采用磨盘型力化学反应器制备PA 6、PP混合微粉并与SBS共混制备复合材料 ,用SEM、TEM研究不同温度下材料的相结构变化。结果表明 ,随PA、PP填充量增加 ,低温下 ,塑料相从均匀分散到聚集态形成。在高温下 ,塑料颗粒相熔融合并使其分散相结构发生变化直至形成链状连续相 The PA 6 and PP mixed powders were prepared by a disc-type force chemical reactor and blended with SBS to prepare the composites. The phase-structure changes of the materials at different temperatures were investigated by SEM and TEM. The results show that with the increase of PA and PP loading, the plastic phase disperses uniformly to the aggregation state at low temperature. At high temperatures, the plastic particles are melted and the dispersed phase structure is changed until a continuous chain is formed
