| 摘 要： | 以废报纸为原料,经脱墨、碱煮、酸煮可得纤维素,以N,N-亚甲基双丙烯酰胺为交联剂,过二硫酸钾为引发剂,与丙烯酸接枝共聚制备了吸水树脂。讨论了原料单体配比、交联剂用量等因素对吸水树脂性能的影响,考查了制得的吸水树脂对蒸馏水、自来水和一定浓度NaCl溶液的吸收性能。在最佳条件下制得的吸水树脂对蒸馏水的吸水倍率为340 g/g,对自来水的吸水倍率为280 g/g,对0.05 mol/L NaCl溶液的吸水倍率达50 g/g。

| Abstract: | Taking waste paper as raw material,by deinking,acid boiling,and acrylic acid,we get cellulose N,N-methylene bisacrylamide as crosslinker,potassium persulfate as the initiator,together with acrylic,we get water absorbent resin.This paper discusses the raw material monomer ratio,crosslinker content on the absorbent properties,investigated by the water absorbing resin obtained in distilled water,tap water and a certain concentration of NaCl solution absorption.In the best condition,the water absorbing resin di... |
