Abstract
The invention discloses a kind of ultracapacitor resistance and wear composite diaphragm material, it is prepared by the raw materials in: vinal 35 40, polypropylene fibre 33 35, polyacrylonitrile powder 10 13, acetone 30 32, N, N dimethylformamide 72 75,70 DEG C of water-soluble PVA fibers 8 10, N methyl pyrrolidone 34, flyash 8 10, Ludox 34, aminopropyl triethoxysilane 0.8 1, phenolic moulding powder 34, nano titanium oxide 45, sodium hexameta phosphate 0.9 1.The present invention adds in the preparation of product by the flyash after processing, phenolic moulding powder, nano titanium oxide etc., the intensity of product and anti-breakdown performance can be strengthened, the composite diaphragm material porosity that the present invention makes is high, even aperture distribution, there are good insulating properties, dielectric properties, the most reinforcing preferably, resistance to sparking can be good.
Description
Technical field
The present invention relates to capacitor diaphragm technical field, particularly relate to a kind of ultracapacitor resistance and wear composite diaphragm material
Material.
Background technology
Ultracapacitor is the accumulator of a kind of great market competitiveness, owing to it can realize quick charge, big electric current
Electric discharge, and there is the charge lifetimes of more than 100,000 times, in some need the application of high-multiplying power discharge in short-term, occupy critical role.
Hybrid vehicle and electric automobile also result in the requirement of electrical source of power in worldwide that this is new to ultracapacitor
The extensive attention of type energy storage device.In the composition of ultracapacitor, electrode, electrolyte and the diaphragm paper property to ultracapacitor
Conclusive impact can be played.Electrode and the electrolyte of ultracapacitor is the focus studied at present, but people are for barrier film
Research and attention rate the highest.
The diaphragm paper of ultracapacitor is between two porous carbon electrodes, and complete wetting is at electrolyte together with electrode
In, during repeated charge, play the effect of isolation, stop electronics conduction, prevent between the two poles of the earth, contacting the inside caused short
Road.This just requires that diaphragm material is the insulator of electronics, has good isolation performance, and its hole should be as far as possible less than electricity
The minimum grain size of pole surfactant.The necessary aperture of the preferable diaphragm paper of isolation performance is little, so can make the circulation of electrolyte
Property decline, battery charging and discharging hydraulic performance decline;And electrolyte to be impregnated with rate higher, ion is by the good diaphragm material often hole of property relatively
The most more, easily cause and between the two poles of the earth, contact the internal short-circuit caused.The advantage of ultracapacitor maximum is charge/discharge rates
Hurry up, can be with high power discharge, therefore, diaphragm material will thinner towards thickness, porosity is higher, aperture is less and is more evenly distributed
Contour performance trend development.
The material being currently used for diaphragm of supercapacitor mainly has cellulosic separator paper and conventional batteries barrier film, high-performance every
Film paper manufactures technical difficulty, and price is high;Conventional batteries membrane thicknesses is thicker, and porosity is low, poor to electrolyte affinity, and quiet
Electro spinning nanometer fiber membrane manufacturing technology is simple, low cost, and barrier film porosity is up to 90%, good to electrolyte affinity, but lacks
Point is that intensity is the highest.If cellulosic separator paper can be combined with electrospun fibers film, learning from other's strong points to offset one's weaknesses, can be become
The composite diaphragm material that this is low, porosity is high, intensity is big.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of ultracapacitor resistance wear compound every
Membrane material.
The present invention is achieved by the following technical solutions:
Composite diaphragm material is worn in a kind of ultracapacitor resistance, is prepared by the raw materials in: vinal 35-
40, polypropylene fibre 33-35, polyacrylonitrile powder 10-13, acetone 30-32, DMF 72-75,70 DEG C water-soluble
PVA fiber 8-10, N-Methyl pyrrolidone 3-4, flyash 8-10, Ludox 3-4, aminopropyl triethoxysilane 0.8-1, electricity
Wood powder 3-4, nano titanium oxide 4-5, sodium hexameta phosphate 0.9-1.
According to the diaphragm of supercapacitor material of a kind of environment-friendly degradable described in claims 1, by following concrete grammar
It is prepared from:
(1) acetone is mixed homogeneously at normal temperatures with DMF, add polyacrylonitrile powder, with 100 revs/min
Speed stirs 3 hours at normal temperatures, formed polyacrylonitrile spinning solution, receiving range be 20cm, voltage be 25kV, feed flow speed
Rate is to carry out electrostatic spinning 2 hours under conditions of 1mL/h, spins out the polyacrylonitrile nanofiber film that thickness is 10 μm stand-by;
(2) polypropylene fibre is mixed with vinal, add appropriate water, put in beater, carry out by 2% concentration
It is dispersed into fibrous suspension, adds 70 DEG C of water-soluble PVA fibers, be heated to 70 DEG C while stirring with the speed of 1000 revs/min, until
It is stand-by that 70 DEG C of water-soluble PVA fibers are completely dissolved formation mixing suspension;
(3) flyash is dried, put in ball mill, add aminopropyl triethoxysilane, be heated to 60 DEG C, mixing and ball milling 90
Minute, taking out after cooling, mix with the Ludox being dissolved in 8 times amount water, ultrasonic disperse is centrifugal after 40 minutes to be stood, and filters, will
To solid powder dried and phenolic moulding powder, nano titanium oxide are put in high speed mixer, be heated to 130 DEG C, with 1000 turns/
The speed divided stirs 20 minutes, discharging, pulverizes, and crosses 600 mesh sieves, obtains reinforcer;
(4) mixing suspension that will obtain in step (2) adds reinforcer, the polyacrylamide emulsion that step (3) obtains
And remaining residual components, continuously add appropriate water, stir 30 minutes with the speed of 600 revs/min, forming online concentration is
The slurry of 0.1wt%, uses wet therapy forming process by above-mentioned slurry feeding paper machine through wet end and press section drainage and formation, then
Electricity consumption hot blast is dried 10 minutes, then uses hot forming machine to obtain non-weaving cloth base fabric with the temperature heat pressure adhesive of 135 DEG C to treat
With;
