Abstract

The invention belongs to the technical field of storage batteries, particularly relates to scaling powder for a lead-acid storage battery and a preparation method thereof. The problems that existing scaling powder has a severe destructive effect on clapboards, severe corrosion effect on welded base materials, welding fluxes and cast-welding dies, severe harm to human bodies, and residues after welding influence performances of the lead-acid storage battery are solved. The scaling powder of the lead-acid storage battery comprises N-butyl-N-Methyl pyrrolidine dodecyl sulfate, sodium lignin sulfonate, borax, muriate, vaseline, N-Methyl pyrrolidone, alginate sodium, ethyl alcohol, isopropanol and deionized water. The scaling powder is safe and environment-friendly, and enables a busbar and anelectrode lug to be connected more tightly and artistically, effectively protects the welded base materials and the cast-welding dies; cycle life of the battery is prolonged; the preparation method issimple to operate, the required condition is mild; and the method facilitates industrial production and is worthy of popularizing.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to a flux for lead-acid accumulators and a preparation method. Background technique [0002] In storage batteries, lead-acid batteries have the advantages of mature technology, cheap price, good charging and discharging performance, and safe use. As the most important stable power supply and DC power supply, they are widely used in aviation, railways, automobiles, ships, communications, and finance In various industries such as military and national defense, it has become an indispensable energy product in social production and human life. [0003] Lead-acid batteries are assembled in units of pole groups. The pole group is composed of multiple positive and negative plates and separators. In each pole group, the tabs of the same pole are cast and welded with the bus bar to form the positive bus bar and the negative bus bar. Row. During the casting process, flux must be used. ...
