Abstract
A grid plate for lead-acid accumulator is made up of Ca (0.08-0.14%), Al (0.015-0.03%), Bi (0.09-0.25%), Ag (0.1-0.2%), Ni (0.01-0.03%), Cu (0.1-0.25%), Na (0.04-0.08%), Sn (1-2%) and lead (rest) through smelting at 1150 deg.c and casting at 500-510 deg.C. Its advantages are high strength and anticorrosion performance and long service life.
Description
The present invention relates to a kind of battery grid.Specifically, the present invention relates to a kind of lead-acid accumulator grid alloy material and preparation method thereof.
Lead acid accumulator has more than 100 year history, and wherein grid material is developed a kind of lead-calcium alloy in recent years except traditional Pb-Sb alloy: the Pb-Ca-Sn-Al alloy is widely used in sealed lead-acid accumulator free from maintenance.Chinese patent 91100479.3 has disclosed this alloy.It consists of: lead: 96.12-92.76%, and copper: 0.3-0.5%, calcium: 0.05-0.2%, aluminium: 0.03-0.04%, tin: 1.5-2.5%, silver: 2-4%.This alloy has overcome the shortcoming of original lead-antimony alloy corrosion-resistant, has prolonged the life-span of storage battery relatively.Yet the mechanical strength of this alloy is lower, and creep-resistant property is poor, and the screen of making often deforms.Its anodal screen surface corrosion product is PbSO4 in addition, easily causes the early stage capacity of storage battery to descend.
The purpose of this invention is to provide a kind of multielement accumulated plate bar alloy material,, improve the grid quality, prolong the grid life-span to improve the intensity and the corrosion resistance of Pb-Ca-Al ashbury metal in the past.
Purpose of the present invention realizes by following proposal: alloying component and ratio are: calcium: 0.08-0.14%, aluminium: 0.015-0.03%, bismuth: 0.09-0.25%, silver: 0.1-0.2%, nickel: 0.01-0.03%, copper: 0.1-0.25%, sodium: 0.04-0.08%, tin: 1.0-2.0%, all the other are plumbous.It is pure that above raw material is all got analysis.
Aluminium and calcium is placed in the lead pan smelts, in 670 ℃ of fusings, insulation; Above-mentioned other materials is put in another crucible, be heated to 1150 ℃ of fusings, stir,, put, take out, put into aforementioned aluminium calcium lead and go, be heated to 650 ℃, stir, cast grid in 490-530 ℃ to the solid shape of room temperature to going in the ingot mould.
With the positive and negative electrode grid that alloy of the present invention is made, its corrosion product detects through X ray, " XPS " and proves PbO2, does not contain PbSO4, thereby has overcome the shortcoming that the early stage capacity of storage battery descends.Its satisfactory mechanical property: hardness number HB16.5kg/cm
2, db6.15kg/cm
2And good casting properties and electric conductivity are arranged.Is common power lead acid battery 5-6 times with it as 100% dark cycle life of the 12v-12AH electric vehicle power type sealed lead acid storage battery of plate railings of anode and cathode assembling.
