| Abstract: |
| The effects of silica with different structure on the properties of green tire tread compound [solution polystyrene-butadiene rubber（SSBR）/cis-butadiene rubber（BR） blend] were studied. The results showed that，the average particle size of silica 1165MP was the smallest，the reinforcing property was the best，and the wet slip resistance of the filled compound was the best. Silica WL180 was uniformity dispersed in the SBR/BR blend，and the rolling resistance of the filled compound was the lowest. The dispersion of silica VN3 in SBR/BR blends was the best. The average particle size of silica T383 was the largest，and the reinforcing property was the worst. The dispersion of silica DNS2 was poor，and Payne effect of the filled compound was the most obvious. |
