Abstract

The invention provides metal antirust inhibitor and a preparing method thereof. The antirust inhibitor comprises sodium silicate, sodium polyacrylate, mercaptobenzothiazole, benzotriazole, sodium tripolyphosphate, hexamethylenetetramine, imidazoline, alkyl amino alcohol, furfural, polyphosphates, cholamine, sodium borate and ethyl alcohol. The preparing method includes the steps that firstly the sodium silicate, the sodium polyacrylate, the mercaptobenzothiazole, the benzotriazole, the sodium tripolyphosphate, the hexamethylenetetramine, the imidazoline, the alkyl amino alcohol, the furfural, the cholamine and the ethyl alcohol are mixed and heated to be 50 DEG C-60 DEG C, and then the polyphosphates and the sodium borate are added; and the mixture is continuously heated to be 85 DEG C-90 DEG C, heat preservation is conducted on the mixture for 2-3 hours, and then the metal antirust inhibitor is obtained after being cooled naturally. The antirust inhibitor is good in compatibility with all materials, and the antirust time is long and can reach 4-6 hours; and adaptability to copper and aluminum is good, and slow-release rust resistance is achieved while a membrane is formed on the surface of metal, so that the antirust time is prolonged.

Description

technical field [0001] The invention belongs to the technical field of metal anticorrosion, and in particular relates to a metal antirust and corrosion inhibitor and a preparation method thereof. Background technique [0002] A corrosion inhibitor is a chemical substance or mixture of several chemicals that prevents or slows down the corrosion of metal surfaces when present in the environment in appropriate concentrations and forms. At present, the corrosion inhibitors used include inorganic compound corrosion inhibitors and organic compound corrosion inhibitors. Most of the known corrosion inhibitors have a single function and can only be used to prevent or slow down the corrosion of a single metal, that is, only play a major role in one of the metals such as iron, steel, copper, etc., and have a single purpose and are only suitable for one medium; In addition, in addition to delaying metal corrosion, it cannot be used as a lubricant, softener, humectant, antifreeze or hea...
