Coating agent for casting lead acid battery slab lattices

Abstract

The invention discloses a coating agent for casting a lead acid battery slab lattices, which mainly comprises the following components in part by weight: 1,000+ / -20 milliliters of water, 65+ / -5 milliliters of sodium silicate, 60+ / -5 grams of cork powder, 5+ / -2 grams of kaolin and 5+ / -2 grams of aerosol. By adopting the scheme, in the coating agent, the sodium silicate is a type of glue, the cork powder is a type of heat insulating material, the added kaolin has a function of increasing the caking property and has an efficiency of enhancing heat insulation; and the aerosol can form a hydrosol after being added into aqueous solution, and the hydrosol can increase pore spaces of an adhesive layer after being sprayed on a die. Compared with the prior art, by using the coating agent to performproduction, the number of the slab lattices produced by spraying the coating agent once by the die can be 1,500 to 4,500 chunks, and the service time of the coating agent is long, so the production efficiency of the slab lattices is improved. Besides, environment pollution caused by die brushing and influences on the health of works are reduced.

Description

technical field [0001] The invention relates to the field of lead-acid battery manufacturing, in particular to a mold coating agent used for casting grids of lead-acid batteries. Background technique [0002] The grid is an important part of the lead-acid battery. The grid serves to conduct electricity and support the active material in lead-acid batteries. The structure of the grid is generally composed of a frame, horizontal ribs, vertical ribs and tabs, just like a mesh screen, and the maximum cross-sectional size of the ribs is about 1.2mm. [0003] At present, 80% of the grids in the production of lead-acid batteries are cast, which are called cast grids. [0004] Grid casting requires a casting machine and molds. Design the grid according to the requirements of the battery, and then design the required mold according to the structure of the grid. Grid design generally requires consideration of length, width, height, position of tabs, rib structure and casting formab...

AI Technical Summary

Problems solved by technology

If the exhaust of the mold is not smooth, it may cause problems such as the failure of the grid to form and the appearance of pores inside the grid.

[0008] ③The cast grid is easy to demould

It is generally hoped that not only qualified grids can be cast after spraying the mold coating agent, but also that the longer the mold coating agent is used, the better, but in fact, the existing mold coating agent can only produce 1000- 3,000 large grids, after this amount, the grid will not be easy to demould, you have to brush the mold again, spray the mold agent, the production efficiency is greatly affected, and the labor intensity increases

Moreover, when the mold is brushed, the dust is flying, which has a bad influence on the health of the workers
