Problems solved by technology

[0002] The traditional aluminum-silver powder coating is a branch of fine art coatings. Due to the differences in pigment stability, resin compatibility and processing dispersion, it is difficult for many powder coating manufacturers to combine the primary index and The secondary indicators are perfectly unified, especially due to the oxidation of aluminum and the migration in the coating film, this series of powder coatings are easy to oxidize and blacken, and their wear resistance is greatly reduced, so it is difficult to guarantee the durability of their powder coatings. metal effect
[0003] Thermosetting powder coatings are solid powdery synthetic resin coatings composed of solid resins, pigments, and related additives. Most of the domestic thermosetting powder coatings are used for indoor household appliances and metal furniture products. When spraying outdoors, due to the coating surface It is often polluted by dust and oil stains, which is not easy to remove, thus affecting the application of thermosetting powder coatings

Embodiment 1

[0025] Take 20 parts of polyester resin, 1 part of triglycidyl isocyanurate, 3 parts of barium sulfate, 2 parts of light calcium carbonate, 0.5 parts of titanium dioxide, 1.5 parts of non-floating aluminum powder, and 0.5 parts of fluorine surfactant. After mixing in a rotary self-turning mixer, it is melted and extruded in a mixing extruder, cooled, sliced ​​by a tablet press and slicer, and then pulverized by an ACM-10 pulverizer, mixed and packaged into a finished product. The appearance of the paint is uniform in color, loose without agglomeration, and the fineness (0.09mm square hole sieve) sieve residue is ≤0.3%. Horizontal melt fluidity (180℃±2℃) / min 20~28mm.

Embodiment 2

[0027] Take 22 parts of polyester resin, 2 parts of triglycidyl isocyanurate, 5 parts of barium sulfate, 3 parts of light calcium carbonate, 0.8 parts of titanium dioxide, 2 parts of non-floating aluminum powder, 0.8 parts of fluorosurfactant, and process Technology is with embodiment 1.

Embodiment 3

[0029] Take 25 parts of polyester resin, 3 parts of triglycidyl isocyanurate, 8 parts of barium sulfate, 4 parts of light calcium carbonate, 1 part of titanium dioxide, 3.5 parts of non-floating aluminum powder, and 1 part of fluorosurfactant, An appropriate amount of Tillandsia, high black, processing technology with embodiment 1.
