Rubber composite for wear-resistant tire treads

Abstract

The invention provides a rubber composite for wear-resistant tire treads. The rubber composite is prepared from, by weight, 4-30 parts of natural rubber, 4-40 parts of butadiene rubber, 4-40 parts of styrene butadiene rubber, 35-75 parts of high-dispersion white carbon black, 3-10 parts of white mineral oil, 1.0-2.5 parts of indirect zinc oxide, 1.0-2.0 parts of stearic acid, 1.0-2.0 parts of rubber protecting wax, 1.0-2.8 parts of silane coupling agent, 1.0-2.0 parts of anti-aging agent, 1.0-2.0 parts of tackifying resin, 1.0-2.0 parts of dispersing agent, 1.0-2.8 parts of common sulphur, 0.5-2.0 parts of accelerant CZ, 1.0-2.0 parts of accelerant DPG and 0.1-1.0 part of accelerant DM, by proportioning according to the formula prior to mixing via an internal mixer. The rubber composite is mixed via the internal mixer by means of blending the natural rubber and the synthetic rubber as main materials which are matched with the high-dispersion white carbon black as a reinforcing agent and through unique anti-aging system design, and accordingly tire treads produced by the rubber composite are excellent in wear-resisting property, good in tear resistance and high in tensile strength, and service lives of tires for taxies, family cars and the like can be prolonged.

Description

technical field [0001] The invention relates to automobile tires, in particular to a rubber composition for wear-resistant tire treads. Background technique [0002] Existing passenger car tires generally have the disadvantages of poor wear resistance, and the tire tread is easy to cause pollution to the environment after wearing and falling off. How to improve the wear resistance of the tire tread and ensure that the tire tread meets the requirements of environmental protection is an important issue in the tire industry. [0003] Application number: 200710050386.7 Application date: 2007-11-01 Provided a high-wear-resistant aircraft tire tread rubber formula, the tread rubber is mainly made of natural rubber, with new technology, high-structure, high-wear-resistant carbon black, and high dispersion White carbon black, silane coupling agent, heat stabilizer are the main auxiliary materials, and zinc oxide, stearic acid, p-phenylenediamine anti-aging agent, ketone amine anti-...

AI Technical Summary

Problems solved by technology

[0004] Since the patent application uses natural rubber as the main material in the design process, the price of natural rubber is high and the aging resistance is poor. If the tire is used in the middle and late stages of the tire, abnormal wear will occur, which is not conducive to the long-term use of the tire; moreover Due to its high price, it has not been able to fully promote the use of
