Environment-friendly heat-proof composite elastic cable material for cables and cords

Abstract

The invention provides an environment-friendly heat-proof composite elastic cable material for cables and cords. The environment-friendly heat-proof composite elastic cable material is prepared from the following raw materials in parts by weight: 30 to 40 parts of polyvinyl chloride resin, 20 to 30 parts of silicone rubber, 20 to 30 parts of polyacrylate rubber, 5 to 8 parts of soybean oil, 10 to 15 parts of bis(2-ethylhexyl) terephthalate, 6 to 8 parts of trioctyl trimellitate, 8 to 10 parts of tributyl citrate, 1 to 2 parts of a crosslinking agent TAC, 12 to 15 parts of ground calcium carbonate, 12 to 14 parts of mica powder, 10 to 12 parts of clay powder, 8 to 10 parts of carbon black powder, 6 to 8 parts of bentonite, 8 to 10 parts of aluminium hydroxide, 2 to 4 parts of talc powder, 1 to 2 parts of nano boron carbide, 1 to 3 parts of phosphoguanidine, 6 to 8 parts of zinc borate, 1 to 2 parts of stearic acid, 2 to 4 parts of high-melting-point paraffin, 1 to 2 parts of semi-refined paraffin wax, 5 to 8 parts of hydrotalcite, 3 to 4 parts of phosphite ester and 5 to 8 parts of modified filler. A cable processed with the cable material provided by the invention can resist high temperature, and the temperature resisting grade is 125 DEG C; the cable material has the advantages of environment-friendliness, good mechanical material performance and the like.

AI Technical Summary

Benefits of technology

This new type of insulating rubber compound can be used on both electricity transmission lines (wiring) or power supply distribution systems without causing damage during use due its properties such as low smoke emissions, excellent chemical stability over time, long lifespan, no harmful gases released when burning, strong impact strength at room temperatures compared to other types of electrical tape, etc., which makes it ideal for applications where fire safety regulations are strictly enforced.

Problems solved by technology

This patented technical problem addressed in this patents relates to reducing the risk of fire from exposure during use of highly durably colored plenum insulated electric conductors used under severe conditions such as those found on aircraft wings. Current methods involve adding an anti-fuse agent that can be harmful when exposed to certain substances like alcohol (ethanol). Therefore there has been research into developing new types of compositions with better resistance against burning while maintaining good flexibility without compromising their strength characteristics.
