摘　　要：本论文以废弃木材纤维为原料,经粉碎、浸泡,氢氧化钠碱化、氯乙酸醚化处理,烘干后得到水溶性大大增强的羧甲基纤维素。然后以此为母体,以丙烯酸和丙烯酸钠为单体,以过硫酸钾为引发剂,以N,N’亚甲基双丙烯酰胺为交联剂,在高温下发生接枝聚合反应制备高吸水树脂。制备过程进行了单因素变量实验,在此基础上筛选条件进行了正交实验探究,得出最佳原料质量比为:羧甲基纤维素质量∶丙烯酸质量∶氢氧化钠质量∶交联剂质量∶引发剂的质量=1∶6∶2∶0.021∶0.042,其最大吸水率可达2535 g/g。实验证明本论文制备的高吸水树脂吸水率高,性能优良。In this paper,waste wood fiber was used as raw material.Through crushing,soaking,NaOH alkalization,chloroacetic acid etherification,drying,greatly enhanced water-soluble carboxymethyl cellulose was obtained.Then,at high temperature the superabsorbent polymer(SAP)was prepared by graft polymerization which was used acrylic acid and sodium acrylate as monomers,potassium persulfate as initiator and N,N’-methylene bis-acrylamide as crosslinking agent.The best raw material mass ratio is:carboxymethyl cellulose to acrylic acid to sodium hydroxide to crosslinking agent to initiator were1∶6∶2∶0.021∶0.042,and the maximum water absorption is 2535 g/g.The experimental results show that the SAP prepared in this paper has high water absorption rate and excellent performance.
