Problems solved by technology

[0004] At present, the imitation stainless steel wire drawing sheets used for home appliance panels include PET / Al / PVC composite steel sheets, PET printed wire drawing composite steel sheets and PET real wire drawing composite steel sheets. To achieve the effect of imitating stainless steel, the production cost of the film is relatively high, and the lamination process is relatively complicated. Therefore, the wide production and application of the product are restricted.

Abstract

The invention relates to a metal wiredrawing composite steel plate and a preparation method thereof. A base material of the metal wiredrawing composite steel plate is a hot galvanizing steel plate or an electro-galvanizing steel plate, a straight grain wiredrawing structure is formed on the front side of the base material through wiredrawing by using a metal surface wiredrawing machine, and a transparent fingerprint-resistant paint layer is formed on the straight grain wiredrawing structure through roller coating. During manufacturing, the method comprises the following steps of: performing wiredrawing process treatment on the front side of the base material by using the metal surface wiredrawing machine; performing degreasing cleaning on the base material subjected to the wiredrawing process treatment to remove oil stains on the surface; performing surface passivation in a sprinkling mode after the degreasing cleaning to form colorless paint bottom passive films on the front side and the back side of the base material, and drying in a drying oven; painting a back paint on the back side of the base material through roller coating at normal temperature after the passivation, and drying in the drying oven; painting a transparent fingerprint-resistant paint on the front side of the base material which is subjected to wiredrawing, degreasing cleaning and passivation; and coating a protective film on the surface of the transparent fingerprint-resistant paint layer. By directly treating the hot galvanizing steel plate or electro-galvanizing steel plate by using a wiredrawing process, and coating a transparent paint layer on the hot galvanizing steel plate or electro-galvanizing steel plate, an appearance effect of imitation stainless steel is achieved.

Description

technical field [0001] The invention relates to a metal composite steel plate, in particular to a metal wire drawing composite steel plate and a preparation method thereof. Background technique [0002] Steel plates are widely used in industry and life, such as automobiles, refrigerators, washing machines, high-end furniture, cabinet equipment, industrial and civil buildings and other fields. The general steel plate can only be used as a final product after being coated with a protective layer or a decorative layer on its surface, mostly after it is made into a product or a semi-finished product, so it brings a lot of inconvenience to the manufacturer and manufacturer. [0003] PET / PVC composite steel plate is a newly developed product in the mid-1990s, which has good properties such as moisture resistance, corrosion resistance, and durability. The color laminated steel plate composited with PET / PVC composite film and steel plate has beautiful appearance, surface decoration...
