摘要
采用可再生资源环氧大豆油(ESBO)作为原料与二氧化碳反应合成环碳酸酯基大豆油(CSBO),再通过CSBO与乙二胺及二乙烯三胺分别反应制备非异氰酸酯聚氨酯(NIPU)预聚体;以其作为固化剂与环氧树脂E-51反应制备环氧-非异氰酸酯聚氨酯杂化涂膜。通过FT-IR对NIPU预聚物结构进行分析,证明了聚氨酯特征基团氨基甲酸酯键的生成;所制备的清漆涂膜综合性能优良,对比纯环氧体系,其耐化学性、耐磨性能更优异;同时其制备过程中不使用有毒性的异氰酸酯,安全环保。
The cyclic carbonate soybean oil(CSBO) was prepared by using the renewable resources soybean oil and carbon dioxide, then the non -isocyanate polyurethane(NIPU) prepolymer with the amino was systhesised by the reaction between the CSBO and the ethylene diamine and diethylene triamine respectively. The epoxy - NIPU hybrid coating was prepared by using NIPU as the curing agent and epoxy resin. The formation of urethanes group, the characteristic group of PU, was verified by FT - IR analysis. The hybrid coating showed high performance, especially the exc, ellent chemical resistance and wear resistance. The preparation process was safe and environment frendily, as no use of the toxic isocyanate.
