为了制备高固含量、长期贮存稳定、可常温固化的含氟聚合物水性乳液，借鉴无皂乳液聚合技术在偏氟乙烯聚合过程中加入全氟或多氟烷基氧化胺型表面活性剂，以偏氟乙烯 -六氟丙烯（VDF-HFP）共聚物为种子乳液，丙烯酸类单体共聚物为壳层，通过优化共聚组分含量、聚合工艺条件，共聚改性制备高固含量聚偏氟乙烯水性乳液。结果表明：制备的水性 PVDF乳液固含量 40%~ 53%，放置 4个月仍保持颗粒原始状态，高速搅拌剪切未出现凝聚现象，常温固化后的漆膜外观平整光滑，表面无缺陷。经施工及涂膜性能测试评价，共聚改性 PVDF水性乳液喷涂、辊涂施工正常，漆膜综合性能与溶剂型 PVDF涂料相当。

In order to prepare a water-based emulsion of fluorinated polymer with high solid content，long time storage stability and room temperature curing，perfluorinated orpolyfluoroalkyl oxidized amine surfactants were added into the process of vinylidene fluoridepolymerization by soap-free emulsion polymerization. During the polymerization，vinylidene fluoride-hexafluorography（VDF-HFP）copolymer was used as the seed emulsion and acrylicacid monomer copolymer was used as the shell，by optimizing the content of the componentsand the polymerization process conditions to achieve the high solid content emulsion. The solidcontent of PVDF waterborne emulsion was 40%-53% and the emulsion still maintained the original state of the particles after 4 months. The emulsion did not appear condensationphenomenon after high-speed mixing shear，after curing at room temperature the films were level and smooth，and the surface had no defects. After construction and coating performance test，the results showed that copolymerization modified PVDF waterborne emulsion spraying and roller coating construction were normal，and the comprehensive performance of the paintfilms were comparable to the solvent-type PVDF coatings.
