Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to a hot-melt adhesive tape which can be used repeatedly. Background Art

[0002] Hot melt tape is a type of solvent-free, pollution-free environmentally friendly adhesive tape, which is becoming more and more popular and has been widely used in industrial sectors such as shoemaking, packaging, wood processing, automobiles, textiles, electromechanics, aerospace, etc. Conventional hot melt adhesive only has bonding properties. When used, it only needs to be placed on the surface of the adherend, fixed in position, and then heated and pressurized to achieve bonding properties. Existing hot melt tapes still have the following shortcomings:

[0003] For example, Chinese patent authorization publication number CN202186964U, published on April 11, 2012, discloses a hot-melt adhesive double-sided tape. The hot-melt adhesive tape has a relatively poor adhesive ability and is damaged after one use and cannot be used again, which is a great waste of resources and causes a large amount of tape loss, making it inconvenient for people to use. In addition, the release film on the surface is difficult to tear off, which is inconvenient for people to use in daily life.

[0004] So we propose a reusable hot melt adhesive tape to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a reusable hot melt adhesive tape to solve the problem that the hot melt adhesive tape on the market currently cannot be repeatedly pasted and the release film on the surface is difficult to tear off.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a reusable hot-melt tape, comprising a tape body and cutting teeth, wherein a first release film is arranged on both sides of the tape body, a second release film is arranged at one end of the first release film, and cutting teeth are arranged on one side of the tape body.

[0007] Preferably, the tail end of the first release film is in contact with the head end of the second release film, and both the head ends of the first release film and the second release film are provided with tear heads to ensure that the adhesive part of the tape can be fully protected to avoid affecting the subsequent use of the tape.

[0008] Preferably, the cutting teeth are V-shaped and are evenly distributed on one side of the tape body. The positions of the cutting teeth correspond to the connection positions of the first release film and the second release film, which is helpful for people to separate the tape. The structure is simple and convenient for people to use in daily life.

[0009] Preferably, the tape body includes a hot melt adhesive layer, a nano adhesive layer and flow holes, and the surface of the hot melt adhesive layer is provided with a nano adhesive layer, and the surface of the nano adhesive layer is provided with flow holes to protect the internal hot melt adhesive and prevent the hot melt adhesive from being all adhered to the adhesive at one time, thereby avoiding affecting the subsequent adhesive effect of the tape.

[0010] Preferably, the flow holes are cylindrical in structure, and are distributed in a rectangular array on the surface of the nano-adhesive layer, and the nano-adhesive layer is symmetrically arranged with respect to the hot-melt adhesive layer, so that the hot-melt adhesive can be in uniform contact with the adhered object, ensuring the firmness of the adhesion and improving the practicality of the tape.

[0011] Preferably, the hot melt adhesive layer is made of polyethylene, and the hot melt adhesive layer is wrapped inside by the nano adhesive layer, which has the advantages of being environmentally friendly, non-toxic, odorless and degradable, ensuring the safe use of the tape.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The reusable hot melt adhesive tape is provided with a nano adhesive layer, which is resistant to high temperature and can protect the internal hot melt adhesive to prevent the hot melt adhesive from contacting the adhesive object. The surface of the nano adhesive layer is provided with flow holes for facilitating the flow of the hot melt adhesive, ensuring that the melted hot melt adhesive can flow out evenly and ensure the firmness of the adhesive. At the same time, the tape can be repeatedly torn off and re-adhered by melting the internal hot melt adhesive multiple times, effectively reducing the loss of the tape.

[0014] 2. The surface of the reusable hot-melt adhesive tape is provided with a first release film and a second release film, and the adjacent release films are adhered to each other, and the head ends of the first release film and the second release film are provided with tearing heads, so that people can tear off the release films on the surface conveniently during use, and the operation is simple.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides a technical solution: a reusable hot melt adhesive tape, comprising an adhesive tape body 1 and cutting teeth 4, the adhesive tape body 1 comprising a hot melt adhesive layer 101, a nano adhesive layer 102 and a flow hole 103, and the surface of the hot melt adhesive layer 101 is provided with the nano adhesive layer 102, the hot melt adhesive layer 101 is made of polyethylene, and the hot melt adhesive layer 101 is wrapped inside by the nano adhesive layer 102, so as to prevent the hot melt adhesive from contacting with the adhesive object completely, and prevent the adhesive effect from being reduced when the subsequent adhesive tape is repeatedly pasted;

[0021] The surface of the nano adhesive layer 102 is provided with flow holes 103, which are cylindrical structures and are distributed in a rectangular array on the surface of the nano adhesive layer 102. The nano adhesive layer 102 is symmetrically arranged with respect to the hot melt adhesive layer 101, ensuring that both sides of the tape can be pasted, which is convenient for people to use in daily life and improves the practicality of the tape. The first release film 2 is arranged on both sides of the tape body 1, and the second release film 3 is arranged at one end of the first release film 2.
