| description | The present invention relates to preparation process of water thinned fluoric polymer emulsion for paint. The preparation process is one emulsion copolymerization process with trifluorochloro ethylene, alkyl vinyl ether or vinyl acetate, hydroxyl butyl vinyl ether, undecylenic acid and polyoxyethylene acrylate as monomers, non-ionic emulsifier NP and anionic ammonium perfluoro octoate as composite emulsifier, and composition of ammonium persulfate or potassium persulfate and sodium bisulfite as redox initiation system. The polymerization may be completed in room temperature and is simple, and the product has excellent chemical stability, mechanical stability and mechanical performance. The emulsion has relatively high fluorine content, so that the prepared paint has excellent corrosion resistance, weather resistance and antifouling performance. |
