Description
본 발명은, 알콜류, 케톤류등의 친수성(親水性)을 가진 가연성액체(可燃性液體)의 소화에 사용되는 신규한 거품소화약제에 관한 것이다.The present invention relates to a novel foam fire extinguishing agent used for the digestion of hydrophilic flammable liquids such as alcohols and ketones.
최근, 화학공업의 발전에 따라, 알콜류, 케톤류등의 친수성을 가진 가연성액체의 제조량, 사용량도 막대한 것으로 나타났다.In recent years, with the development of the chemical industry, the production amount and the amount of use of hydrophilic flammable liquids such as alcohols and ketones have also been enormous.
그리고, 물에 용해가능한 가연성 액체의 화재에는, 가솔린, 경유, 중유와 같은 물에 용해되지 않는 가연성액체의 화재의 소화에 유효한 단백질 거품소화약제 혹은 계면활성제계거품소화약제(界面活性劑系거품消火藥劑)를 그대로 사용할 수는 없다. 그 이유는, 상기 포말소화약제의 포말과 친수성을 가진 가연성액체와가 접촉한 순간에 포말의 수분이 가연성액체에 흡수되어서, 거품의 형태를 보지하지 못하고, 소멸되어 버리므로, 소화가 불가능하게 되기 때문이다. 이 때문에 종래에는 단백질의 가분해 농축액을 주체로 하고, 이것에 다량의 금속비누를 배합하여, 포말을 물에 용해되지 않는 금속비누막으로 피복함으로써 거품의 소멸을 방지하는 방법을 채용하였었다.Also, a fire of a flammable liquid which is soluble in water is a protein foaming agent or a surfactant-based foaming agent effective for extinguishing a fire of a flammable liquid which is not soluble in water such as gasoline, diesel, or heavy oil.藥劑) cannot be used as it is. The reason for this is that at the moment of contact with the foam of the foam fire extinguishing agent and the hydrophilic flammable liquid, the moisture of the foam is absorbed by the flammable liquid, and the foam form is not observed and is extinguished. Because. For this reason, conventionally, a method of preventing the disappearance of bubbles by employing a protein hydrolyzate concentrated mainly by mixing a large amount of metal soap and coating the foam with a metal soap film insoluble in water.
그런데, 이와같은 거품소화약의 제조에는 동물성단백질의 가수분해를 비롯하여, 상당히 복잡한 처리공정을 필요로하며, 악취를 발생시키는 등의 공해적요소도 많고, 또 품질적으로도 불안정하며, 또 단백질가수분해물을 주성분으로 하는 거품에는 유동성(流動性)이 적은 것도 결점의 하나로 되어 있었다.However, the preparation of such foam fire extinguishing agent requires a fairly complicated treatment process, including hydrolysis of animal protein, has many pollution factors such as generating odor, and is unstable in quality, and also is a protein singer. One of the drawbacks is the low flowability of the foam having the decomposition product as a main component.
본 발명은, 상기의 상태에 비추어, 이들 문제를 해결하기 위하여 창안된 것이다. 다음에, 본 발명의 골자에 대해서 설명한다면, 본 발명에 있어서는 덱스트린(C6H10O5)n이, 물에는 다량으로 그리고 완전하게 용해하는 반면 농(濃)알콜에는 용해하지 않고 고화석출(固化析出)한다는 사실에 착안하고, 종래의 단백질 가수분해농축액 대신에 다량의 덱스트린을 주성분으로 하고, 이것에 아니온계 또는 양성(兩性)의발포성 계면활성제를 첨가함으로써 소화약제에 기포성을 부여하고, 또 유기금속염과 지방산을 배합 첨가하여 유효한 친수성가연액체용 포말소화약제를 얻는것에 성공을 하였다.The present invention has been devised to solve these problems in view of the above state. Next, when the bones of the present invention are described, dextrin (C 6 H 10 O 5 ) n is dissolved in large quantities and completely in water, while it does not dissolve in concentrated alcohol but solidified precipitate ( Paying attention to the fact that it is 固化 析出, a large amount of dextrin as a main component instead of the conventional protein hydrolyzate concentrate, and adding an anionic or amphoteric foaming surfactant to this to impart foaming to the extinguishing agent, It was successful to obtain an effective foam fire extinguishing agent for hydrophilic flammable liquids by combining organometallic salts and fatty acids.
본 발명의 포말소화약제의 바람직한 조성(組成)은 다음과 같다.Preferred compositions of the foam fire extinguishing agent of the present invention are as follows.
