摘　　要：通过FT-IR仪,对制备的高岭土/NR/SBR/BR复合材料进行了系统的分析和研究。结果表明:硅烷偶联剂与高岭石表面产生了化学键合;在复合材料的硫化过程中硫磺与橡胶大分子形成了C-Sx-C键;高岭土的加入能够影响C-Sx-C键的形成,其内羟基能与橡胶大分子反应;高岭土在偶联剂的作用下融入橡胶基体中,提升了硫化胶的力学性能;FT-IR可以研究高岭土补强NR/SBR/BR复合材料的机理。By FT-IR instrument, the paper systematically analyzed and researched the prepared kaolin/ NR/SBR/BR composite. The results showed that the function way between silane coupling agent and the surface of kaolinite was chemical bonding. The chemical bond of C-Sx-C was generated by sulfur and rubber molecular through the vulcanization of composite. The addition of kaolin could influence the formation of the chemical bond of C-Sx-C, the inner hydroxy of kaolinite reacted with the rubber molecular. Kaolin integrated into the rubber matrix through the role of silane coupling agent, then the mechanical properties of composite was improved. The FT-IR could research the reinforcement mechanism of NR/SBR/BR with kaolin.
