Description
본 발명은 알루미늄 전해콘덴서의 저압용 전해액에 관한 것으로, 더욱 상세하게는 전해액의 전도도를 향상시켜 전해콘덴서 제품의 손실값(tan δ)을 일정수준 이하로 낮추는 알루미늄 전해콘덴서용 전해액에 관한 것이다.The present invention relates to a low pressure electrolytic solution of an aluminum electrolytic capacitor, and more particularly, to an electrolytic solution for an aluminum electrolytic capacitor which improves conductivity of an electrolytic solution and lowers a loss value (tan δ) of an electrolytic capacitor product to a predetermined level or less.
일반적으로 알루미늄 전해콘덴서에 사용되는 저압용 전해콘덴서용 전해액은 에틸렌글리콜(ethylenglycol)을 주용매로 하고, 순수(H2O)를 혼합한 혼합용매에 아디핀산(adipic acid) 또는 그 암모늄염을 용해시켜 구성하였으나 전해액의 전도도가 좋지 못하여 제품의 손실값(tan δ)이 저하되지 못했다.In general, the electrolytic solution for low pressure electrolytic capacitors used in aluminum electrolytic capacitors has ethylene glycol (ethylenglycol) as the main solvent, and adipic acid or its ammonium salt is dissolved in a mixed solvent mixed with pure water (H 2 O). However, since the conductivity of the electrolyte was poor, the loss value (tan δ) of the product did not decrease.
알루미늄 전해콘덴서용 전해액의 전도도를 향상시키기 위해서는 전해질인 용질의 양을 증대시키는 방법과 첨가되는 순수(H2O)의 양을 증대시키는 방법등 2가지의 방법이 있으나 첫번째 방법의 전해질인 용질의 양을 증대시키는 방법에서의 포화지방족 디카르본산인 아디핀산(Adipic acid) 또는 암모늄 아디페이트(Ammonium Adipate)는 에틸렌글리콜(ethylenglycol)과 순수(H2O)에 대한 용해도가 낮아 상승이 어렵다.In order to improve the conductivity of the electrolytic solution for aluminum electrolytic capacitors, there are two methods of increasing the amount of solute as an electrolyte and increasing the amount of pure water (H 2 O) added. Saturated aliphatic dicarboxylic acid adipic acid or ammonium adipate in the method of increasing the solubility in ethylene glycol (ethylenglycol) and pure water (H 2 O) is difficult to rise.
또한, 순수(H2O)의 배합량을 증대시키는 두번째 방법은 순수(H2O)의 배합량이 일정량 이상 증가되면 고온사용시 전해콘덴서의 내압이 상승하고 특성이 저하되는 결점이 있다.In addition, the second method of increasing the amount of the pure water (H 2 O) has the disadvantage that when the amount of the pure water (H 2 O) increases more than a predetermined amount delivered using a high temperature rise, and the breakdown voltage of the capacitor characteristic is degraded.
따라서 본 발명은 전술한 문제점을 해결하기 위해 창출한 것으로, 본 발명의 목적은 전해액의 전도도를 향상시켜 전해콘덴서 제품의 손실값(tan δ)을 일정수준 이하로 낮추어 제품의 특성을 향상시키는 구성을 갖는 알루미늄 전해콘덴서용 전해액을 제공함이다.Therefore, the present invention was created to solve the above problems, an object of the present invention is to improve the conductivity of the electrolyte solution to lower the loss value (tan δ) of the electrolytic capacitor product to a certain level to improve the characteristics of the product It provides an electrolyte solution for aluminum electrolytic capacitors.
전술한 목적을 달성하기 위한 본 발명은 에틸렌글리콜(ethylenglycol)을 주체로 하는 용매에 순수(H2O)를 12-18% 첨가하여 혼합하고, 상기 혼합용매에 포름산(formic acid) 또는 그 암모늄염을 1-4%, 아디핀산(adipic acid) 또는 그 암모늄염을 8-12% 용해시켜 구성하는 것을 특징으로 하는 알루미늄 전해콘덴서용 전해액을 제공하여 준다.The present invention for achieving the above object is added by mixing 12-18% pure water (H 2 O) to a solvent mainly ethylene glycol (ethylenglycol), and formic acid (formic acid) or its ammonium salt to the mixed solvent It provides an electrolytic solution for aluminum electrolytic capacitors, characterized in that 1-4%, adipic acid or its ammonium salt by dissolving 8-12%.
