摘要
采用正交设计的试验方法较全面地研究了壳聚糖(CS)和高岭土(KL)的添加,对丙烯酸(AA)/丙烯酰胺(AM)系列树脂在吸水和吸盐性能上的改善,并探讨了共聚合成高吸水树脂的合成条件,优化出最佳的工艺生产配比与反应条件,得出制备吸水率最佳的合成工艺条件是:0.7%引发剂,3%CS,90%中和度,70℃,30%的KL,10%AM和0.01%的交联剂,利用该优化的工艺合成的高吸水性树脂在去离子水中的吸水倍率为612 g/g。红外测试表明该合成树脂为四种原料单体的接枝共聚物,而重复吸水性能的测试也表明该四元共聚树脂有较好的重复利用能力。
The effect on the water and salt absorption performance of acrylic acid （AA）/acrylamide （AM） series resins with different content of chitosan and kaolin were studied synthetically by orthogonal experimental design. Finally, the optimized craft production ratio and reaction conditions is： 10% acrylamide, 0.7% initiator, 3% chitosan, 90% of neutralization degree, the temperature of 70 ℃, 30% kaolin and 0.01% cross-linking agent. It is shown that the water absorption rate can reach 607g/g. The FT-IR test show that the quater-nary copolymer resin was synthesized by the four monomer copolymer, and repeat the performance of water absorption tests also show that the quaternary copolymer resin has a good recycle ability .
