Abstract
The invention relates to a working electrolyte for an aluminum electrolytic capacitor which is used for an energy-saving lamp, and a preparation method thereof. The working electrolyte comprises a main solvent glycol, a secondary solvent propanetriol, solute 1, 7-ammonium and ammonium pentaborate, and additives blockpolyether and p-nitrophenol. Glycol, 1, 7-ammonium, ammonium pentaborate, blockpolyether and p-nitrophenol are prepared according to the weight percentages of (80%-86%): (12%-16%): (1.5%-2.5%): (0.5%-1.5%). The steps of the preparation are as follows: glycol or the mixed liquid of glycol and propanetriol is heated to 120-125 DEG C; the mixed liquid is cooled down; 1, 7-ammonium and ammonium pentaborate are added into the cool mixed liquid and then stirred to dissolve; and then blockpolyether and p-nitrophenol dissolve after being added, and are stirred at a holding temperature. The electrolyte of the invention has low specific resistance, and the aluminum electrolytic capacitor made of the electrolyte has the advantages that the range of the working temperature is wide, the subzero temperature is negative 40 DEG C, and the service life can last for 5,000 h at positive 125 DEG C, thereby meeting the working requirements of the energy-saving lamp.
