Heat-dissipation paint for iron casting surfaces

Abstract

The invention provides a heat-dissipation paint for iron casting surfaces, relating to the technical field of heat-dissipation paints. The invention is characterized in that the heat-dissipation paint is composed of the following components in parts by weight: 30 parts of water-soluble epoxy resin, 5 parts of kyanite powder, 3 parts of silica sol, 4 parts of zircon flour, 3 parts of aluminum oxide, 5 parts of calcined potash feldspar, 2 parts of xylitol, 2 parts of calcined kaolin, 3 parts of barite powder, 5 parts of large-granule graphite, 50 parts of deionized water 2 parts of hexatitanium crystal whisker, 2 parts of flake graphite, 2 parts of zirconia, 5 parts of modifier, 2 parts of nano anion powder, 2 parts of silicon nitride, 2 parts of chromite powder, 2 parts of boric acid water solution, 1 part of nano titanium dioxide, 2 parts of polyester polyol and 2 parts of slaked lime powder. By adding the modifier into the traditional formula to perform modification treatment, the coated heat-dissipation paint can effectively achieve the effects of radiation and heat dissipation, has the advantages of low cost, low harm to the human body, high coating strength, no crack, no blister, uniform coating and high surface quality.

Description

technical field [0001] The invention relates to the technical field of heat dissipation coatings, in particular to heat dissipation coatings for the surface of iron castings. 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] The heat dissipation coating is to enhance the heat dissipation performance of the object by improving ...

AI Technical Summary

Problems solved by technology

[0004] 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.
