Abstract

The solution of the problem is arrived at through the following steps: a) applying liquid resin to the top side, b) drying the resin, c) pressing the construction plate under the influence of temperature, so that the resin at least partially melts, wherein the pressing may be performed in a continuous press.

Claims (48)

1. A process for sealing a construction plate of wood or a wood material, having a top side and a bottom side, with the following steps:

applying multiple layers of a liquid resin on the top side,

drying the resin,

pressing the construction plate under the influence of temperature so that the resin at least partially melts, wherein the pressing is performed in a continuous press, and

embossing a relief matching a pattern of a wood grain into the resin layer on pressing.

2. The process according to claim 1 , further comprising the following steps:

application of the resin to the bottom side,

drying the resin,

pressing the construction plate under the influence of temperature so that the resin at least partially melts.

3. The process of claim 2 , further comprising mixing fillers into the resin on the bottom side for improving impact sound characteristics of a floor board made from the plate.

4. The process according to claim 1 , wherein an applied one of the multiple layers is dried before a next one of the multiple layers is applied.

5. The process according to claim 1 , wherein the resin is a synthetic resin.

6. The process according to claim 5 , wherein the synthetic resin is a melamine resin.

7. The process according to claim 1 , wherein the resin is stained.

8. The process according to claim 1 , further comprising applying a color layer between the resin layers.

9. The process of claim 8 , wherein:

the color layer is printed with a wood grain pattern, and

the pressing embosses the relief matching the wood grain pattern into the resin.

10. The process according to claim 1 , wherein corundum is mixed into or scattered onto individual layers of the multiple layers.

11. The process according to claim 2 , wherein the resin is applied simultaneously on the top side and the bottom side.

12. The process of claim 1 , wherein the construction plate comprises solid wood.

13. A process for sealing a plate of wood, the plate having a top side and a bottom side, the process comprising:

simultaneously coating the top side and the bottom side with resin;

drying the resin;

pressing the plate under the influence of temperature so that the resin at least partially melts, wherein the pressing is performed in a continuous press; and

applying a color layer between the resin and at least one of the top side and the bottom side,

wherein the color layer is printed with a wood grain pattern and the pressing embosses a relief matching the wood grain pattern into the resin.

14. The process of claim 13 , wherein:

the resin is stained to produce a visual effect,

corundum particles are mixed into or scattered onto the resin, and

the plate is solid wood.

15. The process of claim 13 , further comprising mixing fillers into the resin on the bottom side for improving impact sound characteristics of a floor board made from the plate.

16. A process for sealing a plate of wood or wood material, the plate having a top side and a bottom side, the process comprising:

applying multiple layers of a synthetic liquid resin on the top side, wherein an applied one of the multiple layers is dried before a next one of the multiple layers is applied on the top side;

applying multiple layers of the synthetic liquid resin on the bottom side, wherein an applied one of the multiple other layers is dried before a next one of the multiple other layers is applied to the bottom side;

pressing, in a continuous press, the plate under the influence of temperature so that the synthetic liquid resin at least partially melts;

embossing a relief matching a pattern of wood grain in the synthetic liquid resin; and

applying a color layer between the synthetic liquid resin layers on the top side, the color layer being printed with the wood grain pattern, wherein:

the synthetic liquid resin is stained to produce a visual effect,

corundum particles are mixed or sprinkled onto individual layers of the multiple layers of the synthetic liquid resin on the top side,

mixing fillers into the layers of synthetic liquid resin on the bottom side for improving impact sound characteristics of a floor board made from the plate; and

the multiple layers of the synthetic liquid resin are applied simultaneously on the top side and the bottom side.

17. The process of claim 16 , wherein the applying the color layer is a printing process.

18. The process of claim 17 , wherein the plate of wood is OSB and prior to the applying multiple layers of the synthetic liquid resin on the top side and the bottom side, smoothing the OSB to eliminate unevenness.

19. The process of claim 18 , wherein the pressing forms a glossy or reflective surface on the plate.

20. The process of claim 19 , wherein the synthetic liquid resin is melamine.

21. The process of claim 17 , wherein the plate is solid wood.

22. The process of claim 21 , wherein the pressing forms a glossy or reflective surface on the plate.
