Non-flammable panel with real wood veneer and method of manufacture

Abstract

The invention relates to a non-flammable panel with real wood veneer and a method for manufacturing such a panel. The non-flammable panel is characterized by a non-flammable carrier board and a thin real wood veneer which was laminated onto the carrier board by means of a mineral glue.

Claims

1. A panel comprising a non-flammable carrier board which is laminated at least on one side with a wood veneer as a visible real wood surface, wherein the wood veneer has a thickness of less than 0.5 mm and is laminated by means of a mineral glue onto the non-flammable carrier board, the mineral glue is a water glass, and the carrier board is a gypsum-based carrier board, a cement-bound panel or a calcium silicate panel.

2. The panel according to claim 1, wherein the wood veneer is printed at least in certain areas.

3. The panel according to claim 1, wherein the wood veneer is printed by means of multi-coloured digital printing.

4. The panel according to claim 2, wherein the wood veneer with or without print, is covered at least in certain areas by a top-coat lacquer.

5. The panel according to claim 1, wherein the panel conforms to a building material class A2.

6. The panel according to claim 5, wherein the panel conforms to a fire safety class A2 s1-d0 according to EN 13501-1.

7. The panel according to claim 1, wherein the gypsum-based carrier board is a gypsum fibre board or a concrete panel.

Description

(1) The invention is explained in detail hereinafter with reference to two specific exemplary embodiments.

(2) FIG. 1 shows a non-flammable panel which was laminated with a 0.3 mm thick beech wood veneer and covered with a top-coat lacquer. The beech wood veneer was laminated in a thickness of 0.6 mm by means of a K-water glass glue onto a gypsum fibre board having a density of 1100 kg/m.sup.3 and a thickness of 12 mm whilst applying pressure and temperature.

(3) The wood veneer was polished to a thickness of 0.3 mm after drying of the water glass glue and covered with a top-coat lacquer. The panel can be used as a floor, wall or ceiling panel.

(4) FIG. 2 shows a panel produced as described in FIG. 1 which however was printed in certain areas after the polishing and before application of the top-coat lacquer. The printing with a darker colour than the natural wood colour makes it possible to produce a panel having a more vibrant visual appearance than the natural panel. A water-based ink was used for the applied digital print.
