Problems solved by technology

[0003] With the popularization of the concept of green tires, the voice of designing environment-friendly tires is getting higher and higher. The introduction of EU labeling regulations has promoted tire companies to improve tire safety and reduce rolling resistance, thereby reducing fuel consumption of cars. The most effective way to improve rolling resistance is to use silica in the formulation. However, as silica is used in large quantities in tread compounds instead of carbon black, the tread becomes more prone to wear. As tire wear occurs, rubber A large amount of additives in the composition will be distributed in the air, and at the same time, a large number of tiny particles will be produced, causing the PM2.5 index to exceed the standard. Although the traditional formula design apparently reduces the rolling resistance of the tire, it actually loses the tire’s abrasion performance, and seriously pollute the environment

Abstract

The invention provides a tyre applying rubber composition. Silicon dioxide with high specific surface area and a sulfhydryl silane coupling agent are used simultaneously, rubber can be effectively reinforced through the silicon dioxide with high specific surface area, high wear resistance, low rolling resistance and high scratch performance of the rubber composition are achieved, crude rubber in the rubber composition adopts SSBR, NR and BR, SSBR and silicon dioxide are high in affinity, scattering of silicon dioxide in a rubber matrix is benefited, and rolling resistance of the rubber composition is reduced; meanwhile, dosage of sulfhydryl silane is controlled, compatibility between silicon dioxide with high specific surface area and the rubber can be effectively improved, and rolling resistance of the rubber composition is reduced beneficially; a tyre prepared from the tyre applying rubber composition is high in wear resistance, low in rolling resistance and high in scratch performance.
