摘　　要：研究SSBR相对分子质量和结构对白炭黑补强SSBR材料的界面和硫化胶性能的影响。结果表明,SSBR相对分子质量越大、分子链越长,结合橡胶含量越大;随结合橡胶含量增大,填料的网络化程度降低,填料分散均匀,填料与基体界面结合充分,硫化胶物理性能好;复合材料的耐磨性能与混炼胶中结合橡胶含量无直接对应关系,填料与基体界面结合充分则耐磨性能好。The influence of molecular weight and structure of SSBR on the interface and physical properties of silica/SSBR composite was investigated. The results showed that the content of bound rubber increased as the molecular weight and molecular chain length increased;when the bound rubber content increased, the filler-network was weakened, filler distribution was improved, interaction between filler and rubber was enhanced,and the physical properties of vulcanizate were improved;the abrasive resistance of composite didn＇t show direct relationship to the content of bound rubber,and the abrasive resistance was increased as the interaction between filler and rubber was enhanced.
