摘　　要：采用十六烷基三甲基溴化铵(CTAB)和十八烷基三甲基溴化铵(STAB)分别对无机粘土进行有机改性,然后制备有机粘土/SBR纳米复合材料,研究不同季铵盐类改性剂对无机粘土的改性效果。结果表明:CTAB改性有机粘土与STAB改性有机粘土的片层间距分别从无机粘土的1.26nm增加到3.77nm和4.39nm;CTAB改性有机粘土的片层结构较稳定,而且在橡胶基体中的分散效果较好;所制备的有机粘土/SBR纳米复合材料的片层结构较多,力学性能较好。Using cetyl trimethyl ammonium bromide（CTAB）and octadecyl trimethyl ammonium bromide（STAB） modified inorganic clay, the organic clay/SBR nanocomposites were prepared, the modification effect of different quaternary ammonium salts for the inorganic clay was studied. The results showed that, the slice layer spacing of the organic clay that was modified by CTAB and STAB increased to 3.77 nm and 4. 39 nm respectively from 1.26 nm. The layers of organic clay modified CTAB are more stable structure,and the dispersion in the rubber matrix is better;the organic clay/SBR nano- composites have obtained so more lamellar structure,and its mechanical properties are better.
