Abstract

The invention belongs to the preparation method of ammonium salt lead storage battery electrolyte. The preparation method comprises the following steps: stirring mother liquor under room temperature, and adding EDTA, an anti-ageing agent, 2-mercapto benzimidazole diallyl sulfide, an antioxidant, 2,6-butylated hydroxytoluene, tripotassium phosphate and sodium salt in sequence to prepare a mixed liquor; stirring the mixed liquor until the temperature reaches 40DEG C, and leaving to stand for 30-40 minutes; adding a buffer solution into the mixed liquor for stirring for 10-15 minutes, and leaving to stand for 20-25 minutes; adding pure water into the mixed liquor to dilute until the solution density reaches 1.1-1.3g/cm<3>, stirring for 30 minutes, and leaving to stand for 12 hours to obtain a semi-finished product; feeding the semi-finished product into crystallization equipment to obtain ammonium salt; adding pure water into the ammonium salt to dilute the ammonium salt. The preparation method has the advantages of being simple and reasonable in technological process, effectively improving the cleaning and production level of enterprises, effectively improving the safety performance of lead storage batteries and prolonging the service life of the lead storage batteries.

Description

technical field [0001] The invention belongs to the technical field of storage battery electrolyte, and in particular relates to a preparation method of ammonium salt lead storage battery electrolyte.
