The invention relates to the field of automotive interior coatings, in particular to an interior water-based scratch-resistant matte black coating and a preparation method thereof, which are used for solving the problems that the existing automotive interior coating is poor in scratch resistance, and obvious scratches are generated when the coating is scratched by nails or under external acting force, so that the appearance of a paint film is influenced; the paint film does not have the problems of soft touch feeling and self-repairing capability; according to the preparation method, the water-based flexible acrylic resin, the water-based polyester resin, the polytetrafluoroethylene wax and the nano polymer aid are utilized, so that the product has better scratch resistance and wear resistance, the leveling aid is mainly composed of modified organic silicon, the surface tension is lower, the surface is smooth, and the water-based acrylic resin is stable in molecular structure, good in water resistance and goo
