The invention discloses a wear-resistant tread rubber, belonging to the technical field of polymer materials. The wear-resistant tread rubber is prepared through the following steps: successively weighing the following components by weight: 100 to 120 parts of mixed rubber, 3 to 6 parts of an anti-aging agent, 20 to 30 parts of carbon black, 7 to 9 parts of a plasticizer, 3 to 4 parts of zinc oxide, 2 to 4 parts stearic acid, 4 to 8 parts of a vulcanizing agent and 30 to 40 parts of a wear-resistant filling material, mixing the mixed rubber with the wear-resistant filling material in an open mill, carrying out open mixing for 30 to 60 minutes so as to obtain a mixed material, mixing the mixed material with the anti-aging agent in a mixing mill, successively adding the carbon black, the plasticizer, the zinc oxide and the stearic acid into the mixing mill, carrying out mixing for 20 to 50 minutes so as to obtain a blank material, mixing the blank material with the valcanizing agent, andcarrying out mixing and vulcanizing for 10 to 20 min so as to obtain the wear-resistant tread rubber. The wear-resistant tread rubber prepared according to a technical scheme of the invention has thecharacteristic of excellent wear resistance and has broad prospects in development of a vehicle polymer material technological industry.