이하에서는 실시예를 통하여 본 발명의 알루미늄 전해콘덴서용 전해액을 상세히 설명하기로 한다.Hereinafter, the electrolyte solution for an aluminum electrolytic capacitor of the present invention will be described in detail through examples.
[실시예]EXAMPLE
본 발명의 전해액은 에틸렌글리콜(etylenglycol)과 순수(H2O)로 구성된 혼합용매에 포름산(formic acid) 또는 그 암모늄염과 아디핀산(adipic acid) 또는 그 암모늄염을 일정량씩 용해시켜 전해액을 조성한다.The electrolyte solution of the present invention forms an electrolyte by dissolving formic acid or its ammonium salt and adipic acid or its ammonium salt in a predetermined amount in a mixed solvent composed of ethylene glycol (etylenglycol) and pure water (H 2 O).
본 발명의 전해질로 사용되는 포름산(formic acid)은 아디핀산(adipic acid)에 비하여 분자량이 작고 용매인 에틸렌글리콜(etylenglycol)에 대한 용해성이 뛰어나서 전해액에 대한 전도도가 향상되나 전해액의 내전압이 충분하지 않은 결점이 있어 전해질로 단독사용이 불가능하였다.Formic acid used as an electrolyte of the present invention has a lower molecular weight and superior solubility in ethylene glycol (etylenglycol) than adipic acid, so that the conductivity of the electrolyte is improved, but the withstand voltage of the electrolyte is not sufficient. There was a flaw and it was impossible to use alone as an electrolyte.
본 발명의 전해질 양의 조성은 각각 포름산(formic acid) 1-4%, 아디핀산(adipic acid) 8-12%씩 혼합하여 용해하는 것이 양호하며, 포름산(formic acid)이 4% 이상 증가하면 전해액의 전도도는 향상되나 내전압이 충분하지 못하여 전해콘덴서의 적용할 수 있는 전압 범위가 낮아진다.The composition of the electrolyte amount of the present invention is preferably dissolved by mixing 1-4% of formic acid and 8-12% of adipic acid, respectively, and increasing the amount of formic acid by 4% or more. The conductivity of is improved, but the withstand voltage is not enough, so the applicable voltage range of the electrolytic capacitor is lowered.
종래 전해액 및 본 발명의 전해액 구성과 그 특성을 아래 [표 1]에 나타낸다.The conventional electrolyte solution, the electrolyte solution structure of this invention, and its characteristic are shown in the following [Table 1].
본 발명의 전해액을 종래의 전해액과 비교하여 보면 종래의 전해액에 비하여 전도도값이 크게 상승하여 저손실의 특성이 요구되는 제품에 적용 가능하게 되었다.When comparing the electrolyte solution of the present invention with the conventional electrolyte solution, the conductivity value is significantly increased as compared with the conventional electrolyte solution, so that it can be applied to products requiring low loss characteristics.
종래 및 본 발명의 전해액을 이용하여 6.3Volt-100μF의 전해콘덴서 제품을 제조하여 그 특성을 아래 [표 2]에 나타낸다.The electrolytic capacitor product of 6.3Volt-100μF was manufactured using the electrolytic solution of the prior art and this invention, and the characteristic is shown in the following [Table 2].
상기의 결과는 시료수 20개의 평균치이다.The above result is an average value of 20 samples.
본 발명의 전해액을 사용하여 종래의 전해액에 비교하면 제품의 초기특성이 향상되었으며, 특히 초기 특성의 손실(tan δ) 특성이 크게 향상되어서 고신뢰성의 전해콘덴서를 생산하는 효과가 있다.Compared with the conventional electrolyte solution using the electrolyte solution of the present invention, the initial characteristics of the product is improved, in particular, the loss of the initial characteristics (tan δ) characteristics are greatly improved, thereby producing a highly reliable electrolytic capacitor.
