| 摘 要： | 选择实验室自制有机蒙脱土(OMMT),采用机械共混法制备了溴化丁基橡胶/三元乙丙橡胶/OMMT(BIIR/EPDM/OMMT)纳米复合材料。利用X射线衍射分析(XRD)和扫描电子显微镜分析(SEM)考察了复合材料的亚微观结构,表明成功制备出了BIIR/EPDM/OMMT纳米复合材料;不同OMMT含量的复合材料的力学性能测试结果表明:当OMMT用量为5份时,拉伸强度和撕裂强度分别提高了44%和43%;另外对纳米复合材料的硫化特性及表观交联密度进行了对比分析。

| Abstract: | BIIR/EPDM/OMMT nanocomposites were prepared by mechanical blending.X-ray diffraction（XRD）and scanning electron microscope（SEM）were utilized to assess the clay morphology.XRD and SEM results revealed that BIIR/EPDM/OMMT nanocomposites were successfully prepared.The mechanical properties of BIIR/EPDM/OMMT nanocomposites were studied through tensile and tear testing.The strength of nanocomposites improved significantly in the presence of OMMT.Comparing to pure BIIR/EPDM,when the content of OMMT was 5 phr in the nanocomposites,the tensile and tear strength can be improved by 44% and 43%,respectively.In addition,Vulcanized characteristic and apparent crosslinking densities were also discussed in this article. |
