UV (ultraviolet) curing coating with functions of light energy absorption and heat conduction and preparation method of coating

Abstract

The invention discloses an UV curing coating with functions of light energy absorption and heat conduction. The coating is prepared by raw materials in parts by weight as follows: 10-12 parts of unsaturated polyester resin 196, 50-55 parts of epoxy acrylate, 1-2 parts of nano tungsten trioxide, 1-2 parts of nano silicon carbide, 3-4 parts of alpha-hydroxylalkyl phenyl ketone, 1-2 parts of carboxymethylcellulose, 1-2 parts of methyl methacrylate, 3-4 parts of methacrylic acid, 10-20 parts of diethylene glycol monoethyl ether acetate, 1-2 parts of polytetrafluoroethylene, 3-4 parts of 2-butoxyethanol, 1-2 parts of isopropyl alcohol, 10-12 parts of ethoxylated trimethylolpropane triacrylate and 4-5 parts of a dispersing auxiliary. According to the coating, the nano tungsten trioxide is adopted, so that the coating has excellent solar energy absorption capacity; the nano silicon carbide is adopted, so that the coating has excellent heat-conducting property; the nano tungsten trioxide and the nano silicon carbide are combined, so that heat can be rapidly absorbed and conducted; the unsaturated polyester resin 196 and other various monomers are used for polymerization, so that the coating has the characteristics of high impact strength and good toughness; and the coating is suitable for coating of the surface of equipment and heat dissipation parts of an optical instrument.

Description
