Abstract

The invention discloses high-performance capacitor aluminum case film coating paint and a preparation method thereof. The high-performance capacitor aluminum case film coating paint is mainly obtained through mixing and stirring compounds A and compounds B in raw materials according to certain weight parts, wherein the compounds A consist of polyamide resin, epoxy resin, ketone, nanometer carbon powder, ethanol, propanetriol and attapulgite, and the compounds B consist of acrylic ester copolymer modifying agents, silane coupling agents, graphite powder, silane and straw ashes. The capacitor aluminum case film coating paint has the advantages that the recipe is reasonable, the preparation method is simple, the curing effect on a capacitor aluminum case is good, a capacitor is effectively protected, the prepared film coating paint has the heat resistance performance and the wear resistance performance, and the service life of the capacitor is prolonged.

Description

technical field [0001] The invention relates to a capacitor casing and a chemical composition, in particular to a high-performance 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 service life i...
