UHPT tread rubber which can be used in drifting competition

Abstract

The invention discloses UHPT tread rubber which can be used in a drifting competition. The tread rubber comprises the following components: emulsion polymerized styrene-butadiene rubber 50-70 phr, solution polymerized styrene-butadiene rubber 30-50 phr, carbon black 50-80 phr, white carbon black 20-50 phr, a silane coupling agent 2-5 phr, oil 30-50 phr, functional resin 8-16 phr, zinc oxide 2-4 phr, stearic acid 1-3 phr, sulfur 1.5-2.5 phr, an accelerator 2.0-3.0 phr, and other components 4-7 phr. The formula of the tread rubber provided by the invention innovatively uses the modified solutionpolymerized styrene-butadiene rubber, the highly-dispersed white carbon black with a high specific surface area and the functional resin, also the ratio of fillers and the mixing process of the treadrubber are reasonably adjusted, and the requirements of the usage performance of daily driving and the drifting competition are taken into account: compared with ordinary UHPT tread rubber, the treadrubber provided by the invention has excellent dry ground gripping and manipulating performance; and compared with professional drifting tread rubber, the tread rubber provided by the invention has significantly-improved service life and better-improved wet ground gripping performance, and can meet multi-purpose requirements of usual driving and the drifting competition.

Description

technical field [0001] The invention belongs to the technical field of automobile tire materials, and in particular relates to a UHPT tread rubber which can be used in drift competitions. Background technique [0002] Tires are the only part of the car that is in contact with the road surface. When the car is running, the traction or braking force is transmitted through the contact between the tread and the ground. Automobile racing has always been an important sport to promote the development of tire technology, and major tire companies have relatively large research and development strength and capital investment in the field of racing tires. In recent years, car drifting has developed rapidly at home and abroad due to its super ornamental value, and its influence is increasing day by day. Attracted by speed and passion, many thrill-seeking consumers are eager to try drifting competitions, but the threshold of expensive and luxurious professional competitions is difficult...

AI Technical Summary

Problems solved by technology

Attracted by speed and passion, many thrill-seeking consumers are eager to try drifting competitions, but the threshold of expensive and luxurious professional competitions is difficult for ordinary people to surpass. Some sports cars and modified cars have adapted to this market. The sudden rise of professional competitions

Professional drifting tires have strict requirements on grip performance and handling performance, but the tire life is generally only tens or hundreds of kilometers, which cannot be compared with the tens of thousands of kilometers of ordinary UHPT tires, and the wet grip performance is average. Driving safety on slippery roads cannot be guaranteed, not suitable for daily driving, and requires frequent tire replacement

However, the grip and handling performance of ordinary UHPT tires cannot meet the needs of drifting driving, and are not suitable for racing.
