Benefits of technology

The invention relates to a method for making a laminated board with a decorative layer. To prevent expansion of the paper during the hot-pressing process, the invention uses a dry paper layer without any impregnating resin. By doing this, the paper does not absorb the resin and the risk of insufficient bonding due to uneven absorption is eliminated. The method also takes into account the effect of ink absorption on the paper expansion. With this method, the ink is printed on a low-quality paper, and a lower amount of resin is used to prevent excessive expansion. The invention also provides a resin content adaptation based on the resin content of the layers above and beneath the decorative layer to ensure a tight and permanent bond. Overall, this method simplifies the lamination process and reduces the risk of paper expansion.

Problems solved by technology

As a result, there is no danger of the dry core absorbing so much resin that the quantity remaining on the surface is insufficient for firm bonding.

Embodiment Construction

[0035]Board 1 shown in FIG. 1 is a board 1 according to the prior art. Decorative layer 4 is applied to top side 2 of core 3 made of HDF material (high-density fibreboard). Decorative layer 4 has a graphic representation 5 of an imitated material. Decorative layer 4 is provided with cover layer 6 comprising an overlay impregnated with resin. Surface structure 7, which simulates the surface of the imitated material, is embossed on the overlay. The objective is for graphic representation 5 of decorative layer 4 to be positioned exactly on top of embossed surface structure 7 of cover layer 6. In this way, the optical impression of graphic representation 5 is intended to match the tactile impression of embossed surface structure 7.

[0036]According to the prior art, decorative layer 4 is made of printed paper, which is also impregnated with resin prior to hot-pressing. The decorative paper lies directly on core 3 of the board. On underside 8 of the board, which faces away from decorative ...

Abstract

The invention relates to a directly laminated plate or board that is produced by hot-pressing a core with absorbent, resin-impregnated layers, wherein at least one board surface has a decorative layer with a graphic representation of the surface of an imitated material, in addition to a resin-impregnated, transparent cover layer on said decorative layer, with a relief-like reproduction of the surface structure of the imitated material, where a resinous intermediate ply is provided between the decorative layer and the core.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 10 / 513,773, filed Sep. 14, 2005, which is a U.S. national stage application of PCT / DE03 / 01207, filed Apr. 11, 2003, which claim priority to German application no. 102 20 501.9, filed May 7, 2002, the entire disclosures of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates to a directly laminated plate or board that is produced by hot-pressing a core and absorbent, resin-impregnated layers, wherein at least one board surface has a decorative layer with a graphic representation of the surface of an imitated material, in addition to a resin-impregnated, transparent cover layer on said decorative layer, with a relief-like reproduction of the surface structure of the imitated material.BACKGROUND OF THE PRIOR ART[0003]Imitated materials include, for example, building materials, such as wood, ceramics, natural stone and artificial sto...
