Description
본 발명은 알루미늄 전해콘덴서용 전해액에 관한 것으로, 특히 충분한 내전압을 가지게 되어 하이리플용 전해콘덴서의 소형화가 가능하고, 고온에서의 특성이 안정되어 사용온도 범위가 확대되며, 장시간 사용가능하도록 된 알루미늄 전해콘덴서용 전해액에 관한 것이다.The present invention relates to an electrolytic solution for aluminum electrolytic capacitors, in particular, has a sufficient withstand voltage, which makes it possible to miniaturize an electrolytic capacitor for high ripple, stable at high temperatures, and thus widen the use temperature range, and is capable of using for a long time. It relates to an electrolytic solution for capacitors.
일반적으로 알루미늄 전해콘덴서는 전극으로 알루미늄 박판을 사용하고, 전해질로서 암모늄에 염류와 쌍극성 유기용매에 용해된 유기산으로 구성되어 있는 액체 전해질을 사용하여 단위면적당 정전용량이 높아 부품의 소형, 고용량화에 적합한 콘덴서이다.In general, aluminum electrolytic capacitors use aluminum thin plates as electrodes, and liquid electrolytes composed of salts in ammonium and organic acids dissolved in bipolar organic solvents as electrolytes, and have high capacitance per unit area. It is a capacitor.
이러한 알루미늄 전해콘덴서의 전해액으로 에틸렌글리콜, 글리세린, 붕산, 암모니아수등으로 된 페이스트를 사용하여 대용량콘덴서에 주로 사용되고 있으나, 주파수특성이나 온도특성이 나쁘고 누설전류, 유전체손실이 클 뿐 아니라, 정격전압을 초과하는 고압을 인가하게 되면 안전밸브가 찢어져서 가스화된 전해액이 외부로 분출되는 등 문제점이 있어 주로 저주파 전력회로등을 중심으로 사용되어 왔다.It is mainly used for large capacity capacitors using paste made of ethylene glycol, glycerin, boric acid, ammonia water, etc. as the electrolyte solution of aluminum electrolytic capacitors, but it has bad frequency characteristics, temperature characteristics, high leakage current, dielectric loss, and exceeds rated voltage. When the high pressure is applied, the safety valve is torn off and the gasified electrolyte is ejected to the outside, which has been mainly used for low frequency power circuits.
그리고, 종래에 주로 사용되는 알루미늄 전해 콘덴서용 전해액으로, 에틸렌글리콜 용매에 용질로서 붕산 또는 붕산암모늄을 용해시킨 전해액이 있으나, 이 전해액은 장시간 사용하게 되면 에스테르화 반응이 일어나며 이에 따라 다량의 수분이 발생하게 되어 고온중에서 증기압이 높아지게 되는 문제점이 있다.In addition, conventionally used electrolyte solution for aluminum electrolytic capacitors, there is an electrolyte solution in which boric acid or ammonium borate is dissolved as a solute in an ethylene glycol solvent, but this electrolyte solution causes esterification reaction when a long time is used, and thus a large amount of water is generated. There is a problem that the vapor pressure is increased at high temperatures.
또한 상기한 문제점을 해결하기 위해 에틸렌 글리콜 용매에 아제라인산 또는 세바틴산의 암모늄염을 용해시켜 사용하기도 하나, 이러한 전해액은 용매에 대한 용질의 용해도가 낮아 전도도를 향상시키기 어려운 문제점이 있다.In addition, in order to solve the above problems, one may be used by dissolving the ammonium salt of azaline acid or sebatinic acid in an ethylene glycol solvent, such an electrolyte has a problem that it is difficult to improve the conductivity because the solubility of the solvent in the solvent is low.
이에 본 발명은 상기한 제문제점을 해결하기 위한 것으로, 충분한 내전압을 가지게 되어 하이리플용 전해콘덴서의 소형화가 가능하고, 고온에서의 특성이 안정되어 사용온도범위가 확대되며, 장시간 사용가능하도록 된 알루미늄 전해콘덴서용 전해액을 제공하는데 그 목적이 있다.Accordingly, the present invention is to solve the above problems, it has a sufficient withstand voltage and can be miniaturized electrolytic capacitors for high-ripple, stable at high temperature characteristics, the use temperature range is extended, the aluminum to be used for a long time Its purpose is to provide an electrolytic solution for an electrolytic capacitor.
