Abstract

The invention discloses a coating formula for an oven surface. The coating formula for the oven surface is characterized by comprising, in percentages by weight, 15-20% of epoxy resin, 17-20% of polyester fiber, 12-15% of a curing agent, 5% of an auxiliary, 10% of a leveling agent, 10-12% of barium sulfate, 5-8% of titanium dioxide, 1% of high-gloss wax, 2% of color master batch, 3% of an electricity-increasing agent, 5% of an anti-sedimentation agent and 5% of a mould inhibitor, wherein the sum of the percentages of the components is equal to 100%. The coating 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 formulation for the surface layer of an oven. 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-...
