Abstract
본 발명은 리튬이온 배터리 화재를 포함한 금속화재의 냉각효과를 증진시킬 수 있는 소화분말의 조성물에 관한 것으로, 보다 구체적으로는 인산암모늄을 함유한 구형 폼글라스(Foamglass)가 섭씨 1,000도 이상 고온의 금속화재 화원(火源)을 덮으면 화원(火源)으로 유입되는 산소의 흐름을 방해하며, 고온에 폼글라스가 녹으면서 폼글라스에 함유되어 있던 인산암모늄이 화원(火源)을 냉각시키면서 소화함과 동시에 섭씨 700~900도에서 녹은 액체 폼글라스가 화원(火源)을 코팅하여 산소의 공급을 차단(질식작용)함으로서 신속한 화재 진압이 가능하도록 하며, 화재진압에 사용된 인산암모늄을 함유한 구형 폼글라스는 회수하여 재사용 또는 재활용이 가능한 금속화재의 냉각효과를 증진시킬 수 있는 소화분말의 조성물에 관한 것이다.The present invention relates to a composition of fire extinguishing powder that can improve the cooling effect of metal fires, including lithium-ion battery fires. More specifically, spherical foam glass containing ammonium phosphate is used to extinguish metal fires at a temperature of more than 1,000 degrees Celsius. Covering the fire source blocks the flow of oxygen flowing into the fire source, and as the foam glass melts at high temperatures, the ammonium phosphate contained in the foam glass cools the fire source and extinguishes it. At the same time, liquid foam glass melted at 700 to 900 degrees Celsius coats the fire source and blocks the supply of oxygen (asphyxiation), enabling rapid fire suppression. Spherical foam containing ammonium phosphate used in fire suppression.

본 발명은 리튬이온 배터리 화재를 포함한 금속화재의 냉각효과를 증진시킬 수 있는 소화분말의 조성물에 관한 것으로, 보다 구체적으로는 인산암모늄을 함유한 구형 폼글라스(Foamglass)가 섭씨 1,000도 이상 고온의 금속화재 화원(火源)을 덮으면 화원(火源)으로 유입되는 산소의 흐름을 방해하며, 고온에 폼글라스가 녹으면서 폼글라스에 함유되어 있던 인산암모늄이 화원(火源)을 냉각시키면서 소화함과 동시에 섭씨 700~900도에서 녹은 액체 폼글라스가 화원(火源)을 코팅하여 산소의 공급을 차단(질식작용)함으로서 신속한 화재 진압이 가능하도록 하며, 화재진압에 사용된 인산암모늄을 함유한 구형 폼글라스는 회수하여 재사용 또는 재활용이 가능한 금속화재의 냉각효과를 증진시킬 수 있는 소화분말의 조성물에 관한 것이다.The present invention relates to a composition of fire extinguishing powder that can improve the cooling effect of metal fires, including lithium-ion battery fires. More specifically, spherical foam glass containing ammonium phosphate is used to extinguish metal fires at a temperature of more than 1,000 degrees Celsius. Covering the fire source blocks the flow of oxygen flowing into the fire source, and as the foam glass melts at high temperatures, the ammonium phosphate contained in the foam glass cools the fire source and extinguishes it. At the same time, liquid foam glass melted at 700 to 900 degrees Celsius coats the fire source and blocks the supply of oxygen (asphyxiation), enabling rapid fire suppression. Spherical foam containing ammonium phosphate used in fire suppression. Glass relates to a composition of fire extinguishing powder that can improve the cooling effect of metal fires that can be recovered and reused or recycled.
화재 발생시 최대 2,000도가 넘는 금속화재는 일반화재 A급, 유류화재 B급 및 전기화재 C급(ABC급)과는 별도로 D급 화재로 분류하고 있으며 나트륨, 칼륨, 기타 금속류의 자연발화와 마그네슘, 알루미늄 등 금속 분말의 분진 폭발의 경우가 있으며 물을 뿌려 금속화재를 진압하면 물은 고온에서 수소와 산소로 분해되어 폭발성이 높은 수소 가스가 발생되어, 오히려 화재의 확산을 돕게 되므로 위험하다.Metal fires with temperatures exceeding 2,000 degrees Celsius are classified as Class D fires separately from Class A general fires, Class B oil fires, and Class C (ABC class) electrical fires. Spontaneous ignition of sodium, potassium, and other metals and magnesium and aluminum fires are classified as Class D fires. There are cases of dust explosions from metal powder, etc., and when a metal fire is extinguished by spraying water, the water decomposes into hydrogen and oxygen at high temperature, generating highly explosive hydrogen gas, which is dangerous because it helps the spread of the fire.
