Description
Technical field
The invention belongs to electrolytic capacitor paper fields, and in particular to a kind of enhanced low tightness of coating exempts from the solid state electrolysis that is carbonized
Kraft capacitor paper and preparation method thereof.
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 monomer and oxidant in the capacitor, forms polymer, while playing isolation pole plate
Effect, 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, influences capacitor performance.Currently, the solid electrolytic capacitor produced in the market,
It needs to carry out carbonization treatment to electrolytic paper at 250 ~ 270 DEG C in production process, to improve the sponginess of electrolytic paper and to monomer
Adsorptivity.It under this technique, needs for entire capacitor to be heated under higher temperature, production technology is complicated, and high temperature cabonization
Process will cause destruction to the structure of cathode and anode foil, cause properties of product unstable, leakage current is easy exceeded；Further, since plus
Hot 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, a kind of low tightness is developed and exempts from
Carbonization solid electrolytic capacitor paper (number of patent application: 2018091011182, the applying date: on September 10th, 2018), this capacitor
Device paper has preferable adsorptivity to conductive high polymer monomer, and can reduce side reaction when conductive high polymer monomer polymerization,
It is not necessarily to carry out kraft capacitor paper carbonization treatment in capacitor production process simultaneously, but the intensity of the solid electrolytic capacitor paper
Not enough.
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, the electrolytic capacitor paper of carbonization treatment is not necessarily in capacitor production process, and have good intensity.
Another object of the present invention 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 enhanced low tightness of coating exempts from the solid electrolytic capacitor paper that is carbonized, and the raw material of the electrolytic capacitor paper is by jute pulp and change
Learn fiber composition；Jute pulp includes sisal hemp pulp, manila pulp, jute slurry, Chinese jute pulp, flax pulp, wild goose latex, pineapple leaves slurry and wingceltis
One or more of latex, the beating degree of jute pulp are 10 ~ 30 ° of SR, and weight in wet base is 10 ~ 40g；The chemical fibre includes polyester
One or more of fiber, Fypro, polyolefine fiber, vinylon fibre and polyacrylonitrile fibre, the length of chemical fibre
Degree is 1.5 ~ 15mm, and fiber number is 0.1 ~ 3dtex；By dry weight percentages, jute pulp is 10 ~ 80%, chemical fibre is 20 ~
90%；The surface spray of the electrolytic capacitor paper sprays or dip coated has enhancement layer, and coating weight accounts for paper over dry after coating
The 1 ~ 10% of quality.
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.
Preferably, the ingredient of spraying coating liquid or dip coated liquid is polyvinyl alcohol and its derivative, polyacrylamide
One or more of with starch.
In order to realize above-mentioned second purpose, the invention adopts the following technical scheme:
A method of it preparing the enhanced low tightness of coating and exempts from the solid electrolytic capacitor paper that is carbonized, this method includes following
The step of:
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, spraying coating or dip coated, drying, batched
And cutting, it obtains the enhanced low tightness of coating and exempts from the solid electrolytic capacitor paper that is carbonized.
Further, forming is manufactured paper with pulp using cylinder in step 4), and Top wire former concentration is 0.01 ~ 0.5%.
Further, the coating fluid mass concentration of spraying coating and dip coated is 0.1 ~ 10%.
The present invention is by adopting the above-described technical solution, the enhanced low tightness of coating of the invention exempts from the solid state electrolysis electricity that is carbonized
Container paper has good adsorptivity to monomer, and can be reduced the generation of side reaction during monomer polymerization, while paper has
There is lower tightness, monomer is uniformly distributed in paper.Therefore, without to capacitor in the production process of capacitor
Device paper carries out carbonization treatment.In above-mentioned component chemical fibre to conductive high polymer monomer have preferable adsorptivity, therefore
Chemical fibre is added in paper can improve paper to the adsorptivity of conductive high polymer monomer, be distributed monomer in paper
It is even；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
Fibres assign the paper certain intensity, can smoothly manufacture paper with pulp.In addition, being coated to paper, can further enhance
The intensity of paper is more conducive to ensureing the smooth production of capacitor.
