▎ 摘　　要

NOVELTY - Fluorine-containing alkyd environmentally-friendly coating is prepared by mixing modified fluorine alkyd resin, glycerol phosphorylcholine and 2,4-dichloro-6-methoxy-1,3,5-triazine to obtain modified fluorine alkyd fluorinated alkylene resin, and mixing with other auxiliary agent, is claimed. USE - The coating is useful in buildings, various hardware components, decoration of industrial products and machinery, vehicles, ships, airplanes and meters. ADVANTAGE - The coating has excellent corrosion resistance and flame retardant effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the coating, comprising (1) mixing the modified fluorine alkyd resin, glycerol phosphorylcholine, acetonitrile and triethylamine in a mass ratio of 1:1:0.1:50-2:3:0.2:50, reacting in nitrogen atmosphere at 10-20℃ for 2-3 hours, adding 2,4-dichloro-6-methoxy-1,3,5-triazine with 0.5-1.5 times the mass of glycerol phosphorylcholine, reacting at 400-600 revolutions per minute at 40-50℃ for 3-5 hours, adding 2,4-dichloro-6-methoxy-1,3,5-triazine with 0.5-1.5 times the mass of glycerol phosphorylcholine, reacting at 80-90℃ for 5-7 hours at 300-500 revolutions per minute, 80-90℃ rotary steaming for 60-90 minutes, drying at vacuum degree of -0.085 MPa and temperature of 80℃ for 24 hours to obtain flame-retardant fluorine alkyd resin, (2) mixing flame-retardant fluorine alkyd resin, silicone leveling agent BYK331, hydrogenated castor oil and cyclohexanone in a mass ratio of 20:1:0.5:0.5:0.3-20:3:1:0.7:0.5, stirring at 800-1800 revolutions per minute for 30-60 minutes, stirring at 2500-3500 revolutions per minute for 30-60 minutes, distilling at a vacuum of -0.09 MPa and 45-55℃ for 2-3 hours to prepare environmentally friendly fluorine-containing alkyd coating.
