Description
본 발명은 수성 에폭시 에멀젼, 세라믹계 무기필러, 120 내지 350℃의 온도에서 자가 온도 감응하는 코어-쉘 구조인 초기화재 소화용 마이크로 캡슐을 포함하여 지하구 화재 발생을 초기에 진압할 수 있는 지하구 초기 화재 진화용 자가 온도 감응 소화 도료 조성물에 관한 것이다.The present invention is an underground tunnel that can initially extinguish an underground fire, including an aqueous epoxy emulsion, a ceramic-based inorganic filler, and an initial fire extinguishing microcapsule with a core-shell structure that is self-temperature sensitive at a temperature of 120 to 350 ° C. It relates to a self-temperature sensitive fire extinguishing paint composition for initial fire extinguishing.
지하구는 지상부 공간의 미관을 개선하고 지상의 공간 효율을 확보하기 위해 지하에 시설들을 설치한 것으로, 공도전기, 가스, 수도시설 등의 공급설비, 통신시설 등 지하매설물을 공동 수용하는 공동구와 전력구, 또는 통신구와 같이 단일 종류의 시설만을 설치한 지하공작물을 매설한 기관의 단독구 및 아파트, 학교, 병원 및 각 기업에서 건물주가 건축허가를 받아 지하에 시설한 일반구 등으로 구분할 수 있다.The underground tunnel is a facility installed underground to improve the aesthetics of the above-ground space and secure above-ground space efficiency. The utility and power tunnels jointly accommodate underground facilities such as supply facilities such as public electricity, gas, and water facilities, and communication facilities. , or it can be divided into a single district of an institution with buried underground structures that install only a single type of facility, such as a communication district, and a general district where the building owner of an apartment, school, hospital, or each company has installed underground facilities with a building permit.
이런 지하구는 대부분 지하 밀폐 구조 특성상 화재가 진행됨에 따라 산소가 부족하게 되어 불완전 연소를 하게 되어 다량의 연기를 발생한다. 또한, 진입구가 협소하고, 내부의 배선 선반 (cable tray)이나 배관 등으로 인해 소화 활동이 어려운 공간적 특성이 있고, 대부분의 전력 통신 케이블은 절연재료 및 외피 재질에 폴리에틸렌이나 폴리염화비닐 등을 사용하여 화재 발생 시 짙은 연기와 유독성가스를 발생시키므로 소화 활동이 어렵다. Due to the closed nature of most underground tunnels, as the fire progresses, oxygen becomes insufficient, leading to incomplete combustion and a large amount of smoke. In addition, there are spatial characteristics that make fire extinguishing difficult due to narrow entrances and internal cable trays and piping, and most power communication cables use polyethylene or polyvinyl chloride for the insulating material and outer shell material. When a fire breaks out, it produces thick smoke and toxic gases, making fire extinguishing difficult.
또한, 지하의 규모가 커서 특정 조건을 만족할 경우 일정 길이마다 방화벽을 설치하지만, 대부분의 소규모 지하구의 경우 지하구 내에 별도의 방화벽을 설치하지 않아서 케이블 등의 가연재에 화재가 발생하면 연속적으로 연소 확대 될 우려가 크고, 화재를 진압하기 위해서는 발화점이나 내부 상황을 알 필요가 있으나 짙은 연기와 유해가스 등으로 확인이 어려워 진압활동을 효과적으로 수행하기 어렵고 이로 인해 화재 진압에도 상당한 시간이 걸린다.In addition, if the underground is large and meets certain conditions, firewalls are installed at certain lengths. However, in most small underground tunnels, separate firewalls are not installed within the underground tunnel, so if a fire occurs in combustible materials such as cables, combustion continues to spread. In order to extinguish a fire, it is necessary to know the ignition point or internal situation, but it is difficult to confirm due to thick smoke and harmful gases, making it difficult to effectively extinguish the fire. As a result, it takes a considerable amount of time to extinguish the fire.
