The invention relates to the technical field of tires, in particular to high-wear-resistance solid tire tread rubber and a preparation method thereof. The high-wear-resistance solid tire tread rubbercomprises the following raw materials in parts by weight: 40-60 parts of epoxidized natural rubber, 20-30 parts of butadiene rubber, 8-10 parts of tread rubber powder, 20-30 parts of white carbon black, 1-3 parts of white carbon black dispersant, 5-15 parts of coal tar resin, 1-3 parts of zinc oxide, 2-4 parts of stearic acid, 0.5-0.8 part of N-phenyl-2-naphthylamine, 1-3 parts of anti-aging agent, 5-10 parts of silane coupling agent, 8-15 parts of cashew nut shell oil, 1-2 parts ofsulphur, 0.2-0.5 parts of triethanolamine, 0.1-0.2 parts of phthalic anhydride, 1-3 parts of sorbitol, 2-6 partsof butyl methacrylate and 2-5 parts of N-hydroxymethyl acrylamide. According to the tire tread prepared from the high-wear-resistance solid tire tread rubber, the wear resistance and the puncture resistance of a tire are improved, and the surface strength and the tear resistance of the tire tread are excellent.
