Method to produce a thermoplastic wear resistant foil
A method to produce a wear resistant foil, including providing a first foil including a first thermoplastic material, applying wear resistant particles on the first foil, applying a second foil including a second thermoplastic material on the first foil, and adhering the first foil and the second foil to each other to form a wear resistant foil.
1. A method to produce a building panel, comprising
providing a core,
applying a first foil comprising a first thermoplastic material on the core,
applying a second foil comprising a second thermoplastic material on a side of the first foil opposite to a side of the first foil applied to the core,
applying wear resistant particles on the first foil and/or on the second foil prior to applying the second foil on the first foil, and
adhering the core, the first foil and the second foil to each other to form the building panel, wherein all off the wear resistant particles do not protrude from a surface of the second foil opposite the first foil.
2. The method according to claim 1 , wherein the wear resistant particles are enclosed by the first and the second foils after the second foil is applied to the first foil.
3. The method according to claim 1 , wherein the first thermoplastic material comprises polyvinyl chloride (PVC).
4. The method according to claim 1 , wherein the second thermoplastic material comprises polyurethane (PU).
5. The method according to claim 1 , wherein the first thermoplastic material comprises polyvinyl chloride (PVC), polyester, polypropylene (PP), polyethylene (PE), polystyrene (PS), polyurethane (PU), polyethylene terephthalate (PET), polyacrylate, methacrylate, polycarbonate, polyvinyl butyral, polybutylene terephthalate, or a combination thereof.
6. The method according to claim 1 , wherein the second thermoplastic material comprises polyvinyl chloride (PVC), polyester, polypropylene (PP), polyethylene (PE), polystyrene (PS), polyurethane (PU), polyethylene terephthalate (PET), polyacrylate, methacrylate, polycarbonate, polyvinyl butyral, polybutylene terephthalate, or a combination thereof.
7. The method according to claim 1 , wherein the wear resistant particles comprise aluminum oxide.
8. The method according to claim 1 , wherein the wear resistant particles have an average particle size of less than 45 μm.
9. The method according to claim 1 , wherein the core, the first foil and the second foil are adhered to each other by pressing.
10. The method according to claim 9 , wherein a thickness of the second foil is less than 75 μm after pressing.
11. The method according to claim 1 , wherein the wear resistant particles are applied on the first foil.
12. The method according to claim 1 , wherein the second foil is formed by an extrusion process.
13. The method according to claim 1 , wherein the first foil, the second foil and the wear resistant particles form a wear resistant foil which is substantially transparent.
14. The method according to claim 1 , wherein the core comprises a third thermoplastic material.
15. The method according to claim 14 , wherein the third thermoplastic material comprises polyvinyl chloride (PVC), polyester, polypropylene (PP), polyethylene (PE), polystyrene (PS), polyurethane (PU), polyethylene terephthalate (PET), polyacrylate, methacrylate, polycarbonate, polyvinyl butyral, polybutylene terephthalate, or a combination thereof.
16. The method according to claim 1 , wherein the core is a wood-based board, a wood plastic composite (WPC), a thermoplastic board or a mineral board.
17. The method according to claim 1 , further comprising arranging a decorative layer on the core.
18. A method to produce a building panel, comprising
providing a core,
applying a foil comprising a thermoplastic material on the core,
applying wear resistant particles on the core and/or on the foil prior to the foil being applied on the core, and
adhering the core and the foil together to form a building panel, wherein all off the wear resistant particles do not protrude from a surface of the foil opposite a surface of the foil applied on the core.
19. The method according to claim 18 , wherein the wear resistant particles are enclosed by the foil and the core.
20. The method according to claim 18 , wherein the thermoplastic material comprises polyvinyl chloride (PVC), polyester, polypropylene (PP), polyethylene (PE), polystyrene (PS), polyurethane (PU), polyethylene terephthalate (PET), polyacrylate, methacrylate, polycarbonate, polyvinyl butyral, polybutylene terephthalate, or a combination thereof.
21. The method according to claim 20 , wherein the wear resistant particles have an average particle size of less than 45 μm.
22. The method according to claim 20 , wherein
the core and the foil are adhered to each other by pressing and a thickness of the foil is less than 75 μm after pressing.
23. The method according to claim 20 , wherein the core and the foil are adhered to each other by pressing.
24. The method according to claim 20 , wherein the wear resistant particles are applied on the core.
25. The method according to claim 20 , wherein the foil is formed by an extrusion process.
26. The method according to claim 18 , wherein the core is a thermoplastic core, a wood plastic composite (WPC), a wood-based board or a mineral board.
