Technical field
The present invention relates to the technology of preparing of aluminium electrolutic capacitor, and in particular to a kind of preparation side of Non-carbonized solid capacitor
Method.
Background technology
In the prior art, solid-state aluminum capacitor more using conducting polymer as electrolyte, and takeup type solid-state aluminum capacitor
Structure and takeup type liquid aluminum capacitor identical structure.What it is different from liquid is that to adhere on the electrolytic paper of solid capacitor is to lead
Electric macromolecule, and what is adsorbed on liquid electric capacity electrolytic paper is electrolyte.For liquid electric capacity, electrolytic paper is the load of electrolyte
Body, electrolyte absorption on electrolytic paper after ion in electrolyte still can be with free shuttling by being electrolysed ply of paper, therefore will not shadow
Ring the work of liquid electric capacity.And although the electrolytic paper in solid capacitor also serves as the carrier of solid state electrolysis paper, but due to traditional electrolyte
Paper is usually the two-layer composite design used, and one layer is then liquid-adsorption layer, and another layer is then ion barrier, it is however generally that is inhaled
Liquid layer is loose porous layer, and ion barrier is then compacted zone；Why solid capacitor sub-prime will be carbonized, mainly for
Compacted zone in electrolytic paper is carbonized into loose porous layer.The compactness structure and nonconducting property of its side can cause solid
While state electrolyte is difficult to enter in capacitor, also results in solid electrolyte electric conductivity and be greatly reduced, so that solid-state
Electric capacity unit for electrical property parameters deteriorates.
In order to avoid a series of problems caused by electrolytic paper property, solved at present using sub-prime carbonization technique.Sub-prime passes through
After crossing high temperature cabonization, electrolytic paper can be carbonized, and on the one hand cause electrolytic paper to become loose porous, on the other hand the electrolytic paper of carbonization
Itself there is certain electric conductivity, can thus solve the adverse effect that electrolytic paper is brought to solid capacitor.But this carbonizer
Although skill can effectively solve the adverse effect that electrolytic paper is brought, a series of problem is also brought along simultaneously, is cost first
Increase, carbonization need the temperature at 250 DEG C~270 DEG C or so to carry out prolonged carbonization treatment to sub-prime, and this needs personnel, set
Many-sided cost input such as standby, electric power.In addition, the structure of carbonization meeting heavy damage cathode and anode paper tinsel, especially to anode foils, meeting
So that the oxide-film in anode foils produces many defects, the performance that this results in product is extremely unstable, and especially leakage current is easy
It is exceeded.In addition, high-temperature operation environment can cause workshop condition severe, the increase of operator operation intensity, and personnel rate is high.

1~3h is dried under the conditions of DEG C.
4) ethanol is immersed：Dried core bag will be melted into immerse in monomer ethanol solution, be impregnated with normal temperature and pressure conditionses
2min。
5) it is impregnated with oxidant：To be impregnated with the core bag after monomer immerse the solvent that concentration is 30%~70% be methanol or
In the p-methyl benzenesulfonic acid ferrous solution of ethanol, 1~3min is impregnated with the case where air pressure is 80~120Pa vacuum condition.
7) it polymerize：Core bag after impregnation oxidant is put into baking oven and polymerize；
8) group is vertical：Core bag after polymerization is sealed in the aluminum hull with rubber stopper；
9) aging：Product is at a temperature of 115~135 DEG C, under operating voltage, aging 110 minutes.
In the step 5 of the present invention, the oxidizing agent solution is preferably the p-methyl benzenesulfonic acid ferrous solution that solvent is methanol, its
