摘要：

In order to develop eco-friendly water-repellent coating materials, UV-curable polyurethane acrylates containing hydrophobic fluorine group were synthesized. H12MDI with excellent yellowing resistance and water resistance was used as an isocyanate. Mixed polyols of polycarbonate diol and perfluoropolyether (PFPE) diol were used. 2-Hydroxyethyl acrylate with C=C bond was introduced for UV-curing coatings. Thermal and mechanical properties of the obtained UV-cured polyurethane acrylates were investigated. As increasing to PFPE content in polyol 10%, the contact angle of polyurethane acrylates increased from 75.9 to 107.1, tensile strength decreased but elongation increased due to the flexibility of PFPE. These results indicate that the surface hydrophobicity can be achieved by the introduction of PFPE in polyurethane acrylates.
