| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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 didnt show direct relationship to the content of bound rubber，and the abrasive resistance was increased as the interaction between filler and rubber was enhanced. |
