It relates to a flame retardant composition comprising a capsule and a digestive material.
기술의 발전으로 인해 전기를 사용하는 다양한 기계들, 예를 들어 가전제품이나 공장에서 사용하는 로봇들이 다수 사용되고 있으며, 이에 동력을 제공하는 전기의 중요성이 부각되고 있다.Due to the development of technology, various machines that use electricity, for example, a number of robots used in home appliances or factories are used, and the importance of electricity that provides power is highlighted.
이러한 전기를 일반 가정까지 전달되는 과정은 예를 들어, 발전소 - 1차 변전소 - 2차 변전소 - 자가용 변전실 - 수전반 - 변압기 - 배전반 - 동별분전반 - 계량기함 - 세대 분전반을 통해 각 가정으로 전달된다.The process of transferring this electricity to the general household is delivered to each home through, for example, a power plant-primary substation-secondary substation-private substation-power reception panel-transformer-switchboard-copper distribution panel-meter box-household distribution panel.
상기 수전반(受電盤)은 말 그대로 전기를 받는 패널로서, 수전반은 변압기 이전의 패널이고, 그리고 배전반(配電盤)은 전기를 나누어 주는 패널로서, 배전반은 변압기 이후의 패널이다.The power receiving panel is a panel that literally receives electricity, the power receiving panel is a panel before the transformer, and the power distribution panel is a panel for dividing electricity, and the switchboard is a panel after the transformer.
이러한 수전반 및 배전반(이하, ‘수배전반’이라 함)은 과전류나 과부하 또는 단락 등에 의하여 전기 과열로 화재 발생의 위험이 내재되어 있다. The risks of fire due to electric overheating due to overcurrent, overload, or short circuit are inherent to these switchboards and switchboards (hereinafter referred to as “receiving switchboards”).
수배전반의 화재로 인한 고장은 현대 사회에 없어서는 안 되는 전기의 공급이 끊김을 의미하며, 이로 인한 경제, 사회적 손실이 막대하다고 할 수 있다. A breakdown caused by fire in the switchboard means that the supply of electricity, which is indispensable to modern society, is cut off, and it can be said that the economic and social losses caused by this are enormous.
따라서, 이러한 수배전반의 화재 발생에 대비하여 수배전반 내에 열감지기와 연기감지기 등이 장착되고, 외부로부터 소화약제, 예를 들어, 하론(HALON)이나 이산화탄소(CO2) 등이 분사되는 분사노즐이 구비되어 있다.Therefore, in preparation for the fire of the switchgear, a heat detector and a smoke detector are installed in the switchgear, and an injection nozzle for spraying an extinguishing agent, for example, HALON or carbon dioxide (CO 2 ), is provided from the outside. have.
수배전반은 내부의 소정 공간에 상술한 수전반 및 배전반의 내부 구성요소가 설치되고, 다수의 수배전반이 좌우로 인접되게 나열되며, 수배전반 상면에는 소화약제와 분사노즐 및 이를 연결하는 공급배관이 설치된다.The switchboard is provided with the above-described switchboard and the internal components of the switchboard in a predetermined space therein, and a plurality of switchboards are arranged to be adjacent to the left and right, and a fire extinguishing agent, a spray nozzle and a supply pipe connecting them are installed on the upper surface of the switchboard.
그러나, 각 수배전반 마다 소화용 설비가 구비되어 화재 발생 시에 “화재의 인식 - 소화약제의 분사” 순서로 소화절차가 이루어지기 때문에, 화재를 인식하는 센서와 소화약제를 분사하는 설비에 대한 관리비용이 상승함은 물론, 각각의 소화약제로부터 분사노즐을 연결하는 공급배관이 각각 설치되어 그 설계가 복잡하고, 화재를 인식하는 센서의 고장 시 이를 사용자가 인식하기 쉽지 않은 문제점이 있었다.However, since the fire extinguishing equipment is provided for each switchgear, the fire extinguishing procedure is performed in the order of “recognition of fire-spraying of fire extinguishing agent” in the event of a fire. This rise, of course, has a problem in that the design of the supply pipe connecting the injection nozzles from each extinguishing agent is complicated, and it is not easy for the user to recognize when the sensor that recognizes the fire breaks down.

또는, 상술한 몬모릴로나이트, 사포나이트, 헥토라이트, 바이델라이트, 스티분사이트, 논트로나이트, 질석, 할로이사이트 및 팽윤성 마이카로 이루어진 군으로부터 선택된 1종 이상의 기체 차단성 물질을 더 포함할 수 있다.Or, it may further include at least one gas barrier material selected from the group consisting of the above-described montmorillonite, saponite, hectorite, videlite, stybunsite, nontronite, vermiculite, halosite and swellable mica.
또한, 상기 소화물질이 포함된 캡슐을 포함하는 난연성이 향상된 조성물에 포함되는 소화물질이 포함된 캡슐은 고분자 수지 100 중량부에 대하여 10 ~ 50 중량부 포함될 수 있으며, 10 중량부 미만으로 포함시 화재를 방지하는 충분한 효과를 얻지 못할 수 있고, 50 중량부를 초과하게 되면 코팅시 접착성이 떨어져 코팅층이 박리되는 문제가 발생될 수 있다.In addition, the capsule containing the extinguishing agent contained in the composition having improved flame retardancy, including the capsule containing the extinguishing agent may be included in an amount of 10 to 50 parts by weight based on 100 parts by weight of the polymer resin, and when included in less than 10 parts by weight, fire It may not be possible to obtain a sufficient effect to prevent, if it exceeds 50 parts by weight may cause a problem that the coating layer is peeled off the adhesion during coating.
