Abstract: A high performance and ambient-curable silicone modified CTFE fluororesin emulsion was prepared by emulsification after solution polymerization method using vinyl triethoxysilane(ETOS),chlorotrifluoroethylene(CTFE),undecylenic acid(UA),hydroxybutyl vinyl ether(HBVE),n-butyl vinyl ether(BVE) and cyclohexyl vinyl ether(CHVE) as raw materials.The effects of monomer and emulsifier on the properties of emulsion were studied.The hardness,adhesion,impact strength and boiling resistance of fluororesin emulsion film were analyzed,and the emulsion film was analyzed by FT-IR,DSC,TGA and SEM.Results showed that the resin with better performance can be achieved under the following conditions:1∶1 the molar ratio of BVE to CHVE and 5%(wt,quality score,the same below) mass fraction of ETOS.After curing,the emulsion coating had 2H hardness,0 level adhesion,more than 50kg·cm impact strength,high boiling resistance ability,and the glass transition temperature was 28.66℃.
