摘要

以糠醛渣纤维素为原料,丙烯酸(AA)和丙烯酰胺(AM)为复合单体,过硫酸钾(KPS)为引发剂,N,N-亚甲基双丙烯酰胺(MBA)为交联剂,采用反相悬浮接枝聚合法,制备了糠醛渣纤维素/AA/AM吸水树脂。通过傅里叶变换红外光谱仪和X-射线衍射仪对制备的吸水树脂进行了表征,探讨了复合单体用量、AA中和度、油水体积比、反应温度、KPS用量和MBA用量对吸水性能的影响。结果表明,当复合单体用量6.0g,AA中和度65%,KPS用量2.0g,MBA用量0.03g,反应温度60℃,油水体积比为1.4∶1,反应时间3h时,糠醛渣纤维素/AA/AM吸水树脂对去离子水、自来水和质量分数为0.9% NaCl水溶液的吸水(液)倍率分别为178.87、40.50和21.9g/g。

Abstract

The furfural residue cellulose-g-acrylic acid (AA) and acrylamide (AM) absorbent resin was prepared by reversed-phase suspension graft polymerization,which AA and AM were compound monomers,N,N-methylene bisacryl amide was used as crosslinked agent.The structure of the absorbent resin was characterized by fourier transform infrared spectroscopy and X-ray diffractometry.The effects of monomer amount,neutralization degree of acrylic acid,volume ratio of oil to water,reaction temperature,KPS amount and MBA amount on the water absorption were discussed.The results showed that when the monomer dosage was of 6.0g,neutralization degree of 65%,KPS dosage of 2.0g,MBA dosage of 0.03g,oil-water volume ratio of 1.4∶1,reaction temperature of 60℃ and the reaction time of 3h,the prepared absorbent resin had a absorbency (liquid) ratio of 178.87g·g-1,40.50g·g-1and 21.9g·g-1 to deionized water,tap water and 0.9% NaCl aqueous solution,respectively.
