Heat-dissipating spraying powder for household electrical appliances

Abstract

The invention especially relates to a heat-dissipating spraying powder for household electrical appliances, belonging to the field of powdery paints. The heat-dissipating spraying powder comprises, byweight, 50 to 70% of resin, 3 to 7% of a curing agent, 2 to 4% of auxiliary agents, 15 to 25% of a pigment and 10 to 15% of a filler, wherein the auxiliary agents are composed of, by weight, 40 to 60% of graphene, 10 to 15% of a charge increasing agent, 10 to 15% of a flowing agent and 15 to 20% of a loosening agent. To guarantee the spraying effect and heat-dissipating effect of the powder, thecharge increasing agent, the flowing agent, the loosening agent and graphene are used as the auxiliary agents, and graphene facilitates heat dissipation in virtue of its excellent performance and improves the shock strength of the powder.

Description

technical field [0001] The invention relates to powder coatings, in particular to a heat-dissipating spray powder for household appliances. Background technique [0002] In the rapid development of society, the penetration rate and utilization rate of household appliances are getting higher and higher, and all kinds of electrical products are developing in the direction of miniaturization, light weight, compactness and high efficiency, so electronic products with high power are gaining rapid development, and the resulting large amount of heat has no space to dissipate, which will directly affect the working stability, operational 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 To improve the heat dissipation rate of electronic products, the most used at present is to apply heat dissipation coatings. [0003] At present, the heat-dissipat...

[0002] In the rapid development of society, the penetration rate and utilization rate of household appliances are getting higher and higher, and all kinds of electrical products are developing in the direction of miniaturization, light weight, compactness and high efficiency, so electronic products with high power are gaining rapid development, and the resulting large amount of heat has no space to dissipate, which will directly affect the working stability, operational 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, and the most widely used at present is to apply heat dissipation paint

[0003] At present, the heat-dissipating fillers commonly used in heat-dissipating coatings are aluminum nitride, silicon nitride, aluminum oxide, beryllium oxide, magnesium oxide, silicon oxide, and zinc oxide. The high toxicity of organic solvents will cause environmental pollution, and partial gelation will occur. Therefore, there is a need for a low-cost, environmentally friendly heat-dissipating coating that does not appear to be gelled.
