, based on the carrier material, of 25% by weight to 55% by weight, in particular of 35% by weight to 45% by weight, and where the solid material is present in an amount, based on the carrier material, of 45% by weight to 75% by weight, in particular of 55% by weight up to 65% by weight, and where the matrix material and the solid material are present together, based on the carrier material, in an amount of 95% by weight, in particular 99% by weight, and the solid material is at least 50% by weight, in particular at least 80% by weight, in particular at least 95% by weight, based on the solid material, is formed from a solid composition consisting of at least a first layered silicate powder and a second layered silicate powder, and at least the matrix material 50% by weight, in particular e is formed to at least 80% by weight, in particular at least 95% by weight, based on the matrix material, by a plastic composition consisting of a homopolymer and at least one first copolymer and a second copolymer.

Layered silicate powder is understood to mean, in a manner known per se, a powder made from a layered silicate. As is known, sheet silicates are minerals from the group of silicates, the silicate anions of which are usually arranged in layers. For example, sheet silicates are understood to mean minerals from the mica group, the chlorite group, the kaolinite group and the serpentine group.

Thus, the solid material can advantageously be formed at least by a large part of the mineral substance sheet silicate, wherein this substance can be used in powder form or can be present in the carrier material in the form of particles. In principle, the solid material can consist of a powdery solid.

Layered silicates offer the advantage that they can allow the production of a carrier with good mechanical properties and at the same time can be easily processed into corresponding powders due to their layered structure.

In the context of the present application, a “decorative template” can in particular be understood to mean such an original natural material or at least a surface of one that is to be imitated or reproduced by the decor. The decoration can be applied, for example, by applying a printed paper or an unprinted or partially printed paper, which is then printed. Alternatively, the decoration can be printed directly on the carrier or a suitable printing substrate, as described below.

In order to apply a decoration, a decorative background can first be applied to at least a partial area of the carrier. For example, a primer, in particular for printing processes, can first be applied as a decorative background, for example in a thickness of 10 μm to 60 μm. A liquid radiation-curing mixture based on a urethane or a urethane acrylate, optionally with a or more of a photoinitiator, a reactive diluent, a UV stabilizer, a rheological agent such as a thickener, radical scavenger, leveling aid, defoamer or preservative, pigment and / or a dye can be used.

In addition to the use of a primer, it is possible to apply the decor to a decor paper which can be printed with a corresponding decor and which can be provided as a connecting means, for example, by means of a resin layer previously applied to the carrier. Furthermore, a resin can be applied to the paper as a printing substrate, which resin component can have at least one compound selected from the group consisting of melamine resin, formaldehyde resin, urea resin, phenolic resin, epoxy resin, unsaturated polyester resin, diallyl phthalate or mixtures thereof. In the method according to the invention, the primer can preferably be applied to the carrier plate by means of rubber rollers, a casting machine, or by spraying. The primer is preferably used in an amount between 1 g / m ² and 100 g / m ² , preferably between 10 g / m ² and 50 g / m ² , in particular between 20 g / m ² and 40 g / m ² applied. After the primer has been applied to the carrier surface, it is irradiated with a radiation source of a suitable wavelength.

Alternatively or in addition to the primer, for example on the primer, a primer can also be applied directly to the carrier or to the primer. For a decorative image of particularly high quality from a visual point of view, for example, a white colored primer can be applied, which can have white color pigments, for example. For example, the primer can be applied in two layers. It can be particularly preferred for the primer to be radiation-curable, for example UV-curable. A first layer of primer can then preferably be cured before applying a further layer of primer and / or before the decoration is printed on. For example, the primer can comprise polyurethane, for example be designed as a polyurethane varnish, and for example be provided with white pigments.

According to a further embodiment, the decoration or the decoration layer can be applied by direct printing. In the context of the invention, the term “direct printing” can be understood to mean the application of a decoration directly to the carrier of a panel or to a non-printed fiber material layer applied to the carrier. In contrast to the conventional methods in which a previously printed decorative layer is applied to a carrier, in the case of direct printing the decor is printed directly in the course of the panel production. Different printing techniques such as flexographic printing, offset printing or screen printing can be used. In particular, digital printing techniques such as inkjet processes or inkjet printing processes or laser printing processes can be used. The aforementioned printing processes are particularly well-engineered and particularly suitable for panel production in order to be able to apply a true-to-detail decor identical to the original. In the context of the invention, direct printing is also to be understood as the application of the decoration by means of printing techniques to a printable layer previously applied to the carrier. Such a printable layer can be formed, for example, by a liquid applied and then cured primer layer or also a previously applied printable film, paper or fleece layer.

In particular, a digital printing method can be suitable for the method described above, since the three-dimensional decor data are preferably provided in electronic form or in digital form. This can apply, for example, both to data stored in a database and to data determined in situ by a three-dimensional scanner. Thus, the provided decor data can be used directly in particular by digital printing processes without further intermediate steps, which makes the process particularly applicable in this embodiment with particularly little effort and at low cost. In addition, through the use of digital printing processes, it is possible to carry out each printing process individually, so that a particularly wide range of applications and dynamic adaptation to the desired product are possible.

