Description
본 발명은 알루미늄 전해콘덴서의 고압용 전해액에 관한 것으로, 특히 충분한 내전압을 가지면서 전해액의 전도도값이 향상되어 하이리플(High Ripple)용, 소형화 제품의 제작이 가능함, 고온에서 특성이 안정되어 사용온도 범위가 확대되고 장시간 사용가능한 전해콘덴서용 전해액에 관한 것이다.The present invention relates to an electrolytic solution for high pressure of an aluminum electrolytic capacitor, and in particular, having a sufficient withstand voltage, the conductivity value of the electrolytic solution is improved, and thus high ripple and miniaturized products can be manufactured. The present invention relates to an electrolytic capacitor electrolyte which is extended in scope and can be used for a long time.
종래 고압용 콘덴서에 사용된 전해액은 에틸렌 글리콜을 주체로 한 용매에 아제라인산(Azelaic acid), 세바틴산(Sebacic acid)등과 같은 고급의 직쇄 이염기성산 같은 유기산과 붕산(Boric acid)등과 같은 무기산 또는 상기 산들의 암모늄 염을 용질로써 용해시켜 사용하였다.Conventional electrolytes used in high-pressure condensers are organic solvents such as boric acid and organic acids such as high-quality straight-chain dibasic acids such as azelaic acid and sebacic acid in solvents mainly composed of ethylene glycol. The ammonium salt of the acids was used as a solute.
그러나 전술한 전해액은 기존 에틸렌 글리콜 용매에 직쇄이염기성산을 용해 사용한 전해액보다 전도성은 증진되나 전해액의 내전압이 낮아져서 400V 이상의 제품에는 적용을 못하고 400V이하의 전해콘덴서에만 적용하는 문제점이 있다.However, the above-mentioned electrolyte solution is more conductive than the electrolyte solution using a linear dibasic acid dissolved in a conventional ethylene glycol solvent, but the withstand voltage of the electrolyte is lowered, so that it is not applicable to products of 400V or more, and has a problem of applying only to an electrolytic capacitor of 400V or less.
따라서 본 발명은 전술한 문제점을 해결하기 위해 창출한 것이다.Therefore, the present invention was created to solve the above problems.
본 발명의 목적은 전술한 바와 같은 문제를 해결하기 위하여 전해액의 내전압을 높여서 400V이상의 전해콘덴서에 적용할 수 있는 조성비율을 갖는 알루미늄 전해콘덴서용 전해액을 제공함이다.An object of the present invention is to provide an electrolytic solution for an aluminum electrolytic capacitor having a composition ratio applicable to an electrolytic capacitor of 400V or more by increasing the withstand voltage of the electrolytic solution in order to solve the above problems.
전술한 목적을 달성하기 위한 본 발명은 엘틸렌 글리콜 60.5~64.5%와 디에틸렌 글리콜 22~26%를 혼합한 혼합용매에 고급의 측쇄이염가성산인 암모늄-2-부틸옥탄 디오에이트(Ammonium-2-Buthyl-octandioate)8~12%와 오붕산 암모늄(Ammonium penta Borate) 1~5%를 혼합하여 용질로 사용하고 파라니트로 벤질알콜을 0.5~1% 용해시켜 구성하는 것을 특징으로 한다.The present invention for achieving the above object is an ammonium-2-butyloctane dioate (Ammonium-2-) which is a high quality branched chain divalent acid in a mixed solvent of 60.5 to 62.5% of elethylene glycol and 22 to 26% of diethylene glycol. Buthyl-octandioate) 8 to 12% and ammonium pentaborate (Ammonium penta Borate) 1 to 5% of the mixture is used as a solute and characterized in that it is composed by dissolving 0.5 to 1% of paranitrobenzyl alcohol.
이하에서는 실시예를 참조하여 본 발명을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to Examples.
[실시예]EXAMPLE
본 발명의 전해액은 에틸렌 글리콜 60.5~64.5%와 디에틸렌 글리콜 22~26%를 혼합한 혼한 용매에 용질로 고급의 측쇄 이염기성산인 암모늄-2-부틸 옥탄디오에이트(Ammonium-2-Buthyl-octandioate) 8~12% 오붕산 암모늄(Ammonium penta Borate) 1~5%를 일정비율로 혼합하여 용해시키고 파라니트로 벤질알콜을 0.5~1% 첨가하여 전해액을 구성한다.The electrolyte solution of the present invention is a high-quality branched dibasic acid, ammonium-2-butyl octanedioate (Ammonium-2-Buthyl-octandioate) as a solute in a mixed solvent of 60.5 to 65.5% of ethylene glycol and 22 to 26% of diethylene glycol. 1 ~ 5% of 8 ~ 12% ammonium pentaborate is mixed in a certain ratio to dissolve it, and 0.5 ~ 1% of paranitrobenzyl alcohol is added to form an electrolyte solution.
종래 전해액 및 본 발명의 전해액 구성과 그 특성을 아래 표1에 나타낸다.Conventional electrolyte solution and electrolyte composition of the present invention and its properties are shown in Table 1 below.
표1과 같이 본 발명의 전해액은 종래의 전해액과 비교하여 전도도가 상승되고, 내전압 특성이 상승되어 450V의 고전압 전해콘덴서에 적용하여 고신뢰성을 증대시키는 것이 가능하다.As shown in Table 1, the electrolytic solution of the present invention has higher conductivity and higher withstand voltage characteristics compared to the conventional electrolytic solution, and can be applied to a high voltage electrolytic capacitor of 450V to increase high reliability.
종래 및 본 발명의 전해액을 이용하여 450V-100uF의 전해콘덴서 제품을 제조하여 그 특성을 표2에 표시한다.The electrolytic capacitor product of 450V-100uF is manufactured using the electrolytic solution of the prior art and this invention, and the characteristic is shown in Table 2.
고온부하 시험은 450V의 정격전압을 인가하여 얻은 결과이고 상기의 결과는 시료수 10개의 평균치이며, 종래에는 750시간 경과후 5개 시료의 펑크(punk) 불량발생으로 특성체크를 못하였다.The high temperature load test was a result obtained by applying a rated voltage of 450 V. The above result was an average value of 10 samples, and conventionally, the characteristics were not checked due to the puncture failure of five samples after 750 hours.
본 발명의 전해액을 사용하면 종래의 전해액에 비교하여 제품의 초기특성 및 고온부하 시험특성이 모두 향상되었으며 특히 제품의 손실(tanδ)의 변화가 적어 안정된 특성을 갖는 전해 콘덴서를 제조하는 것이 가능하다.When the electrolyte solution of the present invention is used, both the initial characteristics and the high temperature load test characteristics of the product are improved as compared with the conventional electrolyte solution, and in particular, it is possible to manufacture an electrolytic capacitor having stable characteristics due to a small change in product loss (tanδ).
