Description
Technical field
The present invention relates to battery manufacturing field more particularly to a kind of mixing paste preprocess methods.
Background technique
Lead carbon battery is the state-of-the-art technology in lead-acid accumulator field, has many advantages compared to lead-acid battery.It can apply
In new energy vehicle, such as: hybrid vehicle, electric bicycle field；It can also be used for new energy energy storage field, such as scene
Electrification energy storage etc..So-called lead carbon battery is exactly the technology come out from traditional lead-acid battery evolution, it is in the negative of lead-acid battery
The carbon material (powdered) of 0.2%-4% is added in extremely, this carbon material can inhibit the irreversible sulfate of negative electrode active material
Change, to improve the cryogenic property and charge acceptance energy of electrode.Mixing paste preprocess method is that directly carbon material is added at present
Mixing paste mixing is carried out into paste mixing machine, because the quantity of added carbon material is few, conventional plus carbon method is it is difficult to ensure that carbon material and lead
Powder is uniformly mixed.
Summary of the invention
The present invention is in view of the above-mentioned problems, propose a kind of mixing paste preprocess method.
The technical solution adopted by the present invention is as follows:
A kind of mixing paste preprocess method, includes the following steps,
S1: stirring lead powder, so that lead powder is under flow regime；
S2: when lead powder is under flow regime, carbon dust being poured into lead powder, is mixed so that carbon dust flows together with lead powder
It is even.
This method has the beneficial effect that, lead powder is stirred first with blender or manually, so that lead powder is in flowing
Under state, it is in lead powder under flow regime and carbon dust is added, the carbon dust under flow regime is uniformly mixed with lead powder, when
Lead powder and carbon dust are placed in progress mixing paste processing in paste mixing machine after mixing, by the mixture of lead powder and carbon dust.Mixing paste has been handled
It is strong that negative electrode lead-carbon mixing material painting cream stability is made in Cheng Hou, and the binding ability of pole plate and lead plaster is strong.
Lead powder made from this method is uniformly mixed with the mixture of carbon dust, the lead powder and toner mixture being mixed to get into
The processing of row mixing paste, after the completion of mixing paste processing, obtained negative electrode lead carbon mixing material painting cream stability is strong, and the combination of pole plate and lead plaster
Ability is strong.
Optionally, the temperature when lead powder is mixed with carbon dust is 0 DEG C~100 DEG C, ambient humidity when mixing is 0~
95%rh.
Optionally, the mass ratio of the carbon dust and lead powder is 1:500~1:25.
Optionally, the carbon dust continues to stir 0.5~100min of mixture after mixing with lead powder.
The beneficial effects of the present invention are: lead powder obtained is uniformly mixed with the mixture of carbon dust, the lead powder being mixed to get with
Toner mixture is carrying out mixing paste processing, and after the completion of mixing paste processing, obtained negative electrode lead carbon mixing material painting cream stability is strong, and pole
The binding ability of plate and lead plaster is strong.
Specific embodiment:
The present invention will be described in detail below.
Embodiment 1
25Kg lead powder is placed in blender and is stirred, pours into 1Kg carbon dust into lead powder while stirring lead powder, when carbon dust is complete
When entering in lead powder entirely, continues the mixture 5min for stirring lead powder and carbon dust, the temperature of mixture is controlled in entire whipping process
It is 25 DEG C, control ambient humidity is 65%rh.Mixture is put into paste mixing machine after the completion of stirring and carries out mixing paste.
Embodiment 2
500Kg lead powder is placed in blender and is stirred, 1Kg carbon dust is poured into lead powder while stirring lead powder, works as carbon dust
When completely into lead powder, continues the mixture 7min for stirring lead powder and carbon dust, the temperature of mixture is controlled in entire whipping process
Degree is 35 DEG C, and control ambient humidity is 45%rh.Mixture is put into paste mixing machine after the completion of stirring and carries out mixing paste.
The above description is only a preferred embodiment of the present invention, not thereby limits scope of patent protection of the invention, all
It is to carry out equivalent transformation with content described in description of the invention, is directly or indirectly used in other relevant technology necks
Domain similarly includes within the scope of the present invention.
