Coating process of multi-color plate

Abstract

The invention relates to the technical field of color plate coating, and discloses a coating process of a multi-color plate. The coating process comprises the following steps of (S1) pretreatment, (S2) roller coating of a primer layer, (S3) roller coating of a middle coating, (S4) roller coating of a finish paint layer, and (S5) final treatment, wherein the coating process of the finish paint layer comprises the steps of (a) coloring for the first time: coating first paint to the surface of a color plate, and then drying; (b) coloring for the second time: coating second paint to the surface ofthe color plate, and then drying; and (c) coloring for many times: coating nth paint to the surface of the color plate, and then drying. The step (S4) relates to a plurality of roller coaters, coating rollers which are used for transferring the paint to the color plate are respectively arranged on each roller coater, the coating rollers comprise coating areas and sunken areas, the coating areas are abutted with the color plate, different coating areas are different from each other, and the sum of the widths of all of the coating areas is equal to the width of the color plate. According to thecoating process, roller coating of different colors is performed in different areas of the color plate by utilizing the plurality of roller coaters, so that the processing of the multi-color plate isrealized, the sense of art and applicability of the color plate are increased, and the diversified customer requirements are met.

Description

technical field [0001] The invention relates to the technical field of color plate coating, in particular to a multi-color plate coating process. Background technique [0002] In the field of home appliances, in order to improve the decorative effect, decorative steel plates are usually added to home appliances; nowadays, with the development of the times, decorative steel plates are becoming more and more diversified, and colors are usually painted on the decorative steel plates to form colored steel plates, referred to as Choi board. Generally, the surface of the color plate is coated with three layers of paint, forming a primer layer, a middle coat layer and a top coat layer, wherein the choice of the color of the top coat layer determines the color of the color plate. [0003] Among the many processing techniques of color-coated sheets, the roller coating method is the most widely used process method. Roller coating is to apply glue and other materials on the surface of...

AI Technical Summary

Problems solved by technology

However, the above-mentioned roller coating mechanism and the existing roller coating machine generally can only coat a single color, which cannot meet the diverse needs of today's customers.

Modern technology will spray paint and other treatments after the color plate is processed to realize the multi-color of the color plate. This process needs more manpower, material resources and time, and the product produced has a short service life; while the multi-color formed by roller coating Plates have higher production efficiency and longer service life, and their economic value is much greater than that of single-color plates
