A fire extinguishing composition containing organic acid compounds

Abstract

The invention relates to a fire extinguishing composition containing organic acid compounds, the fire extinguishing composition contains organic acid compounds; wherein the content of organic acid compounds is more than 50 (mass) %, preferably 70 (mass) % to 90 ( mass) %; the organic acid compound of the present invention can absorb heat and decompose at high temperature, and release the fire extinguishing substance, which can pass through free radicals and chain combustion reaction necessary O , OH , H free radicals One or more of them react, thereby cutting off the chain combustion reaction, and can also reduce the oxygen partial pressure by physical action to suppress the flame, or simultaneously have physical and chemical inhibition to achieve the fire extinguishing effect. The agents produce a synergistic effect, which further improves the fire extinguishing efficiency of the fire extinguishing agent and greatly shortens the effective fire extinguishing time.

Description

technical field [0001] The invention belongs to the technical field of aerosol fire extinguishing, in particular to a fire extinguishing composition which can be decomposed to produce fire extinguishing substances when heated. Background technique [0002] Since the 1987 Montreal Convention in Canada put forward specific targets for countries to replace halon fire extinguishing agents, countries all over the world have been committed to the research of new fire extinguishing technologies. It is people's efforts to have high fire extinguishing efficiency and non-polluting fire extinguishing technology. direction. Gas fire extinguishing system, dry powder fire extinguishing system and water system fire extinguishing system have been widely used as substitutes for halon fire extinguishing agents because they are harmless to the environment. [0003] However, these fire extinguishing systems all require high-pressure storage, which is not only large in size, but also has the da...

AI Technical Summary

Problems solved by technology

The aerosol generating agent releases a large amount of heat when it undergoes a combustion reaction to release the fire extinguishing substance. In order to effectively reduce the temperature of the device and the aerosol and avoid secondary fires, it is necessary to increase the cooling system, resulting in complex and bulky device structure and complicated process flow. , the cost is high, but due to the existence of the cooling system, a large number of active particles are deactivated, resulting in a greatly reduced fire extinguishing performance
