摘要
对微波辐射下丙烯酸(AA)、丙烯酰胺(AM)和凹凸棒的水溶液聚合反应进行研究,合成凹凸棒复合P(AA-AM)高吸水树脂,探讨微波功率、辐射时间、单体配比、中和度、引发剂用量、交联剂用量等对高吸水性树脂吸液倍率的影响,并用红外光谱对产物的结构进行表征。合成的高吸水树脂吸水倍率达1580 g/g,在质量分数为0.9%的食盐水中的吸液倍率达170 g/g。
The aqueous solution polymerization of acrylic acid,acrylamide and attapulgite clay under microwave irradiation was studied,and a super absorbent resin was synthesized. The factors that influence on liquid absorbency rate of the super absorbent resin were discussed, including microwave power, reaction time, monomer ratio, neutralization degree of AA, initiator dosage,and crosslinking agent dosage. The structure of the super absorbent resin was characterized by the method of IR. It just needed 30 s to preparation the super absorbent resin. Its liquid absorbency rate was about 1 580 g/g and 170 g/g in purified water and 0.9 % NaCl solution.