The decorative layer or the decor can be formed from an in particular radiation-curable paint and / or ink. For example, a UV curable paint or ink can be used.

A cover and / or wear protection layer can be provided above the decorative layer to increase the resistance. To form a corresponding cover layer, it can be provided in one embodiment that a radiation-curable composition containing hard material is applied in a concentration between 10 g / m ² and 250 g / m ² , preferably between 25 g / m ² and 100 g / m ² . The application can be applied, for example, by means of rollers, such as rubber rollers, or by means of pouring devices.

It can be provided that the hard material is not contained in the composition at the time of application of the top layer composition, but rather is sprinkled onto the applied top layer composition as particles and this is then hardened by radiation.

In particular, a structuring, in particular a surface structuring that matches the decor, can be introduced into the cover layer by introducing pores, which is also referred to as synchronous pores. This can be realized, for example, by so-called negative structuring, in that the cover layer is provided with a structure by means of an embossing means, such as an embossing die or an embossing roller, in that it is pressed into the cover layer. For this purpose, the top layer can first be partially hardened, then provided with a structure and then further hardened.

When the cover layer is formed with lacquers, the structure can also be introduced by what is known as positive structuring, in which the structures are built up by applying a layer of lacquer and in particular by selectively applying the raised areas of the structure. This is often realized by negatively structured embossing means, which can apply the lacquer layer accordingly.

A mutually compatible geometry of the edges is to be understood in the context of the invention that the geometry of a first edge is designed in such a way that a second edge can be placed on the first edge in a form-fitting manner.

According to one embodiment of the invention, it can be provided that at least 50% of the total edge length of the long edges of the panel, preferably at least 60%, in particular at least 75%, do not run parallel to the longitudinal axis.

Such a design of the edges makes it possible to recreate geometrically complex laying patterns not only within a single decorative panel, but also across different panels, so that the realistic replication of corresponding laying patterns is no longer limited to the size of a single decorative panel, but also over large laying areas can be simulated in a simple and user-friendly manner.

According to a further embodiment of the invention, it can be provided that the opposite short edges of the panel, at least in sections, do not run parallel to the transverse axis of the decorative panel. It can be provided in particular that at least 50% of the total edge length of the short edges of the panel, preferably at least 60%, in particular at least 75%, do not run parallel to the transverse axis of the decorative panel. Such a configuration makes it possible to simulate geometrically complex laying patterns also in the longitudinal direction over a plurality of panels.

According to a further embodiment of the invention, it can be provided that the long edges have edge sections which enclose an angle to one another in a range between 30 ° and 120 °. This enables complex installation geometries such as herringbone or ear patterns to be displayed across decor panels.

According to a further embodiment of the invention, it can be provided that a short edge has edge sections which enclose an angle to one another in an area between them. It can also be provided that a short edge has edge sections which are at an angle to one another in a range between 30 ° and 120 °. In particular in one embodiment in which a first short edge of a decorative panel has edge sections which enclose an angle to one another in a range between 30 ° and 120 ° and a second short edge has edge sections which are at an angle to one another in a range between 30 ° and ≤120 °, decorative panels can advantageously be placed against one another in the longitudinal direction.

According to a further embodiment of the invention, it can be provided that the pairs of the respective opposite edges have mutually compatible geometries, the opposite long edges of the panel being curved or wavy. In such an embodiment, too, the edges, at least in sections, do not run parallel to the longitudinal axis. This allows more complex laying patterns to be displayed. The long edges can have different radii.

It can also be provided that the radius changes along the longitudinal extension of the long edge, in particular that a repeating amplitude or radius pattern results along the longitudinal extension of a long edge. It can preferably be provided that the amplitude or radius pattern is symmetrical. This advantageously allows panels that are adjacent to one another along their longitudinal direction can be arranged offset to one another, with compatible radii of a first panel being able to be created in compatible radii of a second panel.

According to a further embodiment of the invention, it can be provided that the pairs of the opposite edges have mutually compatible locking means for forming a locking mechanism that locks at least in the vertical direction. Examples of corresponding locking means are tongue and groove profiles or hook profiles. The locking means can be designed in one piece, with a locking element effecting a locking being designed integrally with the carrier, such as, for example, a spring profile worked onto the carrier in the relevant edge region.

Alternatively, a blocking element can also be present separately and only activated or introduced at the moment of the connection of two decorative panels placed next to one another. An example of this is the formation of groove profiles on the opposite pairs of edges and the introduction of a separate tongue as a locking element between the grooves, which locks the panels to one another in at least a vertical direction. Another example of a possible separated locking element is a spring element introduced into a groove of an edge of a first decorative panel, such as a resilient latching tab, which is initially tensioned when two decorative panels are joined together along compatible edges and then relaxed and partially relaxed when a locking position is reached engages in a locking groove of a second decorative panel and thus causes locking in at least the vertical direction.

