Summary:以粘胶纤维生产过程中产生的半纤维素废碱液为主要原料,丙烯酸(AA)为接枝单体,N,N’-亚甲基双丙烯酰胺(NMBA)为交联单体,(NH4)2S2O8-NaHSO3为氧化还原引发体系,利用超声辐射技术合成半纤维素-丙烯酸接枝共聚高吸水树脂,并对其合成条件、结构及吸液能力进行了探讨。结果表明:在优化条件下合成的树脂吸蒸馏水率为311g/g,吸自来水率为102g/g,吸生理盐水率为55g/g,吸入工尿液率为31g/g,具有优良的吸水速率和保水能力。红外光谱及扫描电镜分析结果表明合成了具有蜂窝状网络结构的高吸水树脂。该树脂的成功合成,意味着半纤维素废碱液有望得以高效利用,变废为宝,为高吸水树脂的合成提供一种新的原料。
Bibliography:The hemicellulose super water absorbent resin is prepared by using ultrasonic irradiation technology,with the waste liquid produced during the preparation of viscose fiber which contains a large amount of hemicellulose as raw material,acrylic acid as graft monomer,N,N'-methylene bis acrylamide(NMBA)as cross linking agent,and(NH4)2S2O8-NaHSO3 as the redox initiation system.The synthesis conditions,structure and water absorption ability of resin are discussed.The results indicate that water absorbency of the resin is 311g/g,the tap water absorbency is 102g/g,the normal saline absorbency is55g/g,and the artificial urine absorbency is 31g/g under the optimal synthesis conditions,so the resin has great water absorption rate and water retaining capacity.The FT-IR and SEM analysis shows that the resin with honeycomb network structure is prepared.The successfully synthesized of the resin means that the hemicellulose waste liquid can be highly effectivelyrecycled,and it provides a kind of new raw material for the synt
