Abstract

The invention relates to an organic acid compound-containing fire extinguishing composition, which contains an organic acid compound. The content of the organic acid compound is over 50(mass)%, preferably 70(mass)%-90(mass)%. Under high temperature, the organic acid compound can absorb heat and decompose to release a fire-extinguishing substance, which can react with one or several of the O., OH., H. free radicals necessary for a chain combustion reaction through a free radical, thus cutting off the chain combustion reaction. Also, the oxygen partial pressure can be reduced through a physical effect so as to suppress flames. Or a fire extinguishing effect can be realized by simultaneous physical and chemical inhibition together. At the same time, the fire extinguishing composition and a pyrotechnic agent can have a synergistic effect, thus further improving the fire extinguishing efficiency of a fire extinguishing agent and greatly shortening 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...