일 예로, 본 발명의 소화물질이 포함된 캡슐을 포함하는 난연성이 향상된 조성물이 코팅대상이 되는 표면 즉, 기재상에 도포되어 코팅층을 형성할 수 있으며, 상기 코팅층 내 소화물질이 포함된 캡슐이 포함된다.For example, a flame retardant composition comprising a capsule containing the extinguishing agent of the present invention may be coated on a surface to be coated, that is, a substrate to form a coating layer, and the capsule containing the extinguishing agent in the coating layer is included. do.
이로써, 상기 코팅층은 평상시에는 대상 구조 표면을 보호하는 역할을 하다가, 화재가 발생되어 소정의 온도 이상으로 주변 온도가 상승하게 되면 상기 코팅층 내부의 소화물질이 포함된 캡슐의 쉘이 와해되어 상기 소화물질이 포함된 코어가 외부로 방출됨으로써 불꽃과 가연물 사이의 방벽 역할을 하여 초기에 화재를 진압하거나 화재가 번지는 것을 예방할 수 있다.Thus, the coating layer serves to protect the surface of the target structure at normal times, and when a fire occurs and the ambient temperature rises above a predetermined temperature, the shell of the capsule containing the extinguishing material inside the coating layer breaks down to extinguish the extinguishing material. By discharging the core therein to the outside, it acts as a barrier between the flame and the combustible material, thereby suppressing the fire at an early stage or preventing the fire from spreading.
일반적으로 시중에 널리 사용중인 난연성 조성물의 경우, 고분자 수지에 난연성 효과가 있는 물질, 유기안료 및/또는 무기안료를 포함하는 충진제, 적하 방지제, 가소제, 열안정제, 산화방지제, 광안정제, 상용화제, 염료, 침강방지제 및 분산제 등등 각종 물질이 혼합되어 제조되고, 이러한 일반적인 난연성 를 사용하여 코팅시, 난연성 효과가 있는 물질로 인하여 본래의 목적인 코팅대상인 구조 표면에 완벽히 부착되지 않아 보호효과가 떨어질 우려가 있을 뿐만 아니라, 시간이 경과함에 따라 코팅물 내 포함된 각종 물질 간의 화학 반응 또는 외부에서 유입되는 외부인자로 인하여 난연성 효과가 있는 물질의 물리적 성질이 변화하거나 기능이 저하되는 문제가 있었다.In general, in the case of a flame retardant composition widely used in the market, a filler, a dropping agent, a plasticizer, a heat stabilizer, an antioxidant, a light stabilizer, a compatibilizer, a material having a flame retardant effect on a polymer resin, an organic pigment and/or an inorganic pigment, Various materials such as dyes, anti-settling agents, dispersants, etc. are manufactured by mixing, and when coating using these general flame retardants, there is a concern that the protective effect may deteriorate due to the fact that the flame retardant materials do not adhere perfectly to the structure surface of the original target coating object. In addition, there is a problem that a physical property of a material having a flame retardant effect changes or a function is deteriorated due to a chemical reaction between various substances included in the coating or an external factor introduced from the outside with time.
그러나, 본 발명의 소화물질이 포함된 캡슐을 포함하는 난연성이 향상된 조성물의 경우, 연소반응을 종결시키기 위하여 산소공급을 차단하거나, 가연물을 냉각시키거나, 연소반응이 연쇄적으로 일어나게 하는 물질을 비활성화시킬 수 있는 소화물질이 합성 수지로 인하여 코팅되어 있어 외부와의 접촉이 차단되어 시간이 경과되어도 상기 소화물질의 물성이 변화되거나 활성이 저하되는 우려가 적을 뿐만 아니라, 조성물 내 포함시에도 각종 물질 간의 화학적 반응을 저감시켜 저장안정성, 화학적 안정성이 뛰어나다.However, in the case of a composition having improved flame retardancy comprising a capsule containing the extinguishing agent of the present invention, an oxygen supply is blocked in order to terminate a combustion reaction, a combustible material is cooled, or a substance that causes a combustion reaction to occur in a chain is deactivated. The fire extinguishing agent that can be coated is coated with synthetic resin, so that contact with the outside is blocked and there is less concern that the physical properties of the fire extinguishing material may change or the activity deteriorate over time. It has excellent storage stability and chemical stability by reducing chemical reactions.
따라서, 본 발명의 소화물질이 포함된 캡슐을 포함하는 난연성이 향상된 조성물을 사용하여 코팅하여 코팅층을 형성하게 되면, 평상시에는 대상 구조 표면을 보호하는 역할을 하다가, 화재가 발생되어 소정의 온도 이상으로 주변 온도가 상승하게 되면 상기 코팅층 내부의 소화물질이 포함된 캡슐의 쉘이 와해되어 상기 소화물질이 외부로 방출됨으로써 불꽃과 가연물 사이의 방벽 역할을 하여 초기에 화재를 진압하거나 화재가 번지는 것을 예방할 수 있다.Therefore, when a coating layer is formed by coating using a composition having improved flame retardancy including a capsule containing the extinguishing agent of the present invention, it usually serves to protect the target structure surface, and then a fire is generated to exceed a predetermined temperature. When the ambient temperature rises, the shell of the capsule containing the extinguishing agent inside the coating layer breaks down, and the extinguishing agent is released to the outside, thereby acting as a barrier between the flame and the combustible material. Can.
