Rust-proof corrosion inhibitor and preparing method thereof

Abstract

The invention provides a rust-proof corrosion inhibitor and the preparing method thereof. The rust-proof corrosion inhibitor comprises sodium silicate, sodium polyacrylate, mercaptobenzothiazole, benzotriazole, sodium tripolyphosphate, hexamethylenetetramine, imidazoline, mercaptobenzothiazole, alkane amido alcohol, furfural, polyphosphates, ethanol amine, sodium borate and ethyl alcohol. The preparing method comprises the steps of heating sodium silicate, sodium polyacrylate, mercaptobenzothiazole, benzotriazole, sodium tripolyphosphate, hexamethylenetetramine, imidazoline, mercaptobenzothiazole, alkane amido alcohol, furfural, ethanol amine and ethyl alcohol mixed liquor to 50-60 DEG C firstly, then adding polyphosphates and sodium borate, continuing to heating to 85-90 DEG C, conducting heat preservation for 2-3 h, and then obtaining the rust-proof corrosion inhibitor after cooling. The rust-proof corrosion inhibitor can be well compatible with variable materials, rust-proof time is long and can be as long as 4-6 months, adaptability to the copper material and the aluminum material is high, and rust-proof time is prolonged due to the fact that a film can be formed on the surface of metal while corrosion inhibition and rust resistance are realized.

Description

technical field [0001] The invention belongs to the technical field of metal anticorrosion, and in particular relates to an 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 heat tr...

Problems solved by technology

Of course, there are also slow-release agents that use several chemical substances in combination, but their functions and uses cannot cover various metals or multiple media, and they are used as other additives besides corrosion inhibitors.
