The invention relates to fire-safety technology, in particular, to liquid compositions for extinguishing fires of solid combustible materials, combustible liquids, gaseous substances, live electric installations under a voltage of up to 1000 V, and for using as an impregnating liquid for fireproofing. The composition can be used for fire protection and preservation of wooden structures and products, textile materials, carpet floorings and polymers. In order to achieve the technical result, a fire-retardant composition comprising urea, surfactant, anticorrosion additive and water, further includes, in accordance with the invention, orthophosphate, ammonium polyphosphate and sulphuric acid with the following proportion of components, wt.%: urea 10-15, orthophosphate 10-15, ammonium polyphosphate 0.5-1.5, anticorrosion additive 0.5-1.5, sulphuric acid 0.2-1.0, surfactant 0.5-1.0, water - the rest. The invention ensures high efficiency of the fire-retardant composition and broader functional capabilities thereof. |
