Surface treatment method of metal material

Abstract

The invention relates to the technical field of metal surface treatment, and discloses a surface treatment method of a metal material. The method comprises the following steps: S1, cleaning and decontamination; S2, drying treatment: soaking a textured metal part material in water for cleaning treatment, and then conducting drying at the temperature of 37 DEG C; and S3, coating treatment: putting the metal material into a treating agent solution to be soaked for 30-50 min, and then the taking out and drying the metal material, wherein the treating agent solution comprises the following components: 20-50 g / L of organic active matter, 5-20 g / L of silicate of alkali metal and 2-20 g / L of aluminate of the alkali metal. According to the surface treatment method of the metal material, it is guaranteed that the metal surface treatment method does not contain heavy metal harmful ingredients so that the metal surface has excellent self-adjusting and self-repairing anti-corrosion performance andgood adhesive performance of organic coating, waste water is avoided, the method is non-toxic, harmless, and efficient at a normal temperature, the operation is simple, the cost is lower, and the diffusion of early-stage corrosion products is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a method for surface treatment of metal materials. Background technique [0002] Surface treatment is a method of artificially forming a surface layer on the surface of a base material with mechanical, physical and chemical properties different from that of the base. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. For metal castings, our more commonly used surface treatment methods are mechanical grinding, chemical treatment, surface heat treatment, surface spraying, and surface treatment is to clean, sweep, deburr, degrease, and descale the surface of metal parts. [0003] Surface treatment belongs to the oldest technology. Since there are human beings on the earth, surface treatment is the earliest technology mastered by human beings. The life of primitiv...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a metal material surface treatment method, which ensures that the metal surface treatment method does not contain harmful heavy metal components, so that the metal surface has excellent self-regulating self-repairing anti-corrosion performance, good organic coating Adhesive performance, at the same time, it has the advantages of no waste water, non-toxic, harmless, high efficiency at room temperature, easy operation, stable performance, lower cost, and effectively prevents the diffusion of early corrosion products. There are certain defects in the way of material surface treatment. During the process of metal surface treatment, it is impossible to get rid of heavy metal harmful substances, and it cannot better ensure that the metal surface has excellent self-regulating, self-repairing and anti-corrosion properties. At the same time, wastewater will be generated during the surface treatment process. , causing toxic and harmful damage to the environment, and the efficiency is relatively low, the performance is unstable, and the cost is relatively high
