Abstract

The invention discloses a pure epoxy powder coating material, which comprises, by weight, 100-120 parts of an epoxy resin, 12-18 parts of a curing agent, 2-3 parts of a leveling agent, 3-6 parts of high-gloss wax, 6-8 parts of a flame retardant, 4-8 parts of silicon carbide, 2-3 parts of color masterbatch, and 4-9 parts of an antioxidant, wherein the epoxy resin is a bisphenol A type epoxy resin and has the epoxy equivalent of 1400-2500 g/eq, and the antioxidant is N,N'-di-sec-butyl p-phenylenediamine. According to the present invention, the cost of the pure epoxy powder coating material prepared according to the formula is reduced compared to the coating material in the prior art, the whole film layer is stable after the product is subjected to spray molding, and the good use prospect isprovided.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a pure epoxy powder coating. 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 deficiencies and ...
