Description
Technical field
The invention belongs to electrolytic capacitor paper fields, and the present invention relates to a kind of preparation sides of super electrolytic capacitor diaphragm paper
Method.
Background technique
Electrolytic capacitor is one of component important in electronics industry, in circuit in addition to having filtering, decoupling and signal
Outside the effect of coupling, special role also is played in special circuit such as circuit for rectifying, power circuit and ac motor start-up circuit.
It is widely used in the fields such as automobile industry, security industry, medical electronics, telecomputer, electronic toy and Industry Control.Electrolysis electricity
Container paper is the gasket material that electrolyte is adsorbed in electrolytic capacitor, its performance directly affects the quality of electrolytic capacitor.
Super electrolytic capacitor is that occur recently as the high speed development of electronics technology and the breakthrough of material science
New power type electronic component.It has higher than general electrolytic capacitor between general electrolytic capacitor and battery
Capacity, thousands of farads can be up to；Higher discharge power more specific than common batteries, discharge current is up to kilo-ampere.Letter
Yan Zhi, it has the capacitance of battery and the fast charging and discharging performance of capacitor, while also with safe and reliable, the scope of application is wide
The features such as.Supercapacitor is in automobile (especially electric car), electric power, railway, communication, national defence and consumer electrical product etc.
Aspect has huge application value and market potential.
Diaphragm paper used in supercapacitor be different from general electrolytic capacitor used in diaphragm paper, due to its use it is special
Tencel fiber be raw material, its intensity is low compared with general electrolytic capacitor diaphragm paper intensity after mashing.Lower tensile strength can be led
It causes to be easy broken end in assembling process, reduces production efficiency, meanwhile, the puncture resistant ability of diaphragm paper can be also reduced, causes to leak electricity
Stream increases, and even results in short circuit.It is therefore desirable to which super electrolytic capacitor diaphragm paper needs higher tensile strength.
Applicant has applied for that Chinese invention patent (CN101696558A) discloses a kind of super electrolytic capacitor paper, this is super
Grade electrolytic capacitor paper be made of pineapple flaxen fiber and tencel fiber copy paper, by weight percentage pineapple flaxen fiber be 10~
80%, tencel fiber is 20~90%.Its paper tightness of super electrolytic capacitor paper of the invention is low, intensity is good, and aperture is small and equal
Even, tightness is low to keep its loss low, not will increase the internal resistance of supercapacitor, and intensity makes it suitable for well the processing of supercapacitor,
The small leakage current that will make supercapacitor in aperture is small, is allowed to be suitble to energy storage, be suitable for use in supercapacitor.
Applicant has applied for that Chinese invention patent (CN108221487A) discloses a kind of low internal resistance super electrolytic capacitor
Paper, the super electrolytic capacitor paper are made of tencel fiber and superfine chemical fiber, and tencel fiber is 10 by weight percentage
~95%, chemical fibre is 5~90%；Chemical fibre used includes polyester fiber, polyolefine fiber, Fypro, polyamides
One of imine fiber, polyacrylonitrile fibre, vinal and spandex fibre or a variety of mixing.
It is all to prepare electrolytic capacitor paper using tencel fiber and other fibers, and illustrating in above-mentioned two patents
Disclosing in book cannot be considered in terms of in intensity, aperture and internal resistance using the electrolytic capacitor paper of independent tencel fiber, therefore individually
Tencel fiber prepares electrolytic capacitor paper and is unable to reach requirement in performance.
Summary of the invention
Present invention aim to address the defects of above-mentioned background technique, first purpose of the invention is to provide a kind of high-strength
Diaphragm of supercapacitor paper is spent, the diaphragm paper aperture is small and uniform, has good absorbent, while anti-tensile with higher
