Description
Technical field
The present invention relates to a kind of alloy material, in particular it relates to which a kind of be used to make lead acid accumulator plate grid
Alloy, particularly a kind of anti-corrosion grid alloy, the alloy belongs to the electrode material in Lead-acid Battery Technology field.
Background technology
Pole plate is to influence one of main devices of performances of the lead-acid battery, and its quality determines that supporting lead-acid accumulator is used
Life-span.Pole plate is made up of grid and lead plaster, and grid quality good or not depends on the physical and chemical performance of alloy used, because in alloy compositions
Each element all directly affect grid performance, how optimized alloy component to be the industry study for a long period of time task.The current industry is general
Grid is made all over using Pb-Ca-Sn-Al alloy, and the lead-calcium alloy of such a component has good intensity and electric conductivity, but
Shortcomings, that is, creep-resistant property is not enough, corrosion resisting property is not good, and this two deficiencies directly affect the use of lead-acid accumulator
Life-span.With the development of science and technology, some important equipments and energy storage device have higher to supporting lead-acid accumulator service life
Expect.In recent years, the industry carried out the alloy research for making grid extensively, although some technical schemes are quite effective, was made
The supporting lead-acid accumulator of pole plate improve service life to a certain extent, but expect still there is very big gap with user.
The content of the invention
Present invention is generally directed to the Pb-Ca-Sn-Al alloy of prior art, grid creep-resistant property and corrosion resisting property difference is made
Problem, proposes that a kind of component is reasonable, raw material is easily purchased, smelting process is simple, dedicated for making the alloy of lead acid accumulator plate grid,
The grid being made of the alloy is obviously improved creep-resistant property and corrosion resisting property.
The present invention is achieved through the following technical solutions technical goal.
The alloy of lead acid accumulator plate grid is made, it thes improvement is that it contains the following group being measured by the percentage by weight
Point：Tin 1.0~2.0%, copper 0.02~0.12%, titanium 0.05~0.10%, silver 0.002~0.05%, bismuth 0.03~0.07%, rare earth
Element 0.01~0.10%, remaining is lead.
As further improvement project, the rare earth element mainly includes cerium, the mixture of two kinds of metals of samarium.
The present invention compared with prior art, has the positive effect that：
1st, the copper newly added in component is a kind of metal metacrystal agent, is conducive to lifting alloy creep resisting ability；
2nd, the silver and titanium physical property stability newly added in component is good, is conducive to being lifted the corrosion resisting property of alloy；
3rd, the bismuth and rare earth element newly added in component can notable refining alloy tissue, the grid being made is formed the anti-of densification
Rotten layer, alloy structure refinement also helps the toughness of enhancing alloy.
Embodiment
The present invention is further illustrated below by embodiment.
The present invention is a kind of alloy proportion technical scheme on making lead acid accumulator plate grid, and embodiment is used to make
The grid of 12V100Ah lead-acid accumulators, the component that be the same as Example is not applied is measured by the percentage by weight as follows：
Not be the same as Example component proportion table
The component proportion as listed by upper table embodiment is smelted respectively is made grid, then passes through corrosion weight loss test and high-temperature floating-charge longevity
Life experiment, further to verify the technology of the present invention effect.
1st, corrosion weight loss measures examination
First, three simulation grid experimental electrodes being made by prior art slicker solder aluminium alloy are comparative example, are separately taken by this hair
Three simulation grid experimental electrodes that bright Pb-Sn-Cu-Ag rare earth alloy is made are embodiment, then under equal process conditions respectively
Make corrosion weight loss test, test result is referred to《Different-alloy simulates grid experimental electrode corrosion weight loss test data table》.Specifically
Method of testing uses constant current corrosion weight loss method, test condition：Simulation grid experimental electrode is made in two kinds of different-alloys common
It is placed in 70 DEG C of ± 2 DEG C of environment, injects 1.32g/m3Sulfuric acid, using 30mA/cm2Electric current constant-current charge 480h, then distinguish
Weigh and note down.
Different-alloy simulates grid experimental electrode corrosion weight loss test data table
It was found from the weightless test data that upper table is recorded, using slicker solder lead bronze silver rare-earth alloy of the present invention, the simulation grid being made
Experimental electrode is more weightless than the simulation grid experimental electrode that is made of Pb-Ca-Sn-Al alloy of prior art few by 35% or so.Electrode is weightless
Data are small, absolutely prove that corrosion resisting property of the present invention has a distinct increment compared with the prior art, accomplish the end in view.
2nd, high temperature accelerates float life experiment（Failure form is grid corrosion）
Prior art Pb-Ca-Sn-Al alloy and Pb-Sn-Cu-Ag rare earth alloy of the present invention are taken, the grid of different ratio is respectively prepared,
And it is assembled into each 3 12V100Ah lead-acid accumulators of comparative example, embodiment.Experiment is in 60 DEG C of ± 2 DEG C of environment, with float charge voltage
Then 2.25V/ single lattices, trickle charge 30d takes out the lead-acid accumulator of experiment, 24h~36h is placed, in 25 DEG C of ± 5 DEG C of rings
A 3h rate capacity test is carried out in border.Above process of the test converts into as a test cycle number of times, each time cycle-index
Into 1 year life-span.Above-mentioned experiment is repeated, until when the capacity of lead acid battery of experiment is less than 3h rate rated capacities 80%, then through once
Untill validation test, the cycle-index for recording each example see the table below.
Different-alloy grid cycle-index table
It was found from above-mentioned experimental data, the grid being made of prior art Pb-Ca-Sn-Al alloy is closed than Pb-Sn-Cu-Ag rare earth of the present invention
The life-span few 24~36% is filled in grid cycle-index few 24~36%, the i.e. floating charge that gold is made, and thus can prove corrosion resisting property of the present invention
There is large increase with creep-resistant property, Technology for Modern Equipment and energy storage device can be met completely long-life to lead-acid accumulator supporting
It is required that.
