Problems solved by technology

[0002] Ordinary fluorine-containing polyurethane enamel is generally composed of hydroxyl fluorine-containing resin, aliphatic isocyanate, coloring pigments, additives, solvents, etc. Its physical and chemical properties can meet the requirements of new production and repaired aircraft, and its salt spray resistance can reach 2000 hours. Hours, 5000 hours of artificial aging resistance, it is a super weather-resistant heavy-duty anti-corrosion coating, which can meet the use requirements of our army's third-generation aircraft, but it does not have other functions, so it cannot meet the country's use requirements for new fighters

Abstract

The invention provides a bi-component fluorinated polyurethane enamel paint with high emissivity and a preparation method thereof. The bi-component fluorinated polyurethane enamel paint is formed by a component A and a component B at weight ratio of 100:(20-45); except a high infrared emitting function, the paint still has super weather fastness of the fluorinated polyurethane enamel paint; the artificial aging resistance can reach 5000 hours; the corrosion resistance is ultrahigh; the paint can resist against water for 96 hours at 38 DEG C and can resist against high-temperature lubrication oil for 24 hours; the adhesive force is excellent; the paint can resist against humidity and heat for 1000 hours and salt mist for 2000 hours; the paint is mainly applied to outdoor severe environments, such as, high-temperature high-humidity strong ultraviolet irradiation areas, seaborne and near coast areas and military or civil use fields with high demand on emissivity in medium far infrared wave band, such as airplane, equipment, facilities and vehicles; and the preparation method is simple and can meet the requirement of large-scale industrial production.
