[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figs. 1-3 The utility model provides a kind of technical solutions: a kind of residueless adhesive tape, including base material layer 1, the top surface of base material layer 1 is provided with first release paper 2, and the bottom surface of base material layer 1 is provided with barrier strip 3 at equal intervals, and the bottom surface of base material layer 1 is provided with adhesive layer 4 between two groups of barrier strip 3, and the bottom surface of adhesive layer 4 is provided with second release paper 5.

[0020] The base material layer 1 is a polyimide film layer.

[0021] The top surface of base material layer 1 is provided with through groove 6 at equal intervals, and through groove 6 corresponds to each group of adhesive layer 4.

[0022] The barrier strip 3 is arranged as a polyethylene strip, and the barrier strip 3 is arranged as a continuous bending structure.

[0023] The adhesive layer 4 is arranged as a sand-adjusting glue layer.

[0024] The top surface of the first release paper 2 and the bottom surface of the first release paper 2 are both provided with a silicon oil coating.

[0025] Working principle: firstly, when a section of the adhesive tape is cut off for use, the second release paper 5 needs to be removed first, and then the adhesive tape is pasted on the surface of the object by the adhesion of the adhesive layer 4, wherein the barrier strip 3 arranged on the bottom surface of the substrate layer 1 as a continuous bending structure can prevent the adhesive layer 4 from being adhered together due to the bending of the adhesive tape during the removal of the second release paper 5, improve the structural property of the adhesive tape, avoid the soft couch phenomenon, and at the same time, the interval arrangement can ensure that the adhesive tape is pasted on the surface of the object.

[0026] Then, when the adhesive tape needs to be torn off, the first release paper 2 can be removed, and the top surface of the substrate layer 1 is wiped with water. Since the adhesive layer 4 is a sand-adjusting glue layer, after the water penetrates into the corresponding adhesive layer 4 through the through groove 6, the adhesive layer 4 can absorb water and reduce its adhesion due to its material properties. Therefore, when the adhesive tape is removed, the no-residue effect can be achieved, so as to ensure the adhesion of the adhesive tape during normal use while achieving the no-residue effect.
