Description
Technical field
The present invention relates to lead plaster field, concretely relate to the lead-acid accumulator negative pole lead paste of inhibited oxidation.
Background technology
Positive/negative plate is parts the most crucial in accumulator, and the quality of positive/negative plate directly determines the electric discharge of accumulator
Capacity and service life cycle.Along with the fast development of auto industry, more and more higher to the performance requirement of lead battery, wherein
One of exactly accumulator is had higher requirement in service life under the high temperature conditions.The negative pole of lead-acid accumulator is by plate
Grid and fine grain spongy lead composition, these spongy leads are porous velvet-like materials, and it has more much larger than metallic lead
Surface area again, owing to the spontaneous reduction of material free energy is inclined to, these the tiny lead therefore in charge and discharge process, on pole plate
Grain can gradually be assembled, and makes lead granule become big, makes negative plate porosity really taper into, and negative discharge performance drastically declines, and is formed
So-called negative plate " shrinks ".It addition, in discharge process, negative pole the product sulfur lead plumbate is a kind of high impedance material, its gradually shape
Become one layer of fine and close salt deposit, all and covering on negative plate surface, make lead electrode separate with sulfuric acid electrolyte, lead electrode and sulphuric acid
Contact surface is greatly reduced, and negative discharge performance drastically declines, and forms so-called negative plate and " is passivated ".In prior art, in order to press down
" contraction " and " passivation " of negative pole processed and add additive.But existing cathode lead plaster still cannot solve the sea on negative plate
Continuous shape lead button aoxidizes in atmosphere, the problem affecting service life.
Summary of the invention
It is an object of the invention to provide the lead-acid accumulator negative pole lead paste of inhibited oxidation, to alleviate negative pole in prior art
The problem that spongy lead button on plate aoxidizes in atmosphere, it is achieved slow down lead button oxidation rate, improves service lifetime of accumulator
Purpose.
The present invention is achieved through the following technical solutions:
The lead-acid accumulator negative pole lead paste of inhibited oxidation, it is characterised in that mixed by the raw material of following weight: lead
Powder 100g, sulphuric acid 4～10 g, barium sulfate 0.6 g, humic acid 0.3～0.9 g, white carbon black 0.2 g, acetylene black 0.3 g, tannic extract
0.4g, 1-hydroxy-2-naphthoic acid 0.3g, Colophonium 0.03g.
The problem aoxidized the most in atmosphere for the spongy lead button on lead-acid battery negative pole plate in prior art, this
Invention proposes the lead-acid accumulator negative pole lead paste of inhibited oxidation.In addition to as the Hydrocerussitum (Ceruse) of base material, sulphuric acid, the present invention is also negative
Pole lead plaster with the addition of many kinds of substance as additive:
Barium sulfate, humic acid.Barium sulfate, humic acid belong to conventional cathode lead plaster additive, for suppressing " receiving of negative plate
Contracting " and " passivation ".
White carbon black, for increasing the electric conductivity of negative plate, reduces internal resistance, the most after discharge phase, when lead sulfate crystal shows
When writing increase, the electric conductivity of white carbon black anticathode lead active substance is significantly improved.White carbon black can also increase pole plate simultaneously
Porosity and suction acid amount, the beneficially diffusion of sulfate ion, enhance the real table area of electrode, make negative pole at low temperature environment
Under discharge capacity increase.
Acetylene black, improves electric conductivity and the air filter of active substance of active substance, it is also possible to tie at metallic lead and lead sulfate
Regulate surfactant or the distribution of organic expander during crystalline substance, assemble more surfactant and adsorb at lead and sulfur
Lead plumbate surface, thus improve the volumetric properties of battery and improve the charge acceptance of battery.
Tannic extract, tannic extract is mainly composed of tannin, formation colloid solution soluble in water, and its microgranule has hydrophilic, micelle band
Negative charge, forms complex with Action of Metal Ions, plays the effect of extender, oxygen-inhibiting agent, pore former, binding agent.
1-hydroxy-2-naphthoic acid, uses as oxygen-inhibiting agent main in the present invention, adds 1-hydroxyl in negative plate lead plaster
Base-2-naphthoic acid, it is possible to effectively slow down the aerial oxidation of negative pole spongy lead, increasing storage battery service life.Need note
Meaning, applicant finds after many experiments, after in the present invention, additive includes 1-hydroxy-2-naphthoic acid, it is impossible to add again
Sodium lignosulfonate in conventional additive, otherwise 1-hydroxy-2-naphthoic acid can react with sodium lignosulfonate, generate lignosulphonic acid with
1-hydroxy-2-naphthoic acid sodium, causes two kinds of materials all to lose efficacy, thus causes negative plate performance substantially to reduce.
Colophonium, Colophonium is added in negative plate lead plaster as antioxidant equally, and it can form fat in Metallic lead surface
Oxygen in property protecting film, with air is isolated, thus realizes the effect of inhibited oxidation speed.
Further, the tannin content in described tannic extract is more than or equal to 70%.Guarantee enough tannin contents, so that it is guaranteed that
Using effect.
Further, the content of impurities in described Colophonium is less than or equal to 0.05%.
Further, the purity of described 1-hydroxy-2-naphthoic acid is more than or equal to 90%
The present invention compared with prior art, has such advantages as and beneficial effect:
The lead-acid accumulator negative pole lead paste of inhibited oxidation of the present invention, adds 1-hydroxy-2-naphthoic acid in negative plate lead plaster, it is possible to
Effectively slow down the aerial oxidation of negative pole spongy lead, increasing storage battery service life.Use tannic extract simultaneously, molten by tannin
The colloid solution that Yu Shuizhong is formed, forms complex with Action of Metal Ions, plays extender, oxygen-inhibiting agent, pore former, binding agent
Effect.
