Water-based normal-temperature rust-removal rust-proof liquid and preparation method thereof

Abstract

The invention relates to a water-based normal-temperature rust-removal rust-proof liquid, which is prepared from the following active ingredients in parts by weight: 1-2 parts of zinc oxide, 2-3 parts of manganese dioxide, 2-3 parts of citric acid, 22-24 parts of E-12 epoxy resin, 6-8 parts of sodium hexametaphosphate, 1-2 parts of dimethyl formamide, 2-3 parts of catechol, 1-2 parts of sodium dodecyl benzene sulfonate, 13-15 parts of bisphenol A epoxy acrylate, 1-2 parts of disodium edetate dihydrate, 4-5 parts of auxiliaries and 300 parts of water. The rust-proof liquid can fast remove oil and rust at normal temperature, and can be corrosion-resistant and antibacterial, a thin film can be formed on a metal surface by using organic polymer resin and a chelating agent so as to isolate air and achieve the oxidization prevention effect, and the corrosion-inhibition and rust-proof effects are better, the thin film is easy to remove with water, thus being energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of rust prevention, in particular to a water-based room temperature rust removal and rust prevention 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 org...

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
