摘要
制备了具有核壳结构的抽陛聚氨酯-丙烯酸酯(WPUA)复合分散体。研究了NCO/OH摩尔比、醇扩链剂、亲水性扩链剂、E-20、MMA等对分散体及涂膜性能的影响,从而确定了最佳合成配方,获得了低温成膜性好、贮存稳定性好、高硬度、耐水性佳的水性聚氨酯分散体及其涂料。
Water-borne polyurethane/acrylate dispersion(WPUA)with core/shell structure was prepared.The influences of ratio of NCO/OH,and chain extender etc.upon the performance of the dispersion and its film were discussed.An excellent polyurethane dispersion with good flexibility,stability,high hardness,good water-resistance was obtained.
