Description
Technical field
The present invention relates to the preparation method of lead-acid accumulator releasing agent.
Background technology
It is that metal is made when casting due to mould, therefore there is the feature of rapid heat dissipation, add dies cavity groove narrow
Shallow so that the aluminium alloy under melting pan state is difficult to be full of mould.In order to ensure the ratio of briquetting of casting grid, it is necessary at die surface
And between cast alloys, spray releasing agent.Releasing agent is a kind of functional materials between mould and finished product.Releasing agent has
Chemical resistance, at the chemical analysis with different resins, particularly styrene and amine, is not dissolved during contact.Releasing agent also has
There is heat-resisting and stress performance, be not easily decomposed or wear and tear；Releasing agent is adhered on mould be not transfer on processed product, no
Obstruction is sprayed paint or other secondary machining operation.Owing to being molded, extruding, rolling, molding, the developing rapidly of the technique such as lamination, the demoulding
The consumption of agent is also significantly increased.Releasing agent is used in an interface coating of two body surfaces being prone to adhesion each other,
It can make body surface be prone to depart from, smooth and clean.Releasing agent is widely used in die cast metal, polyurethane foam and elasticity
In the various coining operation such as body, fiberglass reinforced plastics, injection molded thermoplastic's plastics, vacuum foam sheet material and extrudate.?
In mold pressing, other plastics compounds can be exuded on interface such as plasticizer etc. sometimes, is at this moment accomplished by a surface scavenger
Remove it.
The releasing agent of International Industry developed country many employings metal spray tank fill, due to metal spray tank sealing property relatively
Good, releasing agent oxidation can be avoided or be mixed into impurity, can guarantee that purity when releasing agent dispatches from the factory.Large-scale injection-moulding device is arranged on
Indoor, variation of ambient temperature is little, on the use of spray release agents without impact.But the mold temperature of die forming to be examined
Consider, the releasing agent that thermal stability to be selected is good, typically require that the heat decomposition temperature of releasing agent is higher than the mold temperature of molding.No
Carbonization knot humiliation phenomenon so can occur.High-grade goods and need secondary operations to select the releasing agent being suitable for secondary operations.It is anti-
Stop ring environment pollution, select nonflammable, abnormal smells from the patient and the little releasing agent of toxicity.In releasing agent is selected, economy is to neglect
Depending on key factor.Ropy releasing agent can make product surface produce be full of cracks wrinkle, affects product appearance and mould uses the longevity
Life, and bring environmental pollution.Selecting high-quality spray release agents, price is higher, but overall economic efficiency is high.
At present, generally use the releasing agent prepared by cork powder, sodium silicate and water in storage battery factory, be sprayed in mould
Chamber, acts primarily as insulation, heat insulation, lubrication, it is ensured that aluminium alloy is full of the effect of mould.But, existing preparation method is prepared
The dilutest poor adhesion of releasing agent, or the thickest the thickest in die surface accumulation, and releasing agent effective time is short.
Summary of the invention
The lead-acid accumulator releasing agent denseness that the technical problem to be solved is traditional is the dilutest or the thickest, inconvenience
In use, and releasing agent effective time is short, present invention aim at providing the preparation of a kind of new lead-acid accumulator releasing agent
Method, reaches the easy demoulding, easily operation, less residue, effective time long, and the thickness evenness of grid can be played Accommodation
Purpose.
The technological process of the present invention is as follows:
One, 4 ~ 5 parts of sodium silicate, 80 ~ 100 parts of water are put into warming pan, be heated to 200 DEG C ~ 300 DEG C, stir 10 ~ 30 points simultaneously
Clock, makes sodium silicate and water mix homogeneously；
Two, the cork powder that 10 ~ 20 parts of fineness are 180 ~ 200 mesh is poured in the warming pan in step one lentamente, stir 3 simultaneously
~ 8 minutes, it is allowed to uniform with the liquid mixing in step one；
Three, 2.5 ~ 5 parts of aluminum phosphate, 80 ~ 100 parts of water are added in the warming pan in step 2, be heated to 200 DEG C ~ 300 DEG C, and
Keep 30 ~ 50 minutes, then natural cooling；
Four, the mixture after cooling is filtered by 60 ~ 80 mesh sieve, and load in container.
Mesh number, physics is defined as granularity or the fineness degree of material, and general definition refers to screen cloth hole count in 1 inch,
Mesh number is the biggest, illustrates that raw meal particle size is the thinnest；Mesh number is the least, illustrates that raw meal particle size is the biggest.Mesh number in step 2 of the present invention refers to
The dynamics of material, the mesh number in step 4 refers to screen cloth hole count in 1 inch.
The present invention compared with prior art, has the advantage that and beneficial effect:
1, the preparation method of lead-acid accumulator releasing agent of the present invention, have employed the sodium silicate of specific proportioning, cork powder and water, right
During the heating of its mixture, it is heated to 200 DEG C ~ 300 DEG C, and keeps 30 ~ 50 minutes, and finally make mixture natural cooling, pass through
Experimental verification, the easy demoulding of releasing agent using this preparation method to make, easily operation, less residue and product denseness are moderate, it is possible to
The thickness evenness of grid is played Accommodation；
2, the preparation method of lead-acid accumulator releasing agent of the present invention, adds aluminum phosphate in step 3, through experimental verification,
Add the effective time of releasing agent of aluminum phosphate for being not added with the effective time of releasing agent of aluminum phosphate, had significantly
Improve.
