A kind of low rolling resistance tire tread compound

Abstract

The invention relates to tire tread mix with low rolling resistance. The tire tread mix with low rolling resistance has the advantages that carbon black serving as a tread filler of a conventional tire is partially substituted by white carbon black, meanwhile, a right amount of silane coupling agent is added for chemically modifying the white carbon black, so that the Payne effect and loss angle tangent tan delta at a high temperature of the mix can be effectively reduced, further the rolling resistance of a tire is improved, the effects of reduction of oil consumption and exhaust emission and environmental friendliness are achieved, and therefore, by adopting the tire tread mix with low rolling resistance, about 50% of tread lag performance and about 20% of rolling resistance of the tire can be reduced, thus more than 30% of fuel is saved. The tire tread mix with low rolling resistance comprises the following comments in parts by weight according to a formula: 70-90 parts of natural rubber, 10-30 parts of cis-butadiene rubber, 5-30 parts of carbon black, 30-50 parts of white carbon black, 5-10 parts of coupling agent, 3-5 parts of zinc oxide, 1-3 parts of stearic acid, 3-6 parts of antiager, 1-2 parts of sulfur, 1.0-2.0 parts of promoter and 0.1-0.3 part of scortch retarder CTP.

Description

technical field [0001] The invention relates to a tire tread rubber material with low rolling resistance, which belongs to the field of rubber tire manufacturing. Background technique [0002] Green tires are the strategic direction for the development of the global tire industry. Many countries have put forward higher requirements for tire performance, and more and more countries are brewing or have implemented tire labeling regulations. For example, Japan has implemented a voluntary tire labeling system since 2010, the United States has passed regulations including tire labeling regulations as early as six years ago, and the European Union and South Korea will implement mandatory tire labeling regulations from November 1 this year. The global market share of green tires will increase by more than 15%. [0003] To reduce tire rolling resistance from the perspective of formula, it is necessary to optimize rubber types and reinforcing agents. The tread rubber of all-steel t...

Problems solved by technology

Currently using furnace carbon black, such as N234, N115, etc., although the wear resistance meets the requirements, but the heat generation is high, which cannot meet the requirements of low rolling resistance tires
