Fire-Extinguishing Composition
This application is a divisional application of PCT/CN2016/107856 filed on 30 November 2016, the contents of which are to be taken as incorporated herein by reference.
PCT/CN2016/107856 claims the benefit of Chinese application No. 201510867612.5, filed 1
December 2015, the entire contents of which are also incorporated herein by reference.
Field of the Invention
The present invention pertains to the technical field of aerosol fire extinguishing, particularly to a thermal aerosol fire-extinguishing composition.
Background of the Invention
Since the specific target of each country for substitution of Halon fire-extinguishing agents was put forth in Canadian Montreal Convention in 1987, all countries in the world have been committed to the research of new fire-extinguishing techniques. Fire-extinguishing techniques with high fire-extinguishing efficiency and no environmental pollution are directions of our effort.
A gas fire-extinguishing system, a powder extinguishing system, a water fire-extinguishing system and the like are harmless to environment, so they are selected as substitutes of Halon fire-extinguishing agents and are widely used. The fire-extinguishing mechanism of the fireextinguishing systems of carbon dioxide, IG541 and inert gases mainly relies on physical fireextinguishing. The fire is put out by lowering the concentration of oxygen in the firing area. This fire-extinguishing method would easily threaten human safety. The powder extinguishing system puts out a fire by spraying powder under the action of pressurized gas to contact flame and realize physical and chemical suppression effect. A water mist fire-extinguishing system achieves the aspects of controlling, suppressing and putting out a fire through triple actions of cooling, smothering, and isolation of thermal radiation by using water mist.
However, all these fire-extinguishing systems need high pressure storage. Not only the volume is large but also there is a risk of physical explosion during storage. A document Safety
Analysis of Gas Fire-extinguishing System (Fire Science and Technology 2002 21(5))
2018100771 08 Jun2018 analyzes the risk of a gas fire-extinguishing system and enumerates the safety accidents triggered by the stored pressure gas fire-extinguishing system during use.
The existing thermal aerosol fire-extinguishing agents are mainly type S and type K fireextinguishing agents. The comprehensive analysis of their performance and features indicates that their fire-extinguishing mechanism is that the thermal aerosol fire-extinguishing agents take a redox reaction through agent combustion to release a great quantity of gas and active particles and one aspect of integrated chemical and physical fire-extinguishing is realized through the chain scission reaction of the active particles and covering and smothering of a great quantity of gas. The disadvantage of the thermal aerosol fire-extinguishing agents is that the thermal aerosol fire-extinguishing agent will release a great quantity of heat while it takes the combustion reaction to release the thermal aerosol, which may cause a secondary combustion. In order to effectively reduce the temperature of the device and aerosol and avoid the secondary fire, a cooling system needs to be added. The cooling materials of the existing thermal aerosol fire-extinguishing units can reduce the temperature of products, but they also greatly weaken the fire-extinguishing performance of the products. In order to compensate the loss in the fire-extinguishing performance caused by the cooling system, many products either lower the fire-extinguishing level or continuously increase the mass of the actual fireextinguishing agent, rendering the increase of product volume and the decrease of use efficiency, which results in a complex and cumbersome structure of the device, such as the S type fire-extinguishing agent. The traditional K type fire-extinguishing agent, however, has high fire extinguishing efficiency and small volume, but the sediment thereof is corrosive and would bring secondary damage.
Therefore, there is an urgent need in the market for a fire-extinguishing composition which not only ensures the fire extinguishing efficiency of the K type fire-extinguishing agent, makes the fire-extinguishing equipment small in size, light in weight and easy to be installed, but also ensures that the fire-extinguishing particles released would not produce secondary damage to the places where the fire extinguishing is carried out, in particular some places having electrical equipment, and has good corrosion resistance.
The discussion of documents, acts, materials, devices, articles and the like is included in this specification solely for the purpose of providing a context for the present invention. It is not suggested or represented that any or all of these matters formed part of the prior art base or
2018100771 08 Jun2018 were common general knowledge in the field relevant to the present invention as it existed before the priority date of each claim of this application.
Where the terms “comprise”, “comprises”, “comprised” or “comprising” are used in this specification (including the claims) they are to be interpreted as specifying the presence of the stated features, integers, steps or components, but not precluding the presence of one or more other features, integers, steps or components, or groups thereof.

The flame suppression mechanism of the fire-extinguishing composition of the present 5 invention is as follows:
When used, the pyrotechnic agent is used as a source of heat and a source of power, and with the heat released from ignition and combustion of the pyrotechnic agent, the fire-extinguishing composition is further decomposed at a high temperature to release fire-extinguishing substances, which may react with one or more of O·, OH·, H· free radicals necessary for the chain combustion reaction via free radicals, thereby cutting off the chain combustion reaction.
It is also possible to reduce the oxygen partial pressure by physical action to suppress the flame, or that physical and chemical inhibitions may take place simultaneously to achieve fire extinguishing. Meanwhile, they take a synergistic interaction effect with the pyrotechnic agent to further raise the fire extinguishing efficiency of the fire-extinguishing agent and greatly shorten the effective fire extinguishing time.
As compared with the existing thermal aerosol fire extinguishing agents, the fire-extinguishing composition of the present invention has the following advantages:
1. The aromatic organic acid compound and the alcohol-based compound in the fireextinguishing composition of the present invention may undergo sublimation by endothermic process, decomposition, and reaction between each other at a high temperature to generate a large number of nanometer-level effective fire-extinguishing particles and a plurality of free radicals, cutting off the combustion reaction chain; and function in fire extinguishing along with the reaction products of the thermal aerosol generating agent, which further improves the fire extinguishing efficiency of the fire extinguishing agent and shortens the effective fire extinguishing time.
2. The fire-extinguishing composition of the present invention compensates for the loss in the performance of the aerosol generating agent caused by a general cooling layer, and also enhances the fire-extinguishing performance of the entire fire-extinguishing product, while reducing the temperature at a nozzle of the fire-extinguishing device. Therefore, the fire-extinguishing composition is safer, would not do harm to fire fighters and also avoids secondary fires.
