A kind of water-based emulsion antirust liquid and preparation method thereof

Abstract

The invention discloses a water-based emulsion-type antirust liquid and a preparation method thereof. The water-based emulsion-type antirust liquid is prepared from 12-15 parts by weight of urethane acrylate, 4-5 parts by weight of dodecenylsuccinic acid, 1-2 parts by weight of monoethanolamine, 0.9-1.4 parts by weight of sodium molybdate, 1.5-3 parts by weight of polyoxyethylene octylphenol ether, 1-2 parts by weight of hydroquinone, 3-4 parts by weight of ditetradecane alcohol ester, 1-2 parts by weight of ethylenediaminetetraacetic acid disodium salt, 4-5 parts by weight of an assistant and 300 parts by weight of water. The polymer monomer forms a stable emulsion under the action of a chelating agent and a nonionic surfactant and the emulsion forms a film on the metal surface, does not fall off easily, resists oxidation, is not polluted easily and can be cleaned easily. The water-based emulsion-type antirust liquid contains less harmful substances, has a low cost and is suitable for long / short-period rust prevention of metal products and machinery parts.

Description

technical field [0001] The invention relates to the field of antirust technology, in particular to a water-based emulsion type 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, which ...

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
