Definitions

  • the invention relates to a decorative paper for a laminate.
  • the invention relates to a laminate, in particular for a floor, with a decorative paper.
  • the invention relates to a method for producing the decorative paper.
  • Decorative papers of the type mentioned above are constituents of laminates, which are in the form of laminates, which are formed by pressing, gluing and / or gluing at least two layers of the same and / or different material.
  • the top layer contains a so-called overlay paper impregnated with synthetic resins, for example melamine resins, which contains abrasive particles embedded in the resin such as corundum particles to increase the abrasion resistance of the floor ,
  • the overlay paper can also contain fibrous, in particular cellulosic, material.
  • this uppermost layer is a printed or unprinted paper impregnated with resin, usually with melamine and / or urea resins, the so-called decor paper which forms the decorative layer of the finished floor and consists of an impregnated base paper layer and a color layer and / or a pattern or decorative printing.
  • a support plate is usually a wood-based panel, z.
  • a fiberboard such as a high-density fiberboard (HDF) or a medium-density fiberboard (MDF), or a particle board or a wood-based panel of oriented-scattered microfubers, a so-called O [riented] S [trand] B [oard].
  • An alternative product design is that the Overlayimlessnessgnat is saved for cost reasons and instead the decorative paper is provided on the upper side with a resin layer, which is provided to protect the print layer with corundum particles.
  • the pressing of the carrier plate and decorative paper takes place at a laminate flooring manufacturer, which in principle has the interest to offer alternative product structures of laminates, which can be produced inexpensively and also within the framework of existing standardized compression molding.
  • the core idea of the invention is to be able to offer the processor, ie the laminate flooring manufacturer, an impregnate, which he can preferably process on his existing standardized short-cycle presses.
  • This impregnate can advantageously be pressed onto wood-based panels as part of a normal short-cycle pressing process.
  • the pressing can be done both with an overlay impregnate as a top layer and without this.
  • the hitherto conventional laminate flooring is obtained.
  • the side of the decor paper facing in a laminate of the carrier plate is referred to as the underside.
  • the upper side of the decorative paper is the side facing in a laminate an overlay impregnate or a lacquer layer.
  • the decorative paper according to the invention can also be pressed without Overlayimagnegnat to paint the decorative paper after pressing on a wood-based panel top side with a corundum paint and / or another topcoat.
  • An advantage of the invention is that the processor with the decorative paper impregnated on one side of the invention is given the opportunity to produce two different end products, namely the classic overlaminated impregnated melamine laminate floor panel as well as the corundum-coated panel.
  • the further processor permanently has a stable color base for its subsequent decorative patterning, for example in direct printing.
  • the underside of the paper is provided with an impregnate in the form of a coating order.
  • This preferably contains as a base a plastic, preferably a thermosetting synthetic resin, preferably melamine and / or urea resin and may further be provided with acrylate resin.
  • the coating application includes a thermosetting resin.
  • a practicable variant of the invention provides that the underside of the paper is provided with a coating order.
  • an advantageous embodiment of the invention provides that the coating application contains an antiblocking agent.
  • the decorative paper is unprinted.
  • the processor is the opportunity to permanently have a stable color base for a subsequent Dekorausmusterung, for example, in direct print.
  • the unprinted (uni) decor paper provided with the resin coating on one side first to be pressed under pressure and the effect of temperature on a wood-based panel in order then to provide the non-impregnated side with a pressure. After application of the pressure, the compressed wood-based panel can be provided with a paint job.
  • the top of the decorative paper is providable with a surface finish.
  • the decor paper according to the invention can be pressed without overlay paper to paint the top of the decorative paper according to the invention with the surface finish in the form of a corundum paint and another topcoat.
  • the top of the decor paper is providable with a primer to which the surface finish can be applied.
  • an impregnation of a printed or unprinted base paper layer takes place, which for reasons of cost, preferably undergoes a one-sided, back-side impregnation with a thermosetting synthetic resin, advantageously urea resin and / or melamine resin.
  • a thermosetting synthetic resin advantageously urea resin and / or melamine resin.
  • the top of the decorative paper thus produced which can be overcoated at a later stage, is doctored off.
  • the resin application compared to the usual order quantities of 50% solid resin content, based on the dry weight of the decor paper, significantly below.
  • the associated reduced resin weight on behalf as well as the use of urea resin result in a considerable cost saving.
  • the underside of the decorative paper is now coated with a layer comprising a resin, preferably a thermosetting resin.
  • a resin preferably a thermosetting resin.
  • This process step is preferably realized in the context of an online application process by providing the underside of the printed or unprinted base paper layer (decorative paper) with a coating application after the pre-drying has taken place via an application device.
  • the additional addition of water is preferably dispensed with both during the impregnation which has already taken place and also during the coating of the underside. Furthermore, expediently dispensed with the addition of penetration aids such as wetting agents.
  • the addition of the acrylate resin in the coating of the underside of the base paper layer has the advantage that a better first adhesion to the woodworking board and a poorer penetration into the decorative paper according to the invention is achieved.

