Oxidation-resistant capacitor film

Abstract

The invention relates to an oxidation-resistant capacitor film, made from, by weight, 10-15 parts of epoxy resin, 2-8 parts of polyethylene resin, 12-14 parts of hydrogenated butadiene-acrylonitrile rubber, 3-5 parts of polyethyl ester, 4-6 parts of polypropylene, 4-8 parts of tri(propylene glycol) butyl ether, 10-15 parts of polystyrene, 11-13 parts of allyl alcohol, 20-25 parts of polyoxyethylene ether, 2-5 parts of methyl hydrogen silicone oil, and 1-5 parts of ethylene-vinyl acetate copolymer. The oxidation-resistant capacitor film provided herein has excellent oxidation resistance, is not easy to be oxidized by air or water, and provides greatly prolonged life for a capacitor.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to an oxidation-resistant capacitor film. Background technique [0002] There are many types of capacitors depending on the medium, such as: electrolytic capacitors, paper capacitors, film capacitors, ceramic capacitors, mica capacitors, air capacitors, etc. However, the most frequently used in audio equipment are electrolytic capacitors and film (Film) capacitors. Electrolytic capacitors are mostly used in places that require a large capacitance, such as the filter capacitor of the main power supply, which is used for storing electric energy in addition to filtering. Film capacitors are widely used in the cross-connection of analog signals and the bypass (reverse cross-connection) of power supply noise. [0003] In the prior art, during the use of the film capacitor, due to the heat energy generated by conduction, the internal material of the film capacitor is easily oxidized,...
