The present invention relates to an aqueous film-forming foam fire extinguishing agent, and more particularly to an aqueous film-forming foam fire extinguishing agent comprising a mixture of fluorine-based and silicon-based surfactant compounds of limited structure. Aqueous film-forming foam fire extinguishing agents made of surface-active compounds with perfluoroalkyl groups are water bubbles and their return water that spreads well over petroleum fuels, effectively extinguishes the fire, and
It is attracting attention because it can prevent re-ignition. The inventors of the present invention conducted studies to obtain a water-forming foam fire extinguishing agent with higher performance, and found that there are limited fluorine-based surfactant compounds that provide most of the properties necessary for a water-forming foam fire extinguishing agent. It has been found that an amine surface-active compound containing a perfluoroalkyl group has an excellent structure. However, such compounds cannot reduce the interfacial tension between water and oil, and foam extinguishing agents made of such compounds therefore do not have a sufficient rate of spreading of the water film on the oil surface, especially when the oil surface is ignited again. I learned that the drawback is that it has a weak ability to prevent the spread of fire. As a result of intensive research into water-forming foam fire extinguishing agents that do not have the above-mentioned drawbacks, the present inventors discovered that perfluoroalkyl group-containing amine surfactant compounds having a specific structure and silicone surfactant compounds having a specific structure. The inventors have discovered that a fire extinguishing agent containing the following within a specific range is extremely superior in terms of extinguishing ability, re-ignition prevention ability, foam heat resistance, and foaming power, and has thus completed the present invention. be. That is, the present invention has the following general formula: [However, R f represents a fluoroalkyl group having 4 to 12 carbon atoms.

大となつた。It is synthesized by changing the concentration of [Formula], an alkyl halide such as haloalkanesulfonate, haloalkane carboxylate, and haloalkane phosphate, or a cyclic compound such as propane sultone and γ-butyrolactone, and the alkali concentration of the catalyst or the molar ratio of the two. On the other hand, the silicon-based surface-active compound represented by the general formula () is preferably the silicon-based surface-active compound described in Japanese Patent Publication No. 47-21080, and particularly the following compounds may be mentioned. The blending ratio of the perfluoroalkyl-containing amine surfactant compound and the silicone surfactant compound according to the present invention is 5 to 24 parts, preferably 7 to 20 parts of the latter per 100 parts of the former. When the silicone-based surfactant compound is 5 parts or less, the extinguishing agent made of the silicone surface-active compound is insufficient in the ease with which a water film can be spread. On the other hand, if the amount is more than 24 parts, the extinguishing agent made of it is disadvantageous because the thermal stability of the foam is insufficient. The concentration of the mixture of surface-active compounds in the firefighting foam will vary depending on the concentration at which the foam is used, but is preferably between 1 and 20% by weight. In addition to this, various additives can be added to the fire extinguishing foam for various purposes. For example, foam stabilizers, freezing point depressants,
Examples include rust preventives and buffering agents. Foam stabilizers are mainly added to adjust expansion ratio or drainage, and include polyethylene glycol, polyvinyl alcohol, polyvinylpyrrolidone, carboxymethyl cellulose, gum arabic, sodium alginate, polypropylene glycol, polyvinyl resin, and the like. Examples of freezing point depressants include ethylene glycol, propylene glycol, cellosolves (ethyl cellosolve, butyl cellosolve), carbitols (ethyl carbitol, butyl carbitol), lower alcohols (isopropyl alcohol, butanol), and urea. Various rust preventives and buffers known in the industry can be used. The aqueous film-formed fire extinguishing foam of the present invention is applied in a known manner, i.e. by blowing or admixing with air, carbon dioxide, nitrogen gas, low boiling fluorocarbons such as difluorodichloromethane, or other suitable non-flammable gases. Ru. The water-forming foam fire extinguishing agent of the present invention is diluted with water at an appropriate ratio (for example, 16.7 times, 33.3 times, etc.), and the pH is reduced to 6.
Water (for example, fire extinguishing water, underground water, tap water, or seawater) is used after adjusting the water to ~8.
Generally, it is diluted to the working concentration, stored, and applied. It can also be stored as a concentrated undiluted solution, and when used, the dilution level can be adjusted using the usual method, for example, by sucking the concentrated undiluted solution into a water stream on the way to a fire extinguisher or foam nozzle, and then blowing or mixing with a nonflammable gas such as air. It can also be applied by emitting or sending the foam from above or below the fire surface. The aqueous film-forming foam fire extinguishing agent of the present invention includes sodium bicarbonate,
It can also be used in combination with powder fire extinguishers, protein foam fire extinguishers, foam fire extinguishers for wood fires, etc. containing potassium bicarbonate, magnesium bicarbonate, ammonium sulfate, ammonium phosphate, calcium carbonate, etc. as ingredients. Next, the present invention will be explained in more detail with reference to Examples, in which all percentages represent weight percentages. Examples 1 and 2, Comparative Example 1 5 g of -1 as a fluorosurfactant compound,
0.8g of -1 as a silicone surfactant compound
Next, 23 g of butyl carbitol as a freezing point depressant and 18.5 g of polyethylene glycol (average molecular weight 4000) as a foam stabilizer were added, the volume was made up to 100 g with ion-exchanged water, a fire extinguishing agent was added, and the pH was adjusted with hydrochloric acid. Adjusted to 7.4. Table 1 shows the results of diluting 3% of this drug with tap water and seawater and measuring the surface tension using the Wilhelmi method at 23°C and the interfacial tension against cyclohexane using the droplet weight method at 20°C. Both interfacial tension and surface tension were lower, and the diffusion coefficient was also larger than when -1 was not blended (Comparative Example 1).

ばめ、自動的に消火することが判つた。[Table] Examples 3, 4, 5, Comparative Examples 2, 3 -1 4.4g as a fluorine-based surfactant compound,
and -6 0.4g, -1 0.4g added as a silicone surfactant compound, butyl carbitol 23g, polyethylene glycol (MW4000)
18.5g was added, the total volume was made up to 100g with ion-exchanged water, a fire extinguishing agent was added, and the pH was adjusted to 7.4 with hydrochloric acid. Next, the following operations were performed to check the spreadability of water film formation and the heat resistance of bubbles. Dilute 3% of this drug with tap water and seawater, respectively. Take 100ml and put it in a high speed blender mixer and whisk for 20 seconds. Meanwhile, place 100 ml of n-hexane in a stainless steel circular plate with a diameter of 155 mm and a height of 90 mm, and keep the temperature constant at 20°C. Place the foam above on top of the oil and leave it for 17 minutes. Next, cover it with a cylinder with a diameter of 60 mm, and carefully remove the drug inside the cylinder with a spoon. The oil surface was then ignited and after burning for 30 seconds, the cylinder was removed. Table 2 shows the results of how the flame changed over time after the cylinder was removed. Examples 6, 7, 8, Comparative Examples 4, 5, 6 -2, -3, -4 in place of -1, and -3, -4, - in place of -6 as fluorine-based surfactant compounds Example 5 was carried out in the same manner as in Examples 3, 4, and 5, using -2 instead of -1 as the silicon-based surfactant compound, and the same tests were conducted. The results are listed in Table 3 along with Comparative Examples 4, 5, and 6. It has been found that the aqueous film formation of the fire extinguishing agent of the present invention compresses the flame and automatically extinguishes it.
