Description

本発明は、消火器、消火装置又は消火設備等に用いる消火剤に関する。   The present invention relates to a fire extinguisher used for a fire extinguisher, a fire extinguisher or a fire extinguishing facility.

一般的な水系消火剤として、強化液消火剤(濃度35〜40体積%の炭酸カリウム水溶液)がある。これはA火災(普通火災)、B火災(油火災)及びC火災(電気火災)に有効で、特に天ぷら油火災の消火に優れているが、pHが12〜13の強アルカリ性であるため取り扱いに注意を要する。
強化液消火剤を含む従来の消火剤は、含有成分の人体に対する安全性が確保されていないため、飲食料品やそのパッケージ等のように、直接又は間接的に口に入れるものを扱う場所で火災発生又は誤操作等により消火剤を放出した際に、消火剤が付着したものは洗浄又は廃棄する必要がある。すなわち、消火剤成分の人体に対する安全性が確保されていないことで、火災で直接的な被害を受けたもの以外に消火剤が付着することで二次被害が生じるため、これを少なくすることが求められている。
As a general water-based fire extinguishing agent, there is a strengthening liquid fire extinguishing agent (a potassium carbonate aqueous solution having a concentration of 35 to 40% by volume). This is effective for A fire (ordinary fire), B fire (oil fire) and C fire (electric fire). It excels especially in extinguishing tempura oil fires, but it is highly alkaline with a pH of 12-13, so it is handled. Need attention.
Conventional fire extinguishing agents, including fortified liquid fire extinguishing agents, do not ensure the safety of the components contained in the human body. When a fire extinguishing agent is released due to a fire or erroneous operation, it is necessary to wash or dispose of the fire extinguishing agent. In other words, since the safety of the fire extinguishing agent components to the human body has not been ensured, secondary damage will be caused by the attachment of fire extinguishing agents to those other than those directly damaged by fire. It has been demanded.

特許文献1には、全体量100ミリリットル中に、カルボン酸アルカリ金属塩を20〜55g、天然界面活性剤を0.10〜2.0gの割合で含有し、カルボン酸アルカリ金属塩と天然界面活性剤との含有量の比が、質量比で、カルボン酸アルカリ金属塩:天然界面活性剤=30:1〜100:1である消火剤が開示されている。
特許文献1によれば、高い消火性能と、人体に対する高い安全性の両方を備えた消火剤を得ることができる。
Patent Document 1 discloses that an alkali metal carboxylate and a natural surface active agent each contain 20 to 55 g of an alkali metal carboxylate and 0.10 to 2.0 g of a natural surfactant in a total amount of 100 ml. There is disclosed a fire extinguisher in which the content ratio with the agent is, in terms of mass ratio, alkali metal carboxylate: natural surfactant = 30: 1 to 100: 1.
According to Patent Literature 1, a fire extinguishing agent having both high fire extinguishing performance and high safety for a human body can be obtained.

特開2009−291257号公報JP 2009-291257 A

天然界面活性剤は高価であることから、わずかでも使用量を減らすことで大きなコストメリットが得られる。しかし、天然界面活性剤は発泡して被消火物の表面を覆う効果を有するため、天然界面活性剤の使用量を減らすと消火性能が低下してしまう。
特許文献1には、カルボン酸アルカリ金属塩と天然界面活性剤との含有量の比率等にもよるが、全体量100ミリリットル中に、天然界面活性剤が1〜2gの割合で混合されているときには、A火災、B火災及び天ぷら油火災のいずれに対しても消火性能が「○」となり、特に有効であることが示されている(実施例6−3、6−4、10−3、10−4等)。一方で、全体量100ミリリットル中に、天然界面活性剤が0.05〜0.20gの割合で混合されているときには、A火災、B火災及び天ぷら油火災に対する消火性能のうちの少なくとも一つが「△」又は「×」となることが示されている(実施例6−1、6−2、10−1、10−2等)。
Since natural surfactants are expensive, significant cost benefits can be obtained by reducing the amount used even slightly. However, since the natural surfactant foams and has an effect of covering the surface of the fire extinguishing object, the fire extinguishing performance is reduced when the amount of the natural surfactant used is reduced.
In Patent Document 1, depending on the content ratio of the alkali metal carboxylate and the natural surfactant, etc., the natural surfactant is mixed at a ratio of 1 to 2 g in a total amount of 100 ml. At times, the fire extinguishing performance was “○” for any of A fire, B fire and tempura oil fire, indicating that the fire extinguishing effect was particularly effective (Examples 6-3, 6-4, 10-3, 10-4). On the other hand, when the natural surfactant is mixed at a ratio of 0.05 to 0.20 g in a total volume of 100 ml, at least one of the fire extinguishing performances against A fire, B fire and tempura oil fire is “ Δ ”or“ X ”(Examples 6-1, 6-2, 10-1, 10-2, etc.).

