Problems solved by technology

[0004] Since alcohol is a polar flammable molecule, and the flame temperature exceeds 1000°C, which is higher than that of other common types of fires, the commonly used fire extinguishing agents, such as dry powder fire extinguishing agent and foam fire extinguishing agent, are difficult to extinguish the fire caused by alcohol, even resistant to fire. The efficiency of soluble water film-forming foam fire extinguishing agents in extinguishing alcohol fires is still low, which is not enough to deal with large-scale and flowing alcohol fires

Abstract

The invention discloses a water-based multi-phase system fire-fighting agent for quickly extinguishing alcohol open flames and a preparation method thereof, comprising the following components in parts by weight: 2-30 parts of core raw materials, carbonic acid modified by octoxynol 5-7 parts of ammonium, 2-6 parts of dispersant, 0.1-0.5 part of dispersing aid, 0.03-0.08 part of antibacterial agent, 40-60 parts of water solvent; the core raw materials are bentonite, kaolin, attapulgite, chemically modified One or more of mica, chemically modified graphite and phosphorus. The ammonium carbonate modified by octoxynol of the present invention, after being exposed to fire, releases carbon dioxide, ammonia or other molecules due to thermal decomposition, and these molecules themselves have an inhibitory effect on flame and promote fire extinguishing; non-metallic mineral particles such as mica and Graphite has a stable molecular structure and high molecular thermal stability. It cannot burn or support combustion. It can isolate air and cause combustion suffocation. At the same time, it can quench free radicals and interrupt the combustion reaction chain, so that the combustion flame can be extinguished quickly.
