High-strength corrosion-resistant cable for coal mine

Abstract

The invention provides a high-strength corrosion-resistant cable for a coal mine. The cable comprises a cable core, an insulating layer and a sheath layer, wherein the sheath layer comprises the raw materials in parts by weight: 65 parts of highly chlorinated polyethylene, 50 parts of ethylene propylene rubber, 35 parts of nitrile rubber, 35 parts of EVA resin, 2.0 parts of a vulcanizing agent BCPO, 1.5 parts of a vulcanizing agent triallyl isocyanurate, 0.5 part of a vulcanizing accelerant TMTD, 1.0 part of an assistant crosslinking agent TAIC, 4 parts of oxidized polyethlene wax, 18 parts of nano kaolin, 10 parts of mountain flour, 5 parts of precipitated white carbon black, 6 parts of argil, 12 parts of semi-reinforced carbon black, 25 parts of magnesium hydrate, 4.0 parts of magnesium oxide, 3.5 parts of zinc oxide, 1.5 parts of stearic acid, 4.0 parts of a calcium and zinc stabilizer, 3.5 parts of paraffin and 2.0 parts of an anti-aging agent RD. The invention further provides a preparation method for the high-strength corrosion-resistant cable for the coal mine. The cable provided by the invention has temperature-resisting and corrosion-resisting properties, and is extremely excellent in tear resistance.

Description

technical field [0001] The invention relates to the technical field of cable rubber, in particular to a high-strength corrosion-resistant cable for coal mines. Background technique [0002] In recent years, with the rapid development of China's economy, the contradiction of tight energy supply has become more and more prominent. In order to meet this demand, major coal mines have adopted high-power coal mining equipment to increase production capacity, and the supporting cables for power transmission Ethylene-propylene rubber insulation has high operational reliability and other advantages, such as high moisture resistance, almost no decline in electrical and mechanical properties after immersion in water, and good water resistance, electrical resistance and heat resistance. With the production of rubber With the development of technology, processing and other aspects, the amount of ethylene-propylene rubber in cable production is also increasing. The existing ethylene-propy...

[0002] In recent years, with the rapid development of China's economy, the contradiction of tight energy supply has become more and more prominent. In order to meet this demand, major coal mines have adopted high-power coal mining equipment to increase production capacity, and the supporting cables for power transmission Ethylene-propylene rubber insulation has high operational reliability and other advantages, such as high moisture resistance, almost no decline in electrical and mechanical properties after immersion in water, and good water resistance, electrical resistance and heat resistance. With the production of rubber With the development of technology, processing and other aspects, the amount of ethylene-propylene rubber in cable production is also increasing. The existing ethylene-propylene rubber materials are increasingly unable to meet the social needs of rapid development. How to prepare a temperature-resistant, tear-resistant Excellent performance, small compression deformation, low production cost, and good economic benefits have become technical problems that need to be solved at present.
