【摘要】 以高岭土为原料,选取水合肼为插层剂,成功制备出片层厚度<20nm的高岭土。采用硬脂酸对高岭土进行表面改性,增强了高岭土与聚合物基体的相容性、界面结合力,并制备了高岭土/丁苯橡胶纳米复合材料。研究了高岭土不同片层厚度、不同填充量对高岭土/丁苯橡胶复合材料力学性能的影响,确定了高岭土的最佳填充量为40%。更多还原

【Abstract】 With natural mineral kaolinite as raw material,hydration hydrazine as intercalation chemicals,the kaolin powder whose thickness of lamina was less than 20nm was successfully prepared . The surface of kaolin was modifi ed by stearic acid in order to adding consistency and interface cohesion of kaolin and polymeric matrix,and kaolin/SBR nanocomposite. The thickness of lamina and using level of kaolin can affect mechnical properties of the nanocomposite. It is showed that the optimum using level of kaolin was 40% .更多还原
