Description
Technical field
This utility model relates to a kind of insulant, particularly relates to a kind of insulating tape for wrapping up lithium battery group.
Background technology
In order to solve the growing energy and environmental problem, can reduce discharging and increasingly be paid attention to by whole world various countries, automobile be done to the problem of environmental pollution caused, the most best solution greatly develops new-energy automobile, especially electric automobile exactly.Thus, as a critical component of new-energy automobile, lithium battery group is just widely used along with the universal of new-energy automobile, and its power supply performance, stability and safety are development and the key factors of marketing further determining new-energy automobile.
New-energy automobile has the feature of high-speed mobile, strenuous vibration, hot operation and fast charging and discharging in motion, cause electrokinetic cell exist in use shock, stab, short connection, fall, soak, the potential danger such as baked wheaten cake, the millionth non-security rate of electrokinetic cell all can cause the most serious consequence, so, relative to traditional fuel automobile, the inflammable and explosive property of set of cells makes electric automobile the most fragile.Mostly developed countries is to use the high strength composites such as carbon fiber that set of cells is wrapped up protection at present, but this way composition is the highest.Therefore, a kind of wide isolation protective material of the suitability that can be used for the isolation of new-energy automobile lithium battery group safe insulation is needed badly.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of insulating tape for wrapping up lithium battery group, and it is by the improvement to adhesive tape structure so that adhesive tape has possessed the insulation stability of excellence and higher adhesive force.
For achieving the above object, this utility model is achieved through the following technical solutions:
A kind of insulating tape for wrapping up lithium battery group, it is sequentially provided with insulating barrier, the first pet layer, the first insulation glue-line, the second pet layer and the second insulation glue-line from top to bottom.
Preferably, the described insulating tape for wrapping up lithium battery group, wherein, the thickness of described insulating barrier is 1～5 μm.
Preferably, the described insulating tape for wrapping up lithium battery group, wherein, the thickness of described first pet layer is 10～40 μm.
Preferably, the described insulating tape for wrapping up lithium battery group, wherein, the thickness of described first insulation glue-line is 10～50 μm.
Preferably, the described insulating tape for wrapping up lithium battery group, wherein, the thickness of described second pet layer is 10～40 μm.
Preferably, the described insulating tape for wrapping up lithium battery group, wherein, the thickness of described second insulation glue-line is 10～50 μm.

The beneficial effects of the utility model are: this case is by the improvement of adhesive tape structure and optimization so that adhesive tape has possessed the insulating properties of excellence and higher adhesive force, can keep stronger adhesion in hot and humid environment；By using the combination of double-layer PET and insulating cement, improve stability and the toughness of insulating tape further, still can possess outstanding adhesive property when bending meeting adhesive tape.
Accompanying drawing explanation
Fig. 1 is the structural representation of the insulating tape for wrapping up lithium battery group of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art can implement according to this with reference to description word.
As it is shown in figure 1, the insulating tape for wrapping up lithium battery group of an embodiment is listed in this case, it is sequentially provided with insulating barrier the 1, first pet layer the 2, first insulation glue-line the 3, second pet layer 4 and the second insulation glue-line 5 from top to bottom.Use the combination of double-layer PET and insulating cement, stability and the toughness of insulating tape can be improved such that it is able to make adhesive tape still can possess outstanding adhesive property when bending.
In the above-described embodiments, the thickness of insulating barrier 1 is preferably 1～5 μm.
In the above-described embodiments, the thickness of the first pet layer 2 is preferably 10～40 μm.
In the above-described embodiments, the thickness of the first insulation glue-line 3 is preferably 10～50 μm.The insulating cement of this case may be preferred that high-temperature insulation pressure-sensitive.
In the above-described embodiments, the thickness of the second pet layer 4 is preferably 10～40 μm.
In the above-described embodiments, the thickness of the second insulation glue-line 5 is preferably 10～50 μm.
In the above-described embodiments, insulating barrier 1 is preferably non-silicon release layer.If using siliceous release layer, then under unexpected situation, when lithium battery breakage, internal composition is easily and silicon produces chemical reaction, thus causes battery overheated, produces potential safety hazard.
In the above-described embodiments, the surface of the first pet layer 2 and the second pet layer 4 is preferably frosting.Frosting can further enhance the bond strength of insulating cement and PET such that it is able to is effectively improved the service life of adhesive tape, it is ensured that the docile degree of adhesive tape.
The sheet resistance of the insulating tape that this case obtains is more than 1.1 × 1010Ω, breakdown voltage is respectively greater than 2500V (alternating current), more than 3500V (unidirectional current).At 70 DEG C, under 95% humidity, ring survey 48h is without warpage, without cull.Continue 48h and apply 1kg/inch2Power, without downslide displacement.Paste-tear 3 times without cull.
Although embodiment of the present utility model is disclosed as above, but it is not restricted in description and embodiment listed utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, it is easily achieved other amendment, therefore, under the general concept limited without departing substantially from claim and equivalency range, this utility model is not limited to specific details and shown here as the legend with description.
