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

Abstract

The invention discloses a low-cost insulating rubber cable material and a preparation technology thereof. The low-cost insulating rubber cable material consists of the following components in parts by weight: 8-14 parts of chlorinated polyethylene, 15-21 parts of ethylene-octylene copolymer elastomer, 15-31 parts of modified calcination pottery clay, 5-8 parts of 80# paraffin base rubber oil, 0.5-1 part of active magnesium oxide, 4-7 parts of superfine talcum powder, 1-2 parts of active zinc oxide, 0.3-0.6 part of environment-friendly stabilizer, 1-2 parts of microcrystalline wax, 0.5-1 part of titanium dioxide, 0.5-0.8 part of 4,4' bis(alpha, alpha dimethyl benzyl) diphenylamine, 1-2 parts of dicumyl peroxide and 1-1.5 parts of triallyl cyanurate, wherein the mass fraction of the octylene monomer in the ethylene-octylene copolymer elastomer exceeds 20%. By adopting the low-cost insulating rubber cable material and preparation technology thereof disclosed by the invention, the inorganic powder is uniformly added, the technological range is wide, relatively high elongation at break is still kept when the continuous vulcanization temperature is 190-210 DEG C, and the cost is greatly reduced.

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. ...
