Abstract

The invention discloses a cold-resistant rubber cable sheath material and a preparation method. The material comprises chlorinated polyethylene, ethylene-propylene-diene monomer (EPDM) rubber, lead oxide, calcium carbonate, N-isopropyl benzene-N'-phenyl p-phenylenediamine serving as an anti-aging agent, antimonous oxide, magnesium oxide, paraffin hydrocarbon oil, chlorinated paraffin, paraffin, carbon black, settled white carbon black, talc powder, gamma-aminopropyl triethoxysilane serving as a surfactant, dicumyl peroxide serving as a vulcanizing agent and triallyl isocyanurate serving as a co-vulcanizing agent. The low temperature performance of the material is improved by blending the chlorinated polyethylene and the EPDM rubber, and meanwhile, the flame-retardant performance of the rubber sheath material is improved by synergy of the antimonous oxide serving as a flame retardant and the chlorinated paraffin; experiments show that the rubber sheath material can pass low-temperature embrittlement test of 40 DEG C below zero, has excellent low-temperature resistance, has the oxygen index of more than 32 and has good flame-retardant performance; and the preparation method is simple and strong in operability.

Description

technical field [0001] The invention relates to a cold-resistant rubber cable sheath material, and also relates to a preparation method of the material. Background technique [0002] China has a vast land, which makes the climate very different, and the huge temperature difference puts forward higher requirements for our cable materials. The temperature in the northern region can often reach minus 40°C, and the general equipment is in an unattended area. Cables working under such conditions should have good low temperature resistance and certain flame retardancy. General plastics, chlorinated poly Vinyl rubber doesn't work well at these low temperatures. Contents of the invention [0003] The first object of the present invention is to provide a rubber cable sheath material with excellent low temperature resistance and flame retardancy; [0004] The second object of the present invention is to provide a preparation method of the above-mentioned rubber cable sheath materi...
