摘要
采用不同结构的硅烷偶联剂(KH550、KH560、KH570)分别对超细蒙脱土进行接枝改性,并利用热失重分析(TGA)、X射线衍射分析(XRD)和扫描电子显微镜(SEM)对其结构性质进行表征,研究结果表明:经KH560接枝的细化蒙脱土层间距最大,其次为经KH550接枝的细化蒙脱土,而经KH570接枝的细化蒙脱土层间距最小。比较而言,经KH560接枝的细化蒙脱土颗粒表面分散片层最多,其次为经KH550接枝的细化蒙脱土,而经KH570接枝的细化蒙脱土表面分散片层最少。
The super-refined montmorillonite was grafted by silane coupling agent with different structure, respectively. The structure and properties were characterized by thermogravimetric （TG） analysis, X-ray diffraction （XRD） , and scanning electron micrographic （SEM）. The results showed that grafted super-refined montmorillonite with KH560 had the highest basal spacing, followed by grafted super-refined montmorillonite with KH550, and a minimum for grafted super-refined montmorillonite with KH570. Comparatively speaking, grafted super-refined montmorillonite with KH560 had the most dispersed layers, followed by grafted super-refined montmorillonite with KH550, and a minimum for grafted super-refined montmorillonite with KH570.
