摘要
以过硫酸铵、亚硫酸氢钠作引发剂,N,N′-亚甲基双丙烯酰胺作交联剂,将木薯淀粉与丙烯酸、辣椒碱在水溶液中接枝共聚,合成了具有抗菌性的高吸水性树脂。考察了添加辣椒碱形式、反应温度、反应时间、丙烯酸中和度、引发剂和交联剂用量对产物吸水性能的影响,结果表明,添加辣椒碱提取母液,在70℃下反应2.5h,丙烯酸中和度85%,引发剂和交联剂用量分别为0.6%和0.04%时,合成的吸水树脂有较高的吸水倍率。
A novel antibiotic super- absorbent polymer was synthesized from cassava starch, acrylic acid, and capsaicin by graft copolymerization in aqueous solution using ammonium persulfate and sodium bisulfate as initiator and N, N＇-methylene biacrylamide as cross - linking agent. The effects of reaction conditions on water absorption of the product were investigated. The results showed that the product had good water absorption under the following conditions ： adding extraction of capsaicin, reaction temperature 70 ℃, reaction time 2.5 h, neutralization degree of acrylic acid 85% ,amount of initiator and cross - linking agent 0.6% and 0.04% respectively.
