Description

Technical Field

[0001] The utility model relates to the technical field of powder coatings, in particular to a powder coating mixer. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is not solvent and water, but air. Powder coating is made by mixing special resin, pigment, filler, curing agent and other additives in a certain proportion, and then prepared by hot extrusion, crushing and screening.

[0003] After searching, it was found that there is a powder coating mixer with publication number CN217164209U, which includes a mixing barrel and a bracket. The mixing barrel is fixedly mounted on one side of the vertical end of the bracket to solve the problem that some coating powder adheres to the barrel wall and is difficult to discharge when the mixing barrel is discharging materials. In this practice, a rib fan-like stirring blade is used to stir the material, which cannot effectively turn the material up and down, and the mixing effect is average. For this reason, we propose a powder coating mixer. Utility Model Content
