对聚丙烯酸/羧甲基壳聚糖/蒙脱土复合树脂的结构进行了红外光谱表征,并系统研究了引发剂、交联剂、蒙脱土的用量以及丙烯酸与羧甲基壳聚糖的投料比对复合树脂吸水率的影响。结果表明,当丙烯酸和壳聚糖质量比为10∶1,有机蒙脱土含量为2%,引发剂和交联剂用量分别为2.5%和0.16%时,所合成的聚丙烯酸/羧甲基壳聚糖/蒙脱土复合树脂吸(盐)水率最高,分别达到468倍与76倍。
The structure of polyacrylic acid / carboxymethyl chitosan / montmorillonite composite resin was characterized by FTIR spectroscopy, and the amount of initiator, cross-linking agent, montmorillonite and the ratio of acrylic acid and carboxymethyl chitosan Effect of Feed Ratio on Water Absorption of Composite. The results show that when the mass ratio of acrylic acid to chitosan is 10:1, the content of organic montmorillonite is 2%, the amount of initiator and cross-linking agent are 2.5% and 0.16% respectively, the synthesized polyacrylic acid / carboxymethyl Chitosan / montmorillonite composite resin absorption (salt) the highest water rates, respectively, 468 times and 76 times.
