Description
Technical field
The utility model relates to a kind of composite coating for battery case, and specifically, composite coating described in the utility model is not only applicable to cylindrical battery, is also applicable to square battery, can be cell, also can power brick in any combination.
Background technology
Existing battery case surface insulation treatment technology is all adopt thermal shrinkable sleeve under normal circumstances, as PVC thermal shrinkable sleeve, this thermal shrinkable sleeve technique is outer surface one deck PVC film being coated on battery, make PVC film packaged battery shrink wrapped tightly by heating, good insulation effect can be reached at battery surface.But in the occasion that some are special, if battery surface contacts some water, even battery is when being immersed in water, and so this PVC thermal shrinkable sleeve battery can not play water-proof function, once touch water, PVC thermal shrinkable sleeve battery will be short-circuited.
So, the short circuit that imagination of the present utility model uses a kind of composite coating to exist to overcome PVC thermal shrinkable sleeve technique, thus be guided out design concept of the present utility model.
Utility model content
The purpose of this utility model is to provide a kind of composite coating for battery case, and object is waterproof and the insulation effect of improving battery.
The coating of the waterproof coating film treatment of a kind of battery case that the utility model provides, is characterized in that:
1. for a composite coating for battery case, it is characterized in that described composite coating is first deposit one deck waterproof coating on the superficial layer of battery case, and then deposit a floor height insulating coating, the thickness of every layer of coating is between 0.1-1 μm.
2. the coating layer thickness of waterproof coating and high insulating coating is respectively 0.3-0.8 μm.
3. described composite coating gross thickness is 0.5-1.5 μm.
4. for the cell of cylindrical battery, square battery, or be the power brick of combination in any between them.
Described coating shaping method can adopt vacuum coating technology, and as organic high molecular nanometer coating thin film, this vacuum coating is flexible and convenient to use, especially carries out plated film when number of batteries is less; Coating procedure can repeatedly circulate and the adjustable control of film thickness, safe and reliable, forms double-deck coating structure, also can carry out repeatedly the plated film of different materials, to obtain better more multifarious coating structure.
Coating Materials is organic polymer nano material mainly because this material have low-down dielectric constant, high insulation resistance, extremely low hydrone and corrosive gas penetrance, not with the dielectric constant of frequency change, better thermal stability.
This battery case waterproof thought and high molecular nanometer coatings, the surface being plated in battery case is coated with by the material of good insulation properties and water resistance, instead of adopt the coating of pyrocondensation mantle, the water resistance of such battery obtains good raising, avoids battery to cause the short circuit of battery when contacting water.There is excellent temperature stability (room temperature ~ 200 DEG C).Can overcome and avoid existing thermal shrinkable sleeve technique to lose efficacy because battery temperature raises, the even destroyed defect causing battery short circuit.
Accompanying drawing explanation
Fig. 1 is the structural representation of described composite coating.
In figure, 1, high insulating coating; 2, waterproof coating; 3, cell superficial layer.
Embodiment
In order to make the object of shell composite coating of the present invention, feature and advantage more become apparent, below in conjunction with the drawings and specific embodiments, this shell composite water-proof coating is described further.
It is below the embodiment that shell composite coating of the present invention is described according to specific instantiation, those of ordinary skill in the art can be understood structure, advantage and effect of shell composite coating of the present invention easily by the content disclosed in following examples.
This shell composite coating also can be implemented by other different instantiation or be applied, and the every details in this specification also based on different viewpoints and application, can carry out various modification and change under not departing from the spirit of this creation.
Moreover, graphic with the signal of the simplification shown in Fig. 1, and the basic conception of this shell composite coating is only described in a schematic way, therefore graphic in only show the assembly relevant with shell composite coating of the present invention but not component count, shape and size when implementing according to reality is drawn, it is actual when implementing, and the kenel of each assembly, quantity and ratio can do random change, and its assembly layout kenel may be more complicated.
Embodiment 1:
The method of this example employing vacuum coating first generates waterproof coating and is divided into three steps:
(1) gasification of coating: even if coating evaporation, distillation or sputtered, namely forms the evaporation source of coating.
(2) migration of coating atom, molecule or ion: confess atom, molecule or ion through collision rift by evaporation source, produce multiple reaction.
(3) plating material atom, molecule or ion is at substrate deposit.
The high molecule nano material that vacuum coating uses in vacuum chamber after the cracking process of the vaporization of 150 DEG C and 650 DEG C, enter in the settling chamber under normal temperature, form film in the mode of vapour deposition under vacuum conditions, and equably plated film in the surface pinholes and slot of battery pack.Vapour deposition and metallising difference, for vapour deposition is not interrupted, make the product surface needing film be covered closely by Coating Materials, and then form free of pinholes, fine homogeneous, high-quality film.Film adopts chemical vapor deposition method, and whole process is vapor reaction, and whole process is carried out under vacuum, thus coating, very even, and this characteristic is that other application pattern is difficult to realize.
But again at the surface deposition one floor height insulating coating of waterproof coating, its deposition process and waterproof coating similar, the insulating coating be coated with, both tool slowed down weathering, and antiacid caustic corrosion also has insulation function.The thickness of two layers of coatings is respectively 0.1-1 μm of scope, and the thickness of recommendation is respectively 0.3-0.8 μm, and the gross thickness of recommendation is 0.5-1.5 μm, does not too thinly have waterproof and insulation function, too thick, easily peels off.
Concrete operation will be arranged according to the profile of battery and concrete space and be determined.
The principle describing this shell composite coating that the embodiment of shell composite coating described above is only exemplary and effect thereof, but not for limit shell composite coating, know and it will be understood by those skilled in the art that, when not departing from the spirit and scope of this shell composite coating, any changes and improvements done this shell composite coating are all in the scope of this shell composite coating.The rights protection scope of this shell composite coating, should as the claim of the application define be as the criterion.
