Abstract In this study, we synthesized a self-photocurable intermediate by Michael addition reaction and synthesized a polyurethane acrylate oligomer. Photo-curable coatings were prepared by mixing the synthesized oligomer and HDDA/TMPEOTA ratio with a reactive diluent. The films were coated onto glass plates and base treatment metal plates using bar coaters with thicknesses of 120 μm and 30 μm, respectively. The mechanical properties increased with increasing crosslink density. The pencil hardness test was the best when the TMPEOTA content was 6 or 8 wt%, and the adhesion and banding test showed excellent physical properties when the TMPEOTA content was less than 10 wt%. MEK rubbing was all excellent.

预涂金属用自光固化聚氨酯丙烯酸酯低聚物合成光固化涂料的制备及性能

摘要 在本研究中，我们通过迈克尔加成反应合成了一种自光固化中间体，并合成了聚氨酯丙烯酸酯低聚物。通过将合成的低聚物和 HDDA/TMPEOTA 比率与反应性稀释剂混合来制备光固化涂料。使用棒涂机分别将薄膜涂覆到玻璃板和基底处理金属板上，厚度分别为 120 μm 和 30 μm。机械性能随着交联密度的增加而增加。当TMPEOTA含量为6或8wt%时铅笔硬度测试最好，当TMPEOTA含量小于10wt%时，附着力和条带测试显示出优异的物理性能。MEK 摩擦非常好。
