| Abstract: |
| The interaction between environmental friendly SSBR/BR blend and silica and its effect on compound properties were investigated. The results showed that with increase of the addition level of BR，the Payne effect of SSBR/BR blends was strengthened，and the dispersion of silica decreased，the crosslink density and vulcanization rate increased，and the elongation at break，tear strength，rebound value and wear resistance were overall improved，but wet skid resistance was reduced. Compared with SSBR2564S/BR blend，silane modified SSBR72612S/BR blend had stronger interaction with silica，and the dispersion of silica was better. Adding BR could reduce the Mooney viscosity of SSBR72612S，improve the physical properties and wear resistance of SSBR72612S/BR blend，and reduce rolling resistance． |
