Disclosed in the present invention is a modified aqueous FEVE fluorocarbon coating. The modified aqueous FEVE fluorocarbon coating comprises the following raw materials in part by weight: 40-70 parts of a modified FEVE dispersion solution, 5-10 parts of a nanometer silica gel sol, 1-5 parts of a curing agent, 10-35 parts of a pigment and filler, 5-15 parts of an auxiliary agent, 1-10 parts of a cosolvent, and 5-30 parts of deionized water. From the viewpoint of molecular design, the present invention innovatively introduces a hydrophilic structural monomer having a functional group to realize the purposes of improving the compatibility of a resin system with water and increasing the film-forming adhesion force of a resin, and sets a specific modified FEVE dispersion solution and nanometer silica sol compounding system, thereby obtaining the modified aqueous FEVE fluorocarbon coating having comprehensive performance comparable to that of an existing solvent-based fluorocarbon coating. |
