Fibre based panels with a decorative wear resistance surface
View Patent ↗A method to produce building panels is disclosed which method includes the step of applying a layer ( 5 ) comprising a mix of fibers ( 14 ), binder ( 12 ), and wear resistant particles ( 12 ) on a carrier ( 6 ), pressing the layer ( 5 ) with an embossed matrix ( 2 a, 2 b ) and providing embossed portions ( 4 ) and filling the embossed portions with decorative a substance ( 3 ).
1. A method of manufacturing a building panel comprising the steps of:
applying a layer comprising a mix of fibres, binder, and wear resistant particles on a carrier;
pressing the layer with an embossed matrix and providing embossed portions; and
after pressing, and in a separate step, filling the embossed portions with a decorative substance.
2. The method as claimed in claim 1 , wherein the panel is a floor panel.
3. The method as claimed in claim 1 , the step further comprising an additional pressing that is made after filling of the embossed portions.
4. The method as claimed in claim 1 , wherein the carrier is a HDF board.
5. The method as claimed in claim 1 , wherein the decorative substance comprises wear resistant particles and a binder.
6. The method as claimed in claim 1 , wherein the decorative substance comprises colour pigments and wood fibres.
7. The method as claimed in claim 2 , wherein the carrier is a HDF board.
8. The method as claimed in claim 3 , wherein the carrier is a HDF board.
9. The method as claimed in claim 5 , wherein the wear resistant particles of the decorative substance are aluminium oxide particles.
10. The method as claimed in claim 2 , where the decorative substance comprises wear resistant particles.
11. The method as claimed in claim 10 , wherein the wear resistant particles of the decorative substance are aluminium oxide particles.
12. The method as claimed in claim 3 , where the decorative substance comprises wear resistant particles.
13. The method as claimed in claim 12 , wherein the wear resistant particles of the decorative substance are aluminium oxide particles.
14. The method as claimed in claim 4 , where the decorative substance comprises wear resistant particles.
15. The method as claimed in claim 14 , wherein the wear resistant particles of the decorative substance are aluminium oxide particles.
16. The method as claimed in claim 1 , wherein the wear resistant particles are aluminium oxide particles.
17. A method of manufacturing a building panel comprising the steps of:
applying a layer comprising a mix of fibres, binder, and wear resistant particles on a carrier;
pressing the layer with an embossed matrix and providing an embossed portion; and
filling the entirety of the volume of the embossed portion with a decorative substance.
18. A method of manufacturing a building panel comprising the steps of:
applying a layer comprising a mix of fibres, binder, and wear resistant particles on a carrier;
pre-pressing the layer with an embossed matrix and providing embossed portions;
filling the embossed portions with a decorative substance; and
curing the layer under heat and pressure.
19. The method of claim 18 , wherein the filling step comprises filling the entirety of the volume of the embossed portion with a decorative substance.
20. The method of claim 19 , wherein the cured layer is flat across the embossed portion.
21. A method of manufacturing a building panel comprising the steps of:
applying a layer comprising a mix of fibres, binder, and wear resistant particles on a carrier;
pressing the layer with an embossed matrix and providing embossed portions; and
filling the embossed portions with a powdered colour pigment in a dry form.
22. A method of manufacturing a building panel comprising the steps of:
applying a layer comprising a mix of fibres, binder, and wear resistant particles on a carrier;
pressing the layer with an embossed matrix and providing embossed portions; and
filling the embossed portions with a decorative substance, by applying the decorative substance by scattering combined with vibration.
23. The method as claimed in claim 1 , where the decorative substance comprises wear resistant particles.
24. The method as claimed in claim 23 , wherein the decorative substance further comprises a color pigment.
25. The method as claimed in claim 17 , where the decorative substance comprises wear resistant particles.
26. The method as claimed in claim 18 , where the decorative substance comprises wear resistant particles.
27. The method as claimed in claim 21 , where the decorative substance comprises wear resistant particles.
28. The method as claimed in claim 22 , where the decorative substance comprises wear resistant particles.
