摘要

使用新的交联剂合成一种新型可自降解的高吸水性复合树脂.以过硫酸铵为引发剂，柱撑膨润土层间的多羟基聚合铝阳离子为交联剂，膨润土、丙烯酸和丙烯酰胺为主要原料，采用水溶液共聚法合成高吸水性复合树脂.采用XRD测试法研究了膨润土的柱撑效果;通过研究高吸水性复合树脂吸去离子水和0.9%NaCl溶液的倍数探讨了柱撑膨润土和引发剂的最佳用量;通过观察高吸水性复合树脂吸水凝胶的状态初步探讨了复合树脂凝胶的自降解情况.结果表明：多羟基聚合铝阳离子被引入膨润土的层间，柱撑效果很好;柱撑膨润土和引发剂的最佳用量分别为单体总质量的2.4%，0.34%;所制备的高吸水性复合树脂比其他的高吸水树脂的自降解性好，在65℃下25天就已完全降解.

Abstract

One new type of super absorbent composite resin that can be self-degraded was prepared by using a new crosslink reagent.It was prepared by water solution co- polymerization based on acrylamide

acrylic acid

ammonium persulfat

bentonite and pillared bentonite.Ammonium persulfat was the initiator and polyhydroxyl-Al cations which was in bentonite layers was the crosslink reagent. The pillared effect of bentonite was studied by X-ray diffraction analysis; the best dosage of pillared bentonite and initiator was studied by researching the absorption capability of distilled water and 0.9% salt solution

respectively.The self-degradation of composite resin was studied by observing the state of the composite resin gel.The pillared effect was very good.The polyhydroxyl-Al cations was introduced into the layer of bentonite.The best dosage of pillared Bentonite and initiator was 2.4% and 0.34% of total monomer quality

respectively.The self-degradation of this composite resin was better than that of other super absorbent rein

At 65 ℃ it was self-degraded completely in 25 days.
