Study on the Effect of the Temperature Rise of Rubber Compound on Tread Rubber Quality during Mixing Process

Abstract:

With the method of two-stage mixing, two different tread rubbers have been mixed in internal mixer under the different process conditions. After the experiments, test the temperature rise of rubber compound, mooney viscosity and carbon black disperisity. Study the effect of process condition change on the temperature rise of two kinds of rubber compounds and analyze the relationships between the rubber temperature rise and mooney viscosity, carbon black dispersity. The study finds that the temperature rise of rubber compound has a relationship with the rotor speed of internal mixer, rubber viscosity and filling factors, but when the temperature rise of rubber compound is steady, the carbon black dispersity of rubber compound also can be steady. After two-stage mixing, carbon black dispersity of rubber compounds have been improved obviously. These results also imply that rotor speed of internal mixer and filling factor are very important to carbon black dispersity of rubber compounds.
