Abstract: Polyurethane-acrylate resin has been widely applied in industry for its execllent performance. This paper has described the development course of Uv-cured coatings since 1960 s, as well as the synthesis of Uv-cured polyurethane acrylate oligomer and recent development progress in the self-cleaning properties. The research progress of three novel Uv-curable coatings: waterborne PUA, powder PUA and modified PUA were reviewed. The deficiency and solution of novel Uv-curable PUA coatings were proposed, and the application and development trend of uv-curable coatings were prospected.

Key words: UV-curable, PUA oligomer, self-cleaning, novel coatings

摘要： 聚氨酯丙烯酸酯(PUA)树脂以其独特的性能,在工农业生产中有着广泛的应用前景。本文概述了紫外光固化涂料自20世纪60年代以来的发展历程,并就紫外光固化PUA低聚物的合成以及近年来国内外有关其表面自清洁性能取得的新成果进行了介绍。综述了3种新型涂料:水分散型、粉末型及改良型紫外光固化PUA涂料的研究进展。提出了新型紫外光固化PUA涂料目前还存在的不足以及解决方法,并对未来紫外光固化PUA涂料应用前景与发展趋势进行展望。
