High-temperature-resistant capacitor plastic shell and preparation method thereof

Abstract

A high-temperature-resistant capacitor plastic shell consists of the following components in parts by weight: 35 parts of polypropylene, 15 parts of linear polyethylene, 10 parts of methyl silicone rubber, 5 parts of diphenyl silanediol, 5 parts of dimethyl siloxane, 5 parts of nano silica, 5 parts of a modified wood plastic powder, 2 parts of azadirachtin, 2 parts of an emulsifier, 2 parts of soybean oil, 5 parts of carbon fibers, 5 parts of metallocene polyethylene, 0.5 part of a catalyst, 2 parts of a plasticizer, 2 parts of oxidized polyethylene, 2 parts of cyclohexanone, 2 parts of paraffin, 2 parts of boron fibers, 2 parts of sepiolite velvet, 2 parts of glass fibers, 2 parts of butyl acetate, and 2 parts of a talc powder. The high-temperature-resistant capacitor plastic shell has the advantages of simple components, and low cost; the prepared finished product has the advantages of high temperature resistance, stable performance, and no toxicity under a high-temperature environment; and at the same time, due to change of a conventional preparation process, a freezing process is increased, the safety of the product is improved, and the product still has relatively good stable performance at higher temperatures.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a molded case of a high-temperature resistant capacitor and a preparation method thereof. Background technique [0002] CBB60 capacitors are mainly used in refrigerators, air conditioners, AC motors, water pumps, generators, household appliances, electronic products, etc. The product has good stability, impact current resistance, strong overload capacity, low loss, high insulation resistance, long rated working life, excellent self-healing performance, built-in flame-retardant epoxy resin filling is safe and reliable, and the capacitor is non-toxic and leak-free. materials, which are conducive to environmental protection and other characteristics. Because the core of the product can be wound with a mandrel, it can also be wound with a mandrel without a mandrel, so the production method is flexible. This product is mainly used in refrigerators, air conditioners, AC motors, wa...
