Normal temperature cured type fluorine-silicon copolymerization coating resin and preparation method thereof

The invention relates to a normal temperature cured type fluorine-silicon copolymerization coating resin, and particularly relates to a normal temperature cured type fluorine-silicon copolymerization coating resin which is synthesized through solution polymerization by taking a fluorine-containing olefin monomer and organic silicon as main comonomers. The normal temperature cured type fluorine-silicon copolymerization coating resin comprises the following raw materials in percentage by weight: 30%-45% of trifluorochloroethylene, 5%-20% of organic silicon monomers, 10%-35% of ester monomers, 5%-8% of hydroxyalkyl olefin ethers, 1%-7% of undecylenic acid, 35%-45% of organic solvents and 0.5%-1% of initiating agents. The normal temperature cured type fluorine-silicon copolymerization coating resin disclosed by the invention can be cured at normal temperature by being matched with a polyurethane curing agent and also be cured in a heating way, has lowered surface, enhances self cleaning and is low in friction coefficient after being formed into a film compared with FEVE (Fluoro Ethylene-Vinyl Ether copolymer) type fluorine-carbon coating because fluorine-containing olefin and the organic silicon are copolymerized, keeps excellent adhesive force, has the advantages of preeminent weather resistance, water resistance and grease resistance and enhances the contamination resistant property of coating.
