Description
The invention belongs to a kind of lead 2-base alloy material, especially a kind of alloy material that is used for closed lead acid accumulator positive and negative electrode grid.
In recent years, lead acid cell develops to the enclosed non-maintenance direction, so to the key part in the store battery: the alloy material of grid has carried out a large amount of research.The Pb-Ca-Sn-Al alloy that extensively adopts is both at home and abroad made grid at present, the assembling closed lead acid accumulator.Yet this alloy exists three major defects, that is: the physical strength of alloy is lower, can not satisfy the requirement of large-scale store battery, because the anode plate grid surface that makes of this alloy generates PbSO
4Cause the distortion of grid to expand, easily cause the short circuit of inside battery: because the PbSO on anode plate grid surface
4Cause the early stage capacity of battery to descend.
The purpose of this invention is to provide a kind of application Na, Li, elements such as Sr further strengthen the Pb-Ca alloy, and application Ag, Se, the closed lead acid accumulator positive and negative electrode alloy material for slab lattice that elements such as S go bad and handle material is to overcome weak point of the prior art.
The object of the present invention is achieved like this.
Positive-negative electrode plate grid allog material for sealed lead-acid battery is by Pb, Ca and additive Se, and Sr, Sn, Al forms.Wherein by weight: (1) Ca0.01-0.14%; (2) every single element 0.01-1% that plants in the additive; All the other are Pb.
Positive-negative electrode plate grid allog material for sealed lead-acid battery is by Pb, Ca and addition of C u, and Bi, Sr forms.Wherein by weight: (1) Ca0.01-0.14%; (2) every single element 0.01-1% that plants in the additive; All the other are Pb.
The alloy composition of positive-negative electrode plate grid allog material for sealed lead-acid battery (weight) can also be:
1, Ca0.1%, Bi0.12%, Li0.01%, S0.05%, all the other are Pb.
2, Ca0.09%, Sn0.2%, Al0.02%, Bi0.1%, Na0.02%, all the other are Pb.
3, Ag0.02%, Na0.01%, Ca0.08%, Sn0.2%, all the other are Pb.
The invention described above alloy 480-500 ℃ of fusing down, is stirred and casts grid, and die temperature is controlled at 140-160 ℃.3 days smear plate of ageing treatment changed into through 17-19 hour, but just assembling accumulator.
Alloy material of the present invention is adding Na, after Li and the Sr, lead-calcium alloy is further strengthened, improved the mechanical property of Pb-Ca alloy material, adopted Ag, Se and S are to the material processing of going bad, improved the corrosion resistance nature of alloy material, alloying element cu simultaneously, the adding of Bi and Al can change the condition of surface of alloy, improve the surface activation energy of alloy, suppressed the generation of PbSO4.
The present invention also can be with Sn, and Bi and Na make master alloy earlier, joins in the Pb-Ca-Al alloy for preparing to go again, because Sn, the alloy disperse of Bi has improved surperficial intensity of activation in alloy surface, make PbO2 keep getting off, be not transformed into PbSO4, and Na strengthens to alloy further again.
Alloy material of the present invention has good mechanical property, its HB=1.4504 * 10
-2MPa, 6b=5.0176 * 10
-3MPa, and has a superior corrosion resistance energy, high H separates out overpotential, and the anodic corrosion product of making anode plate grid of this material is PbO2, because this resistance alloys is little, the pole plate time of changing into can shorten 3-4 hour, simultaneously, the manufacturing process of this alloy is simple, just can manufacture on existing common production unit, make the closed lead acid accumulator that grid is assembled with this alloy material, its every technical indicator can reach the requirement of Japanese Industrial Standards.
The present invention can have following embodiment
(1) Ca0.08%, Se0.03%, Sr0.0 2%, Sn0.3%. Al0.0 2%, all the other Pb.
(2) Ca0.1%, Cu0.05%, Bi0.14%, Sr0.02%, all the other Pb.
