Abstract
The separator for the accumulator is composed of the polyvinyl chloride, the deposition silicon dioxide, the additive, the bond and the pore-forming agent according to certain proportioning. The deposition silicon dioxide enhances the wettability and the affinity between the separator and the colloid. The organic solvent as the bond merges and glues the polymer, forming the pieces. The low temp amalgamation makes the separator possess the favorable anti-oxidation and aging resistance. The micropores and the cavities left extracted and volatilized by the solvent under the action of the pore-forming agent constitutes the pores in the separator. The structure of many circuitous pores decides that the separator possesses the minor of the maximum diameter of hole and the highter porosity and the good performance for storing the electrolyte.
Description
Technical field
The present invention relates to a kind of storage battery dividing plate and manufacture method thereof.
Background technology
The domestic dividing plate that is used for colloid battery is sintered type PVC dividing plate mostly at present, the PVC dividing plate is to be raw material with pure polyvinyl chloride, forming method adopts high temperature sintering, pore-forming is formed by PVC particle gap, and the maximum diameter of hole is bigger, and the porosity of hanging down a bit has relatively limited the memory space of electrolyte, and dividing plate is relatively poor aspect non-oxidizability and durability, simultaneously itself is that pure PVC makes, and itself and colloid affinity are unsatisfactory, and the scope of application of dividing plate is wideless.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, provide a kind of on PVC dividing plate basis improved storage battery dividing plate, innovative point is to add in the raw material precipitated silica (SiO
2) to strengthen the wetability and the affinity of dividing plate and colloid, forming method is to adopt amide-type or ketones solvent in the middle of mixing that polymer is fused, bonding in flakes then, this low temperature merges makes dividing plate that good non-oxidizability and durability be arranged, the dividing plate pore-forming leach by the micropore of silicon dioxide own and pore former or volatilization after the hole that stays form, this porous and circuitous structure, determined dividing plate that less maximum diameter of hole is arranged, higher porosity is arranged, and advantage such as the electrolyte storage characteristics is good is applicable to common, low temperature and high temperature automotive type storage battery, traction type accumulator, the fixed storage battery, electromobile battery, seven kinds of storage batterys such as colloid storage battery.This dividing plate is achieved like this: a kind of improved storage battery dividing plate, and the proportioning of its component following (%):
Polyvinyl chloride 30-40
Precipitated silica 55-65
Additive 3-8
Above-mentioned is volume proportion, total amount is 100 parts, adds above-mentioned material total weight in addition:
Adhesive 6%-15%
Pore former 50%-70%
In order to reach desirable micropore, the precipitated silica granularity in the proportioning of the present invention adopts grading composition, is generally:
The above 5-10 of 325 orders
200-325 20-30
100-200 50-58
80-100 8-15
The following 3-8 of 80 orders
Even more ideal grating is:
The above 5-10 of 325 orders
250-325 8-14
200-250 11-16
150-200 35-38
100-150 15-20
80-100 8-14
The following 3-8 of 80 orders
Additive in the compatibility of the present invention mainly is to be used for the stable and anti-old antioxidant of plastics, the general available one or more combination thing of adopting dibutyl ester, dibutylester, antioxidant 264, lead stearate, barium stearate, second base lead sulfate etc., can also add carbon black to reach reinforcement, toning effect, the addition of carbon black is 0.1-0.4 part, is equivalent to account in composition weight 0.03-0.06%.
Pore former in the compatibility of the present invention can be the water-soluble sodium chloride of energy, carbonic acid ammonia, sodium sulphate etc., also can be starch, and what binding agent was selected for use is organic solvent, as amide-type or ketone.
This storage battery is evenly to mix back low temperature compacting by each component of said ratio in flakes with the manufacture method of dividing plate, with solvent pore former and binding agent is leached oven dry more then.Dividing plate of the present invention is preferably selected energy water-soluble pore former and binding agent for use, only need utilize water just they can be leached, and cost is lower; Certainly also can select starch to make pore former, if make pore former with starch, the solvent of its leaching is then selected sulfuric acid etc., binding agent also can be selected organic solvent of ketone, organic solvent of ketone is evaporated by oven dry at last, but with respect to pore former and binding agent that can be water-soluble, these two kinds of selections have strengthened cost undoubtedly.Ya Zhi temperature generally is controlled at 50-90 ℃ in the method, and the best is 60-80 ℃.The dividing plate that makes with this low temperature fusion method of binder swells polymer, non-oxidizability and durability are more superior than PVC dividing plate, the pore-forming porous that the hole that stays after being leached by the micropore of silicon dioxide own and pore former is formed and making a circulation makes dividing plate have less maximum diameter of hole, and higher porosity is arranged, the electrolyte storage characteristics is good, the resistance of dividing plate is lower, and hot strength is better, and wetability is also good especially, this low resistance, porous characteristic can bring storage battery better high-rate discharge ability.
Dividing plate of the present invention because hot strength is good, a side rib of dividing plate except that make rectilinear, can also make diagonal bar bar or S type rib, use to be fit to traction and fixed storage battery that positive plate is a tubular type.Vertical rib can make tubular plate be embedded between the rib, and increases sour replacement amount, reduces the capacity of the acid of positive plate one side; The diagonal bar bar can guarantee that tubular type positive plate one side reaches the acid capacity of design; S type rib can improve the mechanical strength of dividing plate, and the change of the gas flow process that produces because of charging, and plays stirring electrolyte, reduces the effect of electrolyte difference of densities.
This dividing plate and the colloid made from solvent method that the present invention sets forth has wetability and affinity preferably, and resistance is little, porous, and the oxidative resistance height, concrete advantage shows:
1, dividing plate possesses porosity the highest (reaching 70%-75%), low (＜0.0015 Ω .dm of resistance simultaneously
2), maximum diameter of hole little (＜11 μ m), intensity height (＞5Mpa), penetration period short (＜2s), several advantages such as the life-span is long, other dividing plate is not to preponderate at this, accounts for inferior position at that exactly, does not possess above advantage simultaneously.
2, the dividing plate purposes is the widest: it can be used for common, low temperature and high temperature automotive type storage battery, traction type accumulator, fixed storage battery, electromobile battery, seven kinds of storage batterys such as colloid storage battery.And other dividing plate has only three kinds of purposes at most.
3, dividing plate longest-lived: it is used in the fixed life of storage battery and reaches 15-20, and other dividing plate far can not be by comparison.
