TIXOTROPIC MATERIAL FOR PROTECTION OF METAL SURFACES AGAINST CORROSION Russian patent published in 2009 - IPC C09D195/00 

FIELD: chemistry.

SUBSTANCE: invention relates to protective anti-corrosion compositions, representing inhibited oil compositions, intended for protecting metal surfaces, both inside surfaces and bottom, of all types of vehicles against corrosion. Invention relates to tixotropic material for protecting metal surfaces against corrosion, containing hard oil hydrocarbon, plasticiser, corrosion inhibitor, powder-like silicon-containing mineral and organic solvent, additionally containing glycerin ether of tall hard rosin, anti-oxidative additive, zinc phosphate, rheological additive and rheological additive activator, as hard oil hydrocarbon - oxidised bitumen, as corrosion inhibitor - mixture of corrosion inhibitors of anode, cathode and barrier type, as silicon-containing mineral - talc, and as plasticiser - oil-polymeric aromatic resin, with the following component ratio, wt %: oxidised bitumen - 30.0-40.0, oil-polymeric aromatic resin - 2.0-8.5, anti-oxidative additive - 1.0-2.5, corrosion inhibitor of anode type - 2.0-8.5, corrosion inhibitor of cathode type -6.0-10.5, corrosion inhibitor of barrier type -1.0-2.5, powder-like talc - 4.0-7.5, glycerin ether of tall hard rosin - 0.2-1.5, zinc phosphate - 2.0-4.0, rheological additive - 1.0-5.0, rheological additive activator - 1.5-7.0, organic solvent - to 100.

EFFECT: creating efficient tixotropic material for protecting metal surfaces against corrosion.
