Abstract

The invention discloses a high-flame-retardancy electrostatic spraying paint which is prepared from an unsaturated polyester resin, an acrylic resin, a methylphenyl silicone resin, a curing agent, fumed silica, polyamide wax, modified glass microspheres, kaolin, erbium oxide, titanium white, octadecendioic acid, a flame retardant, a leveling agent, a degasifier and a dispersing agent. The flame retardant is prepared from magnesium oxide hydrate, hydrated alumina, a melamine formaldehyde resin, ammonium phosphomolybdate, di(ethanediol) phenylphosphate and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide. The high-flame-retardancy electrostatic spraying paint has the advantages of high adhesive force with the substrate, excellent flame retardancy and favorable heat resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high flame-retardant electrostatic spray coating. Background technique [0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the direction opposite to the electric field, and adsorb the paint particles on the surface of the workpiece. Due to its high utilization rate, it can realize mechanization, automation, and assembly line The advantages of production, strong adhesion, smooth coating surface, small roughness, and little pollution to the environment have gradually replaced the traditional painting process in recent years. At present, the electrostatic spray coatings used in the market are mainly oil-based alkyd amino paints and acrylic paints. As organic polymer materials, they have the defects of poor flame retardancy and easy combustion of the coating during use. appli...
