Abstract
The invention discloses a pickling corrosion inhibitor using an industrial byproduct. The pickling corrosion inhibitor comprises, by mass, 5-8 parts of a quaternized imidazoline cationic surfactant, 3-6 parts of thiourea, 2-4 parts of hexamethylenetetramine, 5-15 parts of the industrial byproduct organic amine, 2-5 parts of a nonionic surfactant and 30-40 parts of deionized water. The pickling corrosion inhibitor using the industrial byproduct organic amine of a pharmaceutical intermediate 1,8-diazabicyclo[5,4,0]undec-7-ene as a main corrosion inhibitor and thiourea, hexamethylenetetramine and the surfactants as an auxiliary corrosion inhibitor and an acid fog inhibitor is added to a pickling solution according to a mass ratio of the pickling corrosion inhibitor to the pickling solution of 1:10 in order to reduce the metal corrosion rate and inhibit the acid fog effect in the pickling process.
