Problems solved by technology

[0002] Commonly used in rubber insulation is EPDM as the base material, with vulcanizing agent DCP and vulcanization accelerator TAC. The disadvantage of the compound rubber is: the elongation at break is low (the elongation at break is generally 150%~250%) , the process range in the vulcanization process is narrow, and it is easy to break and the elongation rate is unqualified during steam vulcanization

Abstract

The invention discloses a high-strength high-elongation flame retardant rubber insulated cable material and a preparation process thereof. The high-strength high-elongation flame retardant rubber insulated cable material comprises the following components in parts by weight: 8-14 parts of chlorinated polyethylene (CPE), 15-21 parts of ethylene-octylene copolymer elastomer (POE), 3-6 parts of fumed silica, 15-19 parts of aluminium hydroxide, 13-18 parts of calcined clay, 5-8 parts of 800# paraffin base rubber oil, 0.5-1 part of active magnesium oxide, 4-7 parts of superfine talcum powder, 1-2 parts of zinc oxide, 0.3-0.6 part of environmental 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. By adopting the high-strength high-elongation flame retardant rubber insulated cable material, uniform addition of inorganic powder is facilitated, a process range is wide, higher elongation at break is still maintained when a continuous vulcanizing temperature is 190-210 DEG C, a fire retardant and a high reinforced filler are added without reducing electrical property, and tensile strength and oxygen index are greatly increased; and cost is greatly reduced.

Description

technical field [0001] The invention relates to a high-strength resistance and high elongation flame-retardant rubber insulating cable material, and also relates to a preparation process of the high-strength resistance and high elongation flame-retardant rubber insulating cable material. Background technique [0002] Commonly used in rubber insulation is EPDM as the base material, with vulcanizing agent DCP and vulcanization accelerator TAC. The disadvantage of the compound rubber is: the elongation at break is low (the elongation at break is generally 150%~250%) , The process range in the vulcanization process is narrow, and the elongation at break is easy to fail during steam vulcanization. Contents of the invention [0003] The first object of the present invention is to provide a high-strength and high-elongation flame-retardant rubber insulating cable material, which is conducive to the uniform dispersion of inorganic powder, a wide range of processes, and a continuou...
