Tire tread rubber compound with low rolling resistance and tire made from tire tread rubber compound

Abstract

The invention relates to a tire tread rubber compound with low rolling resistance and a tire made from the tire tread rubber compound. The tire tread rubber compound comprises the following raw materials in parts by weight: 50-70 parts of natural rubber STR20, 0-30 parts of solution polymerized styrene-butadiene rubber SSBR4525, 0-20 parts of neodymium butadiene rubber BunaNd22EZ, 0-10 parts of guayule, 20-35 parts of carbon black ECORAX1670, 20-35 parts of white carbon black ULTRASIL 5000GR, 1.5-3.0 parts of a silane coupling agent Si69 and 0.2-0.4 part of a silane coupling agent KH580. A preparation method comprises the following steps: preparing guayule, mixing by adopting an internal mixer and mixing by adopting an open mill, thereby acquiring the tire tread rubber compound with low rolling resistance. Through the tread pattern design for circumferential pattern, transverse pattern, siping pattern, and the like, the tire with low rolling resistance is prepared. According to the tire tread rubber compound with low rolling resistance and the tire made from the tire tread rubber compound provided by the invention, the tread formula is optimized, the mixing technique is improved, the tread pattern is improved and the tread formula, the mixing technique and the tread pattern are organically combined, so that the performances, such as road holding, abrasive resistance and wet sliding resistance of the tread, are guaranteed and the rolling resistance of the tire is reduced.

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...

AI Technical Summary

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
