| 中文摘要: |
| 采用熔体插层法制备溴化丁基橡胶（BIIR）/有机蒙脱土（OMMT）纳米复合材料和三元乙丙橡胶（EPDM）/OMMT纳米复合材料，利用X射线衍射和透射电子显微镜研究其微观结构及OMMT分散状态在硫化过程中的变化。结果表明：橡胶/OMMT纳米复合材料的插层结构在整个硫化过程中不断变化，且正硫化以后插层结构仍会随着硫化反应时间延长而发生明显改变；未硫化BIIR/OMMT纳米复合材料的插层结构层间距大于未硫化EPDM/OMMT纳米复合材料，硫化EPDM/OMMT纳米复合材料的插层结构层间距大于硫化BIIR/OMMT纳米复合材料；随着硫化程度提高，BIIR/OMMT纳米复合材料中OMMT的分散性能逐渐降低。 |
| 英文摘要: |
| Brominated butyl rubber（BIIR）/organic montmorillonite（OMMT） nanocomposite and ethylene propylene diene monomer（EPDM）/OMMT nanocomposite were prepared by melt intercalation method，and the microstructure change of the nanocomposites and the change of OMMT dispersion state during the vulcanization process were investigated by using X-ray diffraction and transmission electron microscope. The results showed that the intercalation structure of rubber/OMMT nanocomposite changed constantly in the vulcanization process，even after the optimum cure stage. The interlayer spacing of the intercalated structure of unvulcanized BIIR/OMMT nanocomposite was larger than that of unvulcanized EPDM/OMMT nanocomposite. The interlayer spacing of the intercalated structure of vulcanized EPDM/ OMMT nanocomposite was larger than that of vulcanized BIIR/OMMT nanocomposite. With the increase of vulcanization degree，the dispersion of OMMT in BIIR/OMMT nanocomposite deteriorated gradually. |
