Abstract

The invention discloses wear-resistant heat-resistant tire tread rubber. The prepared tire tread rubber has relatively good mechanical properties, wear resistance and heat resistance and is outstanding in quality and long in service life; carbon black has relatively high surface activity, is difficult to disperse during milling of rubber and is prone to aggregation to form an aggregate, and thus,comprehensive properties of a composite are weakened; and the carbon black is firstly treated with sodium hydroxide to form micro-etched dots on the surface of the carbon black, then, zirconium oxychloride, sodium metaphosphate and Span are added, then, ammonia water is dropwise added and reacts with the zirconium oxychloride to produce zirconium hydroxide, the sodium metaphosphate and the Span are adsorbed to the micro-etched dots, the attachment of the zirconium hydroxide to the micro-etched dots is promoted, and zirconium dioxide is produced on the surface of the carbon black after roasting, so that the probability of contact among homogeneous filler granules of the carbon black is lowered, the dispersion of fillers is improved, uniform stress concentration points are formed in a rubbermatrix, and mechanical properties of the composite are obviously improved.

Description

technical field [0001] The invention belongs to the technical field of rubber, in particular to a wear-resistant and heat-resistant tire tread rubber. Background technique [0002] As an important part of a car, tires play a role in supporting the weight of the vehicle, transmitting traction and braking torque, ensuring the adhesion between the wheel and the road surface, reducing and absorbing the vibration and impact of the car while driving, and preventing the car parts from being violently shaken. It plays an important role in ensuring driving safety, handling stability and comfort. The tire tread rubber is a layer of rubber material on the outermost layer of the tire that is in contact with the road surface and printed on the surface. It is usually rubber, which can make the tire have traction, buffer the impact and swing during driving, and prevent the cord layer from being cut and damaged. Piercing, etc., its role is also very important. [0003] In the preparation ...
