PROTECTIVE ANTICORROSION MATERIAL Russian patent published in 2002 - IPC

FIELD: corrosion prevention. SUBSTANCE: invention relates to protective anticorrosion compositions represented by inhibited crude oil compositions intended to prevent corrosion on hard- accessible motor transport surfaces. Composition contains, wt. %: solid petroleum hydrocarbons, 30-40; powdered silica, 0.1-10; rust inhibitor, 1-6; and organic solvent, the balance. Advantageously, as solid hydrocarbons, bitumen or petrolatum with 0.5-1.5% plasticizer is used. Rust inhibitor is a mixture including vinyltriethoxysilane or phenyltrichlorosilane, wbrlohexylamine, colophony soap, additive ("MIFOL") based on microbial fat, and barium-iron oxide pigment, each ingredient being present in amounts from 0.2 to 1.2 wt.%. EFFECT: achieved required protective effect and technological and working characteristics (thixotropy and heat resistance). 5 cl, 2 tbl
