The present invention relates to a composite chemical fire extinguishing agent that can be effectively used against a wide variety of fire types, such as general fires, oil fires, electrical fires, etc., and has excellent high performance. It is highly effective and can achieve quick and reliable fire extinguishing effect with a small amount of use, and it is also effective in preventing damage to rooms, equipment, fixtures, materials, and other items other than the fire area, unlike conventional extinguishing agents. The present invention relates to a unique complex chemical fire extinguishing agent that is free from contamination and has excellent safety because it exhibits high performance fire extinguishing effects at low concentrations and low toxicity. It has been known that monobromotrifluoromethane has a chemically reactive fire extinguishing effect, which is presumed to be due to some kind of negative reaction effect, and that dibromotetrafluoroethane also has a fire extinguishing effect.
On the other hand, cyanamide derivative flame retardants such as guanidine phosphate, guanidine sulfamate, and other guanidine salts are used as flame retardants that are impregnated into paper and other cellulosic materials. The former, bromofluorinated hydrocarbon compounds, are said to be particularly useful for initial fire extinguishing, but they often have the disadvantage of causing re-ignition after extinguishing, and the latter, cyanamide derivative flame retardants, are not suitable for use as extinguishing agents. does not show satisfactory fire extinguishing effect. The present inventor has conducted research in order to provide a satisfactory fire extinguishing agent that has excellent fire extinguishing effects. As a result, the combination of monobromotrifluoromethane and dibromotetrafluoroethane, which have problems with re-ignition, and a cyanamide derivative flame retardant, which does not have a fire extinguishing effect that can be used as a fire extinguisher, has proven to be extremely effective. It was discovered that a compound chemical fire extinguishing agent with high performance can be provided. According to the research of the present inventor, a composite chemical fire extinguishing agent containing a specific range ratio of the above three as an active ingredient exhibits a rapid and reliable fire extinguishing effect even when used in a small amount, and prevents the trouble of re-ignition. It exhibits excellent extinguishing effect in extinguishing a wide variety of types of fires without the fear of fire extinguishing, and is also extremely safe and has excellent extinguishing effects without the contamination problems associated with the use of conventional extinguishing agents. A unique compound chemical fire extinguishing agent has been discovered. The fire extinguishing mechanism is complex, and the details of the fire extinguishing mechanism that uses a combination of the three mentioned above are unknown, but as will be shown experimentally later using examples and comparative examples, it is possible to use any one of the three above. Even if you omit
In view of the fact that the above-mentioned unique and outstanding fire-extinguishing effect of the composite chemical fire-extinguishing agent of the present invention is inhibited, it is presumed that an interactive mutual effect on fire-extinguishing occurs among the three components. Of course, the present invention is not limited to this kind of speculation.
There are no restrictions. Accordingly, an object of the present invention is to provide a composite chemical fire extinguishing agent having outstanding and unique fire extinguishing effects. The above objects and many other objects and advantages of the present invention will become more apparent from the following description. The composite chemical fire extinguishing agent of the present invention comprises (A) 100 parts by weight of monobromotetrafluoromethane, (B) about 20 to about 250 parts by weight, preferably about 25 to about 230 parts by weight, more preferably about 25 to about 200 parts by weight, (C) about 2 to about 250 parts by weight of cyanamide derivative flame retardant, preferably about 5 to about 200 parts by weight, more preferably about 5 to about 100 parts by weight, especially about 5 to about 50 parts by weight. Contains the following three parts by weight as active ingredients. Regarding a preferred example of the composite chemical fire extinguishing agent of the present invention, the blending ratio of components (A), (B), and (C) in % of each component in a total of 100% by weight of the agent is shown as follows. Can be done. Component (A) about 50 to about 75% by weight, component (B) about 25 to about 35% by weight, and component (C) about 2 to about 15% by weight. The above (A) monobromotrifluoromethane (CBrF 3 ) is a gaseous compound at room temperature with a boiling point of around -58°C (1 atm), and (B) dibromotetrafluoroethane (BrF 2 C-CF 2 Br) has a boiling point of approximately 47℃
It is a liquid compound at room temperature around (1 atm). These may contain small amounts of compounds in which some hydrogens are unsubstituted and other compounds containing halogen substitutions, and in the present invention, compounds in which these related compounds coexist can also be used. . Examples of such related compounds include CHF 3 , CF 4 , CHBrF 2 ,
CBr2F2 , CBrF3 , CHClF2 , CCl2F2 , CClF3 ,
F 2 HC−CHF 2 , F 3 C−CF 3 , BrFHC−CHFBr,
Examples include Br 2 FC-CFBr 2 , F 2 ClC-CClF 2 and other compounds. Various guanidine compounds are known as the cyanamide derivative flame retardant, and typical examples include guanidine inorganic acid salts such as guanidine phosphate and guanidine organic acid salts such as guanidine sulfamate. A plurality of such flame retardants can be used in combination. In the composite chemical extinguishing agent of the present invention, (A) monobromotrifluoromethane itself can serve as a propellant gas together with the extinguishing agent components, so there is no need to use a propellant gas. But you can use it if you want. For example, pressurization with an inert gas such as nitrogen gas can be employed. The composite chemical extinguishing agent of the present invention is
