Description
Technical field
The present invention relates to lead-acid battery additive agent field, and in particular to a kind of polar plate of lead acid storage battery chopped fiber.
Background technology
Lead-acid accumulator has overwhelming superiority always from after invention in electrochmical power source.Because its is cheap, former
Material is easily obtained, using above there is sufficient reliability, the advantages that suitable for heavy-current discharge and extensive ambient temperature range.
Lead-acid accumulator is that application is the most extensive in the world at present, security performance, recuperability highest secondary energy sources.It is same with this
When, Lead-acid Battery Technology passes through years development, and it has had breakthrough than the problems such as energy, cycle life, high/low temperature adaptability,
Chopped fiber plays very important effect in the battery as part important in accumulator plate.
It is 1-4mm chopped fibers that general length is added in the lead plaster for prepare pole plate, and chopped fiber bonds as active material
Skeleton, tridimensional network is formed in pole plate, enhances the mechanical strength of pole plate.After adding chopped fiber, in coated plate process
Middle lead plaster is easily molded, while the cracking and reducing that also prevent to some extent pole plate in solidification drying process assembled
The shedding of pole plate in journey.
Organic fiber and inorfil may be incorporated for preparing the chopped fiber added in the lead plaster of pole plate, due to organic fiber
There are higher intensity and elastic restoring force than inorfil, in the production process of current polar plate of lead acid storage battery, added
Chopped fiber be organic fiber.Polyester fiber, polypropylene fibre, polyacrylonitrile fibre, polyacrylic and polyester fiber, polyethylene fibre,
The organic fibers such as Fypro can be employed as preparing the chopped fiber added in the lead plaster of pole plate.Manufacturer can be according to actual resistance to
The organic fiber of the requirements such as soda acid, heatproof selection suitable material is as the chopped fiber added in the lead plaster for preparing pole plate.
Mentioned in the patent of the Patent No. 201310308516.8 of Tian Neng batteries group application：Same weight addition
Staple fibre number is more, and the net distribution structure in pole plate is good and uniform, really plays enhancing plate strength, prevents pole plate from opening
Split, fall fast, the effect of shedding.
It is short for poly-vinegar that Patent No. 201510545874.X patent discloses a kind of positive electode of lead battery lead plaster chopped fiber
Fiber, length are 2mm~3mm, and single fiber fineness is 1.5D~3D.
But the pole plate of chopped fiber preparation is added, there are still plate strength is low, floating powder is larger to human injury, produced
The problem of loss rate of being given up in journey is high.
The content of the invention
Through experimental studies have found that：Organic short fiber is added in the lead plaster for prepare pole plate, the machinery for enhancing pole plate is strong
Degree.It is because the specific surface area of chopped fiber is relevant with improving the cohesive force between active material, is compared with larger diameter fiber, compared with
Small diameter fibers have the bigger water-wetted surface that obtains to accumulate, and in the preparation process of pole plate, more water can be absorbed, so as to improve
Cohesive force between active material, enhance the mechanical strength of pole plate and reduce the shedding of pole plate.Species with fiber is without too
Important Relations.The length of fiber can influence surface area.Increase is influenceed when length reduces, because greater amount of in every gram of fiber
Staple fiber ends are exposed.But when length and the diameter ratio of chopped fiber are excessive, this increase can be ignored.
And find when the chopped fiber of same weight addition is meticulous, when bar number is excessive, there are some chopped fibers to start to flock together,
It is difficult to be uniformly dispersed so that active material is affected when bonding, and the battery capacity provided declines on the contrary.Also, staple fibre
When number is excessive, fiber volume becomes very big, can take active material volume, and the volumetric constraint that can exceed grid frame on the contrary causes
Plate strength declines.
In order to solve the above-mentioned technical problem, the invention provides a kind of chopped fiber, lead-acid battery electrode plate, Ke Yi great are added into
Width improves plate strength, and effect is original 3 times；Floating powder is effectively reduced, about reduces by 20% or so；Reduce damage of being given up in production process；About
Reduce by 25% or so.
To achieve these goals, the specific technical scheme of the present invention is as follows：Design a kind of polar plate of lead acid storage battery（With）
Chopped fiber, including more root long degree are≤6mm organic fiber, and described organic fiber single fiber fineness is 0.15-0.8D.
It is preferred that single fiber fineness is 0.3-0.6D chopped fiber；
The chopped fiber that further preferred single fiber fineness is 0.35-0.5D；
The chopped fiber that further preferred single fiber fineness is 0.35D；
Above-mentioned polar plate of lead acid storage battery chopped fiber, one in polyester fiber or polypropylene fibre or polyacrylonitrile fibre
Kind or more than one mixing；
Size variation rate≤10% of above-mentioned chopped fiber.
The beneficial effects of the present invention are：Using the present invention, plate strength can be greatly improved, effect is original 3 times；Have
Effect reduces floating powder, about reduces by 20% or so；Reduce damage of being given up in production process；About reduce by 25% or so.

Fig. 3 is the matter loss rate curve synoptic diagram of the present invention.
In figure：1- chopped fibers.
Embodiment：
Technological means, technical characteristic, reached purpose and effect to realize the present invention are easy to understand, with reference to implementation
The invention will be further described for example：
Single fiber long measure mm（Millimeter）, single fiber fineness unit D（Danier）, danier is 9000 meters under official regain
The weight grams of long fiber.Danier abbreviation denier（D）, it is 1 denier that such as 9000 meters of fiber, which weighs 1 gram, when the density of fiber is certain
When, denier is bigger, and fiber is thicker.
The preparation process of pole plate is as follows：
（1）Lead powder and chopped fiber are put in a mixer, add sulfuric acid and water by constantly stirring so as to form suitable coated plate
Lead plaster；
（2）The lead plaster got togather is pressed in above grid and carries out coated plate；
（3）Solidify drying；Positive/negative plate is made.
（4）In the electrolyte of dilute sulfuric acid, positive plate is connected with the positive pole of power supply, the negative plate phase of negative plate and power supply
Even, the lead plaster material on positive plate is made to transform into the active material based on PbO2 with the method for electrochemistry, lead on negative plate
Cream material is converted into the active material based on spongy lead.
Fall-down test：Each embodiment and comparative example pole plate is taken respectively, is finished numbering, is weighed weight.Pole plate is allowed parallel to dry
Neat cement ground, in 1 meter of height, pole plate is set freely to fall.Repeat fall-down test until pole plate occur large area lack cream when, experiment
Stop.Weight change before and after record, record fall 3 times, 6 times, the weight change of 9 times, measure experimental result.
Floating powder test：Example and comparative example pole plate, finish numbering, weigh；With hairbrush gently in polar board surface from pole
Brush 5 times downwards of ear direction, weigh.Floating powder rate=weight difference/pole plate initial weight * 100%.
