本文以玉米淀粉和海藻酸钠为原料、丙烯酸为反应单体、以过硫酸胺为引发剂、N,N′-亚甲基双丙烯酰胺为交联剂,采用水溶液聚合法,制备出吸水性能较好的淀粉-海藻酸系树脂,并进一步通过对海藻酸钠用量、反应引发剂用量和交联剂用量对淀粉-海藻酸系高吸水树脂吸水倍率的影响进行实验分析,得出最佳的合成工艺条件。
In this paper, corn starch and sodium alginate as raw materials, acrylic acid as the reaction monomer, ammonium persulfate as initiator, N, N’-methylene-bis-acrylamide as a cross-linking agent, aqueous solution polymerization, prepared water absorption Better starch-alginate resin, and further through the experimental analysis of the amount of sodium alginate, the amount of the reaction initiator and the amount of cross-linking agent on the water absorption capacity of starch-alginic acid superabsorbent resin obtained the best Synthetic process conditions.