Components (A), (B), and (C) can be stored in a pressure-resistant container equipped with a suitable spray nozzle and used as a composite chemical extinguishing agent in a jet-discharge type fire extinguisher. Regarding component (A) in the composite chemical fire extinguishing agent of the present invention
If the blended amount of component (B) deviates from the above range and becomes too small, the time required for extinguishing the fire and the amount of extinguishing agent used will be extended and increased several times, which is the advantage of the composite chemical extinguishing agent of the present invention. The additive fire-extinguishing effect that can achieve rapid fire-extinguishing effect is lost at the amount used. Also, if the amount is too much, the extinguishing effect will be further lost, and if the amount is too large,
Since the amount of extinguishing agent used and the time required will increase over a longer period of time, it is preferable to use the extinguishing agent by appropriately selecting the amount within the above range. Furthermore, if the blended amount of component (C) relative to component (A) is outside the above range and becomes too small, there is a problem that once the fire has been extinguished, it may easily re-ignite, and the time required for extinguishing the fire and the amount of extinguishing agent used may also be inadequate. It tends to be profitable. On the other hand, if the amount is excessive, the extinguishing time and the amount of extinguishing agent used will be unduly extended and increased, and the advantages of the composite chemical extinguishing agent of the present invention will be lost. Furthermore, even if any one of the three essential components of the composite chemical fire extinguishing agent of the present invention is omitted, the additive fire extinguishing action and effectiveness of the composite chemical fire extinguishing agent of the present invention will deteriorate; for example,
When component (A) is omitted, as shown in Comparative Example 3 later, the extinguishing time is 8 to 15 times longer and the required amount of extinguisher is 7 to 11 times that of the extinguishing agent with the above-mentioned mixing ratio. increases to In addition, for example, if component (B) is omitted, the extinguishing time is extended by about 4 to 7 times compared to the composite chemical extinguishing agent of the present invention, as shown in several examples later in Comparative Example 1, and the extinguishing agent The amount used is about 2 to about 5 times larger, and the additive fire extinguishing effect of the composite chemical fire extinguisher of the present invention is lost. Furthermore, for example, if component (C) is omitted, the extinguishing time and amount of extinguishing agent used tend to be longer and increase, as shown in several examples later in Comparative Example 2. There is a problem of re-ignition, and the additive fire extinguishing effect of the composite chemical fire extinguisher of the present invention is lost. The composite chemical fire extinguishing agent of the present invention can achieve rapid and reliable fire extinguishing effect with a small amount of use, for example,
By spraying a small amount of about 100 to 200 g for 1 to 2 seconds, complete extinguishing without fear of re-ignition can be achieved instantaneously, making it possible to exhibit excellent extinguishing performance, especially in the initial stage of extinguishing. In addition, after spraying the required amount of fire extinguishing,
Because it occupies only about 5% of the volume of indoor air, there is no risk of suffocation, compared to conventional extinguishing agents that require a gas concentration of about 30 to 40%, such as carbon dioxide extinguishing agents. In addition, the extinguishing agent itself has extremely low toxicity [Underwriter's Laboratories standard...
No. 1 is extremely toxic, No. 6 is non-toxic, and in the 6-level toxicity classification, component (A) is No. 6, component (B) is No. 5A], and is colorless. It is transparent, has extremely high safety, and does not cause problems such as loss of visibility during fire extinguishing operations. Furthermore, when extinguishing a fire using conventional water foam or powder extinguishing agents, the extinguishing agent is not only applied to the source of the fire, but also to areas around the fire that have not been affected by the fire to prevent the spread of combustion. It is necessary to prevent fire from occurring, and contamination of rooms, equipment, fixtures, materials, and other objects that are not affected by the fire cannot be avoided. However, the composite chemical fire extinguisher of the present invention is colorless, odorless, and It is made of safe ingredients, and after being injected, it acts on the fire source in gaseous form, repeating the extinguishing action and self-regeneration action against the combustion chain reaction factors.It also has excellent electrical insulation properties, so it has the characteristics of In addition to being free from the contamination problems associated with conventional fire extinguishing agents, it also has the advantage of exhibiting extinguishing action and effectiveness without having to apply the agent directly to the source of the fire.
For example, it has the unique feature of being able to reliably penetrate into the inside of a complex structure such as a computer and exerting its fire extinguishing effect. It has the advantage that it can be safely used as a fire extinguisher not only for related facilities, electronic equipment facilities, electrical control facilities, art museums, libraries, museums, etc., but also for important cultural properties and their facilities that are subject to contamination problems. Furthermore, the composite chemical fire extinguishing agent of the present invention can be effectively used against various types of fires such as general fires, oil fires, and electrical fires, and has the excellent feature of being free from restrictions depending on the target of the fire. . For example, an example of a comparison test between the composite chemical extinguishing agent of the present invention and a conventional carbon dioxide gas-generating extinguishing agent for a gasoline fire (gasoline amount: 6) is shown in Table A below.
