Abstract
The utility model relates to an accumulator glass fiber composite separator. The composite separator is a laminar composite plate composed of a base plate layer and a coarse glass fiber thin carpet combined on one side of the base plate. The base plate is a thin plate by mixing glass fiber having diameter of 4-8 mu m, thin glass fiber of 0.3-0.8 mu m and polyethylene or polypropylene organic compound fiber of 13 mu m. In the accumulator, one side of the separator is connected with a cathode of the battery, and one side of coarse glass fiber thin felt is connected with an anode. The separator is characterized by low resistance, large void and small aperture, large pickup current, excellent cold start performance, breakdown- resistance, acid resistance and strong oxidation resistance.
Description
Technical field
The utility model relates to a kind of dividing plate of storage battery, particularly storage battery glass fibre composite diaphragm.
Background technology
Storage battery is the indispensable parts of motor vehicles such as automobile, motorcycle, and battery separator then is the important composition parts that influence battery technology index and useful life.At present, China's battery separator mainly contains the AGM dividing plate, the PP dividing plate, PE dividing plate etc., but the AGM dividing plate belongs to conventional baffle, and technical performance is poor, and picture PE class dividing plate, because China's technology prematurity still, its product overall technology index, still not ideal enough as anti-puncture, resistance to oxidation, acidproof time etc., can not satisfy the demand in market, more be not suitable at high-grade automobile the use of storage battery on the motorcycle.
Summary of the invention
The utility model purpose provides a kind of storage battery glass fibre composite diaphragm, and it has low resistance, big, the anti-puncture of porosity, acidproof corruption, performance that oxidation resistance is strong, and cost is low, and preparation technology is simple.
The utility model battery separator is by substrate and be compound in the laminated composite plate that the raw glass fiber mat of substrate one side is formed, and said substrate is that thick, thin glass fiber and organic synthetic fibers mix the book plate that bonds and form.
Said substrate is to be that the thin glass fiber of the thick glass fibre of 4-8 μ m, 0.3-0.8 μ m and polyethylene or polypropylene organic synthetic fibers mix the book plate that bonding forms by average diameter.Said organic synthetic fibers diameter is 13 μ m.
This dividing plate is compound by substrate and raw glass fiber mat to be layer structure, and as battery separator, comparatively Zhi Mi substrate one side contacts with battery cathode, and raw glass fiber mat one side that contains higher porosity contacts with anodal.Raw glass fiber thin carpet veneer can adsorb the lead plaster powder that comes off in the battery use, prevent to cause the both positive and negative polarity short circuit, increase the service life, substrate layer contains organic fiber, changed the microstructure of dividing plate, adsorbable electrolysis sulfuric acid solution, reduced " concentration polarization " phenomenon effectively, electric current when having improved low temperature discharge greatly, the current discharge time reaches more than the 150s, under cold environment, can effectively improve the continuous spark rate of motor vehicle, stable electric current output is 2 times of conventional baffle, and organic adhesional energy of thickness glass guarantees the whole consistency of coincideing of dividing plate can prevent that active material from coming off, and makes it have good oxidative resistance, after testing, its corrosion resistant time is more than the 80h.This dividing plate has characteristics such as low resistance, porosity is big, the aperture is little, and starting current, and cold starting performance is good, anti-puncture, and acidproof corruption, oxidation resistance is strong, is high-grade automobile, the preferred material of motorcycle battery.
Description of drawings
Fig. 1 is the cross-sectional view of this dividing plate.
Among the figure, 1-substrate layer, 2-raw glass fiber thin carpet veneer.
Embodiment
As Fig. 1, the utility model is used for the glass fibre composite diaphragm of storage battery by dividing plate substrate layer 1 and the compound composite plate of forming of raw glass fiber thin carpet veneer 2 bondings.In storage battery, the substrate 1 of this dividing plate contacts with battery cathode, and raw glass fiber mat contacts with anodal.
The preparation process of the glass fibre composite diaphragm of this storage battery is as follows:
The batching of substrate: with raw glass fiber and thin glass fiber is that 1:1 cooperates with the weight ratio, under the aqueous medium state, is mixed into slurry, adds the polyethylene GZP polyester organic fiber of 5-35% (weight) again.Form the dividing plate substrate through vacuum draw, applying glue then, lamination, compound with the raw glass fibrofelt, and carry out the dehumidifier oven dry, get product.
Claims (1)
1. storage battery glass fibre composite diaphragm is characterized in that the laminated composite plate of being made up of substrate and the raw glass fiber mat that is compound in substrate one side.
