METHOD FOR FINISHING A BUILDING BOARD AND BUILDING BOARD

Abstract

A method for finishing a building board, in particular a wood material or plastic board or a mixture of wood material and plastic. The building board includes a top side and an underside and opposite side edges. The method includes embossing a structure and/or a relief in at least the top side of the building board. A pattern is applied to the embossed side of the building board. The pattern is sealed by the application of an abrasion-resistant layer to the pattern.

Claims

1. A method for finishing a building board with a top side and an underside and opposite side edges, comprising: embossing at least one of a structure and a relief in at least the top side of the building board;applying a pattern to the embossed at least the top side of the building board; andsealing of the pattern by applying an abrasion-resistant layer to the pattern.

2. The method according to claim 1, wherein the building board is heated to a temperature of about 40-150° C. before the embossing.

3. The method according to claim 1, wherein the building board is cooled to a temperature of about 20-40° C. after the embossing.

4. The method according to claim 1, wherein the pattern, the structure and the relief coincide so that a natural material is imitated.

5. The method according to claim 1, wherein at least the top side is smoothed by pressing or sanding before the embossing.

6. The method according to claim 1, wherein the building board is either a MDF or HDF board, or an MDF or at least one of HDF board produced by a 2-glue system and an HDF or MDF board embodied with a soft cover layer that cures during processing.

7. The method according to claim 1, wherein the building board is a chipboard coated with an ashfree paper that can be impregnated and comprises long-fiber a cellulose with a grammage of 10 to 20 g/m2.

8. The method according to claim 1, wherein the building board is a chipboard coated with an ashfree paper that can be impregnated and comprises long-fiber a cellulose with a grammage of 12 g/m2.

9. The method according to claim 1, wherein the building board is an OSB board that has a smoothed surface.

10. The method according to claim 1, wherein the building board is a plastic board of recycling plastics with a wood content.

11. The method according to claim 1, wherein the embossing takes place by a press belt in a feed-through press.

12. The method according to claim 1, wherein the embossing is carried out by at least one pressing plate in a short-cycle press.

13. The method according to claim 1, wherein the embossing is carried out by a roller in a calender installation.

14. The method according to claim 11, wherein an embossed structure of a pressing plate and a structure of a pattern roller are coordinated with one another.

15. The method according to claim 1, wherein the pattern is applied by printing rollers.

16. The method according to claim 1, wherein the pattern is applied by digital printing.

17. The method according to claim 1, wherein the pattern is applied as a powder coating.

18. The method according to one claim 14, wherein alignment of the building board to the pressing plate and to the pattern roller takes place via at least two reference points at or on the building board.

19. The method according to claim 1, further comprising applying an abrasion-resistant layer, a varnish that is electron-beam cured or a melamine resin coating with or without abrasion-resistant particles.

20. The method according to claim 1, further comprising applying a UV-curable varnish as an abrasion-resistant layer.

21. The method according to claim 1, further comprising applying a polyurethane coating or a powder paint as an abrasion-resistant layer.

22. The method according to claim 1, wherein connecting mechanisms corresponding to one another and are embodied on opposite side edges of the building board.

23. The method according to claim 22, wherein the connecting mechanisms are provided with locking elements for mechanical locking of at least two building boards to one another.

24. The method according to claim 1, further comprising applying a paper layer to the top side before the embossing.

25. The method according to claim 1, further comprising applying light papers to the top side before the embossing.

26. The method according to claim 1, wherein the building board is composed of a wood material, plastic or a mixture of wood material and plastic.

27. The method according to claim 1, wherein the building board is at least one of paneling for walls, floors and ceilings and as a furniture front.

28. A building board comprising: at least one of a structure and a relief embossed in a top side of the building board;a pattern applied over the embossed the top side of the building board; anda sealing layer sealing the pattern.

29. The building board of claim 28, wherein the sealing layer is an abrasion-resistant layer.

30. The building board according to claim 28, wherein the top side is smooth.

31. The building board according to claim 28, wherein the building board is either a MDF or HDF board, or an MDF or at least one of HDF board produced by a 2-glue system and an HDF or MDF board embodied with a soft cover layer that cures during processing.

32. The building board according to claim 28, wherein the building board is a chipboard coated with an ashfree paper that can be impregnated and comprises long-fiber a cellulose with a grammage of 10 to 20 g/m2.

33. The building board according to claim 28, wherein the building board is an OSB board that has a smoothed surface.
