有机粘土/NBR纳米复合材料的微观结构与性能

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
