Capacitor electrolytic blending liquid and preparation method thereof

Abstract

The invention discloses a capacitor electrolytic blending liquid and a preparation method thereof. The capacitor electrolytic blending liquid comprises the following components in parts by weight: 35-50 parts of ethylene glycol, 1-2 parts of o-nitroanisole, 10-20 parts of a long-carbon-chain hydroxyl mixture, 10-20 parts of polyvinyl alcohol and a composition of a high-temperature-resistant material of the polyvinyl alcohol, 2-6 parts of ammonium sebacate, 0.5-0.8 part of ammonium hypophosphite and 10-20 parts of 1,2-ethylenediol. The capacitor electrolysis blending liquid can be used for blending electrolyte scrapped due to the performance of the electrolyte, so that the electrolyte can be reutilized, and the cost is reduced. In an electrolyte blended by the capacitance electrolysis blending liquid, the performance is tested by a conductivity tester, a PH tester, a sparking voltage tester, a silver nitrate titration method for detecting the content of chloride ions and the like, and the following parameters are obtained by testing at 30 DEG C: the sparking voltage, the conductivity, the PH value and the content of chloride ions are all normal, and the electrolyte is not abnormal after silver nitrate titration; and the requirement of electrolyte performance blending can be met.

Description

technical field [0001] The invention belongs to the field of electrolytic solution for electrolytic capacitors, and relates to a capacitor electrolytic reconciliation solution and a preparation method thereof. Background technique [0002] The capacitor manufacturer's electrolyte has been recycled for a long time, and the performance parameters of the electrolyte cannot meet the electrical performance requirements. Usually, the electrolyte is released for scrap treatment, which adds additional costs to the factory. [0003] Since the working electrolyte of aluminum electrolytic capacitors works under the premise of long-term recycling, but through the action of vacuum and negative pressure during the production process, the relevant material components in the electrolyte will be lost. Foil ash, paper scraps and other impurities will cause secondary pollution of the electrolyte and indirectly bring hidden dangers to product quality and safety. The application of the present i...

[0003] Since the working electrolyte of aluminum electrolytic capacitors works under the premise of long-term recycling, but through the action of vacuum and negative pressure during the production process, the relevant material components in the electrolyte will be lost. Foil ash, paper scraps and other impurities will cause secondary pollution of the electrolyte and indirectly bring hidden dangers to product quality and safety. The application of the present invention is to reconcile the electrolyte for secondary use
