摘要:
丙烯酸系高吸水树脂防潮性能差,影响树脂的贮存和使用,通过分步合成和复合交联剂两种方法制备出具有防潮性能的树脂,并测定了树脂的吸水倍率和吸湿倍率. 实验结果表明:采用分步合成法,当二次合成中引发剂和交联剂的用量(相对于一次粒子质量)分别为0.6% 和0.15%时,树脂的吸水倍率和吸湿倍率分别为974 g/g和14.8 g/g;采用复合交联剂法,当甲基丙烯酸β-羟乙酯的用量为N,N’-亚甲基双丙烯酰胺用量的50%~60%时,树脂的吸水倍率和吸湿倍率分别为912 g/g和14.8 g/g. 两种方法制备的树脂均具有一定的防潮性能,较普通丙烯酸系高吸水树脂吸湿倍率下降了25%.
Abstract:
The performance of moisture resistance of acrylic acid superabsorbent resin is poor, which influences the storage and use of resins. The water absorption resin with high moisture resistance was prepared by the secondary composition and the composite cross linker,then the moisture absorption rate and the hygrocopic rate of the resin were investigated. The experimental results show that the moisture absorption rate and the hygrocopic rate are 974 g/g and 14.8 g/g by using secondary composition method when the dosage of initiator and crosslinking agent(relative to the quality of a particle) is 0.6% and 0.15%; the moisture absorption rate and hygrocopic rate are 912 g/g and 14.8 g/g by using composite cross linker when the dosage of 2?蛳Hydroxyethyl methycrylate is 50%-60% of the N,N'?蛳methylene double acrylamide; the resin prepared by the two methods has good moisture resistance performance, and the moisture absorption rate of it decreased by 25% compared with the ordinary high absorbent resin.
