For solving the problems of the technologies described above, we have proposed a kind of protective membrane adhesive tape structure, and this adhesive tape has modest viscosity, feature corrosion-resistant, high temperature resistant, that easily remove.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of protective membrane adhesive tape structure, comprises along protective membrane length of tape bearing of trend and is set up in parallel You Jiao district and adhesive-free area; Described You Jiao district comprises PET polyester film substrate layer and can resistant to elevated temperatures glue-line, and described PET polyester film substrate layer upper surface is provided with anti-scratch layers, and the upper surface of described anti-scratch layers is provided with top layer that can acid and alkali-resistance; The width 2-3mm of described adhesive-free area;
And described PET polyester film substrate layer thickness 0.006-0.080mm, described can resistant to elevated temperatures bondline thickness 0.006-0.050mm, described anti-scratch layers thickness 0.020-0.070mm, described skin depth 0.020-0.070mm.
Preferably, describedly can be provided with PE or PET release film layer by resistant to elevated temperatures glue-line lower surface.
Preferably, described anti-scratch layers material is PC.
Preferably, described top layer that can acid and alkali-resistance is PVC layer.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is to design according to the processing requirement of lithium cell.The design of adhesive-free area is the protective membrane adhesive tape in order to remove easily lithium cell surface; The glue-line of PET polyester film substrate layer lower surface setting has advantages of high temperature resistant (85-100 DEG C), modest viscosity; The design of anti-scratch layers is that protection lithium cell can not be bruised or scratch in operation transfer process; The upper surface of anti-scratch layers is provided with top layer that can acid and alkali-resistance, can prevent from being dropped in the corrosion that the electrolytic solution on lithium cell surface causes it, ensures the complete, attractive in appearance of lithium cell outward appearance.The thickness of whole protective membrane adhesive tape is in about 0.2mm, not thick also quite well, sticks on lithium cell surface (on aluminum plastic film) very convenient.
