摘要
高吸水树脂属于新型功能高分子材料 ,其应用广泛 .我国主要研究对象是淀粉接枝丙烯腈和丙烯酸盐系 ,聚乙烯醇 (PVA)系高吸水树脂只有少数单位进行过研制 .文章采用悬浮聚合法 ,以顺丁烯二酸酐为交联剂 ,添加来源广泛、价格非常低廉的高岭土 ,制得了聚乙烯醇高吸水性复合树脂 .该树脂的吸水倍率和吸盐水倍率分别为 2 5 6和 2 9倍 .通过实验 ,讨论交联剂用量、高岭土添加量、水解程度等因素对吸水性能的影响 .
The superabsorbent resin belongs to new functional high molecule material.It has extensive imply and develops quickly.The research object is stratch crossing with acrylonitrile and acrylate in my country.The superabsorbent PVA resin is researched and made by only little units. A PVA superabsorbent composite resin containing kaolin was synthesized by suspension polymerization using maleic anhydride as cross linking agent. The water absorbency and salt water absorbency of the resin are 256g.g -1 and 29g.g -1 respectively. By a series of experiments, the influence of the amount of crosslinking agent, kaolin and of hydrolysis degree on water absorbency of the PVA superabsorbent composite resin were investigated. The water absorbency ratio and keeping water of the resin are studied.
