A modified method for preparing fluorocarbon coating trifluoromethyl type feve

The present invention relates to type-trifluoromethyl FEVE fluorocarbon resin, especially a method of preparing a nano type material modification trifluoromethyl FEVE fluorocarbon coating, a silane coupling agent KH? Alkoxy is hydrolyzed to a hydroxyl group 570, the surface of the belt nano SiO2 having hydroxyl condensed to form covalent bonds, and the nano SiO2 chemically generated between polystyrene (PS) molecular bonding, so that the polystyrene-coated nano-SiO2 surface, forming the core? shell structure, increase in organic solvents dispersibility; was then added to the modified nano-SiO2-trifluoromethyl-type fluorocarbon resin in a composite FEVE fluorocarbon coating, improved adhesion of fluorocarbon coating has been reached, the UV resistance, acid and alkali resistance , stain resistance and corrosion resistance purposes.
