摘　　要：运用种子乳液聚合法制备了固含量(固体质量分数)为45%的含氟乳液;运用后乳化法制得了环氧乳液。ATR-FTIR测试表明环氧乳液与含氟乳液进行了有效的拼混。运用KrussK12型动态表面能分析仪测试了含氟涂膜对水和十六烷的接触角,对影响拼混乳液涂膜性能的因素如环氧树脂及其固化剂的比例、氟原子含量、成膜基材材质、成膜温度等进行了探讨研究。结果表明制备的含氟拼混乳液性能良好。The fluorinated latex with 45% of solids content was prepared by the seed emulsion polymerization and an epoxy latex was prepared by after-emulsion process.ATR-FTIR spectra indicated that the epoxy latex and fluorinated latex was mixed effectively.The contact angles of water and hexadecane were measured by Kruss K12 dynamic surface energy analyzer.The main factors such as ratio of epoxy resin and its curing agent,fluorine atom content,film formation substrates,film formation temperature influencing properties of latex films were studied.The results show the blend latex is a fluorinated latex of high performance.
