Abstract

The invention discloses a two-in-one primer glue color sheet. The two-in-one primer and glue color sheet comprises a back paint layer, a substrate, a primer glue layer, a color film layer and a protective film layer, which are sequentially arranged from bottom to top, wherein a formula of the primer glue layer comprises the following components: 30 to 40 percent of polyester resin, 5 to 10 percent of melamine resin, 40 to 50 percent of a solvent, 5 to 10 percent of an additive and 5 to 10 percent of pigment. According to the two-in-one primer and glue color sheet, the problems of poor universality of a glue layer of a color sheet in the prior art and high production cost caused by adoption of twice drying and twice coating in a production and processing process are solved.

Description

technical field [0001] The invention relates to an improvement of the structure of a two-in-one primer glue watercolor plate for household appliances and a method for producing the primer glue watercolor plate. Background technique [0002] At present, the product structure of color steel plate PEM is substrate+primer+glue+PET composite film with two coatings and two drying structures. Common film types for PET composite molds include PET+PVC laminated film, PET+AL film, and ink-printed PET film. , hook thread PET+plated AL film, etc., due to the different types of PET composite molds, and the degree of adhesion of each composite cotton is different, it is necessary to match different glues when laminating to realize the film, which needs to be constantly replaced during the production process The glue is time-consuming and labor-intensive, and the versatility of the glue is poor; at the same time, because the color plate structure of this structure needs to produce a primer...
