At present, metal plates, especially steel plates and aluminum materials, are used more and more widely. They are used in various home appliance industries such as refrigerator door panels, water heater panels, air-conditioning panels, washing machines, as well as in industrial and civil buildings such as automobiles, kitchen equipment, and anti-theft door panels. However, the metal plate is easily oxidized and corroded during use. Therefore, it is necessary to carry out anti-corrosion and anti-rust treatment, such as spraying paint, etc., but its anti-corrosion and anti-rust ability is still not strong enough, and the paint is easy to scratch and fall off, shortening the The service life of the metal plate is greatly affected and the appearance of the metal plate is seriously affected.

In recent years, in the home appliance industry, film materials have gradually emerged on the surface of metal plates to play a protective role. However, it is a pity that ordinary membrane materials can also cover the unique metallic luster of the metal plate while preventing corrosion and rust, losing the original texture of the metal, and it is even more difficult to appear the stainless steel effect, which greatly reduces the decorative effect of the membrane material. Therefore, there is an urgent need in the market to provide a decorative film material that not only has a protective effect, prevents metal oxidation, but also has a metal wire drawing effect, so as to beautify the appearance of the product and improve the product grade.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further, and this is the preferred embodiment of the utility model.

As shown in Figure 1, the utility model relates to a steel plate with imitation metal wire drawing effect, including a steel plate body and an imitation metal wire drawing film, and the imitation metal wire drawing film includes a base film layer 1, and the lower surface of the base film layer 1 is sequentially arranged There is a drawing layer 2, a first corona layer 31, a pre-coat layer 4, a dielectric layer 5 and a vacuum aluminized layer 6, and the upper surface of the base film layer 1 is provided with a second corona layer 32 and a UV coating layer 7 in sequence. . The lower surface of the vacuum aluminized layer 6 is provided with a protective layer 8, the steel plate body includes a steel plate base 12, the upper surface of the steel plate base 12 is provided with a polishing layer 11, and the upper surface of the polishing layer 11 is provided with a passivation layer 10, An adhesive layer 9 is provided between the vacuum aluminum plating layer 6 and the passivation layer 10 .

The base film layer 1 of this embodiment is an environmentally friendly, high temperature resistant and non-deformable film material, such as a PET film. During production and processing, the lower surface of the base film layer 1 is subjected to metal-like wire-drawing treatment to form a wire-drawing layer 2, so that the base film layer 1 forms a metal-like wire-drawing texture to improve the adhesion of the surface of the base film layer 1 after wire-drawing; The upper and lower surfaces of the film layer 1 are corona-treated respectively to form the second corona layer 32 and the first corona layer 31, which improves the dyne coefficient of the base film surface and strengthens the adhesion of the base film surface; After corona on one side of the wire-drawn base film layer 1, screen roller coating is carried out on the surface with methyl methacrylate paint, and baked to form a pre-coat 4, and the base film is destroyed by the acidic characteristics of methyl methacrylate paint The surface of layer 1 enhances the adhesion on the surface of base film layer 1; on the pre-coat layer 4, an acrylic paint is used for mesh roll coating and baked to form a medium layer 5, which is conducive to improving the adhesion between base film layer 1 and vacuum aluminized layer 6.
