The invention relates to a high-wear-resistant irradiation crosslinked halogen-free flame-retardant automotive wire cable material composed of the following components in parts by weight: high density polyethylene, an ethylene-vinyl acetate copolymer, an ethylene-vinyl acetate-carbon monoxide terpolymer, maleic anhydride grafted polyethylene, aluminum hydroxide, magnesium hydroxide, a phosphorus-nitrogen flame retardant, a silane coupling agent, a wear-resistant nano-powder, zinc borate, silicone master batch, zinc stearate, a fluorine processing auxiliary agent-PPA, an antioxidant, and trimethylolpropane trimethacrylate. The wear-resistant nano-powder comprises a main component of a nitrogen-silicon-oxygen compound, the melt flow index of high density polyethylene is 0.08-2 g/10 min, the content of vinyl acetate in the ethylene-vinyl acetate copolymer is 20-40%, and the melt flow index of the ethylene-vinyl acetate copolymer is 0.2-5 g/10 min. The high-wear-resistant halogen-free flame-retardant cable material has the characteristics of high mechanical strength, low smoke, no poison, excellent wear resistance, good high-temperature resistance, good oil resistance and the like, and has the tensile strength of more than 17 MPa and the elongation at break of more than 600%.
