Problems solved by technology

[0004] At present, the shell of electrolytic capacitors is generally covered with PET as the appearance condition. The general service life of PET materials is about 1 year. Effective solution or diffusion, electrolytic capacitors will age ahead of time as the temperature increases. Under long-term work, due to temperature changes, the power supply of electronic components will also be unstable, causing certain harm

Abstract

A coating that uses graphene microflakes as the main agent to coat the shell of an electrolytic capacitor to produce heat dissipation, relates to the technical field of heat dissipation coatings, and is composed of the following components in mass percentages: 45% to 55% of a permanent resin, 10 to 15% of a cosolvent, 15-20% water, 15-25% filler, 5-10% pigment; the filler is a mixed powder of graphene microflakes and carbides and nitrides, using the conduction function of nitrides and oxides themselves, crystal and flake Combined to generate heat energy connection, graphene sheet material can enhance the area and intensity of infrared radiation heat dissipation, and achieve effective radiation heat dissipation conditions. The invention adopts special structure graphene microchips and carbides and nitrides to cooperate, and the prepared coating has the characteristics of good heat dissipation effect and low price, will not pollute the environment, and will not cause gelation; the dispersibility is better than that of melting and mixing The method should be superior; the spraying effect and the leveling effect of the coating film are good.

Description

technical field [0001] The invention relates to the technical field of heat-dissipating coatings, in particular to a coating that uses graphene microchips as the main agent to coat the shell of an electrolytic capacitor to produce heat dissipation 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. 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. [00...
