Problems solved by technology

However, the commonly used water-based fire extinguishing agents have low fire extinguishing grades and poor re-ignition resistance, which seriously affects the fire-extinguishing effect of water-based fire extinguishing agents.
In addition, most gasoline currently contains a certain amount of polar organic solvents such as methanol or denatured ethanol, which have a certain destructive effect on foam.

Abstract

The invention discloses an environment-friendly water-based fire extinguishing agent and a preparation method thereof. The water-based fire extinguishing agent comprises a C6 short-chain fluorocarbon surfactant, a C6 fluorine-containing polymer, a foaming agent, a flame retardant and an organic solvent, and the mass part ratio of the C6 short-chain fluorocarbon surfactant to the C6 fluorine-containing polymer to the foaming agent in the fire extinguishing agent is (3-10): (3-10): (8-19). In addition, the fire extinguishing agent further comprises an anti-freezing agent. The water-based fire extinguishing agent has the advantages of being low in surface tension, wide in application range, high in fire extinguishing speed and good in after-combustion resistance, and has the high fire extinguishing grade. The water-based fire extinguishing agent does not contain PFOS and PFOA, is not prone to being enriched in the environment, has no pungent smell, can be completely biodegraded after being sprayed, and is easy to clean after fire extinguishing.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing agents, and particularly relates to an environment-friendly water-based fire extinguishing agent and a preparation method thereof. Background technique [0002] The fire-extinguishing mechanism of water-based fire extinguishing agent is to disperse on the surface of the burning object while precipitating liquid to cool the surface of the burning object, and forming a layer of water film and micro-foam layer on the surface of the burning object to seal the surface of the burning object, isolating the air and forming a barrier. The thermal barrier, and the liquid after absorbing the heat vaporizes and dilutes the oxygen content in the air above the surface of the burning object, which has a suffocating effect on the burning object, thereby achieving the effect of extinguishing the fire. [0003] Water-based fire extinguishing agents have been paid more and more attention by researchers an...
