본 발명의 통전기기 절연 세척제용 조성물은, 1,1-디클로로에탄(1,1-DICHLOROETHANE): 15~20 중량%, 미네랄 스피릿 66/3(MINERAL SPIRITS 66/3):55~65 중량% 및 1,1,1,2-테트라플루오로에테인(1,1,1,2-TETRAFLUOROETHANE): 18~20 중량%로 구성되어 있다.The composition for the electrical insulating machine insulation cleaner of the present invention, 1,1-dichloroethane (1,1-DICHLOROETHANE): 15 to 20% by weight, mineral spirit 66/3 (MINERAL SPIRITS 66/3): 55 to 65% by weight and 1,1,1,2-tetrafluoroethane (1,1,1,2-TETRAFLUOROETHANE): 18 to 20% by weight.
그리고 본 발명의 통전기기 절연 세척제용 조성물은, 1,1-디클로로에탄(1,1-DICHLOROETHANE): 20 중량%, 미네랄 스피릿 66/3(MINERAL SPIRITS 66/3):60 중량% 및 1,1,1,2-테트라플루오로에테인(1,1,1,2-TETRAFLUOROETHANE): 20 중량%로 구성되는 것이 바람직하다.In addition, the composition for the electrical insulating machine insulation cleaner of the present invention, 1,1-dichloroethane (1,1-DICHLOROETHANE): 20% by weight, mineral spirit 66/3 (MINERAL SPIRITS 66/3): 60% by weight and 1,1 , 1,2-tetrafluoroethane (1,1,1,2-TETRAFLUOROETHANE): It is preferably composed of 20% by weight.
이는 아래 실험예들에서 보이듯이 각각의 조성물 성분비가 상기와 같을 경우 산업용 절연파괴전압을 만족하기 때문이다.This is because, as shown in the following experimental examples, each composition component ratio satisfies the industrial breakdown voltage.
한편 본 발명의 통전기기 절연 세척제용 조성물을 제조하기 위한 방법으로써, 1,1-디클로로에탄(1,1-DICHLOROETHANE), 미네랄 스피릿 66/3(MINERAL SPIRITS 66/3) 및 1,1,1,2-테트라플루오로에테인(1,1,1,2-TETRAFLUOROETHANE)을 각각 1:1:3의 중량비가 되도록 혼합하여 제조된다.On the other hand, as a method for producing a composition for the electrical insulating machine insulation cleaning agent of the present invention, 1,1-dichloroethane (1,1-DICHLOROETHANE), mineral spirit 66/3 (MINERAL SPIRITS 66/3) and 1,1,1, 2-Tetrafluoroethane (1,1,1,2-TETRAFLUOROETHANE) is prepared by mixing to a weight ratio of 1: 1: 3, respectively.
즉, 각각의 성분들을 각각의 중량비에 맞춰 혼합기에 천천히 투입하며 툽입하는 과정에 5분간 교반이 이루어지도록 하며, 이때 상기 각각의 성분들은 모두 혼합력, 절연성 및 세척력을 포함하고 있다.In other words, each component is slowly added to the mixer according to the weight ratio, and stirring is performed for 5 minutes in the process of injecting, wherein each of the components includes mixing power, insulation and cleaning power.
한편 본 발명의 통전기기 절연 세척제용 조성물 제조방법은, 1,1-디클로로에탄(1,1-DICHLOROETHANE) 1 중량비, 미네랄 스피릿 66/3(MINERAL SPIRITS 66/3) 1 중량비 및 1,1,1,2-테트라플루오로에테인(1,1,1,2-TETRAFLUOROETHANE) 3 중량비를 각각 혼합기에 개별적으로 투입하며 5분간 교반하여 제조되는 것이 바람직하며, 20~55℃ 사이에서 이루어지는 것이 바람직하다.Meanwhile, the method for preparing a composition for an electric insulation cleaner for cleaning the present invention includes 1 weight ratio of 1,1-dichloroethane (1,1-DICHLOROETHANE), 1 weight ratio of mineral spirit 66/3, and 1,1,1. , 2-Tetrafluoroethane (1,1,1,2-TETRAFLUOROETHANE) 3 weight ratios are added to the mixer individually, and preferably prepared by stirring for 5 minutes, preferably between 20 and 55 ° C.
