摘　　要：为满足液化天然气(LNG)储罐外防腐涂层体系的环保要求,开发适用于LNG储罐的水性防腐涂层体系就显得非常重要。文中以水性丙烯酸羟基乳液为成膜物质,水性异氰酸酯为固化剂制备了适用于LNG储罐的水性聚氨酯面漆。结果表明,所制备的LNG储罐水性防腐涂层体系性能优异,可以替代液化天然气LNG储罐防腐涂层体系中溶剂型面漆,满足当今的环保要求。In order to meet the environmental requirement of the external protection of LNG storage tanks,it is very important to develop a water-based coatings system suitable for LNG storage tanks.In this paper,a waterborne polyurethane topcoat for LNG storage tanks was described that was prepared by using aqueous hydroxyl acrylic latex and aqueous Isocyanate as crosslinker.The results showed that the water-borne anti-corrosion coatings system for LNG storage tanks provided excellent performance and could be used as anti-corrosion coatings system to replace the solvent-based paint for LNG storage tanks.
