Problems solved by technology

[0003] The heat dissipation coatings currently produced are generally used in the heat dissipation of components of electronic products such as CPUs and LED lamps. The requirements for the medium for painting are relatively high, and the adhesion to rough and loose surfaces is not strong, so the use effect is not ideal. Small scope of application

Abstract

The invention discloses electroplating-imitation heat dissipation coating. The electroplating-imitation heat dissipation coating is prepared from the following raw materials in parts by weight: 92-100 parts of high-density polyethylene, 2-3 parts of polyvinylidene fluoride, 1-2 parts of butyltin oxide, 8-10 parts of acrylonitrile-butadiene-styrene copolymer, 1-2 parts of N,N-diethyl aniline, 6-8 parts of dibutyl phthalate, 0.6-1 part of 1-hydroxyl cyclohexyl phenyl ketone, 6-10 parts of fluorite powder, 1-2 parts of polyvinyl pyridine, 2-3 parts of polyvinyl alcohol, 1-2 parts of nanometer aluminum powder and 6-10 parts of composite filler. The powder coating disclosed by the invention can be used for surface coating of lamp tube housing, has a very good heat dissipation effect, certain metal texture, good leveling property and excellent combination performance and is pollution-free to environments.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to an imitation electroplating heat dissipation coating. Background technique [0002] Thermally conductive and heat-dissipating coatings are widely used in fields that require heat dissipation, such as computers, notebook computers, LED lighting, communications, rectifiers, medical and industrial equipment, and are mainly coated on the surface of radiators. [0003] The heat dissipation coatings currently produced are generally used in the heat dissipation of components of electronic products such as CPUs and LED lamps. The requirements for the medium for painting are relatively high, and the adhesion to rough and loose surfaces is not strong, so the use effect is not ideal. The scope of application is small. Contents of the invention [0004] The purpose of the present invention is to provide a kind of imitation electroplating heat dissipation paint. [0005] The present inventio...
