Wear-resisting rubber material for tires

Abstract

The invention discloses a wear-resisting rubber material for tires. The wear-resisting rubber material comprises the following raw materials in parts by weight: 45-50 parts of butadiene styrene rubber, 10-15 parts of butadiene rubber, 10-15 parts of natural rubber, 20-25 parts of isoprene rubber, 0.5-0.8 part of sulfur powder, 2-3 parts of accelerant nonanoyloxybenzene sulfonate (NOBS), 1.3-1.7 parts of accelerant DM, 0.5-0.9 part of accelerant tetramethyl thiuram monosulfide (TMTM), 10-15 parts of nano-cellulose whisker, 10-15 parts of barite powder, 20-23 parts of calcite powder, 7-9 parts of brucite powder, 5-8 parts of aluminium nitride, 30-35 parts of carbon black N234, 1-1.2 parts of single alkoxy titanate coupling agent, 1-1.2 parts of plasticizer dicyclohexyl phthalate (DCHP), 3-7 parts of octyl epoxy stearate, 0.3-1.2 parts of anti-aging agent 264, and 1-2 parts of anti-aging agent MB. The wear-resisting rubber material for the tires has excellent wear-resisting and ageing-resistant properties, so that the wear-resisting rubber material can adapt to the service environment of the tires, and the cost is also reduced.

Description

technical field [0001] The invention relates to the technical field of tire rubber materials, in particular to a wear-resistant tire rubber material. 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] The patent application number is 200710050386.7 provides a high wear-resistant aviation tire tread rubber formula, the tread rubber is made of natural rubber as the main material, with the addition of new technology high-structure high wear-resistant carbon black, highly dispersible white carbon black, silane Joint agent, heat stabilizer as the main auxiliary material, and then add zinc oxide, stearic acid, p-phenylenediamine anti-ag...

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
