Abstract

The invention provides high-performance scaling powder for a lead-acid storage battery and a preparing method of the high-performance scaling powder. The high-performance scaling powder for the lead-acid storage battery comprises following raw materials including chlorogenic acid, 1-dodecyl-3-methylimidazole nitrate, quadri (cetane sulfenyl) tetrathiafulvalene, a silane coupling agent, epoxy modified acrylic resin, a surface active agent, 2-phenylethylamine, ethanol and water. The preparing method of the high-performance scaling powder for the lead-acid storage battery comprises the followingsteps that firstly, the raw materials are weighed; secondly, the quadri (cetane sulfenyl) tetrathiafulvalene is scattered in the silane coupling agent, and a mixture A is obtained; thirdly, other rawmaterials except 2,4,6(trimethylbenzoyl) diphenylphosphine oxide are mixed with the mixture A; and fourthly, before usage, the 2,4,6(trimethylbenzoyl) diphenylphosphine oxide is mixed, and then the high-performance scaling powder is obtained. The provided scaling powder is good in weld aid effect, and welded base metal is free of corrosion; and after usage, the welding spot electric conductivity is high, and firmness is good.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a high-performance flux for lead-acid batteries and a preparation method thereof. Background technique [0002] Lead-acid batteries are widely used in transportation, communication, electric power and other fields due to their good reversibility, stable voltage characteristics, long service life, wide application range, abundant raw materials and low cost. In order to ensure the smooth progress of the lead-acid battery welding process, solder resist is usually used to assist the welding operation. It is required that the flux can remove the oxide film on the surface of the base material to be welded, and can also reduce the surface tension of the molten solder and improve the solder and the firmness of the base metal being welded. However, the overall performance of the currently used soldering flux is not ideal, and the shortcomings are mainly as follows: 1) the ele...
