Problems solved by technology

However, silica itself has a strong cohesion, it is difficult to disperse evenly into the rubber compound, it takes a long time to mix with rubber, consumes a lot of energy, and the price of silica is relatively high. These factors are not conducive to the production of tire companies and the requirements of environmental protection.

Abstract

The invention discloses a full-terrain tire tread rubber reinforced and filled with diatomite and a preparation method of the tread rubber, and belongs to the technical field of tire manufacturing. The tread rubber comprises the following raw materials in parts by weight: 20-50 parts of 20# standard rubber, 40-70 parts of styrene-butadiene rubber 1502, 10-15 parts of cis-polybutadiene rubber 9000,20-40 parts of diatomite, 30-50 parts of precipitated white carbon black, 2-2.5 parts of sulfur, 4-5 parts of zinc oxide, 3-4 parts of stearic acid, 1.2-1.5 parts of an accelerator, 2-3 parts of an anti-aging agent, 10-12 parts of engine oil, 1-2 parts of a coupling agent and 1-3 parts of glycerol. The tire tread rubber provided by the invention has the characteristics of low Mooney viscosity, easy processing, short vulcanization time, excellent physical mechanical property, no pollution and the like, the production efficiency is improved, the production energy consumption is reduced, and thedevelopment requirements of energy-saving, low-carbon and environment-friendly green tire.

Description

technical field [0001] The invention relates to an all-terrain tire tread rubber filled with diatomite reinforcement and a preparation method thereof, belonging to the technical field of tire manufacturing. Background technique [0002] All-terrain tires are widely used tires with both off-road and road performance. At present, the filling and reinforcing agents of such tires in my country are mainly carbon black and white carbon black. With the continuous enhancement of people's environmental protection awareness and the development of the tire industry, green Tires have become the trend and direction of tire development in the world, and the development of all-terrain green tires has become a top priority for tire companies. [0003] As a tire reinforcing agent, silica can reduce rolling resistance, and has become an important reinforcing agent in the tire industry, and has been vigorously promoted and applied. However, silica itself has a strong cohesion, it is difficult ...
