The invention discloses a wear-resistant and aging-resistant cable sheath material. The material is prepared from, by weight, 40-60 parts of ethylene propylene diene monomer rubber, 15-30 parts of polyamide 66, 10-20 parts of modified white mica powder, 2-5 parts of a wear-resisting auxiliary agent, 10-20 parts of semi-reinforced carbon black, 1-4 parts of a flame-retardant auxiliary agent, 1-2 parts of N-tertiary butyl-2-benzothiazole sulfenamide, 2-4 parts of N, N'-m-phenylene dimaleimide, 3-8 parts of stearic acid, 0.5-1 part of zinc dibutyl dithiocarbamate, 0.5-1 part of an anti-aging agent DPPD, 2-5 parts of white oil and 2-3 parts of fortifier DH-3. The wear-resistant and aging-resistant cable sheath material is good in mechanical strength, wear resistance, aging resistance, weatherability, impact elasticity, chemical corrosion resistance and excellent in electrical insulation property, and meanwhile the modified white mica powder is adopted, so that the processing property of the ethylene propylene diene monomer rubber is improved, and the obtained cable sheath material can be used in environments with various climatic conditions.
