제1도 정격 500V.150㎌이며 사이즈 35
제2도는 본 발명의 다른 실시예로 정격 400V.39㎌이며 사이즈 35
본 발명은 중고전압(中高電압) 전해액에 관한 것으로, 상세하게 설명하면 동작전압이 100V를 초과하는, 특히 알루미늄 전해콘덴서 구동용(駒動用)의 중고전압 전해액에 관한 것이다.BACKGROUND OF THE
종래, 당업계에서 알려져 있는 상기한 종류의 중고압전해액은, 그 용매(溶媒)로서 에틸렌글리콜이나 글리세린 등 다가(多
중고 전압의 전해액은 안전성의 면에서, 특히 내전압성이 높은 것이 요구 되고 있다.In terms of safety, high and medium voltage electrolytes are required to have particularly high withstand voltage.
상기한 바와 같은 용매계를 사용한 종래의 전해액인 경우, 중고전압(특히 500V라는 고전압)이 되면 신틸레이션(scintillation)이 급격히 증대하여(내전압 부족), 이와같은 전압에서 사용하면 누설전류(leakage current)가 높아져서 쇼트되는 일이 있으며, 더우기 가스발생을 수반하여 내압상승을 초래하는 등의 결점을 갖고 있다.In the case of the conventional electrolyte solution using a solvent system as described above, scintillation rapidly increases when the medium voltage (especially a high voltage of 500V) increases (lack of withstand voltage), and when used at such a voltage, the leakage current is increased. It may become high and short, and also has the drawback of causing a rise in pressure with the generation of gas.
따라서, 동작전압이 160V를 초과하는 중고전압에서 사용되는 전해액, 특히 알루미늄 전해콘덴서 구동용의 전해액에 있어서는, 상기한 용매계에 수반되는 결점을 해소하기 위한 개선이 강하게 요망되고 있다.Therefore, in the electrolyte used at a high voltage exceeding 160V, especially an electrolyte for driving an aluminum electrolytic capacitor, there is a strong demand for improvement to solve the drawbacks associated with the above solvent system.
한편, 예를들어 각종 라텍스(latex)의 개질(改質), 섬유의 윤활, 유연화, 세탁시의 역오염방지, 혹은 화장품용 첨가제(샴프, 린스 등)의 분야에서는, 각종의 실리콘오일이나 그것의 개질 실리콘오일이 사용되고 있다.On the other hand, in the fields of, for example, the modification of various latexes, the lubrication and softening of fibers, the prevention of back contamination during washing, or the additives for cosmetics (shampoo, rinse, etc.), various silicone oils and the like Modified silicone oil is used.
통상, 실리콘오일은 아래의 식In general, the silicone oil is
으로 표시되는 주구조를 보유하며, 그것의 일반적인 성질은 다음과 같은 우수한 특성을 갖고 잇다.It has the main structure indicated by, and its general property has the following excellent characteristics.
(1) 내열성 : 200∼250℃에 견딘다.(1) Heat resistance:
(2) 내한성 : -50∼70℃에서도 특성을 유지한다.(2) Cold resistance: Maintains characteristics even at -50 ~ 70 ℃.
(3) 특이한 계면할성 : 낮은 표면 장력, 발수성(撥水性), 이형성(離型性), 윤활성, 소포성(消泡性).(3) Unusual interfacial properties: low surface tension, water repellency, mold release property, lubricity, anti-foaming property.
(4) 높은 화학적, 물리적 안정성(4) high chemical and physical stability
(5) 우수한 전기 특성(5) excellent electrical properties
그러나, 실리콘오일은, 상기한바와 같은 특이한 성질이 있음에도 불구하고, 그 불활성이라는 성질 때문에 종래 전해액의 용매계인 에틸렌글리콜, 글리세린, 부티롤락톤(butyrolactone), 디메틸 포름 아미드등과 혼화(混和)되지 않아, 첨가 사용이 불가능하다.However, the silicone oil, despite its specific properties as described above, is incompatible with ethylene glycol, glycerin, butyrolactone, dimethyl formamide, and the like, which are solvent-based solvents of conventional electrolytes because of its inert properties. It is not possible to add or use.