이와 관련하여, 공개특허 10-2021-0106828호에 통신용, 전력용 등 다양한 케이블이 설치된 구간에서 비난연케이블을 화재로부터 차단하여 보호하기 위한 난연도료 및 이러한 난연도료를 케이블에 도포하기 위한 전기통신케이블의 화재방지용 도료 도포 시공 방법이 개시되어 있으나, 케이블을 화재로부터 차단하여 보호하는 것에 중점을 둔 것으로, 피도물로 케이블에 사용하는 것 이외 다른 피도물을 사용할 수 없는 단점이 있고, 화재 발생시 초기 화재를 진압하고, 화재의 확산 및 재연소를 방지하는 효과는 부족한 단점을 가지고 있다.In this regard, in Publication Patent Publication No. 10-2021-0106828, flame paint for blocking and protecting non-flammable cables from fire in sections where various cables for communication, power, etc. are installed, and telecommunication cables for applying such flame paint to cables A method of applying fire prevention paint has been disclosed, but it focuses on blocking and protecting cables from fire, and has the disadvantage of not being able to use other coating materials other than those used on cables, and extinguishing the initial fire when a fire occurs. However, it has the disadvantage of being insufficient in preventing the spread of fire and re-combustion.
따라서, 지하구내 콘크리 벽면과 철재, 알루미늄, 냉열강판, 아연도금강판, 구도막의 구조물과 시설, 전력/통신케이블 어느 재질에 제한하지 않고 도장이 가능하며, 초기에 화재 발생을 진압하고, 화재 확산 및 재연소 방지를 통해 화재의 피해를 극소화 시킬 수 있는 도료 조성물이 요구된다.Therefore, it is possible to paint concrete walls in underground structures, steel, aluminum, cold-heated steel sheets, galvanized steel sheets, structures and facilities of old coatings, and power/communication cables without being limited to any material. It is possible to suppress fires at an early stage, reduce the spread of fire, and prevent fires from spreading. A paint composition that can minimize fire damage by preventing re-combustion is required.

However, the following examples are only for illustrating the content of the present invention and are not intended to limit the present invention.
본 발명의 지하구 초기 화재 진화용 자가 온도 감응 소화 도료 조성물은 수성 에폭시 에멀젼; 세라믹계 무기필러; 및 120 내지 350℃의 온도에서 자가 온도 감응하는 코어-쉘 구조인 초기화재 소화용 마이크로 캡슐을 포함한다. The self-temperature-sensitive fire extinguishing paint composition for extinguishing an initial underground fire of the present invention includes an aqueous epoxy emulsion; Ceramic inorganic filler; and a microcapsule for extinguishing an initial fire, which has a core-shell structure that is self-temperature sensitive at a temperature of 120 to 350°C.
우선, 도료는 바인더(binder), 용제, 안료 및 첨가제 등으로 구성되며, 이 중 바인더는 도장 후 도막을 형성하고 광택이나 은폐력 등 외관을 결정하며 안료가 균일하게 퍼지게 하고 밀착이 원활하도록 해주는 등의 역할을 한다.First of all, paint is composed of a binder, solvent, pigment, and additives. Among these, the binder forms a film after painting, determines the appearance such as gloss and hiding power, spreads the pigment evenly, and ensures smooth adhesion. It plays a role.
본 발명의 지하구 초기 화재 진화용 자가 온도 감응 소화 도료 조성물은 바인더로서 수성 에폭시 에멀젼을 포함할 수 있으며, 상기 수성 에폭시 에멀젼은 아크릭 에멀젼, 페놀 노보락 에멀젼, 수분산 우레탄 수지(PUD), 에폭시 변성 에멀젼 등의 바인더 중 선택되는 하나 이상일 수 있으며, 바람직하게 에폭시 변성 에멀젼일 수 있으나, 이에 제한되는 것은 아니다.The self-temperature sensitive fire extinguishing paint composition for extinguishing an initial fire in an underground tunnel of the present invention may include a water-based epoxy emulsion as a binder, and the water-based epoxy emulsion includes acrylic emulsion, phenol novolac emulsion, water-dispersed urethane resin (PUD), and epoxy modified. It may be one or more binders such as emulsions, and is preferably an epoxy-modified emulsion, but is not limited thereto.
