Waterborne multicolor paint as well as preparation method and application thereof

The invention provides a water-based multicolor coating as well as a preparation method and application thereof, and particularly relates to the technical field of coatings. The water-based multicolor coating is prepared from the following components in parts by weight: 300 to 500 parts of a base material, 200 to 400 parts of protective glue and 200 to 400 parts of a continuous phase, each of the base material and the continuous phase comprises a non-toxic antibacterial and mildew-proof agent SMP-AT, and the parts by weight of the SMP-AT are respectively 1-3 parts independently. According to the water-based multi-color paint provided by the invention, by introducing the environment-friendly inorganic antibacterial mildew preventive SMP-AT, the mildew and corrosion resistance of a dry film and a wet film of the water-based multi-color paint is improved, the viscosity stability of the multi-color paint is improved, the storage stability is improved, and the green, environment-friendly and healthy multi-color pa
