[발명의 명칭][Name of invention]
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 순수(H2O)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 순수(H2O)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 pure water (H 2 O) added, but the saturated aliphatic of the method of increasing the amount of the first solute. Adipic acid (dipic acid) or ammonium adipate (dimonic acid) has a low solubility in ethylene glycol and pure water (H 2 O), so as not to dissolve more than 12 to 16%, it is difficult to increase the conductivity of the electrolyte.
또한, 순수(H2O)의 배합량을 증대시키는 두번째 방법은 순수(H2O)의 배합량이 일정량 이상 증가되면 고온사용시 전해 콘덴서의 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 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 주체로 하는 용매에 순수(H2O)를 12~18% 첨가하여 혼합하고, 상기 혼합용매에 숙신산(Succinic acid) 또는 그 암모늄염을 2~6%, 아디핀산(adipic acid) 또는 그 암모늄을 8~12% 용해시켜 구성하는 것을 특징으로 하는 알루미늄 전해 콘덴서용 전해액을 제공하여 준다.The present invention for achieving the above object is added by mixing 12-18% pure water (H 2 O) to the solvent mainly ethylene glycol (ethylenglycol), and mixed with the succinic acid (Succinic acid) or its ammonium salt to the mixed solvent It provides an electrolytic solution for an aluminum electrolytic capacitor, characterized by dissolving 2 to 6%, adipic acid or ammonium 8 to 12%.
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 순수(H2O)로 구성되는 혼합용매에 숙신산(succinic acid) 또는 그 암모늄염, 아디핀산(adipic acid) 또는 그 암모늄염을 일정량씩 용해시켜 전해액을 조성한다.The electrolyte solution of the present invention dissolves a certain amount of succinic acid or its ammonium salt, adipic acid or its ammonium salt in a mixed solvent composed of ethylene glycol (ethylenglycol) and pure water (H 2 O) to form an electrolyte solution. .
본 발명에서 전해질로 사용되는 숙신산(succinic acid)은 아디핀산(adipic acid)에 비하여 분자량이 작고 용매인 에틸렌 글리콜(ethyenglycol)에 대한 용해성이 뛰어나서 아디핀산(adipic acid) 또는 그 염을 단독으로 사용시보다 전해질의 양을 증대시킬 수가 있어 전해액의 전도도를 대폭 향상시키는 것이 가능하다.Succinic acid used as an electrolyte in the present invention has a lower molecular weight and superior solubility in ethylene glycol (ethyenglycol) as adipic acid than adipic acid. Since the amount of the electrolyte can be increased, it is possible to significantly improve the conductivity of the electrolyte.
전해질양은 무게비로 숙신산(succinic acid)이 2~6%, 아디핀산(adipic acid)이 8~12%씩 각각 혼합하여 용해시킴이 바람직하며, 전해질의 총량이 20% 이상이 되면 저온에서 결정이 석출되어 전해액으로 사용하는 것이 불가능하다.The amount of electrolyte is preferably dissolved by mixing 2-6% of succinic acid and 8-12% of adipic acid in weight ratio, and when the total amount of electrolyte is 20% or more, crystals are precipitated at low temperature. It is impossible to use it as an electrolyte solution.
종래의 구성에 따른 전해액 및 본 발명의 구성에 따른 전해액에 대한 조성 및 그 특성을 아래 [표 1]에 나타내면 다음과 같다.Composition and characteristics of the electrolyte according to the conventional configuration and the electrolyte according to the configuration of the present invention are shown in Table 1 below.
본 발명의 전해액을 종래의 전해액과 조성 및 전해액 특성을 비교하여 보면 본 발명에 의한 전해액의 특성은 예1, 예2, 예3에 나타나듯이 종래의 전해액에 비하여 전도도값이 크게 상승하여 저손실의 특성이 요구되는 제품에 적용가능하게 되었다.When comparing the composition of the present invention with the conventional electrolyte and the composition and the characteristics of the electrolyte, the characteristics of the electrolyte according to the present invention are as shown in Examples 1, 2, and 3, the conductivity value is significantly increased compared to the conventional electrolyte solution, the characteristics of low loss Applicable to this required product.
그러므로 본 발명의 알루미늄 전해 콘덴서용 전해액은 전도도를 향상시켜 전해 콘덴서의 제품의 손실값(tan δ)을 일정수준 이하로 낮추어 제품의 특성을 향상시키는 효과를 갖는다.Therefore, the electrolytic solution for the aluminum electrolytic capacitor of the present invention has an effect of improving the conductivity of the product by lowering the loss value (tan δ) of the product of the electrolytic capacitor to a certain level or less.
