| 摘 要： | 以N,N-亚甲基双丙烯酰胺为交联剂,过硫酸钾为引发剂,采用水溶液聚合法制备淀粉接枝丙烯酸/沸石/粉煤灰高吸水性复合材料,研究了沸石与粉煤灰配比、淀粉添加量、交联剂用量、引发剂用量、中和度及反应温度对复合材料吸水率的影响。结果表明,粉煤灰与沸石在接枝聚合物中可较好的分散,复合材料对自来水的吸水倍率达314.4g/g,对供试生理盐水的吸水倍率达55.7g/g。

| Abstract: | With N,N-methylene bisacrylamide as crosslinking agent and potassium persulfate as initiator,the high-hydrophilia compound material starch-grafted acrylic acid/zeolite/fly ash was prepared by using aqueous solution polymerization method and the influence of proportion of zeolite to fly ash,addition amount of starch,doses of crosslinking agent and initiator,neutralization degree and reaction temperature on the water absorption rate of the compound material was researched. The results indicated that fly ash a... |
