Abstract

The invention discloses a method for preparing a water-repellent and oil-repellent anhydride-based fluorine-containing acrylate resin and a method for preparing a water-repellent and oil-repellent coating and a coating based on the resin. For this reason, the present invention first carries out free radical copolymerization of fluorine-containing alkenyl monomers and polymerizable non-fluorine monomers, unsaturated acid anhydrides containing double bonds in the structure, and other functional monomers in a solvent, and first synthesizes 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 material, and then the resin is ground and blended with nano-scale pigments and fillers, dispersants, etc. Under the action of epoxy compound or polyamino compound curing agent, cross-linking heat curing not only produces a resin coating with flexibility, impact resistance and good water repellency, but also the anti-fouling level of the coating can reach 0‑2.

Description

technical field [0001] The invention belongs to the field of functional resin coatings, and in particular relates to a preparation method of anhydride-based fluorine-containing acrylate resin and its application in coatings and coatings. Background technique [0002] Fluorine-containing acrylate resin, low surface energy, excellent water and oil repellency, used in the treatment of glass, metal or fiber substrates, etc., can not only improve the surface properties of the substrate, but also endow the substrate with ideal water and oil repellency and Antifouling performance, so it is widely used in the field of functional coatings and coatings. [0003] Copolymerize fluorine-containing acrylate or fluorine-containing alkenyl compound with aliphatic acrylate, functional monomer, etc., to synthesize organic fluorine resin with excellent water and oil repellency, which can be found in patent documents CN102443099, CN101538342, CN101759835, CN1166709, CN1315886 and so on.