상기 에폭시 변성 에멀젼은, 예를 들어 비스페놀A 에폭시 수지와 알리파틱 불포화 지방산을 반응시켜 에폭시 에스테르 형태의 변성 에폭시 수지를 제조하여 계면활성제로 디이소시아네이트를 가교반응시킨 후 물과 친수성 용매를 적하시켜 제조된 1액형 수성 에폭시 에멀젼일 수 있다.The epoxy-modified emulsion is prepared by, for example, reacting a bisphenol A epoxy resin with an aliphatic unsaturated fatty acid to prepare an epoxy ester-type modified epoxy resin, crosslinking diisocyanate with a surfactant, and then adding water and a hydrophilic solvent dropwise. It may be a one-component water-based epoxy emulsion.
상기 1액형 수성 에폭시 에멀젼은 2액형의 아민 에폭시 수지 등과는 다르게 경화제를 요하지 않으며, 상온에서 자연경화 건조시간이 빠르고, 부착성, 내수성, 내식성(방청성), 내화학성, 작업성과 같은 물성이 우수한 친환경적인 바인더이며, 유리전이온도(TG) 1~5℃, 불휘발분(NV) 50±1%, 점도 700~1200cps, PH 6~8 및 비이온성의 특징을 갖는다. Unlike the two-component amine epoxy resin, the one-component water-based epoxy emulsion does not require a hardener, cures naturally at room temperature, has a fast drying time, and is eco-friendly with excellent physical properties such as adhesion, water resistance, corrosion resistance (rust prevention), chemical resistance, and workability.

상기 수성 에폭시 에멀젼의 함량이 30 중량% 이하 일 경우 점도가 높아져서 도장작업 시 붓이나 롤러로 도막을 올리는 데 힘이 들고, 40 중량% 이상일 경우 점도가 낮아져 도장작업 시 젖은 도막이 흐를 수 있다.If the content of the water-based epoxy emulsion is 30% by weight or less, the viscosity increases, making it difficult to raise the paint film with a brush or roller during painting, and if the content is 40% by weight or more, the viscosity is low and the wet film may flow during painting.
상기 수성 에폭시 에멀젼은 휘발성 유기화합물(VOCs) 배출량이 0.0076g/L보다 낮아 친환경적인 바인더이다.The water-based epoxy emulsion is an environmentally friendly binder with volatile organic compounds (VOCs) emissions lower than 0.0076 g/L.

본 발명의 일구현예에 있어서, 상기 소화 도료 조성물은 단열, 결로방지, 내화성능 향상을 위해 세라믹계 무기필러로서 입자사이즈 60~80㎛, 연화점 1,800℃의 화산폭발 시 발생한 특수 화성암을 고온 발포시킨 중공체(MSD600)를 5 내지 10 중량% 포함할 수 있고, 바람직하게 7 중량% 포함할 수 있다.In one embodiment of the present invention, the fire extinguishing paint composition is made by foaming special igneous rock generated during a volcanic eruption with a particle size of 60-80㎛ and a softening point of 1,800°C at high temperature as a ceramic-based inorganic filler to improve heat insulation, condensation prevention, and fire resistance.

도 1은 본 발명의 소화 도료 조성물이 경화 건조되면서 형성된 지하구 초기 화재 진화용 자가 온도 감응 소화 도료 도막 단면도를 나타내는 도면이다.Figure 1 is a cross-sectional view of a self-temperature sensitive fire extinguishing paint film for extinguishing an initial fire in an underground tunnel formed while the fire extinguishing paint composition of the present invention is cured and dried.
도 1a는 초기화재 소화용 마이크 캡슐(10), 세라믹계 무기필러(용융알루미나+규산지르코늄+화성암을 고온 발포시킨 중공체+용융실리카+인산아연)를 포함하는 조성물을 피도물(30)에 도포하여 경화 건조되기 전의 상태를 나타낸 것이다.Figure 1a shows a composition containing a microphone capsule 10 for extinguishing an initial fire and a ceramic inorganic filler (fused alumina + zirconium silicate + a hollow body obtained by high-temperature foaming of igneous rock + fused silica + zinc phosphate) applied to the object 30. This shows the state before curing and drying.
도 1b는 상기의 입자들이 각각 순차적으로 형성한 초기화재 소화용 마이크 캡슐(10a), 세라믹계 무기필러층(20a)을 나타낸 것이다.Figure 1b shows the microphone capsule 10a for extinguishing an initial fire and the ceramic-based inorganic filler layer 20a formed sequentially by the above particles, respectively.
