Green and environment-friendly water-based antirust agent and preparation method thereof

Abstract

The invention discloses a green and environment-friendly water-based antirust agent. The green and environment-friendly water-based antirust agent is characterized in that the water-based antirust agent is prepared from the following raw materials in parts by weight: 0.5-1 part of chitosan, 0.3-0.5 part of citric acid, 0.1-0.2 part of tea polyphenol, 0.5-1 part of polyaspartic acid, 6-8 parts of gelatin, 1-2 parts of sodium citrate, 0.1-0.2 part of cocoalkanoylamido propyl betaine, 8-10 parts of pure acrylic emulsion, 1-2 parts of sodium dihydrogen phosphate, 0.2-0.4 part of polysorbate-80, 0.5-1 part of sodium polyacrylate, 6-8 parts of a modified additive and 30-40 parts of water. The antirust agent disclosed by the invention is good in the film-forming property on metal surfaces, can isolate the metal surface from being in contact with oxygen and water vapor, and the purpose of rust protection is achieved; moreover, the antirust agent is safe, pollution-free, green and environment-friendly, and has good environmental benefits.

Description

technical field [0001] The invention relates to the field of metal treatment, in particular to a green and environment-friendly water-based antirust agent and a preparation method thereof. Background technique [0002] Metal workpieces are prone to rust during production, processing and transportation. Once rusted, it will have a negative impact on the appearance and performance of the finished product. Serious corrosion may even cause the steel to be scrapped. The rusting of steel has caused huge losses to the national economy, so it is necessary to use rust inhibitors to protect metals. Rust inhibitors work by preventing the metal from rusting by forming a thin film on the metal surface. Most of the commonly used antirust agents are oily, and a large amount of organic solvents are used in the process of production and use, causing pollution to the environment. Therefore, the research on water-based antirust agents is of great significance. [0003] Most of the traditiona...

Most of the commonly used antirust agents are oily, and a large amount of organic solvents are used in the process of production and use, causing pollution to the environment. Therefore, the research on water-based antirust agents is of great significance

[0003] Most of the traditional metal water-based rust inhibitors contain nitrite, which has the advantages of low price, good effect, convenient use, and easy removal. However, because nitrite can be converted into carcinogens, its use and discharge have been strictly controlled. limit
