Abstract The study investigates the effect of the addition of phenyl phosphine oxide (DAPPO) with acrylate functionality, polyhedral oligomeric silsesquioxane (POSS) (acr-POSS) with acrylate functionality and 1H,1H,2H,2H-Perfluorodecyl acrylate (PFOA) on the superhydrophobicity and fire-resistance of photo-curable urethane-acrylate coatings. The addition of DAPPO to urethane-acrylate (50 wt.%) improved flame resistance. The additions of acr-POSS and PFOA improved surface hydrophobicity through increasing surface roughness by the addition of acr-POSS and decreasing surface energy by the addition of PFOA. The flammability and surface properties of the photo-curable hybrid coatings were evaluated by measuring limiting oxygen index (LOI) and water contact angle (WCA), respectively. Compared with the only urethane-acrylate-containing coating, the final hybrid coating had an increased water contact angle from 72.7°±2 to 147.2°±2 and increased LOI from 17,0 ± 0.08–24,3 ± 0.08. In the final hybrid coating, extinguishing occurred in less than 10 s.

设计超疏水和阻燃光固化混合涂层

摘要 本研究研究了添加具有丙烯酸酯官能团的苯基氧化膦 (DAPPO)、具有丙烯酸酯官能团的多面体低聚倍半硅氧烷 (POSS) (acr-POSS) 和 1H,1H,2H,2H-全氟癸基丙烯酸酯 (PFOA) 的影响。光固化聚氨酯丙烯酸酯涂料的超疏水性和耐火性。将 DAPPO 添加到聚氨酯丙烯酸酯 (50 wt.%) 中可提高阻燃性。添加acr-POSS和PFOA通过添加acr-POSS增加表面粗糙度并通过添加PFOA降低表面能来改善表面疏水性。分别通过测量极限氧指数（LOI）和水接触角（WCA）来评估光固化混合涂层的可燃性和表面性能。与唯一含聚氨酯丙烯酸酯的涂料相比，最终混合涂层的水接触角从 72.7°±2 增加到 147.2°±2，LOI 从 17,0 ± 0.08–24,3 ± 0.08 增加。在最后的混合涂层中，灭火发生在不到 10 秒。
