Abstract

The invention discloses itaconate/isoprene copolymer type biology base elastomer tread rubber and a preparation method thereof, belonging to the technical field of tires. Every 100 parts of itaconate/isoprene copolymer type biology base elastomer tread rubber can contain 5-40 weight parts of conjugated diene rubber and 60-120 parts of coordination fillers, the above fillers comprise more than 50 parts of silicon dioxide, 1-15 parts of silane coupling agent, 2-6 parts of zinc oxide, 1-3 parts of stearic acid, 1-4 parts of anti-aging agent, 1-4 parts of accelerant, 0-30 parts of fillers except silicon dioxide and 1-3 parts of sulfur. The biology base tire tread rubber is low in rolling obstruction, is proper in abrasion resistance and wet road holding property, and is a novel biology base elastomer 'green tire'.

Description

technical field [0001] The invention belongs to the technical field of tires, in particular to the formulation and processing technology of bio-based engineering elastomer tires based on renewable resources itaconic acid and biomass alcohol as main raw materials. Background technique [0002] The tire industry is a high-pollution and high-energy-consumption industry that relies on petrochemicals. With the massive consumption of non-renewable resources and the gradual improvement of people's awareness of environmental protection, making full use of biomass resources is of great significance to the sustainable development of the global economy and society. The development of biological Basic products are an important part of it. At present, most domestic tire tread rubbers are made of natural rubber, styrene-butadiene rubber, and butadiene rubber. Among them, natural rubber resources are scarce and the price is high, while other synthetic rubbers mainly come from petroleum-bas...
