Water-based metal surface antirust solution and preparation method thereof

Abstract

The invention discloses a water-based metal surface antirust solution prepared from the following raw materials in parts by weight: 18-23 parts of alkyd resin, 1-2 parts of sodium benzoate, 1-2 parts of ethylenediamine tetraacetic acid, 5-6 parts of polyethylene glycol, 1-2 parts of urea, 6-9 parts of glycerol, 1.9-2.7 parts of polyisobutylene, 2.1-2.9 parts of 2-aminoethyl heptadecenyl imidazoline, 1-2 parts of methacrylic acid dimethyl amino ethyl ester, 1-2 parts of allyl glycidyl ether, 1-2 parts of EDTA (ethylene diamine tetraacetic acid) disodium, 4-5 parts of an auxiliary agent and 300 parts of water. According to the water-based metal surface antirust solution disclosed by the invention, resin and a chelating agent are used, so that a relatively firm film can be formed on the surface of a metal to play roles in isolating air and moisture and fixing an antirust substance to ensure that the metal has a reliable and long-time antirust effect, the corrosion resistance of the surface of the metal can be improved, and acid mist is not generated; the water-based metal surface antirust solution is safe and reliable and is easy in operation.

Description

technical field [0001] The invention relates to the technical field of rust prevention, in particular to a water-based metal surface rust preventive liquid and a preparation method thereof. Background technique [0002] Rust prevention on metal surfaces is an important subject in industrial production. Traditional antirust liquids and antirust oils have both advantages and disadvantages. Ordinary anti-rust water contains a large amount of sodium nitrite, which is carcinogenic and is not conducive to environmental protection and human health. However, the use of humectants to prolong the life of anti-rust water brings the disadvantages of sticking hands and dust, and cannot prevent rust for a long time; Although the general dura-film anti-rust oil is suitable for long-term anti-rust, and the film is transparent and beautiful, there are few types of colorless and transparent resins, which are unstable and easy to oxidize and change color. They also need organic solvents to d...

Problems solved by technology

Ordinary anti-rust water contains a large amount of sodium nitrite, which is carcinogenic and is not conducive to environmental protection and human health. However, the use of humectants to prolong the life of anti-rust water brings the disadvantages of sticking hands and dust, and cannot prevent rust for a long time; Although the general dura-film anti-rust oil is suitable for long-term anti-rust, and the film is transparent and beautiful, there are few types of colorless and transparent resins, which are unstable and easy to oxidize and change color. They also need organic solvents to dissolve, which brings the danger of flammability and explosion. It is not conducive to environmental protection and health; the general anti-rust oil uses mineral oil, which is difficult to degrade, and it will also cause the problem of difficult degreasing when used for short-term anti-rust
