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.

First claim

What is claimed:

1. A method for finishing a building board having a top side, an underside and opposite side edges, comprising:
embossing at least one of a structure and a relief into the at least top side of the building board;
applying a pattern to the embossed at least the top side of the building board; and
sealing of the pattern, after curing of the pattern, wherein by applying an abrasion-resistant layer to the pattern, which is a varnish that is electron-beam cured or a melamine resin coating with or without abrasion-resistant particles,
the building board is heated to a temperature of about 40-150° C. before the embossing; and
the building board is a chipboard coated with an ashfree paper that is impregnated and comprises long-fiber a cellulose with a grammage of 10 to 20 g/m 2 , the ashfree paper being applied the top side of the building board prior to the embossing,
the embossing takes place by a press belt in a feed-through press.

2. The method according to claim 1 , wherein the pattern and the at least one of the structure and the relief coincide so that a natural material is imitated.

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

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

5. 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.

6. The method according to claim 1 , wherein the pattern is applied by ink printing after the embossing.

7. The method according to claim 1 , wherein the building board is chipboard coated with the ashfree paper that is impregnated and comprises long-fiber the cellulose with a grammage of 12 g/m 2 .

8. The method according to claim 1 , wherein the at least one of the structure and the relief are directly embossed into the chipboard with the ashfree paper.

9. A method for finishing a building board having a top side, an underside and opposite side edges, comprising:
embossing at least one of a structure and a relief into the at least top side of the building board;
applying a pattern to the embossed at least the top side of the building board; and
sealing of the pattern, after curing of the pattern, by applying an abrasion-resistant layer to the pattern with or without abrasion-resistant particles, wherein:
the building board is heated to a temperature of about 40-150° C. before the embossing; and
the building board is a chipboard coated with an ashfree paper that is impregnated and comprises long-fiber a cellulose with a grammage of 10 to 20 g/m 2 , the ashfree paper being applied the top side of the building board prior to the embossing,
the embossing takes place by a press belt in a feed-through press.

10. The method according to claim 9 , wherein the abrasion-resistant layer is a varnish that is electron-beam cured or that is UV cured.

11. The method according to claim 9 , wherein the abrasion-resistant layer is a polyurethane coating or a melamine resin coating.

12. The method according to claim 9 , wherein the pattern is applied by digital printing.
