Abstract

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.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a high-performance anti-icing coating for high-speed trains and a preparation method thereof. Background technique [0002] Anti-icing coatings have a wide range of applications, but are rarely used in the rail transit industry. The traditional anti-icing method widely used in the rail transit industry is: spraying anti-icing reagents. This method is not permanent and requires repeated spraying, which is costly and pollutes the environment. [0003] Anti-icing coatings require low cohesion between coatings and ice: there are two forces between ice and coatings, one is van der Waals force and the other is electrostatic force. The van der Waals force is reflected in the hydrophobic nature of the coating, and the electrostatic force is reflected in the dielectric constant of the coating surface. Coatings with hydrophobic properties and a low dielectric constant on the surface h...
