Problems solved by technology

[0002] Commonly used in rubber insulation is EPDM as the base material, using the vulcanizing agent DCP and the vulcanization accelerator TAC. The disadvantages of the compound rubber are: the elongation at break is low, and the process range is narrow during the vulcanization process. If extruded When the temperature is too high, it is easy to break and the elongation rate is unqualified

Description

technical field [0001] The invention relates to a low-cost insulating rubber cable material and a preparation process thereof, and also relates to a preparation process of the low-cost insulating rubber cable material. Background technique [0002] Commonly used in rubber insulation is EPDM as the base material, using the vulcanizing agent DCP and the vulcanization accelerator TAC. The disadvantages of the compound rubber are: the elongation at break is low, and the process range is narrow during the vulcanization process. If extruded When the temperature is too high, it is easy to fail the elongation at break. Contents of the invention [0003] The first object of the present invention is to provide low-cost insulating rubber cable material, which is conducive to the uniform addition of inorganic powder, a wide range of processes, and a high elongation at break when the continuous vulcanization temperature is between 190 ° C and 210 ° C. It also greatly reduces costs. ...
