摘要
为解决麻纺企业废料处理及环境污染问题,以麻纺企业废弃亚麻纱为原料,采用非均相聚合体系,以亚麻纤维素为基质接枝丙烯酸单体制备高吸水保水树脂。针对制备体系的工艺条件进行优化,并对制备的亚麻纤维素基高吸水保水树脂进行性能表征。结果表明,最优合成工艺为:丙烯酸单体、引发剂过硫酸铵、交联剂N,N'-亚甲基双丙烯酰胺相对纤维素的质量分数分别为500%、10%、4%,反应温度70℃,反应时间3 h;合成的高吸水保水树脂在去离子水、自来水和0.9%盐水中吸水倍率分别为658、382和65;在室温和不同温度干燥箱内均具备较优的保水效果。
In order to solve the problems of further treatment and environmental pollution caused by waste flax in the flax sector, waste flax yarns were grafted with acrylic acid monomers to synthesize a novel cellulose-based superabsorbent resin by heterogeneous polymerization process. The synthesis process was optimized and the resultant resin was characterized. The optimal synthesis conditions obtained were： the mass fractions of acrylic acid, initiator ammonium persulfate, N, N＇-methylene- acrylamide were 500% , 19% , 4% , respectively, on weight of cellulose, reacting at 70 ~C for 3 hours. The water absorbencies of the superabsorbent resin in deionized water, tap water and 0.9% NaCl aqueous solution were 658, 382 and 65, respectively. It also maintained excellent water retention capacity both at room temperature and in the oven with different temperatures.
