Изобретение относится к защите металлов от коррозии в соляной и серной кислотах, и может быть применено при травлении металлов в машиностроении и других отраслях производства. Повышение степени защиты от коррозии стали, титана, цинка и латуни и увеличение степени защиты стали от наводороживания достигается использованием в качестве продукта конденсации амина и альдегида N-(3-окси-4-метоксибензалиден)-N- (3'-нитро-6- пиридил)-сульфаниламида 15,1 - 24,0 мас.% и дополнительным содержанием в ингибиторе, мас.%: 6-бутил-N-метилхинолиний иодида 32,9 - 36,0; 5-окситетразола 12,0 - 16,4 и уротропина 28,0 - 35,6.The invention relates to the protection of metals from corrosion in hydrochloric and sulfuric acids, and can be used for pickling metals in mechanical engineering and other industries. An increase in the degree of protection against corrosion of steel, titanium, zinc and brass and an increase in the degree of protection of steel against hydrogenation is achieved by using the condensation product of amine and aldehyde N- (3-hydroxy-4-methoxybenzalidene) -N- (3'-nitro-6- pyridyl) sulfanilamide 15.1 - 24.0 wt.% and an additional content in the inhibitor, wt.%: 6-butyl-N-methylquinolinium iodide 32.9 - 36.0; 5-hydroxytetrazole 12.0 - 16.4 and urotropine 28.0 - 35.6.
