| 摘 要： | 以黄胞胶(XG)、丙烯酸(AA)为主要原料,N,N′-亚甲基双丙烯酰胺(MBAA)为交联剂,过硫酸铵(APS)为引发剂,合成了XG接枝AA高吸水性树脂。通过单因素试验研究了单体配比、中和度、引发剂用量、交联剂用量、反应时间和反应温度等对该树脂吸水性能的影响,采用正交试验法优选出最佳制备工艺条件,并对接枝共聚物的结构进行了表征。结果表明:影响树脂吸水性能的主要因素是引发剂用量、单体配比和交联剂用量;最佳制备工艺条件为m(AA)∶m(XG)=6∶1,AA中和度为60%,w(交联剂)=0.4%和w(引发剂)=1.0%(均相对于XG而言),反应温度为60℃;在此工艺条件下制取的树脂,其最大吸水倍率为904g/g;接枝共聚物在1630cm-1处出现C=O特征吸收峰,说明AA已成功接枝在XG链上。

| Abstract: | With xanthan gum(XG) and acrylic acid(AA) as main materials, MBAA as cross linker and APS as initiator, a superabsorbent polymer based on XG grafted by AA(XG-g-AA) was synthesized. The influences of some factors such as monomer ratio, neutralization degree, initiator and cross linker contents, reaction time and reaction temperature on water absorption of the copolymer were investigated by single factor experiments. The optimum synthesis condition of XG-g-AA was preferred by orthogonal experiments, and the s... |
