Emulsion type interprocess antirust liquid and preparation method thereof

Abstract

The invention discloses an emulsion type interprocess antirust liquid, which is prepared from the following raw materials by weight: 1-2 parts of sodium molybdate, 1-2 parts of zinc gluconate, 1-2 parts of sodium benzoate, 12-15 parts of glycerol, 32-35 parts of unsaturated polyester resin, 12-14 parts of bismaleimide resin, 2-3 parts of molybdenum trioxide, 3-4 parts of benzyltriethylammonium bromide, 1-2 parts of sodium laurate, 1-2 parts of EDTA-Na, 4-5 parts of an auxiliary agent and 300 parts of water. The antirust liquid provided by the invention does not contain substances with high toxicity such as sodium nitrite, dichromate and volatile organic amines, or contain phosphate and nitrate components causing eutrophication of water body. The invention uses high molecular resin monomers and the chelating agent to form a thin film on the surface of the metal to isolate the air, and the adhesion antirust agent also has anti-oxidation effect. When being used for rust protection on and steel products, the antirust liquid provided by the invention does not cause iron mold for 20-40 days and can be easily washed with water.

Description

technical field [0001] The invention relates to the field of antirust technology, in particular to an emulsion-type inter-process 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, w...

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
