Description
Technical field
The present invention relates to lead accumulator production technical field, more particularly to a kind of lead accumulator dividing plate and lead accumulator.
Background technology
The history in lead accumulator the present in existing more than 150 years, and application field is widely.In recent years, electric car was preferable with its
Performance of riding instead of walk, relatively low storage space requirement and outstanding price advantage in China's fast development, have benefited from this, battery production
Industry has also obtained rapid development.
Lead accumulator is mainly made up of positive and negative pole plate and dividing plate, housing, electrolyte, pole etc..In lead accumulator every
Plate not only plays a part of separated positive/negative plate, and requires that dividing plate has that porosity is high, aperture is small, oxidation resistance is strong, can
Absorb and keep enough electrolyte, there are the characteristics such as good compression rebound.If the clapboard aperture of lead accumulator is too big easy
The penetration of lead dendritic crystal dividing plate of accumulator plate is caused to cause the short circuit of battery, the compression resilience difference of dividing plate can cause lead accumulator
Assembling pressure is too low and fail after the discharge and recharge of a period of time is carried out, and the acid difference of suction of dividing plate can cause lead accumulator circulating
During acid deficient and fail.The dividing plate of current lead accumulator is substantially AGM dividing plates, and its main component is glass fibre.Due to glass
Glass fiber is extracted at random by flame method, and the fineness and length of its fiber are uneven, and current glass fibre is most thin
0.8 μm -1.59 μm can be accomplished, cause that the maximum diameter of hole of the glass fibre separator prepared is larger, pore-size distribution is uneven,
And compression resilience is poor.
In order that the performance of AGM dividing plates is more excellent, some additives can be typically added into AGM dividing plates.Such as：
Authorization Notice No. discloses a kind of AGM baffle of storage battery and its preparation for CN103855346B Chinese invention patent
Method, the AGM baffle of storage battery includes high alkali glass cotton, medium-alkali glass fibre, bicomponent polyester fiber, contains SiO2Particle
Glue, the high alkali glass cotton, medium-alkali glass fibre, bicomponent polyester fiber, contains SiO2The percentage by weight of the glue of particle is
81~87: 2.8~4.6: 1.8~3.7: 8.3~11.4.
Authorization Notice No. discloses a kind of baffle plate of lead acid storage battery and its system for CN 102623659B Chinese invention patent
Preparation Method, the dividing plate is using glass fibre as principal component, also comprising the vistanex that 10%~20% fusing point is 100~200 DEG C
Fiber.
Publication No. CN104852002A Chinese invention patent discloses a kind of baffle plate of lead acid storage battery, including quality hundred
Point than be 85-95% ultra-fine fibre glass, mass percent be 4-10% polyester fiber, mass percent is 1-5% vinegar
Sour fiber.Preparation method is to add polyester fiber and acetate fiber after ultra-fine fibre glass is carried out into mashing 5-10 minutes, then is beaten
Slurry carries out shaping handsheet after 8-12 minutes, at the uniform velocity into drying system, is dried at 160-250 DEG C, winding cutting.
Sea-island fibre is a kind of a kind of material being scattered in polymer in another polymer, is disperseed in fibre section
It is in mutually " island " state, and parent is then equivalent to " sea ", in terms of the cross section of fiber is a kind of composition with fine and scattered state
Surrounded by another composition, there are many island as marine.Its " island " in the axial direction of fiber is continuous, close with " sea " composition
Collection, it is equally distributed.In process of production, it has the fiber number of conventional fibre, but " sea " composition is dissolved away with solvent, then may be used
Obtain collecting the superfine fibre beam of pencil.According to the general classification of fiber, after sea-island fibre separation, filament number only 0.005D, category
Superfine fibre, conventional spinning can not possibly be accomplished, therefore it has the characteristic that general fiber can not possibly have.Sea-island fibre has uniqueness
Performance, with acid resistance is good, crimped resilient is good, the advantages of capillary wick effect is good.
The content of the invention
The present invention is larger for the maximum diameter of hole of AGM dividing plates in the prior art, and pore-size distribution is uneven, and compression rebound
Property difference the problem of there is provided a kind of aperture it is small, inhale the lead accumulator dividing plate that acid amount is high, durable pressure is big, tensile break strength is big.
A kind of lead accumulator dividing plate, the composition of the lead accumulator dividing plate includes glass fibre and COPET sea island filaments, its
In, the COPET sea island filaments are obtained by PA/COPET sea-island fibres after molten sea processing.PA/COPET sea-island fibres refer to marine origin
It is polyamide fibre (PA) to divide, and island component is the sea-island fibre before the molten sea of modified dacron (COPET), and sea component PA therein is dissolved
