Problems solved by technology

However, in order to obtain brightly colored rubber, compared with conventional black rubber, colored rubber cannot use polluting materials, especially polluting anti-aging agents. However, the rubber does not contain anti-aging agents. It is difficult to reach the level of traditional black rubber in protection
[0003] At present, colored tire tread compounds usually add more non-polluting chemical anti-aging agents for aging protection, but non-polluting chemical anti-aging agents have weak protection against ozone aging, especially dynamic ozone aging, and cannot achieve sufficient dynamic ozone aging protection effect; and after a period of use, the color rubber is prone to discoloration

Abstract

The invention provides a colorful rubber composition of a tire tread. The rubber composition of the tired tread of a colorful tire forms a main protective system through matrix rubber; through balancing section of the matrix rubber, basic usage performances of the rubber are guaranteed; tread rubber prepared by the rubber composition is colorful in appearance color, and is not liable to change color. According to the experimental results, vulcanizate properties and dynamic ozone aging characteristics of the obtained rubber composition can be kept to be free of racks within 48 hours under ozone concentration being 50 pphm; tensile strength can reach 18 MPa; and wear mileage of a tire prepared by the rubber composition provided by the invention can be more than 0.04 million km.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a tire tread rubber composition and an application thereof. Background technique [0002] Traditional car tires are usually black, not beautiful and unique in appearance. Using colored rubber to produce colored tires, the appearance is novel and unique, with great personality. However, in order to obtain brightly colored rubber, compared with conventional black rubber, colored rubber cannot use polluting materials, especially polluting anti-aging agents. However, the rubber does not contain anti-aging agents. It is difficult to reach the level of traditional black rubber in protection. [0003] At present, colored tire tread compounds usually add more non-polluting chemical anti-aging agents for aging protection, but non-polluting chemical anti-aging agents have weak protection against ozone aging, especially dynamic ozone aging, and cannot achieve sufficient dynamic ozone aging ...
