Background technology
Usual motor, which rises, employs -10 DEG C or -25 DEG C of operating temperature of alminium electrolytic condenser requirement or more, since modern humans live
The extension of dynamic range, the movable footprint of the extremely frigid zones mankind is more and more frequent, to drive related electromechanical equipment high and cold
Application under the conditions of area, low pressure, ultra-low temperature surroundings, and the product of usually standard limits the application under relevant environmental conditions,
Therefore it develops a motor applied under the conditions of the low pressure ultra-low temperature surroundings of high temperature area that adapts to and starts aluminium electrolutic capacitor
As certainty.
It replaces ethylene glycol to make main solvent with NN-2 methylformamide (DMF), capacitor is enable effectively to be opened up to operating temperature
- 40 DEG C are opened up, because the solidification point of DMF is -61 DEG C, however DMF is a kind of very strong solvent of corrosivity, can be corroded most of
Structural material, especially as the sealing material rubber of electrolytic capacitor, therefore prolonged use can be to electrolytic capacitor
Leakproofness is destroyed, this is unacceptable for aluminium electrolutic capacitor, while the leakage of DMF can cause brokenly environment
It is bad.
Invention content
The object of the present invention is to provide a kind of ultralow temperature motors to start aluminum electrolytic capacitor electrolyte and its configuration method, solution
Electrolyte of the certainly existing DMF as main solvent, it is existing because DMF is a kind of very strong solvent of corrosivity, it can corrode mostly
Several structural materials, especially as the sealing material rubber of electrolytic capacitor, therefore prolonged use can be to electrolytic capacitor
The leakproofness of device is destroyed, this is unacceptable for aluminium electrolutic capacitor, while the leakage of DMF can cause environment
The problem of destruction.
The technical solution adopted by the present invention to solve the technical problems is：A kind of ultralow temperature motor starting aluminium electrolutic capacitor
Electrolyte includes following component by weight percentage：Ethylene glycol 38~72%, tetrahydrofurfuryl alcohol 8~56%, water 0~10.5%, ten
Two bisgallic acids 4~8.6%, triethylamine 2~6.3%, ethanedioic acid ammonium 1~5.2%, disappear hydrogen agent 0.8~0.5%.
A kind of ultralow temperature motor starts the configuration method of aluminum electrolytic capacitor electrolyte, includes the following steps：
Step (1) is put into after mixing dodecandioic acid, triethylamine according to the ratio in the second reaction kettle, is sufficiently stirred rear, lid
The kettle cover of upper second reaction kettle is kept for 3~4 hours；
Ethylene glycol, tetrahydrofurfuryl alcohol and water are first put into the first reaction kettle by step (2) according to the ratio, after being sufficiently mixed stirring
It is heated to 80~85 DEG C；Then the ethanedioic acid ammonium that mixture and corresponding proportioning are obtained by step (1) is thrown to first together
In reaction kettle, stops heating after 120 DEG C ± 2 DEG C are heated to after being sufficiently stirred, obtain electrolyte；
Step (3) after step (2) the electrolyte natural cooling at least 8 hours, will sample progress electrical parameters detection.
Further, step (1) heating equipment is heat-conducting oil heating tank, and the first reaction is provided in heat-conducting oil heating tank
Kettle, the conduction oil in heat-conducting oil heating tank and reaction kettle lateral wall contact heating reaction kettle, ethylene glycol, tetrahydrofurfuryl alcohol and water are by matching
Than being put into the first reaction kettle, it is sufficiently mixed after stirring again by heat-conducting oil heating to 80-85 DEG C.
Beneficial effects of the present invention：By the different hydrogen bonding actions of the chemical constitution of different solvents, analysis has developed
Mixing (compound) solvent of enough solubility can be provided at -40 DEG C or less for solute；Ethylene glycol-water-tetrahydrofurfuryl alcohol double solvents,
The solidification point of double solvents can reach -60 DEG C hereinafter, this electrolyte is dissolved in by the ammonium salt of double carboxylic acids containing branch by ethylene glycol, water
It is formulated with tetrahydrofurfuryl alcohol composition mixed solvent, can effectively solve the problem that electrolyte of the existing DMF as main solvent, it is existing
Because DMF is a kind of very strong solvent of corrosivity, most of structural material can be corroded, especially as the close of electrolytic capacitor
Closure material rubber, therefore prolonged use can destroy the leakproofness of electrolytic capacitor, this carrys out aluminium electrolutic capacitor
Say it is unacceptable, while the problem of the leakage of DMF can damage environment.
Below with reference to drawings and examples, the present invention is described in detail.
