Abstract

A derived timber board with a surface coating applied at least in parts is characterized in that at least one coating of a synthetic resin reinforced with fibres is applied as a surface coating. A method for applying the coating is also described.

Claims

1. A derived timber board with a surface coating applied at least in parts, said applied coating including at least one coating of a synthetic resin applied in a liquid state and reinforced with fibres.

2. The derived timber board according to claim 1, wherein the fibre-reinforced synthetic resin coating comprises a thermosetting synthetic resin.

3. The derived timber board according to claim 2, wherein the thermosetting synthetic resin is an aminoplastic.

4. The derived timber board according to claim 2, wherein the thermosetting synthetic resin is a melamine resin.

5. The derived timber board according to claims 1, wherein said fibres are selected form the group consisting of cellulose fibres, viscose fibres, synthetic fibres, fibres made of glass, fibres made of ceramic, and mixtures thereof.

6. The derived timber board according to claim 1, wherein said fibres are present in a concentration of at least 5 weight percent with reference to a weight of the synthetic resin.

7. The derived timber board according to claim 6, wherein the concentration is in the range of from 5 to 40 weight percent.

8. The derived timber board according to claim 6, wherein the concentration is in the range of from 5 to 20 weight percent.

9. The derived timber board according to claim 1, wherein the fibres are transparent after the synthetic resin has cured.

10. The derived timber board according to claim 1, wherein the at least one synthetic resin coating reinforced with fibres contains corundum.

11. The derived timber board according to claim 1, wherein the at least one fibre-reinforced synthetic resin coating is a component of a multi-layered surface coating.

12. A method for applying a liquid synthetic resin-fibre mixture to a derived timber board, comprising the steps of:

mixing fibres into a liquid synthetic resin;

painting, rolling, pouring or spraying the synthetic resin or using a squeegee to apply the synthetic resin-fibre mixture to the derived timber board; and

drying the synthetic resin-fibre mixture.

13. The method according to claim 12, wherein said mixing step comprises mixing fibres of up to 40 weight percent with reference to the weight of the synthetic resin into the synthetic resin.

14. The method according to claim 12, wherein the drying step comprises drying the synthetic resin-fibre mixture in a plurality of stages.
