Description
Technical field
The invention belongs to the preparing technical field of plumbous band.Relate in particular to the preparation method that a kind of battery plate is with lead.
Background technology
Positive/negative plate is the vitals of lead acid cell.As the carrier of active goods and materials and electric current, pole plate is in use normal because serious corrosion occurs in anodic polarization, thereby has greatly affected the life-span of store battery.Once be the method that more generally adopts by adding alloying element with the corrosion resistance that improves the lead 2-base alloy pole plate, although this method can be alleviated the corrosion of pole plate to a certain extent, but the interpolation of element can cause the pole plate processing difficulties and can produce battery when charging hydrogen separating out and waiting impact to produce and the problem of product performance, and the cycle life of store battery is ideal not bery also.
Adopting the method for Grain Boundary Character distribution optimization is to increase considerably the strong special grain boundary of solidity to corrosion in lead alloy, with the remarkable corrosion resistance that improves pole plate, prolongs the lead acid cell purpose in work-ing life thereby reach.The method of anticorrosive capacity of grid plate for lead-acid battery " improve " (CN200510021837.5) patented technology thought: the method for " carrying out at least twice cold rolling being lower than under the used lead 2-base alloy material recrystallization temperature; and each rolling direction of adjacent time is mutually vertical; after carrying out anneal in each rolling rearmounted annealing furnace; carry out again next time cold rolling; so be repeated to the total deformation that the accumulative total deflection reaches slab lattice thickness and require ", " corrosion resistance and the service lifetime of accumulator that improves grid alloy played an important role ".Yet it is impossible that the rolling direction of adjacent passage is vertically finished the rolling of the long plumbous band of hundreds of rice mutually; Too much anneal makes complex manufacturing, annealing temperature is high and annealing time is longer, and in addition, the increase that often gathers way with the annealing number of times of special grain boundary proportion reduces.
Summary of the invention
The present invention is intended to overcome the prior art defective, and purpose provides the plumbous preparation method who is with of battery plate that a kind of technique is simple, with short production cycle and cost is low, and the battery plate prepared with the method is strong with the corrosion resistance nature of lead band.
For realizing above-mentioned task, the technical solution used in the present invention is: will prepare battery plate and melt with the plumbous lead alloy of being with, and continuous casting, rolling, battery plate is 0.4 ~ 1.2mm with the finished product thickness of plumbous band.
Battery plate with the finished product of plumbous band before rolling pass and battery plate be 22 ~ 44% with the rolling draft of the plumbous finished product rolling pass of being with.
Battery plate with the finished product rolling pass of plumbous band before and battery plate respectively carry out a thermal treatment after with the plumbous finished product rolling pass of being with.
Described preparation battery plate with the lead alloy chemical composition of plumbous band is: Ca is 0.04 ~ 0.1wt%, and Sn is 0.9 ~ 1.8wt%, and Al is 0.01 ~ 0.03wt%, and all the other are Pb.
Described heat treated temperature is 240 ~ 290 ℃, and soaking time is 8 ~ 365 seconds.
Owing to adopting technique scheme, the present invention adopts at battery plate and respectively carries out a thermal treatment with the plumbous finished product rolling pass of being with is forward and backward, can continuous rolling, therefore preparation technology is simple.Because thermal treatment process is to carry out at the forward and backward of finished product rolling pass of battery plate with plumbous band, battery plate during thermal treatment should be the thickness of finished product with the thickness of plumbous band and mutually near the thickness of finished product, thereby can use lower annealing temperature and shorter annealing time, therefore the present invention has not only shortened the production cycle and technique is simple, and energy consumption and production cost have been reduced.
In addition because the present invention organically combines rolling technology and the thermal treatment process of battery plate with plumbous band, make battery plate with plumbous with the special grain boundary that contains higher proportion in the finished product, thereby improved battery plate with the corrosion resistance nature of lead with finished product.
Therefore, the present invention has the advantages that production technique is simple, with short production cycle and cost is low, and prepared battery plate is strong with the corrosion resistance nature of plumbous band.
