In this paper，through the two-step polymerization process，fluorinated acrylicacid monomer was added into the synthesis of conventional hydroxyl acrylic acid resindispersion，the high gloss and high endurance aqueous fluorinated hydroxyl acrylic acidsecondary dispersion（FHAD）was successfully prepared. The effects of the type and content offluorinated acrylic acid monomer on the properties of FHAD were investigated. The experimental results showed that when hexafluorobutyl methacrylate（HFBMA）was added and the content was 8%，the dispersion owned small particle size，moderate viscosity and excellent heat storage stability. Meanwhile，the two-component coatings prepared with the dispersionand water-based isocyanate curing agent AQUAPU-298 owned the excellent gloss. The glossof 20°，60° and 85° was 83. 6，93. 9 and 99. 5 respectively. What’s more，the acid and alkali  resistance of films had been greatly improved and the water resistance（25 ℃）could achieve 312 hours，significantly improved the endurance of conventional acrylic dispersion.
