Description

Material plate with graphical surface structure

The invention relates to a material plate, in particular for the production of furniture, floor coverings or door elements, comprising at least one middle substrate layer and a decorative layer on at least one side of the substrate layer.

Material plates of the generic type are mainly used for the production of furniture, door elements or floor panels. Here, a fibrous material is used for the production of the material plates, which is at least on one side, preferably coated on both sides with several layers to be connected to each other in a press by melting a hot melt adhesive. For this reason, the layers are impregnated with an aminoplast resin, for example melamine-formaldehyde resin, so that the aminoplast resin layer can cure on pressing under simultaneous exposure to heat and a connection of the individual layers to the substrate layer is produced. The layers used in this case consist of at least a decorative layer and an overlay layer. The decorative layer can consist of a replica of a natural wood or rock surface.

Such produced material plates are preferably used for the production of furniture. It is also possible to produce door panels or panels for floors or walls. Preferably, in this case, patterns are used which have a wood grain, wherein it is important that they reproduce as faithfully as possible, both with regard to the printed image (decorative layer) and the required embossing. For this reason, press plates are used which have a negative impression of the material plates to be pressed. Thus, in the pressing process, the structure of the press plate can be transferred to the upper cover layer of the substrate layer. For this purpose, large press plates in a format of 2.3 x 6 m are usually used to produce large-sized material plates, which can then be tailored in the furniture industry for the respective intended use. The same applies to panels and door leaves. To meet individual customer requirements and to realize new patterns, the present invention has the object to show a material plate and a press plate, which allows a diverse design

To achieve the object it is provided that the decorative layer has adjacent adjacent districts, which at least partially have a decor and / or structure course with different directions. Further advantageous embodiments of the invention will become apparent from the dependent claims.

Contrary to the previous trend to provide door leaves, furniture doors or fronts with a uniformly extending decor, which consists essentially of a wood grain and has passagenike imprinting, is taken from this previous approach distance and a decorative layer chosen, which has adjacent adjacent districts, said Districts at least partially have a decor and / or structure course with different directions. The material plate is thus divided into a plurality of adjacent districts, which differ from the conventional sampling, the result of strictly graphic pattern, which in turn have a decor and / or structure course, which runs in different directions. Thus, attractive patterns are achieved, which can be used future-oriented and in an attractive manner in the furniture industry. The individual districts can have an exact fit embossing, both with regard to the course of the decoration and the course of the structure. Underpassage-precise embossing is understood to mean a special embossing, in which the pattern of the decorative layer coincides with the embossed structure of the press bale. Thus, for example, wood pores can be particularly highlighted by appropriate depth embossing, so that the impression arises for a viewer, it is naturally grown wood, which further creates a haptic by the existing embossing, which gives the impression of a natural wood material during scanning. The use of a wood decor is mentioned here only for example, it may also be the structure of a granite surface or other natural materials. Due to the design and different structuring of adjacent adjacent districts in this case a surface design is achieved, which opens up new and diverse design options to produce surfaces of furniture, door panels or floor panels.

In a further embodiment of the invention provides that the areas of the decorative layer ^¬ an irregular edge configuration, particularly following a polygonal line having, adjacent areas may have a common edge line at least partially. The individual districts are thus strictly separated from each other and can at least partially have a common edge course. The decisive factor is that the districts themselves can be varied in their size and shape as desired, and thus the possibility exists of displaying an irregular edge course, as it follows, for example, a traverse. Alternatively, there is the possibility that the districts consist of simple geometric shapes, in particular of circles, triangles, polygons or rectangles, with an at least partially straight edge course. Even in this shaping, adjacent districts have a partially common edge course or can additionally penetrate each other. In this case, penetration is understood to mean that individual forms, for example a triangle, protrude with a tip into another district. Thus, it is possible to shape the districts so that they either have only an irregular edge course or are combined with strictly geometric shapes. For example, a part of the edge course could run strictly straight line and another part curved, wherein the plurality of different districts are arbitrarily combinable, so that similar to a puzzle individual districts are joined together.

To produce the material plate in this case a decorative layer is used, which consists of at least a decorative paper and an embossing on one side of the material plate. For this purpose, presses are used, which can make both an embossing on the front and possibly on the back of the material plate, wherein the press plates used preferably with a passagen- Outside negative structure of the surface to be produced are provided. Due to the conformity of the press plate structure with the decorative paper, the impression of inlaying with correspondingly raised and lowered areas in the individual areas is achieved in the present case.

Depending on the intended use, the material plates can hereby be provided on one side or optionally on both sides with a decorative layer and an embossing. For connecting the individual layers to the substrate layer, it is provided that at least on one side, preferably on both sides, a glue layer is arranged between the substrate layer and the decorative layer.

In order to be able to emboss particularly deep structures, one or more underlay layers are preferably interposed between the substrate layer and the decorative layer, which may consist, for example, of resin-impregnated kraft paper or resin-impregnated glass nonwoven fabric. Such an arrangement is selected for at least one side of the material plate, optionally on both sides. Thus, it is possible to characterize particularly deep structures without having to emboss the substrate layer.

In order to achieve particularly high-quality surfaces, which are also resistant to conventional cleaning agents, it is further envisaged that a layer sequence overlay layer, decorative layer is provided on at least one side of the material plate. With the help of the overlay layer, which is usually made transparent, the sensitive decorative layer is ultimately protected, whereby the overlay layer can be soaked with a glue layer, that is with an amino resin, so that a permanent connection between the overlay layer, decorative layer and substrate layer can be produced.

Insofar as a high abrasion resistance of the produced surfaces of the material plates is desired, the decorative layers and / or overlay layers can be further enriched with abrasion-resistant particles. Abrasion-resistant particles are essentially However, even hardened melamine or glass can be introduced into one of the upper layers in order to make the layer more abrasion-resistant and more stable against abrasion.

