The present invention relates to the field of powder coatings, and specifically discloses an outdoor matte two-component dry-blended powder coating, comprising component A, component B and an external matting agent. Component A comprises: 583–575 g of polyester resin A, 65–75 g of triglycidyl isocyanurate, 5–15 g of leveling agent, 3–5 g of benzoin, 3–5 g of PE wax, 247–267 g of barium sulfate, 20 g of matting filler and 5 g of carbon black. Component B comprises: 600–744 g of polyester resin B, 25–31 g of triglycidyl isocyanurate, 5–15 g of leveling agent, 3–5 g of benzoin, 3–5 g of PE wax, 247–267 g of barium sulfate, 20 g of matting filler and 5 g of carbon black. The powder coating is prepared according to the following steps: S1: take raw materials and put them into a twin-screw extruder respectively, and extrude into sheet A and sheet B respectively; S2: put sheet A and sheet B into an ACM pulverizer respectively, and pulverize into powder A and powder B respectively; S3: sieve and classify powder A and powder B to obtain base powder A and base powder B respectively; S4: mix and sieve base powder A, base powder B and external matting agent to obtain the powder coating.
