Description
本発明は、2剤混合型の消火剤において、過酸化水素をカタラーゼという分解酵素で泡をつくり、その泡をクリーミーな強いものにして火元を覆って消火する2剤混合型の消火剤に関する。 The present invention relates to a two-component mixed fire extinguisher that forms bubbles with hydrogen peroxide as a degrading enzyme called catalase, and makes the bubbles strong and creamy to cover the fire and extinguish the fire. .
従来の消火剤は、炎焼しつつある油の表面全面を、界面活性剤と脂肪酸塩等を含む難燃性で粘性の大きい被膜の炭酸ガスによる泡とで覆い、所謂窒息効果を発現し当該油表面への酸素(空気)の供給を遮断させて所謂窒息状態とすることによって、炎焼しつつある油を鎮火、消火させるように構成されている(特許文献1)。 Conventional fire extinguishing agents cover the entire surface of oil that is being flame-fired with bubbles of carbon dioxide in a flame-retardant and highly viscous coating containing a surfactant and fatty acid salts, etc. It is configured to extinguish and extinguish the flame-burning oil by shutting off the supply of oxygen (air) to the oil surface to create a so-called suffocation state (Patent Document 1).
しかしこの消火剤は、消火を炭酸ガスによる泡に求めるため、炭酸ガス発生の原因となる脂肪酸塩の熱分解のしやすさ等が影響した。 However, since this fire extinguisher demands fire extinguishing with bubbles of carbon dioxide, the ease of thermal decomposition of the fatty acid salt that causes carbon dioxide generation was affected.
本発明の目的は、脂肪酸塩の熱分解のしやすさ等に影響されずに、消火することができ、人体にも無害である消火剤を提供することころにある。 An object of the present invention is to provide a fire extinguishing agent that can be extinguished without being affected by the ease of thermal decomposition of a fatty acid salt, and is harmless to the human body.
本発明は、A成分とB成分とを混合し発生した泡により火元を覆って消火する2剤混合型の消火剤であって、
A成分に過酸化水素水と界面活性剤と油剤と水とを含み、
B成分にカタラーゼを含む溶液又は粉末を含む、
2剤混合型の消化剤である。
The present invention is a two-component mixed fire extinguisher that covers and extinguishes the fire with foam generated by mixing the A component and the B component,
A component contains hydrogen peroxide, surfactant, oil and water,
A solution or powder containing catalase in component B,
It is a two-agent mixed digestive agent.
本発明により、消火時、A成分とB成分を混合することにより、過酸化水素をカタラーゼという分解酵素で泡をつくり、その泡をクリーミーな強いものにして火元を覆って消火することができる。 According to the present invention, at the time of fire extinguishing, by mixing the A component and the B component, hydrogen peroxide can be made a foam with a degrading enzyme called catalase, and the foam can be made strong and creamy to cover the fire source and extinguish. .
A成分とB成分を混合することで泡を発生させるには、過酸化水素とカタラーゼを用いる。A成分に過酸化水素水と界面活性剤と油剤と水を含み、B成分にカタラーゼを含む水溶液又は粉末を含む。ただ消火するには強い泡の膜とし、その強い泡の膜で覆わなければならない。
強い泡の膜にする成分としては、過酸化水素水に油剤と界面活性剤と水を加えた成分とし、好ましくは安定剤を加える。
Hydrogen peroxide and catalase are used to generate bubbles by mixing the A component and the B component. A component contains hydrogen peroxide, surfactant, oil and water, and B component contains an aqueous solution or powder containing catalase. To extinguish the fire, it must be made of a strong foam film and covered with the strong foam film.
The component for forming a strong foam film is a component obtained by adding an oil agent, a surfactant and water to hydrogen peroxide, and preferably a stabilizer.
油剤としては油脂類、ロウ類、炭化水素類、高級アルコール類、脂肪酸、エステル類が用いられる。油脂類はミンク油等の動物油、オリブ油、ヤシ油等の植物油、カルナウバロウ等のロウ油、流動パラフィン、パラフィン等の炭化水素類、ミリスチルアルコール、セタノール、ステアリルアルコール、セトステアリルアルコール等の高級アルコール、ラウリン酸、ミリスチン酸、パルミチン酸、オレイン酸等の脂肪酸、ミリスチン酸オクチルドデシル、乳酸セチル、トリミリスチン酸グリセリン等のエステル類が用いられる。これらは1種又は2種以上用いられる。 As the oil, fats and oils, waxes, hydrocarbons, higher alcohols, fatty acids and esters are used. Fats and oils include animal oils such as mink oil, vegetable oils such as olive oil and coconut oil, wax oils such as carnauba wax, hydrocarbons such as liquid paraffin and paraffin, higher alcohols such as myristyl alcohol, cetanol, stearyl alcohol, cetostearyl alcohol, Fatty acids such as lauric acid, myristic acid, palmitic acid and oleic acid, and esters such as octyldodecyl myristate, cetyl lactate and glyceryl trimyristate are used. These are used alone or in combination of two or more.
