Description
Technical field
The invention belongs to electrolytic capacitor paper fields, and in particular to a kind of low tightness exempt to be carbonized solid electrolytic capacitor paper and
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 monomer, while being contained in cellulose
There is a large amount of hydroxyl, side reaction can be generated in conductive high polymer monomer polymerization, influence the performance of capacitor；In addition, general electricity
Fiber combination is more close in solution paper, and conductive high polymer monomer is difficult to be adsorbed in electrolytic paper completely, leads to conducting polymer list
It is unevenly distributed in electrolytic paper after body polymerization, also will affect 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
In order to solve the above technical problems, it is an object of the present invention to provide a kind of pair of monomers to have preferably absorption
Property, side reaction is less, while the electrolytic capacitor paper of carbonization treatment is not necessarily in capacitor production process, and of the invention other one
A purpose is to provide the preparation method of above-mentioned electrolytic capacitor paper.
In order to realize above-mentioned first purpose, the invention adopts the following technical scheme:
A kind of low tightness exempts from the solid electrolytic capacitor paper that is carbonized, and the raw material of the electrolytic capacitor paper is by jute pulp and chemical fibre group
At；Jute pulp includes in sisal hemp pulp, manila pulp, jute slurry, Chinese jute pulp, flax pulp, wild goose latex, pineapple leaves slurry and wingceltis latex
One or more, the beating degree of jute pulp are 10 ~ 30 ° of SR, and weight in wet base is 10 ~ 40g；The chemical fibre includes polyester fiber, gathers
One or more of nylon, polyolefine fiber, vinylon fibre and polyacrylonitrile fibre, the length of chemical fibre is 1.5 ~
15mm, fiber number are 0.1 ~ 3dtex；By dry weight percentages, jute pulp is 10 ~ 80%, and chemical fibre is 20 ~ 90%.
Preferably, pressing dry weight percentages, jute pulp is 40 ~ 60%, and chemical fibre is 40 ~ 60%.
Preferably, the beating degree of jute pulp is 10 ~ 20 ° of SR, weight in wet base is 10 ~ 35g.
Preferably, the length of chemical fibre is 2 ~ 10mm, fiber number is 0.2 ~ 2dtex.
In order to realize above-mentioned second purpose, the invention adopts the following technical scheme:
A method of it preparing the low tightness and exempts from the solid electrolytic capacitor paper that is carbonized, this method includes the following steps:
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, obtains low tightness and exempt to be carbonized
Solid electrolytic capacitor paper.
Further, forming is manufactured paper with pulp using cylinder in step 4), and Top wire former concentration is 0.01 ~ 0.5%.
The present invention is by adopting the above-described technical solution, chemical fibre has conductive high polymer monomer in above-mentioned component
Preferable adsorptivity, therefore addition chemical fibre can improve paper to the adsorptivity of conductive high polymer monomer in paper, make
Monomer is evenly distributed in paper；And since binding force is weaker between pure chemistry fiber, it is difficult to it is manufactured paper with pulp by wet-formed,
Therefore a certain amount of plant fiber is needed to assign 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.
