Abstract

The invention discloses an aerosol fire extinguishing agent and a wet preparation method thereof. Water is adopted as a solvent and a reducing substance with the porous adsorption capacity is adopted as an incendiary agent, so that an oxidant achieves molecular-scale uniform dispersion. A powerful free radical quenching agent is added, so that the fire extinguishing effect is obviously improved. The wet preparation method for the aerosol fire extinguishing agent has no special requirement on granularity and water content of raw materials, reduces the process of crushing materials, improves the logistics speed of the production process, realizes high yield, and can remarkably reduce the production energy consumption and production cost. The dust pollution is avoided, and the safety and environmental protection in the production process are realized.

Description

Technical field: [0001] The invention belongs to the technical field of fire fighting and fire extinguishing, and relates to an aerosol fire extinguishing agent and a wet preparation method thereof. Background technique: [0002] Combustion refers to the exothermic reaction between combustibles and oxidants, usually accompanied by flames, glow or smoke. There are three necessary conditions for combustion to occur: combustibles, oxidizer, and temperature (reaching the ignition point), but this can only represent flameless combustion. Most of the combustion that is usually referred to is flaming combustion. Flame combustion must have the following four prerequisites: combustible, oxidizing agent, temperature (reaching ignition point) and uninhibited chain reaction. Having the necessary conditions for combustion does not mean that combustion will occur. Combustion must also meet the following four sufficient conditions: a certain concentration of combustibles, a certain conce...
