STEEL CORROSION INHIBITOR AND METHOD FOR OBTAINING THEREOF Russian patent published in 2010 - IPC C23F11/173 

FIELD: metallurgy.

SUBSTANCE: invention is intended for protection of steel constructions and facilities against atmosphere corrosion. Inhibitor contains the following, wt %: carboxymethyl cellulose 0.15-0.5; bentonitic clay 0.5-1.0; water - the rest. In the method, as water-soluble polymer, there used is swollen concentrated water solution of carboxymethyl cellulose with degree of polymerisation of 700-900 with content of polymer of 1.5-5.0 wt %, which is mixed with equal quantity of concentrated swollen water solution of bentonitic clay with clay content of 5-10 wt %; then the obtained mass is mixed till homogeneous composition is obtained, and immediately before it is used, there added is design amount of water till the above specified inhibitor is obtained, an the obtained compound is mixed till it is homogeneous.

EFFECT: application of popular cheap polymer and other cheap non-toxic components, simplifying the method, possibility of obtaining the inhibitor at working station.
