| 摘 要： | 以淀粉、丙烯酰胺、丙烯酸为共聚单体,硝酸铝为交联剂,过硫酸钾为引发剂,Span-60/Tween-60为复合乳化剂,采用反相悬浮聚合法合成了一种新型暂堵剂淀粉-丙烯酰胺-丙烯酸共聚物,并采用SEM和FTIR技术对共聚物进行了表面形貌分析和结构表征;考察了硝酸铝用量、丙烯酸中和度和淀粉用量对暂堵剂吸水性能的影响。实验结果表明,暂堵剂的最佳合成条件:丙烯酰胺5.00 g、环己烷60 mL、0.80 g Span-60、0.40 g Tween-60、丙烯酸中和度80%、淀粉1.50 g、硝酸铝0.02 g、70℃、3 h;在该条件下合成的暂堵剂的吸水倍率最大,且具有适中的强度。
