Stripping-resistant ethylene-tetrafluoroethylene copolymer powder coating and preparation method thereof

The invention belongs to the technical field of powder coatings, and particularly relates to a stripping-resistant ethylene-tetrafluoroethylene copolymer powder coating and a preparation method thereof. According to the ETFE powder coating disclosed by the invention, besides matrix resin, a fluorine-containing silane coupling agent, polyamide resin and POSS (Polyhedral Oligomeric Silsesquioxane)-based fluorine-containing acrylate resin are also added; the addition of the fluorine-containing silane coupling agent improves the mixing uniformity of the matrix resin and other components, and the addition of the polyamide resin and the POSS-based fluorine-containing acrylate resin improves the adhesion performance of the ETFE powder coating on the surface of a metal product, improves the peel strength of the coating, and can be used for corrosion prevention or insulation of the surface of a workpiece in many severe environments. The powder coating disclosed by the invention is also added with pigment, so that the
