Insulation plate for electrolytic capacitors formed by molding for 40-60 minutes at a temperature of 140 ° C to 160 ° C and a pressure of 60 to 70kg / ㎠ and then cooling for 20 to 30 minutes in an atmosphere of 60 ° C to 70 ° C Suggest.
이와 같이 하여 본 고안은 온도변화에 무관하게 안정된 전기적 절연도와 내압성을 유지하여 절연성이 우수하고, 물성이 안정되는 효과를 제공한다.In this way, the present invention maintains stable electrical insulation and pressure resistance regardless of temperature change, and provides excellent insulation and stable physical properties.
이러한 본 고안을 더욱 상세히 설명하면 다음과 같다.When explaining the present invention in more detail as follows.
본 고안은 먼저 염소 성분이 제거된 페놀을 주성분으로 하는 열경화성 수지를 제조하여야 한다.The present invention must first prepare a thermosetting resin mainly containing phenol from which chlorine is removed.
이를 위하여 이온교환에 의하여 얻어진 정제수를 포름알데히드 97%에 넣고 교반하여 희석함으로써 포름알데히드 37-38%의 용액을 준비한다.For this, a solution of formaldehyde 37-38% is prepared by adding purified water obtained by ion exchange to 97% of formaldehyde and stirring to dilute it.
이어서 포름알데히드 37-38%를 순수한 페놀과1.1몰로 배합한 다음 25%의 암모니아수를 촉매로 유화 반응시켜 탈수시킨다.Subsequently, 37-38% of formaldehyde is combined with 1.1 moles of pure phenol, and 25% of aqueous ammonia is emulsified with a catalyst to dehydrate.
이와 같이 탈수시킨 페놀수지를 98%내지 99%의 에탄올로 희석하여 고형분 55% 내지 60%가 되도록 하면 이때의 점도가 60cps 내지 70cps가 되는 것이며, 이러한 과정으로 염소이온이 제거된 페놀을 주성분으로 하는 열경화성 절연수지가 제조될 수 있는 것이다.When the dehydrated phenolic resin is diluted with 98% to 99% of ethanol so that the solid content is 55% to 60%, the viscosity becomes 60 cps to 70 cps. Thermosetting insulating resin can be produced.
이어서 본 고안에서는 함침지를 준비하여야 한다.Subsequently, impregnated paper should be prepared in the present invention.
이를 위하여 함침조를 사용하여야 하는데 이때 함침조의 내부는 이물질이 전혀 없는 상태로 되도록 세척하고 이러한 함침조에 상기 준비된 염소이온이 제거된 페놀을 주성분으로 하는 열경화성 절연수지를 채운 후 0.2mm 내지 0.25mm 두께의 크라프트지를 롤상태에서 그대로 함침시키면서 크라프트지 롤에 침투한 수지의 함량이 종이무게의 43%내지 45%가 되는 시점까지 수지량을 조정하여 건조로에 투입한다.To this end, an impregnation tank should be used, in which the interior of the impregnation tank is washed so that there are no foreign substances at all, and then filled with a thermosetting insulating resin mainly composed of phenol from which the prepared chlorine ion has been removed. While the kraft paper is impregnated in the roll state, the amount of resin is adjusted to the point at which the content of the resin penetrated into the kraft paper roll becomes 43% to 45% of the paper weight, and then it is put into the drying furnace.
이때의 건조로는 내부온도가 130℃내지 150℃가 되도록 하며, 30m 내지 40m 길이의 건조로를 8-11m/min의 속도로 통과시켜 건조 완료한다.At this time, the drying furnace is such that the internal temperature is 130 ℃ to 150 ℃, passing through a drying furnace of 30m to 40m length at a speed of 8-11m / min to complete the drying.
이와 같이 하여 건조 완료된 후에는 일정 길이와 폭으로 적절히 절단하여 준비한다. 준비된 규격의 함침 크라프트지는 원하는 두께에 따라 적당한 매수씩 스테인레스판을 끼워 가면서 적층한다.After drying in this way, it is prepared by cutting appropriately to a predetermined length and width. The impregnated kraft paper of the prepared standard is laminated by inserting the stainless plate by the appropriate number according to the desired thickness.
이와 같이 하여 적층한 후 가열압착프레스에 넣고 가열, 가압하게 되는데 이때 가열온도는 140℃내지 160℃의 온도로 40분 내지 60분간 60kg/㎠-70kg/㎠의 압력으로 가열, 가압한 다음 60℃ 내지 70℃의 분위기에서 20분 내지 30분 동안 냉각 한 후 소정의 규격과 적절한 형상으로 절단하는 등 가공하여 전해콘덴서용 절연판으로 사용할 수 있게 되는 것이다.After laminating in this way, the mixture is placed in a heat press press and heated and pressurized. At this time, the heating temperature is 60 ° C. to 160 ° C., which is heated and pressurized at a pressure of 60 kg / cm 2 -70 kg / cm 2 for 40 minutes to 60 ° C., followed by 60 ° C. After cooling for 20 to 30 minutes in an atmosphere of 70 to 70 ℃ to be processed into a predetermined size and the appropriate shape, such as to be used as an insulating plate for an electrolytic capacitor.
