Keyword:  聚氨酯脲-丙烯酸酯复合水分散液有机硅氧烷微乳液改性水分散液表面性能疏水性能;
Abstract: 用N-β.氨乙基-γ-氨丙基三甲氧基硅烷、辛基三乙氧基硅烷与表面活性荆OP-10,制备了室温贮存稳定性大于6个月的有机硅氧烷微乳液。后者与聚氨酯脲-丙烯酸酯(PUA)复合水分散液共混。制备了改性PUA复合水分散渡,并通过FT-IR、ATR、粒度分析、Zeta电位对改性水分散液以及成膜后的表面性能进行了表征。实验结果表明,与PUA复合水分散液相比,改性水分散液的粒径减小,粒径分布变宽。改性水分散液成膜后,表面呈现出很好的疏水性能和较低的表面能,与成膜过程中有机硅氧烷在膜表面的富集效应有关。
