Technical Field
[0001] This utility model relates to the field of aluminum foil tape technology, and in particular to an aluminum foil tape. Background Technology
[0002] Aluminum foil tape is used for sealing seams in all aluminum foil composite materials, sealing punctures in insulation nails, and repairing damaged areas. It is a key raw material for refrigerator and freezer manufacturers and an essential purchase for insulation material distributors.
[0003] When using aluminum foil tape, simply pull and cut the rolled-up tape. However, current aluminum foil tapes have low strength and are easily deformed when pulled. Furthermore, after use, the rolled-up aluminum foil tape often sticks together, making it inconvenient to find or tear later, and sometimes even causing it to break in the middle when pulled. Figure 4 As shown; therefore, this application proposes an aluminum foil tape. Utility Model Content

[0009] Furthermore, the aluminum foil substrate is made of glass fiber, and the glass fiber is arranged in a mesh.
[0010] Furthermore, the first reinforcing layer, the second reinforcing layer, and the aluminum foil substrate are all connected by adhesive, and the adhesive is applied by a roller to the first reinforcing layer and the second reinforcing layer.
[0011] Furthermore, the connecting layer is made of non-stick paper strips, which are equidistantly distributed on the first reinforcing layer.
[0012] Furthermore, the adhesive layer is applied to the second reinforcing layer by means of a roller brush or coating.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention increases the strength of aluminum foil tape by setting a first reinforcing layer and a second reinforcing layer, making it less prone to deformation and damage. The free end of the rolled aluminum foil tape is bonded to the non-stick paper, making it easy to find the free end of the aluminum foil tape and tear it apart later without tearing or breaking, thus facilitating user use.

[0020] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0022] like Figures 1-4 As shown in the figure, this utility model embodiment provides an aluminum foil tape, comprising:
[0023] Paper roll 1;
[0024] Aluminum foil tape 2 is wound onto a paper roll 1. The aluminum foil tape 2 includes a connecting layer 21, a first reinforcing layer 22, an aluminum foil substrate 23, a second reinforcing layer 24, and an adhesive layer 25. The connecting layer 21 is disposed at the upper end of the first reinforcing layer 22, the aluminum foil substrate 23 is disposed at the lower end of the first reinforcing layer 22, the second reinforcing layer 24 is located at the lower end of the aluminum foil substrate 23, and the adhesive layer 25 is disposed at the lower end of the second reinforcing layer 24. The adhesive layer 25 is applied to the second reinforcing layer 24 by a roller or by coating. The first reinforcing layer 22 and the second reinforcing layer 24 can increase the strength of the aluminum foil substrate 23, thereby increasing the strength of the aluminum foil tape 2 and making it less prone to deformation and damage.
[0025] The aluminum foil substrate 23 has multiple through holes 27, so that when the first reinforcing layer 22 and the second reinforcing layer 24 are connected to the aluminum foil substrate 23 by adhesive, the first reinforcing layer 22 and the second reinforcing layer 24 will also be connected to each other, thereby increasing the strength and stability of the connection.
[0026] The first reinforcing layer 22 is made of PET film. PET film has excellent mechanical properties, and its toughness is the best among all thermoplastics. Its tensile strength and impact strength are much higher than those of ordinary films. It also has good stiffness and dimensional stability, which can increase the strength of the aluminum foil substrate 23.
[0027] The second reinforcing layer 24 is made of glass fiber, which is arranged in a mesh pattern to increase the contact area with the adhesive and to better connect with the aluminum foil substrate 23. Glass fiber is a high-performance inorganic non-metallic material with many varieties. Its advantages include good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. Therefore, it can reinforce the aluminum foil substrate 23 on both sides and increase the strength of the aluminum foil substrate 23.
[0028] The first reinforcing layer 22, the second reinforcing layer 24 and the aluminum foil substrate 23 are all connected by adhesive 26. The adhesive 26 is rolled onto the first reinforcing layer 22 and the second reinforcing layer 24. Since the glass fiber is arranged in a mesh, the contact area with the adhesive is larger when the adhesive is rolled, so that it can be more stably connected to the aluminum foil substrate 23.
[0029] The connecting layer 21 is made of non-stick paper strips, which are evenly distributed on the first reinforcing layer 22. This ensures that when the aluminum foil tape 2 is torn, the free end of the rolled-up aluminum foil tape 2 adheres to the non-stick paper, making it easy to locate and tear the free end of the aluminum foil tape 2 without causing it to break. Figure 4 As shown, so that users can use it.
[0030] In summary, this utility model increases the strength of the aluminum foil substrate 23 by setting the first reinforcing layer 22 and the second reinforcing layer 24, thereby increasing the strength of the aluminum foil tape 2 and making it less prone to deformation and damage. The non-stick paper strips are evenly distributed on the first reinforcing layer 22. Thus, when the aluminum foil tape 2 is torn, the free end of the rolled-up aluminum foil tape 2 adheres to the non-stick paper, making it easy to locate and tear the free end of the aluminum foil tape 2 without tearing or breaking. Figure 4 As shown, so that users can use it.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
