Corrosion inhibitor

Abstract

A corrosion inhibitor comprises compositions of, by weight part ratio, 10-15 parts of sodium silicate, 5-10 parts of multivariate copolymerization sodium polyacrylate, 2-5 parts of hydroxyl ethidene diphosphonic acid, 4-9 parts of mercaptobenzothiazole, 15-20 parts of benzotriazole, 15-25 parts of sodium tripolyphosphate, 5-15 parts of ethanol, 15-20 parts of hexamethylene tetramine, 4-9 parts of imidazoline, 11-18 parts of mercaptobenzothiazole, 2-7 parts of alkyl alkamine and 3-8 parts of furfural. The corrosion inhibitor is strong in water absorbing quality and pollution-free, has wetting ability, and can reduce the freezing point of water.

Description

technical field [0001] The invention relates to a corrosion inhibitor. Background technique [0002] A corrosion inhibitor is a chemical substance or a mixture of several chemical substances that can prevent or slow down the corrosion of metal surfaces when present in the environment (medium) in an appropriate concentration and form. At present, the corrosion inhibitors used by people 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.; its use is single, and it is only suitable for one medium ;In addition, in addition to delaying metal corrosion, it is not used as a lubricant, softener, humectant, antifreeze and heat transfer agent; corrosion inhibitors are mostly dissolved in various organic solvents, some are...

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.
