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 rubber composition for tire treads and applications thereof. Background technique [0002] Traditional car tires are usually black, which is not beautiful and unique in appearance. The use of colored rubber to produce colored tires has a novel and unique appearance, and is very individual. However, in order to obtain a brightly colored rubber compound, compared with the conventional black rubber compound, the color rubber cannot use polluting materials, especially polluting antioxidants. However, the rubber compound does not contain antioxidants, which is better in performance and ozone aging. It is difficult to reach the level of traditional black rubber in protection. [0003] At present, color tire tread compounds usually add more non-polluting chemical antioxidants for aging protection, but non-polluting chemical antioxidants have weak protection against ozone aging, especially dy...
