新型单组分聚氨酯防水涂料的研制

Study on New Type Monocomponent Polyurethare Waterproof Coating

由异氰酸酯、聚醚多元醇和各种助剂制成不含焦油、不含溶剂的单组分湿固化聚氨酯(PU)防水涂料。讨论了聚醚配比、体系中水份及酸碱度等影响因素。该涂料具有性能优良、使用方便、对环境无污染等优点。经济效益和社会效益显著 。

A tar-free and solvent-free mono-component morsture curable polyurethane waterproof coating was prepared from ployether polyols?isdcynate and various of aids. Some influence factors such as the mixture ratio of two polyether polyols, water and pH were discussed. The coating had some strong points, such as super property and using conveniently and non-pollution to environment. Economic benefit and social benefit were remarkable. It had wide developing prospects.
