| 摘 要： | 以海藻酸钠和丙烯酸为原料,采用微波辐射法接枝共聚制备了聚丙烯酸(AA)-海藻酸钠(SA)高吸水树脂。探讨了交联剂及引发剂的用量、单体配比、丙烯酸中和度、微波功率等因素对树脂吸水倍率的影响规律,并进行了树脂吸水速率和保水性能的研究,用红外光谱对树脂结构进行表征。实验结果表明,该树脂在蒸馏水中的吸水倍率为733.92 g/g,在生理盐水中的吸水倍率为120.68 g/g,并且具有较快的吸水速率及良好的保水性能。

| Abstract: | Using sodium alginate and acrylic acid as row material,Polyacrylic acid-alginate superabsorbent resin was synthesized with microwave polymerization.The impact of factors on water absorption of rensin,such as the amount of crosslinking agent and initiator,the ratio of monomers,neutralization degree of acrylic acid,the power and time of microwave and so on,were discussed.The results showed that water absorption was733.92 g/g in distelled water and 120.68 g/g in nomal saline.The resin has a high water-absorption rate and good water retention properties. |
