| 摘 要： | 用过硫酸钾(KPS)作引发剂,通过水溶液聚合法制得了淀粉/膨润土接枝衣康酸(IA)和丙烯酰胺(AM)高吸水性树脂(SBPIAAM)。研究了衣康酸与丙烯酰胺用量比、衣康酸中和度、交联剂用量以及引发剂用量等对吸液性能的影响。其最佳反应条件为:丙烯酰胺/衣康酸质量比为9.1∶0.9,衣康酸的中和度为70%,交联剂质量为单体质量的0.05%,作为引发剂的过硫酸钾的质量是单体质量的0.3%,反应温度为70℃,反应时间为6～10 h。

| Abstract: | Starch/bentonite grafted itaconic acid(IA)-acrylamide(AM) superabsorbent(SBPIAAM)is prepared by solution polymerization method with potassium persulfate as initiator.The influence of the ratio of itaconic acid and acrylamide,the neutralization degree of itaconic acid,the crosslinker and initiator dosage on the swelling performance of SBPIAAM is investigated.The optimum reaction condition is shown as follows:9.1∶0.9 of the ratio of acrylamide and itaconic acid by mass,70% of the neutralization degree of itaconic acid,0.05% of crosslinker and 0.3% initiator(ratio to the monomer by mass),70℃ of the temperature and 6-10 hours of the reaction time. |
