Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, and in particular to a double-sided mesh adhesive tape structure with a separator. Background Technology

[0002] Currently, double-sided tape is commonly used to bond doors (or profiles) to sealing strips (such as PU-coated sealing strips or vulcanized EPDM sealing strips). Double-sided tape typically has two opposing adhesive layers, A and B. The A layer adheres to the sealing strip, and the B layer adheres to the door (or profile). To improve structural strength, existing double-sided tapes usually contain multiple layers, separated by a mesh fabric. Adjacent layers can easily permeate through the mesh. If one layer contains undesirable components from the substrate, these components can easily seep through the mesh to the other layer, potentially damaging the adhesive strength. This can lead to decreased adhesion, failure to bond, detachment, or release kinks, resulting in the double-sided tape failing to meet required adhesion levels during use. Utility Model Content

[0003] The present invention aims to solve the technical problems existing in the prior art. To this end, the present invention proposes an adhesive tape structure.

[0004] The tape structure according to an embodiment of the present invention includes a double-sided release layer, a composite layer, a first adhesive layer, and a first mesh layer. The composite layer, the first adhesive layer, and the first mesh layer are all located on the same side of the double-sided release layer. The first adhesive layer or the composite layer is bonded to a release surface on one side of the double-sided release layer. The first mesh layer is located between the composite layer and the first adhesive layer, wherein:

[0005] The composite layer includes a second adhesive layer, a substrate layer, and a third adhesive layer. The second adhesive layer and the third adhesive layer are respectively bonded to opposite sides of the substrate layer. The substrate layer is used to prevent the second adhesive layer and the third adhesive layer from penetrating each other.

[0006] The tape structure according to the embodiments of this utility model has at least the following beneficial effects:

[0007] 1. By setting a substrate layer between the second and third adhesive layers, the substrate layer can isolate undesirable components of the object being bonded, such as plasticizers, and prevent these substances from passing through the substrate layer into the second or third adhesive layers, thus avoiding a decrease in adhesion or even situations such as failure to adhere, detachment, or release failure. In addition, the substrate layer can also isolate the adhesive layer from the damage caused by ultraviolet rays in sunlight, blocking the damage of ultraviolet rays to the adhesive layer and preventing aging and other defects.

[0008] 2. Because the substrate layer separates the second and third adhesive layers, they do not permeate each other. Since the materials of the objects bonded by the second and third adhesive layers are different, the second and third adhesive layers can be designed with different performance characteristics according to different application scenarios. For example, the second adhesive layer can use ordinary adhesive to reduce costs; the third adhesive layer can use adhesive with special functions, such as adhesive with strong adhesion, high durability, and strong resistance to high and low temperatures, thereby improving the bonding effect and reducing costs.

[0009] In some embodiments, the first mesh layer is made of fiberglass cloth.

[0010] In some embodiments, the substrate layer is made of any one of cotton paper, non-woven fabric, plastic film, or PE / PP / PET / MOPP / BOPP film.

[0011] In some embodiments, the substrate layer is made of white PET film.

[0012] In some embodiments, the double-sided release layer, the first adhesive layer, the first mesh layer, and the composite layer are stacked sequentially. The tape structure further includes a fourth adhesive layer and a second mesh layer. One side of the second mesh layer is bonded to the third adhesive layer, and the other side of the second mesh layer is bonded to the fourth adhesive layer.

[0013] In some embodiments, the material of the second mesh layer is fiberglass cloth.

[0014] In some embodiments, the width of the second adhesive layer, the width of the substrate layer, and the width of the third adhesive layer are all the same.

[0015] In some embodiments, the double-sided release layer is made of PET.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, wherein:

[0019] Figure 2 This is a front view of a double-sided mesh tape structure with a partition layer, according to some other embodiments of the present invention.

[0020] Figure 3 This is a front view of a double-sided mesh tape structure with a partition layer, according to some other embodiments of the present invention. Detailed Implementation

[0021] Reference Figure 1 As shown, this utility model provides a double-sided mesh tape structure with a separator, which includes a double-sided release layer, a composite layer, a first adhesive layer, and a first mesh layer.

[0022] The composite layer includes a second adhesive layer, a substrate layer, and a third adhesive layer. The second and third adhesive layers are bonded to opposite sides of the substrate layer, and the substrate layer prevents the second and third adhesive layers from penetrating each other. Both sides of the double-sided release layer are coated with release agent, making both sides release surfaces. The composite layer, the first adhesive layer, and the first mesh layer are all located on the same side of the double-sided release layer. Figure 1 As shown, the third adhesive layer of the composite layer can be bonded to the release surface of one side of the double-sided release layer, one side of the first mesh layer can be bonded to the second adhesive layer, and the other side of the first mesh layer can be bonded to the first adhesive layer. Alternatively, as... Figure 2 As shown, it can also be that the first adhesive layer is bonded to the release surface of one side of the double-sided release layer, one side of the first mesh layer is bonded to the second adhesive layer, and the other side of the first mesh layer is bonded to the first adhesive layer. Figure 1 and Figure 2 In this process, the first mesh layer is located between the composite layer and the first adhesive layer, and the first mesh layer is mainly used to strengthen the structural strength of the tape.

