In metal press working. The technical processing method that metal is forced to pass through a die under the action of external force, the cross section area of the metal is compressed, and the required shape and size of the cross section area are obtained is called as a metal wire drawing process, for example, the metal wire drawing process is carried out by using scouring pad, nylon and other materials, and then transparent or semitransparent finish paint is coated to obtain coating wire drawing color-coated plate finished products with different effects, and multiple colors can be realized, so that the coating wire drawing color-coated plate is richer in color and has attractive appearance.

In this embodiment, the second surface opposite to the first surface of the galvanized substrate is provided with the back paint 4, so that the basic anticorrosion performance of the galvanized substrate is high. The thickness of the back lacquer 5 may be 3-20 μm.

The specific zinc-plated base layer comprises a metal substrate 1, wherein two sides of the metal substrate 1 are subjected to zinc plating treatment to obtain a zinc-plated layer 2, and two sides of the zinc-plated layer are subjected to passivation treatment to obtain a passivation layer 3. The galvanized layer becomes thinner continuously after being corroded, which not only damages the appearance of the galvanized layer, but also loses the protective capability of the metal base layer. The corrosion resistance of the zinc coating can be remarkably improved if the zinc coating is passivated in a chromic acid solution with a certain composition to form a chromate film with a fine structure and high corrosion resistance, namely a passivation film on the surface of the zinc coating). The chromate passive film is firmly adhered to the surface of the galvanized layer, so that the galvanized layer is isolated from the atmosphere on one hand, and the corrosion of harmful gases in the atmosphere to the galvanized layer is slowed down to play a good mechanical protection role; on the other hand, once the passivation film of the zinc coating is locally damaged or the cracks are corroded by the atmosphere, the chromium in the passivation film can passivate the zinc coating again, the passivation film is automatically repaired, and meanwhile, the chromate serving as an anode inhibitor for corroding the primary battery hinders the anode reaction, so that the corrosion of the zinc coating is greatly slowed down.
