Environmentally safe snow and ice dissolving liquid

摘要

The present invention relates to a snow-and ice dissolving composition comprising an aqueous solution of urea and ammonium-nitrate. The aqueous solution has a mass ratio of (4.5-5.5):(3.6-4.4):(6.3-7.7). In addition, 1.5-2.0 mass per cent of benzoic-acid and/or 0.10-0.25 mass per cent of benzo-or tolyl triazol as corrosion inhibitors can be added.
