CORROSION INHIBITOR COMPOSITION FOR STEEL

摘要

Steel anticorrosion and lubricity composition consisting essentially of: (a) a surfactant; (b) at least one neutralized alkyl phosphate in a surfactant:phosphate weight ratio in the range between 10:1 to 1:10, said phosphate having the general formula: (RO)m-P-(O)-(OH)n wherein R is an alkyl group having 4 to 20 carbon atoms; m is 1 or 2, and n is 3 - n; and optionally (c) 5 to 40 weight percent, based on the combined weight of said surfactant and said phosphate, of at least one carboxylic acid which has both a hydrophilic and a hydrophobic portion.
