Abstract

The invention relates to a production method of a color coated sheet, which can solve the problems that the existing color coated sheet has high corrosion speed and greatly reduced service life due to the action of harmful gases or salt content in the air in industrial areas or coastal areas. The production method comprises the following steps: firstly, a substrate to be coated is degreased, cleaned, phosphorized and cleaned, and then immersed into an electrophoresis tank as a cathode for electro-coating, with the electrophoresis voltage being 100-350V and time being 1-3 minutes; and after coating, the substrate is cleaned, dried, and sprayed or coated with finish paint, thus obtaining the color coated sheet. The production method has the advantages that: coatings with different film thickness but uniformity can be obtained through the electro-coating, and electrophoresis process parameters are adjusted aiming at different electrophoresis coating varieties so as to obtain corrosion-resistant color coated sheet paint films which are used in different areas and at different positions, thus greatly improving the service life of the color coated sheet, and having good product appearance.

Description

technical field

[0001] The invention relates to a method for producing a color-coated plate by using an electrophoretic coating process. Background technique

[0002] Color-coated plate is a coating product obtained by applying organic materials to thin steel plates. It has light weight, beautiful appearance and good corrosion resistance, and can be directly processed. It is used in the construction industry, shipbuilding industry, vehicle manufacturing industry, and furniture industry. , the electrical industry, etc. provide a new type of raw material, which has played a good role in replacing wood with steel, efficient construction, energy saving, and pollution prevention. The production process of conventional color-coated sheets is: based on cold-rolled steel sheets or galvanized sheets, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), apply paint in a continuous method (roller coating method), after baking and The products made by cooli...
