ANTI-ICING LIQUID Russian patent published in 2004 - IPC

FIELD: special-destination fluids.

SUBSTANCE: invention relates to compositions of anti-icier liquids serving for removal of ice deposits (hoarfrost, rime, snow, ice) from aircraft surfaces as well as to prevent on-land reicing of aircrafts when they are prepared to takeoff. Anti-icing liquid contains, wt %: alkylenepolyol, 50-55; benzenesulfonate salt of methyldiethylaminomethyl derivatives of fatty alcohol diethylene glycol ethers, 0.3-0.4; stearic acid, 0.1-0.2; quaternary methyl sulfate salt of stearic acid/diethanolamine condensation product, 0.15-0.2; industrial mixture of monoalkylphenol polyethylene glycol ethers based on propylene trimers having following empirical formula: C₉H₁₉C₆H₄O(C₂H₄O)_nH, wherein n = 9-12 is averaged number of ethylene oxide moles attached to 1 mole of alkylphenols, 0.3-0.4; sodium tetraborate as corrosion inhibitor, 0.5-1.5; and water, the balance.

EFFECT: enhanced anti-icing property.