본 발명의 도료 조성물은 경화하면서 초기소화용 마이크로 캡슐층(10a)이 도막의 최상부에, 그 아래에 세라믹계 무기필러층(20a)이 배열될 수 있으며, 경화 건조되면서 초기소화용 마이크로 캡슐층(10a)이 도막의 최상부에 위치할 수 있는데, 상기와 같이 최상부에 위치함으로써 화재 발생시 마이크로 캡슐이 신속하게 온도를 자가감응하여 기화된 조성물이 화염에 직접 분사되어 빠르게 초기 화재에 대응할 수 있는 효과가 있다.When the coating composition of the present invention is cured, the microcapsule layer for initial extinguishing (10a) may be arranged at the top of the coating film, and the ceramic-based inorganic filler layer (20a) may be arranged below it, and as it is cured and dried, the microcapsule layer for initial extinguishing ( 10a) can be located at the top of the coating film, and by being located at the top as above, the microcapsules quickly self-sensitize the temperature when a fire occurs, and the vaporized composition is sprayed directly into the flame, which has the effect of quickly responding to the initial fire. .
본 발명의 도료 조성물에는 120 내지 350℃의 온도에서 자가 온도 감응하는 코어-쉘 구조인 초기화재 소화용 마이크로 캡슐이 포함될 수 있다. The coating composition of the present invention may include microcapsules for extinguishing initial fire, which have a core-shell structure that is self-temperature sensitive at a temperature of 120 to 350°C.
상기 초기화재 소화용 마이크로 캡슐은 도 2에 나타낸 바와 같이, 코어-쉘 구조를 포함한 구조를 포함한 형태로 구성될 수 있다.As shown in FIG. 2, the microcapsule for extinguishing an initial fire may be configured in a form including a core-shell structure.
코어-쉘 구조로 이루어진 본 발명의 마이크로 캡슐의 경우, 마이크로 캡슐 내의 소화물질이 외부로 배출되어 화재를 초기에 소화하는 용도로 사용된다.In the case of the microcapsule of the present invention consisting of a core-shell structure, the extinguishing agent in the microcapsule is discharged to the outside and is used to extinguish the fire at an early stage.
구체적으로, 화재 발생 시 소화 조성물이 열에 의해 기화되어 팽창될 수 있으나, 상기 쉘부의 내구성 및 기밀성에 의해 파열, 누출하지 않고 있다가 화재 시 120C~350℃의 화염온도를 자가감응하여 터지게 되며, 이로 인해 기화된 소화 조성물이 화염에 직접 분사작용하여, 연소의 4조건인 연료(가연물), 산소(공기), 열(발화원), 연쇄반응 중 열(발화원)과 연쇄반응을 끊어 주어 화재를 소화할 수 있으며, 15초 이내에 800℃에서 30℃로 냉각시켜 재연소를 억제할 수 있다.Specifically, in the event of a fire, the fire extinguishing composition may evaporate and expand due to heat, but due to the durability and airtightness of the shell, it does not rupture or leak, but bursts in response to a flame temperature of 120°C to 350°C in the event of a fire. As a result, the vaporized fire extinguishing composition is sprayed directly on the flame, extinguishing the fire by breaking the four conditions of combustion: fuel (combustibles), oxygen (air), heat (ignition source), and heat (ignition source) and chain reaction. and re-burning can be suppressed by cooling from 800℃ to 30℃ within 15 seconds.
본 발명의 초기화재 소화용 마이크로 캡슐은 내부에 폐공간이 형성된 마이크로 크기의 쉘부와, 쉘부의 내측에 위치하는 코어부 상의 소화 조성물을 포함한다.The microcapsule for extinguishing an initial fire of the present invention includes a micro-sized shell portion with a closed space formed therein, and a fire extinguishing composition on the core portion located inside the shell portion.
