Embodiment

[0045] The formula composition of the rubber composition is listed in Table 1, and the preparation of the rubber compound is the same as that of the comparative example.

[0046] The main properties of the rubber compositions of Comparative Examples and Examples are listed in Tables 2-4.

[0047] As can be seen from the results of Table 3 and Table 4, the embodiment has reached a good balance in terms of rolling resistance, wet skid resistance and wear resistance. Compared with Comparative Example 1, the rolling resistance has reduced by 15.3%, and the wet skid resistance Slightly improved, wear resistance is largely unaffected. At the same time, the compression fatigue temperature rise of the rubber composition of the example is also small. The rolling resistance of Comparative Example 2 was only reduced by 5%, and the rolling resistance of Comparative Example 3 was greatly reduced, but the wear resistance was seriously affected.

Abstract

The invention discloses a rubber composition with a low rolling resistance. The rubber composition is prepared and formed by using modified butylbenzene nanopowder powder and at least one rubber containing unsaturated double bond, a reinforcing agent carbon black and other rubber accessory ingredients. Under the precondition of not reducing the processing property, the vulcanized rubber rolling resistance of the rubber composition is reduced by 15.3% and the wet-skidding resistance property is improved; and the rubber composition is especially used as the tread rubber of the tyre.

Description

technical field [0001] The invention relates to a styrene-butadiene rubber composition, more specifically to a composition composed of modified cross-linked powder rubber, styrene-butadiene rubber and the like and its vulcanized compound. Background technique [0002] With the increasingly stringent policies and regulations for carbon dioxide emission reduction and the increasing shortage of oil resources, how to reduce vehicle fuel consumption has become the focus of the automotive industry and users. Reducing the rolling resistance of tires is one of the important measures to reduce vehicle fuel consumption. [0003] In the research of reducing the rolling resistance of tire rubber (mainly tread rubber), the so-called "magic triangle" problem of contradictory rolling resistance, wet skid performance and wear resistance has been encountered. Simply increasing the amount of softener can improve the tire's wet skid resistance, but its wear resistance will decrease and rolling...
