A low rolling resistance tire tread rubber composition and tire manufactured therefrom

Abstract

The present invention involves a low -rolling resistance tire tire rubber composition and the tires it manufactured. It is used for tires with a specification of 175 / 70R13Q and belongs to the field of tire technology.It contains the following weights: the natural rubber STR20 is 55 ~ 60, the dissolved polyette benzene phenylene SSBR4525 is 20-25, the bunand22EZ of the pupa is 15 ~ 20, the silver chrysanthemum glory is 5, the carbon black ECORAX1670 is 20 to 20 to 20 to 20~ 25. The white charcoal black Ultrasil 5000gr is 30 to 35; its preparation method is: to prepare by silver chrysanthemum, mixed refining machine, etc.The tire pattern design of patterns, knife groove patterns, etc., is made of low rolling resistance tires.The present invention provides a tire tire rubber composition and the tires they manufactured. By optimizing the formula of tire, improving the mixed craftsmanship, improving the tire pattern, and the organic combination of the three, the three ones are used to ensure the grip and wear resistance of the tire.At the same time as anti -hygroscopic slip, reducing tire rolling resistance.

Description

technical field [0001] The invention relates to a tire, in particular to a low-rolling-resistance tire tread rubber composition and the tire manufactured therefrom, and belongs to the technical field of tires. Background technique [0002] As we all know, with the vigorous development of the automobile industry, the depletion of fossil fuels, and the increasing awareness of environmental protection and energy conservation, how to reduce the fuel consumption of automobiles has become the focus of attention of the automobile industry. With the implementation of mandatory tire labeling regulations in the European Union in 2012, reducing tire rolling resistance has become a hot topic in the tire industry. The fuel consumption caused by tire rolling resistance accounts for 15% of the total fuel consumption. If the tire rolling resistance is reduced by 30%, the fuel consumption will be reduced by 4.5% %. Among all the components such as tread, sidewall, and carcass that make up t...

Problems solved by technology

[0003] Through scientific and technological literature search, it is found that most domestic and foreign tire companies are currently researching on one or two aspects of tread formula, preparation method and tread pattern to reduce tire rolling resistance, and seldom focus on optimizing tread formula, improving mixing process and improving tire tread pattern. The three aspects of the surface pattern are started at the same time, so that the three are organically combined to achieve the purpose of reducing the rolling resistance of the tire
