Water-based industrial metallic paint and preparation method thereof

The invention relates to a water-based industrial metallic paint and a preparation method thereof, belonging to the technical field of coating compositions. The water-based industrial metallic paint is mainly prepared from water and the following components in parts by weight: 20-50 parts of base material, 10-20 parts of magnetic ferrite powder, 5-10 parts of zeolite powder, 3-8 parts of diatomaceous earth, 5-10 parts of modified or unmodified glass flake and 5-15 parts of mica powder. The magnetic ferrite powder of the waterborne industrial metallic paint has the magnetic property, and the adhesion of the coating to the substrate can be improved, the migration of the rust component to the surface of the coating is locked, and the flash rust resistance at the early stage and the corrosionresistance at the later stage are improved; zeolite powder and diatomaceous earth can adsorb small molecules of rust and free iron ions, and improve the anti-flash rust in the early stage and anticorrosion performance in the