또한 리튬이온 배터리에 화재가 발생하는 경우 섭씨 1,200도 이상의 화염이 폭압을 동반하는 열폭주(Thermal runaway)가 발생하며, 이 열폭주로 인하여 주위의 근접셀이 연쇄적으로 열폭주를 일으키는 열폭주 전이(Propagation)되는 특성으로 인하여 팩을 구성하는 모든 셀이 완전히 연소될때까지 화재를 진압하기 어렵다.In addition, if a fire occurs in a lithium-ion battery, thermal runaway occurs, accompanied by explosion of flames over 1,200 degrees Celsius. This thermal runaway causes a thermal runaway transition in which nearby cells sequentially undergo thermal runaway. Due to the nature of propagation, it is difficult to extinguish the fire until all cells making up the pack are completely burned.
이러한 금속화재는 모래 또는 팽창질석, 팽창진주암, 팽창글라스 등이 일반적인 소화분말로 사용된다. 그러나 이러한 분말들은 산소를 차단하여 소화시킬 뿐 냉각효과가 없기 때문에 화원(火源) 내부에서 방출된 열에너지를 효과적으로 진압할 수 없을 뿐만 아니라 화원(火源)에서 발생되는 가연성 가스가 내부에 축적되는 과정에서 이러한 분말들이 제거될 경우 산소가 다시 연소를 도와 재발화와 순간적으로 격렬한 폭발 반응이 발생하는 문제가 있다.For these metal fires, sand, expanded vermiculite, expanded pearlite, expanded glass, etc. are commonly used as extinguishing powders. However, these powders only extinguish by blocking oxygen and have no cooling effect, so not only are they unable to effectively suppress the heat energy released inside the fire source, but also the process by which combustible gas generated from the fire source accumulates inside. When these powders are removed, oxygen helps combustion again, causing re-ignition and an instantaneous violent explosive reaction.
한편, 등록특허 제10-2094656호에서는 인산암모늄, 실리콘 파우더, 팽창흑연, 전분 배합하는 팽창 절연성 분말 소화약제 조성물을 개시하고 있으며, 화재진압 시에 화원(火源)으로 유입되는 산소를 신속하게 차단함과 동시에 외부 공기와의 단절을 도모함으로써 출중한 소화(消火)기능을 발휘하도록 하였지만 인산암모늄, 실리콘 파우더 및 팽창흑연의 비중 차이로 인하여 인산암모늄이 제일 밑으로 가라앉는 등 조성물 성분들이 각각의 층을 형성하여 방사(放射)시 혼합 방사가 안되어 소화(消火) 기능이 떨어지거나 인산암모늄 단독방사로 인한 폭발 가능성 등의 단점이 있다.Meanwhile, Registered Patent No. 10-2094656 discloses an expanded insulating powder fire extinguishing agent composition containing ammonium phosphate, silicon powder, expanded graphite, and starch, and quickly blocks oxygen flowing into the fire source during fire suppression. At the same time, it has an excellent fire extinguishing function by trying to cut off from the outside air, but due to the difference in specific gravity of ammonium phosphate, silicon powder, and expanded graphite, the composition ingredients sink to the bottom, such as ammonium phosphate sinking to the bottom. There are disadvantages such as poor fire extinguishing function due to lack of mixing and radiation during radiation, or possibility of explosion due to single radiation of ammonium phosphate.
또한 팽창흑연 표면에 인산암모늄을 코팅한 소화약제 조성물의 경우 팽창흑연의 char 형성과 부피증가로 인해 인산암모늄의 냉각 효과가 떨어지는 단점이 있다.In addition, in the case of a fire extinguishing agent composition coated with ammonium phosphate on the surface of expanded graphite, there is a disadvantage in that the cooling effect of ammonium phosphate is reduced due to char formation and increase in volume of expanded graphite.

