Abstract

Two non-isocyanate polyurethanes (NIPUs) were used as reactive diluents for an alkyd to obtain eco-friendly new UV-curable alkyd-polyurethane coatings. A linseed-based alkyd resin was prepared and formulated with the reactive diluents (NIPUs) and free radical photoinitiator, and then UV-cured. NMRs were used to characterize the alkyd and NIPUs and glass transition temperature (Tg) of cured alkyd-polyurethanes were evaluated by using DSC. Further, spectroscopy and thermal stability of the coatings were evaluated by using ATR-IR spectroscopy and thermogravimetric analysis (TGA), respectively. Moreover, coating properties such as pencil hardness, cross-cut adhesion, pull-off adhesion, impact resistance, and reverse impact resistance were also evaluated. It was found that crosslink density, pencil hardness, adhesion, and Tg were dependent and proportional to the amount of the NIPUs (reactive diluents) showing significant improvement in mechanical and thermal properties compared to the linseed-based alkyd resin.

环保型紫外光固化醇酸基非异氰酸酯聚氨酯
采用两种非异氰酸酯聚氨酯(nipu)作为醇酸反应稀释剂,制备了一种新型的可紫外光固化醇酸聚氨酯涂料。以活性稀释剂(NIPUs)和自由基光引发剂为原料制备了亚麻籽基醇酸树脂,并进行了紫外光固化。用nmr表征了醇酸和nipu,用DSC评价了固化后醇酸聚氨酯的玻璃化转变温度(Tg)。利用ATR-IR光谱和热重分析(TGA)分别对涂层的光谱和热稳定性进行了评价。此外,还评估了涂层的铅笔硬度、横切附着力、拉脱附着力、抗冲击性和抗反向冲击性等性能。研究发现,与亚麻籽基醇酸树脂相比,交联密度、铅笔硬度、附着力和Tg与nipu(反应稀释剂)的用量成正比,在机械和热性能上有显著改善。
