Problems solved by technology

Because this method needs to print the pattern on the film first and then stick the film, the workmanship is poor, the cost is also high, and the gas harmful to the environment will be generated during the subsequent processing.
Another method is transfer printing, that is, the pattern is transferred to paper or film by offset printing or screen printing, and the patterned side of the paper or film is pasted on the steel plate undercoat, and the pattern is transferred under high temperature or high pressure. Printed on the coating on the surface of the steel plate, the surface pattern of the film or paper used as the medium will become light after the transfer, and the paper or film will only serve as the transfer medium, which also has the problems of complicated process and high production cost
Another way of thinking is to add additives to improve adhesion in primer coatings or inks, and develop new coatings or inks, but this way of adding additives will increase the cost

Embodiment 1

[0020] The production method of printed panels for home appliances is explained in detail as follows:

[0021] (1) Substrate pretreatment: use galvanized steel sheet (or aluminum-zinc-silicon-coated steel sheet) with a thickness greater than 0.4mm as the substrate, and the coating content is 5g-150g / m on one side 2 ; Passivate the surface of chromate to enhance the adhesion between the paint and the substrate, and then coat the primer with a paint that does not contain a slip agent on the surface of the substrate, and dry it to form a primer with a dry film thickness of 10-50 μm. Paint layer; the paint is composed of polyester resin, amino resin, toner, catalyst, acrylate leveling agent and thinner, the amount of each component is the conventional amount of the current paint, the difference is that it does not contain slip agent.

[0022] (2) Pattern printing: use screen printing equipment (or offset printing equipment) to print patterns on the block substrate treated with pri...

Embodiment 2

[0026] The difference from Example 1 is that in step (1), a brushed printing process is used on the surface of the substrate, and a printing primer layer is formed by brushed printing with a metal paint that does not contain a slip agent.

[0027] The specific scheme is shown in Table 1:

Abstract

The invention discloses a household appliance printing panel producing method and a household appliance printing panel produced thereby. The method sequentially comprises the following steps of: (1) pretreating a substrate, namely taking a galvanized steel plate or an aluminum-zinc plated silicon steel plate as the substrate, coating a chromate passivating film on the surface of the substrate, forming a base coating layer on the surface by using a coating which does not contain slip agents, and drying; (2) printing a pattern, namely printing the pattern on a blocky substrate subjected to basecoating treatment by using screen printing equipment or offset printing equipment, and drying; and (3) performing varnish finishing, namely coating a transparent polyester coating or an ultraviolet light curing transparent coating on the surface of the pattern, and curing to form a varnish finishing layer of which the dry film thickness is 10 to 100 micrometers. The panel produced by the method has a distinct pattern, a product has a high machining property, and the production method meets the requirement of machining of the household appliance printing panel.

Description

technical field [0001] The invention relates to a production method of a printed home appliance panel to meet the decoration and weather resistance requirements of high-end home appliances for the panel. Background technique [0002] It turns out that the panels of household appliances on the market have only one color (usually called white goods), and the appearance of this kind of white goods is relatively monotonous. In addition, the original steel panels of home appliances, due to the limitation of coating materials and the influence of coating technology, often have the phenomenon of peeling off of the top coat and rusting of the panels after a period of use, which also affects the appearance of the panels. [0003] With the improvement of living standards, people's aesthetic requirements for the appearance of home appliances are also increasing. Not only are home appliances required to be novel in shape, rich in patterns and colors, but also required to have an appeara...
