Embodiment
[0034] According to the conventional method in this field, the CPE base rubber is first kneaded on a small open mill, and after molding, the EPDM base rubber is added for mixing and masticating. After being fully mixed, all auxiliary materials except the vulcanizing agent and vulcanization aid are added for mixing. Refining, adding vulcanizing agent and vulcanizing aids after molding, kneading, uniform, cooling to obtain insulating rubber, and then insulating extrusion according to conventional methods to obtain mining cable rubber insulating rubber.
[0035] Shown below is the specific formula of each embodiment.