[0023] like Figure 1 As shown, when the double-sided mesh tape structure is in a wound state (the double-sided mesh tape structure is in an unused state), the double-sided mesh tape structure is wound around the outer circumference of the cylinder. The first adhesive layer located in the inner layer of the cylinder is directly bonded to the outer circumferential wall of the cylinder, and the first adhesive layer located in the outer layer of the cylinder is bonded to the release surface on the lower side of the double-sided release layer, allowing the double-sided release layer and the first adhesive layer to be separated. Similarly, for... Figure 2 In one embodiment, the third adhesive layer is bonded to the cylinder and the release surface on the underside of the double-sided release layer, while for... Figure 3 In another embodiment, the fourth adhesive layer is bonded to the cylinder and the release surface on the underside of the double-sided release layer, which will not be described in detail here.

[0024] When using double-sided mesh tape, first tear off the double-sided mesh tape structure, then peel off the double-sided release layer to expose the first or third adhesive layer (for...). Figure 2 and Figure 3 In one embodiment, the first adhesive layer is exposed, while for... Figure 1In one embodiment, the third adhesive layer is exposed, then the first adhesive layer (or the third adhesive layer) is bonded to the sealing strip, and the third adhesive layer (or the first adhesive layer and the fourth adhesive layer) is bonded to the door (or profile), thereby fixing the sealing strip to the door (or profile). Of course, the double-sided mesh tape structure of this embodiment can also be used to bond and fix other objects.

[0025] Existing composite tapes generally suffer from the following problems:

[0026] Existing technologies use substrates such as mesh fabric, which can increase the strength of the adhesive layer, but cannot isolate undesirable components of the substrate, such as plasticizers, from entering the adhesive layer, damaging the adhesive's tackiness, and causing issues such as failure to adhere, detachment, or release failure. Furthermore, they cannot isolate the adhesive layer from the damaging effects of ultraviolet rays from sunlight, leading to aging and other defects.

[0027] Because existing technologies use substrates such as mesh fabric, the adhesives can penetrate each other, and only one type of adhesive can be used on both sides of the substrate. This makes it impossible to apply different adhesives to both sides of the double-sided adhesive, failing to meet the adhesion requirements of customers in the market and frequently resulting in bonding failure. The performance design of the double-sided adhesive layer in this invention can comprehensively solve the above problems.

[0028] It should be noted that, for the double-sided mesh tape structure of this embodiment, the substrate layer is a solid material. The substrate layer can be made of any of the following materials: cotton paper, non-woven fabric, plastic film, PE film, PP film, PET film, MOPP film, and BOPP film. The function of the substrate layer is to separate the second and third adhesive layers, thereby preventing them from penetrating each other. It can also isolate any undesirable components of the substrate on either adhesive layer, such as plasticizers, preventing these substances from penetrating through the substrate layer into the interior of the second or third adhesive layer and damaging the adhesive properties, leading to decreased adhesion or even failure to adhere, detachment, or release folding. Furthermore, the substrate layer can also strengthen the structural strength of the composite layer.

[0029] It should also be noted that, since the substrate layer separates the second and third adhesive layers, the second and third adhesive layers will not permeate each other. Because the materials of the objects bonded by the second and third adhesive layers are different, the second and third adhesive layers can be designed with different performance characteristics according to different application scenarios. For example, the second adhesive layer can use ordinary adhesive to reduce costs; the third adhesive layer can use adhesive with special functions, such as adhesive with strong adhesion, high durability, and strong resistance to high and low temperatures, thereby improving the bonding effect and reducing costs.

[0030] In some embodiments, the first mesh layer can be made of fiberglass cloth, PET, nylon, or other materials. This can improve the structural strength.

[0031] In some embodiments, the substrate layer is made of white PET film, which has a high opacity and can block ultraviolet rays from damaging the adhesive layer, preventing aging and other defects. In other embodiments, the substrate layer can be other colors or even transparent.

[0032] like Figure 3 As shown, in some embodiments, the double-sided release layer, the first adhesive layer, the first mesh layer, and the composite layer are stacked sequentially from bottom to top. The tape structure also includes a fourth adhesive layer and a second mesh layer. One side of the second mesh layer is bonded to the third adhesive layer, and the other side of the second mesh layer is bonded to the fourth adhesive layer. This embodiment, by setting two mesh layers, can further improve the structural strength of the tape.

[0033] In some embodiments, the second mesh layer can be made of fiberglass cloth, or other materials such as PET or nylon. This can improve the structural strength.

[0034] In some embodiments, the widths of the second adhesive layer, the substrate layer, and the third adhesive layer are all the same. This can be understood as the second and third adhesive layers being fully coated relative to the substrate layer, maximizing their area and thus improving the bonding and fixing effect of the composite layer. If the width of the substrate layer is smaller than the widths of the second and third adhesive layers, the thinner substrate layer may be more prone to cracking during manufacturing.

[0035] In some embodiments, the double-sided release layer can be made of PET, which has good structural strength and is not easily broken during the peeling process.
