Covering and method for producing coverings
The current invention concerns coverings such as a floor covering, wall covering or ceiling covering, said covering comprising at least one substrate and at least one surface layer, said surface layer comprising a print pattern and a wear layer, whereby said print pattern is directly applied to said substrate, and further concerns a method to produce such coverings.
1. Covering panel, configured as a floor covering, wall covering or ceiling covering, said covering panel comprising:
at least one substrate comprising at least one thermoplastic extruded polymeric PVC foam material;
at least one surface layer, said surface layer comprising a print pattern and a wear layer;
wherein said substrate further comprises chalk, or a combination of chalk and talc, and
wherein said print pattern is directly applied to said substrate.
2. Covering panel according to claim 1 , whereby said substrate and/or said wear layer comprise at least one extruded thermoplastic material comprising one or more colorants.
3. Covering panel according to claim 1 , whereby at least one colorant is distributed non-uniformly throughout said substrate and/or said wear layer to yield a variegated pattern.
4. Covering panel according to claim 1 , whereby said covering comprises any of a bevel or a locking system, whereby said print pattern is extended onto said bevel and/or said locking system.
5. Covering panel according to claim 1 , whereby said print pattern is extended onto an entire outer surface of the substrate.
6. Covering panel according to claim 1 , whereby said covering panel is provided with an embossing pattern.
7. Covering panel according to claim 1 , whereby the covering comprises a wear resistance conform the European standards EN 13329, EN 660-2 or EN 16511.
8. Method for producing covering panels, configured as a floor covering, wall covering or ceiling covering, comprising the steps of:
providing a substrate comprising at least one thermoplastic foam material;
applying to said substrate a surface layer, said surface layer comprising a print pattern and a wear layer;
wherein said substrate is provided with chalk, or a combination of chalk and talc, and
wherein said print pattern is directly applied to said substrate.
9. Method according to claim 8 , whereby said substrate and/or said wear layer is produced by extrusion of at least one thermoplastic material comprising one or more colorants.
10. Method according to claim 8 , whereby at least one colorant is distributed non-uniformly throughout said substrate and/or said wear layer to yield a variegated pattern.
11. Method according to claim 8 , whereby said print pattern is applied on said substrate using at least one colorant.
12. Method according to claim 8 , whereby said print pattern is applied on said substrate using one or more wear resistant agents.
13. Method according to claim 8 , whereby the surface of said substrate onto which the print pattern is to be applied, is pre-treated.
14. Method according to claim 8 , whereby said covering panels are provided with any of a bevel or a locking system, whereby said print pattern is extended onto said bevel and/or said locking system.
15. Method according to claim 8 , whereby said covering panels are provided with an embossing pattern prior to and/or after applying said surface layer.
16. Method according to claim 8 , whereby said print pattern is applied to said substrate by laser printing, inkjet printing, intaglio printing, screen printing or any combination of the previous.
17. Covering panel according to claim 6 , whereby said covering panel is provided with an embossing pattern in register with said print pattern.
18. Method according to claim 11 , whereby said print pattern is applied on said substrate using at least one colorant, said colorant being comprised in the form of a UV ink, a dye or a pigment, or any combinations thereof.
19. Covering panel according to claim 1 , wherein the foam material comprises cells having an average size from about 0.1 mm to about 3.0 mm, as measured by ASTM D-3576-98.
20. Covering panel according to claim 1 , wherein the foam material has a foam density equal to or more than about 400 kg/m 3 .
21. Covering panel according to claim 1 , wherein the foam material has a foam density equal to or more than about 600 kg/m 3 .
22. Covering panel according to claim 1 , wherein the foam material has a foam density equal to or more than about 1400 kg/m 3 .
23. Covering panel according to claim 1 , wherein the foam material has a foam density equal to or more than about 1600 kg/m 3 .
24. Covering panel according to claim 1 , wherein the foam material has a foam density equal of between 400 kg/m 3 and 1200 kg/m 3 .
