This invention belongs to the field of water-based coating technology and relates to a water-based sealing coating for passenger vehicles with anti-flash rust function. By weight, it comprises 10-20 parts Fischer-Tropsch wax, 15-20 parts sulfonated lanolin cerium / lanthanum salt, 30-70 parts water, 1-4 parts dimethyl ethanolamine phenanthreneate, 2 parts dihydrazide terephthalate, and 1-5 parts isomeric tridecyl alcohol polyoxyethylene ether TO-8 modified with ethyl acetoacetate methacrylate. It primarily addresses the problem of flash rust on the inner walls of car door cavities and other body seams when using water-based products, and solves the corrosion problem caused by long-term inward evaporation of moisture from door cavities and seams when applying thick coatings. This invention uses dimethyl ethanolamine phenanthreneate at a moderate vapor pressure to ensure emulsification properties while its vapor-phase corrosion inhibition function prevents flash rust. Furthermore, as moisture and amine gradually evaporate, the self-crosslinking of the ketone carbonyl-hydrazide groups gradually decreases the HLB value of the system, giving the coating good water resistance in the early stages of drying, achieving a perfect water-based alternative.
