CORROSION INHIBITOR AND METHOD OF INHIBITING CORROSION

摘要

A corrosion inhibitor which combines a film-forming function with a neutralizing function, can be stably stored for long even in a high-temperature environment, and can be easily produced in one batch. The corrosion inhibitor comprises ingredients respectively in the following groups (A) to (C): (A) C<SUB>10-22</SUB> aliphatic amines; (B) surfactants comprising a polyethylene glycol/fatty acid ester; and (C) one or more water-soluble amines selected from the group consisting of 2-amino-2-methylpropanol, morpholine, and monoisopropanolamine.
