Technical field
The present invention relates to a kind of electrolyte of aluminium electrolutic capacitor, more particularly to a kind of 650V high-pressure aluminum electrolytic capacitors work
Make electrolyte and preparation method thereof.
Background technology
Aluminium electrolutic capacitor is one of base components of electronic product, with the continuous improvement of Quality of electronic products, to aluminium
The performances such as the operating voltage of electrolytic capacitor, service life, upper limit working temperature it is also proposed higher and higher requirement.At present,
Many famous brand name capacitor producers such as the Japan taken its place in the front ranks of the world have released one after another rated operational voltage higher than 650V's
Product, also, the new product family released by they is all in terms of super-pressure mostly, it is seen then that ultra-high voltage aluminum electrochemical capacitor
Device is a kind of trend of future development.Although the market share that the aluminium electrolutic capacitor of China accounts for the world is increasing, super
Still air switch area is there is on high-pressure aluminum electrolytic capacitor, and world's advanced technology also has a certain distance.
Electrolyte is the actual negative electrode of aluminium electrolutic capacitor, plays a part of to provide oxonium ion, repairs anode oxide film, because
This, high performance electrolyte plays vital effect for the quality for ensureing aluminium electrolutic capacitor.At present, for super-pressure
（More than 650V）The exploitation of electrolyte, main preferential ammonium carboxylate salt or carboxylic acid from Long carbon chain, but research and development length used at present
, essentially from foreign countries, domestic production technology is simultaneously immature, therefore can cause the production of electrolyte for carbon chain carboxylic acids' ammonium salt or carboxylic acid
High cost, and the inapplicable production with reality.Additionally, the ammonium carboxylate salt or carboxylic acid of Long carbon chain are due to its carbon chain length, its solubility
It is relatively low, the electrical conductivity of electrolyte can be caused relatively low.Patent CN103811183A provides a kind of aluminium electrolutic capacitor of 630V；Patent
CN103794369A provides a kind of aluminium electrolutic capacitor of 700V；Patent CN104465100A provides a kind of 800V alminium electrolytic condensers
Device, but, they adopt solute based on Long carbon chain ammonium carboxylate salt or carboxylic acid, and its electrolytic conductivity is than relatively low, product damage
Consumption is larger.
The content of the invention

In the present invention, main solvent is good to the dissolubility of solute, and viscosity is low, and dielectric constant is big, it is easy to improve the electricity of electrolyte
Conductance.In the present invention, secondary solvent primarily serves the oxidation efficiency of the viscosity and electrolyte that improve electrolyte so that electrolyte
Viscosity the oxidation efficiency of electrolyte is accelerated, be capable of a certain degree of flash over voltage for improving electrolyte.This
In invention, the secondary solvent for being added can reduce main solvent intermolecular force, improve electrolysis fluid viscosity so as to play
Effect；Secondary solvent has preferable electrocatalysis characteristic simultaneously, can produce Electro Sorb in the breakdown point of anode oxide film, improve sun
The reaction efficiency of pole paper tinsel surface aluminum oxidation, so that oxidation efficiency is accelerated.
In the present invention, solute is short chain solute, due to its solubility property than long-chain solute more preferably, the short carbon of such homogenous quantities
Chain solute its NH4+Ion concentration can be higher than Long carbon chain, so can keep higher in the case where higher flash over voltage is ensured
Electrical conductivity, simultaneously as its carbochain is short, molecular weight is little, electrolysis fluid viscosity also can accordingly diminish.
Flash over voltage elevator can be preferentially adsorbed on anode due to borate or negatively charged former its of boric acid polyester ion
The surface of paper tinsel；As the reaction of formation of polyester can produce water, aggregated good polyester is added in the electrolytic solution, because reaction is flat
The presence of weighing apparatus, therefore the generation of water can be suppressed, can further improve flash over voltage.
Above-mentioned 650V range high voltage aluminum electrolysis capacitor working electrolytes and preparation method thereof, it is preferred that the high jewelling electricity of 650V
Other additives of electrolysis condenser Working electrolyte also including 0.1%-2%, described other additives are phosphoric acid, ortho phosphorous acid
Two or more in ammonium, ammonium hypophosphite, paranitrobenzoic acid, p nitrobenzyl alcohol, paranitrobenzoic acid ammonium.
A kind of preparation method for such as weighing above-mentioned 650V range high voltage aluminum electrolysis capacitor working electrolytes, comprises the following steps：
1) main solvent and secondary solvent are well mixed；
2）It is the solute that 30%-40% is added under conditions of 40-70 degree Celsius in temperature, stirs and to be warming up to 120-13- Celsius
Degree；
3）130-150 degree Celsius of addition flash over voltage elevator is warmed up to, and continues to heat up until flash over voltage elevator
Dissolving；
4）After flash over voltage dissolving completely, 125-135 degree Celsius is cooled to, adds remaining solute, and be incubated 60-90 point
Clock；
5）It is cooled to 100-105 degree Celsius and adds other additives.
In the present invention, flash over voltage elevator needs higher solution temperature, solute promote flash over voltage elevator
Dissolving, but too high temperature can make solute decompose and moisture evaporation, therefore, in order to ensure electrolyte have it is higher
Electrical conductivity, takes the method that solute is added at twice, that is, be initially charged part solute, then adds flash over voltage elevator, then
Remaining solute is added.
Compared with prior art, it is an advantage of the current invention that：1st, viscosity is low, the 650V high-pressure aluminum electrolytic capacitors of the present invention
Selected by Working electrolyte, solvent viscosity is low, and solute carbochain is short, molecular weight is little and solutes content account for electrolysis liquid hold-up proportion it is little,
The viscosity of electrolyte can be made to diminish.2nd, electrical conductivity is high, short carbon chain solute its NH of homogenous quantities in the present invention4+Ion concentration can be than long
The want height, the addition of secondary solvent of carbochain has substantially no effect on the electrical conductivity of electrolyte, can so allow electrolyte to ensure high scintillation electricity
Higher electrical conductivity is kept in the case of pressure.
