摘　　要：以聚四氢呋喃二醇(PTMG)、异佛尔酮二异氰酸酯(IPDI)、二羟甲基丙酸(DMPA)为主要原料,季戊四醇三丙烯酸酯(PETA)为接枝剂,双酚A型环氧树脂E-44与甲基丙烯酸八氟戊酯(FA)为改性剂,制备了环氧树脂-含氟丙烯酸酯-水性聚氨酯杂化乳液(EWPUFA)。通过粒径、红外光谱(FT-IR)、拉伸强度、接触角、吸水率、X射线衍射(XRD)等分析和测试,考察了E-44用量对EWPUFA乳液及胶膜性能的影响。结果表明,E-44用量的增加提高了胶膜的拉伸强度,降低了胶膜的断裂伸长率、接触角、吸水率与结晶能力。A series of epoxy resin fluorinated acrylate waterborne polyurethane hybrid emulsions(EWPUFA)were synthesized using polytetramethylene glycol(PTMG),isophorone diisocyanate(IPDI)and dimethylol propionic acid(DMPA)as the main raw materials,pentaerythritol triacrylate(PETA)as the grafting agent,1H,1H,5H⁃octafluoropentyl methacrylate(FA)and bisphenol A⁃type epoxy resin(E⁃44)as the modifying agents.The effect of content of E44 on the properties of EWPUFA emulsion and film was characterized by particle size,FT⁃IR,mechanical property,contact angle,water absorption and X⁃ray diffraction(XRD).The test results showed that the addition of E⁃44 could improve the tensile strength of the film and reduce the elongation at break,contact angle,water absorption and crystallization of the film.
