Abstract:
      The effects of the particle size and structure of carbon black N110, N220, N234, N774, and DZ-13 on the static and dynamic mechanical properties of carbon black filled styrene butadiene rubber (SBR) composites were studied. The results showed that the SBR filled by carbon black with small primary particle size and high structure, such as N234, exhibits a high mechanical strength and wear resistance but has a high dynamic hysteresis due to the high value of tan ? at 60 ℃. Since N774 has the largest particle size and the lowest structure among the five types of carbon black, it filled SBR composite has the lowest rolling resistance and the highest wet skid resistance, while its mechanical strength and wear resistance are poor. For DZ-13, its primary particle size is slightly larger than that of N110, N220, and N234, which may lead to the decrease of the mechanical strength of its SBR composite. However, its high structure compensates this short coming and the SBR filled by DZ-13 exhibits a mechanical strength and wear resistance comparable to that of N110 and N220, and is only slightly lower than that of N234. In addition, its relatively high aggregate size makes its SBR composite has low rolling resistance and dynamic temperature rise.
