Abstract

The invention discloses an anti-tear compression-resisting cable sheath material for coal mine, and the material is prepared by the following steps: terpolymer EP rubber, an ethane-butylene elastomer and chlorinated polyethylene which are used as base materials are plasticated for 2-4 minutes; a carbon black N330, nanometer silica, activated zinc oxide, a silane coupling agent, an antioxidant 4,4-bis(2,2-dimethyl benzyl)diphenylamine, eleaostearic acid, paraffin oil, microcrystalline paraffin, a promoter M, a promoter TMTD and a flame retardation system are mixed uniformly and discharged, and the mixing temperature is 115-121 DEG C; 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane and a crosslinking active auxiliary agent triallyl isocyanurate are sulfurated, the sulfuration temperature is 155-165 DEG C, the sulfuration time is 1-2 minutes, after discharging and cooling, the anti-tear compression-resisting cable sheath material for coal mine is obtained. The anti-tear compression-resisting cable sheath material for coal mine has the advantages of heatproof performance, excellent anti-tear performance, low anti-compression deformation, low production cost and good economic benefit.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials for coal mines, in particular to a tear-resistant and compression-resistant cable sheath material 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...
