Mold releasing agent and preparation method thereof

Abstract

The invention discloses a mold releasing agent and a preparation method thereof. The mold releasing agent comprises the following raw materials by weight: 500 g of pure water, 6-9 g of adhesive, 1-3 g of stabilizing agent, and 15-35 g of cork powder, wherein the adhesive is bone glue; the stabilizing agent is polyvinyl alcohol; and the cork powder is mixed powder of cork powder of 200 mesh and cork powder of 600 mesh. The preparation method of preparing the mold releasing agent comprises the following steps: (1) pouring of a backing material: the pure water is poured in an aluminum pot; (2) adding of the adhesive and the stabilizing agent, heating and stirring: the adhesive and the stabilizing agent are added in the aluminum pot; the aluminum pot is heated to a boiling point; and the mixing is performed during heating; (3) adding of the cork powder: the cork powder is added in the aluminum pot, and the mixture is cooled to the room temperature; and (4) storage. The process is simple and the cost is low; the mold releasing agent has the advantages of easy coating, good adhesiveness, high-temperature resistance, high-pressure resistance and smooth exhaust; the number of mold spraying times in unit time is decreased; the production efficiency and the product quality are improved; and the economic benefit of enterprises is enhanced.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and in particular relates to a hot casting mold release agent and a preparation method thereof. Background technique [0002] The grid is the main component of the lead-acid battery plate. The quality of the grid directly affects the overall performance of the lead-acid battery. However, the grid is affected by the quality of the release agent during the casting process, and the product often produces Defects such as seven holes, cracks, uneven thickness, etc. At present, the factories of lead-acid batteries generally use 200 mesh or 400 mesh cork powder, and some other substances such as sodium silicate are added. And the particle size is large, which affects the quality of the release agent and reduces the quality of the grid, thereby affecting the use of the storage battery. Moreover, the formulation process of the previous release agent is too complicated and the cost is high, wh...
