Abstract
The invention relates to a lead-calcium polar plate for a storage battery, and a collecting bar welding rod. The collecting bar welding rod is characterized by being prepared from the components in percentage by weight: 3.5-4.5 percent of antimony, 0.1-0.4 percent of tin, 0.02-0.08 percent of arsenic and the balance being lead. With the adoption of the collecting bar welding rod, the phenomena of faulty welding and false welding are not easy to occur, the welding quality is good, and the service life of the storage battery is relatively long.
Description
Technical field
The present invention relates to storage battery production technical field, specifically a kind of accumulator cell lead calcium pole plate and the bus-bar welding rod that freezes.
Background technology
Storage battery is in illumination, automobile, electric motor car, there is application comparatively widely in the fields such as motorcycle, it mainly comprises battery case, battery cover and be located at a plurality of utmost point group in battery case, utmost point group comprises that multi-disc is mutually just overlapping, negative plate and for separating the demarcation strip of positive/negative plate, just, negative plate top is provided with lug, the lug of same polarity is welded to connect by bus-bar, and the grid alloy that forms positive/negative plate has multiple, the grid of common opening accumulator plate is generally cast with lead-antimony alloy, the grid of maintenance free cell pole plate is generally with low antimony alloy or lead-calcium alloy casting, the positive/negative plate being formed by lead-calcium alloy slab lattice and bus-bar welding are used slicker solder welding rod to freeze conventionally, while using this type of welding rod to freeze, terne metal easily and other alloy surface adhesion, in the process of freezing, welding rod easily and bus-bar adhesion, operation rhythm is easily interrupted, in addition storage battery specification is more, plate ear thickness width difference is large, more be prone to rosin joint, the phenomenon of dry joint, welding quality causes anxiety, affect the useful life of storage battery.
Summary of the invention
Technical problem to be solved by this invention is: a kind of welding quality good accumulator cell lead calcium pole plate and the bus-bar welding rod that freezes is provided.
The technical solution adopted in the present invention is: a kind of accumulator cell lead calcium pole plate and the bus-bar welding rod that freezes is provided, and described welding rod is containing consisting of the following composition (by weight): antimony 3.5 ~ 4.5%, and tin 0.1 ~ 0.4%, arsenic 0.02 ~ 0.08%, all the other be lead.
As preferably, described welding rod is containing consisting of the following composition (by weight): antimony 3.9 ~ 4.2%, and tin 0.2 ~ 0.3%, arsenic 0.03 ~ 0.06%, all the other be lead.
Accumulator cell lead calcium pole plate of the present invention and bus-bar freeze welding rod owing to containing lead and antimony alloy, this lead-antimony alloy eutectic is more, in welding process, energy and plumbous calcium pole plate and lug effectively merge, reduce rosin joint, the situation of dry joint occurs, and appropriate tin is a kind of nucleator, poor fluidity while avoiding welding, easily produce pore, crackle, arsenic can improve the problem of bus-bar corrosion, when the welding rod that freezes that employing contains above composition welds bus-bar, ears of pole plate dry joint rate has dropped to 0.0086% by 0.74%, and bus-bar corrosion rate is slow, obviously promote the quality of welding, service lifetime of accumulator increases to some extent.