제2 소화분말인 30g의 제일인산암모늄과 바인더인 1g의 소듐실리케이트(50% 수용액)와 3-글리시독시프로필트리메톡시실란(3-Glycidoxypropyl trimethoxysilane) 3g과 발연현상을 줄일 수 있는 난연 보조제인 Cu2O를 3g 첨가하여 용매인 물과 함께 1L 용기에서 24 시간 동안 볼밀링을 사용하여 분쇄 및 혼합을 수행하였다. 교반기가 부착되어 있는 2L 반응기에 제 1소화분말인 0.3mm 폼글라스(foamglass, Poraver expandedglass) 70g을 넣고 볼밀링을 통해 얻은 제2 소화분말이 함유된 수용액을 서서히 첨가하면서 교반하였다. 이때 반응기의 온도를 50℃로 올려 증발속도를 증가시켰으며 물이 전부 증발할 때까지 교반하였다. 수용액의 경우 물이 증발하면서 분말들끼리 응집하는 경향이 커서 교반이 필요하나 교반이 심할 경우 폼글라스의 균열이나 폼글라스에 붙은 제1 인산암모늄의 분리가 발생할 수 있어 부드러운 실리콘 고무로 코팅한 교반날개를 사용하여 서서히 교반하였다. 이렇게 얻은 제일인산암모늄이 코팅된 폼글라스 분말들은 수분을 흡수하여 다시 응집할 수 있음으로 실리콘 오일이 녹아있는 톨루엔을 이용한 방수 코팅을 수행하였다.30g of monobasic ammonium phosphate as the second fire extinguishing powder, 1g of sodium silicate (50% aqueous solution) as a binder, 3g of 3-Glycidoxypropyl trimethoxysilane, and a flame retardant auxiliary that can reduce the smoke phenomenon. 3 g of Cu 2 O was added, and pulverization and mixing were performed using a ball mill for 24 hours in a 1 L container with water as a solvent. 70 g of 0.3 mm foamglass (Poraver expanded glass), the first fire extinguishing powder, was placed in a 2L reactor equipped with a stirrer, and the aqueous solution containing the second fire extinguishing powder obtained through ball milling was slowly added and stirred. At this time, the temperature of the reactor was raised to 50°C to increase the evaporation rate, and the mixture was stirred until all the water evaporated. In the case of aqueous solutions, the powders tend to cohere as the water evaporates, so stirring is necessary. However, if the stirring is severe, cracks in the foam glass or separation of the monobasic ammonium phosphate attached to the foam glass may occur, so a stirring blade coated with soft silicone rubber is used. It was stirred slowly using . Since the foam glass powder coated with monobasic ammonium phosphate obtained in this way can absorb moisture and re-agglomerate, waterproof coating was performed using toluene with silicone oil dissolved in it.
제2 소화분말인 30g의 제일인산암모늄과 바인더인 2g의 메틸트리메톡시실란(methyltrimethoxysilane)과 3g의 3-글리시독시프로필트리메톡시실란(3-Glycidoxypropyl trimethoxysilane), 난연 보조제인 Cu2O를 3g 첨가하여 용매인 에탄올과 함께 1L 용기에서 24 시간 동안 볼밀링을 사용하여 분쇄 및 혼합을 수행하였다. 교반기가 부착되어 있는 2L 반응기에 0.3 mm 폼글라스(foamglass, Poraver expandedglass) 70g을 넣고 볼밀링을 통해 얻은 알코올용액을 서서히 첨가하면서 교반하였다. 이때 알코올이 전부 증발할 때까지 교반하였다. 수용액의 경우 보다 그 경향이 낮긴 하나 역시 알코올이 증발하면서 분말들끼리 응집하는 경향이 있어 교반이 필요하다. 이때도 실시예 1과 같이 교반이 심할 경우 폼글라스의 균열이나 폼글라스에 붙은 제일인산암모늄의 분리가 발생할 수 있어 부드러운 실리콘 고무로 코팅한 교반날개를 사용하여 서서히 교반하였다. 이렇게 얻은 제일인산암모늄이 코팅된 폼글라스 분말들은 수분을 흡수하여 다시 응집할 수 있음으로 실리콘 오일이 녹아있는 톨루엔을 이용한 방수 코팅을 수행하였다.30g of monobasic ammonium phosphate as the second fire extinguishing powder, 2g of methyltrimethoxysilane as a binder, 3g of 3-Glycidoxypropyl trimethoxysilane, and Cu 2 O as a flame retardant auxiliary. 3g was added and pulverized and mixed using a ball mill for 24 hours in a 1L container with ethanol as a solvent. 70 g of 0.3 mm foam glass (Poraver expanded glass) was placed in a 2L reactor equipped with a stirrer, and the alcohol solution obtained through ball milling was slowly added and stirred. At this time, it was stirred until all the alcohol evaporated. Although this tendency is lower than in the case of an aqueous solution, the powders tend to cohere as the alcohol evaporates, so stirring is necessary. At this time, as in Example 1, if the stirring was severe, cracks in the foam glass or separation of monobasic ammonium phosphate attached to the foam glass could occur, so the mixture was stirred slowly using a stirring blade coated with soft silicone rubber. Since the foam glass powder coated with monobasic ammonium phosphate obtained in this way can absorb moisture and re-agglomerate, waterproof coating was performed using toluene with silicone oil dissolved in it.
