Cold-resistant flame-retardant sheath rubber for cable of electric welding machine

The invention discloses cold-resistant flame-retardant sheath rubber for a cable of an electric welding machine. The cold-resistant flame-retardant sheath rubber is prepared from the following components: 100 parts of chlorinated polyethylene, 8 to 15 parts of active agent, 3 to 5 parts of environment-friendly stabilizer, 3 to 5 parts of microcrystalline wax, 5 to 10 parts of environment-friendly antimonous oxide, 60 to 100 parts of reinforcing filler, 15 to 30 parts of plasticizer, 0.5 to 1.5 parts of anti-ageing agent RD, 0.3 to 0.5 part of antioxidant 1010, 0.6 to 1.2 parts of coupling agent A-172, 2 to 4 parts of vulcanizing agent DCP and 2 to 4 parts of vulcanizing aid TAIC. The rubber content of the sheath rubber is 38 to 45 percent and is the weight/total weight*100% of the chlorinated polyethylene. The performance of the sheath rubber meets the performance requirement of GB/T5013.6-2008 'the Sixth Part: Cable of Electric Welding Machine of Rubber Insulating Cable with Rate Voltage of 450/750V and belo