실제로는 이와 같이 제작된 본 고안에 의한 절연판은 1.0mm의 두께로 제작하는 것이 보편적이며, 이에 알루미늄 단자 고정을 위한 고정공을 뚫어 사용하게 된다.In practice, the insulating plate according to the present invention manufactured as described above is generally manufactured to have a thickness of 1.0 mm, and thus, a fixing hole for fixing an aluminum terminal is used.
이러한 본 고안에 의한 절연판의 제조를 위한 구체적인 실시예를 살펴보면 다음과 같다.Looking at a specific embodiment for the production of the insulating plate according to the present invention as follows.
본 고안은 이온교환에 의하여 얻어진 정제 수를 포름알데히드 97%에 넣고 교반하여 희석함으로써 포름알데히드 37%의 용액을 준비한다.The present invention prepares a solution of formaldehyde 37% by diluting the purified water obtained by ion exchange into 97% formaldehyde and stirring.
이어서 전기의 포름알데히드 37%의 용액과 순수한 페놀과 1.1몰로 배합한 다음 25%의 암모니아수를 촉매로 유화 반응시켜 탈수시킨다.Subsequently, 1.1% of the former formaldehyde solution and pure phenol are combined with 1.1 mol, and 25% aqueous ammonia is emulsified with a catalyst to dehydrate.
이와 같이 탈수시킨 페놀수지를 98%의 에탄올로 희석하여 고형분 55%가 되도록 하면 이때의 점도가 60cps가 되는 것이며, 이러한 과정에서 염소이온이 제거된 주성분이 페놀인 열경화성 절연수지가 제조될 수 있는 것이다.When the dehydrated phenolic resin is diluted with 98% ethanol to a solid content of 55%, the viscosity is 60 cps. In this process, a thermosetting insulating resin in which chlorine ions are the main component phenol is manufactured. .
이러한 절연수지가 채워진 함침조에 크라프트지를 함침시켜 크라프트지 롤에 침투한 수지의 함량이 종이무게의 43%로 되도록 조정하여 건조로에 투입한다.Kraft paper is impregnated into the impregnating tank filled with the insulating resin, and the content of the resin penetrated into the kraft paper roll is adjusted to 43% of the paper weight, and then charged into the drying furnace.
이때 길이가 30m인 건조로는 내부온도가 135℃가 되도록 하며, 이를 10m/min의 속도로 통과시켜 건조 완료한다.At this time, the drying furnace having a length of 30 m is to be an internal temperature of 135 ℃, and complete the drying by passing it at a speed of 10 m / min.
이와 같이 하여 건조 완료된 후에는 두께가 1mm가 되도록 적층한후 각 매마다 스테인레스판을 끼워 가면서 적층한다.After drying in this manner, the laminate is laminated to have a thickness of 1 mm and then laminated while sandwiching a stainless plate for each sheet.
이와 같이 하여 적층한 후 가열압착프레스에 넣고 가열, 가압하게 되는데 이때 가열온도는 150℃의 온도로 50분간 65kg/㎠의 압력으로 가열, 가압한 다음 탈거 하여 가공하면 본 고안에 의한 전해콘덴서용 절연판으로 사용할 수 있게 되는 것이다.After laminating in this way, it is put in a hot pressing press and heated and pressurized. At this time, the heating temperature is 150 ° C. for 50 minutes, pressurized and heated at a pressure of 65 kg / cm 2, and then removed and processed. It can be used as.
이와 같이 하여 얻어진 본 고안에 의한 절연판은 85℃의 온도로 2000시간 가열한 후 표면저항이 10 ×105내지 10 ×1010［㏁］이 되어 매우 우수하며, 경도는 60 내지 70［HS］가 되었고, 인장강도는 75kg/㎠-90kg/㎠이 되어 변형율이 매우 적었으며, 신장율은 470% 내지 610%가 되었고 염소분은 2 내지 3ppm에 불과하여 고용량 전해콘덴서의 절연판으로 요구되는 물성 기준치를 충족시키는 우수한 물성을 나타내었다.The insulating plate according to the present invention obtained as described above was heated at a temperature of 85 ° C. for 2000 hours and the surface resistance became 10 × 10 5 to 10 × 10 10 [㏁], which is very excellent, and the hardness was 60 to 70 [HS]. The tensile strength is 75kg / ㎠-90kg / ㎠, so the strain is very small, the elongation rate is 470% to 610% and the chlorine content is only 2-3ppm, which meets the standard of physical properties required for insulation plates of high capacity electrolytic capacitors. It showed excellent physical properties.
이와 같이 본 고안은 함침수지의 염소성분이 제거된 것이어서 고열을 받더라도 염소이온이 분리되어 전극, 극판으로의 침투로 인한 절연파괴나 부식으로 인한 특성 변화 등이 초래되지 않으므로 전해콘덴서의 안정된 작동 상태를 확보할 수 있게 되는 것이면서도 가공이 용이하고 강도가 충분하여 내압성이 탁월한 전해콘덴서용 절연판을 제공할 수 있게 되는 효과가 있다.In this way, the chlorine component of the impregnated resin is removed, so even when subjected to high heat, chlorine ions are separated and do not cause insulation breakdown or corrosion due to corrosion due to penetration into the electrode or electrode plate. In addition to being able to secure, it is easy to process and has sufficient strength, thereby providing an insulating plate for an electrolytic capacitor having excellent pressure resistance.
