Novel high-hardness plastic shell composition for capacitor

Abstract

The invention discloses a novel high-hardness plastic shell composition for a capacitor. The novel high-hardness plastic shell composition is characterized by consisting of the following components in parts by weight: 35 parts of polypropylene, 15 parts of linear polyethylene, 10 parts of a high barrier film, 5 parts of polypropylene random copolymer, 5 parts of di-tert-butyl peroxide, 2 parts of cassava flour, 5 parts of modified wood plastic powder, 2 parts of tributyl citrate, 2 parts of silicone rubber, 2 parts of glycerol, 5 parts of carbon fiber, 2 parts of a rear-earth light converter, 2 parts of diphenyl silanediol, 2 parts of a plasticizer, 2 parts of silicon carbide micro powder, 2 parts of a lubricant, 2 parts of paraffin, 2 parts of vermiculite, 2 parts of sepiolite fabric, 2 parts of glass fibers, 2 parts of rear earth and 2 parts of talcum powder. The novel high-hardness plastic shell composition disclosed by the invention is simple in component and low in cost; the prepared finished product has good toughness, strong bearing capacity and high compactness, is easy to degrade and nonhazardous under a high temperature environment; meanwhile, the conventional preparation process is changed and a freezing process is increased, so that the safety of the product is improved and the product has relatively good stable performance at a relatively high temperature.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a novel plastic casing composition for high-hardness capacitors. 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, water pumps, generators, ho...
