Water-based inter-process environment-friendly antirust liquid and preparation method thereof

Abstract

The invention discloses a water-based inter-process environment-friendly antirust liquid which is prepared from the following raw materials in parts by weight: 2-3 parts of potassium silicate, 1-2 parts of sodium metasilicate, 1-2 parts of sodium benzoate, 6-9 parts of dicyclopentadiene acrylate, 50-60 parts of epoxy acrylate, 2-3 parts of rosin-polythylene oxide ester, 1-2 parts of triphenyl ethyl phenol polyoxyethylene ether, 1-2 parts of EDTA disodium, 4-5 parts of an auxiliary agent, and 300 parts of water. With use of the high-molecular resin and the chelating agent, a thin film can be formed on a metal surface, plays roles in isolating air and preventing oxidation, allows an antirust agent not to easily fall off, has the antioxidant function, improves the corrosion inhibition effect, is easy to clean up, and can be immediately removed by water washing; and the environment-friendly antirust liquid has small surface tension force to metals, is easy to coat, contains no sodium nitrite and other cancerogenic substances, has no volatile substances, has little harm to worker bodies, and is an ideal product for inter-process short-term rust prevention.

Description

technical field [0001] The invention relates to the field of antirust technology, in particular to a water-based inter-process environment-friendly antirust 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 solve...

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
