CUI Xue-jun 1,2,LIU Chun-hai1,2,YANG Rui-song1,2,LIN Xiu-zhou1,2,GONG Min1,2(1.School of Material and Chemical Engineering,Sichuan University of Science & Engineering,Zigong 643000,China; 2.Key Laboratory of Material Corrosion and Protection of Sichuan Colleges and Universities,Zigong 643000,China)  
A water-based fluorocarbon paint was prepared via mixed nano-TiO2/Ag compound type antibacterial agent into fluorocarbon emulsion,and the obtained coating is of stain resistance and antibacterial properties on the metal surface.The effects of weight content of antibacterial agent on antibacterial and stain resistance properties as well as contact angle.The better content of the antibacterial agent is determined as 3%.The microstructure of coating was characterized by scanning electron microscope(SEM).The analysis results show that the surface is uniform distributed a layer of nano-particles,which makes the coating good stain resistance and antibacterial properties.The physicochemical properties of coatings were tested.The results conform that the coating is of good physicochemical properties and may be applied to finishing and protection fields for metal surface.
