  • Patent number: 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.

  • Patent number: 9662522
    Abstract: The present disclosure relates to a fire extinguishing composition containing saccharide and a saccharide derivative, comprising a saccharide derivative, a saccharide material and an auxiliary fire extinguishing agent, whose mass percentages are respectively: saccharide derivative 30%-60%, saccharide material 10%-40%, and auxiliary fire extinguishing agent 10%-30%. The fire extinguishing composition uses a pyrotechnic agent as a heat source and a power source, is heated and decomposed or reacts by using the heat of burning of the pyrotechnic agent, to generate a fire extinguishing material to be sprayed together with the fireworks agent, thereby achieving the fire extinguishing purpose. The fire extinguishing composition of the present disclosure uses a saccharide derivative and a saccharide material as primary ingredients, uses a pyrotechnic agent as a heat source and a power source, and is easily decomposed after being heated to generate non-toxic and harmless gas.

  • Publication number: 20170043196
    Abstract: The present invention relates to a fire-extinguishing composition containing a heterocyclic 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 a heterocyclic 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.
