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.
