Low rolling resistance all steel radial tire tread rubber composition

Abstract

The invention relates to the technical field of tire rubber, and particularly relates to a low rolling resistance all steel radial tire tread rubber composition. The composition is characterized by further comprising, based on 100 parts by mass of a natural rubber component, in parts by mass, 0-10 parts of a plasticizer, 28-50 parts of carbon black, 0.1-0.5 part of an anti-scorching agent, 10-20 parts of white carbon, 5-10 parts of porous silicon bead filler, 2-3 parts of a silane coupling agent, 1-3 parts of sulfur, 3-5 parts of an anti-aging agent, 5-8 parts of an activating agent, 1-3 partsof a protective agent, and 1-3 parts of an accelerator. The porous silicon bead filler product is applied into the all steel tread formulation, and is directly added with other fillers in a masterbatch mixing stage, a formulation dispersion degree can be improved, and the use of the filler can retain an original process and reduce a mixing time; and the filler has a relatively low price, and hasa relatively high economic advantage while reducing rolling resistance and maintaining physical properties.

Description

technical field [0001] The invention relates to the technical field of tire rubber, in particular to a low rolling resistance all-steel radial tire tread rubber composition. Background technique [0002] As we all know, with the rapid discovery of the automobile industry, countries around the world have increasingly stringent requirements on automobile pollutant emissions. The Chinese government requires automobile emissions to reach the National VI standard within two years. Faced with severe environmental challenges, all automobile manufacturers are actively looking for solutions. Green tires have been the focus of research in recent years. Reducing tire fuel consumption can reduce pollutant emissions. In addition to relieving environmental pressure, it can also bring economic advantages to consumers. [0003] The energy consumption of tires mainly comes from the tension and compression force generated between the internal structure of the tire due to friction between the ...
