A high-temperature-resistant, anti-aging low-VOC polyurethane anti-corrosion coating, which is composed of two components, A and B. Component A consists of 10-20 parts of polyphenylene ring polyester polyol resin, 40-60 parts of pigments and fillers, 20 parts of ~40 parts of solvent and 1~3 parts of additives. The B component is multifunctional polyisocyanate. The A and B components are mixed and stirred according to the weight ratio of 10:0.5~1.5. The solvent of component A is a combination of tert-butyl acetate, dimethyl carbonate and dibasic acid ester, which has the characteristics of low toxicity and low VOC content; component B uses solvent-free isocyanate resin, which further reduces the VOC content of anti-corrosion coatings ; Nano-titanium dioxide and nano-silicon carbide are added to the filler, which improves the heat resistance of the polyurethane coating, making it heat-resistant up to 200 ° C, and enhancing the anti-corrosion performance of the coating.
