Abstract

The invention belongs to the technical field of tires, and in particular relates to a tire tread compound material and a preparation method thereof. The tire tread compound material is prepared by performing first-stage mixing, second-stage mixing and a vulcanizing process on natural rubber, styrene-butadiene rubber, carbon black, a rubber modifier, white carbon black, zinc oxide, stearic acid, an anti-aging agent RD, an anti-aging agent 4020, anti-cracking resin, a plasticizer A, type B microcrystalline wax, sulfur, a promoter NS, a promoter HMT and an anti-scorching agent CTP. In a formula system of the tire tread compound material disclosed by the invention, a combination system of the natural rubber and the styrene-butadiene rubber is used, a double reinforcement system of the carbon black and the white carbon black is used, the anti-cracking resin improves the tear resistance of the tread compound material, the rubber modifier increases the wear resistance of the tread compound material, and the promoter HMT is added into a vulcanization system to improve the activity of the white carbon black, so that the white carbon black achieves better reinforcement and anti-cracking effects in the tread compound material.

Description

technical field [0001] The invention belongs to the technical field of tires, and in particular relates to a tire tread compound and a preparation method thereof. Background technique [0002] The tread rubber requirements of mine pattern tires are different from those of ordinary tires. The road conditions of mine pattern tires are poor, the speed is slow, and the load capacity is large. Therefore, the tread rubber of mine pattern tires requires good puncture resistance and tear performance. When ordinary truck tire tread rubber is used on mine tread tires, it is easy to cause the tire pattern blocks to tear and fall off. Contents of the invention [0003] The purpose of the present invention is to provide a rubber tread compound for tires, which improves the tear resistance and wear resistance; the invention also provides a preparation method for the tread rubber compound for tires, which is scientific, reasonable, simple and easy to implement. [0004] The tire tread c...
