Abstract

The invention discloses an electrolyte, and a preparation method and application thereof. The electrolyte comprises the following parts by weight: 60-70 parts of glycol, 10-25 parts of butyl octanedioic acid ammonium, 1-2 parts of mannitol, 5-8 parts of polyethylene glycol 2000, 3-5 parts of boric acid, 3-5 parts of ammonium dodecanedioate, 2-5 parts of ammonium Hydrogen azelate, 0.5-1 part of ammonium hypophosphite, 2 parts of ammonium adipate and 0.5-2 parts of hydrogen elimination agent. According to the invention, the calorific value of a capacitor product can be reduced when a switching power supply works for a long time, and product performance is guaranteed; meanwhile the voltage endurance capability of the electrolyte is improved, thereby greatly prolonging the service life of the capacitor product, and guaranteeing that the switch power supply can be used for a long time.

Description

technical field [0001] The invention belongs to the field of electrolytic solution for electrolytic capacitors, and relates to an electrolytic solution and a preparation method thereof. Background technique [0002] Electrolyte is the core component of aluminum electrolytic capacitors, and its performance directly affects the performance and life of capacitor products. [0003] In the application field of switching power supplies, the requirements for electronic components of electrolytic capacitors are relatively high, and the leakage of capacitors will increase during aging; after long-term work, the equivalent series resistance of capacitors increases, the impedance increases, and the capacitors generate heat. Shortening, to a certain extent, will affect the normal and safe operation of the switching power supply. Electrolyte is the core component of aluminum electrolytic capacitors, and its high-voltage resistance, low impedance, and long-life coefficient performance ha...
