Problems solved by technology

This kind of color pre-coated steel plate is used as the shell of household appliances without any pollution to the environment, but the surface generally cannot be printed with patterns, and the grade of the shell of household appliances is not high
Moreover, due to the characteristics of the production process and the surface coating of the existing color pre-coated steel plate, there is no suitable printing process to achieve the pattern / pattern effect after surface coating, and the existing paint and ink do not have affinity
[0004] The color laminated steel plate adopts the following structure: the base material is made of cold-rolled sheet, electro-galvanized sheet, hot-dip galvanized sheet, galvanized sheet, etc., with chemical treatment layers on both sides, and the front chemical treatment layer The outer layer of the film is coated with acrylic resin, and there is also a composite film of polyethylene terephthalate and polyvinyl chloride on it, and various printings are performed on the back of the polyethylene terephthalate layer of the composite film However, the polyvinyl chloride layer will be treated as garbage and will produce chlorine and dioxide gas when it is melted, which will pollute the environment, and because the processing materials and processes are relatively complicated, the cost is very high
[0005] Existing colored laminated steel sheets are directly laminated on the surface of the steel sheet after various printings are carried out on the composite film. It is beneficial to environmental protection, and due to the complicated process, the product cost is high
[0012] In summary, the existing technology is applied to the problem that pattern printing cannot be realized on the surface of ordinary colored pre-coated steel sheets for home appliances and architectural decoration, especially gravure printing. In view of this, the present invention is proposed

Embodiment 1

[0044] In this embodiment, the printing process is as follows, a gravure roll 1, the gravure roll 1 is immersed in the printing ink storage tank 6 to continuously coat the ink, the gravure roll 1 after the ink is dipped Use the scraper 2 to scrape off excess ink, and the ink pattern on the gravure roller 1 is transferred to the surface of the printing rubber roller 3, and the printing rubber roller 3 prints the ink pattern on its surface on the steel plate 7, and the other side of the steel plate is set A support roller 4.

Embodiment 2

[0046] In this embodiment, the printing process is as follows, a gravure roll 1, the gravure roll 1 is immersed in the printing ink storage tank 6 to continuously coat the ink, the gravure roll 1 after the ink is dipped Use the scraper 2 to scrape off the excess ink, the ink pattern on the gravure roller 1 is transferred to the surface of the printing rubber roller 3, and the printing rubber roller 3 prints the ink pattern on its surface on the steel plate 7, and the support of the steel plate 7 is on the plane On the support transmission belt 5, on the other side of the printing rubber roller 3, a cleaning roller 9 is arranged, and the cleaning roller 9 is immersed in the washing tank 8 and is continuously cleaned. Another doctor blade 2 is arranged on the printing rubber roller 3 .

[0047] In the steel plate printing process of the present invention, if the ink printing lines are not clear, a cleaning roller can be added at the position of the printing rubber roller.

Abstract

The present invention is printed metal plate and its making process. On the surface of coated steel sheet, patterns are first printed with ink fitting the surface coating of steel sheet and through intaglio offset printing, and high temperature cured paint or UV cured paint is then roller coated to the surface of the patterns. The printed metal plate has high decorating effect. Compared with available technology, the present invention has the advantages of environment friendship and low cost.

Description

technical field [0001] The invention belongs to the field of color printed metal plates used for housings of household appliances, interior and exterior decoration of buildings, etc., and particularly relates to a steel plate suitable for various bending, impacting, stretching and other sheet metal processing after indirect printing with gravure rubber rollers and a manufacturing method thereof. Background technique [0002] At present, colored metal plates used in the market for housings of household appliances and interior and exterior decoration of buildings, such as refrigerator shells, refrigerator side panels, microwave oven shells, air conditioner shells, washing machine shells, etc., generally use colored pre-painted steel plates and colored laminated steel plates. [0003] The color pre-coated steel plate adopts the following structure: the base material is made of steel plates such as cold-rolled plate, electro-galvanized plate, hot-dip galvanized plate, galvanized ...
