Abstract

The invention discloses an EPDM (ethylene propylene diene monomer) rubber insulated / jacketed cable with high strength, oil resistance and aging resistance. The EPDM rubber insulated / jacketed cable comprises following raw materials: EPDM rubber, nitrile butadiene rubber, maleic anhydride grafted polypropylene, an ethylene-vinyl acetate copolymer, diphenyl hexadiphthalein diamine, stearic acid, zinc oxide, superfine fully vulcanized powder nitrile butadiene rubber, tin(II) chloride dehydrate, bromo-octyl-phenolic curing resin, calcined kaolin, zinc methacrylate, carbon nano tubes, superfine silica, calcium sulfate whiskers, polyacrylonitrile fibers, a silane coupling agent, lanthanum glutamic dithiocarbamate, petroleum wax, naphthenic oil, an anti-aging agent and an accelerator. The EPDM rubber insulated / jacketed cable material with high strength, oil resistance and aging resistance serves as insulation and / or a jacket in a cable and has high strength, good oil resistance, aging resistance and combination properties and long service life.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength, oil-resistant and aging-resistant EPDM insulation / sheath cable. Background technique [0002] EPDM rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil filling and excellent processing performance. It is a commonly used cable material. With the development, people have put forward higher requirements on the performance of cables, and the cable materials used in cables are also required to have excellent comprehensive properties, such as being able to withstand exposure to the sun, wind and rain, high temperature and other environments for a long time, and have excellent oil resistance and aging resistance. However, the existing EPDM cable materials have disadvantages such as poor oil resistance, low strength, limited service temperature range, and...
