Problems solved by technology

Due to the high viscosity of EPDM, the semi-conductive shielding material needs to be filled with a sufficient amount of conductive carbon black to realize its function, so the processing performance of the semi-conductive shielding material is not good, and the price is not low

Abstract

The invention relates to a semiconductor shielding cable material, and belongs to the technical field of cable materials. The semiconductor shielding cable material comprises the following components in parts by weight: 100 parts of butyl rubber, 50-120 parts of conducting carbon black, 20-45 parts of plasticizing agent, 1.0-6.0 parts of vulcanizing agent, 1.0-6.0 parts of co-vulcanizing agent, 1.0-10 parts of activating agent, 0.2-0.5 part of coupling agent, and 0.5-5.0 parts of anti-aging agent. The semiconductor shielding cable material has the advantages that the formula not only is low in cost, but also is simple in component; the butyl rubber with low cost, low viscosity and high fallibility is adopted as a base material, the vulcanization system matched with the butyl rubber is selected, and the conducting carbon black with good conductivity and processing performance is added, so that the defects of bad processing performance and high price in the prior art are overcome.

Description

technical field [0001] The present invention relates to a semiconductive conductor shielded cable material, more specifically, the present invention relates to a semiconductive conductor shielded cable material for medium voltage rubber sheathed cables, especially a rubber type high temperature resistant halogen-free semiconductive conductor shielded cable A material belongs to the technical field of cable materials. Background technique [0002] Medium-voltage rubber-sheathed cables, including marine cables, oil platform cables, and mining cables, all require semi-conductive conductor shielding cable materials. The basic rubber in the prior art mainly uses ethylene-vinyl acetate resin. For example, the Chinese invention patent application No. 201110407899.5 discloses a peelable semi-conductive shielding with ethylene-vinyl acetate resin and chlorinated polyethylene as the base material. material. Although the elasticity is improved with the increase of vinyl acetate conte...
