Abstract

The invention discloses a deep cycle battery lead paste preparation method with a characteristic of easy 4BS generation, and belongs to the technical field of lead storage battery production. The preparation method comprises: (1) carrying out dry mixing on lead powder and additives excluding diantimony trioxide and stannous sulfate, adding water, carrying out wet mixing, adding sulfuric acid accounting for more than 80% of the total acid amount, carrying out a stirring reaction, and controlling the reaction temperature at 65-85 DEG C to obtain a first acid mixing lead paste; and (2) adding diantimony trioxide and stannous sulfate to the remaining sulfuric acid to obtain a sulfuric acid mixed solution, mixing the sulfuric acid mixed solution into the first acid mixing lead paste, carrying out a stirring reaction, and cooling to achieve a temperature of less than 45 DEG C to obtain the deep cycle battery lead paste. According to the present invention, the acid adding is performed twice in the method, and the 4BS-inhibiting components such as diantimony trioxide and stannous sulfate are added at the late stage, such that the power battery lead paste formula is not affected, and a certain amount of the 4BS can be effectively obtained.

Description

technical field [0001] The invention relates to the technical field of lead storage battery production, in particular to a preparation method for deep-cycle battery lead paste which is beneficial to the generation of 4BS. Background technique [0002] In the production process of lead-acid batteries, mixing paste is a key process of the battery process, and its quality directly affects the performance of the battery, especially the life of the battery and the initial performance of the battery, and the initial performance and life of the battery are directly related to the lead-acid battery. Consumer needs. [0003] In order to further improve the life of the battery, a common practice is to form a certain amount of tetrabasic lead sulfate (4BS) through high temperature during paste mixing / curing, thereby strengthening the skeleton of the positive active material to improve the life of the battery. Tetrabasic lead sulfate (4BS) has the advantages of large crystal size, tigh...
