摘　　要：采用溶液插层法制备了顺丁橡胶/有机蒙脱土(BR/OMMT)纳米复合材料,并对复合材料的微观结构和性能进行了研究。结果显示,BR大分子链插入到OMMT片层中,OMMT在橡胶中为纳米级分散;BR/OMMT纳米复合材料的力学性能和耐热性能较纯BR有很大的提高,BR/OMMT纳米复合材料具有优异的物理性能;OMMT对复合材料的门尼黏度影响很小,BR/OMMT复合材料的吃粉速度快,加工性能优异。The BR/OMMT nanocomposites were prepared by solution intercalation method and the microstructure and properties were studied. The TEM observation indicated the molecular chain of BR was intercalated into the OMMT layers, and OMMT was dispersed in BR on nano-scale. The mechanical properties of BR/OMMT nanocomposites improved greatly and heat-oxidative ageing properties was excellent when compared to pure BR. OMMT had little effect on Mooney viscosity of BR/OMMT nanocompsoites, the processing property of BR/OMMT nanocomposites was better with easy blending.
