中文摘要

以天然蒙脱土(MMT)和十六烷基三甲基溴化铵(CTAB)改性的有机蒙脱土(OMMT)为原料,用具有阻燃性质的三聚氰胺、双氰胺-甲醛树脂缩合物(MDFP)作为插层剂与蒙脱土层间的阳离子进行交换,优化反应条件(改性时间、温度及质量配比) ,制备出层间距不同的蒙脱土-氨基树脂纳米复合材料,用XRD、FT - IR对产物进行表征。结果表明, 三聚氰胺、双氰胺树脂缩合物已成功插层进入到两种蒙脱土层间。在50~70 ℃的水浴下加热,质量配料比小于10%,反应4 h的实验效果最好,有利于制备插层型或插层-剥离型蒙脱土-

英文摘要

Phosphorylated-amine resin compound (MDFP) was synthesized by melamine ,dicyanodiamide ,formaldehyde and phosphoric acid. It can be used as a intercalation agent to exchange the inorganic cations which were absorbed in the interlayers of the natural montmorillonite(MMT) and the OMMT modified by cetyltrimethylammonium bromide(CTAB). By optimizing reaction conditions ( reaction time, temperature and proportion of MMT), a series of montmorillonite clay amino resin nano composite materials with different interlayer space were prepared and identified by X ray diffraction and infrared spectra. The results show that the intercalation agent of amino resin intercalated into the layers of MMT。The optimal reaction conditions of preparing the nano composites were the mass ratio of MMT less than 10% under 50 ~70 ℃ for 4 hours. Leather application experiments indicate that the materials have good retanning and filling properties and functions of flame retardant.