In principle, fibrous or chip-containing materials can be used as the substrate layer, such as MDF, HDF, chip, OSB or plywood. Here it depends on the desired quality and strength of the material plate in order to be able to use it, for example, as a material plate for the furniture industry or the like.

The invention is also based on the object to show a novel press plate, which is suitable for the production of material plates with different districts.

The object is achieved in that the press plate has a surface structure having adjacent adjacent districts, which has at least partially a decor and / or structure course with different directions.

In order to make the embossing of the material plates as simple as possible and to enable, for example, a passport precise embossing of the material plates, a press plate is proposed which has a corresponding negative structure in the desired shape with the generation of different districts. The individual districts have at least partially a decor and / or structure course in different directions, so that strict graphic patterns arise.

In an embodiment of the invention, it is provided that the press plate is subdivided into individual districts, which have an irregular edge profile, in particular following a traverse. The districts of the press plates are in this case arranged directly next to one another and consequently have a partially identical edge course. Decisive, however, the individual districts have a preferred direction with respect to their grain or structuring, which run in different directions, thus any graphic pattern can be generated, which, for example, example, may have an irregular edge profile. Alternatively, there is the possibility that the districts of simple geometric shapes, in particular of circles, triangles, polygons or rectangles having an at least partially straight edge profile, wherein adjacent districts can also be formed penetrating each other.

The design of the press plates with individual districts, which at least partially have a different structural course in different directions creates the opportunity to subject the material plates of a corresponding embossing. Here, the districts of the press plates are so far adapted to the decor pattern that a passport precise embossing can be made.

The particular advantage of the present invention is that any geometric figures can be made to perform a surface structuring. This can be done, for example, by merely making an edge course of the individual districts in an irregular shape, but it is also possible to additionally provide the individual districts with their own structure, which points, for example, in different directions. Thus, a strictly graphic motif is created, which is suitable both for furniture production and for the production of door elements or panels, be it for floors or for walls.

The invention will be explained again with reference to two Ausführungsbeispieie in the drawings.

It shows

1 is a perspective view of a material plate,

Fig. 2 in a perspective Expionsionsdarstellung the material plate with a layer sequence and a congruent printing decor and Fig. 3 is a plan view of a press plate for producing the material plate.

FIG. 1 shows, in a perspective view, a material plate 1 which consists of a middle substrate layer 2 and at least one decorative layer 3 resting on the upper side. In the illustrated embodiment, the decorative layer 3 is divided into individual districts 4, which have a structuring 5. The individual districts 4 in this case have an irregular edge profile 6, wherein adjacent districts 4 have in part a common edge course 6 and the structuring 5 of the individual districts 4 point in a different direction, so that a graphic design with irregularly shaped districts 4 is formed. In the exemplary embodiment, a wood grain is shown, but it is possible to arrange any structuring in this way, for example, fiber structures with a preferred direction in the respective districts 4, so that graphical patterns arise.

FIG. 2 shows in a perspective view a further embodiment of a material plate 10, which consists of a middle substrate layer 12 and at least one decorative layer 13 resting on the upper side. Compared to the embodiment of Figure 1, the districts formed here 14 are provided with a straight edge profile, so that, for example, individual districts 14 in the form of a triangle, a trapezoid, a rectangle or a rhombus result. Just as in the first embodiment, the structuring 15 is arranged in different directions, so that in this case, too, a strictly graphic pattern is created. A combination of the two alternative embodiments is also conceivable.

3 shows a perspective exploded view of the material plate 1, 10 according to FIGS. 1 and 2. It can be seen from this illustration that the material plate 1, 10 consists of a middle substrate layer 2, 12 onto which a decorative layer 3, 13, an underlay Layer 20, 21 and an overlay layer 22, 23 is placed. The decorative layer 3, 13 in this case has a decor with individual districts 4, 14, so that after completion of the material plate 1 creates the impression of a graphic pattern. The decorative layer 3, 13 itself is through the underlay layer 20, 21 and overlay layer 22, As a result of the heating during the pressing process leads to a permanent permanent connection between the overlay layer 22, 23 and the underlay layer 20, 21 and between the underlay layer 20, 21 and decorative layer 3, 13. Similarly, a firm connection between the decorative layer 3, 13 and the substrate layer 2, 12 hergesteift. By means of the underlay layer 20, 21, a particularly deep embossing of the structures is made possible, while at the same time, with the aid of the overlay layer 22, 23, it is ensured that the surface has sufficient protection against cleaning agents, etc. However, there is no absolute necessity to provide the overlay layers 22, 23 or, if appropriate, further overlay layers 3, 13, provided that, according to the customer's request, only the decorative layer should be used as the outer layer.

Furthermore, there is the possibility that the row of the individual layer sequence is varied with one another, for example a glue layer can first be applied to the substrate layer 2, then the decorative layer 3, 13 and subsequently an overlay layer 22, 23. Furthermore, between the individual layers, as far as these are not impregnated themselves with an amino resin, glue layers are arranged, which ensure the connection after heating and curing. In the present case, it is not so much the nature of the sequence of the individual layers, but rather the fact that the decorative layer 3, 13, in which position this is always incorporated in the layer sequence, a graphic design with individual districts 4, 14 has.

FIG. 4 shows a plan view of a press plate 50, which is subdivided into individual regions 51 in accordance with the material plate 1. The individual regions 51 have an irregular edge profile 52, each with its own structure 53, whose main preferred direction points in different directions. The wood grain shown can be replaced by comparable structures, for example fiber structures or the like with a main preferred direction. LIST OF REFERENCE NUMBERS
