Abstract: A novel water retention agent with high salt tolerance was prepared by graft copolymerization Acrylicacid (AA), 2-acrylamido-2-methylpropane sulfonic acid (AMPS) and methyl allyl polyethenoxy ether (HPEG-2400) were used as monomers, Ammonium persulphate (APS) together with sodium bisulfite were used as the initiator, while N,N’-methylenebisacrylamide (NMBA) were used as cross-linking agent. The molecular structure characteristics of the product was confirmed by Fourier transform infrared spectroscopy (FTIR). The factors, which can influence the absorbency of water retention agent, were investigated, such as weight ratio of monomers, the amount of cross-linker, the neutralization degree of AA and temperature. The results show that the water retention agent has the water absorbency of 1787g/g, and 201g/g KCl solution when initiator ratio is 1%, the neutralization degree of AA is 60%, the ratio of monomers is AA:AMPS:HPEG-2400=10:3:4, and the amount of cross-linking agent is 0.02% at 60℃.

Key words: water retention agent, anti-salt, water absorbency

摘要: 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AA:AMPS:HPEG-2400=10:3:4, 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。
