Abstract

The invention discloses a heatproof oil-resistant cable. The heatproof oil-resistant cable comprises a cable core. The cable core comprises a conductor and an insulating layer. The cable core is externally provided with an inner sheath layer. A steel band armor layer is arranged outside the inner sheath layer. An outer sheath layer is arranged outside the steel band armor layer. The outer sheath layer is made of a heatproof oil-resistant modified terpolymer EP rubber material. The raw materials of the heatproof oil-resistant modified terpolymer EP rubber material comprises terpolymer EP rubber, nitrile rubber, carbon nanotube, nano-alumina, modified attapulgite, eleaostearic acid, zinc oxide, sulphur, 4, 4'-dithiomorpholine, 1,1,3-3(2-methyl-4-hydroxy-5-tert-butyl phenyl) butane, N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine, a promoter M, a promoter DM, dicyclohexyl phthalate, dioctyl phthalate and a silane coupling agent. The heatproof oil-resistant cable is good in oil resistance and heat resistance, the aging resistance is good, and the service lifetime is long.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a heat-resistant and oil-resistant cable. Background technique [0002] Compared with other diene rubbers, EPDM not only has excellent heat resistance, oxygen resistance, ozone resistance, weather resistance and aging resistance, but also has good chemical resistance, electrical insulation performance and low temperature performance. In addition, three Ethylene propylene rubber also has low density, high filling, hot water resistance and water vapor resistance, and has good compatibility with various high polymers. Now it has been widely used in building waterproof materials, auto parts, wire and cable protection. In other products such as sleeves, heat-resistant hoses, tapes, and automotive seals. However, EPDM rubber also has shortcomings such as oil resistance and poor adhesion. [0003] With the rapid development of society, especially the development of the power industry, ...
