摘要
以有机小分子马来酸酐作为改性剂,利用球磨法在不同溶剂中对蛭石进行有机改性。对有机改性的蛭石进行了X射线粉晶衍射、Fourier变换红外光谱仪和热重分析表征。结果表明:在水溶液条件下,球磨能够使蛭石片层被马来酸酐分子剥离,蛭石的(001)面特征衍射峰消失。在有机溶剂中球磨,蛭石不能够被马来酸酐剥离。讨论了马来酸酐改性蛭石的机理。研究了球磨时间对马来酸酐改性蛭石的影响。
Vermiculite was modified by maleic anhydride through ball milling in different solvents. The microstructures and properties of modified vermiculite were characterized by X-ray diffraction, Fourier infrared spectroscopy and thermal gravimetric analysis. Results indicate the vermiculite layer can be exfoliated by maleic anhydride only in water, and the characteristic diffraction peak of vermiculite disappears. However, the vermiculite layer cannot be exfoliated by maleic anhydride in organic solvent. The mechanism of vermiculite modification by maleic anhydride is discussed. The influence of ball milling time on modified vermiculite was investigated.
