选用异佛尔酮二异氰酸酯（IPDI）、聚酯多元醇（PCDL）、二羟甲基丙酸（DMPA）、甲基丙烯
酸羟乙酯（HEMA）、季戊四醇三丙烯酸酯（PETA）、三乙胺（TEA）、甲基丙烯酸十二氟庚酯（DFHMA）为
主要原料合成了一种UV固化水性含氟聚氨酯。采用FT-IR、1H NMR、光学接触角测量仪、粒度分析
仪、热重分析仪、电子拉力机等对涂膜的结构与性能进行了表征与测试。结果表明:随着甲基丙烯酸
十二氟庚酯的加入，乳液粒径变大，分布变宽，涂膜接触角明显变大，吸水率明显降低，热稳定性有所
提升，拉伸强度变大。当甲基丙烯酸十二氟庚酯添加量为6%时，涂膜综合性能最好。
A side chain fluorinated UV curable waterborne polyurethane was synthesis
via radical polymerization of isophorone dissocyanate (IPDI), polycarbonate glycol (PCDL),dimethylolpropionic acid (DMPA), hydroxyethyl methylacrylate (HEMA), pentaerythritol triacrylate (PETA), triethylamine (TEA) and dodecafluoroheptyl methacrylate (DFHMA). The structure and properties of the cured film were characterized by Fourier-transform infrared(FT-IR)spectroscopy, 1H NMR, optical contact angle measuring instruments, particle size analyzer, thermal gravimetric analyzer and electronic tensile machine. The results indicated that with the addition of DFHMA increased, the emulsion particle size and its distribution,the contact angle, the thermal stability and tensile strength were obviously improved and the water absorption decreased. When the content of DFHMA was 6%, the cured film showed an optimal comprehensive performance.
