Abstract

The invention discloses a fire extinguishing agent. The fire extinguishing agent is characterized by consisting of the following components in percentage by mass: 1.5-3% of a non-ionic fluorocarbon surfactant, 0.1-1% of a foam stabilizer, 2-4% of a hydrocarbon surfactant, 0.1-0.5% of a thickening agent, 0.1-0.5% of an anti-burning agent, 2-5% of a cosolvent, 1-5% of an organic solvent, 0.2-2% of a buffer solution, 0.1-0.5% of a metal corrosion inhibitor, 4-10% of an anti-freezing agent, 0.2-0.5% of a bacteriostatic agent, 0.5-2.5% of a chelating agent and the balance water. The fire extinguishing agent disclosed by the invention is rich and stable in forma, spreads quickly on an oil surface, is self-inspected according to the PRC National Standards GB 15308-2006 ( Foam Fire Extinguishing Agent), is qualified in performance and is excellent in fire extinguishing performance. Besides, the components of the fire extinguishing agent do not rely on imports, so that the product is relatively low in price, can be diluted with fresh water or seawater for use, is wide in scope of application, and has a very great market prospect.

Description

Technical field [0001] The invention relates to a fire extinguishing agent. The invention also relates to a preparation method of the fire extinguishing agent. The invention belongs to the field of fire extinguishing agent development. Background technique [0002] Among the extinguishing agents currently used to extinguish oil fires, the aqueous film-forming foam extinguishing agent has the best extinguishing effect due to the double extinguishing effect of its water film and foam. [0003] The fire extinguishing effect of the aqueous film-forming foam extinguishing agent is shared by the water film layer and the foam layer floating on the oil surface. When the fire extinguishing agent is sprayed onto the fuel surface, the foam quickly spreads out on the oil surface and precipitates liquid to cool the oil surface. The precipitated liquid spreads on the oil surface at the same time to form a water film, which together with the foam layer inhibits fuel evaporation, which not only i...
