Abstract

The invention provides a powdery coating applied to wood finishing. The powdery coating is prepared from the following raw materials in parts by weight: 25 to 40 parts of modified epoxy resin, 1 to 3parts of a curing agent, 0.5 to 1 part of a pigment, 0.5 to 1 part of a degassing agent, 0.2 to 0.5 part of a dispersant, 0.5 to 1 part of a toughening agent, 0.2 to 0.5 part of a luster enhancing agent, 0.1 to 0.5 part of a wetting agent, 0.1 to 0.3 part of a preservative, 0.1 to 0.3 part of an antioxidant and 0.2 to 0.5 part of a light stabilizer, wherein an electricity enhancing agent is beta-hydroxyalkylamide; the degassing agent is stearic acid; the dispersant is zinc thionate; the toughening agent is a pvc (polyvinyl chloride) toughening agent; the wetting agent is heptadecylimidazoline;the preservative is 5-chloro-2-methyl-4isothiazoline-3-one. The raw materials are mixed and crushed and then are extruded; then a mixture is subjected to sheet preparation, shearing, crushing and sieving to obtain the powdery coating. According to the powdery coating provided by the invention, the modified epoxy resin is added and the antioxidant and the light stabilizer are introduced, so that the problems that the storage stability is poor, the leveling property is not good and the curing temperature is too high are remarkably solved.

Description

technical field [0001] The invention belongs to the field of coating preparation, and in particular relates to a powder coating applied to wood coating and a production method thereof. Background technique [0002] Powder coating is a new type of high-performance and environmentally friendly coating. Compared with traditional coatings, it has the following advantages: ① It does not contain solvents and is a 100% solid system; ② The utilization rate of coatings can be as high as 95% during the coating process; ③ The performance and durability of the coating layer of powder coatings are greatly improved compared with solvent-based coatings; ④One-time coating is equivalent to the thickness of solvent-based coatings from a few microns to tens of microns, which saves time, energy and high efficiency; It is necessary to adjust the viscosity with the seasons, the thick film is not easy to sag and it is easy to realize automatic production; ⑥It is easy to maintain the sanitation of ...
