본 발명은 유기 용제 누설 감지 장치에 관한 것으로, 특히 누설되는 유기 용제에 반응하여 저항값이 변화됨으로써 유기 용제의 누설 상태를 감지하도록 한 유기 용제 누설 감지 장치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an organic solvent leakage detecting apparatus, and more particularly, to an organic solvent leakage detecting apparatus which detects a leakage state of an organic solvent by changing a resistance value in response to a leakage organic solvent.

본 출원인은 이미 여러 건의 등록 특허(10-0909242, 10-0827385 등)에서 테이프 형태로 되어 누수가 발생하기 쉬운 위치에 설치함으로써 누수 발생을 쉽게 감지할 수 있도록 하는 테이프 형태의 누수감지센서를 제안한 바 있다.The applicant of the present invention has already proposed a tape-like leak detection sensor that can easily detect the occurrence of leakage by providing a tape-like shape in a number of registered patents (10-0909242, 10-0827385, etc.) have.

도1 및 도2에 도시한 바와 같이 이러한 누수감지센서(100)는 하부접착층(120), 베이스필름층(110), 상부보호필름층(130)이 저면에서 상방으로 순차적으로 적층되어 이루어진다.1 and 2, the leak sensor 100 includes a lower adhesive layer 120, a base film layer 110, and an upper protective film layer 130 sequentially stacked on the bottom surface.

하부접착층(120)은 누수가 발생되는 곳에 부착하기 위한 것으로, 접착 테이프 형태로 구성되고, 베이스필름층(110)은 도전라인(111,112)이 상부에 형성되기 위한 층으로서, 도전라인(111,112)의 패턴을 인쇄 방식에 형성하기 위해 PET, PE, PTFE, PVC 또는 기타 테프론 계열의 재질의 필름으로 형성된다.The base film layer 110 is a layer in which the conductive lines 111 and 112 are formed on the upper part and the upper part of the conductive lines 111 and 112 It is formed of a film made of PET, PE, PTFE, PVC or other Teflon series to form a pattern in a printing method.

그리고, 도전라인(111,112)은 베이스필름층(110)의 상부표면에서 서로 이격되어 길이방향으로 평행하게 스트립 형태로 배치되며, 도전성 잉크 또는 은(Silver) 화합물로 인쇄된다.The conductive lines 111 and 112 are arranged in strips parallel to each other in the longitudinal direction, spaced from each other on the upper surface of the base film layer 110, and printed with a conductive ink or silver compound.

상부보호필름층(130)은 베이스필름층(110)의 상부에 적층되어 도전라인(111,112)을 외부의 자극으로부터 보호하기 위한 층으로서, 베이스필름층(110)과 같이 PET, PE, PTFE, PVC 또는 기타 테프론 계열의 재질로 형성되며, 도전라인(111,112)에 해당하는 위치에 일정간격마다 센싱홀(131)이 관통되어 형성되도록 구성된다.The upper protective film layer 130 is a layer for protecting the conductive lines 111 and 112 from external stimuli by being laminated on the base film layer 110. The upper protective film layer 130 may be made of PET, Or other Teflon-based materials. The sensing holes 131 are formed at predetermined intervals in positions corresponding to the conductive lines 111 and 112, respectively.

따라서, 누수가 발생하면, 누수가 발생된 위치의 센싱홀(131)을 통해 수분이 유입되어 두 도전라인(111,112)이 수분에 의해 통전되며, 원격의 제어기가 그 통전상태 즉 폐회로가 형성되는 상태를 파악하여 누수여부를 감지하고, 그에 따른 경보를 발생할 수 있게 된다.Therefore, when water leakage occurs, water is introduced through the sensing hole 131 at the position where the water leakage occurs, so that the two conductive lines 111 and 112 are energized by moisture, and the state of the remote controller in the energized state So that it is possible to detect the leakage and to generate an alarm accordingly.

