Принадлежит:

The present invention relates to a fire extinguishing composition comprising heterocyclic compounds, 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 heterocyclic compounds reacts 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 effects to achieve fire extinguishing results. 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.