따라서, 본 발명의 주요한 목적은, 중고 전압하에서의 사용에 있어서도 신틸레이션이 적어 LC값이 저감되며, 또 내압적으로도 우수한 알루미늄 전해콘덴서 구동용의 중고 전압 전해액을 제공함에 있다.Accordingly, a main object of the present invention is to provide a medium voltage electrolyte solution for driving an aluminum electrolytic capacitor, which has a low scintillation even when used under a medium voltage, which reduces LC value and is excellent in pressure resistance.
이때, 상기한바와 같은, 실리콘오일의 특이한 성질을 감안하여, 이것을 중고전압용 전해액에 첨가사용하면, 알루미산화 피막과 전해액과의 경계면에 신규한 형상을 초래할 가능성이 있는 것을 알아내고 또, 실리콘오일의 주쇄(主鎖)에 친수성기를 도입하면(소위 유기변성 실리콘오일), 에틸렌글리콜이나 글리세린 등 다른 용매와의 상용성(相溶性)이 높아지며, 따라서, 이들의 용매계에 첨가사용하여, 상기한 목적을 달성할 수 있음을 규명하였다.At this time, in consideration of the specific properties of the silicon oil as described above, it is found that the addition and use of the electrolyte in the medium and high voltage electrolyte may cause a new shape on the interface between the aluminized film and the electrolyte. The introduction of a hydrophilic group into the main chain of the so-called (so-called organic modified silicone oil) increases the compatibility with other solvents such as ethylene glycol and glycerin, and thus it is added to these solvent systems and used as described above. It was found that the objective could be achieved.
본 발명에 의한 알루미늄 전해 콘덴서 구동용의 중고 전압전해액은, 그 용매에 친수성 실리콘오일을 첨가하는 것을 특징으로 한다.The medium voltage electrolyte for driving an aluminum electrolytic capacitor according to the present invention is characterized by adding a hydrophilic silicone oil to the solvent.
실리콘오일을 친수성하는 하는 데는, 아래식To make hydrophilic silicone oil,
의 실리콘 골격구조(주쇄)에 친수성수식기로서, 수산기, 카드복실기, 에폭시기, 폴리에테르기 등을 도입할 수가 있다.As a hydrophilic formula group, a hydroxyl group, a cardbox group, an epoxy group, a polyether group, etc. can be introduce | transduced into the silicone skeleton structure (backbone) of the compound.
실리콘 주쇄에 대한 이들 친수성기의 도입은, 실리코오일업계에서 주지된 방법에 따라서 실시할수 가 있다.Introduction of these hydrophilic groups to the silicone backbone can be carried out according to methods well known in the silicone oil industry.
예를들어, 화장품업계, 섬유업계 등의 분야에서는, 각종의 유기변성 실리콘오일이 사용되고 있으며, 그 제조방법도 알려져 있다.For example, various organic modified silicone oils are used in the fields of the cosmetics industry and the textile industry, and the manufacturing method thereof is also known.
본 발명에 있어서는, 친수성을 실리콘오일에 부여한다는 관점에서 아래식In the present invention, in view of imparting hydrophilicity to silicone oil,
의 알코올 변성형, 또는 아래식Alcohol modification, or
의 폴리에테르 변성형, 또는 아래식Polyether modified form of formula, or
의 폴리옥시, 폴리에테르 변성형(상기한 식중, X 및 Y는 각각 정수이고, R는 -CH3, -CH2CH3또는 를 표시하며, R1및 R2는 알킬기이고, POA는 폴리옥시알킬렌, 폴리에 틸렌옥시드, 또는 폴리프로필렌옥시드를 표시함) 등, 유기변성 실리콘오일을 사용하면 바람직하다.Polyoxy, polyether-modified form (wherein X and Y are each an integer, R represents -CH 3 , -CH 2 CH 3 or, R 1 and R 2 is an alkyl group, POA is a polyoxy It is preferable to use an organic modified silicone oil, such as alkylene, polystyrene oxide, or polypropylene oxide).
