Embodiment Construction

[0026] The following examples are given to further illustrate the present invention, and the claims of the present invention are not limited by the examples. The components of the rubber composition in the examples are all counted in parts by mass.

[0027] The rubber composition for tire tread rubber in the embodiment of the present invention comprises: a rubber component, white carbon black, a silane coupling agent, and an environment-friendly operating oil TDAE.

[0028] The rubber component is 100% raw rubber ternary integrated rubber (E-SIBR) by emulsion polymerization. The microstructure of the emulsion polymerization integrated rubber used in Example 1 is as follows: the combined styrene content is 25.8%; the combined 1,4-butadiene content is 46.6; the 1,2-butadiene content is 10.5%; The amount of 1,2-isoprene was 1.9%, the amount of 1,4-isoprene was 13.9%, and the amount of 3,4-isoprene was 1.3%.

[0029] The white carbon black may be precipitated white carbon black ...

Abstract

The invention discloses a rubber composition used in the production of semi-steel radial tire tread rubber, the rubber composition singlely uses emulsion polymerized ternary integrated rubber as a rubber crude rubber component, the prepared tire tread has good wet-skid resistance and low rolling resistance performance, the rubber composition uses operation oil in accordance with requirements of the EU (European Union) labeling regulations, and the composition is in accord with the requirements of green environmental protection. The production of the rubber composition saves time, and the energy consumption is lower. The rubber composition is particularly suitable for making the tire tread of the semi-steel radial tire used in winter.

Description

technical field [0001] The invention relates to a rubber composition for making tread rubber of semi-steel radial tires, and the rubber composition is especially suitable for making treads of semi-steel radial tires used in winter. The invention belongs to the technical field of rubber and tire industrial production. Background technique [0002] With the development of green and environment-friendly tires, and in order to meet the requirements of EU tire labeling regulations, the international rubber industry has adopted rubber compositions based on solution-polymerized styrene-butadiene rubber to make tread rubber for car radial tires, including all the use of solution-polymerized styrene-butadiene rubber. Styrene-butadiene rubber or solution-polymerized styrene-butadiene rubber and part of butadiene rubber. There are also manufacturers who use solution polymerization styrene-butadiene-isoprene rubber, that is, solution polymerization ternary integrated rubber. According...
