反相悬浮聚合法制备腐殖酸高吸水性树脂进展

Progress in Humic Acid Super-absorbent Resin Prepared by Inverse-phase Suspension Polymerization

反相悬浮聚合法制备腐殖酸-聚丙烯酸高吸水性树脂(HA-PAA),论述了高吸水性树脂的结构及复合机理,阐明了高吸水性树脂的应用领域。腐植酸树脂具有良好的吸附、吸水、降滤失和抗温、抗盐性能,得到了广泛的应用。随着腐植酸树脂研究的进展,其应用前景将更加广阔。

A superabsorbent resin（HA-PAA） was prepared by reversed-phase suspension polymerization.The structure and combination mechanism of superabsorbent resin were described.The application fields of superabsorbent resin were described.Humic acid resins prepared by different methods show good adsorption,water absorbing,filtrate reducing,heat-resistant and salt resistant properties.Thus humic acid resins are employed to treat heavy metal waste water,to hold water and prevent drought,as well as additives in drilling.With the progress of research,the application of humic acid resin will be more promising.
