Abstract:
      In this study，the silica/solution polymerized styrene butadiene rubber（SSBR） composites were preparedby in-situ modification using three kinds of silane coupling agents（Si69，Si75，NXT），and the effects of the silane coupling agents on the rheological and mechanical properties of the composites were studied. The results showed that the silane coupling agent NXT was more effective than the coupling agents Si69 and Si75 in reducing the network degree of the silica fillers.Compared with the silica/SSBR composites modified by silane coupling agents Si69 and Si75，the shear storage modulus of the silica/SSBR composites modified by silane coupling agent NXT was lower，the Payne effect was weaker，the processability was better，the loss factor and activation energy were smaller，the temperature dependence of the tensile storage modulus was weaker，the hardness，tensile strength and elongation at break were equivalent，but the tear strength was higher，the dispersion of the silica was excellent，and the interaction between the silica and rubber was stronger.
