Abstract

An aqueous fire extinguishing agent and a preparation method thereof are provided, which are used for making a throw-type fire extinguisher. The aqueous fire extinguishing agent is composed of two compositions of A and B. The composition A is a fortified water added with a flame retardant (e.g., one or more of ammonium chloride, diammonium hydrogen phosphate and ammonium polyphosphate), a wetting agent (e.g., alkyl polyglycoside) and a colloid (e.g., polyacrylamide solution). The composition B is a regulator. After the composition A and the composition B are mixed, a discharge rate/speed of fire extinguishing substances is increased, so that an escape passage/route can be opened up quickly.
