High pressure rubber insulated cables use peelable insulation shielding material, calculated according to the quality, the components are: 100 chlorinated polyethylene, 30-50 acetylene carbon black, 1-2 antioxidant, 3-4 organic peroxide, 4-5 acceletator, 1-2 coupling, 10-20 magnesium oxide, 1-1.5 stabilizer, 4-8 methyl silicone, 4-5 alkaline neutralizing, 30-40 processing oil. This invention overcomes the problem that the existing technology cannot produce high voltage mine rubber insulation cable use peelable insulation shielding material technology, this material has excellent conductivity, volume resistivity less than 40Ω.cm, tensile strength can reach more than 15MPa, peel strength controls in 8-40N/1cm, can be long-time used in 90℃.With the pelletizing system, pelletize in the hot situation, then carry out water, particle uniformity, section roundness, no debris, good particles appearance, without drawing process, don’t need to worry about the broken wire drawing pelletizing process, reduce the labor.
