Abstract

The invention relates to a preparation method of an imitated-metal enameled steel sheet. The prepared enameled steel sheet has the advantages of good mechanical properties, good heat resistance, excellent chemical stability, clean and gorgeous appearance, and easy cleaning and decontamination. The enameled steel sheet is suitable to be used in decorative enamel of building interior and exterior wall decorations and decorative enamel of public places such as tunnels and subways. The enameled steel sheet has good imitated metal effect. A production process of the enameled steel sheet comprises the steps that: a suspending agent, water, sodium fluoroborate, urea, and potassium fluorosilicate are added into a transparent base glaze; ball milling is carried out, such that a glaze slurry is obtained; imitated-metal powder is added into the glaze slurry, and the mixture is well mixed, such that an imitated-metal enamel glaze is obtained; the imitated-metal enamel glaze is sprayed on a biscuit by using a spray gun; and the material is fired under a temperature of 800-860 DEG C, such that the imitated-metal enameled steel sheet is obtained.

Description

technical field [0001] The invention relates to a method for preparing a metal-like enamel steel plate. The prepared metal-like enamel steel plate has good mechanical properties, good heat resistance, excellent chemical stability, clean and gorgeous appearance, and is easy to clean and decontaminate. It is suitable for decoration of interior and exterior walls of buildings and decoration enamel of public places such as tunnels and subways. Background technique [0002] Enamel-coated products are also called post-coated products, which are products that provide functions such as corrosion resistance, chemical resistance, and weathering resistance by forming an enamel layer on the surface of a steel plate substrate, and improve the life of the steel plate. Compared with pre-coated products, enamel-coated products have disadvantages such as high manufacturing cost, but they have excellent quality in terms of hardness, weather resistance, washability, heat resistance and non-com...
