Silane crosslinked rubber cable sheath material

Abstract

The invention provides a silane crosslinked rubber cable sheath material and belongs to the technical field of chemical engineering. The silane crosslinked rubber cable sheath material is prepared from, by weight, 30-40 parts of ethylene propylene rubber, 10-15 parts of nitrile rubber, 15-20 parts of polyvinyl chloride, 15-20 parts of polyethylene, 3-4 parts of an anti-aging agent, 3-4 parts of a vulcanizing agent, 3-4 parts of vinyl silane, 1-2 parts of an initiator, 1-2 parts of a crosslinking catalyst, 2-3 parts of carbon black, 2-3 parts of a flame retardant, 2-3 parts of a softener, 2-3 parts of an antistatic agent and 2-3 parts of an aluminate coupling agent. The added nitrile rubber has excellent oil resistance and solvent resistance. The added polyvinyl chloride has excellent flame retardance, insulativity and mechanical properties. The environmentally friendly polyethylene and the anti-aging agent are adopted, so that the environmental performance of products is improved. The added cross-linking agent and vulcanizing agent can improve the mechanical properties of the rubber material, and the rubber becomes softer and more elastic and does not stick to rollers. The cable sheath material prepared through reasonable raw material preparation has excellent mechanical properties, environmental protection property, softness, aging resistance, weather resistance, chemical resistance and flame retardance.

Description

technical field

[0001] The invention belongs to the technical field of chemical industry, and in particular relates to a silane crosslinked rubber cable sheath material Background technique

[0002] The wire and cable industry is an important supporting industry for my country's economic construction. It is widely used in various fields of the national economy. Wire and cable are indispensable basic equipment for transmitting electric energy, transmitting information and manufacturing various motors, electrical appliances, instruments, automobiles, machine tools, etc. Wire and cable provide infrastructure for the power industry and communication industry, accounting for 1 / 4 of the output value of my country's electrical industry. It is the second largest industry in China after the automobile industry. The product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the ...
