Abstract

The invention discloses a metal water-based rust inhibitor. The metal water-based rust inhibitor is prepared from the following raw materials in parts by weight: citric acid, sorbitan monooleate, phytate, zinc dihydrogen phosphate, acrylamide, glutamic acid, dinonyl naphthalene sulfonate, dicyclohexylamine, oxidized stone grease barium soap, ethylenediamine tetramethylene sodium phosphate, dimethylamino ethyl acrylate, sulfomethylated polyacrylamide, a film forming agent, deionized water, a water-soluble resin, a silane coupling agent, a passivating agent, silica sol, a pH regulator, a surfactant, a plant corrosion inhibitor and zinc sulfate heptahydrate. The metal water-based rust inhibitor can be attached to a surface of the metal to ensure the metal has better antiwear property and antirust property; and the metal water-based rust inhibitor is simple in preparation process, no harm to a human body, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a metal water-based antirust agent. 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 corrosion, seawater corrosion, soil corrosion, ...
