The present invention relates to a fire extinguishing agent that is used as a fire extinguishing agent that enhances the fire extinguishing effect by mixing it into waterproof fire extinguishing water for fire brigade and the like at a ratio of about several percent. In general, it is said that the amount of water sprayed per 1 m2 of area where the fire spreads is approximately 1.5 tons.
In buildings such as condominiums, households located on the floors below are experiencing significant water damage.
In recent years, we have reached a situation where water damage exceeds fire damage. Therefore, in order to minimize water damage, it is being considered to mix special fire extinguishing agents into water to increase the fire extinguishing effect using as little water as possible. As such extinguishing agents, alkali metal salts are known that have a negative catalytic effect that inhibits the chain reaction of combustion during a fire, and also have a disaster prevention effect.For example, about 35% by weight of potassium carbonate
There is a strong liquid fire extinguishing agent for small fire extinguishers that has K 2 CO 3 dissolved in water. Therefore, it is possible to mix this strong liquid fire extinguishing agent into water at a ratio of several percent as a raw solution and spray it with water, but since the proportion of potassium carbonate in the fire extinguishing water is too small, it is difficult to spray water alone. In comparison, the fire extinguishing effect is not that great. On the other hand, if a fluorine-based surfactant can be mixed into the above-mentioned aqueous solution of high concentration of potassium carbonate, the diffusion and permeability of the liquid will be increased to wet the combustion surface well, and the chemical action of the halogen will also be added to enhance the fire extinguishing effect. However, if a fluorine-containing surfactant is simply added to a highly concentrated potassium carbonate aqueous solution, the surfactant will precipitate due to a salting-out phenomenon and will not dissolve. Therefore, a fire extinguishing agent has been proposed in which a fluorine-based surfactant is dissolved in an aqueous potassium carbonate solution by adding about 2% by weight of a fluorine-based compound such as perfluoroalkyl sulfonate or perfluoroalkyl carbonate ( (Japanese Patent Application Publication No. 51-150900). However, even if this fire extinguishing agent dissolves the fluorine-based surfactant by adding a fluorine-based compound such as perfluoroalkyl sulfonate, the proportion of potassium carbonate in the solution is as small as about 3% by weight.
Even if a few percent of such fire extinguishing agent is mixed with water and water is sprayed, no fire extinguishing effect can be expected to reduce water damage. Furthermore, it is possible to use a undiluted extinguishing agent containing a large amount of alkali metal salts such as carbonic acid or phosphoric acid, or inorganic salts such as alum or alkali silicate; In order to achieve this, it is necessary to mix the alkali metal salts and inorganic salts in an amount exceeding the dissolution saturation range, and insoluble components are precipitated in the extinguishing solution, resulting in a stable extinguishing agent solution for suppressing water damage. The situation is that it is not possible to obtain. Incidentally, in recent years, fluorine-based surfactants having a fluoroalkyl group and a water-soluble group have been developed as additives for fire extinguishing foam (Japanese Patent Application Laid-Open No. 1983-1999).
52768) and is commercially available as Unidyne DS-301 (registered trademark). Therefore, the inventors of the present application have developed the Unidyne DS-301
After repeated numerous experiments, we focused on whether it was possible to create a stock solution of fire extinguishing agent for water damage control that contained a water-soluble polymeric surfactant known as potassium carbonate. Adding urea (NH 2 ) 2 CO, which has an extinguishing effect on A fires (general fires) and is also known to lower freezing temperatures,
Furthermore, propylene glycol, 3-methyl-3-
By using methoxybutanol and ethylene glycol monobutyether as solvents, we succeeded in completely dissolving a water-soluble polymeric surfactant having a fluoroalkyl group and a water-soluble group in an aqueous potassium carbonate solution, and completed the present invention. This is what I did. That is, in the present invention, propylene glycol, 3-methyl-
A water-soluble polymeric surfactant having a fluoroalkyl group and a water-soluble group is mixed through each of 3-methoxybutanol and ethylene glycol monobutyl ether, or each of propylene glycol and 3-methyl-3-methoxybutanol. The main point is to use extinguishing agents that have been completely dissolved. More specifically, in the present invention, the proportion of potassium carbonate K 2 CO 3 in the whole solution is 10% by weight.
or more, and the total proportion of potassium carbonate K 2 CO 3 and urea (NH 2 ) 2 CO is 20% by weight or more,
The total proportion of both is about 30% by weight at most, which sufficiently increases the fire extinguishing effect when diluted with water. In addition, a water-soluble polymeric surfactant (Unidyne DS - 301) having 1 to 3% by weight of a fluoroalkyl group and a water-soluble group is added to the above aqueous solution of potassium carbonate K 2 CO 3 and urea (NH 2 ) 2 CO.

It is a water-soluble polymer compound with an average molecular weight of 5000 or more that does not exceed 50 dyn/cm at 25℃, and is used as a foam fire extinguisher, especially for water-soluble flammable liquids such as alcohols, ketones, and ester aldehydes. It has been developed as an additive to reduce the solubility of foam and form stable foam. The polymer compound having a fluoroalkyl group and a water-soluble group accounts for 50% by weight, and the remaining 50% by weight is occupied by a solvent such as isopropyl alcohol. Next, the present invention will be explained in detail with reference to Examples.

[Table] The liquid mixture of Example 5 also showed the same properties as the liquid mixtures of Examples 1 to 4. The fire extinguishing agent of the present invention obtained in Examples 1 to 5 was
When using a ~6% Premix aqueous solution and spraying water on a wooden fire model in the form of a stick or spray, it was found that the fire extinguishing performance was improved several times compared to simply spraying water.
Moreover, the effect of suppressing flare-up was confirmed. Next, the uses of the fire extinguishing agent of the present invention will be explained. The extinguishing agent clarified in the above explanation is stored in a tank etc. as an extinguishing stock solution, and when used, it is mixed with water pumped by a pressurized water supply device using a mixer to mix 3 to 6%.
Mix at the following ratio and spray water from the water spray nozzle. In this case, the amount of water required per square meter of fire spread area can be significantly reduced by mixing the extinguishing agent of the present invention, so the diameter of the fire nozzle used by the fire brigade should be made smaller to reduce the amount of water sprayed. . As a result, the amount of water required to achieve the same fire extinguishing effect as before is significantly reduced, and water damage to buildings or household goods can be significantly reduced without impairing the fire extinguishing ability. Another method of using the fire extinguishing agent of the present invention is to mix the fire extinguishing agent into fire extinguishing water using a water-based fire extinguishing system in a building. Therefore, water loss can be suppressed by making fire hydrant nozzles, sprinkler heads, and water spray heads smaller and smaller in flow rate, thereby reducing the size of water supply devices and piping equipment, which also results in a reduction in equipment costs. Furthermore, for general household use, there is a method of mixing the extinguishing agent of the present invention with water and spraying it on the fire source in the event of a fire, or diluting the extinguishing agent of the present invention several times, or using it as an extinguishing agent of a small fire extinguisher or an automatic fire extinguisher. It is also possible to use it as
