The invention discloses a method for preparing a water- and oil-repellent anhydride-based fluorine-containing acrylate resin and a method for preparing a water- and oil-repellent paint and coating based on the resin. To this end, the present invention firstly conducts free radical copolymerization of a fluorine-containing alkenyl monomer with a polymerizable non-fluorine monomer, an unsaturated acid anhydride containing a double bond in the structure, and other functional monomers in a solvent, and firstly synthesizes the structure containing fluorine. A new type of fluorine-containing acrylate resin MPFA with hydrocarbon groups, anhydride groups and other functional groups; then, the resin is used as a film-forming substance, and the resin is ground and blended with nano-pigments, fillers, dispersants, etc. to make coatings, and then used in many Cross-linking thermal curing under the action of epoxy compound or polyamino compound curing agent not only produces a resin coating with good flexibility, impact resistance and water repellency, but also the antifouling grade of the coating can reach 0-2. |
