Abstract:

以丙烯酸(AA)、2-丙烯酰胺-2-甲基丙磺酸(AMPS)和甲基烯丙基聚氧乙烯醚(HPEG-2400)为单体,以过硫酸铵(APS)和亚硫酸氢钠为引发剂,N,N'-亚甲基双丙烯酰胺(NMBA)为交联剂,采用溶液聚合法制备了耐盐性能较好的高吸水性新型保水剂,并用FTIR对保水剂进行表征。研究了不同单体配比、交联剂用量、中和度及温度等因素对其保水性能的影响。实验结果表明当固定引发剂质量分数为1%,单体质量比为AAAMPSHPEG-2400=1034,交联剂质量分数为0.02%,中和度为60%,温度为60℃时,合成得到的保水剂在1%氯化钾溶液中的吸水能力达201g/g,对去离子水吸水能力达1787g/g。
