Description
Technical field
The present invention relates to a kind of preparation method of AGM dividing plate, particularly the preparation method of 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 of high power, 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 AGM diaphragm structure of the similar Bird's Nest of micro-structural is stablized, fibre net homogeneity is good, resilience is good, but its preparation method is not yet ripe.The present invention proposes the preparation method of the imitative Bird's Nest AGM dividing plate of a kind of micro-structural, and can effectively prevent that fiber bifurcation structure in pulping process of bifurcated from going to pot.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, propose that a kind of Stability Analysis of Structures, fibre net homogeneity are good, the preparation method of the AGM dividing plate of resilience and the good similar Bird's Nest of micro-structural of shock resistance, this preparation method can effectively prevent that fiber bifurcation structure in pulping process of bifurcated from going to pot.
In order to realize object of the present invention, adopt following technical scheme: the preparation method of the imitative Bird's Nest AGM dividing plate of a kind of micro-structural, is characterized in that slurry adopts jet mixing method to be prepared, and comprises the step of following order:
(1) take 5～20 parts of " Y " shaped forked ultra-fine fibre glasses, make slurry;
(2) take 80～95 parts of not bifurcated ultra-fine fibre glasses, make slurry;
(3) start rotation injector mixer, above-mentioned two kinds of slurries are sprayed in injector cylindrical tube by injector respectively, vertical drop, and fully mix in injector, incorporation time is 5～15min;
(4), after mixing, to the slurry removal of impurities that removes the gred, and carry out twice moulding dehydration;
(5) dividing plate matrix is dried, be cooled to after room temperature, to its rolling, cut, obtain described AGM dividing plate.
Described cylindrical tube diameter is 200～2000mm, and length is 1～10m.
On described cylindrical tube axis, there is a vertical rotary post, and with reverse agitating function blade.
The interior column spinner rotary speed of described cylindrical tube is 100～1000r/min.
Compared with prior art, the present invention has following beneficial effect:
(1) this preparation method can effectively prevent that fiber bifurcation structure in pulping process of bifurcated from going to pot;
(2) the AGM diaphragm structure that prepared by the method is more firm, and shock resistance improves greatly, thereby has improved the useful life of storage battery.
