Description
Technical field
The present invention relates to a kind of accumulator material and preparation method, particularly automobile start belongs to the battery technology field with dividing plate in the lead-acid battery and preparation method thereof.
Background technology
Dividing plate is an important set member in the lead-acid battery, dividing plate places between the battery plus-negative plate plate, both can prevent that electrode was short-circuited in electrolyte, simultaneously guarantee again that electrolyte had good electrical conductivity between both positive and negative polarity, function such as also have the plate buckling of alleviating, prevent that active material from coming off.Along with the develop rapidly of auto industry, more and more higher to the performance requirement of starting lead acid battery, as the dividing plate of one of lead-acid battery four big assemblies, the quality of its performance directly affects the height of lead acid accumulator quality.At present, the starting lead acid battery dividing plate mainly contains five kinds on PE, PVC, PP, rubber and 10G dividing plate etc., the characteristics of 10G dividing plate are: the porosity height, resistance is little, impurity content is low, and good anti-corrosion and heat-resisting quantity, can effectively improve the performance and the life-span of storage battery, and, the phenomenon that dividing plate can not occur wearing out, also be not subjected to the influence of high temperature, can under any weather conditions, use.10G dividing plate base paper is to use glass fibre cotton, is equipped with a small amount of synthetic fibers and latex, with the wet method moulding of manufacturing paper with pulp, and then basic paper is carried out impregnation, reinforcement, drying, cuts into the dividing plate of various sizes.The processing mode of above-mentioned wet moulding can be given this kind dividing plate porous, low-resistance characteristic, and glass fibre cotton is main material, gives the characteristic that this kind dividing plate is corrosion-resistant, high temperature resistant and impurity content is low again.But this dividing plate has the shortcoming that the aperture is big, intensity is low, easily causes dividing plate " infiltration " and causes the pole plate short circuit, causes storage battery to be scrapped; Or pierced through and press against brokenly by the burr on the pole plate, pimple, cause storage battery to be scrapped, when therefore using this kind dividing plate, very strict to the quality requirement of pole plate, pole plate must not jagged and pimple, and pole plate can not be crooked, otherwise all can cause damage, and cause battery failure dividing plate.
Summary of the invention
Technical problem to be solved by this invention provides lead acid start accumulator separator and the preparation method that a kind of aperture is little, intensity is high, porosity is high, resistance is little.
The alleged problem of the present invention is solved by following technical scheme:
A kind of aluminic acid start accumulator separator, its special feature is: described clapboard raw material is made up of following weight unit's matter: ultra-fine fibre glass cotton 100, polyester fiber 10～15, wet strength agent 0.2～0.3, precipitation latex 6～7, PAMC 0.3～0.4, wherein, the cotton diameter of described ultra-fine fibre glass is 1.0～1.4 μ m, and described polyester fiber diameter is 6～9 μ m.
The preparation method of above-mentioned lead acid start accumulator separator, it is undertaken by following operation:
A. pulping: take by weighing ultra-fine fibre glass cotton, polyester fiber and wet strength agent by aforementioned barriers raw material proportioning, join in the pulper, add entry slurry concentration is adjusted to 0.45～0.55%, it size degradation is become the homodisperse slurry of fiber, pump in the reserve pit standby;
B. slurry is handled and carried: the slurry slagging-off that size degradation is good then by aforementioned barriers raw material proportioning, successively adds precipitation latex and PAMC, and with concentration dilution to 0.03～0.05% of slurry, is transported to production line of paper machine;
C. basic paper is manufactured paper with pulp: slurry at production line of paper machine according to paper technology through moulding, drying with batch, manufacture paper with pulp into dividing plate base paper;
D. dividing plate processing: basic paper is at the dividing plate forming production line, through dipping, reinforcement, drying, cut, case, is processed into the starting lead acid battery dividing plate.
Dividing plate of the present invention be big at common 10G clapboard aperture, intensity is low, easily cause dividing plate " infiltration " and cause the drawback of pole plate short circuit and design, determine the prescription of dividing plate base paper through repetition test, it has kept common 10G dividing plate porosity height, resistance is little, strong advantage conforms, reduce the aperture of dividing plate, improved the intensity and the adaptive capacity of dividing plate.The maximum diameter of hole of improving rear bulkhead reduces by 30～50%, and tensile strength improves nearly one times, and it is about 80% that dried breakdown strength improves, and the corrosion breakdown strength improves about 65%.Dividing plate of the present invention can effectively reduce the probability of " infiltration " of dividing plate because of increasing substantially aperture and intensity index, improves the anti-of dividing plate and pierces through and the friction resistant performance, has improved the life-span of battery and the starting performance of storage battery.
Embodiment
10G dividing plate of the present invention is applicable to lead acid start accumulator, problems such as it is big at common 10G clapboard aperture, intensity is low have been carried out the prescription improvement, be embodied in following three aspects: 1. reduce the glass fibre cotton diameter, by the glass fibre cotton of 1.6～2.0 common μ m diameters, be improved to the ultra-fine fibre glass cotton of 1.0～1.4 μ m diameters; 2. reduce the diameter of polyester fiber: 9～12 μ m diameters by common are improved to 6～9 μ m; 3. the addition that improves polyester fiber by: 4～8% (to glass fibres) originally are improved to 10～15% (to glass fibres).Through the dividing plate reservation porosity height of making after the above-mentioned improvement, the advantage that resistance is little, overcome the defective that the aperture is big, intensity is low, form a kind of lead acid start accumulator separator with premium properties.Following table is a dividing plate Performance Detection situation of the present invention:
| Testing result | Primary standard | Remarks | |
| Maximum diameter of hole μ m | 16 | ≤30 | Significantly less than standard |
| Tensile strength kN/m | 2.2 | ≥1.6 | It is difficult to reach mark |
| Do breakdown strength g | 600 | ≥250 | Well beyond standard |
| Corrosion breakdown strength g | 500 | ≥200 | Well beyond standard |
| Porosity % | 87.8 | ≥85 | Reach standard |
As seen from the above table, dividing plate of the present invention maximum diameter of hole reduces significantly, and the maximum diameter of hole mainly influences the penetration degree of plate active material in the storage battery, after infiltration occurring, can make the positive/negative plate short circuit and cause scrapping of storage battery, after the aperture reduces, can lower the infiltration of dividing plate greatly.In addition, the raising greatly of breakdown strength can effectively improve the anti-penetration ability of dividing plate, because the variation of volume can take place when discharging and recharging pole plate, dividing plate is had extruding force, has improved breakdown strength, has just improved the crush resistance of dividing plate, has also improved the life-span of battery.Have, the porosity of common dividing plate is generally below 60% again, and the porosity of dividing plate of the present invention surpasses 85%, therefore can improve the starting performance of storage battery greatly.
