采用水溶液聚合法将丙烯酰氧乙基三甲基化铵(DAC)、丙烯酰胺(AM)、丙烯酸(AA)3种单体接枝到纤维素骨架中合成玉米秸秆基两性高吸水性树脂.研究单体用量、秸秆用量、交联剂用量、引发剂用量、反应温度、反应时间和中和度对高吸水性树脂吸液率的影响.通过扫描电镜图、红外光谱图对其形貌进行表征.实验结果表明,在秸秆、AA、AM、DAC的质量分别为1、5、1和0.5g,引发剂用量占单体比率为1.2％,交联剂用量占单体总量比率为0.1％,中和度为75％,反应时间为3h,反应温度为60℃的合成条件下,制备的高吸水性树脂(SAR)吸液率达最大,其吸水率为235.9g/g,0.9％NaCl溶液的吸收率为31.3g/g.
