微波辅助聚(丙烯酸-丙烯酰胺)/沸石高吸水复合材料的制备及性能

利用微波辅助合成聚(丙烯酸-丙烯酰胺)/沸石高吸水复合材料,研究丙烯酰胺用量、引发剂、交联剂、中和度以及沸石的添加量等对吸水倍率的影响,利用红外光谱分析高吸水材料的官能团.结果表明:当沸石、丙烯酰胺、引发剂和交联剂量分别为丙烯酸单体质量的30%、40%、0.2%和0.04%,中和度为70%时,复合材料对自来水的吸附倍率达413 g/g,对生理盐水溶液的吸水倍率达95 g/g.

Microwave Assisted Preparation of Poly(acrylic acid-co-acrylamide)/Zeolite Superabsorbent Composite and Its Properties

The poly(acrylic acid-co-acrylaide) / zeolite superabsorbent composite was synthesized by microwave assisted method.The effects of the amount of acrylamide,initiator,crosslinker,degree of neutralization of acrylic acid,and zeolite concentration on water absorbency of superabsorbent composite were investigated.The characterization of functional groups of the super absorbent polymer were performed with Infrared spectrum.The optimum conditions are as follows: zeolite 30 %,acrylamide 40 %,initiator 0.2%,crosslinker 0.04 %,and neutralization degree 70 %.The prepared composite adsorption rates could reach 413 g/g for tap water and 95 g/g for NaCl saline solution.
