Fibre based panels with a wear resistance surface
View Patent ↗Building panels with a homogenous decorative surface having a wear layer including fibers, binders and wear resistant particles.
1. A method of manufacturing a building panel comprising the steps of:
mechanically mixing wood fibres with a binder and wear resistant particles into a mix; and
bringing the mix, including the wood fibres, the binder and the wear resistant particles, under heat and pressure, thereby forming a building panel.
2. The method as claimed in claim 1 , wherein the building panel is a floor panel.
3. The method as claimed in claim 1 , wherein the binder is a thermoplastic resin.
4. The method as claimed in claim 1 , wherein the binder is a thermosetting resin.
5. The method as claimed in claim 1 , wherein the wear resistant particles comprise aluminium oxide.
6. The method as claimed in claim 1 , wherein the method further comprises the step of applying the mix on a core comprising a wood fibre based board.
7. The method as claimed in claim 6 , wherein the wood fibre based board is HDF.
8. The method as claimed in claim 6 , wherein the wood fibre based board is a particleboard.
9. The method as claimed in claim 1 , wherein the method further comprises a pre pressing prior to the final pressing.
10. The method as claimed in claim 1 , wherein the method further comprises a printing operation prior to the final pressing.
11. The method as claimed in claim 1 , wherein the method comprises a machining operation comprising forming the building panel to a floor panel with mechanical locking systems at opposite edges.
12. A method as claimed in claim 1 , wherein the method further comprises the steps of:
arranging the mix on a core layer comprising wood fibres and a binder;
arranging said core layer on a balancing layer comprising wood fibres and a binder; and
applying heat and pressure to the three layers comprising the mix, the core and the balancing layer.
13. The method as claimed in claim 12 wherein the balancing layer has a higher density than the core layer.
14. The method as claimed in claim 12 , wherein the binder is a thermosetting resin and the wear resistant particles comprise aluminium oxide.
15. The method as claimed in claim 1 , wherein the wood fibres, the binder, and the wear resistant particles are in dry form.
16. The method as claimed in claim 1 , wherein the mix is in powder form.
17. The method as claimed in claim 1 , wherein the step of mixing comprises mixing the mix into a homogenous mix.
18. The method as claimed in claim 1 , wherein the mix further comprises colour pigments.
19. The method as claimed in claim 6 , wherein the mix forms a surface layer on said core.
20. The method as claimed in claim 10 , wherein the printing operation is performed by an ink jet printer.
21. The method as claimed in claim 1 , wherein the wood fibres are in powder form.
22. A method of manufacturing a building panel comprising the steps of:
mixing wood fibres with a binder and wear resistant particles into a mix,
applying the mix on a core, and
bringing the mix, including the fibres, the binder and the wear resistant particles, under heat and pressure, thereby the mix forms a surface layer on the core.
23. A method of manufacturing a building panel comprising the steps of:
mechanically mixing fibres with a binder and wear resistant particles into a mix, and
bringing the mix, including the fibres, the binder and the wear resistant particles, under heat and pressure, thereby forming a building panel.
