Deoiling antibacterial antirust liquid and preparation method thereof

Abstract

The invention discloses a deoiling antibacterial antirust liquid which is prepared from the following raw materials in parts by weight: 1-2 parts of dipropylene glycol n-butyl ether, 15-20 parts of ethylene glycol monoethyl ether, 20-24 parts of n-butyl alcohol, 1-2 parts of sodium benzoate, 1-2 parts of benzalkonium chloride, 3-4 parts of polyacrylamide, 4-5 parts of thiodipropionate diester, 7-10 parts of polyvinyl butyral, 6-8 parts of tetrahydrofurfuryl alcohol, 1-2 parts of EDTA disodium, 4-5 parts of an auxiliary agent, and 300 parts of water. Through use of the organic solvent, the antirust liquid can efficiently remove oil; through combined action of high-molecular polymer monomers and the chelating agent, the antirust liquid can form a film on the surface of a metal, thereby isolating air and preventing oxidation; through use of benzalkonium chloride, the antirust liquid can resist bacteria, and enhances the antirust effect; an antirust agent is easy to clean up by water washing; and the antirust liquid has few harmful substances and low cost, is applicable to short and long term rust prevention of metal products and machinery parts, needs no deoiling process, is directly applied, and saves procedures.

Description

technical field [0001] The invention relates to the technical field of antirust, in particular to an oil-removing, antibacterial 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 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
