Abstract Over the past few years, silicone-based polymers have been widely studied because silicone shows unique surface properties, such as hydrophobicity, film formability, etc and then silicone-based compounds are being mainly applied to the coating field. To have these characteristics in coatings, it is crucial that silicone component participates in covalent bonding. In this research, UV-curable polyurethane acrylates (PUAs) with different molecular weights and contents of reactive silicones were synthesized to improve the surface and mechanical properties of coating films. The synthesized PUAs were identified with FT-IR spectra and the mechanical properties of the cured PUAs films were investigated by UTM. The water contact angle of the cured PUAs was measured by the drop shape analyzer and the gloss values of PUAs were measured by a gloss meter. Finally, the optimum content of reactive silicones in the PUAs was obtained.

含反应性有机硅的紫外光固化聚氨酯丙烯酸酯的合成及性能

摘要 近年来，由于有机硅具有独特的表面性能，如疏水性、成膜性等，有机硅聚合物得到了广泛的研究，有机硅化合物主要应用于涂料领域。为了在涂料中具有这些特性，有机硅组分参与共价键合是至关重要的。在这项研究中，合成了具有不同分子量和反应性有机硅含量的紫外​​线固化聚氨酯丙烯酸酯 (PUA)，以改善涂膜的表面和机械性能。合成的PUA 用FT-IR 光谱进行鉴定，固化的PUA 薄膜的机械性能通过UTM 进行研究。固化的PUA的水接触角通过液滴形状分析仪测量并且PUA的光泽值通过光泽计测量。最后，得到了PUA中反应性有机硅的最佳含量。
