The present invention discloses a wear-resistant polyester resin powder coating and a preparation method thereof, belonging to the technical field of coatings. The preparation of the polyester comprises the following steps: mixing and stirring 2,2-dimethylolbutanol, 2,2-dimethylolpropionic acid and p-toluenesulfonic acid in a reaction kettle, reacting and performing reduced-pressure reaction to obtain material A; adding 2,2-dimethylolpropionic acid and p-toluenesulfonic acid, reacting and performing reduced-pressure reaction to obtain material B; adding 2,2-dimethylolpropionic acid and p-toluenesulfonic acid, reacting, discharging, grinding and sieving to obtain the polyester. The preparation of the wear-resistant polyester resin powder coating comprises the following steps: mixing and crushing the polyester, wear-resistant filler, triglycidyl isocyanurate, Tego 410 leveling agent, benzoin, coupling agent RC201 and oxidized polyethylene wax, adding into a twin-screw extruder for mixing, extruding, cooling, crushing and sieving to obtain the wear-resistant polyester resin powder coating.
