Self-cleaning fluoroethylene vinyl ether (FEVE) fluorocarbon coating and preparation method thereof

The invention belongs to the technical field of coatings, and particularly relates to a self-cleaning fluoroethylene vinyl ether (FEVE) fluorocarbon coating and a preparation method of the self-cleaning FEVE fluorocarbon coating. The self-cleaning FEVE fluorocarbon coating consists of a component A and a component B according to a mass ratio of (7-15):1; the component A comprises the following components in percentage by mass: 36-50% of FEVE fluorocarbon resin, 0.5-2% of a wetting dispersant, 1-2% of zinc powder, 7-12% of amorphous silicon dioxide, 6-10% of graphite phase carbon nitride, 0.3-0.8% of a defoaming agent, 0.8-1.5% of a leveling agent, 18-25% of nano silica sol, 4-8% of hydroxyethyl cellulose and the balance of deionized water; and the component B is a polydiisocyanate curing agent. In conclusion, the self-cleaning FEVE fluorocarbon coating provided by the invention has good dustproof and anti-fouling effects, excellent self-cleaning performance, high weather resistance andsterilization characteri
