Problems solved by technology

Chinese application number CN201110201496.5 and application number CN200810073676.8 tread rubber formula patents add anti-crack resin to improve the tear resistance of the tire. The difference in the compatibility of the rubber materials leads to poor dispersion of the rubber materials. The tear resistance of the natural rubber and synthetic rubber blends will be greatly reduced after heat aging, thereby reducing the performance of the tire.

Abstract

The invention discloses an engineering tire tread rubber composition. The engineering tire tread rubber composition mainly comprises rubber, carbon black, white carbon black, a white carbon black dispersant, operation oil, sulphur, a sulfuration promoter, a homogenizing agent and other additives. The engineering tire tread rubber composition has the characteristics of high modulus, high dispersity, excellent tear resistance, wear resistance, high mechanical aging coefficient and low hysteresis loss.

Description

technical field [0001] The invention relates to an engineering tire tread rubber composition, in particular to a formula of engineering tire tread rubber, and belongs to the technical field of engineering tire tread rubber. Background technique [0002] Mining trucks, trucks, dump trucks and other engineering vehicles have a large carrying capacity and need to drive on harsh road conditions such as mud, sand, and sharp ore. , Strong wear and tear on the road surface and other destructive effects. In addition, due to the high heat generation of the tire under high load, the tire is required to have good impact resistance, tensile strength, wear resistance, heat aging resistance and other properties. [0003] Improving the wear resistance and tear resistance of the rubber compound is an important factor related to the durability of the tire. The improvement of the wear resistance and tear resistance of the rubber compound will help to improve the cut resistance and tear resist...
