Abstract

The invention discloses a high-performance rubber material for cable sheaths, which is prepared from the following raw materials in parts by weight: 40-55 parts of styrene-butadiene rubber, 30-35 parts of ethylene propylene diene monomer rubber, 15-25 parts of natural rubber, 5-6.8 parts of zinc oxide, 2-3 parts of stearic acid, 1.4-1.8 parts of dicumyl peroxide, 10-15 parts of sorbic acid, 5-8 parts of argil, 5-8 parts of coupling agent, 10-18 parts of kaolin, 15-25 parts of modified purple carbon black, 5-13 parts of silica white, 30-45 parts of silicon dioxide, 15-25 parts of spiral nano carbon fiber, 0.8-1.2 parts of accelerator TMTD, 0.4-0.6 part of accelerator ZDC, 5-15 parts of magnesium methacrylate, 3-6 parts of heat-resistant agent LiCO3-50, 3-5.8 parts of microcapsulated red phosphorus, 3-8 parts of anti-aging agent GM and 0.8-1.8 parts of microcrystalline wax. The raw materials are plasticized, mixed and vulcanized to obtain the high-performance rubber material for cable sheaths, wherein the vulcanizing temperature is 145-155 DEG C, the vulcanizing pressure is 15-18 MPa, and the vulcanizing time is 25-35 minutes. The high-performance rubber material for cable sheaths has the advantages of high strength, high wear resistance and high flame retardancy.

Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a high-performance rubber material for cable sheaths. Background technique [0002] The rapid development of society has brought opportunities and challenges to power cables. With the development of wind power, aviation and oil fields, the performance requirements of power cables are getting higher and higher. First of all, power cables are mostly used in areas with harsh weather conditions, where the temperature is cold and the temperature difference between day and night is large, so they should have good low temperature resistance, excellent UV resistance and weather aging resistance; secondly, cables are divided into mobile and fixed installation cables according to the application occasions. , mobile cables need to be twisted frequently, and should have good torsion resistance and bending performance; again, electrical cables are sometimes exposed to oil, and will be c...
