The paint formula comprises, by weight, 20-29% of epoxy resin, 15-17% of curing agents, 3-5% of auxiliaries, 7-8% of flatting agents, 16-20% of barium sulfate, 2% of sensitizers, 11-18% of titanium dioxide, 1% of high light wax, 2% of color master, 3-5% of electric power increase agents, 4-7% of antioxidants and 1% of silicon carbide, and the weight sum of the components is equal to 100%. The paint formula has the advantages of good covering performance and low cost.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a coating formula suitable for the surface layer of microwave ovens. 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 overco...
