Abstract

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.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a high wear-resistant solid tire tread rubber and a preparation method thereof. Background technique [0002] Car tires are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Tread is the only part of an automobile component that is in direct contact with the road surface. Therefore, it is closely related to the safety, comfort and energy saving of the car during driving. The main function of the tread is to prevent the carcass from mechanical damage, transmit the traction and braking force of the vehicle, and buffer the impact of the tire during driving. Therefore, the tread is also required...
