Abstract

The invention provides a water-based metal rust inhibitor and a preparation method thereof. The rust inhibitor comprises sorbitan monooleate, inositol hexaphosphate, zinc dihydrogen phosphate, acrylamide, glutamic acid, dinonyl-naphthalenesulfonate, dicyclohexylamine, octadecylamine oleyl sarcosinate, oxidized barium petrotate, sodium ethylenediamine teramethylene phosphonate, 1-hydroxyethylidene, dimethylaminoethyl acrylate, sulfomethylated polyacrylamide, a film forming agent and deionized water. The preparation method comprises the steps of firstly, mixing sorbitan monooleate, inositol hexaphosphate, zinc dihydrogen phosphate and water, and adding octadecylamine oleyl sarcosinate; then, adding acrylamide, glutamic acid, dinonyl-naphthalenesulfonate, dicyclohexylamine and oxidized barium petrotate into the deionized water, and adding 1-hydroxyethylidene; and mixing a mixture I and a mixture II, and adding the left components to obtain the water-based metal rust inhibitor. The rust inhibitor can be attached to the surface of metal, so that the metal has better wear resistance and corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a metal water-based antirust agent and a preparation method thereof. Background technique [0002] The process in which the metal is in contact with the surrounding medium and undergoes a certain reaction with each other and is gradually destroyed is called "metal corrosion". Metal corrosion is a ubiquitous natural phenomenon. It not only damages the metal material itself in terms of shape, color and mechanical properties, but also reduces the quality level of its products, damages precision and sensitivity, affects its use and even scraps it. The loss caused by metal corrosion is very alarming. It is reported that 10% of the steel in the world is corroded. Therefore, preventing metal corrosion is a very important issue. [0003] There are many types of metal corrosion, which can be divided into atmospheric corrosion, high temperature gas, chemical co...