그런데, 이러한 종래의 필름형 누수감지센서(100)는 도전성을 가져서 도전성 용액의 누설을 검출할 수 있지만, 윤활유, 작동유, 절연유, 휘발유, 경유, 등유, 항공유 등의 각종 오일류, 노말핵산, 디클로로에틸렌(이염화아세틸렌), 디클로로에탄(이염화에틸렌), 메타놀, 사염화탄소, 아세톤, 오르토-디클로로벤젠, 이황화탄소, 초산메틸, 크실렌, 클로로벤젠, 클로로포름, 테트라클로로에탄(사염화아세틸렌), 테트라클로로에틸렌(파-클로로에틸렌), 톨루엔, 트리클로로에틸렌, 기타 석유화학 합성물 등의 유기 용제만을 선택적으로 검출할 수 없는 문제점이 있다.
However, the conventional film type leak sensor 100 may have conductivity and can detect the leakage of the conductive solution. However, the conventional film type leak sensor 100 can detect leakage of the conductive solution, but it is also possible to use various oil such as lubricating oil, operating oil, insulating oil, gasoline, light oil, kerosene, (Acetylene dichloride), dichloroethane (ethylene dichloride), methanol, carbon tetrachloride, acetone, ortho-dichlorobenzene, carbon disulfide, methyl acetate, xylene, chlorobenzene, chloroform, tetrachloroethane, tetrachlorethylene And organic solvents such as toluene, trichlorethylene, and other petrochemical compounds can not be selectively detected.

본 발명을 첨부한 도면을 참조하여 상세히 설명한다.The present invention will be described in detail with reference to the accompanying drawings.

도3은 본 발명에 적용된 유기용제 누설 감지 센서(200)의 구조를 보인 도로서, PET, PE, PTFE, PI, PVC 또는 기타 테프론 계열의 필름 재질로 된 베이스필름층(210)과, 상기 베이스필름층(210)의 상측에 적층되는 상부보호필름층(230)로 구성된다.3 is a view showing a structure of an organic solvent leakage sensor 200 applied to the present invention. The base film layer 210 is made of PET, PE, PTFE, PI, PVC or other Teflon series film material, And an upper protective film layer 230 laminated on the upper side of the film layer 210.

베이스필름층(210)의 상부면에는 한 쌍의 도전라인(211,212)이 서로 이격되어 길이방향으로 평행하게 스트립 형태로 배치되며, 이러한 도전라인(211,212)은 유기 용제에 반응하여 저항값이 변화되는 물질로 형성된다.On the upper surface of the base film layer 210, a pair of conductive lines 211 and 212 are arranged in strips parallel to each other in the longitudinal direction. The conductive lines 211 and 212 are formed in such a manner that the resistance value is changed in response to the organic solvent Lt; / RTI >

이를 위해 도전라인(211,212)은 액티브 카본 또는 탄소 나노 튜브(Carbon Nano Tube) 또는 그래핀(Graphene) 또는 카본 블랙(Carbon black) 등의 도전성을 갖는 전도성 카본 50~90 중량%에 바인더로서 알키드 수지가 5~30 중량%, 그리고 POSS(Polyhedral Oligomeric Silsequioxane) 고분자 화합물이 5~20 중량%가 혼합되어 전도성 카본 잉크가 조성되고, 그 전도성 카본 잉크로 그라비아 인쇄방식, 실크 스크린 인쇄방식, 잉크젯 인쇄방식 등의 다양한 인쇄방식에 의해 베이스필름층(210)에 인쇄하여 도전라인(211,212)을 형성하게 된다. To this end, the conductive lines 211 and 212 are made of conductive carbon having a conductivity of 50 to 90% by weight, such as active carbon or carbon nano tube (Carbon Nano Tube) or graphene or carbon black, 5 to 30% by weight of a conductive carbon ink and 5 to 20% by weight of a polyhedral oligomeric silsequioxane (POSS) polymer compound are mixed to form a conductive carbon ink. The conductive carbon ink is mixed with a conductive carbon ink by a gravure printing method, a silk screen printing method, The base film layer 210 is printed by various printing methods to form the conductive lines 211 and 212.

아울러 알키드 수지의 분산제로서 MEK(Methyl Ethyl Ketone) 용매가 더 포함되는데, 이러한 MEK 용매는 알키드 수지 5~30 중량% 내에 3~15 중량%가 포함되어 있다.Further, MEK (Methyl Ethyl Ketone) solvent is further included as a dispersant of the alkyd resin, and the MEK solvent contains 3 to 15 wt% in 5 to 30 wt% of the alkyd resin.