즉, 각각의 성분들을 모두 한번에 투입하며 교반할 수 있지만 그러할 경우 각각의 성분들이 균일하게 혼합되지 않을 우려가 있기 때문에 먼저 혼합제의 주된 성분인 1,1-디클로로에탄(1,1-DICHLOROETHANE)을 투입한 후 미네랄 스피릿 66/3(MINERAL SPIRITS 66/3)을 투입하며 5분간 교반하고, 이 후 다시 1,1,1,2-테트라플루오로에테인(1,1,1,2-TETRAFLUOROETHANE)을 투입하며 5분간 교반하는 방식으로 개별 투입과 교반을 병행하면 각각의 성분들이 균일하게 교반이 이루어질 수 있게 하는 것이 가능하다.In other words, each component can be added and stirred at the same time, but in that case, each component may not be uniformly mixed. Therefore, 1,1-dichloroethane (1,1-DICHLOROETHANE), which is the main component of the mixture, is first added. Then, mineral spirit 66/3 (MINERAL SPIRITS 66/3) was added and stirred for 5 minutes, after which 1,1,1,2-tetrafluoroethane (1,1,1,2-TETRAFLUOROETHANE) was added again. When the mixture is added and stirred in a manner of stirring for 5 minutes, it is possible to uniformly stir each component.
이를 통해 혼합된 조성물은 전압파괴증력이 증가하면서도 세척력이 우수하게 될 수 있을 뿐만 아니라 냄새 및 인체자극을 최소화할 수 있어 환경적 친화적성을 가질 수 있게 된다.Through this, the mixed composition may not only be excellent in washing power while increasing voltage breakdown force, but also may minimize odor and human irritation, thereby enabling environmental friendliness.
한 발명의 제조방법에서는 각각 교반시 온도를 20~50℃ 사이에서 이루어지게 하는 것이 바람직하다. 이는 각각의 성분들의 인화점 중 1,1-디클로로에탄(1,1-DICHLOROETHANE)의 끊는 점이 57.3℃이기 때문에 그 이하 온도에서 교반하여야 하며 일정 온도를 유지할 경우 교반시 각각의 성분들의 혼합이 더 쉽게 이루어지기 때문이다.In the production method of the invention it is preferable to make the temperature between 20 ~ 50 ℃ each stirring. This is because the break point of 1,1-dichloroethane (1,1-DICHLOROETHANE) of each component is 57.3 ° C, so it must be stirred at a temperature below that. For losing.
이하, 각각의 성분들을 혼합비율을 달리하여 실험한 실험예를 통해 본 발명을 설명하도록 한다.Hereinafter, the present invention will be described through experimental examples in which each component is mixed at different mixing ratios.
여기서 본 발명의 실험예는 한국석유관리원(Kpetro)을 통해 실험한 것으로 실험방법은 KS C IEC 60156:2003에 의해 이루어졌다. 또한 실험예에서는 성분의 조성비율에 따른 절연파괴전압결과치, ODC규제물질 유/무, 인화점 및 세척력의 변화를 실험하였다.Here, the experimental example of the present invention was conducted through the Korea Petroleum Management Institute (Kpetro), the test method was made by KS C IEC 60156: 2003. In the experimental example, the results of dielectric breakdown voltage, ODC regulatory substance presence / absence, flash point and cleaning power were tested according to the composition ratio of the component.
또한 본 실험예들에서는 1,1-디클로로에탄(1,1-DICHLOROETHANE), 미네랄 스피릿 66/3(MINERAL SPIRITS 66/3) 및 1,1,1,2-테트라플루오로에테인(1,1,1,2-TETRAFLUOROETHANE) 각각을 1:1:3의 중량비로 혼합된 것을 기초로 하였다.In addition, in the present experimental examples, 1,1-dichloroethane (1,1-DICHLOROETHANE), mineral spirit 66/3 and 1,1,1,2-tetrafluoroethane (1,1, 1,2-TETRAFLUOROETHANE) were each mixed at a weight ratio of 1: 1: 3.
*주1) 본 실험예에서의 세척력 테스트는 테스트용 배전반을 일정량 오염시킨 후 본 조성물을 분사하였을 때 오염된 표면의 오염원 제거 정도를 나타낸 것으로 세척력의 정도는 우수, 좋음, 낮음, 매우 낮음으로 표시하였으며, 각각의 실험예 사용되는 오염물은 기름 성분을 포함한 미세먼지를 이용하였으며, KS C 2101:2006의 방법을 이용하였다.* 1) The cleaning power test in this Experimental Example shows the degree of removal of contaminants on the contaminated surface when the composition was sprayed after a certain amount of contamination on the test switchboard. In each experiment, contaminants used were fine dust including an oil component, and the method of KS C 2101: 2006 was used.
