Abstract

The invention discloses an environmentally-friendly laminating coating for an aluminum capacitor shell and a preparation method thereof. The environmentally-friendly laminating coating is mainly obtained by mixing and stirring a composition A and a composition B in composition raw materials in part by weight, wherein the composition A consists of polyethylene resin, ketone, polyethylene wax, isopropanol and attapulgite; and the composition B consists of phenolic resin, polydimethylsiloxane, a silane coupling agent, stearic acid, graphite powder and tetramethylsilane. The environmentally-friendly laminating coating has a reasonable formula, a simple preparation method and a good curing effect on the aluminum capacitor shell; a capacitor is protected effectively; and the obtained laminating coating has heat resistance and wear resistance performance, and contributes to prolonging the service life of the capacitor.

Description

technical field [0001] The invention relates to a capacitor casing and a chemical composition, in particular to a green and environment-friendly capacitor aluminum casing coating and a preparation method thereof. Background technique [0002] With the advancement of technology in the electronics industry, the manufacturing technology of electronic circuit boards has also made great progress. In order to reduce the size of electronic products and reduce consumption, electrolytic capacitors, as one of the general components on electronic circuit boards, are not only important for their temperature resistance, The requirements for breakdown resistance are getting higher and higher, and the smaller the occupied area, the better. The occupied area of ​​electrolytic capacitors should be small. First, the aluminum case of the capacitor should have a high aspect ratio, and the occupied area should be small if the diameter of the capacitor is small; It is easy to be damaged and the ...
