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