Abstract

The invention relates to a neutral environmentally-friendly water-based fire extinguishing agent and a preparation method thereof. The neutral environmentally-friendly water-based fire extinguishing agent comprises water, a first fire extinguishing component, a second fire extinguishing component, citric acid and a water-soluble surfactant component, wherein the first fire extinguishing component comprises two or more of such inorganic compounds as ammonium dihydrogen phosphate, urea, potassium carbonate and ammonium monohydric phosphate; the second fire extinguishing component comprises one or more of potassium sulfate, potassium bicarbonate, sodium phosphate, organic acid and potassium acetate; and the water-soluble surfactant component comprises two or more of sodium lauryl sulfate, hexadecyl trimethyl ammonium chloride, perfluorooctane surfapropyl betaine, sodium octyl sulfate and sodium decyl sulfate. The preparation method comprises the following steps: adding water into a stirring machine, and sequentially adding all the components while stirring, so as to obtain a product finally. The finally prepared neutral environmentally-friendly water-based fire extinguishing agent can be applied to A-class, B-class and F-class fire disasters, and has the advantages that the corrosion problem can be solved without adding an antirust agent; the low-temperature (minus 25 DEG C) problem can be solved without adding an anti-freezing agent; and the environmentally-friendly effect can be achieved.

Description

technical field [0001] The invention belongs to the field of fire protection, and in particular relates to a neutral environment-friendly water-based fire extinguishing agent and a preparation method thereof. Background technique [0002] The water-based fire extinguishing agent produced by the existing technology needs to be based on the proportion of water quality of 94% to 97%, and is mixed with water film-forming foam, protein foam, fluorinated protein foam, synthetic surfactant foam, ethanol-based foam, etc. After use, and the fire extinguishing performance is mainly the performance of Class B fire (oil fire), but the performance of Class A fire (general fire) is weak, and the ability to extinguish Class F fire (edible oil fire) is almost no; especially When used for petroleum compound fires (high-heat fires such as plastics, rubber, leather, tires, etc.) that often occur now, the performance is weak, and with the extension of the fire extinguishing time, toxic gases ar...
