Abstract

The invention belongs to the technical field of storage battery manufacturing, and specifically relates to a lead acid storage battery electrode plate acid spraying and a preparation method thereof. The electrode plate acid spraying comprises positive electrode plate acid spraying and negative electrode plate acid spraying, wherein the positive electrode plate acid spraying is composed of the following raw materials in parts by weight: 0.3 to 0.8 part of sodium carboxymethyl cellulose, 0.5 to 1 part of polyethylene glycol, 0.5 to 2 parts of sodium sulfate, 0.1 to 0.5 part of stannous sulfate, 3.2 to 7.7 parts of sulfuric acid, and 88 to 94.9 parts of water; and the negative electrode plate acid spraying is composed of the following raw materials in parts by weight: 0.3 to 0.8 part of sodium carboxymethyl cellulose, 0.5 to 1 part of polyethylene glycol, 0.5 to 2 parts of sodium sulfate, 0.1 to 0.5 part of stannous sulfate, 7.7 to 14.7 parts of sulfuric acid, and 81 to 90.4 parts of water. The storage battery electrode plate acid spraying can control the acid spraying density, and at the same time prominently improves the storage battery properties of recharging, over-discharging, low-temperature capacity, and service life.

Description

technical field

[0001] The invention belongs to the technical field of storage battery manufacturing, and in particular relates to a lead-acid storage battery polar plate soaking acid and a preparation method thereof. Background technique

[0002] In the production process of the lead-acid battery plate, after the plate is coated, the plate surface needs to be soaked in acid and rolled. Adding additives in the acid bath can increase the amount of lead paste on the plate, so that the strength of the lead paste on the surface of the plate is improved, and the surface of the plate is The content of lead sulfate is low, the generation of lead sulfate is inhibited during the battery discharge process, and the conductivity of the lead paste on the surface of the plate is improved, so as to improve the overall performance of the battery.

[0003] Coated board dipping acid production line (see figure 1 ): 1-1 is the plate coating machine and lead paste storage bucket; 1-2 is the co...
