Abstract

The invention discloses a preparation method of water-repellent and oil-repellent anhydride-based fluorine-containing acrylate resin, and method for preparing a water-repellent and oil-repellent paintand coating prepared based on the resin. Therefore, the preparation method comprises the following steps: firstly, carrying out free radical copolymerization on a fluorine-containing alkenyl monomer,a polymerizable non-fluorine monomer, unsaturated anhydride containing double bonds in the structure, other functional monomers and the like in a solvent, and firstly synthesizing novel fluorine-containing acrylate resin MPFA containing fluoroalkyl, anhydride group and other functional groups in the structure; then, using the resin as a film-forming substance, then grinding and blending the resinwith a nano pigment filler, a dispersing agent and the like to prepare a coating, and performing cross-linking thermocuring under the action of a polyepoxy compound or a polyamino compound curing agent so that a resin coating with good flexibility, impact resistance and water repellent effect is prepared, and the antifouling grade of the coating can reach the 02 grade.
