Water-soluble metal short-term antirust liquid and preparation method thereof

Abstract

The invention discloses a water-soluble metal short-term antirust liquid which is prepared from the following raw materials in parts by weight: 2-3 parts of alkyl polyglucoside, 1-2 parts of an emulsifier OP-10, 2-3 parts of sodium metaborate, 1-2 parts of ascorbic acid, 2-3 parts of butyl hydroxyanisole, 0.5-1.5 parts of urotropine, 1.1-1.7 parts of trioleic acid tallow diamine, 0.5-1 part of silicon nitride, 10-12 parts of acrylonitrile, 5-7 parts of water glass, 1-2 parts of EDTA disodium, 4-5 parts of an auxiliary agent, and 300 parts of water. The antirust liquid can form a thin film on a metal surface, so as to isolate air and prevent oxidation; the thin film is easy to clean up, and can be immediately removed by water washing; the antirust liquid has good oxidation resistance and corrosion inhibition effects, can form the oxidation protective film on the metal surface, and has lasting antirust effect; and the antirust liquid is suitable for short-term rust prevention of hardware, automobile parts and other metal products, and does not affect welding and other performance.

Description

technical field [0001] The invention relates to the technical field of antirust, in particular to a water-soluble metal short-term 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 solvents to dissolve, ...

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