이들의 변성방법도 실리콘오일 업계에 있어서는 주지되어 있다.These modification methods are also well known in the silicon oil industry.
전해액에 대한 친수성 실리콘오일의 첨가량은 0.5∼15 중량 % 정도로하면 본 발명의 목적으로서는 충분하다.The amount of the hydrophilic silicone oil added to the electrolyte is about 0.5 to 15% by weight, which is sufficient for the purposes of the present invention.
본 발명에 의하여, 전해액의 용매(예를 들어, 에틸렌글리콜)에 대하여 친수성 실리콘오일을 첨가하면, 중고전압하(특히, 500V)에 있어서도 신틸이선 및 LC값을 낮게 억제할 수 있어서, 내압성도 향상된다.According to the present invention, when hydrophilic silicone oil is added to a solvent of an electrolyte solution (for example, ethylene glycol), the scintillary line and LC value can be suppressed low even under a high voltage (especially 500 V), so that the pressure resistance is also high. Is improved.
더우기, 중고전압하에서의 화성성(化成性)이 상당히 개선됨과 아울러, 수명 특성도 실리콘오일 특유의 계면활성에 의하여 향상된다.Moreover, the chemical conversion under high and medium voltage is considerably improved, and the life characteristics are also improved by the surfactant characteristic peculiar to silicon oil.
아래에, 한정하지는 않지만 실시예에 의하여 본 발명을 설명한다.The present invention will be described below by way of examples, without limitation.

[전해액의 조성][The composition of electrolyte solution]
종래의 전해액 :Conventional electrolyte solution:
에틸렌글리콜 : 88.0중량%, 물 : 2.7 중량%, 안식향상 암모늄 : 9.3 중량%,Ethylene glycol: 88.0 wt%, Water: 2.7 wt%, Benzoic ammonium: 9.3 wt%,
Rs=320ΩcmRs = 320Ωcm
Vs=330VVs = 330V
본 발명의 전해액 :Electrolyte Solution of the Invention:
에틸렌글리콜 : 87.0 중량%, 물 : 2.6 중량%, 안식향상 암모늄 : 8.7 중량%, 실리콘유(실시예 1과 동일) : 1.7 중량%Ethylene glycol: 87.0 wt%, Water: 2.6 wt%, Benzoic ammonium: 8.7 wt%, Silicone oil (same as in Example 1): 1.7 wt%
상기한 실시예의 결과에서 판명되듯이, 본 발명에 의하면 중고전압하에 있어서 종래의 전해액에 비하여 누설전류(LC)치를 낮게 억제함과 아울러 신틸레이션을 저감시키고, 또한 내구성의 안정성도 향상된다.As can be seen from the results of the above-described embodiments, the present invention suppresses the leakage current (LC) value lower than the conventional electrolyte solution under high voltage, reduces scintillation, and improves stability of durability.
더우기, 이들의 효과에 덧붙여, 실리콘오일은 전해액에 일반적으로 사용되는 용매에 비하여 인화점이 높으므로(실리콘오일 200℃전후, 에틸렌글리콜 116℃, 글리세린 177℃), 콘덴서의 쇼트 등에 의한 발화사고의 발생을 저감시켜, 안정성을 향상시킨다는 이점도 있다.Furthermore, in addition to these effects, silicon oil has a higher flash point compared to solvents generally used for electrolytes (before and after 200 ° C of silicon oil, 116 ° C of ethylene glycol, 177 ° C of glycerin), and therefore, a fire of an accident due to a short circuit of a capacitor, etc. There is also an advantage of reducing the pressure and improving the stability.
