The technical scheme of the utility model is further specifically described below through examples and with reference to the accompanying drawings. In the specification, the same or similar reference numerals denote the same or similar components. The following description of embodiments of the present utility model with reference to the accompanying drawings is intended to illustrate the general inventive concept and should not be taken as limiting the utility model.
Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in the drawings in order to simplify the drawings.
According to one general technical concept of the present utility model, there is provided an insulating tape. The insulating tape includes: a base layer; an adhesive layer disposed on the base layer; and a release paper disposed on the adhesive layer; wherein, the adhesive layer is formed with an exhaust groove structure.
Fig. 1 is a schematic view showing the structure of an insulating tape according to an exemplary embodiment of the present utility model, in which the entire structure of the insulating tape is shown in a front view, and release paper is omitted in order to show the structure of the vent groove. Fig. 2 is a cross-sectional view showing an insulating tape according to an exemplary embodiment of the present utility model.
Referring to fig. 1 and 2, an insulating tape 10 is provided according to the present utility model. The insulating tape 10 includes: a base layer 11; an adhesive layer 12 disposed on the base layer 11; and a release paper 13 disposed on the adhesive layer 12; wherein the adhesive layer 12 is formed with a vent groove structure 120. According to the utility model, the exhaust groove structure is arranged on the adhesive layer of the insulating adhesive tape, so that gas existing between the adhesive tape and the plate in the application process of the insulating adhesive tape can escape from the exhaust groove structure in time, thereby solving the problem of bubbles existing in the insulating adhesive tape in the prior art, and further ensuring the durability and stability of the insulating property while ensuring the appearance of the plate.
Referring to fig. 1 and 2, a vent structure 120 is formed on the surface of the adhesive layer 12 according to an exemplary embodiment of the present utility model. Specifically, the vent structure 120 may be formed on, for example, an adhesive surface of the adhesive layer 12 (i.e., a surface of the adhesive layer 12 to be in contact with an object to be glued of a sheet material), which is generally referred to as a surface of the adhesive layer 12 covered with the release paper 13. In this way, when the adhesive layer 12 is applied to the board waiting object during application of the insulating tape 10, air that occurs between the insulating tape 10 and the board waiting object can easily escape through the air vent structure 120, thereby effectively avoiding the problem of air bubbles that exist in the prior art insulating tape.
As shown in fig. 1 and 2, according to an exemplary embodiment of the present utility model, the surface of the release paper 13 facing the adhesive layer 12 is formed with an embossing structure 130, and the plurality of vent groove structures 120 are formed by embossing the embossing structure 130 of the release paper 13. Specifically, as shown in fig. 2, the release paper 13 is formed with an embossed structure 130 protruding from the surface thereof. In the manufacturing process of the insulating tape 10, the release paper 13 is applied to the adhesive layer 12, wherein the surface of the release paper 13 on which the embossed structure 130 is formed faces the adhesive surface of the adhesive layer 12, so that the concave vent structure 120 conforming to the embossed structure 130 is embossed on the adhesive surface of the adhesive layer 12.
Referring to fig. 1 and 2, the vent structures 120 extend across the entire surface of the adhesive layer 12 according to an exemplary embodiment of the utility model. Specifically, the vent groove structure 120 includes a plurality of vent grooves 121 on the surface of the adhesive layer 12, the plurality of vent grooves 121 being staggered to communicate with each other. In the exemplary embodiment shown in fig. 1 and 2, the plurality of air discharge grooves 121 communicate with each other in a manner that a plurality of rows and columns are vertically staggered from each other. In this way, during application of the insulating tape 10, air present at any position between the insulating tape 10 and the board waiting object can easily enter the vent groove 121 in the vicinity of the position and escape through the vent groove structure 120. It should be noted that, in the illustrated exemplary embodiment, the plurality of air discharge grooves 121 are communicated with each other in a form in which a plurality of rows and a plurality of columns are vertically staggered with each other, however, in some other embodiments, the plurality of air discharge grooves 121 may be communicated with each other in any other suitable form according to actual needs; in still other embodiments, the plurality of vent grooves 121 may also take the form of portions of the vent grooves 121 that communicate with one another and portions of the vent grooves 121 that do not communicate with one another; the utility model is not limited in this regard as long as air/bubbles are facilitated to escape.
Referring to fig. 1 and 2, the thickness of the adhesive layer 12 may be in the range of about 10 μm to about 100 μm according to an exemplary embodiment of the present utility model. The ratio between the depth of each vent slot 121 and the thickness of the adhesive layer 12 may be in the range of about 0.1 to about 0.9. For example, assuming that the thickness of the base layer 11 in the insulating tape 10 is about 100 μm and the thickness of the adhesive layer 12 is about 40 μm, the depth of the vent groove 121 may be in the range of about 4 μm to about 36 μm. The thickness of the adhesive layer 12 and/or the depth of the vent grooves 121 can be adjusted by those skilled in the art according to the actual requirements, as long as it is ensured that air/bubbles can escape through the vent groove structure while not affecting the adhesive properties of the adhesive layer.
Meanwhile, as shown in fig. 1 and 2, the interval between adjacent vent grooves 121 may be in the range of about 0.1mm to about 5mm according to an exemplary embodiment of the present utility model. The person skilled in the art can reasonably set the spacing between adjacent vent grooves 121 according to the actual requirements, as long as it can ensure that air/bubbles can escape through the vent groove structure while not affecting the adhesive properties of the adhesive layer.
As shown in fig. 1 and 2, a release paper 13 is releasably disposed on the adhesive layer 12 according to an exemplary embodiment of the present utility model. In this way, before the insulating tape 10 is applied to the sheet material waiting object, the protective release paper 13 is peeled off from the insulating tape 10 (i.e., the adhesive layer 12), and the air vent structure 121 formed on the adhesive surface is exposed while the adhesive surface of the adhesive layer 12 is exposed.
As shown in fig. 1 and 2, according to an exemplary embodiment of the present utility model, the insulating tape 10 may be a heat-curable and/or light-curable half-structured pressure-sensitive adhesive tape (SSIT) so as to be suitable for an electrical insulation solution such as power battery module assembly. The exhaust groove structure of the semi-structure pressure-sensitive adhesive tape is beneficial to exhausting air/bubbles and other gases, the adhesive surface can be leveled before the semi-structure pressure-sensitive adhesive tape is not cured, and then the adhesive strength can be improved after the semi-structure pressure-sensitive adhesive tape is cured, and the problem that the durability and the stability of adhesive tape adhesion are affected due to the fact that the gases cannot be exhausted in the related technology can be avoided.
According to the insulating adhesive tape provided by the various exemplary embodiments of the utility model, the exhaust groove structure is arranged on the adhesive layer, so that gas existing between the adhesive tape and the plate in the application process of the insulating adhesive tape can escape from the exhaust groove structure in time, the problem of bubbles existing in the insulating adhesive tape in the prior art is solved, and the durability and the stability of the insulating performance are ensured while the appearance of the plate is ensured.
Those skilled in the art will appreciate that the embodiments described above are exemplary and that modifications may be made by those skilled in the art, and that the structures described in the various embodiments may be freely combined without conflict in terms of structure or principle.
