Embodiment Construction

[0031] The technical solution of the present invention will be described in detail below through specific examples, and these examples are only used to explain and illustrate the present invention and should not be construed as limiting the present invention.

[0032] A metal surface anticorrosion and color-fixing agent, which consists of 2-mercaptobenzimidazole MBI, 2-mercaptobenzoxazole MBO, benzotriazole BTA, imidazole derivatives, polyacrylic resin, polyethylene wax, lubricant And surfactant, wherein polyethylene wax accounts for 3-5% of total weight. In weight percentage, the ratio of 2-mercaptobenzimidazole MBI: 2-mercaptobenzoxazole MBO: benzotriazole BTA: imidazole derivative is 2:1:1:1. The lubricant is one or a combination of stearic acid, butyl stearate or oleamide.

[0033] The imidazole derivative structural formula is as follows:

[0034]

[0035] where: R 2 , R 3 , R 4 and R 5 = H or alkyl; R 1 and R 6 =H alkyl or alkenyl; X = H 3 NOOCR 7 ; 7 = alk...

Abstract

The invention relate to a surface corrosion-preventing and color-fixing agent for metal, a preparation method and the application. The surface corrosion-preventing and color-fixing agent comprises 2-mercapto benzimidazole MBI, 2-mercapto benzoxazole MBO, benzotriazole BTA, imidazole derivatives, polyacrylic resin, polyethylene wax, a lubricating agent and a surface active agent. The weight ratio of the 2-mercapto benzimidazole MBI to the 2-mercapto benzoxazole MBO, the benzotriazole BTA, and the imidazole derivatives is 2:1:1:1. According to the surface corrosion-preventing and color-fixing agent for metal, the preparation method and the application, by using the imidazole derivatives, the surface corrosion-preventing and color-fixing agent can effectively prevent color changing and color fading of the surface of aluminum alloy and can also protect non-ferrous metal against corrosion and solve the problem that the benzotriazole cannot be used for corrosion prevention in an acid environment, and thus the surface corrosion-preventing and color-fixing agent can be used for protecting aluminum alloy against corrosion in all environments.

Description

technical field [0001] The invention belongs to the field of anti-corrosion agents and anti-discoloration, in particular to an anti-corrosion and color-fixing agent for aluminum alloy surfaces, a preparation method and application. Background technique [0002] Equipment and parts of aluminum and its alloys are widely used in various sectors of the national economy, especially in the chemical industry and petrochemical industry. are also increasingly valued. [0003] The corrosion of aluminum alloys under various environmental effects has spread to all sectors of the national economy, causing huge losses, and has great significance for the research of metal protection. Among various metal corrosion protection technologies, corrosion inhibitor technology has become one of the most effective and commonly used methods due to its simple process and strong applicability. However, the corrosion inhibitor technology has obvious limitations. In the liquid phase medium where the co...
