摘要
甲基丙烯酸羟乙酯封端的水性聚氨酯预聚体与丙烯酸酯发生聚合 ,制备丙烯酸酯改性水性聚氨酯分散体。考察了工艺条件对分散体稳定性及成膜物性能的影响。同时用红外光谱和扫描电镜讨论了丙烯酸酯改性聚氨酯成膜物的结构特征 ,用热分析仪分析了膜的热稳定性能。
The title aqueous acrylate modified polyurethane dispersion has been prepared with acrylate and aqueous polyurethane prepolymer that is blocked with hydroxyethyl methacrylate.The influence of preparation technology on stability of dispersion and film performance is discussed.The film structure of the aqueous acrylate modified polyurethane is characterized by use of infrared spectrum and SEM;the thermal stability of the film is investigated by use of thermal analyzer.
