AI Technical Summary

Problems solved by technology

Because there is basically no recycling value, the recovery rate is extremely low. Because of its light weight and difficult to degrade, it drifts with the wind, pollutes the land and water, and accounts for the main part of the white garbage that has formed in our country.

Abstract

The invention discloses a degradable cable insulating material, and belongs to the technical field of electric power materials. The degradable cable insulating material mainly comprises, by mass, 95-100 parts of polylactic acid, 22-25 parts of polyhexanediol, 10-12 parts of polyhydroxybutyrate, 10-12 parts of a photosensitizer, 25-28 parts of a straw filler, 21-23 parts of decabromodiphenylethane, 17-19 parts of hydroxyethyl cellulose, 50-55 parts of thermoplastic starch, 23 parts of an inorganic filler, 18-19 parts of polydiethylene glycol hexandioic ester and 1-1.2 parts of an antioxidant. The degradable cable insulating material has the advantages of low price and reasonable compatibility of raw materials, good flame retardation and full biodegradability, and is mainly used for making cables.

Description

technical field [0001] The invention belongs to the technical field of electric power materials, and in particular relates to a degradable cable insulating material. Background technique [0002] The outer packaging of cables and electrical appliances is mostly made of lightweight plastic materials to avoid damage or corrosion. After the outer packaging plastic materials are removed, most of them are disposed of as waste anywhere, which is likely to cause environmental pollution. At present, polyethylene plastic packaging products in plastic materials are disposable packaging products with low price and are widely used in daily life. Because there is basically no recycling value, the recovery rate is extremely low. Because of its light weight and non-degradable characteristics, it drifts with the wind, pollutes the land and water, and accounts for the main part of the white garbage that has formed in our country. Contents of the invention [0003] The purpose of the pres...
