The invention particularly relates to an environment-friendly FEVE (trifluorochloroethylene copolymer) fluorocarbon coating and a preparation method thereof. The environment-friendly FEVE fluorocarbon coating is prepared from, by weight, 20-30 parts of an FEVE emulsion, 20-30 parts of epoxy-based silane modified silica sol, 1.0-2.0 parts of a coalescing agent, 0.1-1.0 part of a viscosifier, 0.2-1.0 part of a polyurethane thickening agent and 30-60 parts of color paste; the color paste is prepared from, by weight, 33% of water, 0.3% of a multifunctional agent, 0.3% of a cellulosic thickener, 0.4% of a wetting agent, 0.9% of a dispersing agent, 0.1% of a defoamer, 47% of titanium dioxide, 9% of mica powder and 9% of wollastonite powder. The environment-friendly FEVE fluorocarbon coating is free from organic solvents of benzene, methylbenzene, xylene, ethylbenzene and the like and harmful substances like free diisocyanate to human bodies and environment, excellent in alkali resistance, water resistance, aging resistance, corrosion resistance, washability, adhesive force and strain resistance and broad in market prospect.
