Abstract

The invention discloses a formula of composite powder coating. The formula of the composite powder coating involves, by weight, 32-42% of acrylic polyol resin, 18-21% of a curing agent, 3% of an auxiliary, 3% of a leveling agent, 10-15% of barium sulfate, 5-6% of titanium dioxide, 2% of a color masterbatch, 3% of an electric power increasing agent, 5-6% of an antioxidant and 6-12% of an anti-gas agent, wherein the quantity sum of the components is equal to 100%. The formula of the composite powder coating has the advantages that the coverage performance is good and the cost is low.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a formula of composite powder coatings. Background technique [0002] Powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. In the prior art, its powder coating is composed of polyester resin, blocked isophor copper diisocyanate, benzoin and dibutyltin dilaurate. Its disadvantages are poor physical properties, poor covering effect, and easy generation of fine bubbles. Unable to meet electrical spraying and surface protection. That is, the existing powder coatings have poor coverage and cannot meet the needs of production and life. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defici...
