Background
The powder coating is a novel solvent-free 100% solid powder coating, which is prepared by mixing, crushing and sieving film-forming resin, an auxiliary agent, pigment, filler and the like, needs electrostatic spraying and baking for film formation during coating construction, and has the characteristics of no solvent, no pollution, recoverability, environmental protection, energy and resource conservation, labor intensity reduction, high mechanical strength of a coating film and the like.
Because the powder coating does not contain a solvent, the powder coating does not contain the solvent to assist in leveling in the baking process, and the leveling is controlled mainly by the wetting action of the leveling agent and the viscosity and softening point of main film forming substances, namely polyester, epoxy, curing agent and the like. However, the powder coating is difficult to coat thin layers, solvent-based coatings are easy to form ultrathin coatings, the powder coating is difficult to achieve the effect during coating, the average minimum film thickness is 50-70 mu m, and when the film thickness is less than 40 mu m, the film layer is too thin, the leveling property of the film is poor, so that the appearance decorative effect is poor, and serious orange peel or pore phenomena are presented.
The leveling agent is a common paint auxiliary agent and can promote the paint to form a flat, smooth and uniform coating film in the drying film-forming process; the surface tension of the coating liquid can be effectively reduced, the permeability of the coating liquid is improved, the leveling property and uniformity of the coating liquid are improved, the possibility of generating spots and stains during brushing is reduced, the coverage is improved, and the formed film is uniform and natural. Many kinds of leveling agents are available, mainly including surfactants and organic solvents, and the kinds of leveling agents used in different paints are different.
If no additional leveling agent is used in the existing powder coating formula, the surface of the film layer is rough, the gloss is low, the internal binding property of the film layer is poor, and the impact property is poor. And the leveling agent used by the existing powder coating has poor leveling performance of a coating film, the application range of the leveling agent is limited, most of the leveling agent is viscous liquid and is inconvenient to add and use, and meanwhile, due to poor compatibility, the coating film gloss cannot meet the requirement because the coating film gloss is easy to interfere with each other.

The functions of the raw materials used in the invention are introduced as follows:
The polyester resin is a linear or slightly branched heterochain macromolecular compound formed by high-temperature polycondensation of polyalcohol and polybasic acid. The polyester resin is prepared from hydrogenated terephthalic acid, trimethylolpropane monoester, 2-dimethylolpropionic acid heptyl ester, hydroxypivalic acid neopentyl glycol ester, neopentyl glycol and other raw materials. Butyl propionate, heptyl propionate or neopentyl glycol propionate ester groups are retained in polyester chain segments in the preparation process of the polyester resin, and the obtained polyester resin has a low surface tension group in the molecular structure, so that the polyester resin still has outstanding self-leveling property even if no leveling agent is additionally added.
TGIC (triglycidyl isocyanurate) is white particles or powder, is a heterocyclic epoxy compound, has good heat resistance and weather resistance, adhesion and excellent high-temperature performance, and is used as a crosslinking curing agent of polyester powder coating.
