摘　　要：为了延长开关电源用高压铝电解电容器的使用寿命,通过开发并使用硼酸系改性添加剂和24,30碳支链二元酸铵盐,合理选取电解液的溶剂、溶质和吸氢剂开发宽温高电导率的电解液。优选H110-530VF低比容阳极箔、F3K-3.0VF化成负极箔、WS285-60电解纸,100%树脂丁基橡胶等原材料,以及对含浸工艺、钉花工艺、组装封口等关键工艺改进,研制出105℃高温负荷寿命达10 000 h的开关电源用高压铝电解电容器。In order to extend the life of the high voltage aluminum electrolytic capacitor used in switch power supplies, based on the high voltage capacitors feature, the boric acid modified additives and 24, 30 carbon branched-chain dibasic ammonium salt and solvent, solute, hydrogen absorber used for working elecrtolyte were studied and chosen. To optimize the H110-530VF low specific capacity anode foil, the F3K-3.0VF negative foil and WS285-60 electrolytic paper and 100% resin butyl rubber raw materials, the impregnation, riveting technology and assembled sealing were improved as well, the aluminum electrolytic capacitors used in switch power supplies were developed. This product can endure 10 000 h load life at 105 ℃.
