蒙脱石矿物特性及开发利用前景

蒙脱石矿物是一类具有天然纳米结构的无机超高分子量硅酸盐聚合物。因其特殊的结构特性而具有独特的物化性能,享有“万能原料”的美名。对蒙脱石矿物表面改性,改变矿物表面的物化性能,如表面结构、电性、吸附性能和反应活性,大大拓宽蒙脱石矿物的应用范围。目前常用的蒙脱石改性方法有三种:活化法、无机/有机改性法和交联法。蒙脱石无机凝胶、生态型改性蒙脱石复合材料、分子自组装改型蒙脱石环境材料、复配蒙脱石医药辅料、大型隐蔽工程新型蒙脱石基防水材料等研究是未来几年蒙脱石的主要开发方向。

CHARACTERISTICS OF MONTMORILLONITE AND ITS APPLICATION PROSPECT

Being of natural nanostructure,montmorillonite is a kind of inorganic macromolecular silicate polymer.Having special physical-chemical properties,it is called 'Almighty material'.Now montmorillonite has been widely used by modifying it on its surface to improve physical-chemical properties such as surface structure,electric properties,adsorption performance,and activities of reaction.There are three methods for modification of montmorillonite,including activiation treatment,inorganic/organic treatment and cross-linking treatment.In future,the main development tendencies of montmorillonite are as follows:inorganic gels of montmorillonite,ecotype montmorillonite compound,montmorillonite environmental materials by self-assembled approach,compound montmorillonite medicine auxiliary,new waterproofing materials based on montmorillonite in large hidden engineering.
