い。2. Description of the Related Art Generally, fire is extinguished by cooling action by water, but various chemical substances are added for the purpose of improving the extinguishing efficiency by water. Fire-extinguishing liquids are classified into those that extinguish wood fires (A fires or ordinary fires stipulated by the Fire Service Act) and oil fires (B fires or fires involving combustible solids and combustible liquids). There is. Those that respond to these AB fires are called strengthening liquids and must pass the specified standards.

った。The most common extinguishing solution is potassium carbonate, 4
A 0% concentrated aqueous solution is used, which has a pH of 12
Since it has a strong alkalinity of -13, it is not preferable to store it in a metal container for a long time from the viewpoint of corrosion of the container. Further, when this fire extinguishing liquid adheres to a human body or clothes, it damages the skin and fibers, and particularly when it gets into the eyes during the fire extinguishing work, it is necessary to wash the eyes promptly, which makes the handling extremely difficult.

が困難であるという問題点もあった。On the other hand, it is known that boric acid and other boron compounds act as flame retardants, but in particular boric acid has a low dissolution rate in water and a low solubility (about 4% by weight at 20 ° C.). Therefore, there was not enough fire extinguishing liquid. In addition, since the aqueous solution of boric acid is slightly acidic (pH about 5.2), it is difficult to store it in a metal container for a long period of time.

The amount of hydroxyalkylamine used is 0.2 to 5 parts by weight, more preferably 0.5 to 5 parts by weight per 1 part by weight of orthoboric acid.
2 parts by weight is preferred. If the amount of hydroxyalkylamine used is less than the above range, the solubility of orthoboric acid is reduced, and a uniform solution may not be obtained, which is not preferable. On the contrary, when the amount of hydroxyalkylamine used exceeds the above range, the effect of hydroxyalkylamine does not increase any more, and an expensive chemical is unnecessarily used, which is not preferable.

になるので好ましくない。When the fire extinguishing solution of the present invention contains a urea derivative such as urea or thiourea, not only the urea derivative itself has a flame retarding effect but also the effect of remarkably lowering the freezing point of the solution. The amount of urea derivative used is orthoboric acid 1
The amount is preferably 0.2 to 5 parts by weight, more preferably 0.5 to 2 parts by weight. If the amount of the urea derivative used is less than the above range, the effect of lowering the freezing point may not be sufficiently exhibited, which is not preferable. On the contrary, when the amount of the urea derivative used exceeds the above range, the effect of the urea derivative does not increase any more, and an expensive chemical is unnecessarily used, which is not preferable.
【００１０】本発明において、消火液のｐＨは、中性に

用が優れた消火作用を発揮するものと思われる。The fire-extinguishing liquid of the present invention has a remarkable fire-extinguishing ability as compared with the case where a single aqueous solution is simply used. The reason for this is that the orthoboric acid has a unique flame retardant effect on wood, etc., and the spreading and penetrating properties of the above chemical components on wood are superior to water alone, and their synergistic effect exerts an excellent fire extinguishing effect. It seems to do.
