Abstract

The invention relates to a water-based fire extinguishing agent, which comprises, by mass, 1-6% of an inorganic salt, 0.5-5% of a surfactant, 1-5% of a foaming agent, 3-10% of a flame retardant, 4-10%of an anti-freezing agent, 0.1-1% of a penetrant, 2-3% of an emulsifier, and the balance of water, wherein the surfactant uses a combination of a fluorine surfactant and a hydrocarbon surfactant, andthe fluorine surfactant is an anionic gemini fluorine surfactant having a fluorocarbon chain length of 4 carbons. According to the present invention, the fire extinguishing agent adopts the self-madefluorocarbon surfactant, does not contain persistent organic pollutants, can be rapidly degraded, cannot pollute the environment, and has excellent fire extinguishing performance.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a water-based fire extinguishing agent produced by using an anionic twinned fluorocarbon surfactant with a fluorocarbon chain length of 4 carbons. Background technique [0002] Water-based fire extinguishing agent is a new type of high-efficiency fire extinguishing agent developed since the 1980s. The main components of this type of foam fire extinguishing agent are surfactants and stabilizers, cosolvents, antifreeze agents, flame retardants, gas generating agents and made with water. When the water-based fire extinguishing agent is sprayed onto the burning oil surface, its foam can spread rapidly on the oil surface, forming a layer of water film, inhibiting the evaporation of the oil and isolating the air, so as to achieve the purpose of extinguishing the burning of the oil. Most of the foam fire extinguishing agents currently used contain PFOA / PFOS fluorine-c...