*주2) 본 실험예에서의 인화점 테스트는 테스트용 배전반이 주로 산업용 고전압에 이용되는 것을 감안하여 테스트하였으며 테스트용 배전반의 온도를 상승시켰을 때의 인화 온도를 표시하였으며, KS M ISO 2719;2003의 방법을 이용하였다.* 2) The flash point test in this test example was conducted in consideration of the fact that the test switchgear is mainly used for industrial high voltage, and displayed the flash temperature when the temperature of the test switchgear was increased, and according to KS M ISO 2719; 2003. Method was used.
한편 본 실험예들에서는 테스트용 배전반은 안전을 위하여 통전된 상태와 통전되지 않은 상태를 구분하였다.On the other hand, in the test examples, the test switchboard distinguished between the energized state and the non-energized state for safety.

이하, 미네랄스피릿66/3은 "M"으로, 1,1-디클로로에탄은 "D"로, 1,1,1,2-테트라플루오에테인은 "T"로 표시한다.Hereinafter, mineral spirit 66/3 is represented by "M", 1,1-dichloroethane is represented by "D", and 1,1,1,2- tetrafluoroethane is represented by "T".
실험예 1에 의해 나타난 표 1의 결과를 보면, M과 T의 함유량은 많고 D의 함유량이 적을 경우 세척력은 우수한 것으로 나타나지만 배전반의 절연파괴전압은 측정 불가로 나타나고 인화점은 대체로 높게 형성됨을 알 수 있다. 이를 볼 때 실험예 1의 조성비를 가질 경우 배전반의 세척에는 유리하나 배전반의 특성상 절연상태를 항상 유지해야 한다는 점 감안할 때에 절연 세척제로써의 이용은 불가능할 것으로 보인다.In the results of Table 1 shown by Experimental Example 1, when the content of M and T is high and the content of D is low, the cleaning power appears to be excellent, but the breakdown voltage of the switchboard appears to be unmeasurable and the flash point is generally formed high. . In view of this, the composition ratio of Experimental Example 1 is advantageous for cleaning the switchboard, but considering that the insulation state should always be maintained due to the characteristics of the switchboard, it may not be used as an insulation cleaner.

실험예 2에 의해 나타난 표 2의 결과를 보면, D의 조성비를 높일 경우 절연파괴전압 수치는 상당히 높게 나오지만 상대적으로 인화점이 낮게 형성되어 배전반의 사용 특성상 실험예 3의 조성물로 세척제를 이용할 경우 세척제에 의해 배전반의 화제 등으로 이어질 수 있어 세척제로써의 이용에는 어려움이 있을 것으로 보인다.In the results of Table 2 shown by Experimental Example 2, when the composition ratio of D is increased, the dielectric breakdown voltage value is quite high, but the flash point is formed relatively low, so when the cleaning agent is used as the composition of Experimental Example 3 due to the characteristics of the switchboard, This may lead to the topic of the switchboard, so there is a difficulty in using as a cleaning agent.
예컨대 통전기기, 특히 산업용 배전반 등의 경우 사용되는 전압이 매우 높고 이로 인해 발생되는 열 또한 높기 때문에 절연파괴전압 및 인화점 등이 일정 부분 유지되어야 하므로 실험예 1의 경우 세척력은 우수하나 절연파괴전압을 측정할 수 없을 정도로 절연성을 유지할 수 없었고, 실험예 3의 경우 절연파괴전압과 세척력은 우수하나, 인화점이 상대적으로 낮게 형성되어 고전압기 흐르는 경우 화재로 이어질 수 있는 단점이 있어 통전기기용 절연 세척제로 이용하는데에는 어려움이 있고, 실험예 2의 경우 실험예 1과 3에 비하여 상대적으로 낮은 세척력을 보이지만 절연파괴전압 및 인화점이 상대적으로 높게 형성되어 있어 고전압이 흐르는 통전기기용 절연 세척제로서 매우 우수한 것으로 보인다.For example, in case of an electric machine, especially an industrial switchboard, the voltage used is very high and the heat generated by it is also high. Therefore, the breakdown voltage and the flash point must be kept to a certain degree. Insulation could not be maintained to the extent that it could not, and in the case of Experiment 3, the insulation breakdown voltage and washing power are excellent, but the flash point is formed relatively low, which can lead to fire when flowing high voltage. It is difficult to do this, and Experimental Example 2 shows relatively low cleaning power compared to Experimental Examples 1 and 3, but the insulation breakdown voltage and flash point are formed relatively high, and thus, it appears to be very excellent as an insulation cleaner for an electric current flowing through a high voltage.
