THE COMBINED INHIBITOR FOR PROTECTION OF THE METALS AGAINST THE ATMOSPHERIC CORROSION Russian patent published in 2007 - IPC C23F11/00 

FIELD: chemical industry; metallurgy industry, other industries; production of the combined inhibitors for protection of the metals against corrosion.

SUBSTANCE: the invention is pertaining to the field of protection of the metals against the atmospheric corrosion by means of the inhibitor and may be used for the long-time conservation of the metalwares and the products made out of the ferrous metals. The inhibitor contains (in mass %): the product of condensation of the boric acid with diethanolamine and the vegetable oil at their molar ratio 0f 1:3:(0.5-0.7) accordingly- 5-6, the soap stock of the vegetable oil or the oleic acid - 10-15 and the mineral oil - up to 100. The technical result of the invention is - extension of the set of the domestic inhibitors for treatment of the atmospheric corrosion, the increased corrosion resistance of the products made out of the ferrous metals, including - the alloyed steels, and salvaging of the wastes of the vegetable oils production.

EFFECT: the invention ensures the extended list of the domestic inhibitors used for treatment of the atmospheric corrosion effect, the increased corrosion resistance of the products made out of the ferrous metals including the alloyed steels, and salvaging of the wastes of the vegetable oils production.
