Moreover, the embodiments of the present invention described in the following description are generally only some embodiments of the present invention, and not all embodiments. Therefore, all other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort shall fall within the protection scope of the present invention.

Example 1

As shown in figures 1-3, an electron radiation crosslinked polyethylene adhesive tape, including thickness for 0.3~5mm IXPE bubble cotton layer 1, the lower terminal surface that IXPE bubble cotton layer 1 is provided with tie coat 2 to the top that is located IXPE bubble cotton layer 1 is provided with from type layer 3 with tie coat 2 looks adaptation. After the electronic radiation crosslinked polyethylene adhesive tape in this embodiment is wound into a roll, the adhesive layer 2 on the lower end face is attached to the release layer 3.

In order to improve the mechanical property of the utility model, the reinforcing layer 4 is arranged in the IXPE foam layer 1 along the length direction of the IXPE foam layer, and the reinforcing layer is composed of reinforcing ribs 10 which are arranged in a straight line (as shown in figure 2) or in a grid (as shown in figure 3), so that the utility model can adapt to the occasions with heavy load.

Meanwhile, the side edge of the IXPE foam layer 1 is provided with easy-to-tear side edges 5, and the side edges of the easy-to-tear side edges 5 are provided with easy-to-tear openings 6 at intervals. Therefore, when the length of the adhesive tape needs to be adjusted, the adhesive tape does not need to use scissors and other tools, and only needs to apply a certain shearing force to the easy-to-tear opening 6, so that the adhesive tape can be broken along the easy-to-tear opening 6, and the use convenience of the adhesive tape is effectively improved.

In addition, the easy-to-tear line 11 is arranged at the connecting position of the easy-to-tear side edge 5 and the IXPE foam layer 1, and after the adhesive tape is attached to the surface of an adherend, the easy-to-tear side edge 5 can be torn off along the easy-to-tear line 11, so that the attractiveness of the adhesive tape left on the surface of the adherend is improved.

Example 2

As shown in fig. 4, the basic structure of embodiment 2 is the same as that of embodiment 1, except that the electronic radiation crosslinked polyethylene adhesive tape in this embodiment is a double-sided adhesive tape, wherein the upper and lower end surfaces of the IXPE foam layer 1 are both provided with adhesive layers 2, and the surface of the adhesive layer 2 located at the uppermost end is covered with a release layer 3, and when the electronic radiation crosslinked polyethylene adhesive tape in this embodiment is wound into a roll, the adhesive layer 2 at the lower end surface can be attached to the release layer 3.

Example 3

As shown in fig. 5 and 6, embodiment 3 is a modification of

embodiments

1 and 2, and compared with embodiment 1, it is different from embodiment 1 in that the reinforcing layer 4 in this embodiment is not continuous, but plays a reinforcing role in being disposed at intervals inside the IXPE foam layer 1. Therefore, an intermediate region 7 is formed between the adjacent reinforcing layers 4, meanwhile, the easy-to-tear opening 5 is arranged on the side surface of the intermediate region 7 in the embodiment, when shearing force is applied to the adhesive tape along the easy-to-tear opening 6, the electronic radiation cross-linked polyethylene adhesive tape in the embodiment can be torn along the intermediate region 7, and because the intermediate layer is not blocked by the reinforcing layers 4, the force used for tearing the adhesive tape in the embodiment can be greatly reduced, and the convenience is improved.

In addition, in order to tear the adhesive tape more conveniently, the embodiment is further wrapped with a section of lifting strip 8 inside the IXPE foam layer 1 and inside the middle area 7, the lifting strip 8 extends outwards to the outside of the easy-to-tear side edge 5, and the end of the lifting strip 8 is provided with a pull ring 9 which is convenient to grasp. Therefore, when the length of the electronic radiation crosslinked polyethylene adhesive tape is adjusted, force can be applied to the easy-to-tear opening 6 of the easy-to-tear side edge 5 only by pulling the lifting strip 8, and use is facilitated. Simultaneously, in the process of tearing the adhesive tape, the lifting strip 8 can guide the opening direction of the adhesive tape, so that the end face of the adhesive tape is smoother and smoother.

Although above-mentioned technical scheme can effectively promote the adhesive action of sticky tape, after exerting pressure to the sticky tape, the inside gas of partly shrinkage pool can be followed the side outflow of shrinkage pool 12, still has some to remain in shrinkage pool 12, leads to unable extrusion through the atmospheric pressure with its adhesion and adherend surface, leads to the unable promotion of adhesive force. Therefore, the utility model is also provided with an exhaust sealing seam 13 at the top of the concave hole 12. As shown in fig. 9, the vent seal seam 13 can be in a sealed state without applying a pressure to the IXPE foam layer 1. As shown in fig. 10, when pressure is applied to the IXPE foam layer 1, the vent seal seam 13 can be deformed, and thus the air in the concave hole 12 can be discharged along the vent seal seam 13. As shown in fig. 11, after the pressing is stopped, the shape of the vent seal 13 is restored to its original shape, thereby providing a sealing effect, and at this time, the concave hole 12 can be bonded to the surface of the adherend.
