Problems solved by technology

[0002] At present, the coatings sprayed on the aluminum shell of capacitors generally have a low service life. After long-term use, the coating film is easy to crack and shatter, and the capacitor product will generate heat energy during use. If the heat energy cannot be effectively resolved or diffused, the capacitor will advance with temperature. Aging life, long-term work due to temperature changes, will also cause instability in the power supply of electronic components, causing certain harm

Abstract

The invention discloses a capacitor aluminum shell high-temperature-resistant paint which is prepared from a polyamide resin, polyvinyl alcohol, polymethyl methacrylate, diatomite, a phenolic resin, silicone oil, aluminum silicate, olive oil, sodium phosphate, wheat hull ash and a corn straw extract. After being sprayed on the capacitor aluminum shell surface, the capacitor aluminum shell paint has favorable curing effect, can effectively protect the capacitor, has favorable heat resistance and wear resistance, and can effectively achieve the heat radiation effect under the synergistic actions of the corn straw extract and wheat hull ash.

Description

technical field [0001] The invention relates to the technical field of coatings for aluminum shells of capacitors, in particular to a high-temperature-resistant coating for aluminum shells of capacitors. Background technique [0002] At present, the coatings sprayed on the aluminum shell of capacitors generally have a low service life. After long-term use, the coating film is easy to crack and shatter, and the capacitor product will generate heat energy during use. If the heat energy cannot be effectively resolved or diffused, the capacitor will advance with temperature. Aging life, long-term work due to temperature changes will also cause instability in the power supply of electronic components, causing certain hazards. Contents of the invention [0003] The purpose of the present invention is to provide a high temperature resistant coating for capacitor aluminum case. [0004] The present invention is realized through the following technical solutions: [0005] A high-...
