Description
본 발명은 알루미늄 전해 콘덴서의 고압용 전해액에 관한 것으로, 특히 충분한 내전압을 가지면서 전해액의 전도도값이 향상되어 하이리플용(High Ripple) 소형화 제품의 제작이 가능하며, 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, has a sufficient withstand voltage and improves the conductivity value of the electrolytic solution, thereby making it possible to manufacture a miniaturized product for high ripple, and having stable characteristics at high temperature. 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 주체로한 용매에 아제라인산(Azelaic acid), 세바틴산(Sebacic acid) 등과 같은 고급의 직쇄이염 기성산 또는 상기산의 암모늄염을 용질로써 용해시켜 사용하였다. 그러나 상기와 같이 전해액을 구성하면 에틸렌 글리콜에 대한 이염기성산 및 그 염들의 용해도가 작아 100℃이상의 고온에서 장시간 전해액을 제조해야 하는 결점과 전해콘덴서로 제작후 고온하에서 장시간 사용할 때 에틸렌 글리콜 용매와 이염기성산의 용질과의 사이에 에스테르화 반응이 진행된다.The electrolytic solution used in the conventional high pressure condenser was used by dissolving a high-quality straight-chain dibasic acid such as azelaic acid, sebacic acid, or ammonium salt of the acid as a solute in a solvent mainly composed of ethylene glycol. . However, when the electrolyte is composed as described above, the solubility of dibasic acid and salts thereof in ethylene glycol is small, and the defect of preparing electrolyte solution for a long time at a high temperature of 100 ° C. or higher, and the ethylene glycol solvent and dichloride when used for a long time at high temperature after the production of an electrolytic capacitor. The esterification reaction proceeds with the solute of the acid.
상기 반응에 따라 생성된 물과 전극반 반응으로 콘덴서 제품의 용량감소, tanδ증대의 특성열화 원인이 되고 아울러 콘덴서 내압의 상승으로 케이스의 방폭변이 작동되는 결점이 있다.Water and electrode panel reaction produced by the above reaction causes a decrease in the capacity of the capacitor product, a characteristic deterioration of the tan δ increase, and the explosion-proof side of the case is operated due to an increase in the internal pressure of the capacitor.
따라서 본 발명은 상기의 문제를 해결하기 위하여 창출된 것이다.Therefore, the present invention was created to solve the above problem.
본 발명의 목적은 상기와 같은 문제점을 해결하기 위하여 고급의 직쇄이염기성산 또는 그 염을 에틸렌 글리콜 용매에 용해하는 방법대신에 고급의 측쇄 염기성산 또는 그 염을 용매인 에틸렌 글리콜에 용해시키고 전기 음성도가 큰 니트로 화합물을 첨가하여 콘덴서의 수명을 연장시키는 고신뢰성 전해액을 제공하고자 하는 것이다.It is an object of the present invention to solve the above problems, instead of dissolving a higher linear dibasic acid or a salt thereof in an ethylene glycol solvent, a higher side chain basic acid or a salt thereof is dissolved in a solvent of ethylene glycol and electronegative. It is to provide a highly reliable electrolyte solution by adding a large nitro compound to extend the life of the capacitor.
본 발명을 실시예를 참조하여 상세히 설명한다.The present invention will be described in detail with reference to Examples.

Dissolve and use. In order to improve the life characteristics of the condenser and to remove and remove hydrogen (H 2 ) gas generated when the condenser is used for a long time, P-nitrobenzyl alcol of nitro compound having a high electronegativity is 0.5 to 2% is added and an electrolyte solution is comprised.

종래 및 발명의 전해액을 이용하여 400V - 47μF의 전해콘덴서 제품을 제조하여 그 특성을 표 2에 표시한다.400V-47μF electrolytic capacitors were prepared using conventional and inventive electrolyte solutions, and their properties are shown in Table 2.
고온부하 시험은 105℃ 1000시간 동안 정격 전압을 인가하여 나온 결과이며 시료수 10개의 평균치이다.The high temperature load test is the result of applying the rated voltage for 1000 hours at 105 ℃ and is an average of 10 samples.
본 발명의 전해액을 사용하면 종래의 전해액에 비해 초기특성 및 고온 부하시험특성이 전부 향상되며 특히 tanδ의 변화가 적어 안정된 특성을 갖는 전해 콘덴서를 제조하는 것이 가능하다.When the electrolyte solution of the present invention is used, the initial characteristics and the high temperature load test characteristics are all improved compared with the conventional electrolyte solution, and in particular, it is possible to manufacture an electrolytic capacitor having stable characteristics due to the small change in tan δ.
