Description

A kind of lead-acid accumulator cast welding releasing agent
Technical field
The present invention relates to technical field of mold release, more particularly, to a kind of lead-acid accumulator cast welding releasing agent.
Background technology
Polar plate of lead acid storage battery welding in recent years is eliminated substantially using manual mode, and provisions of the relevant regulations issued by the State accumulator plate Machine automatic cast welding must be used with bus-bar welding.Cast welding mode is typically all:Positive plate, the dividing plate folded(Glass fibers Tie up separator paper), negative plate pole plate group, after lug is cleared up, insertion cast welded mold is filled in the die cavity of lead liquid, passes through lead liquid 500 DEG C or so of temperature, makes lug surface melting, then it is cold it is dynamic make lead liquid solidification forming, then by pole plate group and cast welded mold phase Separation, just realizes multi-disc pole plate and connects together, and the purpose of mould spraying releasing agent helps pole group and mould after welding Separation, it is ensured that the smooth full light of bus-bar.Also it is exclusively used in lead-acid accumulator cast welding releasing process without a class in the prior art In releasing agent, but use some analogous technical fields in releasing agent carry out assisted demoulding operation, due to not being special Releasing agent will produce a series of problems, such as be difficult to clean off the impurity such as the lead oxide of lead acid accumulator pole group surface attachment, meeting Cause loose contact and reduce the life-span of battery;Although and some releasing agents can understand the lead oxide of accumulator pole group surface attachment Deng impurity, but damage is also caused in itself to pole group, influence the life-span of battery;Because these releasing agents are not lead-acid accumulator castings The special releasing agent of releasing process is welded, its usage amount is also larger, virtually adds manufacturing cost;Cast welding operating temperature typically exists 400~500 DEG C, using effect is poor at such a temperature for existing conventional releasing agent, because resistance to elevated temperatures is not good, releasing agent Evaporation rate is too fast, causes continually to need manually to add releasing agent, causes manpower to waste.
The content of the invention
To solve the above problems, ensure that service life of lead accumulator is unaffected and can realize the invention provides one kind Effectively remove the lead-acid accumulator cast welding releasing agent of bus-bar surface oxidation lead.
To achieve the above object, the technical solution adopted by the present invention is as follows:

Surface cleaning agent is dissolved in after water in alkalescence in technical solution of the present invention, can effectively dissolve the oxide of lead, but not Mould can be made to sustain damage, mould bus-bar die cavity is remained complete, promote the full light in bus-bar surface after welding. Lubricant can form one layer after being mixed with lubricant additive, long-chain fatty alcohol APEO, wax additive in die cavity Film, performance is stable in weakly alkaline solution, bus-bar is smoothed out with die cavity in the demoulding, prevents the demoulding has some setbacks from causing to conflux Row pulls.
Preferably, lubricant is one kind in mineral oil, vegetable oil or artificial oil.
This mineral oil, vegetable oil and artificial oil have more excellent oxidation stability, resistance to emulsion.
Preferably, surface cleaning agent is one kind in sodium carbonate, sodium hydroxide or triethanolamine.
Above-mentioned surface cleaner all has weakly alkaline material to be dissolved in after water, and the materials such as steel, iron, nickel are not worked, And there is larger corrosivity to its alloy, the lead oxides in mould bus-bar die cavity can be made to depart from mold cavity surface, make type Chamber surface is complete, also promotes the full light in bus-bar surface.
Preferably, wax additive is OPE, atoleine, microcrystalline wax, natural paraffin wax or polyethylene One kind in wax.
Above-mentioned wax additive has higher melt and with low viscosity, and it can promote lead liquid to have well after adding Mobility, can reduce the adhesion between lead liquid and mould, it is easy to be stripped.
Preferably, lubricant additive is one in AEO, fatty acid sorbitan or polysorbate Kind.
Preferably, emulsifying agent is one kind in glyceryl monooleate, Octoxinol or methyl glycol fatty acid ester.
Preferably, antirust agent is polynary esters antirust agent.
Preferably, polynary esters antirust agent is triethanolamine borate, pentaerythritol ester, sorbitan gear oleate Or one kind in inositol hexaphosphate.
Preferably, solvent is water.
Preferably, the lead-acid accumulator cast welding is made with releasing agent by following steps:
a)It is fitted into after wax additive is mixed with surface cleaning agent in preparing tank, is heated to being completely dissolved;
b)Long-chain fatty alcohol APEO, emulsifying agent, lubricant and lubricant additive are added in step a obtained mixed Close in liquid and stir, and heating makes temperature control at 140~160 DEG C;
c)Solvent is heated to 90~100 DEG C, is slowly added into afterwards in mixed liquor made from step b, solvent is closed after adding Heating;
d)Antirust agent is added into mixed liquor made from step c and is stirred, lead-acid accumulator cast welding releasing agent is made.
Therefore, the invention has the advantages that:
(1)The lead oxides that can effectively go in depolarization group surface and mold cavity, make die cavity and pole group surface completely smooth, The good bus-bar welding effect of lead-acid accumulator is realized, its high-rate discharge ability is improved, so that it is guaranteed that its longer use longevity Life;
(2)The mobility of lead liquid can be promoted during cast welding, the adhesion between lead liquid and mould is reduced, it is easy to be stripped;
(3)A kind of protection effectively can be carried out to mould, generate one layer of oxidation-resistant film, extend die life;
(4)Ensure that service life of lead accumulator and performance are unaffected.
