Abstract

The invention discloses a coating formula suitable for a surface layer of a refrigerator. The coating formula comprises the following components in percentage by weight: 31-40% of epoxy resin, 15-19% of a curing agent, 6% of an auxiliary, 3% of a flatting agent, 10-15% of barium sulfate, 1% of an optical brightener, 5-6% of titanium dioxide, 1-2% of color master batch, 2% of a power increasing agent, 5-7% of an antioxidant, 7-12% of a fuel gas resisting agent and 1% of silicon carbide, based on 100% in total. The coating 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 formulation suitable for the surface layer of a refrigerator. 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 ove...
