<p>The present invention relates to a method for coating thermoplastic resin powder on the surface of a wood board or a paper board, which comprises the following steps: (a) preheating a wood board or a paper board or a wood board or a paper board not coated with a liquid primer at 100-300°C which is a melting temperature of a thermoplastic resin to be surface-coated; (b) powder-coating thermoplastic resin powder on the preheated surface of the wood board or the paper board in the thickness of 200-1,500 um; and (c) performing post-thermal treatment on the powder-coated wood board or paper board, thereby coating functional plastic resin powder having water resistance, corrosion resistance, abrasion resistance, or electrical conductivity on the surface of a wood board or a paper board which is a non-conductive material having absorbability, and impossible of electrostatic powder coating by a powder coating method.</p> |
