Description
본 발명은 알루미늄 전해 콘덴서의 저압용 전해액에 관한 것으로, 더욱 상세하게는 전해액의 전도도를 향상시켜 전해 콘덴서 제품의 손실값(tan δ)을 일정수준 이하로 낮추는 알루미늄 전해 콘덴서용 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 the conductivity of the electrolytic solution and lowers the loss value (tan δ) of the electrolytic capacitor product to a predetermined level or less.
종래의 알루미늄 전해 콘덴서에 사용되는 저압용 전해 콘덴서용 전해액은 에틸렌 글리콜(Ethylenglycol )을 주용매로 하고, 물(H2O)을 혼합한 혼합용매에 아디핀산(adipic acid) 또는 그 암모늄염을 용해시켜 구성하였으나 전해액의 전도도가 좋지 못하여 제품의 손실값(tan δ)이 저하되지 못했다.The electrolytic solution for low pressure electrolytic capacitors used in conventional aluminum electrolytic capacitors is made of ethylene glycol (Ethylenglycol) as a main solvent, and adipic acid or its ammonium salt is dissolved in a mixed solvent containing water (H 2 O). However, since the conductivity of the electrolyte was poor, the loss value (tan δ) of the product did not decrease.
전해액의 전도도를 향상시키기 위해서는 전해질인 용질의 양을 증대시키는 방법과 첨가되는 물(순수)의 양을 증대시키는 방법등 2가지의 방법이 있으나 첫번째의 용질의 양을 증대시키는 방법의 포화지방족 디카르본산인 아디핀산(Adipic acid) 또는 암모늄 아디페이트(Ammonium Adipate)는 에틸렌 글리콜과 물(순수)에 대한 용해도가 낮아 12~16% 이상 용해되지 않고, 전해액의 전도도 상승이 어렵다.There are two ways to improve the conductivity of the electrolyte solution: the method of increasing the amount of solute as an electrolyte and the method of increasing the amount of water (pure water) added, but the saturated aliphatic dicar of the method of increasing the amount of the first solute. Adipic acid (Adipic acid) or ammonium adipate (Ammonium Adipate) is a low solubility in ethylene glycol and water (pure water) is not dissolved more than 12-16%, it is difficult to increase the conductivity of the electrolyte.
또한, 물(순수)의 배합량을 증대시키는 두번째 방법은 물의 배합량이 일정량 이상 증가되면 고온사용시 전해 콘덴서의 내압이 상승하고 특성이 저하되는 결점이 있다.In addition, the second method of increasing the blending amount of water (pure water) has a drawback that when the blending amount of water is increased by a certain amount or more, the internal pressure of the electrolytic capacitor is increased and the characteristics are deteriorated during high temperature use.
따라서 본 발명은 전술한 문제점을 해결하기 위해 창출한 것으로 본 발명의 목적은 전해액의 전도도를 향상시켜 전해 콘덴서 제품의 손실값(tan δ)을 일정수준 이하로 낮추어 제품의 특성을 향상시키는 구성을 갖는 알루미늄 전해 콘덴서용 전해액을 제공함이다.Therefore, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to improve the conductivity of the electrolytic solution, thereby lowering the loss value (tan δ) of the electrolytic capacitor product to a predetermined level or less to improve the characteristics of the product. It provides an electrolytic solution for an aluminum electrolytic capacitor.
전술한 목적을 달성하기 위한 본 발명은 에틸렌 글리콜(ethylenglycol)을 주체로하는 용매에 순수(H2O)를 15~20% 첨가하여 혼합하고, 상기 혼합용매에 숙신산(Succinic acid) 또는 그 암모늄염을 12~22% 용해시켜 구성하는 것을 특징으로 하는 알루미늄 전해 콘덴서용 전해액을 제공하여 준다.In order to achieve the above object, the present invention adds 15-20% pure water (H 2 O) to a solvent mainly composed of ethylene glycol (ethylenglycol), and mixes the succinic acid or its ammonium salt to the mixed solvent. It provides an electrolytic solution for aluminum electrolytic capacitors, characterized in that 12 to 22% by dissolving.
이하에서는 실시예를 통하여 본 발명의 알루미늄 전해 콘덴서용 전해액을 상세히 설명하기로 한다.Hereinafter, the electrolyte solution for an aluminum electrolytic capacitor of the present invention will be described in detail with reference to Examples.
[실시예]EXAMPLE
본 발명의 전해액은 에틸렌 글리콜(ethylenglycol)과 물로 구성되는 혼합용매에 숙신산(succinic acid) 또는 그 암모늄염을 용해시켜 구성하는데, 전술한 에틸렌 글리콜(ethylenglycol )의 용매에는 15~20%의 순수(H2O)를 첨가하며, 또한 전술한 혼합용매에 숙신산(succinic acid) 또는 그 암모늄염을 12~22% 용해시켜 구성한다.Electrolyte solution of the present invention is composed by dissolving succinic acid or its ammonium salt in a mixed solvent consisting of ethylene glycol (ethylenglycol) and water, in the solvent of the aforementioned ethylene glycol (ethylenglycol) of 15 to 20% pure water (H 2 O) is added, and 12-22% of succinic acid or its ammonium salt is dissolved in the above-described mixed solvent.
본 발명에서 전해질로 사용되는 숙신산(succinic acid)은 아디핀산(adipic acid)에 비하여 분자량이 작고 용매인 에틸렌 글리콜(ethylenglycol)에 대한 용해성이 뛰어나서 용매에 대해 중량비로 16~22%까지 용해 가능하며 전해액의 전도도 상승에 크게 기여한다.Succinic acid used as an electrolyte in the present invention has a lower molecular weight and superior solubility in ethylene glycol (ethylenglycol) as adipic acid, and thus can be dissolved in a weight ratio of 16 to 22% by weight with respect to the solvent. Contributes significantly to the increase in conductivity.

종래 및 본 발명의 전해액을 이용하여 16Volt-1000μF의 전해 콘덴서 제품을 제조하여 그 특성을 [표 2]에 나타낸다.The electrolytic capacitor product of 16 Volt-1000 micro F was manufactured using the electrolyte solution of the conventional and this invention, and the characteristic is shown in [Table 2].
고온 부하 시험은 85℃에서 500시간 동안 16V의 정격 전압을 인가하여 얻은 결과이며 상기의 결과는 시료수 20개의 평균치이다.The high temperature load test was obtained by applying a rated voltage of 16V at 85 ° C. for 500 hours, and the result is an average of 20 samples.
본 발명의 전해액을 사용하면 종래의 전해액에 비교하여 제품의 초기 특성 및 고온부하 시험 특성이 모두 향상되었으며 특히 제품의 초기 특성의 손실값(tan δ) 및 고온 특성의 손실값(tan δ)특성이 크게 향상되어서 고신뢰성의 전해 콘덴서를 생산하는 효과가 있다.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, the loss value (tan δ) and the loss value (tan δ) of the high temperature characteristics of the product are improved.
