摘　　要：本文采用水溶液聚合法,以小麦秸秆(WS)和丙烯酸(AA)为原料,复配黄土(Loess),用N,N′-亚甲基双丙烯酰胺(MBA)作交联剂、过硫酸铵(APS)为引发剂,合成了小麦秸秆/聚丙烯酸/黄土(WS-g-PAA/Loess)复合型高吸水树脂。通过研究表明交联剂,引发剂和黄土添加量分别为0.155%、1.23%和7.7%时,合成的复合型高吸水树脂的吸水性能最佳,其对自来水和蒸馏水最大吸液倍率分别为120.0 g/g和440.0 g/g。In this paper,a composite superabsorbent resin(WS-g-PAA/Loess)from wheat straw(WS),acrylic acid(AA),and compound loess(Loess)was synthesized by aqueous solution polymerization,N,N′-methylene double acrylamide(MBA)acted as a cross-linker and ammonium persulfate(APS)as an initiator.The research shows that the addition amount of crosslinking agent,initiator and loess accounts for 0.155%,1.23%and 7.7%,the synthetic superabsorbent resin has the best water absorption performance,and the maximum absorption rate are 120.0 g/g and 440.0 g/g corresponding for tap water and distilled water.
