Problems solved by technology

[0002] Traditional capacitor casings are made of aluminum or plastic products, which are easily damaged in harsh environments such as corrosive acid and alkali, high temperature, low temperature, high pressure or ozone, which affect the normal operation of the capacitor, not only causing a waste of resources, but also in terms of safety. There is no effective guarantee, and the technology of using a metal mesh inner skeleton on the shell of the capacitor and wrapping the rubber material on the outside has not appeared so far.

Abstract

The invention discloses a heat-resistant rubber capacitor case packaging material. The heat-resistant rubber capacitor case packaging material consists of the raw materials including chloroprene rubber CR121, a SG-4 polyvinyl chloride (PVC) resin, poly-4-methyl-1-amylene, N, N'-m-phenylenedimaleimide, alumina powder, barium sulfate powder, an anti-aging agent RD, 2-mercaptobenzimidazole, zinc stearate, an accelerator CZ1-2, an accelerator DM, 3-aminopropyl trimethoxy silane, an aluminate coupling agent DL-411, an oxidant, highly-wear-resistant carbon black N330, carbon black N220, imarcaptoacetate dioctyltin, epoxy ethylhexyl stearate, glycerin triacetate, sodium bicarbonate, modified coal ash and dicyclopentadienyl iron. By virtue of a reasonable formula of the raw materials, the produced rubber material has good comprehensive performance and is high in metal adhesion, mechanical property, fatigue resistance, ageing resistance and the like, and can provide high-strength protection for capacitors.

Description

technical field [0001] The invention mainly relates to a rubber wrapping material, in particular to a heat-resistant capacitor shell rubber wrapping material. Background technique [0002] Traditional capacitor casings are made of aluminum or plastic products, which are easily damaged in harsh environments such as corrosive acid and alkali, high temperature, low temperature, high pressure or ozone, which affect the normal operation of the capacitor, not only causing a waste of resources, but also in terms of safety. There is no effective guarantee, and the technology of using a metal mesh inner skeleton on the outer shell of the capacitor and wrapping the rubber material on the outside has not appeared so far. Contents of the invention [0003] The object of the present invention is to provide a heat-resistant capacitor casing rubber wrapping material. [0004] The present invention is achieved through the following technical solutions: [0005] A heat-resistant capa...
