摘　　要：用十六烷基三甲基溴化铵(CTMAB)对钠基蒙脱土进行有机改性,制得有机蒙脱土,采用水溶液聚合法将有机蒙脱土与衣康酸(IA)、N-羟甲基丙烯酰胺(N-MAM)共聚制备了有机蒙脱土复合型高吸水性树脂,研究了该树脂的吸液性能和热稳定性能.结果表明:当有机蒙脱土质量占聚合单体总质量3%时,复合型高吸水性树脂的吸水性、耐盐性和热稳定性得到了提高,在pH7～10范围吸水能力最强.Organic bentonite was prepared by modifying Na-bentonite withcetyl trimethyl ammonium bromide (CTMAB).A superabsorbent resinwas synthesized by aqueous polymerization of organic bentonite, itaconic acid (IA) and N-methylol acrylamide (N-MAM).The water absorbency and the thermal stability of the resin were investigated.The results showed that the water absorbency and salt tolerance increased in the pH range of 7~10 and the content of organic bentonite at 3%.TGA results indicated that the thermal stability of the resin was also improved.
