Study on the combination mechanism and production process of
activated silica powder and carbon black

Zhang Linfeng, Sun Yaguang

Abstract: Both carbon black and silicon powder are inorganic fillers of rubber. Carbon black has the main
reinforcing function to enhance the wear resistance and service life of rubber tire. Silicon powder has the
main stretching function to improve the elongation of rubber, reduce deformation and heat generation, and
reduce the rolling resistance of rubber tire. However, due to the fact that there are many active functional
groups in the molecular of silicon powder, there are many interactions among the groups in the molecular
when it is directly added into the rubber, resulting in the uneven dispersion of silicon powder in the rubber,
forming large particle and block distribution, and damaging the properties of the rubber. Therefore, in this
research, the two inorganic materials were chemically combined to give the advantages of silica powder
to carbon black to form a new type of dual phase carbon black, which broke through the "devil's triangle"
of tire, improved the physical and mechanical properties of compound, reduced the lag of compound,
reduced the rolling resistance of tire without losing the wet skid resistance.
Key words: carbon black; silicon powder; fluidizer
