Abstract

The invention discloses an anti-cracking flame-retardant cable sheath material. The material is prepared from, by weight, 40-55 parts of linear low-density polyethylene, 10-15 parts of high-density polyethylene, 25-40 parts of methyl vinyl silicone rubber, 20-30 parts of ethylene-octylene copolymer, 5-10 parts of hydrogen-containing silicone oil, 4-8 parts of talcum powder, 0.5-1.5 parts of aluminum nitride nano-particles, 10-20 parts of aluminum hydroxide, 6-10 parts of zinc borate, 1-3 parts of an antioxidant, 0.1-0.3 part of chloroplatinic acid and 1-5 parts of a cross-linking agent. The anti-cracking flame-retardant cable sheath material is excellent in mechanical property, flame retardancy and cracking resistance.

Description

Technical field [0001] The invention belongs to the technical field of cables, and specifically relates to an anti-cracking flame-retardant cable sheath material and a preparation method thereof. Background technique [0002] The role of the wire sheathing material is to provide a safe insulating protective layer for the transmission metal conductor, so as to avoid the conductor leakage, short circuit and other accidents that affect the safety of power supply. Cable sheathing materials mainly include polyethylene and polyvinyl chloride. Polyvinyl chloride sheathed cables are relatively cheap, have higher heat resistance and oxygen index, are not easy to burn, simple to operate, and easy to process. As for cable sheathing materials, PVC cable sheathing materials have caused more and more environmental problems. The combustion process of PVC cables releases toxic HCl gas. In recent years, with the increase of people’s awareness of environmental protection, the The vinyl cable shea...
