摘要
用低分子量氯磺化聚乙烯(LMCSM)对纳米氮化硅粉体进行表面改性,并将其添加到氯磺化聚乙烯(CSM)中制备橡胶纳米复合材料。利用橡胶加工分析仪(RPA-8000),扫描电子显微镜(SEM)对其表征。结果表明:添加少量改性纳米氮化硅粉体对CSM基体起到一定的补强作用,能够有效地提高材料的动态力学性能,并且添加生胶重量分数1.0%的改性纳米氮化硅粉体在橡胶基体中的分散性最好。
Low molecular-mass CSM was used to modify silicon nitrde nanopartieles（Si3N4）. Modified nanoparticles were then added into CSM rubber matrix to prepare nano-Si3N4/CSM composites. Rubber-process-analyzer（RPA8000）and scanning electron microscope （SEM） was used to analyze it. The results indicated that addition of modified nano-Si3N4 had a reinforcing effect on promoting dynamic mechanical properties obviously and 1.0% amount of CSM showed the best dispersion in the CSM matrix.
