Abstract

The invention discloses a special sidewall rubber composition for white sidewalls, which is prepared from the following raw materials in parts by weight: 100 parts of rubber; 10-80 parts of reinforcing filler; 3-8 parts of anti-aging agent; plasticizer 2-20 parts, active agent 1-6 parts; accelerator 2-5 parts; vulcanizing agent 1-6 parts. The invention keeps the physical and mechanical properties of the sidewall formula unchanged, and improves the ability of anti-discoloration, anti-pollution and anti-aging after it is compounded with white or colored sidewalls.

Description

Technical field [0001] The invention relates to the technical field of tire manufacturing, in particular to a sidewall rubber composition special for white sidewalls. Background technique [0002] With the improvement of living standards and the pursuit of personalized lifestyles, people's requirements for tires equipped with vehicles have changed. People no longer only pursue tire quality. There are more and more white side tires and colored tires with different colors. Appear in the people's vision. [0003] Color tires are the product of color rubber or white rubber compounded with traditional normal sidewalls. However, the problem of discoloration of traditional white or colored sidewalls during use has become more and more prominent, and the discoloration directly affects the appearance of the tire. Affect customer experience. [0004] This project is mainly to study the discoloration of white sidewall and colored sidewall tires. In view of the above problems, the traditional ...
