Problems solved by technology

Many raw materials used in traditional tires can no longer meet the requirements of EU REACH regulations; and the tread compound formula, its wear resistance, safety and rolling resistance are intertwined and cannot achieve a comprehensive balance
For example, the use of super wear-resistant furnace black can improve the wear resistance of tread rubber, but the ensuing problem is that due to the fine particles of super wear-resistant furnace black, it is not easy to disperse in the rubber compound during the rubber mixing process, and will It will cause unevenness of the rubber material and reduce the performance of the rubber material; at the same time, due to the existence of the fine particles of furnace black, the tread rubber will have large rolling resistance and heat generation during the processing of semi-finished products, which will consume a lot of fuel and directly increase the transportation cost

Abstract

The invention relates to a formula of tire rubber, in particular to a rubber material formula of car tires. The rubber material formula of car tires, provided by the invention, is composed of following components in parts by weight: 110-140 parts of crude rubber material, 60-110 parts of reinforcing agent, 10-15 parts of environment-friendly aromatic hydrocarbon oil, 2-3 parts of activating agent, 2-4 parts of anti-aging agent, 1-2 parts of microcrystal wax, 2-5 parts of accelerator and 2-2.5 parts of vulcanizing agent. The tires prepared by the rubber material formula disclosed by the invention have greatly improved safety and reduced oil consumption; and the design meets the requirements for environment protection, safety and energy saving of the car tires.

Description

Technical field [0001] The invention relates to a formula for tire rubber, in particular to a rubber compound formula for passenger car tires. Background technique [0002] The current tire tread rubber configuration mainly includes natural rubber, butadiene rubber, styrene butadiene rubber, reinforcing carbon black, leveling agent, zinc oxide, stearic acid, anti-aging agent, protective wax, accelerator, sulfur and anti-scorching agent, etc. . The tread rubber is in contact with the ground and requires abrasion resistance, impact mitigation, anti-skid, driving and braking functions. Many of the raw materials used in traditional tires can no longer meet the requirements of EU REACH regulations and other requirements; moreover, the wear resistance, safety, and rolling resistance of the tread rubber formula are mutually constrained and cannot achieve a comprehensive balance. For example, the use of super abrasion-resistant furnace black can improve the wear resistance of the tread...
