Problems solved by technology

However, on the one hand, due to the thick paint coating, which needs to reach at least tens of microns or even hundreds of microns, the thickness and appearance of the original metal material have been changed; Safety accidents; in addition, with long-term use, the coating is easy to peel off and loses its protective effect on the metal
The commonly used zinc-rich anti-oxidation paint needs to consume a large amount of metal zinc powder, which is costly and wastes zinc resources

Abstract

The invention discloses a metal anti-oxidation treatment method. The method comprises the following steps: 1) preparing a dilute acid solution A and an alkylamine or unsaturated alkylamine solution B; (2) metal to be treated is soaked in the dilute acid solution A to remove an original oxide layer on the surface of the metal, and then distilled water and ethyl alcohol are used for washing the metal; and (3) transferring the metal treated in the step (2) into an alkylamine or unsaturated alkyl amine solution B, reacting at a certain temperature, and finally washing and airing the treated metal. According to the invention, the metal material which is easy to oxidize can be protected, and the oxidation resistance of the modified material is greatly improved.

Description

technical field [0001] The invention relates to the field of anti-oxidation of metal materials, in particular to a treatment method for anti-oxidation of metals. Background technique [0002] The essence of metal oxidation is the phenomenon that metal materials react with air to form oxides after they come into contact with the air medium. In nature, except for a few metals, such as platinum and gold, basically all metals found now will undergo oxidation reactions with oxygen. When the metal is oxidized, a chemical or electrochemical heterogeneous reaction occurs on the interface of the metal, which turns the metal into an oxidized (ion) state. This will significantly reduce the mechanical properties of metal materials such as strength, plasticity, and toughness, destroy the geometry of metal components, increase wear between parts, deteriorate electrical and optical physical properties, shorten the service life of equipment, and even cause disasters such as fire and explos...
