Patent ID: 10092786

Abstract:
The present invention relates to a fire-extinguishing composition containing an aldehyde/ketone compound. The fire-extinguishing composition releases a great quantity of active fire-extinguishing particles by making use of the heat generated from combustion of a pyrotechnic agent. The fire-extinguishing composition containing an aldehyde/ketone compound in the present invention reacts at a high temperature to generate free radicals and takes reaction with one or more of O-, OH-, H-free radicals necessary for a chain combustion reaction through the free radicals, so as to cut off the chain combustion reaction and take physical and chemical inhibiting effects to jointly achieve a fire extinguishing effect at the same time. Meanwhile, it takes synergistic interaction effects with the pyrotechnic agent to further raise the fire extinguishing efficiency of the fire extinguishing agent and greatly shorten the effective fire extinguishing time.
