Abstract

The invention relates to an ultrahigh-voltage flame-retardant electrolyte which comprises the following components in parts by weight: 65-75 parts of ethylene glycol, 5-10 parts of diethylene glycol,1-3 parts of nanoscale silicon dioxide, 2-3 parts of ammonium dodecanedioate, 3-5 parts of ammonium isosebacate, 3-8 parts of ammonium pentaborate, 3-5 parts of PVA-1179, 1-2 parts of o-nitroanisole and and 0.15-0.20 part of tributyl hypophosphite. The preparation method comprises the following steps: (1) firstly, mixing the ethylene glycol, the diethylene glycol, the ammonium pentaborate, the ammonium isodecanedioate and the PVA-1179, heating to 60-75 DEG C, keeping the temperature for 25 minutes and continuously stirring; (2) adding the ammonium dodecanedioate, heating to 145 DEG C, keepingthe temperature for 10 minutes, cooling to 70 DEG C, and keeping the temperature for 210 minutes; and (3) finally adding nanoscale silicon dioxide, uniformly stirring until the solution is transparent, preserving heat for 60 minutes, naturally cooling to 75 DEG C, adding o-nitroanisole and tributyl hypophosphite, and naturally cooling to normal temperature to obtain the electrolyte. The electrolyte is resistant to high temperature and high pressure, the amount of hydrogen generated in the working process of the electrolytic capacitor can be reduced, the electrolyte vapor pressure is reduced, and the flame-retardant effect is good.
