摘要： 合成具有足够疏水和疏油性能的水性含氟丙烯酸树脂，全部采用含氟丙烯酸酯单体，其在提供树脂具有疏水和疏油性能的同时，也会带来树脂容易起泡和稳泡的缺陷，为此，采用开环聚合合成环硅氧烷预聚物，将环硅氧烷预聚物引入水性含氟丙烯酸树脂分子链中，可以消除因含氟单体引入产生的起泡和稳泡缺陷。

Abstract: The waterborne fluoro modified acrylic synthesized fully with fluluorinated acrylate monomer will provide both hydrophobic and oleophobic properties, but cause the problems of foaming and foam stabilization at the same time. In order to avoid this probler, a cyclic siloxane prepolymer was synthesized by ring opening polymerization, which was then introduced into the fluoro-contaning acrylic resin chain acrylic by free radical polymerization, eliminating the defect of foaming and foam stabilization. In addition, the devlopment of waterbone of fluorine silicone modified acrylic resin has a significance on environmental protection.
