Novel environment-friendly anti-corrosion coating used on surface of metal and application of novel environment-friendly anti-corrosion coating

Abstract

The invention relates to a novel environment-friendly anti-corrosion coating used on the surface of a metal and application of the novel environment-friendly anti-corrosion coating, and belongs to the technical field of metal corrosion prevention. The novel environment-friendly anti-corrosion coating used on the surface of the metal consists of the following raw materials in parts by weight: 0.5-3.0 parts of dextran and 0.5-3.0 parts of albumin bovine. The application of the novel environment-friendly anti-corrosion coating used on the surface of the metal is that 0.05-0.30 part by weight of dextran and 0.05-0.30 part by weight of albumin bovine are added into 100 parts by weight of water, and are stirred at the room temperature so as to obtain the anti-corrosion coating; carbon steel is soaked in the anti-corrosion coating for 12-36 hours at the room temperature, and is subsequently and naturally dried for 15-30 hours at the room temperature. The novel environment-friendly anti-corrosion coating used on the surface of the metal is free of toxic substance, green and environment-friendly in the production, storage and use procedures, and is harmless for human bodies; when the mass ratio of dextran to albumin bovine is 2.0:1.3, the anti-corrosion property of the carbon steel can be improved by 60%.

Description

technical field [0001] The invention belongs to the technical field of metal anti-corrosion, and in particular relates to a novel green anti-corrosion coating for metal surfaces and the application of the green anti-corrosion coating. Background technique [0002] Metal materials are damaged by the action of the surrounding medium, which is called metal corrosion. During corrosion, a chemical or electrochemical heterogeneous reaction occurs at the interface of the metal, which turns the metal into an oxidized (ionic) 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 explosion. sex accident. [0003] Metal materials are widely used in people's production and life and are prone to corrosion. Am...
