| 摘 要： | 以VAE醋酸乙烯酯(VAc)-乙烯共聚物]为种子乳液、聚乙烯醇(PVA)为保护胶体、叔碳酸乙烯酯(VoeVa10)为VAc的共聚单体、OP-10为乳化剂、己二酰肼(ADH)/双丙酮丙烯酰胺(DAAM)为交联体系和叔丁基过氧化氢/甲醛次硫酸钠为氧化还原型引发剂,采用种子乳液聚合法制备了VAc/VoeVa10/DAAM共聚乳液;然后在反应后期加入后交联剂(ADH),得到改性聚醋酸乙烯酯(PVAc)乳液。结果表明:当w(PVA1788+PVA1799)=3%、m(PVA1788)∶m(PVA1799)=1∶1、m(VoeVa10)∶m(VAc)=(10～15)∶100、w(氧化剂)=0.3%、w(VAE)=10%、w(OP-10)=2%、m(ADH)∶m(DAAM)=(0.5～1.5)∶1.0且w(DAAM)=2%时,相应乳液具有优异的耐水性和稳定性,并且其涂膜柔韧性和粘接性能俱佳。
