。According to Ministry of Home Affairs Ordinance No. 26 of 1975, "Technical Standards for Foam Fire Extinguishing Agents," fire extinguishing foams are broadly classified into sputum foam fire extinguishing agents, synthetic surfactant foam fire extinguishing agents, and water-forming foam fire extinguishing agents. be done. Among these, sputum foam extinguishing agents exhibit excellent fire resistance and oil resistance against burning oil fires, but the fluidity of the foam is poor and extinguishing is slow. In addition, synthetic surfactant foam fire extinguishing agents are
Although it has excellent fluidity, it has poor fire resistance and oil resistance, and after extinguishing the fire, the foam disappears and the oil surface is exposed, creating a risk of re-ignition. Furthermore, while aqueous film-forming foam fire extinguishing agents have excellent fluidity and better oil resistance than synthetic surfactant foam fire extinguishing agents, the foam is easily blown away by the wind over time, exposing the oil surface. When the temperature rises, water loses its ability to form a film and starts to ignite again.

、何れも耐油性や再燃耐火性になお問題を残している。In connection with the above point, Japanese Patent Application Laid-Open No. 59-37960 discloses a method for strengthening foam fire extinguishing agents, which increases the fire extinguishing effect by adding a fluorine-based surfactant to the foam fire extinguishing agent depending on the fire. JP-A-59-88167 discloses that a water-soluble polymer compound is mixed with a foam fire extinguishing agent and foamed to improve the foamability, water retention, and adhesion of the foam fire extinguishing agent. Although fire extinguishing methods have been disclosed, there are still problems with oil resistance and rekindling fire resistance.

すればよい。For super absorbent resin slurry, for example, JP-A-582007
As disclosed in JP-A No. 58, JP-A-62-044271, JP-A-63-092364, etc.
A known slurry made by slurrying a superabsorbent resin with an organic dispersion medium and adding a fire extinguishing power improver, a dispersion stabilizer, etc. as necessary can be used. For example, starch-(meth)acrylonitrile graft 1 [
Known products such as saponified starch, cross-linked starch-(meth)acrylic acid (salt) copolymer, cross-linked polyacrylate, cross-linked polyvinyl alcohol, polyvinyl alcohol-acrylate block copolymer, and water absorption capacity ( (weight after water absorption/weight before water absorption) is preferably 200 or more, particularly preferably 400 or more. Further, as the organic dispersion medium, for example, methanol, ethanol, ethylene glycol, glycerin, propylene glycol, liquid paraffin, mineral oil, naphthenic acid, etc. can be selected depending on the type of superabsorbent resin, and usually, About 1 to 10 parts by weight may be used per 1 part by weight of the super absorbent resin.
泡消火薬剤水溶液への高吸水性樹脂スラリーの添加量は
、スラリーの組成や泡消火薬剤の種類、火災の種類等に
依存するが、通常、高吸水性樹脂成分が泡消火薬剤水溶
液中に０．０５〜１．０重寸％程度混入されるように：
Ａ整すればよい。The amount of superabsorbent resin slurry added to the aqueous foam fire extinguishing agent solution depends on the composition of the slurry, the type of foam fire extinguishing agent, the type of fire, etc., but usually, the amount of super absorbent resin slurry added to the foam fire extinguishing agent aqueous solution is 0. To be mixed in about .05~1.0% by weight:
All you have to do is adjust A.
高吸水性樹脂は、水と接触すると直ちにその水を吸収し

ることが知られている。When super absorbent resin comes into contact with water, it immediately absorbs the water and turns into kelp, so when it is added to an aqueous extinguishing agent and released, it has an excellent cooling and suffocating effect against fires, and especially It is known that when it is used in the form of a slurry, gelation is delayed until the extinguishing agent aqueous solution reaches the fire point due to the presence of an organic solvent, which prevents blockages in the water nozzle. There is.
本発明における高吸水性樹脂スラリーは、泡消火薬剤水
溶液にその発泡中及び／又は発泡後に添加されるので、
泡消火薬剤の水溶液自体とではなく、発生した泡と主と

。従って、ゲル化は泡が火点に到達した後も徐々に進行
し、火災に対して泡及びゲルの各冷却作用及び窒息作用
が相乗的、相互補完的に比較的長時間にわたって働くこ
とになる。Since the superabsorbent resin slurry in the present invention is added to the aqueous foam fire extinguishing agent solution during and/or after foaming,
It mainly comes into contact with the generated foam, rather than with the aqueous solution of the foam fire extinguishing agent itself, and is mixed with it and sprayed onto the flash point. Therefore, gelation progresses gradually even after the foam reaches the fire point, and the cooling and suffocating effects of the foam and gel act synergistically and mutually complementary against the fire over a relatively long period of time. .
なお、高吸水性樹脂スラリーを泡消火薬剤水溶液の発泡
前に添加した場合は、発泡工程における空気等の混入に
よって高吸水性樹脂スラリーか泡消火薬剤水溶液自体と
攪拌混合されると共にケル化が急激に進み、発泡及び泡
の噴射が困難になる。In addition, if the superabsorbent resin slurry is added to the aqueous foam extinguishing agent solution before foaming, the superabsorbent resin slurry or the aqueous foam extinguishing agent solution will be stirred and mixed with the aqueous foam extinguishing agent solution itself due to the introduction of air during the foaming process, and rapid kelization will occur. This progresses to the point where foaming and foam injection becomes difficult.

表２に示す試験結果によれば、本発明例は比較例に比べ
て風による泡の耐飛散性に優れていることかわかる。According to the test results shown in Table 2, it can be seen that the examples of the present invention are superior to the comparative examples in terms of foam scattering resistance due to wind.

．． When the light was emitted toward a board (0.35 m2) measuring 5 m x 0.7 m in width and the weight of the foam attached to the board was measured, it was 200 g for the foam of Comparative Example 1, whereas it was 200 g for the foam of Comparative Example 1.
In the case of the foam, it weighs 290g, and it can be seen that the latter has better foam adhesion than the former.
