A kind of manufacturing method of aluminum plate decorative painting

Abstract

The invention relates to a manufacturing method of an aluminum plate decorative picture. The manufacturing method comprises the steps of selecting an aluminum plate, preparing a transitional glaze layer, mixing and stirring, spraying the transitional glaze layer, primary firing, spraying a surface glaze layer, secondary firing, cooling and the like. The method is reasonable and feasible, the transitional glaze layer, the aluminum plate and the surface glaze layer are combined closely, a fired product is attractive and elegant, the surface of a print is flat and does not wrinkle, the fired product is firm and durable, and can be stored for a long time, and the technical problems that jet drawing cloth of a decorative picture of an exterior wall of a building easily fades and drops, is shortin service life, and cannot be stored for a long time, the time and cost are wasted if the jet drawing cloth is changed, the cost is increased, an oxidation film of the surface of the aluminum plateis not easily combined to the glaze layer directly, coloring of the glaze layer of the surface is affected, during firing, the aluminum plate is quite easily melted, and cannot be glazed, if the aluminum plate is cooled suddenly after being fired, arched deformation of the surface of the aluminum plate is easily caused, the quality of products is affected, the production benefit of enterprises isalso affected and the like are solved. Compared with the prior art, the manufacturing method of the aluminum plate decorative picture has good market prospect and development space.

Description

technical field [0001] The invention relates to the technical field of metal enamel, in particular to a method for making decorative paintings on aluminum plates. Background technique [0002] In recent years, with the intensification of market competition, many companies have adopted the advertising method of advertising on outdoor billboards, especially near some eye-catching buildings. Or the surface of the iron plate, although it looks beautiful temporarily, there are the following problems: First, the inkjet cloth is exposed to the outside for a long time, and it is easy to fade and fall off, which affects the appearance of the building; second, the life of the inkjet cloth is short and cannot be preserved for a long time. Objects, especially roadside billboards on highways, often need to be replaced in two to three months, which is not only dangerous to operate, but also time-consuming and labor-intensive; third, frequent replacement leads to increased costs, especiall...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that the inkjet cloth in the existing building exterior wall decoration painting is easy to fade and fall off, which affects the appearance of the building. There is a dense oxide film on the surface of the aluminum plate. The oxide film is not easy to be directly combined with the glaze layer, which will affect the subsequent coloring of the glaze layer on the surface. Lowering the temperature will easily lead to arching and deformation of the surface of the aluminum plate, which will affect the quality and affect the product quality and the production efficiency of the enterprise. The surface glaze layer is closely combined, the fired product is beautiful and generous, the surface of the print is smooth and wrinkle-free, durable, and can be preserved for a long time
