FIRE EXTINGUISHING COMPOSITION COMPRISING ORGANIC ACID COMPOUND

摘要

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.
