Abstract

The invention discloses an anti-aging and flame-retardant power cable sheath material. The anti-aging and flame-retardant power cable sheath material comprises, by mass, 30-40 parts of low density polyethylene, 15-20 parts of PVC resin, 2-4 parts of vinyl trimethoxy silane, 1-2 parts of trioctyltrimellitate, 0.8-1.2 parts of vulcanizing agent, 3-5 parts of flame retardant, 2-4 parts of aluminum hydroxide, 1.2-1.6 parts of nitrile-butadiene rubber, 2-4 parts of active calcium carbonate, 0.6-0.8 part of stabilizer, 60-80 parts of butadiene styrene rubber, 20-40 parts of epoxidized natural rubber, 5-10 parts of ethylene / vinyl acetate copolymer, 10-30 parts of nano white carbon black and the like. The cable sheath material has excellent anti-aging performance and flame-retardant performance and is high in strength and environmentally friendly, and a manufactured cable sheath is good in comprehensive performance and long in service life.

Description

technical field [0001] The invention belongs to the technical field of power cable production, and in particular relates to an aging-resistant and flame-retardant power cable sheath material. Background technique [0002] With the rapid development of power cable buried laying projects, higher requirements are put forward for cable protection. The cable protection sleeve is made of polyethylene PE and high-quality steel pipes, which are pre-treated by sandblasting and shot blasting, impregnated with plastic or coated, and heated and cured. Craft made. It is the most commonly used electrical insulating tube for protecting wires and cables. It is widely used because of its good insulation performance, high chemical stability, no rust, no aging, and adaptability to harsh environments. [0003] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. ...