상기 쉘부는 마이크로 캡슐의 외형을 형성하며, 화재 발생 시 열폭주로 120~350℃에 도달하면 이 온도를 자가 온도 감응해서 8초 이내에 녹아 터져 코어 내의 소화물질이 분사되어, 초기에 소화할 수 있는 열가소성 수지로 형성할 수 있다.The shell part forms the appearance of a microcapsule, and when a fire occurs and reaches 120~350℃ due to thermal runaway, it automatically responds to this temperature and melts and bursts within 8 seconds, spraying the fire extinguishing agent in the core, allowing for initial fire extinguishment. It can be formed from thermoplastic resin.
바람직하게 상기 쉘부는 온도 반응에 의한 역할을 수행하기 위하여, 비다공성 고분자 중합체로 이루어질 수 있다. 상기 비다공성 고분자 중합체의 예로, 폴리우레탄 수지, 폴리우레아 수지, 폴리아미드 수지, 폴리에스테르 수지, 폴리카보네이트 수지, 아미노알데히드 수지, 멜라민 수지, 폴리스티렌 수지, 스티렌-아크릴레이트 공중합체 수지, 스티렌-메타 크릴레이트 공중합체 수지, 젤라틴, 폴리비닐알코올, 페놀포름알데이드 수지 및 레소시놀 포름알데히드 수지에서 선택된 1종 이상을 사용할 수 있다. Preferably, the shell portion may be made of a non-porous high molecular weight polymer in order to function in response to temperature. Examples of the non-porous polymers include polyurethane resin, polyurea resin, polyamide resin, polyester resin, polycarbonate resin, aminoaldehyde resin, melamine resin, polystyrene resin, styrene-acrylate copolymer resin, and styrene-methacryl. One or more types selected from late copolymer resin, gelatin, polyvinyl alcohol, phenol formaldehyde resin, and resorcinol formaldehyde resin can be used.
보다 바람직하게는 멜라민-요소-포름알데히드 수지(Melamine-Urea-formaldehyde resin)를 사용할 수 있으며, 상기 멜라민-요소-포름알데히드 수지는 온도 감응이 민감한 특성을 가지는 바, 120~350℃ 범위 온도에서 민감하게 자가감응하여 쉘부가 파괴되어 소화 물질이 분사되게 하므로서 우수한 화재 초기의 소화 효과를 얻을 수 있다.More preferably, melamine-urea-formaldehyde resin can be used. The melamine-urea-formaldehyde resin has sensitive temperature sensitivity, and is sensitive to temperatures in the range of 120 to 350°C. Excellent fire extinguishing effect in the early stage of fire can be achieved by self-sensing, destroying the shell and spraying extinguishing substances.
본 발명의 일실시예에 있어서, 상기 쉘부의 내측에 존재하는 코어부에는 소화 조성물이 포함될 수 있다.In one embodiment of the present invention, a fire extinguishing composition may be included in the core portion present inside the shell portion.
상기 소화 조성물은 퍼플루오로 2-메틸-3-펜타논(Perfluoro 2-methyl-3-pentanone) 및 1,1,2,2,3,3,4-헵타플루오로 사이클로펜테인(1,1,2,2,3,3,4-heptafluoro cyclopentane)을 포함할 수 있으며, 상기 두 가지의 소화물질은 쉘 내부에서 저장 안정성이 뛰어나며, 쉘 외부로 방출 시 효과적인 분사효율을 나타낼 수 있다.The fire extinguishing composition includes perfluoro 2-methyl-3-pentanone and 1,1,2,2,3,3,4-heptafluoro cyclopentane (1,1 , 2,2,3,3,4-heptafluoro cyclopentane), and the above two extinguishing substances have excellent storage stability inside the shell and can exhibit effective spray efficiency when released outside the shell.
본 발명의 일실시예에 있어서, 상기 퍼플루오로 2-메틸-3-펜타논 및 1,1,2,2,3,3,4-헵타플루오로 사이클로펜테인은 1:3~3:1의 비율로 혼합하여 사용할 수 있으며, 바람직하게 1:1의 비율로 혼합하여 사용할 수 있다.In one embodiment of the present invention, the perfluoro 2-methyl-3-pentanone and 1,1,2,2,3,3,4-heptafluoro cyclopentane are 1:3 to 3:1. It can be used by mixing at a ratio of , preferably at a ratio of 1:1.
