Problems solved by technology

[0004] The working environment temperature of the electrolyte of aluminum electrolytic capacitors is high, and high temperature resistance is required. At the same time, some filter aluminum electrolytic capacitors are required to withstand the high-frequency oscillation of the latter stage, and the actual work is in the state of high frequency and high ripple current. Therefore, in order to make it suitable for a wider range , more reliable work, we need it to have high temperature resistance, high frequency, high ripple and high resistance; but at present, the common electrolyte configuration of medium and high voltage aluminum electrolytic capacitors in my country is: boric acid + PVA + ethylene glycol + solute low-cost system, Its life is short, high temperature resistance is poor, ripple resistance is low

Abstract

The invention belongs to the technical field of electrolytes, and particularly relates to a multifunctional boric-acid-free electrolyte and a preparation method thereof. The multifunctional boric-acid-free electrolyte is characterized by comprising the following components: ethylene glycol, diethylene glycol, an organic high-molecular polymer, ammonium pentaborate, mannitol, ammonium sebacate, ammonium dodecanedioate, organic long-carbon-chain ammonium carboxylate with a branched chain, an oxygen inhibitor, a hydrogen elimination agent and pure water. The preparation method comprises the following steps: S1, heating the ethylene glycol and the diethylene glycol to 135 DEG C, and then adding the organic high-molecular polymer to completely dissolve the ethylene glycol and the diethylene glycol; s2, after the organic high-molecular polymer is completely dissolved, cooling to 130 DEG C, then adding ammonium pentaborate, mannitol, ammonium sebacate, ammonium dodecanedioate and organic long-carbon-chain ammonium carboxylate with a branched chain, and keeping the temperature for 1 hour at 120 DEG C; s3, preserving heat for 1 hour, cooling to 85 DEG C, adding an oxygen inhibitor, a hydrogen eliminating agent and pure water, and uniformly stirring; and S4, uniformly stirring, and cooling to normal temperature.

Description

technical field [0001] The invention belongs to the technical field of electrolyte, and in particular relates to a multifunctional boric acid-free electrolyte and a preparation method. Background technique [0002] As capacitors are widely used and irreplaceable electronic components. Its output accounts for about 40% of the total electronic components, while aluminum electrolytic capacitors account for about 36.8% of the output of the three major types of capacitors. [0003] At present, my country has become the main producer of aluminum electrolytic capacitors in the world. In 2004, the output of China's aluminum electrolytic capacitors reached 70 billion, accounting for 40% of similar products in the world, with sales exceeding 10 billion yuan. With the rapid development of PC products, TV sets, DVD and other audio-visual products, household appliances such as washing machines, energy-saving lamps, transformers, and automotive electronics, the market demand for aluminu...
