Description
Technical field
The present invention relates to the preparation methods of lead-acid accumulator releasing agent.
Background technology
In casting since mold is made of metal, therefore there are the characteristics of rapid heat dissipation, it is narrow to add in dies cavity groove
It is shallow so that the aluminium alloy under melting pan state is difficult to full of mold.In order to ensure the ratio of briquetting of casting grid, it is necessary in die surface
Releasing agent is sprayed between cast alloys.Releasing agent is a kind of functional materials between mold and finished product.Releasing agent has
Chemical resistance is not dissolved in the chemical analysis with different resins, particularly styrene and amine, contact.Releasing agent also has
There is heat-resisting and stress performance, be not easily decomposed or wear；Releasing agent is adhered on mold and is not transfer on processed product, no
Interfere spray painting or other secondary machining operations.Due to the rapid development for being molded, squeezing out, roll, being molded, the techniques such as be laminated, demoulding
The dosage of agent is also significantly increased.Releasing agent is used in an interface coating of two body surfaces for being easy to adhesion each other,
It can make body surface be easy to be detached from, it is smooth and clean.Releasing agent is widely used in die cast metal, polyurethane foam and elasticity
In the various coining operations such as body, fiberglass reinforced plastics, injection molded thermoplastic's plastics, vacuum foam sheet material and extrudate.
In molding, other plastics compound such as plasticizer can be exuded on interface sometimes, at this moment just a surface scavenger is needed
Remove it.
International Industry developed country mostly using the filling releasing agent of metal spray tank, due to metal spray tank sealing performance compared with
It is good, releasing agent can be avoided to aoxidize or be mixed into impurity, can guarantee purity during releasing agent manufacture.Large-scale injection-moulding device is mounted on
Interior, variation of ambient temperature is small, on the use of spray release agents without influence.But the mold temperature of die forming to be examined
Consider, the releasing agent that select thermal stability good generally requires the heat decomposition temperature of releasing agent to be higher than molding mold temperature.No
Charing knot humiliation phenomenon can so occur.High-grade product and secondary operation is needed to select the releasing agent for being suitable for secondary operation.It is anti-
Only environmental pollution will select nonflammable, the releasing agent of smell and small toxicity.In releasing agent selection, economy is can not to neglect
Depending on an important factor for.Ropy releasing agent can make product surface generate cracking wrinkle, influence product appearance and mold uses the longevity
Life, and bring environmental pollution.Select the spray release agents of high quality, higher price, but overall economic efficiency high.
At present, the releasing agent prepared by cork powder, sodium metasilicate and water is generally used in storage battery factory, is sprayed in mold
Chamber, it is main to play heat preservation, heat-insulated, lubrication, it is ensured that aluminium alloy is full of the effect of mold.But what existing preparation method was prepared
The too dilute poor adhesion of releasing agent or it is too thick accumulated in die surface too thick, and releasing agent effective time is short.
Invention content
The technical problems to be solved by the invention are that traditional lead-acid accumulator is too dilute or too thick with releasing agent consistency, inconvenient
In using, and releasing agent effective time is short, present invention aims at provide a kind of preparation of new lead-acid accumulator releasing agent
Method, it is long to reach easy mold release, easy to operate, less residue, effective time, and can play corrective action to the thickness evenness of grid
Purpose.
The technological process of the present invention is as follows：
First, 4~5 parts of sodium metasilicate, 80~100 parts of water are put into warming pan, are heated to 200 DEG C~300 DEG C, stir simultaneously
10~30 minutes, it is uniformly mixed sodium metasilicate and water；
2nd, cork powder of 10~20 parts of fineness for 180~200 mesh is slowly poured into the warming pan in step 1, together
When stir 3~8 minutes, be allowed to be uniformly mixed with the liquid in step 1；
3rd, 2.5~5 parts of aluminum phosphates, 80~100 parts of water are added in the warming pan in step 2, be heated to 200 DEG C~
300 DEG C, and kept for 30~50 minutes, then natural cooling；
4th, 60~80 mesh sieve of mixture after cooling are filtered, and be packed into container.
Mesh number, physics are defined as the granularity or fineness degree of material, and general definition refers to hole count of the sieve in 1 inch,
Mesh number is bigger, illustrates that material size is thinner；Mesh number is smaller, illustrates that material size is bigger.Mesh number in step 2 of the present invention refers to
The dynamics of material, the mesh number in step 4 refer to hole count of the sieve in 1 inch.
Compared with prior art, the present invention having the following advantages that and advantageous effect：
1st, the preparation method of lead-acid accumulator releasing agent of the present invention, employ the sodium metasilicate of specific proportioning, cork powder and
Water when being heated to its mixture, is heated to 200 DEG C~300 DEG C, and kept for 30~50 minutes, and finally make mixture naturally cold
But, it by experimental verification, is fitted using releasing agent easy mold release, easy to operate, less residue and product consistency made of the preparation method
In, corrective action can be played to the thickness evenness of grid；
2nd, the preparation method of lead-acid accumulator releasing agent of the present invention, adds aluminum phosphate in step 3, by experiment
Verification, has added the effective time of releasing agent of aluminum phosphate to have for the effective time for the releasing agent for being not added with aluminum phosphate
It is significant to improve.
