    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 decomposition by high temperature. Fundamentals of the invention
    [002] Since the specific goals of replacing the Halon fire extinguishing agent were proposed to each country by the Montreal Convention in Canada in 1987, all countries in the world have dedicated themselves to researching new fire extinguishing technologies; people made great efforts to find fire extinguishing technology that was highly effective in extinguishing fire and had no environmental pollution.
    [003] Gas fire extinguishing systems, powder fire extinguishing systems, water-type fire extinguishing systems and the like, which are ecologically friendly, are widely used as substitutes for the fire extinguishing agent of Halon. The fire extinguishing mechanism of an inert gas fire extinguishing system, such as carbon dioxide, IG541 and the like, is mainly based on physical extinguishing, namely, muffling extinguishing by reducing the concentration of oxygen in an area of fire, such a method of extinguishing fire will easily threaten the safety of individuals. The powder fire extinguishing system implements fire extinguishing through the process in which the powder contacts sprinkled with the flame under the pressure of pressurized gas to generate the effect of physical and chemical inhibition; the fire sprinkler system achieves the purpose of fire control, fire inhibition and fire extinguishing under triple roles of cooling, muffling and thermal radiation insulation from water mist.
    [004] However, these fire extinguishing systems need to be stored under high pressure, which not only causes a greater volume, but also has the risk of physical explosion during the storage process; 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 caused by the gas fire extinguishing system pressure storage when in use.
    [005] In recent years, people have been researching fire extinguishing substances that can replace Halon, in which the Next Generation Fire Extinguishing Technology Project Group (NGP) of the Building and Fire Research Center of the US National Institute of Standards and Technology (NIST) carried out a large number of experimental research in the aspect of finding new fire extinguishing substances, the process includes: heating nitrogen, carbon dioxide and CF3H gas, and then using the gas heated to high temperature to heat test substances; the test substances are then decomposed under high temperature, which acts on the flame together with the gas. Through experiments, people find that products generated by the heating and decomposition of some test substances can obviously improve the fire extinguishing effect of nitrogen, carbon dioxide and CF3H gas (Halon Options Technical Working Conference, April 2001, Albuquerque , NM, Suppression of cup-burner diffusion flames by supereffective chemical inhibitors and inert compounds; Combustion and Flames 129: 221-238 (2002) Inhibition of Premixed Methane Flames by Manganese and Tin Compounds, Halon Options Technical Working Conference May 2000, inhibition flame by ferrocene, alone and with CO2 and CF3H).
    [006] However, the researchers in the project group ceased after the theoretical research in the laboratory, without applying the research checks in fire extinguishers in practice.
    [007] The existing aerosol fire extinguishing agent mainly includes type K and type S fire extinguishing agents, when analyzing comprehensively the performance characteristics, the disadvantages are mainly as follows: all aerosol fire extinguishing agents use extinguishing agents fire to generate an oxidation-reduction reaction, which releases a large number of gas and active particles, finally, to achieve the purpose of extinguishing fire of physical and chemical combination through the chain split reaction of the active particles and the muffling by covering a large number of gas. The aerosol fire extinguishing agent can release a large amount of heat while releasing the aerosol during the combustion reaction; in order to effectively reduce the temperature of the device and the aerosol, and to avoid a secondary fire, a cooling system needs to be added, which causes the heavy and complicated device structure, complicated technical process and high cost; due to the existence of the cooling system, a large number of active particles are deactivated, and the fire extinguishing performance is greatly reduced. Summary of the invention
    [008] Aiming at current situations existing fire extinguishing devices, and, in particular, the inherent defects of aerosol fire extinguishing systems, the purpose of this invention is to provide a fire extinguishing composition that does not require pressure storage, and is safer, more environmentally friendly and efficient.
    [009] The fire extinguishing composition in the present invention, namely, the fire extinguishing composition generating fire extinguishing substance through high temperature decomposition includes a fire extinguishing material that is capable of generating fire extinguishing substance through high decomposition temperature, where its content is greater than 80% by weight.
    [010] In addition to including the fire extinguishing material which is used as the main fire extinguishing material, and which can generate the fire extinguishing substance through high temperature decomposition, the fire extinguishing composition in the present invention can also add appropriately various additives that are commonly used in the field of fire extinguishing.
    [011] The fire extinguishing composition for generating fire extinguishing substance through high temperature decomposition in the present invention can achieve the following effects at the same time: first, the fire extinguishing composition capable of generating the fire extinguishing substance through high temperature decomposition can be decomposed to release the fire extinguishing substance at the time of heating, so as to reach the fire extinguishing target through the use of physical or chemical inhibiting effect, or the chemical or physical synergistic inhibiting effect of substances fire extinguishers; second, through the inhibition effect of the decomposition products, the effectiveness of the fire extinguishing agent of the fire extinguishing agent is further improved while reducing the post-combustion possibility of the fire source; third, the fire extinguishing composition can perform heat absorption quickly when decomposing under high temperature heating, thus it can effectively and quickly reduce the heat released by burning the pyrotechnic agent, which greatly reduces the temperature of the extinguisher device nozzle. fire and the sprayed substances, thus, the complicated cooling system of the fire extinguishing device is no longer needed, and the risks of generating a secondary fire are removed; fourth, the fire extinguishing composition can be easily processed and molded, and can be used independently or made compatible with the physical cooler; fifth, the fire-extinguishing composition has stable performance, and is easy to store for a long period of time; sixth, the fire extinguishing composition has low or no toxicity, is ecologically friendly and has excellent performance.
    [012] The fire extinguishing composition generating fire extinguishing substance through high temperature decomposition in the present invention is described below in detail.
    [013] The fire-extinguishing composition in the present invention includes the fire-extinguishing material generating the fire-extinguishing substance through high temperature decomposition, of which the content is greater than 80% by weight.
    [014] The flame-inhibiting mechanism of the fire extinguishing composition for generating fire extinguishing substance through high temperature decomposition is as follows:
    [015] The fire extinguishing composition can be decomposed to release the fire extinguishing substance under high temperature; the fire-extinguishing substance may have reactions with one or more of the free radicals O, OH, H that are necessary for the chain combustion reaction through the free radicals, in order to break the chain combustion reaction; and also reduce the partial pressure of oxygen through the physical effect to inhibit the flames, or it can simultaneously generate the physical and chemical inhibition effect to achieve the fire extinguishing effect together. At the same time, it can generate synergistic interaction with the pyrotechnic agent to additionally increase the effectiveness of the fire extinguishing agent, which greatly reduces the effective fire extinguishing time.
