Abstract

The invention provides cable sheath rubber, which is characterized in that the raw material comprises 100 weight parts of chlorinated polyethylene, 2 to 6 weight parts of organic peroxide vulcanizing agent, 3 to 6 weight parts of sulfurization assisting agent, 0.5 to 1.5 weight parts of antiaging agent, 10 to 30 weight parts of fire retardant and 20 to 40 weight parts of reinforcing agent. The product has high fuel oil resistance, high mineral oil resistance, high resistance to low temperature after aging; the cable sheath rubber can be filled with more filler and has high compression deformation performance and toughness; and the smooth appearance of the rubber has high processing technical performance and high flame retarding performance.

Description

technical field [0001] The invention relates to a cable sheath rubber, which belongs to the technical field of rubber. Background technique [0002] The main use of chlorinated polyethylene (CM / CP) abroad is to make cables. CM has properties similar to those of chloroprene and chlorosulfonated polyethylene, but CM is not easy to burn, has good processability, and has no sticking phenomenon. CM has good stability to chromic acid, sodium hypochlorite and strong oxidizing chemicals, and has good resistance to mineral oil. The chlorine content of commonly used CM is between 30% and 40%, which has rubber-like characteristics. With the increase of chlorine content, the extrusion performance, oil resistance, wear resistance and flame retardancy of CM are improved accordingly, while the elasticity and cold resistance sex decline. Contents of the invention [0003] The object of the present invention is to provide a cable sheath rubber with good fuel oil resistance, mineral oil...
