摘要/Abstract

摘要： 以高岭土为原料，选取50%水合肼作为插层剂，采用直接液相插层法，并辅以磁力搅拌，成功地将肼分子插入到高岭石结构层间，制得肼插层高岭土材料。利用红外光谱和粒度分析仪对产品进行了表征。IR谱表明, 插层中肼分子中的NH基与高岭石内表面羟基之间产生了N-H-OH作用，形成了新的氢键；插层反应后的样品，其粒径小于5 μm的颗粒占总颗粒数的比例降低了10.55%，平均粒径增大了46.84%。

关键词: 高岭土, 插层材料, 肼

Abstract: With natural mineral kaolinite as raw material, 50% hydration hydrazine as intercalation chemicals, the authors intercalated hydrazine molecules (NH₂-NH₂)between the layers of Kaolinite successfully by direct liquid intercalation,stirring at the same time,and prepared the hydrazine-kaolin intercalation complex material. The product was characterized by the infrared reflectance spectroscopy and the granularity analyse apparatus . The IR spectrum indicate, the new hydrogen bondings was formed in the N-H-OH interaction between the N-H in the hadrazine molecules from intercalation chemicals and the hydroxypyzidone(-OH) in the inner surface of kaolin. The average particle size of the products has increased by 46.84%,and the percent for the particles which radius is less than 5 micron has decreased 10.55%.

Key words: kaolin, intercalation complex, hydrazine
