Abstract

This invention relates to aluminum electrolytic capacitor and its preparation method, especially relates to aluminum electrolytic capacitor used in flashing light and its preparation method. Its work electrolyte components is that main solvent is ethylene glycol. Secondary solvent is one or mixture N.N dimethyl formamide, N-methyl-2- pyrrolidone, polyethylene glycol octyl phellyl ether and water. The main solute is one or mixture of ammonium benzoate, ammonium sebacate, ammonium pentaborate, azelaic acid hydrogen ammonium, dodecandioic acid ammonium, mannitol. The additive is one of mixture of m-dinitrobenzene, ammonium dibasic phosphate, nitrodracylic acid ammonium and amphi nitryl benzoic alcohol. The capacitor in this invention is good in pressure resistance, the leakage current is little, the slow leakage rally can be used to make flashing light aluminum electrolytic capacitor of rated voltage keep around 330V.

Description

technical field [0001] The invention relates to an aluminum electrolytic capacitor and a preparation method thereof, in particular to an aluminum electrolytic capacitor used for a flash lamp and a preparation method thereof. Background technique [0002] Capacitors are the most widely used and irreplaceable electronic components, and their output accounts for about 40% of electronic components. Electrolytic capacitors are one of the fastest growing components in my country in the past 10 years. At present, the annual production of electrolytic capacitors in China is The volume is close to 25 billion, with an average annual growth rate of 28%, accounting for 1 / 3 of the global output of electrolytic capacitors. In the process of development, aluminum electrolytic capacitors account for three major types of capacitors (electrolytic capacitors, ceramic capacitors, organic film capacitors) output 36.8%. Aluminum electrolytic capacitors are made of corroded and oxidized anode alumi...
