Metal rust preventive emulsion and preparation method thereof

Abstract

The invention discloses a metal anti-rust emulsion including the following raw materials: phthaloyl amidoacetic acid alcoholamine salt, acetyl triethyl citrate, tetrabutylammonium acetate, an antifoaming agent, a surfactant, methyl hydroxyethyl cellulose, aqueous resin and water. The invention also provides a preparation method of the metal anti-rust emulsion, and the method comprising the steps of: adding the phthaloyl amidoacetic acid alcoholamine salt, the acetyl triethyl citrate and the tetrabutylammonium acetate into the water, heating and stirring uniformly to prepare a prefabrication material A; adjusting the pH of the aqueous resin to 7.5 to 9, adding the prefabrication material A, then adding the antifoaming agent, the surfactant and the methyl hydroxyethyl cellulose, and uniformly stirring to obtain the metal anti-rust emulsion. The metal anti-rust emulsion is good in film forming property, strong in adhesive force, high in anti-corrosion efficiency, green and environmentally-friendly.

Description

technical field [0001] The invention relates to the field of antirust technology, in particular to a metal antirust emulsion and a preparation method thereof. Background technique [0002] Metal materials are the material basis of human civilization, and metal corrosion that occurs all the time has also caused huge losses to human society. For example, in buildings, equipment, aircraft, aircraft carriers, cables, metal pipes, etc., corrosion will cause irreversible damage and loss to the shape, luster and mechanical properties of the metal, and some may even directly make the product scrapped, resulting in waste of resources and harm safety of human life. [0003] At present, anti-rust water is commonly used for anti-corrosion treatment of metal materials. Anti-rust water is made of water as the basic material, adding water-soluble organic corrosion inhibitors, surfactants, penetrants, etc., but due to the limited water-soluble time of organic matter, Precipitation is pron...

[0003] At present, anti-rust water is commonly used for anti-corrosion treatment of metal materials. Anti-rust water is made of water as the basic material, adding water-soluble organic corrosion inhibitors, surfactants, penetrants, etc., but due to the limited water-soluble time of organic matter, Precipitation is prone to occur during storage, which affects product appearance and performance, and gradually fails to meet people's needs
