| 摘 要： | 采用微波辐射合成方法,以龙须菜为原料,丙烯酸（AA）和丙烯酰胺（AM）为接枝单体,N,N′-亚甲基双丙烯酰胺（MBA）为交联剂,过硫酸钾为引发剂合成超强吸水剂LSAP,探讨制备吸水剂的最佳工艺条件,并对产物的结构、吸液速率、保水性能进行研究。结果表明,龙须菜吸水剂的最佳制备工艺为：单体/龙须菜质量比为2∶1,引发剂和交联剂的质量分别为单体质量的0.4%和0.06%,微波功率为500W时,合成的LSAP吸去离子水、吸生理盐水和尿液分别为1102、104、86.1g/g,此外产物具有较快的吸水速率和较好的保水能力。

| Abstract: | To prepare a kind of superabsorbent polymers by gracilaria lemaneiformis,superabsorbent polymer was synthesized by means of microwave irradiation. Acrylic acid and acrylamide were grafted onto gracilaria lemaneiformis by using potassium persulfate as an initiator in the presence of N,N'-methylenebisacrylamide (MBA) as a crosslinker. The univariate analysis was visually analyzed to choose the optimal conditions. The structure of LSAP was confirmed while the absorbing properties,swelling rate and water retent... |