  • the decorative paper 100 has a plurality of layers, with the uppermost layer serving as a color layer 17, which is applied to the base paper layer 10 as part of a laminate production process in an upstream operation.
  • a base paper layer 10 is shown, which is decorative printed with a printing ink 17.
  • the base paper layer 10 can also be printed in one pass before impregnation as part of a laminate production process, wherein in a terminology used here, the surface of the base paper layer 10 facing the layer 17 is referred to as the top 11. Accordingly, the side facing away from the layer 17 of the base paper layer 10 is referred to as bottom 12.
  • a further terminology can be made such that, in a laminate, the underside 12 is the side of the base paper layer 10 facing the carrier plate 18 ( Fig. 3 ).
  • the base paper layer 10 is due to the impregnation with resin 13 - in Fig. 1 illustrated dotted - soaked. In addition, goes out Fig. 1 show that the base paper layer 10 is provided with cellulose fibers 14.
  • the base paper layer 10 with the layer 17 represents a conventional decorative paper, which is particularly integral part of laminates for floors.
  • this conventional decorative paper is extended by a further layer 16, as the decorative paper 100 on one side coated, impregnated, wherein the bottom 12 of the decorative paper 100 is provided with a coating order 15 in the form of a preferably thermosetting resin application.
  • Fig. 1 shows layer 16, that is, the coating order 15, is as out Fig. 2 to 4 emerges, between the base paper layer 10 and the support plate 18 is arranged.

In the form of melamine resins impregnated overlay paper, which in the in Fig. 1 embodiment shown to increase the abrasion resistance of the laminate floor in the layer 19 embedded abrasive particles 22 such.
  • B. contains corundum particles.
  • the overlay paper may further comprise fiber-containing, in particular cellulose-containing material 21.
  • fiber-containing in particular cellulose-containing material 21.
  • layers in the form of overlays are commonly used, which consist of two transparent melamine resin impregnated Consist of papers between which a base layer is enclosed.
  • Fig. 2 is between the layers 17 and 20 graphically given a distance that is intended to illustrate that the in FIG. 2 Layer sequence shown in a state before pressing with the support plate 18 is located.
  • Fig. 3 illustrates the state of the layer sequence 200 in a laminate after compression 23 with the support plate 18.
  • the compression 23 triggers a diffusion process such that particles of the resin 20 in the layer 19 as well as particles of the resin 13 in the layer 10 diffuse into the respectively underlying layers 17, 15.
  • the particles in the layer 16, ie the resin particles of the coating application 15 diffuse as a result of compression 23 in the underlying support plate 18.
  • This diffusion process is of importance, as this further processing of the laminate, for example.
  • the connection with the support plate 18 serving as carrier is thus produced
  • FIG. 4 An alternative layer sequence 200 within the scope of the invention proceeds Fig. 4 out.
  • This alternative layer sequence 200 is that in the Fig. 2 and 3 shown top layer 19 is replaced in the form of Overlayim Weggnatpapiers by a top coat applied paint layer 25, which is interspersed with smaller corundum particles 26 to protect the decor paper 100.