界面活性剤としては、ラウリン酸ナトリウム、ラウリル硫酸ナトリウム、ポリオキシエチレンラウリル硫酸ナトリウム、テトラデセンスルフォン酸ナトリウム等の陰イオン性界面活性剤、塩化ステアリルトリメチルアンモニウム、塩化ジステアリルジメチルアンモニウム、ステアリン酸ジメチルアミノプロピルアミド等の陽イオン界面活性剤、2-アルキル-N-カルボキシメチル-N-ヒドロキシエチルイミダゾリウムベタイン、ラウリルジメチルアミノ酢酸ベタイン、ヤシ油脂肪酸アミドプロピルベタイン等の両イオン界面活性剤、ポリオキシエチレンセチルエーテル、ポリオキシエチレンポリオキシプロピレングリコール、グリセリン脂肪酸エステル、ポリグリセリン脂肪酸エステル、ポリオキシエチレン多価アルコール脂肪酸エステル等の非イオン界面活性剤が1種又は2種以上用いられる。 Surfactants include anionic surfactants such as sodium laurate, sodium lauryl sulfate, sodium polyoxyethylene lauryl sulfate, sodium tetradesense sulfonate, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, dimethylamino stearate Cationic surfactants such as propylamide, zwitterionic surfactants such as 2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolium betaine, lauryldimethylaminoacetic acid betaine, coconut oil fatty acid amidopropyl betaine, polyoxyethylene Such as cetyl ether, polyoxyethylene polyoxypropylene glycol, glycerin fatty acid ester, polyglycerin fatty acid ester, polyoxyethylene polyhydric alcohol fatty acid ester Ionic surface active agents are used singly or in combination.
安定剤としては、クエン酸、クエン酸ソーダ、リン酸、リン酸塩等のpH調整剤、エデト酸ナトリウム、ヒドロキシエタンジホスホン酸、ヒドロキシエタンジホスホン酸4ナトリウム等のキレート剤、パラベン、フェノキシエタノール等の防腐剤、その他、ジエチレングリコールモノエチルエーテル、グリセリン、1,3-ブチレングリコール等がある。 Stabilizers include pH adjusters such as citric acid, sodium citrate, phosphoric acid and phosphate, chelating agents such as sodium edetate, hydroxyethanediphosphonic acid, tetrasodium hydroxyethanediphosphonate, parabens, phenoxyethanol, etc. In addition, there are diethylene glycol monoethyl ether, glycerin, 1,3-butylene glycol and the like.

Higher alcohols, hydrocarbons such as liquid paraffin, and water are used. Further, chelating agents, particularly hydroxyethane diphosphonic acid tetrasodium and hydroxyethane diphosphonic acid are preferably used. In addition, it is desirable to use phenoxyethanol, diethylene glycol monoethyl ether, sodium citrate, citric acid, and phosphoric acid.
このように、A成分として過酸化水素水に油剤と界面活性剤と水を加えた成分とすることによって、B成分のカタラーゼを加えて混合物としても、混合組成物時点でより強いクリーミーな泡として火元を覆って消火することができる。 In this way, by adding an oil agent, a surfactant, and water to hydrogen peroxide water as the A component, even if the B component catalase is added as a mixture, it becomes a stronger creamy foam at the time of the mixing composition. Can cover the fire and extinguish it.

A component
B成分
次に、比較例1を基準として実施例1、2及び比較例2に対し泡のクリーミーさを相対評価した。
評価基準は次の通りである。○及び◎がこの消火剤として許容できる範囲である。
× :泡はできるがすぐに崩壊する。
△ :泡はできるが徐々に崩壊する。
○ :泡ができてかなりの時間保持しているが泡の表面が時間とともに薄くなる。
◎ :泡ができてかなりの時間保持し泡の表面もほとんど変化がない。
The evaluation criteria are as follows. ○ and ◎ are acceptable ranges for this extinguishing agent.
X: Bubbles are formed but disintegrate immediately.
Δ: Bubbles are formed but gradually collapse.
○: Bubbles are formed and held for a considerable time, but the surface of the bubbles becomes thinner with time.
A: A bubble is formed and held for a considerable time, and the surface of the bubble is hardly changed.
表3により、A成分とB成分とを混合することで、泡のクリーミーさは実施例1、2で比較例1、2と比較して良好である。すなわち実施例及び比較例ともにいずれも泡が発生するにも拘わらず、実施例、特に実施例2ではその泡が強固であり、持続する。また特に、この2液混合型は消火剤は、熱分解は不要となり、小さな火であっても火元を覆って消火することができた。 According to Table 3, the creaminess of the foam is better in Examples 1 and 2 than in Comparative Examples 1 and 2 by mixing the A component and the B component. That is, in both the example and the comparative example, although the bubbles are generated, in the example, particularly in the example 2, the bubbles are strong and last. In particular, in this two-component mixed type, the fire extinguisher is not required to be thermally decomposed, and even a small fire can cover the fire source and extinguish it.
本発明の消火剤は、2成分型なので、混合時点で泡が発生するもので、泡の発生に炎焼しつつある油による熱分解は不要となる。しかも過酸化水素をカタラーゼという分解酵素で泡をつくり、その泡をクリーミーな強いものにして火元を覆って消火することができるので、人体に無害である消火剤として有効に利用することができる。
Since the fire extinguisher of the present invention is a two-component type, bubbles are generated at the time of mixing, and thermal decomposition with oil that is flame-burned to generate bubbles is unnecessary. Moreover, hydrogen peroxide can be made into a foam with a degrading enzyme called catalase, and the foam can be made strong and creamy to cover the fire source and extinguish the fire. .
