Abstract: In order to improve the dispersion degree of carbon black and other additives, reduce consumption of energy and the temperature of discharging rubber compound, our research has been focused on preparation of rubber compound with different rubber particle size at filling coefficient of 0.6 and 0.7 in the mixer. The power consumption, the temperature of discharging rubber compound and the dispersion of carbon black were characterized in this study. The mechanical properties of the rubber compound have also been tested. The results indicate that reducing the particle size of rubber can reduce the consumption of energy and the temperature of discharging rubber compound and improve the mechanical properties, which is very important in rubber industry

Abstract: The NR/SBR/oranoclay nancomposites were prepared by mechanical mixing method. The dispersion of the oranoclay in the rubber matrix was characterized by X-ray diffraction and scanning electron microscopy. And the effects of different filler and contents on the mechanical properties were investigated. The results showed that the particles of organoclay can be dispersed homogeneously in the rubber matrix. Compbination of carbon black and organoclay shows the synergistic effect which lead to high tensile strength. In addition, organoclay can decrease the Mooney viscosity which is useful for processing. The method is simple, which can be used industrially for use of organoclay in elastomer.
