Tire tread rubber for low-rolling-resistance high-controllability semi-steel high-performance radial tire

Abstract

The invention relates to tire tread rubber for a low-rolling-resistance high-controllability semi-steel high-performance radial tire, and a processing technology of the tire tread rubber. The rubber is suitable for producing the semi-steel high-performance radial tire. According to a technical scheme provided in the invention, a formula of the rubber mainly comprises following components: natural rubber with a trademark being SCR5#, solution polymerized butadiene styrene rubber D756B, stearic acid, activated zinc oxide, an antioxidant 4020, an antioxidant RD, carbon black N2340, white carbon black with a trademark being ULtrasil VN3, a silane coupling agent with a trademark being JH-S69C, a promoter CZ, a promoter D, insoluble sulfur IS-6005 and an anti-scorching agent CTP. The formula employs a raw rubber system in which the nature rubber coexists with the solution polymerized butadiene styrene rubber and employs a novel material which is the solution polymerized butadiene styrene rubber D765B. The tire tread rubber produced according to the formula is stable in producing process. Both of rolling resistance and controllability of a finished tire can reach a relatively good level.

Description

technical field [0001] The invention relates to a semi-steel radial high-performance tire tread rubber with low rolling resistance and high controllability and a processing technology thereof. The rubber material is suitable for the production of semi-steel radial high-performance tires. Background technique [0002] In order to allow consumers to consume clearly, the European Union passed the "General Motor Vehicle Safety Regulations" (661 / 2009) in July 2009. The regulations put forward minimum requirements for passenger car, light truck and truck tires. Only through the use of tire labels Only when consumers fully understand the characteristics of tires can they maximize tire safety, reduce CO2 emissions, and reduce noise. In November 2009, the European Union passed the "Tire Labeling Regulations" (1222 / 2009), which stipulates that tire manufacturers must Provide consumers with some information on the performance of tires, and within the specified period must meet the mini...

[0002] In order to allow consumers to consume clearly, the European Union passed the "General Motor Vehicle Safety Regulations" (661 / 2009) in July 2009. The regulations put forward minimum requirements for passenger car, light truck and truck tires. Only through the use of tire labels Only when consumers fully understand the characteristics of tires can they maximize tire safety, reduce CO2 emissions, and reduce noise. In November 2009, the European Union passed the "Tire Labeling Regulations" (1222 / 2009), which stipulates that tire manufacturers must Provide consumers with some information on the performance of tires, and within the specified period must meet the minimum requirements of Regulation (EC) 661 / 2009 on rolling resistance, noise and wet grip of tires. These three performances correspond to tires respectively. Fuel-saving efficiency, comfort performance and safe handling performance, and the three performances of tires are mutually influencing, improving the fuel-saving efficiency of tires will reduce the safety performance of tires, and improving the safety performance of tires will affect the comfort of tires sex
