Investigation of the elastic and hysteresis properties of tread rubber tires with silica

The influence of different types silica, differing in quality characteristics, on the complex modulus rubbers, their elastic modulus, loss and also tangent angle mechanical are investigated. Mineral fillers silica 1 2 introduced at a dosage 80.00 phr into filled elastomeric compositions based combination synthetic styrene-butadiene polybutadiene used for manufacture treads passenger tires. tests carried out dynamic analyzer by cyclic compression vulcanizates temperature range 20–70°С. It is established that with characterized 8–56% lower value modulus. revealed rubbers containing 2, depending temperature, have 13–36% values 19–46% comparison samples 2. determined from 20 to 70°C 7–12% loss. As result study, it most expedient introduce mineral filler formulation tread rubber compounds This will make possible obtain increased elasticity adhesion road surface, as well heat losses environment fuel consumption.
