摘　　要：以腐植酸(HA)为有机质,丙烯酸为亲水改性单体,凹凸棒石(ATP)、高岭土(KL)无机矿质及过硫酸钾(KPS)为引发剂,N,N’-二亚甲基双丙烯酰胺(MBA)为交联剂,采用水溶液合成法制备具有网络结构的HA/AA/ATP和HA/AA/KL2种高吸水性树脂。研究了单体质量、中和度、引发剂质量、交联剂质量对2种高吸水树脂吸水和吸盐水性能的影响。对优化后的2种高吸水性树脂进行了结构及表面形貌表征,考察了吸水过程及其吸水(盐水)率、吸水(盐水)速率。HA/AA/ATP and HA/AA/KL,two kinds of ternary super absorbent polymers( SAP) both with a network structure,are prepared through aqueous solution synthesis using humic acid,acrylic acid,attapulgite,kaolin as raw materials,potassium persulfate as initiator,N,N’-dimethylenebisacrylamide as cross-linking agent. The effects of neutralization degree of acrylic acid,monomer ratio,dosage of initiator and dosage of cross-linking agent on the performance of two kinds of SAP for absorbing water and brine are investigated.The structure and surface morphology of these two SAPs are characterized,and the water absorption process,water( saline) absorption rate and water( saline)absorption speed are studied.
