Abstract

The invention relates to the field of treatment technologies for the surfaces of wooden furniture, particular relates to a coating treatment technology for the surfaces of wooden furniture, and provides coating powder for the surfaces of wooden furniture. The coating powder comprises, by weight, 50-70 parts of unsaturated polyester resin, 5-8 parts of isocyanuric acid tri-glycidyl ester, 1-3 parts of acrylate leveling agents, 3-5 parts of organosilicon leveling agents, 3-5 parts of silicon dioxide matting agents, 0.5-1.5 parts of PTFE (polytetrafluoroethylene)-modified polyethylene wax micro-powder, 0.1-0.3 part of catalysts, 2-4 parts of pigment, 5-10 parts of titanium dioxide powder and 10-30 parts of composite fillers. The coating powder has the advantages that the coating powder is environmentally friendly, is non-toxic, is free of waste and can be recycled; the coating powder which is environmentally friendly and is free of paint emission or formaldehyde is coated on the surfaces of the wooden furniture instead of the traditional contaminative paint which is extensively used for being coated on the surfaces of existing wooden furniture at present, accordingly, obvious environmental protection effects can be realized, and working environments can be improved for coating workers.
