As shown in fig. 2, which is a practical application of the high-strength stretch-proof hand tape of the present embodiment, in the present embodiment, the main release layer 1 is firstly torn off from one side of the double-sided adhesive layer 2, the double-sided adhesive layer 2 is attached to the inner side of the insulating cover 7, then the remaining whole tape is bent around the edge of the insulating cover 7 to the outer side of the insulating cover 7, and the silicone rubber layer 5 is attached to the outer side of the insulating cover 7. As shown in fig. 2, the one side of laminating in the silicone rubber layer 5 and the insulating boot 7 outside this moment, the supplementary type layer 4 that tears of the edge of silicone rubber layer 5 has not peeled off yet, when needs assemble insulating boot 7 and battery module, can be through putting the hand in supplementary type layer 4 formation tear hand position department, it together peels off with PI tensile layer 6 to tear supplementary type layer 4 and drive the silicone rubber layer 5 and the PI tensile layer of whole double-sided adhesive layer 2 another side, only last double-sided adhesive layer 2 that only remains promptly, alright glue the battery module on the double-sided adhesive layer 2 of insulating boot 7 inboard this moment, realize the assembly of insulating boot 7 and battery module. When assembling insulating boot 7 and battery module promptly, can will assist again to tear from type layer 4 and expose the another side of two-sided adhesive layer 2 and laminate with the battery module through placing insulating boot 7 earlier after suitable position, guaranteed that two-sided adhesive layer 2 can closely laminate with the battery module, avoided the assembly of insulating boot 7 with the battery module to shift when the perk phenomenon can not appear, further improved the assembly yield of insulating boot 7 with the battery module.
In this embodiment, PI (polyimide film) is used as the tensile layer to be bent at the outermost side, and the PI film is not easily torn off during bending around the edge of the insulating cover 7, and is also not deformed during folding due to the soft texture of the PI film itself, thereby ensuring high tensile strength and insulation of the entire tape.
In addition, in the embodiment, the silicone rubber layer 5 is silicone adhesive glue processed by vacuum centrifugal oscillation, and since the silicone rubber layer 5 is formed by curing silicone adhesive, although the adhesiveness is not very strong, it is necessary to ensure good self-tightness when it is used as an adhesive, so that the vacuum centrifugal oscillation processing is performed to ensure that the inside of the glue has no air or air bubbles and then the glue is coated on the PI tensile layer 6 to ensure tightness; meanwhile, since the silicone rubber layer 5 has a soft viscosity and does not damage an adherend, the silicone rubber layer 5 used in the present invention as a layer of glue which is attached to the outside of the insulating cover 7 after being bent does not remain on the surface of the insulating cover 7 during peeling.

In other equivalent embodiments, the plane size of the double-sided adhesive layer 2 is controlled to be between 8mm × 12mm and 12mm × 16 mm.
Referring to fig. 1 to fig. 3, a third embodiment of the present invention is:
in addition to the above first or second embodiment, in this embodiment, as shown in fig. 1 or fig. 2, a single-sided release PET layer 3 is further included between the double-sided adhesive layer 2 and the silicone rubber layer 5.

Because the silicone oil between the main release layer 1 and the double-sided adhesive layer 2 needs to have a certain release force, the coating amount of the silicone oil between the main release layer 1 and the double-sided adhesive layer 2 is 2-7 g/inch; the silicone oil coated on the auxiliary release layer 4 only needs to coat a layer of silicone oil in a light and thin manner according to actual needs so that the silicone oil has a smooth effect, and the coating amount is not required.
In summary, the high-strength tensile tear-resistant hand tape and the battery pack provided by the utility model are formed by stacking the main release layer, the double-sided adhesive layer, the single-sided release PET layer, the silicone rubber layer, the PI tensile layer and the auxiliary release layer, wherein the double-sided adhesive layer is formed by sandwiching the double-sided release PET layer between the two acrylic adhesive layers, so that the double-sided adhesive effect of the double-sided adhesive layer can be ensured, and meanwhile, the high-strength tensile tear-resistant hand tape and the battery pack have certain tensile strength. The utility model firstly pastes one side of the double-sided adhesive layer on the inner side of the insulating cover for assembling with the battery module by tearing the main body release layer, then the integral adhesive tape is bent to the outer side of the insulating cover around the edge of the insulating cover by utilizing the tearing resistance of the PI tensile layer so as to ensure that the extra silicone rubber layer is attached to the outer side of the insulating cover, an auxiliary release layer is added at the edge of the side, which is jointed with the outer side of the insulating cover, of the silicone rubber layer to form a tearing hand position, the insulating boot can be placed in a proper position and then the silicone rubber layer and the PI tensile layer are torn through the auxiliary release layer to expose the other side of the double-sided adhesive layer, so that the other side of the double-sided adhesive layer is attached to the battery module and fixed, the double-sided adhesive layer can be tightly attached to the battery module, the assembly displacement of the insulating boot and the battery module is avoided, the tilting phenomenon of the double-sided adhesive layer is also avoided, and the assembly yield of the insulating boot and the battery module is integrally improved.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