실시예 1, 2에 얻어진 제2 소화분말인 인산암모늄분말이 코팅된 폼글라스들을 소화기에 사용하기 위해서는 균질성과 흐름성이 좋아야 함으로 코팅 공정이 끝난 후 체(sieve)를 사용하여 한번 더 거르는 공정을 거칠 수 있다. 아래 표 1에서는 일반 소화분말(팽창글라스)과 실시예 2를 통해 얻은 분말을 사용하여 금속화재에 대한 소화실험 과정을 보여주고 있다.In order to use the foam glass coated with the ammonium phosphate powder, which is the second fire extinguishing powder obtained in Examples 1 and 2, in a fire extinguisher, it must have good homogeneity and flowability, so after the coating process is completed, the process of filtering it again using a sieve is performed. It can be rough. Table 1 below shows the fire extinguishing test process for metal fires using general fire extinguishing powder (expanded glass) and the powder obtained through Example 2.
상기 표 1에서 확인할 수 있는 바와 같이 금속화재 진압에 일반적으로 사용해오던 팽창글라스와 본 발명에 따른 냉각 효과를 증진시킬 수 있는 금속화재 소화분말에 대한 마그네슘 화재진압에 따른 소화시험 결과 마그네슘 화재에 일반적으로 사용해오던 팽창글라스를 사용하면 화재가 진압되었지만 팽창글라스 안에 있는 마그네슘 화원이 냉각되지 못하여 빨갛게 달구어져 있어 언제든지 재발화 위험을 갖고 있지만, 본 발명에 따른 냉각 효과를 증진시킬 수 있는 금속화재 소화분말로 마그네슘 화재를 진압하면 화재가 진압됨과 동시에 화원이 냉각되어 재발화 될 가능성이 없음이 확인되었다.As can be seen in Table 1 above, as a result of fire extinguishing tests using magnesium fire extinguishing for expanded glass, which has been generally used to extinguish metal fires, and the metal fire extinguishing powder that can enhance the cooling effect according to the present invention, magnesium fires are generally The fire was extinguished when the expanded glass was used, but the magnesium fire source inside the expanded glass could not be cooled and was red-hot, so there was a risk of re-ignition at any time. However, magnesium is a metal fire extinguishing powder that can improve the cooling effect according to the present invention. It was confirmed that once the fire was extinguished, the fire source was cooled and there was no possibility of it re-igniting.
이러한 본 발명에 따르면 냉각 효과를 증진시킬 수 있는 금속화재 소화분말을 금속화재에 방사하였을때 폼글라스를 둘러싸고 있는 인산암모늄이 1차로 화재를 소화하면서 인산암모늄을 함유한 폼글라스가 금속화재 화원(火源)을 덮으면 폼글라스가 섭씨 700도 이상에서 녹으면서 방출된 인산암모늄이 최대 섭씨 2,000도 이상 올라간 화원(火源)을 냉각시키고 동시에 액체화 된 폼글라스가 화원(火源)을 코팅하여 화원(火源)으로의 산소 공급을 완전히 차단하여 재발화를 방지하는 등 질식효과 및 냉각효과를 극대화하여 신속하고 안전하게 그리고 완전한 소화를 달성할 수 있는 효과를 제공한다.According to the present invention, when the metal fire extinguishing powder that can enhance the cooling effect is radiated to the metal fire, the ammonium phosphate surrounding the foam glass first extinguishes the fire, and the foam glass containing ammonium phosphate extinguishes the metal fire source (flame). When the foam glass is covered, the ammonium phosphate released as it melts at over 700 degrees Celsius cools the fire source, which has risen to over 2,000 degrees Celsius. At the same time, the liquefied foam glass coats the fire source, killing the fire source. It completely blocks the supply of oxygen to the fire pit to prevent re-ignition and maximizes the suffocation and cooling effects to achieve quick, safe and complete extinguishment.
