Method for producing a building panel
A method for producing a building panel. The method includes forming a mix including wood particles, a solvent, a binder and optionally at least one additive, wherein the binder and optionally said at least one additive are homogenously distributed in the mix by means of the solvent and wherein the binder impregnates the wood particles, drying the mix, applying the mix on a substrate, and forming a layer by applying heat and pressure to the mix.
1. A method for producing a building panel, comprising
forming a mix comprising wood particles, a solvent, a binder and at least one pigment, wherein the binder and said at least one pigment are homogenously distributed in the mix by means of the solvent and wherein the binder impregnates and binds to the wood particles, thereby forming granulates, the granulate being formed by a wood particle, binder and pigment,
drying the mix to form a dried mix,
applying the dried mix on a substrate, and
forming a building panel by applying heat and pressure to the dried mix, the building panel comprising the substrate and a dried mix layer.
2. The method according to claim 1 , wherein the dried mix forms at least part of a decorative surface layer.
3. The method according to claim 1 , wherein the step of forming the mix comprises adding the solvent to a mix of the wood particles, the binder and said at least one pigment.
4. The method according to claim 1 , wherein the step of forming the mix comprises mixing the wood particles with the solvent comprising the binder and said at least one pigment.
5. The method according to claim 1 , wherein the mix further comprises wear resistant particles.
6. The method according to claim 5 , wherein the wear resistant particles are aluminium oxide.
7. The method according to claim 1 , wherein the substrate is a core.
8. The method according to claim 7 , wherein the core is a wood-based core.
9. The method according to claim 8 , wherein the wood-based core is MDF, HDF, OSB, WPC or particle board.
10. The method according to claim 1 , wherein the substrate is a decorative layer.
11. The method according to claim 1 , wherein the step of applying the dried mix on the substrate comprises applying the dried mix on an additional layer formed of wood particles and a dry binder, the additional layer being on the substrate.
12. The method according to claim 1 , wherein the method further comprises forming an additional layer over said dried mix layer, such that said dried mix layer forms a sub-layer.
13. The method according to claim 12 , wherein the additional layer is formed on the dried mix prior to the step of forming the building panel.
14. The method according to claim 1 , further comprising printing a print in the dried mix.
15. The method according to claim 14 , wherein the printing is a digital printing.
16. The method according to claim 1 , wherein the step of forming and/or drying the mix is performed under vacuum.
17. The method according to claim 1 , wherein the mix further comprises at least one additive.
18. The method according to claim 17 , wherein said at least one additive is a wetting agent, a release agent, a catalyst, an antistatic agent, a curing agent, a foaming agent, a coupling agent, a plasticizer or a compatibilizer.
19. The method according to claim 1 , wherein the binder is a thermosetting resin.
20. The method according to claim 18 , wherein the binder is an amino resin.
21. The method according to claim 18 , wherein the binder is melamine formaldehyde resin.
22. The method according to claim 1 , wherein the binder is a thermoplastic resin.
23. The method according to claim 1 , wherein the wood particles are recycled, virgin or processed.
24. The method according to claim 1 , wherein the solvent is water, a glycol, a polyol or an alcohol.
25. The method according to claim 1 , wherein the dried mix is applied directly on the substrate.
26. A method for producing a building panel, comprising
applying a dried mix on a core, and
forming a building panel by applying heat and pressure to the dried mix,
wherein the dried mix is formed by drying a mix comprising wood particles, a solvent, a binder and at least one pigment, wherein the binder, and said at least one pigment, are homogenously distributed in the mix by means of the solvent and wherein the binder impregnates and binds to the wood particles, thereby forming granulates, the granulate being formed by a wood particle, binder and pigment.
