Abstract

A paper for a laminate panel includes a first layer that includes a resin impregnated decorative paper or a resin impregnated overlay; and a second layer of abrasion resistant particles uniformly distributed on and adhered to the first layer.

Claims (16)

1. A paper for a laminate panel comprising:

a first layer comprising a resin impregnated decorative paper or a resin impregnated overlay, the resin comprising a melamine resin or an urea resin or a mixture of both; and

a second layer of abrasion resistant particles uniformly distributed on and adhered to the first layer, wherein the abrasion resistant particles have an outer coating consisting of an amino-silane adhesion promoter, the outer coating formed by coating the abrasion resistant particles with a liquid consisting of the amino-silane adhesion promoter, and then drying the coated abrasion resistant particles to form the outer coating on the abrasion resistant particles,

wherein the abrasion resistant particles with the outer coating thereon are applied to the first layer after drying the coated abrasion resistant particles.

2. The paper according to claim 1 , wherein the abrasion-resistant particles have a diameter of 50 to 200 μm.

3. The paper according to claim 1 , wherein the abrasion-resistant particles are made of silicon carbide or aluminum oxide.

4. The paper according to claim 1 , wherein the decorative paper has a weight of 20 to 60 g/m 2 .

5. The paper according to claim 4 , wherein the decorative paper is filled with an acrylate.

6. The paper according to claim 1 , wherein the abrasion resistant particles lie in a plane.

7. The paper according to claim 1 , wherein the resin contains an amino resin and a further resin, and the paper is provided with a decor.

8. The paper according to claim 2 , wherein the abrasion-resistant particles have a diameter of 90 to 130 μm.

9. The paper according to claim 7 , wherein the first layer comprises a decorative paper and the paper further comprises a third layer overlying the second layer comprising an overlay or fibers, and the overlay or the fibers are impregnated with a pure amino resin.

10. The paper according to claim 1 wherein the abrasion resistant particles comprise corundum.

11. A laminate panel comprising the paper according to claim 1 , applied on a baseboard made of a derived timber product.

12. The laminate panel according to claim 11 , comprising coupling elements disposed along opposite longitudinally extending edges and opposite transversely extending edges, so that the laminate panel can be connected to another like laminate panel both in a transverse and longitudinal direction relative to the surface of the panel.

13. The laminate panel according to claim 11 , comprising a backing paper provided with a urea resin.
