Abstract

A disclosed anti-ageing shock-resistant modified butyl-rubber cable material comprises the following raw materials: butyl rubber, natural rubber, poly(4-methyl-1-pentene), stearic acid, zinc oxide, 2,5-dimethyl-2,5-di-(benzoyl peroxy)hexane, carbon black, carbon nanotube, modified white carbon black, polyethylene micro powder, 2,4-di-tert-butyl-6-cycloheximide phenol, 3,5-di-tert-butyl-4-hydroxylbenzyl methyl ether, promoter CZ, promoter TMTD, propanediol sebacate polyester, coumarone resin, di-(2-ethylhexyl)4,5-epoxy tetrahydrophthalate, N-[3-(trimethoxysilyl)propyl]ethylenediamine, isopropyl tri(dioctylpyrophosphate) titanate, and calcium stearate. The anti-ageing shock-resistant modified butyl-rubber cable material is fast in curing speed, high in strength, and excellent in ageing resistance and impact resistance.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to an aging-resistant and impact-resistant modified butyl rubber cable material. Background technique [0002] Butyl rubber is the fourth largest synthetic rubber in the world. It has excellent air tightness and good heat resistance, aging resistance, ozone resistance, solvent resistance, electrical insulation, shock absorption and low water absorption. , water tires, curing bladders, airtight layers, sidewalls, wires and cables, waterproof building materials, shock-absorbing materials, medicinal corks, etc. have a wide range of applications. However, due to the low amount of isoprene in butyl rubber, the vulcanization speed is low, which hinders the co-vulcanization of butyl rubber and other rubbers. In addition, butyl rubber will be subjected to high temperature, oxygen, and high pressure during production, processing and use. , solvents and other factors of corrosion and...
