Abstract

A process of the manufacturing of decorative boards with an abrasion resistant surface and edges with joining functionality, the process comprising the steps; a) Cutting a carrier board to the desired dimension and molding edges with joining functionality. b) Treating at least the upper surface of the board. c) Applying radiation curable dry acrylic lacquer powder by means of electrostatic spray nozzles. d) Heating the acrylic lacquer so that it melts.
e) Curing the acrylic lacquer by means of radiation being selected from the group consisting of UV-radiation and electron beam radiation.

Claims (29)

1. A process for the manufacturing of decorative boards with an abrasion resistant surface and edges with joining functionality, the process comprising the steps;
a) cutting a carrier board to the desired dimension and molding edges with joining functionality, b) treating at least the upper surface of the board, c) applying radiation curable dry acrylic lacquer powder by means of electrostatic spray nozzles, d) heating the acrylic lacquer so that it melts, e) curing the acrylic lacquer by means of radiation, the radiation being selected from the group consisting of UV-radiation and electron beam radiation.
2. A process according to claim 1 wherein at least the upper surface of the board is sanded smooth before applying the acrylic lacquer.
3. A process according to claim 1 wherein at least the upper surface of the board is pressed with a heated calendar roller, the surface temperature of the calendar roller being in the range 45 - 150°C and that the calendar roller exerts a pressure on the board in the range 10 - 100 bar.
4. A process according to claim 1 wherein a primer is applied on the board before applying the acrylic lacquer.
5. A process according to claim 1 wherein a decorative foil is applied on the board before applying the acrylic lacquer.
6. A process according to claim 1 wherein a decor is printed on the upper surface before applying the acrylic lacquer.
7. A process according to any of the claims 4 - 6 wherein the upper surface of the board is coated with a bonding layer to an amount of 10 - 40 g / m2, that hard particles with an average particle size in the range 40 - 150 µm are sprinkled to an amount of 1 - 30 g / m2 on the sticky bonding layer, that the hard particles are selected from the group consisting of aluminum oxide, silicon oxide, silicon carbide and mixtures thereof.
