Abstract

The invention discloses a positive and negative plate additive of a lead-acid accumulator and a preparation method thereof. The positive and negative plate additive of the lead-acid accumulator comprises the following raw materials in part by weight: 120 to 130 parts of deionized water, , 4 to 10 parts of gas-phase nanometer silicon dioxide and 10 to 25 parts of other additives, wherein when a positive plate is prepared, other additives mainly comprise high-purity graphite, sodium silicate and polytetrafluoroethylene; and when a negative plate is prepared, other additives mainly comprise sodium ligninsulphur, high-purity humic acid, barium sulphate, acetylene carbon black and barium stearate. The additive of the invention is emulsion, a high-speed shearing way is adopted in the preparation method, and the additive has high dispersibility, and is more uniformly mixed with each component in the additive after being mixed and stirred with lead powder, so that the additive can not only improve and enhance the technical performance of the accumulator, but also prolong the service life of the accumulator.

Description

technical field [0001] The invention relates to a battery positive and negative plate additive and a preparation method thereof, in particular to a lead-acid battery positive and negative plate additive and a preparation method thereof. Background technique [0002] Additives are an important component of lead-acid batteries, which have an important impact on the performance of batteries. Additives added to lead-acid batteries are generally divided into: plate additives and electrolyte additives. Plate additives are added during paste mixing. Speaking, the main function is anti-shrinkage, also known as expansion agent; for the positive plate, it mainly increases the strength of the plate, prevents softening, falling off and increases conductivity. [0003] At present, in the production of lead-acid battery plates, the method of adding powder additives is commonly used. After mixing the dry raw materials and adding water, after stirring and mixing, there is a low uniformity, ...
