The Influence on the Physical and Mechanical Properties of the Tread by Preheating of Raw Rubber

This paper using synchronous rotor mixer, had researched the influence of preheating of raw rubber on the physical and mechanical properties of the tread under the same fill factor, rotor speed, cooling water temperature, and the pressure on top of bolt. According to processing and analysis of the experimental data, we can conclude that: As the temperature of raw rubber increased, the physical and mechanical properties of the tread had changed.
