  • the present invention relates to the production of the new, surface-coated decorative laminates, which are used in particular as construction, floor and furniture panels.
  • the basic manufacturing process is such that a print decoration provided with any print or, in some circumstances, a mere, e.g. B. uniformly colored, otherwise unprinted paper with a hard, especially thermosetting resin, preferably impregnated with an optionally modified, melamine, formaldehyde and / or urea resin and then or later with a - usually multi-layer - also with a thermosetting Resin or resin mixture, impregnated fiber, in particular paper web, which Unteriags- and / or carrier function, for. B. for an abrasive coating, and is usually referred to as a core sheet, preferably pressed under the influence of heat to a laminate sheet with the desired surface decor and / or desired surface structure.
  • this decorative laminate web If the resin of this decorative laminate web is essentially fully polymerized, that is to say hardened, it can be bonded to the substrate, usually a wood chipboard or wood fiber board, by adhesive bonding, possibly hot press bonding.
  • the invention has now set itself the task of creating a new laminate material based on wood materials with a hard-wearing decorative coating, with which the decorative coating in addition to the desired color and while reducing the effort for the laminate components and the production costs / or a print decor provided in each case shows an optical or other additional effect related to the appearance and structure of the surface of the respective substrate material.
  • the production of the decorative laminate web that is ultimately to be applied to the substrate surface is relatively complex only in that at least the printing decor that is provided as the outermost layer on the visible side or an overlayed paper web and the core-paper web formed in most cases with a plurality of layers must be combined after impregnation with the curable resin.
  • This can take place immediately in the resin-wet state or after individual partial hardening to form prepreg sheets, which in any case requires considerable mechanical and manipulation effort in addition to the material expenditure.
  • This multi-layer coating on the visible side also makes it necessary to coat the opposite side of the wood-material panels with a mostly multi-layer counter-coating to avoid warping or warping of the panels.
  • any impression of the surface of the substrate is completely lost.
  • the present invention thus relates to a new decorative laminate material based on a wood material, preferably in the form of boards, with a base substrate made of the said wood material, preferably wood fiber and / or wood chipboard, to which or which has a decorative coating based on paper impregnated with a hardened resin, at least on its visible surface, and which or which has a counter-coating on its non-visible surface, also based on paper impregnated with heat-hardened synthetic resin.

  • wood material is not only limited to wood fiber or chipboard materials, but should also be understood to include plywood, OSB, wafer board, recycling boards (which do not necessarily have to consist only of wood). The following is explained in more detail about the prior art in the field in question and the position of the laminates according to the invention in this environment:
  • DE 43 41 590 A1 describes a coating method which is similar in principle, but there is by no means an attempt to show through and / or even reproduce the relief of the underlay structure on the coating; rather, in accordance with this DE-A1, an artificial surface structuring is used by means of massive application of paint , e.g. in the manner of a grain.
  • an artificial surface structuring is used by means of massive application of paint , e.g. in the manner of a grain.
  • the surface consists of a paper-based film.
  • a film labeled in this way should perhaps have a paper layer, but it only forms a basis.
  • the DD 256 478 A1 appears to be somewhat closer to the subject of the invention on first inspection.
  • page 2 the possibility of single-layer foils, which are pressed onto the substrate, is discussed there, but here, too, there is only talk of intentionally creating an artificial structuring of the surface by the action of the press. Participation of the substrate and its texture in the final appearance of the surface of the coated wood-based panels is not desired there and seems undesirable.
  • E 20 214 B which, however, provides for at least two-layer coatings, e.g. with at least one cellulose or paper layer and a resin-impregnated decorative film, and which font is more of a technological background.
  • Effects are the pigment components worked into the paper, e.g. B. lightening and white pigments, fillers or the like. To see.
  • the use of after resin curing at least “translucent” papers, as indicated above, are advantageous. Under “translucent effects” any existing z. B. caused by zones of different amounts of filler pigment differences in transparency, z. B. to understand in the manner of a marbling.
  • Resin-impregnated papers have been included for the new decorative laminate materials
  • Basis weights according to claim 3 have been shown to be favorable, since on the one hand there is still no dominance of the substrate and its structures, which may already be perceived as a disturbance of the decor, but on the other hand the substrate effect is not yet fully covered.
  • Claim 6 provides information as to the preferred amounts of the synthetic resin infiltrated into the paper with the decor after it has hardened.
  • the surface carrying the decorative coating is mechanically surface-treated, e.g. B. ground, sandblasted, compressed or the like, is as provided in claim 9.
  • the invention further relates to a method for producing the new decorative laminate materials based on wood materials, as described above, the coating paper with a solution and / or dispersion or emulsion at least one thermosetting synthetic resin, preferably based on melamine / formaldehyde and / or melamine / urea, is impregnated and either the still impregnated-moist paper web or the mentioned paper web after partial curing of its synthetic resin, preferably in the form of prepreg -Blades or sheets, is bound to form a decorative coating at resin curing temperature and under pressure to the surface of a wood material substrate.

  • Previously known wood-material panels were and are provided with a surface coating by means of printed papers, which serve both for the optical design and for improving the surface quality.
  • This surface is made up of several layers of paper, the top layer being formed with a so-called overiay.
  • this overlay is mostly transparent and serves to improve the surface quality, for example the abrasion values.
  • the desired optical and other effects are achieved by layers of paper underneath. This means that any patterns or a replica of a wood grain are only printed on the paper layer underneath the overlay.
  • a backing paper is normally applied to the back of the wood-material boards in order to prevent the boards from bending through the papers on the "front".
  • the strength of the backing paper which itself usually consists of several layers of paper, is measured according to the number of papers and their thickness on the visible or front side.
  • the papers are soaked in a resin and pressed under pressure at elevated temperature with the wood-material plate and with each other.
  • a commercially available melamine-urea resin dispersion is used to obtain a commercially available overiay paper impregnated on the visible side with the heat-hardened resin, and with a desired print decor, and on the underside with a similar but not printed overiay -Paper coated high density wood fiber (HDF) board.
  • HDF high density wood fiber
  • a panel with the decor on the visible side was obtained, the color shades and the fiber structure of the HDF panel surface being permanently visible through the print decor.
