Description
Technical field
The present invention relates to a kind of AGM partition boards, more particularly to a kind of AGM partition boards with adhesion micro-structure.
Background technology
AGM partition boards, that is, absorption type super glass wool partition board, are typically led to by a diameter of 0.5~3 μm of ultra-fine fibre glass
The homogeneous laminar flexible material of prepared by crossing wet therapy forming process.AGM partition boards have excellent machinery, physics and change
Performance is learned, is that battery industry is indispensable " century material ", and has become mainstream partition board.AGM partition boards are widely used in plumbic acid
In accumulator, it is referred to as the third pole of valve controlled sealed lead-acid accumulator.
AGM partition boards be influence lead-acid accumulator service life an important factor for one of, partition board in addition in battery to be prevented just
Short circuit between cathode, the electrolyte needed for chemical reaction occurs for positive and negative anodes when adsorbing battery charging and discharging again, provides battery hair
The oxygen generated when biochemical reaction penetrates into the channel of cathode, but also requires partition board that can preferably bear active mass expansion
Caused active force, prevents active material from falling off, and reduces the degeee of stratification of electrolyte.In addition, the overall structure of partition board is answered
When with certain mechanical strength and good stability.
In actual application, since AGM partition board long period of soaking is in acid solution, the glass fibre in partition board is easily by acid solution
Corrosion is broken, so that diaphragm structure goes to pot, phenomena such as collapsing.In addition, partition board is in application process, it can not
Break by mechanical shock, but also partition board easily collapses.Once and partition board starts to collapse, and can greatly shorten the use longevity of accumulator
Life.Therefore, how effectively to consolidate AGM diaphragm structures has vital influence to the service life for extending accumulator.
The Chinese utility model patent of 202259508 U of Publication No. CN is authorized to propose a kind of AGM baffle of storage battery,
It to be bag-shaped, is made of one layer of thin glass fiber cotton and one layer of raw glass cellucotton, for thin glass fiber cotton on the inside of bag, raw glass is fine
Vinylon and cotton blend is on the outside of bag.The AGM partition boards efficiently solve the anti-gas impact energy force difference of AGM partition boards in the prior art, are also easy to produce dendrite
The problem of short circuit, to extend the service life of accumulator, but that there are diaphragm strengths is low, rigidity is small, assembly is difficult, structure is unstable
Fixed problem.
The Chinese invention patent that application publication number is 103855346 A of CN proposes a kind of AGM baffle of storage battery and its system
Preparation Method, the AGM baffle of storage battery include high alkali glass cotton, medium-alkali glass fibre, bicomponent polyester fiber, contain SiO2Particle
Glue, the high alkali glass cotton medium-alkali glass fibre, bicomponent polyester fiber, contains SiO2The weight percent of the glue of particle
It is 81~87: 2.8~4.6: 1.8~3.7: 8.3~11.4.This kind of preparation method can realize post forming, made partition board synthesis
Functional but complicated with glue and blending process, drying time is longer, is unfavorable for realization and produces efficiently.
Application publication number is that the Chinese invention patent of 103545470 A of CN discloses a kind of colloidal lead-acid storage battery partition board,
And the production method of this kind of colloidal lead-acid storage battery partition board, it is coated with polymer colloid layer in AGM baffle surfaces, by anion
Polyacrylamide water-soluble polymer and water are mixed by weight for 5~10: 1 ratio, and carry out plastic processing and high score is made
Polymer colloid is coated in AGM baffle surfaces, forms polymer colloid layer by sub- colloid, which is
Then 0.01~1mm carries out drying obtained colloidal lead-acid storage battery partition board.The partition board efficiently solves colloidal electrolyte in plumbic acid
Non-uniform problem is perfused in storage battery production process, but polymer colloid used is water-fast, acid resistance is poor, and diaphragm structure is still unstable
It is fixed.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of AGM partition boards with adhesion micro-structure, should
Kind AGM diaphragm structures are more stable, are amenable to long-term acid soak and mechanical shock, so that accumulator is with longer
Service life.
In order to achieve the object of the present invention, it adopts the following technical scheme that：A kind of AGM partition boards of adhesion micro-structure, feature
It is in the AGM partition boards that glass fibre has adhesive particle with glass fibre lap-joint.
The glass fiber weight percentage is 90~99%, wherein a diameter of 0.5~1.2 μm of thin footpath glass fibre
Weight percent is 65~100%, and particle size glass fiber weight percentage is 0~35% in a diameter of 3~10 μm.
The adhesive particle be polyethylene fibre glue, polypropylene fibre glue, polyester fiber glue, weight account for AGM every
The percentage of plate is 1~10%.
The adhesive particle size is 2~15 μm.
The fracture strength of two fibers of the adhesive particle bonding is 2000~5000MPa.
Compared with prior art, the present invention has the advantages that：
(1) it is mutually bonded by meldable fibre glue between the glass fibre intersected, this binding force is larger so that AGM partition boards
It will not arbitrarily be moved and made since fiber surface is smooth as the fiber in common AGM partition boards by when the bulbs of pressure in battery
At aperture and elastic variation；
(2) structure of this stick to each other is but also the ability of AGM partition board resistance to mechanical vibrations greatly improves, and partition board is because of machinery
Shock structure will not cause integrally-built collapse by local damage；
It (3), will not shadow even if partition board makes part glass be broken because of acid liquid corrosion during prolonged application
It rings and arrives its overall structure, substantially increase the chemical stability of partition board；
(4) due to being filled with meldable fibre glue between the glass of AGM partition boards, this makes the pore of partition board become more curved
Song, to which the growth of controllable lead dendritic crystal penetrates；
(5) micro-structure of this stabilization can form unimpeded oxygen diffusion paths, improve oxygen combined efficiency, and reducing battery makes
With dehydration in the process；
(6) structure makes AGM partition board mechanical strengths be improved, and can also keep preferably assembling after electrolyte is added
Pressure will not be caused by battery performance deficiency caused by collapsing, partition board also can be improved to the holding power of pole plate, prevent active matter
Matter falls off.
