摘　　要：利用反气相色谱法研究未经处理的高岭土和分别用硅烷偶联剂ＫＨ５６０、钛酸酯偶联剂ＮＤＺ－２０１处理后的高岭土的表面性质．同时用扫描电子显微镜研究表面处理对高岭土在尼龙６基体中分散行为的影响．结果表明，表面处理明显改变了高岭土的表面性质，从而影响到高岭土在尼龙６基体中的分散质量．The surface propertics of untrcated kaolin silanc coupling agent KH560 treated kaolin and titanic coupling agent NDZ-201 trcated kaolin and the effects of surface treatment on dispersion of kaolin in nylon 6 matrix were studied by means of inverse gas chromatography and scanning of electron microscopy,respectively. The results show that surface treatment apprently alters thermodynamic functions of absorption and and-base propcrties of kaolin surfaces,and affects qualities of dispersion of kaolin in nylon 6.
