摘　　要：试验研究几种起始层间距不同的有机粘土及制备方法对有机粘土/NBR纳米复合材料微观结构和物理性能的影响。结果表明:有机粘土/NBR纳米复合材料中有机粘土的层间距较其起始层间距增大;与熔体法相比,预膨胀法制备的有机粘土/NBR纳米复合材料的物理性能较好,复合材料中有机粘土的分散尺寸更小,分散相态更加细致、均匀。The effects of different initial layer spacing of organic clay and preparation method on the microstructure and physical properties of organic clay/NBR nanocomposites were investigated experimentally.The results showed that,the layer spacing of organic clay in the nanocomposite was larger than the initial layer spacing.Compared with the composites prepared by melt method,the physical properties of the nanocomposite prepared by pre-expansion method were better,the dispersion size of organic clay was smaller,and the dispersion phase was finer and more uniform.
