Emulsion-type derusting antirust liquid and preparation method thereof

Abstract

The invention discloses an emulsion-type derusting antirust liquid which is prepared from the following raw materials in parts by weight: 2-3 parts of potassium dihydrogen phosphate, 10-12 parts of isopropanol, 1-2 parts of zinc oxide, 1-2 parts of thiourea, 4-6 parts of polyisobutene, 1-2 parts of sodium dodecyl benzene sulfonate, 9-12 parts of inositol hexaphosphate, 10-12 parts of dipentaerythritol hexaacrylate, 1-2 parts of a silane coupling agent KH560, 1-2 parts of EDTA disodium, 4-5 parts of an auxiliary agent, and 300 parts of water. The derusting antirust liquid can strongly remove rust on the surface of a metal, at the same time, because of containing resin and the chelating agent, the derusting antirust liquid can form a thin film on the surface of the metal, thereby playing a role of isolating air; besides, because of the resin having an anti-oxidation effect and in addition of containing an antirust agent, the derusting antirust liquid has quite excellent antirust effect; and the antirust film can be immediately removed by water washing, thereby saving manpower.

Description

technical field [0001] The invention relates to the technical field of rust prevention, in particular to an emulsion type rust removal and 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 di...

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
