Fluorine and silicone urethane topcoat compositions having high weather resistance and heat shielding and methods for preparing the same

摘要

The present invention relates to a high weather resistance fluorine and silicone urethane heat shielding top coat composition, and to a composition for a top coat capable of maintaining heat shielding performance for a long time by mixing a fluorovinyl resin by synthesizing a silicone acrylic polyol resin. The highly weather-resistant fluorine and silicone urethane thermal barrier coating composition of the present invention includes 20 to 70 parts by weight of a silicone acrylic polyol resin, 1 to 20 parts by weight of a fluorine vinyl resin, 15 to 30 parts by weight of a coloring pigment, and 1 to 20 parts by weight of an extender pigment. Wow, 0.1 to 10 parts by weight of a hollow pigment, 0.1 to 5 parts by weight of a fluidity adjusting additive, 0.1 to 1 parts by weight of a wetting and dispersing agent, 0.1 to 5 parts by weight of an epoxy adhesion promoter, and 0.01 to 0.1 parts by weight of a reaction accelerator 100 parts by weight of the main body including 0.1 to 1 parts by weight of an ultraviolet absorber, 0.1 to 1 parts by weight of an ultraviolet stabilizer, and 5 to 40 parts by weight of a solvent for the main body; And 8 to 25 parts by weight of a curing agent composed of a resin for a curing agent.
