摘　　要：选用玉米秸秆作为原料,N,N′-亚甲基双丙烯酰胺(MBA)作为交联剂,丙烯酸(AA)、丙烯酰胺(AM)作为单体,采用水溶液聚合法,制备玉米秸秆基高吸水性树脂(SAR)。通过红外光谱(FTIR)和扫描电镜(SEM)对树脂进行表征,并研究了单体组成和交联剂用量对树脂吸水和保水性能的影响。结果表明:单体接枝于秸秆之上,树脂呈三维网状结构;随着单体中AM用量的增加,树脂各项性能先增强后减弱,AM质量分数为50%时吸水性能最佳;随着交联剂用量的增加,树脂吸水性能先增强后减弱,MBA质量分数为0.20%时性能最佳。The super absorbent resin(SAR)based corn straw was prepared by choosing corn straw as matrix,N,N′-methylene-bisacrylamide(MBA)as crosslinking agent,acroleic acid(AA)and acrylic amide(AM)as monomer by aqueous solution polymerization.With the help of fourier transform infrared spectrometer(FTIR)and scanning electron microscope(SEM)to characterize the resin,the influences of monomer ratio and crosslinking agent usage on the properties of the resin were also studied.The results show that monomer was grafted on the straw,and the resin formed into a three-dimensional network structure.The properties of the resin first increase,then decrease with the increase of AM content in the monomer composition,which are best when the mass fraction of AM is 50%.The properties of the resin increase,then decrease with the increase of crosslinking agent usage,which are the best when the usage of MBA is 0.20%.
