ANTICORROSIVE COMPOSITION FOR CORROSIVE PREVENTION OF STEEL AND REINFORCED CONCRETE SURFACES Russian patent published in 2008 - IPC C09D5/08 

FIELD: inorganic chemistry.

SUBSTANCE: anticorrosive composition is applied for corrosive prevention of reinforced concrete and metal surfaces of structures and equipment in high humidity and sulphur dioxide, hydrogen sulphide, chlorine, ammonia. Anticorrosive composition contains industrial lignosulphonates, tall pitch, colophony, pigment-aluminium powder PAP-1, reducing agent - titanium dioxide, zinc phosphate, zinc oxide, hardener - polyethylenepolyamine, modifying agent - hexamethylenetetramine, providing high water resistance. To provide rheological properties composition contains acryloyltrimethylamidopropylammonium chloride in amount 0.02 weight fractions 0.02. Technical result is improved light resistance, reduced dryout period and widen range of colours of protective coating.

EFFECT: production of anticorrosive coating with improved protective properties.
