Abstract

The invention relates to a releasing agent for casting of a lead-acid storage battery grid. The releasing agent is composed of, by weight, 1.5%-2% of carbohydrates, 1%-1.3% of proteins, 5%-6% of glass cement and 90%-92% of pure water. According to a preparation method, the pure water, the carbohydrates, the proteins and the glass cement are heated and evenly stirred according to the formula ratio, and the releasing agent is formed after cooling. The pure water, the carbohydrates, the proteins and the glass cement are mixed into emulsion according to a certain ratio, and the emulsion is heated, stirred and cooled to form the releasing agent. The releasing agent is sprayed on the surface of a die, and a heat insulating layer is formed between the surface of the die and casting alloy, so that molten alloy is maintained to flow well in the die, and residual gas in the die can be smoothly exhausted. Accordingly, poor casting of the grid is avoided, the dual functions of heat preservation and ventilation are achieved, and bonding of aluminum alloy and the die is prevented.

Description

technical field [0001] The invention relates to the technical field of release agents, in particular to a release agent for casting lead-acid storage battery grids. Background technique [0002] The grid is the core part of the lead-acid battery. The grid is the carrier that supports the active material, conducts current, collects the current, makes the current evenly distributed on the active material, and improves the utilization rate of the active material. Since EFB batteries have higher requirements on the quality of the grid, the quality of the grid will directly affect the overall performance of the battery. During the casting process of the grid, due to the influence of the quality of the release agent, it is often difficult to release the mold, the quality of the grid increases too fast, and the grid has cracks, pores and uneven thickness. In addition, the mold is made of metal, which can dissipate heat quickly. The groove inside the mold is relatively shallow, ma...
