Abstract
The present invention relates to a grid alloy for accumulator and its production process, and said grid alloy uses several elements of lead, copper, tin, aluminium, calcium and silver, etc. and can be made into accumulator grid alloy by using simple method.
Description
The present invention relates to manufacture the type material of all kinds of lead acid accumulator plate grids, a kind of polynary, high energy, corrosion-resistant accumulator plate grid alloy and preparation method thereof.
Since the founding of New, China's battery industry uses lead antimony alloy to manufacture battery grid always.Because lead antimony alloy hardness, intensity are all bigger, the preparation simple procedure, liquid fluidity is good, helps lead plaster and adheres to, so lead antimony alloy is used as the main alloy material of making battery grid and extensively adopts always.But lead antimony alloy also has some shortcomings in essence, S during as battery charge
bCan on spongy negative electrode, separate out from anodic stripping, form local small battery, produce self-discharge.In addition, S
bSame P
bThe overpotential of hydrogen of comparing is little, and electrolytic solution is decomposed easily.Therefore must often moisturizing in the use of battery.Produce deleterious S from negative electrode when overcharging
bH
3Simultaneously, lead antimony alloy accumulator anode corrosion-resistant, it is serious that these make that the lead antimony alloy store battery has a self-discharge, maintenance trouble, the defective that work-ing life is short.
In recent years, make that for the new demand that reduces maintenance capacity and propose the corrosion-resistant problem of anode plate grid of lead antimony alloy is more outstanding along with the improvement of battery separator with for improving slim utmost point grid that the battery specific energy adopts and battery industry, and become the principal element that influences the life of storage battery.Therefore, the battery research worker of many countries is endeavouring to seek the better template grid material of a kind of performance to reach the purpose of extending battery life.Now existing lead-calcium alloy, lead-calcium-tin alloy etc.These new alloys have all improved accumulator quality to a certain extent, have improved the performance of store battery.But, prolonging store battery on work-ing life, effect is not quite obvious.
The purpose of this invention is to provide a kind of multielement accumulator plate grid alloy and making method.Make store battery compare and can save material more than 10% with the lead antimony alloy store battery, and gassing is few, self-discharge is light, keep in repair easy, but and prolongs life 3-4 doubly.
Multielement battery grid of the present invention has fully phased out antimony and has made stiffening agent under the prerequisite that does not reduce grid intensity, and has realized that gasification is few, and water loss is slow, and self-discharge is slight, the purpose of long service life.This alloy is made up of lead, copper, aluminium, silver, calcium, the hexa-atomic element of tin, and lead element adopts 99.994% electrolytic lead to replace the lead bullion that uses in traditional lead antimony alloy.
Each set of dispense ratio of described multielement accumulator plate grid alloy:
Alloying element requires plumbous 99.994% 96.12～92.76% bronze medal, 99.5% 0.3～0.5% calcium of standard proportional (weight ratio) 1# 99% 0.05～0.2% aluminium 99.5% 0.03～0.04% tin 99.5% 1.5～2.5% silver medal 99.7% 2～4%
The process for making of described multielement accumulator plate grid alloy is as follows:
More than six kinds of raw materials weigh by upper limit (UL), separated deposit, these several elements are made master alloy in proportion in crucible.In making processes, to add a cover wood charcoal powder with anti-oxidation.And add calcium at 500 ℃, 600 ℃ add silver, and 660 ℃ add aluminium, and 700 ℃ add copper, stir and pour in the ingot mould.
Then the lead pig of cleaning, drying is put into the crucible of preheating, added charcoal after the fusing and cover, the master alloy nearly 600 ℃ time that heats up stirs, and sampling analysis outgases with ammonium chloride when temperature is reduced to 500 ℃, pours in the ingot mould then.
When needs are manufactured grid, dissolve the casting grid with above-described alloy by processing requirement and get final product.
Since 84 years, contrasted through test of many times, be used for the automobile storage battery pole plate, under the prerequisite of guaranteed capacity, pole plate reduces to 1.8m/m by 2.4m/m and saves material about 20%, prolong 3～4 times work-ing life, gassing reduces, and the moisturizing phase prolongs 10 times, self-discharge is slight, and erosion resistance improves 3～4 times.
Be example in detail to make the miner light storage battery grid below:
One, get the raw materials ready:
1, at first electrolytic lead, copper, aluminium, calcium, tin, silver are made master alloy in ratio separately, be made into final alloy again, be cast into alloy pig according to producing needs.
2, cast the shot of 25～30m/m with the electrolytic lead of lead tolerance 99.994%, wear into 120 order lead powder with ball mill then,, qualified lead powder is poured in the bucket deposited then through the chemical examination degree of oxidation of lead powder, standby.
Two, make positive/negative plate:
1, alloy pig is put into crucible melting, when temperature reaches 525～550 ℃ alloy liquid poured in the anode plate grid mould and water into anode plate grid, anodal glass fiber pipe box on anode plate grid stamen post, injecting lead powder in the pipe, seal up collet, with the lead powder that be stained with clear water flush away outside, oven dry back etc. are to be changed.
2, alloy liquid is poured in the negative electrode grid mould, watered into negative electrode grid.In lead powder, add relevant additive (carbon black, barium sulfate, humic acids etc.), adding paste mixing machine with proportion 1.05 dilute sulphuric acids stirs, treat cream and become the back lead plaster to be evenly coated on the negative pole plate with special tool, send into 4 normal atmosphere of steamer after the leveling took out in 40 minutes, be placed on then on the cool horse, oven dry etc. are to be changed.
Three, pole plate changes into:
Positive/negative plate is put into electrolytic bath by certain arrangement, positive/negative plate is welded in respectively on the electrified wire, carry out constant current energising 40～50 hours.Take out then with clear water flush away surface acid solution, go into the drying shed oven dry after cool 2 hours.Again pole plate is put into punch press and be washed into monolithic, use when putting into case for assembling.
Four, assembling:
Two of negative plates are welded into one, positive plate is contained in the middle of two negative plates, accompany glass yarn and plastic septum between the pole plate, pack in the battery jar,, mouth is obturaged, check behind the natural airing with glue by last connecting strip by the positive and negative electrode sign.
