The present invention relates to a fire extinguishing composition comprising carboxylic acid derivatives, the fire extinguishing composition utilizing heat generated by combustion of pyrotechnic powder to release a large amount of effective fire extinguishing particles. The fire extinguishing composition comprising carboxylic acid derivatives decomposes at a high temperature to generate free radicals; the free radicals react with one or more of the free radicals of O, OH, and H necessary for a chain combustion reaction, to cut off the chain combustion reaction, while producing physical and chemical inhibitory effect to achieve fire extinguishing result. In addition, the fire extinguishing composition comprising carboxylic acid derivatives generates synergistic effect with the pyrotechnic powder, further improving the fire extinguishing efficacy of the fire extinguishing agent, and greatly shortening effective fire extinguishing time. |
