Abstract
The invention discloses a micro-structure bird nest-imitating AGM partitioning plate which comprises branched Y-shaped ultrafine glass fibers and un-branched glass fibers. The diameter of the Y-shaped glass fibers is 2-10 mu m, the length is 1-10 mm, and the Y-shaped glass fibers account for 5-25 percent by weight in the partitioning plate. The diameter of the un-branched glass fibers is 0.1-4 mu m, the length is 0.3-10 mm, and the un-branched glass fibers account for 75-95 percent by weight in the portioning plate. From the aspect of a bionics principle, by imitating a bird nest structure, the invention provides a micro-structure bird nest-imitating AGM partitioning plate which is stable in structure, good in fiber web uniformity, good in rebound resilience and antiknock characteristic, and high in strength; and the partitioning plate is stable in chemical property, free from generating any harmful substance, and strong in capacity of absorbing and keeping an electrolyte, thereby greatly prolonging the service life of a storage battery.
Description
Technical field
The present invention relates to a kind of AGM dividing plate, particularly the imitative Bird's Nest AGM dividing plate of a kind of micro-structural.
Background technology
AGM dividing plate is absorption type super glass wool dividing plate, the homogeneous laminar flexible material that the ultra-fine fibre glass that is normally 0.5～3 μ m by diameter makes by wet therapy forming process.At present, AGM dividing plate has become the main flow dividing plate of battery industry, and is described as battery industry indispensable " century material ".AGM dividing plate is except preventing the short circuit between both positive and negative polarity in battery, the required electrolyte of both positive and negative polarity generation chemical reaction while adsorbing battery charging and discharging again, the oxygen generating when battery generation chemical reaction is provided is penetrated into the passage of negative pole, but also require dividing plate can better bear the active material active force causing that expands, prevent that active material from coming off, and reduce the degeee of stratification of electrolyte.In addition, the overall structure of dividing plate should have certain mechanical strength and good stability.
AGM dividing plate is one of key factor affecting lead acid accumulator useful life.In actual application, because AGM dividing plate long period of soaking is in acid solution, the glass fibre in dividing plate is subject to acid liquid corrosion and ruptures, thereby diaphragm structure is gone to pot, the phenomenon such as subside; In addition, the adhesion in AGM dividing plate between ultra-fine fibre glass is very little, and in the time that the surface tension of water is greater than interfibrous adhesion, the adhesion between ultra-fine fibre glass is by destroyed, and diaphragm structure also will go to pot; Moreover dividing plate, in application process, can constantly suffer mechanical shock, also makes dividing plate easily subside.Once and diaphragm structure goes to pot and even subside, can greatly shorten the useful life of storage battery.Therefore, how to prepare the AGM dividing plate with rock-steady structure the development of storage battery is had to vital impact.
Birds are woven into a spherical nest with branch fiber, grass blade or withe between the high treetop withe wooden fork of height, and can carry out with saliva or earth bondingly, build the Bird's Nest with network-like framework.This special structure can evenly spread to external force everywhere Bird's Nest in the time being subject to external force, and has powerful steadiness, shock resistance and weatherability.
Granted publication number is the core material of vacuum heat insulation plate that the Chinese utility model patent of CN 202852336 U discloses the imitative Bird's Nest of a kind of micro-structural, this core by inorfil cotton and inorfil cotton around aperture form, be a kind of heat-barrier material, can be used as core material of vacuum heat insulation plate.This kind of core mineral wool is evenly distributed, Stability Analysis of Structures, but is not suitable for the manufacture of AGM dividing plate.
Mandate publication number is that the Chinese utility model patent of CN 202259508 U has proposed a kind of AGM baffle of storage battery, for bag-shaped, is made up of one deck thin glass fiber cotton and one deck raw glass cellucotton, and thin glass fiber cotton is in bag inner side, and raw glass cellucotton is in bag outside.It is poor that this AGM dividing plate efficiently solves in prior art the anti-gas impact capacity of AGM dividing plate, easily produces the problem of dendrite short circuit, thereby extend the useful life of storage battery, but this kind of dividing plate still exists structural instability, the poor problem of resilience.
The present invention, from bionics principle, copies Bird's Nest structure, has proposed the AGM dividing plate of a kind of Stability Analysis of Structures, fibre net homogeneity is good, resilience the is good similar Bird's Nest of micro-structural.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, from bionics principle, copy Bird's Nest structure, propose that a kind of Stability Analysis of Structures, fibre net homogeneity are good, the AGM dividing plate of resilience and the good similar Bird's Nest of micro-structural of shock resistance, thereby service lifetime of accumulator is improved greatly.
In order to realize object of the present invention, adopt following technical scheme: a kind of micro-structural is imitated Bird's Nest AGM dividing plate, it is characterized in that this AGM dividing plate by " Y " font ultra-fine fibre glass of bifurcated and not the glass fibre of bifurcated form.
Described " Y " font glass fiber diameter is 2～10 μ m, and length is 1～10mm, and in dividing plate, percentage by weight is 5～25%.
Described not bifurcated glass fiber diameter is 0.1～4 μ m, and length is 0.3～10mm, and in dividing plate, percentage by weight is 75～95%.
Compared with prior art, the present invention has following beneficial effect:
(1) dividing plate is made up of pure glass fibre, and stable chemical performance does not produce any harmful substance, absorbs, keeps electrolyte ability strong;
(2) on the basis of ultra-fine fibre glass, add thick long glass fibres and made skeleton, improve diaphragm strength;
(3) the imitative Bird's Nest structure that " Y " font glass and thick roving glass fiber form, makes AGM diaphragm structure more firm, and shock resistance improves greatly, thereby has improved the useful life of storage battery.
Brief description of the drawings
Fig. 1 is the structural representation of the imitative Bird's Nest AGM dividing plate of a kind of micro-structural.
" Y " font glass fibre that diagram 10 is bifurcated; 20 is thick long glass fibres.
