Description

Plate and manufacturing method thereof

Technical Field

The invention relates to the technical field of household appliances and electronic equipment, in particular to a plate and a manufacturing method thereof.

Background

Both home appliances and portable electronic devices require a metal material or a hard plastic material as a material of an exterior member. With the increase of the consumption level, the demands of consumers on household appliances and electronic products not only pay attention to the quality of the household appliances but also pay more attention to the appearance, texture and touch of external components of the products.

In order to meet the pursuit of people on the beauty of the shell, the surface of the shell is designed with grains with different forms. However, to form the desired texture on the surface of the plate, the plate is usually etched or painted or transferred by using a chemical solvent.

Etching refers to removing the protective film of the area to be etched after exposure plate making and development, and contacting with a chemical solvent during etching to achieve the effect of dissolving and corroding and form concave-convex lines. The etching process flow is as follows: cleaning, drying, film pasting or walking, drying, exposure, developing, drying, etching and film removing, and therefore, the process of etching by using a chemical solvent is complex and highly polluted.

The paint is not firmly combined on the surface of the plate due to the limitation of the paint spraying and transfer printing of the plate, particularly the property of the metal material, and the product with the paint stably combined on the surface of the plate is not easy to produce.

Hereinafter, a detailed description will be given of a specific embodiment of the present invention.

Fig. 4 is a schematic cross-sectional structure diagram of the plate of the present invention, and the specific manufacturing process is as follows:

in the process of processing, because the surface of the support body 100 has different adhesive force according to different requirements of products, the support body 100 is firstly subjected to pretreatment such as degreasing, deoiling, baking and the like before transparent solution coating, printing and dyeing, so that the influence of impurities on the surface on the adhesive force of the support body is avoided, and a layer of metal oxide film is formed on the surface of the support body, so that the oxidation of the support body is avoided.

The first adhesive layer 200 may be formed by coating a transparent solution on the support 100, i.e. by coating or calendaring the surface of the support 100 to form a layer of transparent material, wherein the material may be made of acrylic resin, acrylic amino resin, alkyd resin, polyol resin or epoxy resin, or may be made of vinyl chloride resin, phenolic resin, polyurethane resin, or may be a colorless transparent graphite material, and the material has good gloss, stability, wear resistance, flexibility, heat resistance, etc. after leveling, drying, calendaring, curing, a thin and uniform transparent bright layer, i.e. the first adhesive layer 200, is formed on the surface of the support 100, thereby improving the surface smoothness, appearance effect, and usability, and being beneficial to enhancing the adhesion between interlayer.

A coating process is applied to the first adhesive layer 200 to form the first structural layer 101, i.e., a printed or dyed layer or both. For example, a pattern or a character can be expressed on the support by printing the support partially or entirely with ink by a screen printing method. The first structural layer 101 is then dyed to form a colored layer 300 thereon, and the surface of the support 100 can be colored by various methods such as electrophoresis, printing, spraying, roll coating, etc., so as to form different color effects on the support locally or entirely.

The second adhesive layer 400 is formed by performing a floating coat process on the first structural layer 101, and since the subsequent imprinting process is required, but a bonding layer process needs to be added for performing a better subsequent imprinting process, a coating process, i.e., a transparent solution coating process, needs to be performed on the coloring layer 300 after the dyeing process, so as to form the second adhesive layer 400, thereby preventing the plate from being damaged by the subsequent direct imprinting. The coating method is the same as that of the first adhesive layer 200 and the material.

After the steps of pretreatment of the support 100, primary application of the transparent solution, printing, dyeing, and secondary application of the transparent solution, the first adhesive layer 200, the first structural layer 101, the colored layer 300, and the second adhesive layer 400 are sequentially formed on the support 100, and these four structural layers are collectively referred to as a decorative layer.

As shown in fig. 6, after the solidification of the first structural layer is confirmed, the support body 100 may be subjected to a press process, and the outer shape of the support body 100 may be finished by the press process, so that the support body 100 may be changed from a planar workpiece to a three-dimensional workpiece. The support body 100 after stamping is bent, the bent part is easy to deform or break when the support body is bent for punching, and the bent part is drilled for cutting to form a notch after drilling and cutting.

If the support is made of metal, the electrophoresis treatment can be directly performed in the drilled notch 107, if the plate is made of non-metal material, for example, the support is made of plastic, wood, glass, etc., a layer of metal material is sputtered in the drilled notch 107, then the electrophoresis treatment is performed in the notch 107, the electrophoresis treatment is performed by electrically coloring the coating with positive or negative ions on the metal surface with direct current, then washing, drying, etc. the coating is firmly attached to the highlight drilled notch 107, the plate is colored by using the electrophoresis electro-technology, the color layer is tightly adsorbed at the highlight drilled notch 107, and the electrophoresis electro-coloring layer 102 is formed.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
