Description
Technical field
The invention belongs to electrolytic capacitor paper fields, and in particular to one kind exempts from be carbonized solid electrolytic capacitor paper and its preparation
Method.
Background technique
Electrolyte in solid electrolytic capacitor is solid-state conductive high molecular material, the structure packet of solid electrolytic capacitor
Include anode, cathode, electrolytic paper and solid-state conductive high molecular material.Electrolytic capacitor paper be prepare electrolytic capacitor can not or
One of scarce raw material is mainly used for adsorbing conductive high polymer monomer and oxidant in the capacitor, forms polymer, play simultaneously
The effect of pole plate is isolated, prevents anode and cathode from directly contacting and short-circuit.
Traditional electrolytic capacitor paper is holocellulos material, weaker to the adsorption capacity of conductive high polymer monomer, simultaneously
Contain a large amount of hydroxyl in cellulose, side reaction can be generated in conductive high polymer monomer polymerization, influence the performance of capacitor；This
Outside, fiber combination is more close in general electrolytic paper, and conductive high polymer monomer is difficult to be adsorbed in electrolytic paper completely, leads to conduction
It is unevenly distributed in electrolytic paper after high molecular polymerization, influences capacitor performance.Currently, the solid electrolyte capacitor produced in the market
Device needs in production process to carry out carbonization treatment to electrolytic paper at 250 ~ 270 DEG C, to improve the sponginess of electrolytic paper and to list
The adsorptivity of body.It under this technique, needs for entire capacitor to be heated under higher temperature, production technology is complicated, and pyrocarbon
Change process will cause destruction to the structure of cathode and anode foil, cause properties of product unstable, leakage current is easy exceeded；Further, since
Heating temperature is high, needs to consume a large amount of energy, adds somewhat to the production cost of enterprise.
Therefore, in order to simplify the production technology of solid electrolytic capacitor, production energy consumption is reduced, developing one kind, to exempt from carbonization solid
State electrolytic capacitor paper, this kraft capacitor paper have preferable adsorptivity to conductive high polymer monomer, and can reduce conductive height
Side reaction when molecule monomer polymerize, while without carrying out carbonization treatment to kraft capacitor paper in capacitor production process.
Summary of the invention
It is an object of the present invention to provide a kind of pair of monomers to have preferable adsorptivity, and side reaction is less, raw in capacitor
The electrolytic capacitor paper of carbonization treatment is not necessarily to during producing, another object of the present invention is to provide above-mentioned electrolytic capacitor paper
Preparation method.
In order to realize above-mentioned first purpose, the invention adopts the following technical scheme:
One kind exempting from the solid electrolytic capacitor paper that is carbonized, and the raw material of the electrolytic capacitor paper is made of wood pulp and chemical fibre；It is described
Wood pulp include non-bleaching needle-point leaf pulp, bleaching needle-point leaf pulp, non-bleached hardwood pulp, bleached hardwood pulp, one in straw pulp
Kind is several, and the beating degree of wood pulp is 5 ~ 25 ° of SR, and weight in wet base is 10 ~ 30g；The chemical fibre includes polyester fiber, polyamide
One or more of fiber, polyolefine fiber, vinylon fibre and polyacrylonitrile fibre, the length of chemical fibre is 1.5 ~
15mm, fiber number are 0.1 ~ 3dtex；By dry mass percentages, wood pulp is 10 ~ 80%, and chemical fibre is 20 ~ 90%.
Preferably, pressing dry mass percentages, wood pulp is 40 ~ 60%, and chemical fibre is 40 ~ 60%.
Preferably, the beating degree of wood pulp is 10 ~ 20 ° of SR, weight in wet base is 15 ~ 25g.
Preferably, the length of chemical fibre is 3 ~ 10mm, fiber number is 0.2 ~ 1.5dtex.
In order to realize above-mentioned second purpose, the invention adopts the following technical scheme:
A method of exempting from the solid electrolytic capacitor paper that is carbonized described in preparing, which is characterized in that this method includes step below
It is rapid:
1) dispersion is discongested after jute pulp being added water, obtains slurry A；
2) chemical fibre is uniformly dispersed, obtains slurry B；
3) slurry A and slurry B is sufficiently mixed, and obtains mixed slurry；
4) mixed slurry is subjected to online drainage and formation, using squeezing, drying, batches and cut, obtain exempting from carbonization solid-state electricity
Electrolytic capacitor paper.
Preferably, forming is manufactured paper with pulp using cylinder in step 4), Top wire former concentration is 0.01 ~ 0.5%.
The present invention is by adopting the above-described technical solution, chemical fibre has preferable absorption to monomer in above-mentioned component
Property, therefore addition chemical fibre can improve paper to the adsorptivity of monomer in paper, and monomer is made to be evenly distributed in paper；
And since binding force is weaker between pure chemistry fiber, it is difficult to be manufactured paper with pulp by wet-formed, it is therefore desirable to a certain amount of plant
Fiber assigns the paper certain intensity, can smoothly manufacture paper with pulp.
Solid electrolytic capacitor paper of exempting to be carbonized of the invention has good adsorptivity to monomer, and it is poly- to can be reduced monomer
The generation of side reaction during conjunction, while paper has lower tightness, and monomer is uniformly distributed in paper.Cause
This, without carrying out carbonization treatment to kraft capacitor paper in the production process of capacitor.