그리고, 덱스트린은 전분을 가수분해하여 얻는 것으로, 종래에는 주로 호료(糊料)로서 섬유공업등에 대량으로 사용되어 왔으며, 여러가지의 분해생성물이 알려져 있지만, 본 발명에 사용하는 덱스트린은 냉수에 녹을 수 있는 것이면 되고, 색조(色調)등은 고려할 필요가 없다. 또 발포성계면활성제는 아니온계 또는 양성(兩性)의 발포성계면활성제의 1종 또는 2종 이상을 첨가하는 것이지만 본 발명에서는 아니온계의 것으로서 고급알콜 황산에스테르염, 고급알콜에테르의 황산에스테르염, 폴리옥시에틸렌 설페이트염, 양성의 것으로서 알킬베타인형 활성제등을 좋은 예로서 들 수 있다. 또 유기금속염으로서는 유산알미늄을 들 수 있고, 지방산류로서는 라우르산, 스테아르산, 올레산, 리놀산을 들 수 있다. 또, 용제로서는 저급알콜류, 글리콜에테르류, 글리콜류, 아민류의 1종 또는 2종 이상을 사용한다.Dextrin is obtained by hydrolyzing starch. In the past, dextrin has been used in large quantities in textile industry as a main ingredient, and various decomposition products are known, but dextrin used in the present invention can be dissolved in cold water. It does not need to consider color tone etc. In addition, the foamable surfactant is one or two or more of an anionic or amphoteric foaming surfactant, but in the present invention, it is an anionic-based higher alcohol sulfate ester salt, higher alcohol ether sulfate salt, polyoxy Ethylene sulfate salt, an alkyl betaine type | mold activator, etc. are mentioned as a good example as a positive thing. Examples of the organometallic salts include aluminum lactic acid, and examples of the fatty acids include lauric acid, stearic acid, oleic acid and linoleic acid. Moreover, 1 type (s) or 2 or more types of lower alcohols, glycol ethers, glycols, and amines are used as a solvent.
이상의 성분으로 된 본 발명의 친수성가연액체용 포말소화약제는, 종래의 단백질계포말소화약제에 비교하여 제조가 매우 간단할뿐만 아니라 단백질계포말소화약제 특유의 악취가 나지 않고, 또 6%로 희석된 수용액에 의한 거품은 유동성이 풍부하며, 친수성가연액체의 액면에 확산하여 소화효과는 양호하다. 또 아니온계의 발포성계면활성제는 거품을 내는 성질이 강하고, 양성(兩性)의 발포성계면활성제는 거품을 강하게 하고, 동시에 소화장치 혹은 파이프 등의 부식을 방지하는 성질을 지니고 있다.The foam fire extinguishing agent for hydrophilic flammable liquids of the present invention having the above components is very simple to prepare as compared to the conventional protein foam fire extinguishing agent, and does not produce the odor peculiar to protein foam fire extinguishing agent and is diluted to 6%. The foam by the aqueous solution is rich in fluidity, and the extinguishing effect is good by diffusing to the liquid surface of the hydrophilic flammable liquid. In addition, anionic foaming surfactants have a strong foaming property, and positive foaming surfactants have a strong foaming property and at the same time have a property of preventing corrosion of a fire extinguishing device or pipe.
다음에 본 발명의 포말소화약제의 실시예를 표시한다.Next, the foam extinguishing agent of this invention is shown.
[실시예]EXAMPLE
상기의 성분조성으로 이루어진 거품소화약제의 6%수용액으로 발포배율 약 6배의 거품을 만들고, 메타놀, 에타놀, 부타놀 및 프로파놀에 대하여 거품의 내액성(耐液性)을 조사하였는데, 어느것도 시판하고 있는 단백질계친수성가연액체용 거품소화약제에 비교하여 양호한 결과를 얻을 수가 있었다. 그 결과, 소화제에 포함되는 덱스트린이, 물에 용해하지만, 농(濃)알콜에는 용해하지 않고 고화석출(固化析出)하기 때문이다.6% aqueous solution of the foam fire extinguishing agent composed of the above-mentioned ingredient composition was used to make a foam having a foaming ratio of about 6 times, and the liquid resistance of the foam was examined with respect to methanol, ethanol, butanol and propanol. Good results were obtained compared to commercially available foam fire extinguishing agents for protein-based hydrophilic flammable liquids. As a result, the dextrin contained in the extinguishing agent dissolves in water, but does not dissolve in concentrated alcohol but precipitates in solidified form.
