preparation example Construction

[0039] The preparation process of additives is also very critical. After in-depth research on the additive formula ratio and preparation process, the preparation method of the flash voltage booster of the present invention is obtained, including:

[0040] Stirring and mixing the alcohol solvent and the inorganic acid, heating to the first temperature range and keeping it warm for the first time;

[0041] Continue to add organic acids, polyols and macromolecular substances, stir and mix, and keep warm for a second period of time;

[0042] Warming the solution that meets the requirements of the second time length for heat preservation to the second temperature range, after heat preservation for the third time length, cooling to the third temperature range, and heat preservation for the fourth time length, the minimum value of the second temperature range is greater than the first temperature range a maximum temperature range;

[0043] Cool down to the operating temperature rang...

Abstract

The invention discloses a sparking voltage boosting agent, a preparation method thereof and an electrolyte. The preparation method of the sparking voltage boosting agent comprises the following steps: mixing an alcohol solvent with an inorganic acid, heating to a first temperature range, and keeping the temperature for a first duration; continuously adding the organic acid, the polyhydric alcohol and the macromolecular substance, mixing, and continuously keeping the temperature for a second time length; the solution with heat preservation meeting the second time length requirement is heated to a second temperature range, after heat preservation is conducted for a third time length, the solution is cooled to the third temperature range, heat preservation is conducted for a fourth time length, and the minimum value of the second temperature range is larger than the maximum value of the first temperature range; and the temperature is reduced to the use temperature range, the sparking voltage boosting agent is formed, and continuous stirring is needed in the processes. According to the invention, the pressure resistance of the electrolyte can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of electrolytes for high-voltage electrolytic capacitors, in particular to a flash voltage booster and a preparation method thereof. Background technique [0002] Aluminum electrolytic capacitors are one of the most critical and important electronic components in electronic circuits. The development of aluminum electrolytic capacitors mainly has the following directions: 1) to ultra-high voltage, the voltage has rapidly developed from the previous highest voltage of 450V to 500V, 550V, 600V, etc., and even higher in recent years; 2) to wide temperature Development, from the original -25~+85℃, to -40~+105℃, and now there is a trend to develop to -55~+125℃ or even +150℃; 3) To develop in the direction of high frequency, low resistance and long life, etc. . The development direction of aluminum electrolytic capacitors is actually the result of various materials or technological progress that make up aluminum ...
