Description
Technical field
The invention belongs to battery technology field, is related to a kind of scaling powder and preparation method thereof, more particularly to a kind of plumbic acid
Accumulator plate scaling powder and preparation method thereof.
Background technology
Lead-acid accumulator is mainly by positive plate, negative plate, electrolyte, dividing plate, battery case, battery cover, pole, fill cap etc.
Composition, has the advantages that cheap, service life is long, job stability is high, good reliability.Lead-acid accumulator it is practical with
Come, be widely used in all conglomeraties such as electric power, traffic, communication, power station, emergency power supply as power supply.Recent decades, power supply skill
Art develops rapidly, and novel storage battery is continuously developed out and moves towards market, but lead-acid accumulator still occupies in field of power supplies
Very important status.
The manufacturing technology comparative maturity of lead-acid accumulator, mainly including gold conjugate-cast panel grid-smear-solidification, dry
Dry-burst polishing-combo-pack piece-pole plate weld-fills shell-above lid sealing-terminal welds-and enters groove-acid filling-change
Into-clean the links such as storage.The welding of accumulator plate and bus-bar uses automatic soldering technique mostly, welding quality it is good
The bad performance and used life for directly affecting lead-acid accumulator.The selection of scaling powder determines that pole plate welds matter to a certain extent
Amount, so as to cause to directly affect to the quality of whole lead-acid accumulator.
At present, the scaling powder that domestic and international battery manufacturing firm generally uses is divided into oiliness and water-based two class.Oiliness helps weldering
Agent is prepared, such as generally using organic carboxyl acids such as ethanedioic acid, succinic acid as activator with polyethylene glycol, glycerine etc. for primary solvent
Chinese patent [CN102728817A] is provided using 3 ~ 6wt% ethanedioic acid as activator, and weldering is helped as solvent using glycerine, propyl alcohol
Agent, Chinese patent [CN103521948A] are provided using 5 ~ 10wt% dimethylolpropionic acid as activator, using ethanol, propyl alcohol as
The scaling powder of solvent.Such scaling powder is pretty good to lead-antimony alloy pole plate welding effect, but to lead-calcium alloy pole plate welding effect compared with
Difference, and its winter easily solidifies, reactivity is weaker, it is difficult to cause cast welded mold to be cleared up, solder yield is low.It is existing water-based to help weldering
Agent is prepared, such as Chinese patent mostly with sulfuric acid, phosphorous acid, metaphosphoric acid etc. for activator by solvent of deionized water
[CN103264239A] provides the scaling powder using 10 ~ 15wt% sulfuric acid as activator, and Chinese patent [CN104475712A] carries
The scaling powder using 3 ~ 5wt% phosphorous acid as activator is supplied, Chinese patent [CN103706966A] is provided with 8 ~ 15wt%'s
Metaphosphoric acid is the scaling powder of activator.This kind of water-based scaling powder anti-flammability is preferable but poor with the compatibility of lug, is also easy to produce void
Phenomena such as weldering, dry joint.In addition, the corrosivity such as sulfuric acid as activator is too strong and is easily retained on lug, cause the table of lug
Face forms oxide layer.Effective Storage period of phosphorous acid and metaphosphoric acid is shorter, and phosphorous acid is heated produces severe toxicity in use
Hydrogen phosphide, and the chemicals that metaphosphoric acid is inherently hypertoxic is good for using such scaling powder to operating environment and operating personnel
Kang Zaocheng significant damages.
