Description
본 발명은 알루미늄 전해콘덴서 고압용 전해액에 관한 것이다.The present invention relates to an aluminum electrolytic capacitor high pressure electrolyte.
본 발명은 충분한 내전압을 가지면서 전해액의 전도도가 향상되어 하이리플(HIGH RIPPLE)용 소형화 제품에 적용가능하며 고온에서 특성이 안정하고 사용온도 범위가 확대됨은 물론 장시간 사용 가능하도록 한 것이다.The present invention is to improve the conductivity of the electrolyte while having a sufficient withstand voltage, and can be applied to miniaturized products for HIGH RIPPLE, it is stable at high temperatures, extended use temperature range, as well as long-term use.
알루미늄 전해콘덴서 중고압용 전해액은 일반적으로 에틸렌글리콜을 주체로한 용매에 붕산계 전해질을 용해시켜 사용하거나 에틸렌글리콜을 주체로한 용매에 아제라인산, 세바틴산 등과 같은 이염기성의 유기산 또는 상기산의 암모늄염을 용해시켜 사용하였다.A high pressure electrolytic solution for aluminum electrolytic capacitors is generally used by dissolving a boric acid-based electrolyte in a solvent mainly composed of ethylene glycol or a dibasic organic acid such as azeline acid, sebacic acid, or an ammonium salt of the acid in a solvent mainly composed of ethylene glycol. It was used by dissolving.
상기 붕산계 전해액은 에스테르화 반응에 의해 다량의 수분이 생성되고 전극박의 열화를 촉진 TANδ 등 특성의 악화와 100℃ 이상의 전해콘덴서에는 수분이 증발되어 콘덴서의 내압을 상승시켜 케이스 방폭변이 작동되어 파양이 되는 결점이 있다.The boric acid-based electrolyte generates a large amount of water by the esterification reaction, promotes deterioration of the electrode foil, deteriorates characteristics such as TANδ, and evaporates moisture to the electrolytic capacitor at 100 ° C. or higher, thereby increasing the internal pressure of the condenser to operate the case. There is a drawback to this.
또한 이염기성산 등의 전해액은 필요한 내전압이 충분치 않고 전해액의 전도 도가 좋지 않아 저손실, LOW ESR용 전해액으로 사용이 어렵고 또한 사용온도범위가 작은 결점이 있다.In addition, electrolytes such as dibasic acids have the disadvantages that the required withstand voltage is not sufficient and the conductivity of the electrolyte is poor, making it difficult to use as a low loss, low ESR electrolyte, and having a small operating temperature range.
이와같은 문제점을 해결하기 위해 디에틸렌글리콜과 같은 다강라콜을 혼합용매로 사용하기도 하나 내전압은 다소 향상이 되나 500WV급 이상의 콘덴서에 적용하기에는 내전압이 충분하지 못하는 결점이 있다.In order to solve this problem, multi-galacol such as diethylene glycol may be used as a mixed solvent, but the breakdown voltage may be slightly improved, but the breakdown voltage may not be sufficient to be applied to a capacitor of 500 WV or more.
본 발명은 충분한 내전압을 가지면서 전해액의 전도도가 향상되어 하이리플(HIGH RIPPLE)용 소형화 제품에 적용가능하며 고온에서 특성이 안정하고 사용온도 범위가 확대됨은 물론 장시간 사용 가능한 알루미늄 전해콘덴서 초고압용 전해액을 제공하는데 목적을 두고 있다.The present invention has a sufficient withstand voltage and improves the conductivity of the electrolyte, so that it can be applied to miniaturized products for high ripple, stable at high temperatures, extended use temperature range, as well as ultra-high pressure electrolyte for aluminum electrolytic capacitors that can be used for a long time. The purpose is to provide.
이를 위해 본 발명은 알루미늄 전해콘덴서 초고압용 전해액에 있어서, 용매인 에틸렌글리콜41중량%에 암모늄1.6옥탄디카르복실레이트12중량%를 첨가하고 콜로이달실리카에틸렌글리콜용액15중량%을 첨가하며 붕산암모늄3중량%, 벤질알콜25중량%, 파라니트로벤질알콜1중량%, 폴리비닐알콜3중량%를 혼합하여 구성되는 것을 특징으로 하는 알루미늄 전해콘덴서 초고압용 전해액을 제공하고자 한다. To this end, the present invention is an aluminum electrolytic capacitor ultra-high pressure electrolyte, ammonium borate 3 is added to 41% by weight of ethylene glycol 12% by weight of ammonium 1.6 octane dicarboxylate and 15% by weight of colloidal silica ethylene glycol solution and ammonium borate 3 It is to provide an aluminum electrolytic capacitor ultra-high pressure electrolytic solution, characterized in that by mixing by weight, benzyl alcohol 25% by weight, paranitrobenzyl alcohol 1% by weight, polyvinyl alcohol 3% by weight.

본 발명은 에틸렌글리콜용매에 LONG CHAIN의 측쇄 이염기성산 또는 그 암모늄염과 직쇄의 이염기성산염을 혼합, 전해질로 사용하여 전해액의 전도도와 열적 안정성을 향상시켰다.The present invention improves the conductivity and thermal stability of the electrolyte solution by mixing a side chain dibasic acid of LONG CHAIN or its ammonium salt with a straight chain dibasic acid salt in an ethylene glycol solvent as an electrolyte.
또한 전해액의 내전압을 상승시키기 위해 콜로이달실리카(COLLOIDAI SILLICA)의 에틸렌 글리콜 분산 용액과 폴리비닐알콜을 첨가하였으며 콘덴서의 수명특성을 향상시키기 위해 니트로 화합물 중 파라니트로벤질알콜을 추가하여 전해액을 완성시켰다.In addition, polyvinyl alcohol and ethylene glycol dispersion solution of colloidal silica (COLLOIDAI SILLICA) were added to increase the withstand voltage of the electrolyte, and paranitrobenzyl alcohol in the nitro compound was added to complete the electrolyte.
본 발명은 콜로이달실리카의 에틸렌글리콜 용액의 용해도를 개선하기 위해 보조용매로 벤질알콜을 사용하며 또한 내전압을 개선하기 위해 붕산암모늄을 보조 전해질로 첨가하여 전해액을 완성하였다.In the present invention, benzyl alcohol is used as a cosolvent to improve solubility of ethylene glycol solution of colloidal silica, and ammonium borate is added as an auxiliary electrolyte to improve the breakdown voltage, thereby completing an electrolyte solution.