It can also be provided, for example, that the edges of a decorative panel according to the invention have profilings and / or locking means which effect locking in the vertical direction as well as in the horizontal direction.

In addition, the invention specifies a method for producing a decorative panel according to the invention. Such a method has the step of dividing a large panel comprising a multiple of the area of a decorative panel by means of a cutting means that is freely movable in at least 2 axes.

A correspondingly suitable cutting means can be, for example, an electromagnetic radiation source such as a laser, compressed air jet or a water jet. A laser is particularly preferred.

In the case of an electromagnetic radiation source as the cutting means, it can be provided that the profiling tool have a deflection device, such as a mirror, prism or a magnet. The cutting means can also be moved freely in at least 2 axes by means of such devices.

According to a further embodiment of the invention, the method has the step of profiling at least one pair of opposite edges, the profiling being carried out by means of a profiling tool that is freely movable in at least 3 axes. The profiling tool can be, for example, an electromagnetic radiation source such as a laser, compressed air jet or a water jet. A laser is particularly preferred.

In a particularly preferred embodiment of the invention, it can be provided that a large board printed with a decoration and provided with a cover layer, which has a multiple of the area of a decoration panel, is in a first process step by means of a 2-axis cutting means, in particular by means of a 2nd -axially guided laser, first individual decorative panels are divided, which after the division each have a pair of opposite short and long edges, the pairs of opposite edges have mutually compatible geometries, characterized in that at least the opposite long edges of the panel at least in sections do not run parallel to the longitudinal axis and are then profiled along at least the long edges by means of a 3-axis guided cutting means, in particular by means of a laser, locking means being formed.

It can be provided in particular that structural means are also formed in the course of the profiling for the formation of locking means. In the context of the invention, structural means are to be understood as meaning, for example, chamfers on the decor-side edges of the edges for the formation of V-joints.

The decorative panel 100 each has a pair of opposing short edges 130, 140 and long 110, 120 edges, the pairs of opposing edges 110, 120, 130, 140 having mutually compatible geometries. In the context of the invention, a mutually compatible geometry of the edges is to be understood as meaning that the geometry of a first edge (110, 130) is designed such that a second edge 120, 140 can be positively applied to the first edge 110, 130 . According to the invention, it is provided that at least the opposite long edges 110, 120 of the panel 100, at least in sections, do not run parallel to the longitudinal axis 150.

In the embodiment shown,> 90% of the total edge length of the short edges 130, 140 of the panel do not run parallel to the transverse axis 160. The long edges 110, 120 have edge sections 111, 112, 121 , 122, which enclose an angle to one another in a range between 30 ° and 120 °, here approx. 90 °. A short edge 140 has edge sections 141, 142 which enclose an angle to one another in a range between 30 ° and 120 °, here approx. 90 °. The opposite short edge 130 has edge sections 131, 132 which are at an angle to one another in a range between 30 ° and 120 °, here approx. 90 °. The pairs of opposite edges 110, 120, 130, 140 preferably have mutually compatible locking means (not shown here) for forming a locking mechanism that locks at least in the vertical direction. In this way, two decorative panels according to the invention can be connected to one another in a simple manner to form an essentially integral covering surface. The long edges 110, 120 of a first decorative panel engage in an offset manner in the long edge of a second decorative panel, so that, for example, an edge section 111 of a first decorative panel binds to the edge section 122 of a second decorative panel. The locking means can be designed in one piece with the core of the decorative panel or as a separate locking element or blocking element that can be separated from the decorative panel. In the simplest form, a groove on the edge portions of the first long edges 110 and a tongue on the edge portions of the second long edge 120 can be provided as the locking means, so that when two decorative panels are joined along their respective long edges 119, 120 the tongue of the second edge engages in the groove of the first edge. Alternatively, it can be provided that the long edges 110, 120 have a groove as a locking means, into which a separate tongue is inserted as a locking element, by means of which the two panels are connected to one another. It can also be provided that the locking means on the long edges 110, 120 or the edge sections 111, 112, 121, 122 have locking means which, in addition to a locking acting in the horizontal direction, also effect a locking acting in the vertical direction. For this purpose it can be provided that the locking means Are hook-shaped and have a locking element, such as a resilient latching tab. Such a resilient locking tab can be an integral part of the decorative panel or be provided as a separate element. Likewise, compatible locking means can be provided on the short edges 130, 140 on the edge sections 131, 132, 141, 142, by means of which decorative panels can also be connected to one another along the longitudinal axis. In this case, these locking means can be configured in a comparable manner to the locking means provided on the long edges 110, 120 or the edge sections 111, 112, 121, 122.

Fig. 2 shows a plurality of decorative panels 201, 202, 203 which can be joined together along their respective long edges to form a larger covering surface.
