Problems solved by technology

[0003] At present, the sports tires used in the domestic market are mainly racing tires and dry tires. However, racing sports in China are of a leisure and entertainment nature. Most racing enthusiasts say that these tires are only suitable for racing. However, there are still disadvantages such as high heat generation and high fuel consumption, and there are inevitably disadvantages such as cumbersome replacement and high price during use.

Abstract

The invention relates to a rubber composition used for tread positions of sport tires suitable for highways and drifting racing. The rubber composition is characterized by being composed of, by weight, 100-137.5 parts of styrene butadiene, 40-70 parts of carbon black, 20-30 parts of white carbon black, 1.5-2.5 parts of zinc oxide, 0.5-1.5 parts of stearic acid, 0.5-1.5 parts of homogenizing agent, 2-3 parts of Si-69, 1.5-2.5 parts of static protective agent, 1.5-2.5 parts of antiager, 1-3 parts of promoter, 1-3 parts of sulfur and 0.1-0.3 part of antiscorcher. The rubber composition takes requirements on performance in two aspects into consideration, has excellent wet land performance and dry land holding power and realizes harmonization of high controlling performance and low rolling resistance.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a rubber composition for road and drift sports tread parts. Background technique [0002] Tires are the only parts of a car that are in contact with the road. The mobility of a car needs to be achieved by transmitting force to the ground through the tires, so the performance of the tires directly affects the performance of the car. According to tire performance, adaptability to road conditions and other special purposes, there are quite strict specification divisions. Among them, the European labeling law is divided into three levels: C1 / C2 / C3, of which C1 includes car tires, and C3 includes special-purpose tires (such as racing tires) ). At present, major tire companies have invested considerable R&D efforts in all-weather and multi-purpose fields, such as all-season tires, road and drift dual-purpose sports models, etc. This kind of sports tire with excellent comprehensive p...