상기 퍼플루오로 2-메틸-3-펜타논 및 1,1,2,2,3,3,4-헵타플루오로 사이클로펜테인의 비율이 1:3 미만일 경우 소화능력 및 쉘의 코어 내 소화물질의 저장 안정성에 문제가 발생할 수 있다.When the ratio of perfluoro 2-methyl-3-pentanone and 1,1,2,2,3,3,4-heptafluoro cyclopentane is less than 1:3, fire extinguishing ability and extinguishing substances in the core of the shell Problems may arise with storage stability.
상기 초기화재 소화용 마이크로 캡슐의 0.5~0.9mm로 조절되는 것이 바람직하며, 상기 입경이 0.5mm 미만일 경우, 120 내지 350℃의 불꽃온도를 자가 감응 성능은 동일하나 소화능력이 부족할 수 있고, 0.9mm를 초과하는 경우 피도물 표면의 특정 부위에 도포시키는 공정상 어려움이 있을 수 있다.It is preferable that the initial fire extinguishing microcapsule is adjusted to 0.5 to 0.9 mm. If the particle size is less than 0.5 mm, the self-sensing performance for a flame temperature of 120 to 350 ° C is the same, but the fire extinguishing ability may be insufficient, and the 0.9 mm If it exceeds, there may be difficulties in the process of applying it to a specific area on the surface of the object.
본 발명의 일실시예에 있어서, 상기 초기화재 소화용 마이크로 캡슐은 도료 조성물의 전체 중량을 기준으로 5 내지 15 중량% 포함될 수 있고, 바람직하게 10 내지 15 중량% 포함될 수 있으며, 보다 바람직하게 10 내지 13 중량% 포함될 수 있다.In one embodiment of the present invention, the microcapsules for extinguishing an initial fire may be included in an amount of 5 to 15% by weight, preferably 10 to 15% by weight, more preferably 10 to 15% by weight, based on the total weight of the coating composition. It may contain 13% by weight.
상기 초기화재 소화용 마이크로 캡슐의 함량이 5 중량% 미만일 경우 초기 소화 효과가 부족해지는 문제가 발생할 수 있고, 15 중량% 초과할 경우 도료 점도의 상승으로 도장 작업성이 나빠지고 건조 도막의 내구성이 저하되며 제조원가 측면에서 부적절한 문제가 있다.If the content of the microcapsules for extinguishing the initial fire is less than 5% by weight, the problem of insufficient initial fire extinguishing effect may occur, and if it exceeds 15% by weight, the painting workability deteriorates due to an increase in the viscosity of the paint and the durability of the dry coating film deteriorates. There is an inappropriate problem in terms of manufacturing cost.
도 3은 본 발명의 소화 도료 조성물을 건조 및 경화시킨 경화물을 잘게 분쇄한 알갱이에 불꽃을 점화하고 소화시킬 때 시간별 상태를 나타낸 실제 사진으로, 여기에서 3a는 점화 전(0초), 3b는 4초 후, 3c는 8초 후, 3d는 15초 후의 상태를 나타낸다.Figure 3 is an actual photograph showing the state over time when a flame is ignited and extinguished in finely ground particles of the dried and hardened cured product of the fire extinguishing paint composition of the present invention, where 3a is before ignition (0 seconds) and 3b is 4 seconds later, 3c represents 8 seconds later, and 3d represents 15 seconds later.
점화 후 8초까지는 상기 알갱이가 연소되어 발화되다가 8초 이후 차츰 소화되어 15초 후 완전 소화된 경향을 보이는데, 이는 조성물에 포함되어 있던 마이크로 캡슐의 쉘부가 화재 발생 시 열폭주로 120~350℃에 도달하여 온도를 감지(자가 온도 감응)해서 8초 내에 녹아 터져 코어내의 소화물질이 분사되고, 소화물질이 15초 이내에 800℃에서 30℃로 냉각시켜 재연소를 억제할 수 있으므로 상기와 같은 경향을 보이는 것으로 볼 수 있다.The particles are burned and ignited for up to 8 seconds after ignition, but after 8 seconds, they are gradually extinguished and tend to be completely extinguished after 15 seconds. This is because the shell of the microcapsule contained in the composition undergoes thermal runaway at 120-350°C when a fire occurs. When it reaches the core, it detects the temperature (self-temperature response) and melts and bursts within 8 seconds, spraying the fire extinguishing material in the core. The fire extinguishing material can be cooled from 800℃ to 30℃ within 15 seconds to suppress re-combustion, so the above tendency is observed. It can be seen as visible.
