USE - The chlorinated polyethylene rubber is useful for manufacturing wind energy cable.    ADVANTAGE - The chlorinated polyethylene rubber is suitable for wide range of temperature, has good performance and long service life.    DETAILED DESCRIPTION - Chlorinated polyethylene rubber for manufacturing wind energy cable comprises (in parts) chlorinated polyethylene (100-110), magnesium oxide (10-15), tribasic lead sulfate (1-2.5), lead stearate (1-3), stearic acid (0.5-1.5), high wear-resisting carbon black (15-25), flame retardant (1-3), dioctyl phthalate (15-20), chlorinated paraffin (20-33), light calcium carbonate (10-13), cross-linking agent (1.5-3.6), auxiliary crosslinking agent (2-3.6), antioxidant (1-3), paraffin oil (2-5), zinc oxide (2-3.5), plasticizer (2-4), diantimony trioxide (0.5-2), zinc borate (0.5-1), basic magnesium carbonate (3-6), epoxy soybean oil (2-6), decabromodiphenyl ether (13-18), antimony oxide (18-25), UV resistant agent (2-5) and organic modified bentonite (1-5). An INDEPENDENT CLAIM is also included for preparing the chlorinated polyethylene rubber comprising mixing and stirring all the materials along with crosslinking agent and auxiliary crosslinking agent, and stirring uniformly, using internal mixer to mix for 45-60 minutes at 65-80 degrees C, then adding the cross-linking agent and auxiliary crosslinking agent, continuously mixing for 1-3 minutes, discharging the adhesive material from the mixer, opening mill and packing the finished product. The vulcanization conditions for the cable are: the pressure is 8-10 MPa, the temperature is 160-170 degrees C and the time is 15-20 minutes.
