Technical field
The present invention relates to a kind of releasing agent, in particular for the releasing agent of battery grid casting.
Background technology
Grid is the chief component parts of polar plate of lead acid storage battery, draws in the net and casts two kinds, and the effect of grid in battery is mainly to support active material, the carrier that serves as active material, conduction collects electric current, makes balanced current distribution on active material, to improve the utilization rate of active material.Therefore, the quality of grid quality directly affects the overall performance of battery.Take the casting battery grid as example, its technological process of production is as follows: the alloy preparation → fusing → plate grid die preheating → jet mould → smooth → inspection → age-hardening of casting → prune.
Because grid is affected by the releasing agent cause for quality when casting, often there are the defectives such as pore, crackle, uneven thickness in product, because mould is that metal is made, therefore there are the characteristics of rapid heat dissipation, add the dies cavity groove narrow shallow, make the aluminium alloy under the melting pan state be difficult to be full of mould.Ratio of briquetting for the grid that guarantees to cast must spray releasing agent between die surface and cast alloys.Releasing agent generally is sprayed on dies cavity, and main insulation, heat insulation, lubricated guarantees that aluminium alloy is full of the effect of mould, plays corrective action to the thickness evenness of grid simultaneously.At present, the releasing agent that uses in the storage battery factory is generally formulated by cork powder, sodium metasilicate and water, and this releasing agent moulding is poor, be not durable, and easily causes unstable product quality, and production efficiency is low.
Summary of the invention
Problem to be solved by this invention just is to provide a kind of grid mould release agent, can effectively reduce the phenomenons such as pore, crackle of grid, can reduce the jet mould number of times in the unit interval simultaneously, enhances productivity, Improving The Quality of Products.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of grid mould release agent comprises that following component and each component mass percent are as follows:
Further, the each component mass percent is as follows:
Further, the each component mass percent is as follows:
Further, the each component mass percent is as follows:
Further, described adhesive is gelatine.
Further, described stabilizing agent is polyvinyl alcohol.
Further, described cork powder fineness is 400～700 orders.
Beneficial effect of the present invention:
