Abstract

The invention belongs to the field of electric power materials, and discloses a degradable packaging plastic for electric power systems, which is prepared from the following raw materials in parts by weight: 30 parts of low-density polyethylene, 20 parts of polyvinyl alcohol, 15 parts of poly(butylene succinate), 12 parts of polyvinylpyrrolidone, 9 parts of hydroxymethyl cellulose, 7 parts of polyhydroxyacetic acid, 6 parts of chitosan, 4 parts of polylactic acid, 3 parts of triethyl phosphate, 3 parts of micalex powder, 2 parts of talcum powder, 2 parts of corn starch, 1 part of sodium succinate and 1 part of epoxy soybean oil. The plastic material has favorable tensile strength, elongation at break and biodegradability, and greatly lowers the environmental pollution.

Description

technical field [0001] The invention belongs to the field of power materials, in particular to a degradable packaging plastic used in power systems. 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, most of the outer packaging materials are plastic packaging materials. Polyethylene plastic packaging products in plastic materials are disposable packaging products with low prices 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.
