| 摘 要： | 以膨胀蛭石(EVMT)、丙烯酸(AA)、丙烯酰胺(AM)为原料,通过水溶液聚合法制得了聚(丙烯酸-co-丙烯酰胺)/蛭石高吸水保水复合材料.研究了蛭石的添加量、丙烯酰胺用量、中和度、引发剂用量以及交联剂用量等对吸水率的影响.得到的最佳反应条件为:中和度为70%.丙烯酰胺、蛭石、引发荆和交联剂量分别为丙烯酸单体质量20%、12%、0.8%和0.12%.结果表明,蛭石加入量为12%时,复合材料的吸水和保水性能明显得到增强.

| Abstract: | A novel superabsorbent composite of poly(acrylic acid-co-acrylamide)/vermiculite was synthesized by using vermiculite,acrylic acid and acrylamide in aqueous solution.The effects of the amount of acrylamide,initiator,crosslinker,degree of neutralization of acrylic acid,and vermiculite concentration on water absorbency were investigated.The optimum reaction conditions were:neutralization degree,70%;acrylamide,20%;vermiculite,12%;initiator,0.8%;crosslinker,0.12%,respectively.The results show that the introduce... |
