| 摘 要： | 以N, N-亚甲基双丙烯酰胺为交联剂, Iragure 184为光引发剂, 采用紫外光引发聚合的方法制备了高岭土/聚(丙烯酸-丙烯酰胺)高吸水性复合材料。研究了高岭土含量对复合树脂的吸水性、 吸水速率、 保水性及吸盐性等性能的影响, 并用红外吸收光谱(FTIR)、 X射线衍射(XRD)和扫描电镜(SEM)方法表征了复合材料的结构和形态。结果表明: 当高岭土的质量分数为15％时, 复合材料具有较好的性能, 其吸水倍率为1095g/g, 吸盐水倍率为94.7g/g, 吸水速率和保水性能明显改善。

| Abstract: | The superabsorbent composite of kaolinite/poly (acrylic acid-co-acrylamide) was prepared by UV photopolymerization using N, N-methylene-bis-acrylamide and Iragure 184 as crosslinker and photoinitiator respectively. The effects of the amount of kaolinite on water absorbency, water absorbing rate and water retention were studied. The structure and morphology of the composite were investigated through FTIR, XRD and SEM. The results show that the composite at 15% mass fraction of kaolinite exhibits excellent performance in the water absorbency of 1095 g/g, the salt water absorbency of 94.7g/g, quick absorbing rate and the better retention ability. |
