Abstract
Disclosed in the present invention is a metallic oxysalt fire extinguishing composition; the fire extinguishing composition comprises a metallic oxysalt compound and a flame-retardant extinguishing component, their proportion being respectively as follows: 30%-95% of the metallic oxysalt compound and 5%-70% of the flame-retardant extinguishing component. A pyrotechnic composition is used as the heat source and the power source of the fire extinguishing composition in the present invention, by igniting the pyrotechnic composition, the fire extinguishing composition being heated and subjected to a decomposition reaction by using high temperature generated by means of combustion of the pyrotechnic composition, large quantities of substances capable of extinguishing fire being generated, and the fire extinguishing substances along with the pyrotechnic composition being ejected from the nozzle of a fire extinguishing apparatus, thus achieving the purpose of extinguishing fire. The fire extinguishing composition of the present invention is simple in composition, stable in performance, easy to store for a long time, non-toxic, and has excellent environment-friendly properties.