또한, 상부보호필름층(230)은 PC, PP, PE, PI, PET, 테프론 재질 등의 합성수지재로 50~300㎛ 두께로 형성되며, 도전라인(211,212)이 형성된 위치에 센싱홀(231)이 형성된다.The upper protective film layer 230 is formed of a synthetic resin material such as PC, PP, PE, PI, PET, Teflon or the like to have a thickness of 50 to 300 탆 and has a sensing hole 231 at a position where the conductive lines 211 and 212 are formed. .

따라서, 유기 용제의 누설이 발생하면, 누설이 발생된 위치의 센싱홀(231)을 통해 유기 용제 용액이 유입되어 알키드 수지가 분해되면서 도전라인(211,212)의 저항값이 변화하게 되는데, 이때 유기 용제에 반응하여 저항값이 변화되는 물질인 POSS(Polyhedral Oligomeric Silsequioxane) 고분자 화합물의 세공(細孔)(pore) 구조에 유기 용제가 유입되어 저항이 더욱 빠르게 변화된다.Therefore, when leakage of the organic solvent occurs, the organic solvent solution flows into the sensing hole 231 at the position where the leakage occurs, and the alkyd resin is decomposed to change the resistance value of the conductive lines 211 and 212. At this time, The resistivity is changed more rapidly because the organic solvent flows into the pore structure of the polyhedral oligomeric silsequioxane (POSS) polymer, which is a substance whose resistance value changes in response to the reaction of the organic solvent.

즉, 바인더로서 알키드 수지만 사용한 경우에 유기 용제에 의해 전도성 카본의 배열이 무너지기 까지는 오랜 시간이 소요되지만, POSS의 세공에 유기용제가 유입되면 더욱 빠르게 저항값의 변화를 가져오므로 그 감지 시간이 매우 짧아 센싱의 감도가 매우 좋아지게 된다.That is, when alkyd resin alone is used as the binder, it takes a long time until the arrangement of the conductive carbon is collapsed by the organic solvent. However, when the organic solvent flows into the pores of the POSS, the resistance value changes more quickly, Is very short, the sensitivity of the sensing becomes very good.

따라서, 원격의 제어기가 그 도전라인(211,212)의 저항값 변화를 제공받아 유기 용제의 누설 여부를 확인할 수 있는 것이다.
Therefore, the remote controller can receive a change in the resistance value of the conductive lines 211 and 212 to confirm whether or not the organic solvent has leaked.

도4는 이러한 유기용제의 누설 여부를 확인하기 위한 전체 시스템을 보인 도로서, 도5(a)에 도시한 바와 같이 유기용제 누설 감지 센서(200)의 양단에 스타트 커넥터(400)와 엔드 커넥터(500)가 연결되는데, 스타트 커넥터(400)는 제어기(300)와 연결되고, 엔드 커넥터(500)는 유기용제 누설 감지 센서(200)의 끝단에서 도전라인(211,212)을 연결하는 커넥터이다.4 (a), the start connector 400 and the end connector (not shown) are provided at both ends of the organic solvent leakage sensor 200 as shown in FIG. 5 (a) The start connector 400 is connected to the controller 300 and the end connector 500 is a connector for connecting the conductive lines 211 and 212 at the ends of the organic solvent leakage sensor 200.

도4(b)는 제2도전라인(212)이 유기 용제에 반응하여 저항값이 변화되는 물질로 형성되고, 제1도전라인(211)은 도전체로 형성된 경우를 예로 든 회로도로서, 유기 용제의 누설이 발생하여 센싱홀(231)을 통해 유입되어 제2도전라인(212)과 접촉되면, 제2도전라인(212)의 저항값 변화가 발생하며, 이로 인해 원격의 제어기(300)는 유기 용제의 누설을 확인할 수 있는 것이다.

A leakage occurs and flows through the sensing hole 231 and comes into contact with the second conductive line 212 to cause a change in the resistance value of the second conductive line 212.
