Abstract

The invention discloses an electrolytic capacitor shell cooling coating containing rare-earth elements. The electrolytic capacitor shell cooling coating comprises the following components in parts by weight: 30 parts of water-soluble resin, 10 parts of rare-earth oxide, 3 parts of red stoneware, 4 parts of polyacrylamide, 5 parts of ceramic powder, 5 parts of ethylene glycol, 5 parts of graphene, 2 parts of tourmaline, 3 parts of titanium dioxide, 5 parts of a pigment, 50 parts of deionized water, 2 parts of lead tetraoxide, 3 parts of activated carbon, 2 parts of chloroplatinic acid, 5 parts of modified corn starch, 0.5 part of sea-foam stone powder, 2 parts of silicon nitride and 2 parts of boron nitride. The rare-earth oxide coating is coated on an electrolytic capacitor shell, so that the radiation cooling effect can be effectively achieved; the experimental data show that the coating coated on the electrolytic capacitor shell can effectively guide internal temperature of the electrolytic capacitor raised due to working to the shell, and can transfer heat into an infrared radiation wave; and the work voltage of the electrolytic capacitor can also reach the stable state besides that service life of the electrolytic capacitor is prolonged.
