Abstract

A floor, wall, or ceiling panel and to a method for producing same. The panel has a base made of a wood material and an upper veneer. The base and the veneer are hot-pressed together while incorporating a resin layer. During the pressing process, pores, cracks, and/or gaps in the veneer are filled with resin. In particular, the pressing process is carried out such that the veneer is saturated with resin, and the resin can be seen on the surface of the veneer after the pressing process. The adhesion of the veneer to the base and the smoothing of the veneer are thus carried out in one operation.

First claim

The invention claimed is:

1. A method for producing panels, said method comprising:
providing a basic carrier plate, the basic carrier plate comprising a top surface and a bottom surface;
providing a veneer;
applying a resin layer on the top surface of the basic carrier plate;
forming a multilayer body comprising the basic carrier plate, the veneer, the resin layer interposed between the basic carrier plate and the veneer; and
joining the basic carrier plate, the resin layer, and the veneer, by pressing the multilayer body in a press,
wherein the pressing of the multilayer body is carried out so that the resin impregnates the veneer, and
wherein the pressing is performed at a pressing pressure greater than or equal to 1000 kPA.

2. The method of claim 1 , wherein a pressing time is between 10 seconds and 60 seconds.

3. The method of claim 1 , further comprising:
separating the pressed multilayer body into individual panels; and
profiling the panels at side borders of the panels and providing the panels with joining means.

4. The method of claim 1 , wherein the veneer includes pores, cracks, and/or gaps.

5. The method of claim 1 , wherein a pressing pressure, a pressing temperature and a pressing time are adjusted so that during the pressing of the multilayer body in the press, the pores, the cracks, and/or the gaps in the veneer are filled with resin from the resin layer.

6. The method of claim 1 , further comprising providing a balancing layer arranged on the bottom surface of the basic carrier plate.

7. The method of claim 1 , wherein the resin layer is applied as a powder, a paste, a resin film, or a watery resin solution.

8. The method of claim 1 , wherein resin layer comprises filler.

9. The method of claim 1 , wherein the veneer is a soft wood veneer, wherein after pressing and impregnation of the veneer, the soft wood veneer becomes harder.

10. A method for producing panels, said method comprising:
providing a basic carrier plate, the basic carrier plate comprising a top surface and a bottom surface;
providing a veneer;
applying a resin layer on the top surface of the basic carrier plate;
forming a multilayer body comprising the basic carrier plate, the veneer, the resin layer interposed between the basic carrier plate and the veneer; and
joining the basic carrier plate, the resin layer, and the veneer, by pressing the multilayer body in a press,
wherein the pressing of the multilayer body is carried out so that the resin impregnates the veneer, and
the press plate is heated to a temperature of between 180° C. and 210° C. during the pressing in the press.

11. The method of claim 10 , wherein a pressing time is between 10 seconds and 60 seconds.

12. The method of claim 10 , further comprising:
separating the pressed multilayer body into individual panels; and
profiling the panels at side borders of the panels and providing the panels with joining means.

13. The method of claim 10 , wherein the veneer includes pores, cracks, and/or gaps.

14. The method of claim 10 , wherein a pressing pressure, a pressing temperature and a pressing time are adjusted so that during the pressing of the multilayer body in the press, the pores, the cracks, and/or the gaps in the veneer are filled with resin from the resin layer.

15. The method of claim 10 , further comprising providing a balancing layer arranged on the bottom surface of the basic carrier plate.

16. The method of claim 10 , wherein the resin layer is applied as a powder, a paste, a resin film, or a watery resin solution.

17. The method of claim 10 , wherein resin layer comprises filler.

18. The method of claim 10 , wherein the veneer is a soft wood veneer, wherein after pressing and impregnation of the veneer, the soft wood veneer becomes harder.

19. The method of claim 1 , wherein the resin layer is applied as a powder.

20. The method of claim 10 , wherein the resin layer is applied as a powder.
