Abstract

The invention relates to the field of fire extinguishing materials, specifically relates to a water-based fire extinguishing agent, and particularly relates to an environment-friendly water-based fireextinguishing agent which uses a temperature-sensitive hydrogel as a fire extinguishing agent. The invention discloses a preparation method of the environment-friendly water-based fire extinguishingagent which uses water as a solvent; 0.6-0.8% of temperature-sensitive hydrogel, 1.5-3% of an inorganic salt, 6-8% of an anti-freezing agent, 5-10% of a stabilizer and 3-10% of a hydrocarbon surfactant are added. The environment-friendly water-based fire extinguishing agent provided by the invention using the temperature-sensitive hydrogel as the fire extinguishing agent to replace the use of a traditional fluorine-containing surfactant has characteristics of biodegradability, high viscosity, good wetting performance and excellent jetting performance, and can be widely applied to rescue in various Class A fires and Class B fires.

Description

technical field [0001] The invention relates to the field of fire-fighting and fire-extinguishing materials, in particular to a water-based fire-extinguishing agent, in particular to an environment-friendly water-based fire-extinguishing agent using temperature-sensitive hydrogel as the fire-extinguishing agent. Background technique [0002] Water-based fire extinguishing agents, such as fine water mist, three-phase foam, aqueous film-forming foam, hydrogel, etc., are a class of traditional fire extinguishing agents that can improve the fire extinguishing ability of water by adding active ingredients to water. It is not only the most common fire extinguishing agent in daily life, but also one of the most effective fire extinguishing agents for building fires and forest fires. Among them, the foam fire extinguishing agent with fluorocarbon surfactant as the main raw material has the advantages of easy availability of raw materials, simple production process, strong resistance...
