Abstract

The invention discloses a superfine dry powder extinguishing agent. Raw materials used for preparing the superfine dry powder extinguishing agent mainly comprise, by mass, 7-10 parts of alkali residues, 30-40 parts of sodium bicarbonate, 0.5-1 part of talcum powder, 5-8 parts of marlstone, 1-3 parts of xonotlite, 30-45 parts of ammonium sulfate, 3-7 parts of ammonium polyphosphate, 10-20 parts of gypsum, 1-4 parts of stannic oxide, 2-5 parts of silicon nitride, 1-2 parts of silicone oil and 0.4-0.6 part of polybutylene. The prepared superfine dry powder extinguishing agent is good in mobility and hydrophobicity, high in anticaking capacity and fire extinguishing performance, and shortened in fire extinguishing time.

Description

technical field [0001] The invention relates to the field of fire extinguishing agents, in particular to an ultrafine dry powder fire extinguishing agent and a preparation method. Background technique [0002] Ultrafine dry powder fire extinguishing agent is a superfine powder fire extinguishing agent with high fire extinguishing efficiency, dry and easy to flow. It is mainly composed of active fire extinguishing components, crushing aid components, hydrophobic components, inert filler components, etc. Among them, the fire extinguishing component is the core of the ultra-fine dry powder fire extinguishing agent, and other components work around this core. The principle of fire extinguishing is mainly as follows: First, the volatile decomposition products of inorganic salts in the powder and the free radicals or active groups produced by the fuel during the combustion process undergo chemical inhibition and secondary catalysis, so that the chain reaction of combustion is int...
