Description
The present invention relates to a kind of alloy material, particularly a kind of superlow antimony alloy material that is used for the fully closed maintenance-free lead accumulator grid.
In order to improve the performance of closed lead acid accumulator, people have carried out continuous research to the composition proportion of its grid alloy, have found that the antimony in the lead 2-base alloy has crucial effect.It can make the anode plate grid surface generate the good PbO of electroconductibility
2, battery life is prolonged, but when Sb content when being higher than 0.5%, alloy is at H
2SO
4Have a large amount of hydrogen evolution in the solution, this alloy can only be used in covering open type battery, and reduce the Sb content in the alloy, can cause that again the mechanical property of alloy descends, must add other composition and strengthen.
DE-OS-3042011A discloses a kind of by Pb, Sb(0.1-3.5% in the prior art), Te, S, Se, Zn, Ag, the alloy material for slab lattice that As and Be form.Wherein Sb content is 0.5% when above, it cannot be used as the closed accumulator grid, for Sb content when the 0.1-0.5, can satisfy the requirement of the hydrogen amount of analysing, yet since this alloy be to use As metacrystal agent strengthen, its severe toxicity is to the disadvantageous effect of operator and environment, and As generally is limited in below 0.4% and uses, and at this moment this hardness of alloy can not reach HB1.274 * 10
-2The requirement of MPa.Therefore this alloy is difficult as the sealed lead-acid battery grid, in addition, the metacrystal agent of extensively adopting at present, the healthy and contaminate environment that not only endangers the workman based on As, it has also seriously influenced the toughness of alloy simultaneously, makes the production technique decline of material.
The objective of the invention is to propose a kind of antimony amount that contains below 0.5%, and use the slab lattice alloy material for sealed lead accumulater of alkali metallic sodium, to overcome weak point of the prior art as reinforcer.
The object of the present invention is achieved like this.
Super low antimouy alloy material of full sealed lead-acid accumulator grid is by Pb, Sb, and Na becomes to be grouped into Se.The weight percent of the chemical composition content of alloy is:
Pb 99.3-99.61;
Sb 0.3-0.5;
Na 0.04-0.1;
Se 0.05-0.1。
This alloy melts in common lead pan, and the cast panel temperature is controlled at 490-520 ℃ of scope.
The present invention is controlled at 0.3-0.5% with antimony content, to keep lead 2-base alloy (Pb-0.3-0.5%Sb) to have higher overpotential of hydrogen evolution, because containing antimony is that the scope endobasal-body of 0.3-0.5% is αGu Rongti substantially, the appearance of no β phase, because monophasic stable electrochemical property, so the overpotential of hydrogen evolution of this alloy can satisfy the requirement of enclosed cell fully near pure lead.
Because the poor mechanical properties of Pb-0.3-0.5%Sb alloy, the present invention adopts alkali metallic sodium to strengthen.As everyone knows, the solubility with temperature of Na in lead raises and increases, and the solubleness of Na approaches zero under room temperature state, and the Na that is dissolved in the lead base body during high temperature is with Pb
3The form of Na is separated out, and disperse is distributed in the lead base body, has played the effect of dispersion-strengthened, adds the Na of 0.04-0.1% in Pb-0.3-0.5%Sb, and the mechanical property of material is obviously improved, and has satisfied the requirement of enclosed cell to the mechanical property of materials.
Because the speed of cooling of alloy material in actual casting is produced is very fast, can cause brilliant prolongation of skill of alloy, casting crack appears when serious, the present invention adopts the selenium processing of going bad for this reason, this is that these particles become the core of the heterogeneous forming core of alloy because solubleness hurried decline along with decrease of temperature of selenium forms a lot of second phase particles in the fused alloy, its rotten result has formed the alloy structure of even compact.
The content of sodium and selenium is very little in the present invention, and all forms mutually with second and be present in the lead base body, so the overpotential of hydrogen evolution of alloy is not had influence substantially, can satisfy the requirement of closed accumulator.
The present invention has the following advantages:
1, do not have arsenic, no cadmium in this alloy material, do not have the harm of arsenic, cadmium human body.
2, the physical strength of this alloy material can reach σ b4.988 * 10
-3Mpa, hardness can reach HB1.3916 * 10
-2Mpa all reaches the level of high antimony (6.5%Sb), and alloy also has higher advantages such as overpotential of hydrogen evolution simultaneously, therefore can be as the positive and negative electrode grid material of full-sealed lead-acid accumulator.
3, this alloy material has good casting properties, can utilize existing equipment production, and processing performance is good.
4, use the serial enclosed non-maintenance store battery of the 6V3Ah of this alloy material assembling to 12V100Ah, its confined reaction efficient is up to 99.3%; Its corrosion rate only is 33% of a pure lead; Prove that through X ray, XPS analysis the corrosion product of this alloy is PbO
2, do not contain PbSO
4, overcome because grid surface corrosion product is PbSO
4And the early stage capacity of the battery that causes descends; It changes into time 20-22 hour from routine the pole plate of making of this alloy, shortens to 17-18 hour, has shortened the production cycle, has saved manpower and materials; In addition, its high rate discharge reaches 34 fens, and the overdischarge characteristic is to reach 64.00% of capacity; The characteristic of overcharging reaches 100.66% of capacity; Dark cycle life reaches more than 300 times; Its storge quality is also up to more than 66%.Every index all reaches and has surpassed the technical requirements of the SBA2101-88 of Japanese Industrial Standards defined.
Alloy material of the present invention can have multiple embodiments as:
Embodiment 1:
Adopt the Pb-0.3%Sb-0.04%Na-0.05%Se alloy, under 490 ℃ of-520 ℃ of temperature, melt cast panel;
