| 摘 要： | 以丙烯酸接枝淀粉为基体,不饱和聚酯酰胺脲树脂为交联剂制备出一种可降解高吸水性树脂,该树脂不加任何光引发剂即可紫外光固化成膜。研究了树脂的吸水速率及交联剂的加入量、光固化时间对产品吸水率的影响。结果表明,该高吸水性树脂对不同溶液均具有较好的吸收能力,吸水速度较快,在蒸馏水、自来水、0.9%NaCl溶液、0.9%KCl溶液中的吸水率分别为905,3501,00,120 g/g;10 min内对蒸馏水的吸收倍率达200 g。该高吸水性树脂的降解从表面开始,逐渐向里面降解。

| Abstract: | A degradable superabsorbent resin was prepared by acrylic acid grafted starch with unsaturated polyester-urea amide as a cross-linking agent,a membrane was prepared by the resin,in the condition of UV-curing without adding any photo-initiator.The influence of absorbency rate of the resin,the dosage of cross-linking agent and the UV-curing time on the absorbency were discussed.The results showed that the product had good absorbency ability to different solutions,and the absorbency rate was the fast.Water abs... |
