Abstract

The method relates to a floor panel (100), more particularly a laminate floor, with resin-impregnated, more particularly paper layers (10, 11, 13), which are pressed together with a carrier board (12). In order to design a floor (100) in such a way that a conductive and transparent layer can be positioned at any point in the sequences of layers of the floor panel (100) in order to achieve an antistatic effect the invention proposes providing at least one layer (10, 11, 13) is provided with conductive and transparent pigments (16).

Claims

1-17. -17. (canceled)

18. Floor panel comprising resin-impregnated layers which are pressed together with a carrier board wherein at least one layer has transparent and conductive pigments.

19. The floor panel according to claim 18, wherein the floor panel is laminate flooring,

20. The floor panel according to claim 18, wherein the resin-impregnated layers are paper layers.

21. The floor panel according to claim 18 comprising a first layer of impregnated overlay paper, which is arranged on a printed, impregnated paper decorative layer, whereby the printed, impregnated paper decorative layer is positioned above the carrier board and underneath the carrier board is positioned an impregnated backer paper as layer.

22. The floor panel according to claim 18, characterised in that above the carrier board is arranged a printed impregnated paper decorative layer and below the carrier board is arranged an impregnated backer paper layer, whereby on the printed paper is positioned a resin layer on the side facing away from the carrier board.

23. The floor panel according to claim 18, characterised in that the resin-impregnated layer further comprises corundum particles.

24. The floor panel according to claim 18, characterised in that the carrier board is a composite wood board.

25. The floor panel according to claim 24, characterised in that the composite wood board is a wood fibre board or a particle board.

26. The floor panel according to claim 18, wherein the resin-impregnated layers are impregnated with melamine and/or urethane resins.

27. The floor panel according to claim 18, wherein the transparent and conductive pigments are glimmer pigments.

28. The floor panel according to claim 18, wherein the resin-impregnated layers contain pigment in a concentration corresponding to an application weight of the glimmer pigment of 0.1-15 g/m².

29. The floor panel according to claim 18 which further comprises a layer on which is a printed image, whereby the pigments are between a resin-impregnated layer and the printed image and/or between a resin-impregnated layer and the carrier board, and/or between the carrier board and the resin-impregnated layer.

30. The floor panel according to claim 19, wherein the resin-impregnated layers are pressure or thermally pressed with the carrier board.

31. The floor panel according to claim 18, wherein at least one resin-impregnated layer is provided with a resin layer that contains pigments.

32. A method of manufacturing a floor panel, comprising the steps of arranging at least one layer of transparent and conductive pigment on a resin-impregnated layer, followed by pressing resin-impregnated layers with a carrier board.

33. The method according to claim 32, wherein the floor panel is laminate flooring,

34. The method according to claim 32, wherein the resin-impregnated layers are paper layers.

38. The method according to claim 32 wherein the pressing is carried out under pressure and/or heat.

39. The method according to claim 32 wherein the pigments are added in the form of glimmer pigments.

40. A floor panel produced by the method of claim 32.
