The present invention relates to a fire-extinguishing composition comprising an organic acid compound, wherein the fire-extinguishing composition comprises an organic acid compound. The content of the organic acid compound is 50% by mass or more, and preferably 70% to 90% by mass. The organic acid compound according to the present invention may absorb heat and be decomposed at a high temperature, and release a fire-extinguishing substance. The fire-extinguishing substance may react, by means of free radicals, with one or more of O�,OH�,H� free radicals that are necessary for chemical-looping combustion, thus cutting off the chemical-looping combustion, or may reduce the oxygen partial pressure by physical action to inhibit the flame, or achieve the fire-extinguishing effect by both the physical and chemical inhibition effects. At the same time, the organic acid compound achieve a synergistic effect together with a firework powder, thereby further improving the fire-extinguishing performance of the fire-extinguishing agent, and greatly shortening the effective fire-extinguishing time. |
