Abstract

The invention provides a wet-skid-resistant rubber composition as well as a mixing method and application thereof. The wet-skid-resistant rubber composition is prepared from the following components in parts by weight: 137.5 parts of oil-extended solution polymerized styrene-butadiene rubber, 30-60 parts of carbon black, 30-60 parts of white carbon black with a high specific surface area, 30-60 parts of white carbon black with a low specific surface area, 2-6 parts of a silane coupling agent, 40-90 parts of environment-friendly oil, 5-20 parts of functional resin, 2-5 parts of zinc oxide, 1-3 parts of stearic acid, 4-9 parts of an anti-aging agent, 1-2.5 parts of sulfur and 2-5 parts of an accelerant. Through special design of a formula system in the invention, the wet-skid-resistant rubber composition is used for tire tread rubber used for wet slippery racing tracks, so tires are allowed to have excellent gripping performance in different rainy-day racing track environments such as wet pavements and waterlogged pavements, and an effective solution is provided for coping with the varied rainy-day racing track environments in automobile racing competitions.

Description

technical field [0001] The invention relates to the technical field of automobile tire materials, in particular to an anti-wet skid rubber composition, a mixing method and application thereof. Background technique [0002] Motor racing is a sport that emerged in the 1930s. After decades of development, motorsports has developed into a vigorous sports industry. At present, hundreds of countries and billions of people in the world watch auto races every year through live, TV, and the Internet. Motorsports can be divided into drifting, rallying, racing, etc. Among them, racing events have the largest audience and are the most popular. Racing events are a kind of field races, that is, competitions on a prescribed track. In sunny weather and on dry tracks, slick tires are usually used to meet the grip performance requirements of the tires under the limit state of the vehicle; on wet and slippery tracks in rainy weather, it is required to replace patterned tires—rain tires to e...
