摘要
以丙烯酸和腐植酸为原料,N,N′-亚甲基双丙烯酰胺为交联剂,过硫酸钾为引发剂,合成具有保水抗旱功效、有利于植物生长的高吸水性树脂。考察了交联剂、引发剂、NaOH用量对吸水倍率的影响;利用红外光谱和扫描电镜对所得树脂进行了表征。对聚丙烯酸钠/腐植酸型高吸水性树脂进行了植物生长和节水效应的实验,结果表明,该吸水性树脂对植物生长有促进作用。
Sodium polyacrylate/humic acid,a super water-absorbent resins was synthesized.Effects of crosslinking agent,initiating agent and sodium hydroxide contents on water absorbency were investigated.Infrared spectra and SEM images of the superabsorbent were studied.Tests indicated the resin was not only helpful in water absorbing and saving but also helpful for plant growing.
