Background technology
Existing lead electrode material mainly based on the more much higher first alloy of lead tolerance, as lead-calcium-tin alloy, plumbous calcium silver alloy, pb-ag alloy etc., not only Heavy Weight, and cost is high.
In actual applications, general R&D direction attempts improving the mechanical strength of electrode, electric conductivity and decay resistance by the ingredient components changed in lead alloy.But complicated along with alloying component, can make self chemical property advantage plumbous weakened.
Also some R&D direction attempts adopting the structural design of Laminited composite material, such as, in Chinese patent CN101092708A, disclose a kind of aluminium and lead laminar composite material, outer by aluminium core, lead or lead alloy, and the transition elements layer composition of centre, thus constitute and inner improve electric conductivity by aluminium, weight reduction and increase mechanical strength, the middle metallurgical binding being realized aluminium and lead by transition elements, skin still keeps the corrosion resistance of lead alloy and the layered composite electrode material of chemical property.Wherein, the shape of aluminium core can be aluminium sheet, aluminium bar or aluminium web plate, for the demand of Different electrodes contour structures and function.
In Chinese patent CN102627002A, disclose a kind of aluminium base lead and lead alloy composite material, concrete preparation technology, at alumina-base material Surface Machining some wire dovetail groove along its length, the alumina-base material surface galling process of dovetail groove will be processed, again alumina-base material is sent into coating equipment with plumbous or lead alloy bar and carry out coated lead or lead alloy cladding material, coated complete after to carry out increasing list processing on cladding material surface immediately and obtain the concavo-convex or sawtooth pattern of circular arc, cooling is composite finished product.Composite material obtained like this, also has and improves materials conductive performance, current efficiency and mechanical strength, reduces the advantage of deadweight.
But, this kind of aluminium base lead composite material, because aluminium is as lively as a cricket metal, the pole plate be made up of aluminium base lead composite material is be immersed in for a long time in acid in application process, and aluminium pole is not corrosion-resistant, slightly space crack on lead layer, it is inner that combination electrode is just easily infiltrated in acid, corrosion aluminium, destroy the design to the original chemical property of this combination electrode, so utilize aluminium base lead composite material to there is the hidden danger of chemical property instability as the application of polar plate of lead acid storage battery.
Summary of the invention
The object of the invention is to solve above-mentioned drawback, provide a kind of manufacture craft of grid, lightweight, good conductivity, charging rate are fast.
