The invention discloses a high-performance anti-icing paint used for high speed bullet trains, and a preparation method thereof. The high-performance anti-icing paint used for high speed bullet trains is composed of a paint main ingredient, a polyurethane curing agent, and a diluent; the paint main ingredient is composed of fluorocarbon resin, silicon modified acrylic resin, an anti-aging auxiliary agent, a levelling agent, and an antifoaming agent; the polyurethane curing agent is composed of an aliphatic isocyanate polymer, and butyl acetate; and the diluent is composed of butyl acetate, and propylene glycol methyl ether acetate. The high-performance anti-icing paint is prepared via combination of the above three ingredients. It is confirmed by test and applications that the high-performance anti-icing paint is high in adhesive force, impact resistance, flexibility, weatherability, and possesses excellent long-lasting anti-icing capacity; and cleaning is convenient.
