Abstract

The electrolysis for preventing the rising of the inner gas pressure of the capacitor dissolves the ethylene glycol as the main solvent, and the adipic acid, boric acid or its salt as the main solute. The methyl nitro benzoic acid having the good cleaning power and H2 gas absorbing power is also added into the mixture.

Description

알루미늄 전해콘덴서용 전해액Electrolytic Solution for Aluminum Electrolytic Capacitors

본 발명은 알루미늄 전해콘덴서용 전해액에 관한 것이다.The present invention relates to an electrolytic solution for aluminum electrolytic capacitors.

종래의 알루미늄 전해콘덴서의 전해액은 주용매인 에틸렌 글리콜과 NFM계에 아디핀산(Adipic Acid), 붕산 등의 유기 또는 무기산과 그 염들을 용해시켜 사용하고, 기타 내세정성을 향상시키기 위한 트리에틸아민(Triethylamine)등의 알킬아민류와 전해콘덴서의 장시간 사용시 알루미늄상의 산화피막(Al2O3)과 H2O의 반등에 의한 H2가스 발생에 따른 내압상승을 저하시키기 위한 파라니트로페놀(Para nitro phenol)및 파라니트로 안식향산(Para nitro benzoic acid)등의 니트로 화합물을 사용하였다.The electrolyte solution of a conventional aluminum electrolytic capacitor is used by dissolving an organic or inorganic acid such as adipic acid, boric acid and salts thereof in ethylene glycol and NFM system as main solvents, and triethylamine for improving washing resistance. Paranitro phenol to reduce the pressure resistance increase due to H 2 gas generation by the reactivity of Al 2 O 3 and H 2 O on alkylamines such as triethylamine and electrolytic capacitors for a long time And nitro compounds such as paranitro benzoic acid.

그러나 상기의 기능성 약품들을 사용하면 PH 상승과 특히 중고압용 전해액의 내전압을 저하시켜 콘덴서의 사용전압을 한정시킨다.However, the use of the above functional chemicals limits the voltage of the capacitor by lowering the pH and lowering the withstand voltage of the electrolyte for medium and high pressure.

본 발명의 목적은 상기의 단점을 제거하기 위하여 용매와 용질로 구성된 전해액에 내세전성 및 H2가스 흡착 능력을 갖는 메틸-니트로 안식향산(methyl-nitro benezoic acid)을 첨가하여 제조된 전해액을 제공하여 전해액 조성 후 전해액의 특성을 저하시키지 않고자 하는 것이다.An object of the present invention is to provide an electrolyte solution prepared by adding methyl-nitro benezoic acid having a pre-precision resistance and H 2 gas adsorption capacity to the electrolyte solution consisting of a solvent and a solute in order to eliminate the above disadvantages It is to not reduce the characteristic of electrolyte solution after composition.

본 발명을 상세히 설명하면 다음과 같다.The present invention is described in detail as follows.

본 발명의 전해액은 주용매로서 에틸렌 글리콜과 주용질로서 아디핀산, 붕산 또는 그 염들을 용해시키고 이것에 내세정성 및 H2가스흡착 능력으 갖는 메틸-니트로 안식향산을 첨가하여 제조된다.The electrolyte solution of the present invention is prepared by dissolving adipic acid, boric acid or salts thereof as the main solvent and ethylene glycol as the main solvent and adding methyl-nitro benzoic acid having washing resistance and H 2 gas adsorption capacity thereto.

본 발명의 전해액을 사용한 알루미늄 전해콘덴서는 세정공정과 전해콘젠서를 인쇄회로기판상에 부착할때 납땜에 의한 불순물제거 공정에서 사용되는 할로겐화 탄화수소가 콘덴서 제품내부에 침투하여 분리된 할로겐이온(예 Cl)에 의한 부식이 메틸니트로 안식향산에 의해 방지가 된다.In the aluminum electrolytic capacitor using the electrolytic solution of the present invention, the halogenated hydrocarbon used in the cleaning process and the impurity removal process by soldering when attaching the electrolytic capacitor to the printed circuit board penetrates into the condenser product, thereby separating halogen ions (eg Cl). Corrosion by is prevented by methylnitrobenzoic acid.

전해액 조성약품중의 H2O 및 콘젠서지에 함유된 H2O와 제조공정산의 흡수된 H2O에 의해 알루미늄 전해콘덴서를 고온에서 장시간 사용하면 Al, Al2O3와 H2O와의 반응에 따라 피막의 열화가 발생하고 H2가스생성으로 내압이 상승되는데 본 발명의 전해액은 니트로 화합물에 의한 H2가스흡착으로 알루미늄 전해콘덴서의 수면특성을 향상시킨다.The reaction of the H 2 O and the manufacturing process when used for a long time at high temperatures, the aluminum electrolytic capacitors by absorbed H 2 O of the settlement Al, Al 2 O 3 and H 2 O contained in the H 2 O and konjen surge in the electrolyte composition of drug As a result, deterioration of the film occurs and the internal pressure is increased due to H 2 gas generation. The electrolyte of the present invention improves the sleep characteristics of the aluminum electrolytic capacitor by H 2 gas adsorption by the nitro compound.

상기와 같이 메틸니트로 안식향산을 이용하여 전해약 조성시 전해액의 특성이 저하되지 않고 콘덴서제품의 특성을 저하시키지 않으며 할로겐화 탄화수소에 대한 내세정성 및 H2가스흡착성을 가져서 콘덴서의 내압상승을 억제하고 콘덴서제품의 수면특성이 향상되는 효과가 있다.Using methyl-nitro benzoic acid as the electrolyte but the properties of the drug composition when the electrolyte is not degraded does not degrade the characteristics of the capacitor products inhibit hereafter fixed and H 2 gas adsorption the pressure increase in the condenser gajyeoseo for the halogenated hydrocarbon and the capacitor product Has an effect of improving the sleep characteristics.
