Problems solved by technology

[0004] The object of the present invention is to provide a release agent for battery grids and a preparation method thereof. By adjusting the formulation of the release agent, the content of pure water, bone glue, polyvinyl alcohol, cork powder, aluminum hydroxide, and phosphoric acid is adjusted. The technological process prepares the release agent, stirs it evenly, and completes it after cooling for use, which solves the problem of poor adhesion of the existing release agent, short use time, high cost of use, labor and material resources, and poor preparation of the release agent. Pores, cracks, and uneven weight are likely to occur during grid casting

Abstract

The invention discloses a mold release agent for a battery plate grid and a preparation method thereof, and relates to the technical field of mold release agent preparation. The mold release agent isprepared from the following raw materials in parts by weight: 95 to 105 parts of pure water, 0.5 to 0.8 part of bone glue, 0.1 to 0.3 part of polyvinyl alcohol, 1.9 to 2.3 parts of cork powder, 0.1 to0.3 part of aluminum hydroxide, and 0.1 to 0.3 part of phosphoric acid. The preparation method comprises the steps of stirring the pure water, the bone glue, the polyvinyl alcohol, the aluminum hydroxide and the phosphoric acid, heating to 100 DEG C, completely dissolving, cooling for 30 minutes, heating until boiling, adding the cork powder, stirring uniformly, and cooling for standby use. According to the mold release agent for the battery plate grid and the preparation method thereof provided by the invention, through adjusting a formula of the mold release agent, adjusting the contents ofthe pure water, the bone glue, the polyvinyl alcohol, the cork powder, the aluminum hydroxide and the phosphoric acid, and preparing the mold release agent according to a technological process, the mold release agent is good in adhesiveness and long in service life; the plate grid is uniform in weight and smooth and level in surface; and the negative phenomena of rib burning, airhole generating and crack forming are effectively reduced, so that the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of release agent preparation, in particular to a release agent for battery grids and a preparation method thereof. Background technique [0002] At present, more than 80% of the grids used in domestic lead-acid batteries are gravity casted. The lead-based alloy is melted and cast into the mold of the grid. During casting, the release agent is an indispensable auxiliary product. It makes it easier for the grid to come out of the mold; the mold is made of metal, and the heat dissipation is fast, and the groove in the cavity of the mold is relatively narrow and shallow, making it difficult for the molten alloy liquid to fill the mold. The mold agent can ensure the fluidity of the alloy and the forming rate of the cast grid. [0003] The quality of the release agent directly affects the quality of the grid casting. The poor configuration of the release agent not only affects the release efficiency but also affe...
