Abstract

The invention discloses an aluminum shell battery shell decontamination and rust removing agent and a preparation method and application thereof. By mass, 5%-10% of pine perfume, 5%-10% of dimethyl carbonate, 5%-20% of sodium hydroxide, 10%-20% of water and the balance aluminum degreasing cleaning agent are used for jointly preparing the aluminum shell battery shell decontamination and rust removing agent, the finished product is stable in ingredient, the decontamination and rust removing effect is good, blots and electrolyte crystals of a battery shell can be quickly and easily removed, the problems about pollution or corrosion caused by electrolyte sputtering on the aluminum shell battery shell are effectively solved, the cleaning and decontamination effects are good, and the material cost is low.

Description

technical field [0001] The invention relates to the technical field of preparation of decontamination and derusting agents, in particular to a decontamination and derusting agent for aluminum shell battery casings, a preparation method and application thereof. Background technique [0002] Cleaning the surface of the battery shell has always been a major problem in the battery cell industry, especially for power batteries with an aluminum shell as the shell. The surface of the shell is a PA layer. During liquid injection and replenishment, the electrolyte After splashing on the surface of the battery cover, electrode group, explosion-proof valve, etc. for a long time, the electrolyte and its dirt have a certain affinity with the shell of the PA layer, and can be strongly adhered to the outer surface of the aluminum shell battery. Effective cleaning will cause the surface of the shell to corrode and become more polluted, which will not only affect the appearance of the batter...