도 4는 초기화재 소화용 마이크로 캡슐의 시차주사 열량분석(DSC, Differential Scanning Calorimetry) 곡선 및 온도 변화에 따른 마이크로 캡슐 변화(SEM Image)를 나타내는 도면으로, 72℃ 부근에서는 마이크로 캡슐이 구형으로 존재하고 있으나, 150℃ 부근에서는 온도 감응을 하여 쉘부가 파열된 형태로 존재하는 것을 확인함으로써, 120~350℃ 감응온도 범위에서는 코어내의 소화물질이 분사될 수 있는 것을 알 수 있었다.Figure 4 is a diagram showing the Differential Scanning Calorimetry (DSC) curve of the microcapsule for extinguishing an initial fire and the microcapsule change (SEM Image) according to temperature change. At around 72°C, the microcapsule exists in a spherical shape. However, it was confirmed that the shell part exists in a ruptured form through temperature sensitivity around 150℃, confirming that the extinguishing agent in the core can be sprayed in the response temperature range of 120~350℃.

<시험예 2> 물성 측정<Test Example 2> Physical property measurement
상기 시험예 1에서 형성한 건조 도막을 하기 표 5와 같이 각각의 시험규격을 통해 항목을 측정하였다.The items of the dried coating film formed in Test Example 1 were measured according to each test standard as shown in Table 5 below.
그 결과 하기 표 6 내지 7에 나타낸 바와 같이, 실시예 1 내지 4의 경우, 형성한 건조 도막의 부착력, 내식성, 내산성, 내알칼리성, 내수성, 열방출율, 가스유해성 및 내습성 등이 모두 우수하였으나, 비교예 1 내지 9의 경우, 실시예 1 내지 4에 비해 물성이 떨어지는 것을 확인하였다. As a result, as shown in Tables 6 to 7 below, in the case of Examples 1 to 4, the adhesion, corrosion resistance, acid resistance, alkali resistance, water resistance, heat release rate, gas toxicity, and moisture resistance of the formed dry coating film were all excellent.

<시험예 3> 건조도막 형성 후 소화성능 측정<Test Example 3> Measurement of fire extinguishing performance after forming a dry film
가로 160mm, 세로 210mm, 높이 210mm의 플라스틱 재질로 되어 있고, 상면이 개방되어 있는 사각통 형태의 내부에 버너를 고정하고 점화하였다.It was made of plastic measuring 160mm wide, 210mm long, and 210mm high, and a burner was fixed and ignited inside a square cylinder with an open top.
상기 실시예의 건조 도막이 형성된 일면을 개방되어 있는 상면을 덮어 버너의 불꽃이 상기 일면과 접촉하도록 하여 밀폐한 후, 버너의 불꽃이 밀폐된 상태에서 초기소화 자가감응온도, 초기소화시간 및 재연소 억제 시간을 측정했다. After sealing one surface on which the dry coating film of the above embodiment is formed by covering the open upper surface so that the flame of the burner comes into contact with the surface, the initial self-extinguishing self-sensing temperature, initial extinguishing time, and re-combustion suppression time are determined with the flame of the burner sealed. was measured.
여기에서 초기소화 자가감응온도는 디지털 온도계를 사용하여 버너의 불꽃이 상기 일면과 접촉하여 마이크로캡슐이 반응할 때의 온도를 측정한 것이다.Here, the initial extinguishing self-sensing temperature is measured using a digital thermometer when the microcapsule reacts when the burner flame contacts the surface.
측정결과는 하기의 표 8과 같았다. 비교예 3 내지 9의 경우 화재를 소화시킬 수 있는 마이크로 캡슐을 포함하고 있지 않아, 소화 성능을 측정할 수 없었다.The measurement results were as shown in Table 8 below. Comparative Examples 3 to 9 did not contain microcapsules capable of extinguishing fire, so fire extinguishing performance could not be measured.

