The invention relates to a high-hardness and high-temperature resistant powder coating and its preparation method. The powder coating comprises modified acrylic resin, epoxy resin, modified filler, titanium dioxide, curing agent and dispersant. The preparation process includes mixing and kneading modified acrylic resin, epoxy resin and modified filler, melt-extruding and granulating by a twin-screw extruder. Titanium dioxide, curing agent and dispersant are added for secondary extrusion, granulation, crushing and screening to obtain the final product. The cured coating film delivers outstanding high-temperature resistance and mechanical strength.
