Abstract

The invention discloses a self-cleaning light-color sidewall rubber composition which comprises 5.0-35.0 parts of natural rubber, 40.0-70.0 parts of brominated isobutylene p-methylstyrene rubber, 10.0-40.0 parts of ethylene propylene diene monomer, 20.0-60.0 parts of kaolin, 20.0-60.0 parts of titanium dioxide, 0.5-3.0 parts of ultramarine, 0.5-2.0 parts of stearic acid, 2.0-4.0 parts of a chemical antioxidant, 1.0-10.0 parts of nano-zinc oxide, 0.5-3.0 parts of a vulcanizing agent, and 2.0-5.0 parts of anaccelerant. Through adjustment of a raw rubber system and a protection system, the self-cleaning function of the light-color sidewall rubber composition is realized by utilizing a phenomenon that a surface layer is easy to fall off due to slight ozone aging while conventional physical andmechanical performance requirements such as aging resistance and the like is guaranteed.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a sidewall rubber composition. Background technique [0002] With the maturity of radial tire technology, the competition in the tire market is becoming increasingly fierce, and the pace of product upgrading and new product development is also accelerating. While improving key competitive factors such as product quality and price, personalized tire appearance has also become a bright spot to attract consumers. The design of light-colored sidewall tires is just adapting to this situation. [0003] In addition to meeting the conventional anti-pollution, anti-discoloration and physical and mechanical performance requirements, the light-colored sidewall rubber composition should also have self-cleaning properties to reduce maintenance costs for consumers during use. Light-colored sidewall tires are exposed to environmental factors such as ultraviolet radiation and sand scra...
