Problems solved by technology

[0004] The preparation of the release agent directly affects the output and quality of the grid casting. The main reasons are: First, because the grid is prone to produce pores, hidden cracks, burrs, broken ribs and paste ribs during casting, and it is coated and filled into plates to manufacture The service performance of the battery will be affected after the battery, and the service life of the lead-acid battery will be shortened. It is easy to be not resistant to high temperature and burn off, which causes the operator to stop frequently to repair the mold and re-spray the mold, resulting in a waste of time and manpower, and increases the production cost

Abstract

The invention discloses a release agent for casting a storage battery grid and a preparation method thereof. The release agent comprises the following raw materials of, in parts by mass, 100 parts ofdeionized water, 1.21-1.32 parts of cork powder, 1.05-1.18 parts of bone glue, 0.35-0.37 part of polyvinyl alcohol, and 0.16-0.26 part of nano zirconium oxide sol. According to the release agent for casting the storage battery grid, the formula amounts of the cork powder, the bone glue and the polyvinyl alcohol are adjusted, and meanwhile, a high-temperature-resistant nano zirconium oxide sol is added, so that the problems that an existing release agent is not resistant to high temperature, poor in adhesion, short in service time and large in weight fluctuation are solved, the phenomenon thatair holes are easily formed in the grid is improved, the single-machine and single-shift yield of the grid and the quality of the grid are improved, the production cost is reduced, and the productionefficiency is improved.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a release agent for battery grid casting and a preparation method thereof. Background technique [0002] The grid is an important part of the lead-acid battery plate. Its role in the lead-acid battery is mainly to support the active material, to be the carrier of the active material, to collect and conduct current, to distribute the current evenly on the active material, and to improve the utilization of the active material. Rate. Therefore, the quality of the grid directly affects the overall performance of the lead-acid battery. [0003] At present, the grids used in domestic lead-acid batteries are basically produced by gravity casting. The alloy lead is melted by the lead melting furnace and then transported to the lead spoon through the lead pipe, and cast into the grid mold cavity through the lead spoon. Before casting, the main functions of spraying release ag...
