FIELD: icing protection.
SUBSTANCE: invention provides antiicing composition designed to remove snow-ice coverings from pavement, which composition contains 3.0-3.8% calcium chloride, 9.8-10.8% magnesium chloride, 7.8-8.8% sodium chloride, and 0.015-0.09% corrosion inhibitor selected from group consisting of urea, sodium nitrite, monosodium phosphate, disodium phosphate, borax, poly(benzylammonium chloride), poly(benzylpyridinium chloride), polyethylene-polyamines, triethanolamine, benzotriazole, tolyltriazole, sodium benzoate sodium 2-aminobenzoate, caprolactam, oxyethylated monoalkylphenols and dialkylphenols, and mixtures thereof. Composition is provided in the form of aqueous solution having pH 5.5 to 8.0.
EFFECT: achieved softer and more environmentally friendly effect as compared to calcium chloride and sodium chloride-based analogs and preserved relatively low freezing temperature, all at preparation simplicity and low expenses.
