摘要：利用富含高岭石的铝质岩制备多孔的铝硅酸盐聚合物基体材料,将甲基丙烯酸甲酯单体浸入到基体材料中引发聚合反应,制备有机改性陶瓷材料,采用N₂吸附-脱附法对材料进行表征。结果表明:基体材料经过浸渍、固化后,孔容、比表面积和平均孔径明显减小,最可几孔径由50 nm左右缩小至20 nm左右;与铝硅酸盐聚合物相比,有机改性陶瓷具有更好的强度与韧性。

Abstract： Porous basis materials of aluminosilicate geopolymer were prepared using aluminous rock containing lots of kaolinite. Organically modified ceramics were prepared by introducing methyl methacrylate monomer into basis materials and initiating polymerization. The materials were analyzed by the method of nitrogen adsorption-desorption. The results show that the pore volume， area surface and average pore size of the basis materials decrease obviously. The most probable pore size decreases from about 50 nm to about 20 nm after impregnated and solidified. Comparing with the aluminosilicate geopolymer， the mechanical strength and toughness of the organically modified ceramics are better.