digestion time
- 초기소화시간: 점화 후 마이크로 캡슐이 감응한 시점에서 불꽃(화염)이 사라지고 최초로 연기가 발생한 시점까지의 시간
- 재연소 억제시간: 800℃에서 30℃ 냉각시키는데 걸리는 시간- Initial extinguishing self-sensing temperature: The temperature responded to by the microcapsule when the burner flame is sealed.
- Initial extinguishing time: The time from when the microcapsule reacts after ignition to when the flame disappears and the first smoke appears.
- Reburn suppression time: Time taken to cool from 800℃ to 30℃
상기 표 8에 나타난 바와 같이, 실시예 1 내지 4의 경우, 마이크로 캡슐의 쉘부가 열폭주로 120~350℃에 도달하여 이 온도를 감지하여 8초 내에 녹아 터져 코어내의 소화물질이 분사되고, 소화물질이 15초 이내에 800℃에서 30℃로 냉각되어 재연소를 억제하는 것을 확인하였다.As shown in Table 8, in Examples 1 to 4, the shell portion of the microcapsule reaches 120-350°C due to thermal runaway, detects this temperature, melts and bursts within 8 seconds, and the fire extinguishing agent in the core is sprayed, extinguishing the fire. It was confirmed that the material was cooled from 800°C to 30°C within 15 seconds, suppressing reburning.
반면, 비교예 1의 경우, 마이크로 캡슐의 함량이 5중량% 미만으로 인해 초기 소화시간까지 시간이 걸리며, 재연소 억제는 불가한 것을 확인하였다. 또한, 비교예 2의 경우, 마이크로 캡슐의 함량이 15중량%를 초과하여 초기 소화시간을 감소시켰으나, 도료의 점도가 상승하여 작업성이 나빠지고 건조 도막의 내구성 등 물성이 저하되는 것을 확인하였다.On the other hand, in the case of Comparative Example 1, it was confirmed that because the microcapsule content was less than 5% by weight, it took time until the initial extinguishment time, and it was impossible to suppress re-combustion. In addition, in the case of Comparative Example 2, the initial extinguishing time was reduced because the content of microcapsules exceeded 15% by weight, but it was confirmed that the viscosity of the paint increased, workability deteriorated, and physical properties such as durability of the dried coating film deteriorated.
즉, 본 발명의 지하구 초기 화재 진화용 자가 온도 감응 소화 도료 조성물은 세라믹계 무기필러인 용융알루미나, 규산지르코늄, 화성암을 고온 발포시킨 중공체, 용융실리카 및 인산아연으로 인해 건조도막의 부착력, 내화성능, 방염성능과 같은 물성을 향상시킬 수 있었으며, 120 내지 350℃의 온도에서 자가 온도 감응하는 코어-쉘 구조인 초기화재 소화용 마이크로 캡슐의 쉘부의 내구성 및 기밀성에 의해 파열, 누출하지 않고 있다가, 화재 시 화염온도를 자가감응하여 터지며 기화된 소화 조성물이 화염에 직접 분사작용하여, 연소의 4조건인 연료(가연물), 산소(공기), 열(발화원), 연쇄반응 중 열(발화원)과 연쇄반응을 끊어 주어 화재를 소화할 수 있으며, 15초 이내에 800℃에서 30℃로 냉각시켜 재연소를 억제할 수 있는 것을 확인하였다.In other words, the self-temperature sensitive fire extinguishing paint composition for extinguishing an initial fire in an underground tunnel of the present invention has a hollow body obtained by foaming fused alumina, zirconium silicate, and igneous rock as ceramic-based inorganic fillers at high temperature, fused silica, and zinc phosphate, thereby improving the adhesion of the dried coating film and fire resistance. It was possible to improve physical properties such as performance and flame resistance, and the durability and airtightness of the shell portion of the initial fire extinguishing microcapsule, which is a self-temperature-sensitive core-shell structure at a temperature of 120 to 350 ℃, does not rupture or leak. In the event of a fire, the fire extinguishing composition self-sensitizes the flame temperature and explodes, and the vaporized fire extinguishing composition is sprayed directly into the flame. It was confirmed that fires can be extinguished by stopping the chain reaction, and re-combustion can be suppressed by cooling from 800℃ to 30℃ within 15 seconds.