そこで本発明は、高い消火性能と人体に対する高い安全性の両方を備えつつ、更に天然界面活性剤の使用量が少ない消火剤を提供することを目的とする。   Therefore, an object of the present invention is to provide a fire extinguisher that uses both a natural fire-extinguishing agent and a small amount of a natural surfactant while providing both high fire-extinguishing performance and high safety for the human body.

本発明の第1の実施の形態による消火剤は、酢酸カリウム、クエン酸カリウム、酢酸ナトリウム、及びクエン酸ナトリウムから選択された1又は2以上からなるカルボン酸アルカリ金属塩と、レシチン、サポニン、及びカゼインから選択された1又は2以上からなる天然界面活性剤と、水と、で構成され、全体量100ミリリットル中に、カルボン酸アルカリ金属塩を30〜55g、天然界面活性剤を0.107〜0.200gの割合で含有し、カルボン酸アルカリ金属塩と天然界面活性剤との含有量の比が、質量比で、カルボン酸アルカリ金属塩:天然界面活性剤=150:1〜275:1である。
本実施の形態によれば、高い消火性能と人体に対する高い安全性の両方を備えつつ、更に天然界面活性剤の使用量が少ない消火剤を提供できる。
The fire extinguishing agent according to the first embodiment of the present invention includes an alkali metal carboxylate salt of one or more selected from potassium acetate, potassium citrate, sodium acetate, and sodium citrate, lecithin, saponin, and A natural surfactant consisting of one or more selected from casein and water, and a total amount of 100 ml, 30 to 55 g of an alkali metal carboxylate and 0.107 to 0.1 g of a natural surfactant. 0.200 g, and the content ratio of the alkali metal carboxylate to the natural surfactant is expressed as a mass ratio of alkali metal carboxylate: natural surfactant = 150: 1 to 275: 1. is there.
According to the present embodiment, it is possible to provide a fire extinguishing agent that has both a high fire-extinguishing performance and a high safety to a human body, and further uses a small amount of a natural surfactant.

カルボン酸アルカリ金属塩は、A火災(普通火災)と天ぷら油火災の消火に有効な成分である。天然界面活性剤は、発泡して被消火物の表面を覆うことによりB火災(油火災)の可燃性ガスの蒸発拡散を抑える効果がある。よって、本実施の形態によれば、A火災(普通火災)、B火災(油火災)、天ぷら油火災のいずれの火災に対しても消火性能が高い消火剤を提供できる。なお、C火災(電気火災)用消火器は、消火剤成分の飛ばし方が他の火災用消火器と異なるだけであるため、本実施形態の消火剤はC火災(電気火災)用としても高い消火性能を有する。   The alkali metal carboxylate is an effective component for extinguishing A fire (ordinary fire) and tempura oil fire. The natural surfactant has the effect of suppressing the evaporation and diffusion of the combustible gas of fire B (oil fire) by foaming and covering the surface of the fire extinguishing object. Therefore, according to the present embodiment, it is possible to provide a fire extinguishing agent having high fire extinguishing performance against any of A fire (ordinary fire), B fire (oil fire), and tempura oil fire. Note that the fire extinguisher for C fire (electric fire) is different from other fire extinguishers only in how the fire extinguisher components fly, so the fire extinguisher of the present embodiment is also high for C fire (electric fire). Has fire extinguishing performance.

また、カルボン酸アルカリ金属塩のうち、クエン酸カリウム、酢酸ナトリウム、及びクエン酸ナトリウムは、日本で食品添加物として認められている成分である。酢酸カリウムはFAO(国連の食料農業機関)及びWHO(世界保健機構)下のJECFA(合同食品添加物専門家会議)による安全評価試験の結果、人体に対する安全性が確認されている成分であり、EU諸国では食品添加物として使用されている。
レシチン、サポニン、及びカゼインは日本で食品添加物として認められている成分である。
したがって、本実施形態の消火剤は人体に対する高い安全性が確保されている。
また、本実施形態の消火剤は、必要に応じて添加剤を添加してよいが、その添加剤は食品添加物に指定されている成分とする。
Further, among the alkali metal salts of carboxylic acids, potassium citrate, sodium acetate, and sodium citrate are components recognized as food additives in Japan. Potassium acetate is a component that has been confirmed to be safe for the human body as a result of safety evaluation tests conducted by FAO (United Nations Food and Agriculture Organization) and JECFA (Joint Food Additive Experts) under the World Health Organization (WHO). It is used as a food additive in EU countries.
