The application discloses a kind of deep matting outdoor polyester resin powder coating and preparation method thereof, it is related to powder coating technical field.The coating includes the following weight parts components: saturated end carboxyl polyester resin 50-70 parts, polyhedral oligomeric silsesquioxane hollow mesoporous silica hybrid matting agent 2-8 parts, polysiloxane 0.5-3 parts, curing agent 3-8 parts, filler 10-30 parts, leveling agent 1-5 parts, degassing agent 0.5-3 parts, pigment 5-15 parts, auxiliary agent 0.5-3 parts;The hybrid matting agent is grafted amino cage silsesquioxane and is hollow mesoporous silica by titanium ester lipophilic end-capped.The coating can effectively inhibit matting agent high-temperature agglomeration and pore hygroscopicity by the synergistic effect of three-dimensional hybrid skeleton steric hindrance, mesoporous channel multiple scattering and shell end-capped micro-isolation, so that product has extremely low gloss, smooth and delicate leveling appearance, high mechanical strength and excellent outdoor long-acting weather resistance.
