Abstract

Building panels and a method to produce such panels including a solid decorative surface having a decorative wear layer including fibres, binders, colour substance and wear resistant particles.

Claims

1. A building panel comprising a decorative surface connected to a core wherein the surface comprises at least two substantially homogenous layers, a lower sub layer and an upper decorative layer, wherein the upper decorative layer comprises fibres, a first colour substance, a binder and wear resistant particles and the sub layer comprises fibres, a binder and a second colour substance, the first and a second colour substance are different colours and particles or portions comprising the second colour substance are located on the upper parts of the upper decorative surface layer.

2. The building panel as claimed in claim 1, wherein the panel is a floor panel.

3. The building panel as claimed in claim 1, wherein the second layer comprises wear resistant particles.

4. The building panel as claimed in claim 1, wherein the core is a HDF board.

5. The building panel as claimed in claim 1, wherein the first colour substance comprises colour pigments and wood fibres and wherein the second colour substance comprises colour pigments and wood fibres.

6. The building panel as claimed in claim 1, wherein the first colour substance comprises a colour pigment and wherein the second colour substance comprises a colour pigment.

7. The building panel as claimed in claim 2, wherein the core is a HDF board.

8. The building panel as claimed in claim 3, wherein the core is a HDF board.

9. The building panel as claimed in claim 2, wherein the first colour substance comprises colour pigments and wood fibres and wherein the second colour substance comprises colour pigments and wood fibres.

10. The building panel as claimed in claim 3, wherein the first colour substance comprises colour pigments and wood fibres and wherein the second colour substance comprises colour pigments and wood fibres.

11. The building panel as claimed in claim 4, wherein the first colour substance comprises colour pigments and wood fibres and wherein the second colour substance comprises colour pigments and wood fibres.

12. A method of manufacturing a building panel having a decorative surface connected to a core wherein the surface comprises at least two homogenous layers, a lower sub layer and an upper decorative layer, the upper decorative layer comprising fibres, a first colour substance a binder and wear resistant particles, the lower sub layer comprising fibres, a second colour substance, and a binder, whereby the method comprises the steps of:

applying the layers comprising a mix of fibres, binder, wear resistant particles and colour substance on a core wherein the layers comprise different colours;

displacing particles from their original position such that particles from the sub layer are visible on the decorative surface; and

curing the layers by providing heat and pressure.

13. The method as claimed in claim 12, wherein the panel is a floor panel.

14. The method as claimed in claim 12, wherein the core is a HDF board.

15. The method as claimed in claim 12, wherein the colour substance comprises colour pigments and wood fibres.

16. The method as claimed in claim 12, wherein the first colour substance comprises a colour pigment and wherein the second colour substance comprises a colour pigment.

17. The method as claimed in claim 13, wherein the core is a HDF board.

18. The method as claimed in claim 13, wherein the colour substance comprises colour pigments and wood fibres.

19. The method as claimed in claim 14, wherein the colour substance comprises colour pigments and wood fibres.
