Abstract

The invention discloses cable sheath rubber, and the cable sheath rubber belongs to the field of cable manufacture, and is prepared from chloroprene rubber, a vulcanizing agent, a vulcanizing agent assistant, lead sulfate tribasic, a plasticizer I, a plasticizer II, carbon black, white carbon black, a reinforcing agent, antimonous oxide, zinc borate, stearic acid, 2, 2-dithio-dibenzo thiazole, 2, 2, 4-trimethyl-1, 2-dihydrogenated quinoline polymer, N, N nickel dibutyl dithiocarbamate dibutyl and an anti mildew agent according to a certain mass ratio. The chloroprene rubber is preferably to be middle mooney viscosity type, the vulcanizing agent is preferably to be high activity magnesium oxide, the vulcanizing agent assistant is preferably to be dipentamethylenethiuram tetrasulfide, the plasticizer I is preferably to be microcrystalline wax, the plasticizer II is preferably to be dioctyl sebacate, the reinforcing agent is preferably to be diatomite, and the anti mildew agent is preferably to be o-phenyl phenol. The cable sheath rubber can meet the high flexibility and high wear resistance requirements of flexible cable sheaths, and has the high tear resistant, low temperature resistant, and anti-mildew properties. The invention also discloses a preparation method of the cable sheath rubber.

Description

technical field [0001] The invention relates to a cable sheath rubber and a preparation method thereof, belonging to the field of cable manufacturing. Background technique [0002] Under hot and humid conditions, rubber products are easy to breed various molds. Due to the growth and spread of molds, the internal molecular structure of rubber products will be destroyed, the physical properties will be affected, and even the function of use will be lost in severe cases. There is a serious threat to the safe operation of the cable. [0003] On November 18, 2009, Chinese invention patent application CN101580606A disclosed a cable sheath rubber and its preparation method. The cable rubber base material is composed of 30-50WT% natural rubber and 50-70WT% butadiene rubber; the rubber compound The vulcanization system in the agent is: low-sulfur high-accelerator vulcanization system, the amount of sulfur added is 0.3-0.6WT% of the rubber base material, the accelerator tetramethylth...
