Abstract

The invention relates to a rubber tire tread, and belongs to the field of preparation of rubber tires. The rubber tire tread is prepared from the following raw materials: polybutadiene rubber, brominated butyl rubber, natural rubber, polymeric borate ester fibers, nanometer montmorillonite, expanded graphite, sulfur, stearic acid and anti-aging agents, wherein the polymeric borate ester fibers can be used for effectively enhancing the strength of a tire and reducing the density of the tire. The rubber tire tread disclosed by the invention has the advantages of high abrasion resistance, anti-aging resistance, high frost crack preventing effect and low density.

Description

Technical field [0001] The invention relates to a rubber tire tread and belongs to the field of rubber tire preparation. Background technique [0002] In the past 10 years, China's automobile industry has entered a stage of explosive growth, especially with the improvement of living standards, the demand for private car purchases has begun to rise rapidly. As an important part of the car, the tire plays a role in supporting the weight of the vehicle, transmitting the torsion force of traction and braking, ensuring the adhesion of the wheel and the road, reducing and absorbing the vibration and impact of the car during driving, and preventing the auto parts from being severe Vibration and early damage play an important role in ensuring driving safety, handling stability and comfort. While ensuring the strength of the tire, it is often expected that it has a lower density, and a decrease in density will usually bring about a decrease in strength and wear resistance, thereby reduci...
