Abstract

A thin-film capacitor housing heat dissipation coating is prepared from, by mass, 35 parts of resol, 3 parts of gelatin, 5 parts of glycidyl methacrylate, 3 parts of sodium dodecyl benzene sulfonate, 3 parts of gloss oil, 5 parts of dimethyl dicarbonate, 3 parts of olive oil, 3 parts of colored glaze carbylic acid, 3 parts of olive oil, 3 parts of graphene, 5 parts of pigment, 50 parts of distilled water, 3 parts of benzoyl paeoniflorin, 3 parts of sodium hypochlorite, 5 parts of a modifying agent, 3 parts of calcium carbonate, 3 parts of glacial acetic acid, 3 parts of magic acid, 5 parts of polyester resin, 3 parts of potassium dihydrogen phosphate, 1 part of sodium phosphate, 3 parts of aluminum silicate, 3 parts of imidazole, 3 parts of cohesive soil, 3 parts of polyvinyl alcohol and 3 parts of sodium borohydride. The modifying agent is added in a traditional formula to perform modification processing, the coating coated on a capacitor housing can effectively guide capacitor inside temperature rising due to work to the housing and convert heat into infrared radiation waves, and the working voltage of a capacitor can be also in a stable state in addition to prolonging of the service life of the capacitor.

Description

technical field [0001] The invention relates to the technical field of heat-dissipating coatings, in particular to a heat-dissipating coating for a film capacitor casing and a preparation method thereof. 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.

Problems solved by technology

[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, capacitor shells are generally covered with PET as the appearance condition. The general service life of PET materials is about 1 year. After 1 year, they are easy to break and smash, and capacitor products will generate heat during use. Diffusion, the capacitor will age ahead of time as the temperature increases, and the temperature change under long-term work will also cause the power supply of electronic components to be unstable, causing certain harm
