The invention discloses environmentally-friendly cutting-resistant off-the-road tyre tread rubber. The environmentally-friendly cutting-resistant off-the-road tyre tread rubber comprises, by weight, 100 parts of natural rubber, 45-65 parts of N115 carbon black, 1-3 parts of aramid short fibers, 0.5-3.5 parts of environmentally-friendly aromatic oil, 3-7 parts of zinc oxide, 0.5-2.5 parts of stearic acid, 0.5-2.5 parts of N-isopropyl-N-phenyl-para-phenylene diamine, 0.5-2.5 parts of 2,2,4-trimethyl-1,2-dihydroquinoline polymer, 0.5-2.5 parts of protection wax, 0.8-1.2 parts of sulphur, 0.5-1.7 parts of N-cyclohexyl-2-benzothiazolylsulfenamide and 0.1-0.5 parts of an anti-scorching agent CTP. The environmentally-friendly cutting-resistant off-the-road tyre tread rubber satisfies REACH regulations, has the characteristics of excellent cutting resistance, wear resistance and collapse resistance and realizes good balance between toughness, a thermogenesis value, heat aging resistance and wear resistance.
