Abstract

The invention discloses a metal plate, a building and a preparation method of the metal plate, and relates to the technical field of metal material treatment. The service life of the metal plate is prolonged. The preparation method of the metal plate comprises the steps that corrosion-resistant elements including Cu, P, Cr, Si, Ni and Mo are added into a weather-resistant steel substrate, and a compact and stable rust layer can be formed on the surface of the weather-resistant steel substrate in the using process; the upper surface and the lower surface of the weather-resistant steel substrate are subjected to passivation treatment through passivation liquid, and passivation layers are formed on the surface of the weather-resistant steel substrate; and the faces, deviating from the weather-resistant steel substrate, of the two passivation layers are subjected to fingerprint-resistant agent treatment, and fingerprint-resistant layers are formed, wherein the passivation liquid contains an inorganic salt compound and a copper corrosion inhibitor at the same time. The metal plate and the preparation method thereof are used for building manufacturing.

Description

technical field [0001] The invention relates to the technical field of metal material processing, in particular to a metal plate, a building and a method for preparing the metal plate. Background technique [0002] An existing metal plate used on metal roofs or walls is mainly galvanized plate, that is, galvanized on the surface of the carbon steel substrate, and the zinc layer can be used as a sacrificial anode to protect the carbon steel substrate, avoiding the carbon steel substrate in a short period of time. Corrosion occurs within a short period of time, and galvanized sheets are the first choice for roofs and walls of light steel structures in the current construction industry. [0003] However, the main problem of galvanized sheet is that the coating is consumed quickly, and the carbon steel substrate after the coating is completely consumed is easily corroded quickly, resulting in a short service life. Contents of the invention [0004] The invention provides a me...
