Problems solved by technology

[0006] At present, the use of conventional release agents to spray-cast grids has the following disadvantages: (1) Due to poor exhaust, the temperature of lead liquid must reach 530°C to flow into the casting normally; (2) Due to poor exhaust, the grid forming rate Low, with many pores, the pass rate is about 85%; (3) Since the temperature of the lead liquid needs to reach 530°C, the lead alloy burns seriously, and the waste product lead slag reaches 2%; (4) Due to the high temperature of the lead liquid, the The electric heating tube consumes a lot of power; (5) Due to the high tempe

Example Embodiment

[0029] Example 1

[0030] The battery grid release agent of this embodiment includes the following raw materials in weight percentages: 0.7 parts of bone glue, 0.5 parts of polyethylene, 0.4 parts of diatomaceous earth, 0.2 parts of glass water, 0.4 parts of aluminum dihydrogen phosphate, and 200-300 mesh cork powder 3 parts, 3 parts of 700-800 mesh cork powder and 91.8 parts of deionized water.

[0031] For the situation where the release agent is easy to fall off, this embodiment is suitable.

Example Embodiment

[0032] Example 2

[0033] The battery grid release agent of this embodiment includes the following raw materials in weight percentage: 0.3 part of bone glue, 0.8 part of polyethylene, 0.5 part of diatomaceous earth, 0.3 part of glass water, 0.5 part of aluminum dihydrogen phosphate, 200-300 mesh cork powder 2 parts, 2 parts of 700-800 mesh cork powder and 93.6 parts of deionized water.

[0034] For the lead liquid to cool quickly and not form, this embodiment is suitable.

Example Embodiment

[0035] Example 3

[0036] The battery grid release agent of this embodiment includes the following raw materials in weight percentages: 0.6 parts of bone glue, 0.4 parts of polyethylene, 0.8 parts of diatomaceous earth, 0.2 parts of glass water, 0.4 parts of aluminum dihydrogen phosphate, 200-300 mesh cork powder 2.2 parts, 700-800 mesh cork powder 2.2 parts and deionized water 93.2 parts.

[0037] Since the release agent is easy to be compressed, this embodiment is suitable.

Abstract

The invention belongs to the field of storage battery manufacturing technology, and particularly relates to a storage battery grid mold release agent and a preparation method thereof. The storage battery grid mold release agent is prepared from the following raw materials in parts by weight: 0.3-0.7 part of bone glue, 0.4-0.8 part of polyethylene, 0.4-0.8 part of kieselguhr, 0.2-0.5 part of glass water, 0.3-0.7 part of aluminum dihydrogen phosphate, 2-4 parts of cork powder of 200-300 meshes, 2-4 parts of cork powder of 700-800 meshes, and 88.5-94.4 parts of water. The storage battery grid mold release agent is easy to bond, high-temperature-resistant and smooth to exhaust; the prepared grid has fewer pores, thus being easily formed in casting.

Description

technical field [0001] The invention belongs to the technical field of battery manufacturing, and in particular relates to a lead-acid battery grid release agent and a preparation method thereof. Background technique [0002] Gravity casting of lead-acid batteries is the main manufacturing method of grids. The related technologies are described below: [0003] Description of grid structure (see figure 1 ): A-1 is the plate lug of the grid, one upper and lower plate lug, one of which needs to be sawed off after the grid coating is cured and dried, and one is left to be welded to the bus bar, so the plate lug to be sawed is the process The needs of the manufacturing process are called process lugs; A-2 is the frame of the grid; A-3 is the inner rib, which is the horizontal and vertical ribs of the inner frame of the grid. [0004] Instructions for grid casting slab molds (see figure 2 ): The lugs, frames, and ribs of the grid are grooved on two flat plates. The grooves on ...
