摘要：以两倍蛭石阳离子交换容量的十六烷基三甲基溴化铵为插层剂,利用热液搅拌法、球磨法、煮沸法、熔融搅拌法4种不同的方法对蛭石进行插层处理。通过X射线粉晶衍射分析发现,十六烷基三甲基铵离子在蛭石层间具有倾斜双层、倾斜单层、双层平卧的排布模式。此外,随着处理方法中温度、机械力的由弱到强,十六烷基三甲基铵离子在蛭石层间的排布模式由多样向单一转变,插层层间距也有增大的趋势。
The vermiculites were intercalated by hexadecyltrimethylarnmonium bromide （HDTMA· Br） through stirring in hot water, ball milling, boiling and stirring in HAAKE mixer. The microstructures and properties of organic vermiculites were characterized by means of XRD. The results indicate that the configurations of HDTMA^＋ refer to paraffin type monolayer, paraffin type bilayer and lateral bilayer, and that the configuration types decrease while the values of interlayer spaces increase with the rising of temperature and intensifying of mechanical force in different intercalation means.
