Problems solved by technology

Most rubber molecular chains contain unsaturated bonds. Under the action of heat, oxygen, ozone and other effects, the rubber macromolecular chains are easily broken and over-crosslinked, which causes the rubber molecules to age and gradually lose their valuable properties; therefore, the rubber's Aging resistance and protection are the hotspots of current research

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-strength and aging-resistant natural rubber / nitrile rubber cable material. Background technique [0002] Rubber includes natural rubber and synthetic rubber. Natural rubber is mainly composed of polyisoprene. Commonly used synthetic rubber includes butadiene rubber, styrene-butadiene rubber, nitrile rubber, ethyl styrene rubber, etc. Natural rubber and synthetic rubber have different molecular structures and uses, and have been widely used in various fields such as tires, rubber hoses, tapes, rubber shoes, sealing products, and cables. Most rubber molecular chains contain unsaturated bonds. Under the action of heat, oxygen, ozone and other effects, the rubber macromolecular chains are easily broken and over-crosslinked, which causes the rubber molecules to age and gradually lose their valuable properties; therefore, the rubber's Aging resistance and protection are...
