Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an electrostatic spraying coating for heat dissipation of electrical housings. Background technique [0002] In the rapid development of society, all kinds of electrical products are developing in the direction of miniaturization, light weight, compactness and high efficiency. Therefore, electronic products with high power have been developed rapidly, and the resulting large amount of heat has no space to dissipate. It will directly affect the working stability, operation safety and service life of electronic products. Conventional cooling methods can no longer meet the heat dissipation requirements of high-power electronic products, so it is necessary to improve the heat dissipation rate of electronic products. Currently, the most used is Apply heat dissipation paint. [0003] At present, manufacturers of heat-dissipating coatings mostly use carbon-based substances as heat-con...
