    Technical field of the invention
    [001] The present invention relates to the field of fire extinguishing, relating to a use of a fire extinguishing composition and a fire extinguishing chemical, and in particular to a fire extinguishing composition that can generate extinguishing substance of fire through chemical reaction at high temperature. Fundamentals of the invention
    [002] Once people have verified that Halon's fire extinguishing agent can seriously damage the Earth's atmospheric ozone layer, the international community and the Chinese government began to eliminate Halon's fire extinguishing agent; gas fire extinguishing systems, powder fire extinguishing systems, water type fire extinguishing systems and the like, which are ecologically friendly, are widely used as the Halon fire extinguishing agent replacements.
    [003] The fire extinguishing mechanism of an inert gas, such as carbon dioxide, IG541 and the like, is mainly physical extinction, namely, extinguishing by muffling by reducing the oxygen concentration of a fire area; such a fire extinguishing method will easily threaten the personal safety of workers. The powder fire extinguishing system implements fire extinguishing through the process in which the sprinkling of powder under the effect of pressurized gas contacts the flame to generate a physical and chemical inhibition effect. The water fire extinguishing system achieves the purpose of fire control, fire inhibition and fire extinguishing under three functions of water mist: cooling, muffling and thermal radiation isolation.
    [004] However, these fire extinguishing systems need to be stored under high pressure, not only is the volume of these systems being greater, but also the risks of physical explosion during the storage process are greater; the document “The Security Analysis of Gas Fire extinguishing System” (Fire Science and Technology 2002 21 (5)) analyzes the risks of the gas fire extinguishing system, and lists the safety accidents of the gas extinguishing system pressure storage.
    [005] The aerosol fire extinguishing technology attracts a lot of attention, since it has no toxicity, corrosion, high volume efficiency, long storage period, total flooding, full range of fire extinguishing and the like; from the end of the last century to the last ten years, aerosol technology has developed rapidly, related patents have emerged endlessly. For example, the Russian patents: RU2230726, RU2184587, RU2214848, RU2150310, RU2108124, RU2091106, RU2076761, and the domestic patents: CN1739820A, CN1150952C, CN1222331C.
    [006] The disadvantages of aerosol fire extinguishing are that: the fire extinguishing activity generated by itself is severely attenuated after being filtered by a cooling layer, and the fire extinguishing effectiveness is greatly influenced. Summary of the invention
    [007] Aiming at the research situations above, the present invention uses the composition that can generate a fire extinguishing substance through chemical reaction at high temperature to fire extinguishers.
