Description

Technical Field

[0001] This utility model belongs to the field of reflective adhesive tape, specifically, it relates to a structure of reflective adhesive tape without a backing paper. Background Technology

[0002] Traditional reflective tape is widely used in road markings, traffic facilities, and vehicle reflective strips. It typically uses polyester film as the base material, combined with glass beads, reflective film, or metallic reflective materials to achieve its reflective effect. However, existing reflective tapes often have structural limitations, particularly in adapting to different lighting environments and enhancing structural sophistication. To address this challenge, innovative reflective tape designs have emerged in recent years, especially those that do not use a backing paper (such as release paper), offering greater convenience and adaptability.

[0003] Traditional reflective tapes mostly protect the adhesive layer by adding a backing paper (release paper), facilitating storage and use. However, this design not only increases material costs but also generates more waste, placing a burden on the environment. Furthermore, the structure of traditional reflective tapes is generally quite simple, lacking sufficient mechanical strength to resist external pressure or tension. Even with the addition of protective layers on the surface, the lack of a proper supporting layer results in poor pressure resistance and tensile strength, making the tape prone to deformation or damage under external forces.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a backing paper-free reflective adhesive tape structure, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A backing-free reflective adhesive tape structure includes: a film roll, the outer surface of which is wound with reflective tape. The reflective tape is composed of a foam layer, a reflective layer, a light-transmitting layer, a mesh layer, an adhesive layer, and a centrifugal silicone oil layer. The reflective layer is bonded above the foam layer, the mesh layer is bonded between the reflective layer and the foam layer, and a combination groove adapted to the mesh layer is opened between the reflective layer and the foam layer. The light-transmitting layer is bonded to the surface of the reflective layer, the adhesive layer is bonded below the foam layer, and a release silicone oil layer is applied below the adhesive layer.

[0008] Optionally, a shear line is provided on the surface above the light-transmitting layer, and a guide groove is provided above the shear line, with the cross-section of the guide groove having a V-shaped structure.

[0009] Optionally, a honeycomb structure is arranged below the foam layer, and the adhesive layer is arranged inside the honeycomb structure.

[0010] Optionally, the shape of the holes of the mesh layer is one of prismatic, rectangular, polygonal, and circular.

[0011] Optionally, the light-transmitting layer group comprises at least one light-transmitting layer, and the light-transmitting layer is one of a transparent pet film layer, a silica sol film, an alumina sol film, and a titanium oxide sol film.

[0012] Optionally, the adhesive layer (2) is one of pressure-sensitive adhesive and composite adhesive, and the thickness of the adhesive layer is 85-100 μm.

[0013] Optionally, the pressure-sensitive adhesive is used when the reflective layer is bonded to the foam layer, the mesh layer, and the light-transmitting layer.

[0014] After the above technical solution is adopted, the present application has the following advantages compared with the prior art, of course, any product implementing the present application does not necessarily need to achieve all the advantages described below:

[0015] 1. The setting of the release silicon oil layer allows the adhesive tape to be used smoothly without the backing paper, which not only reduces the material cost but also reduces the generation of waste and is more friendly to the environment. This design makes the production and application of the adhesive tape more efficient, in line with the trend of modern environmental protection and sustainable development. In addition, the mesh layer provides additional structural support, effectively enhancing the mechanical strength of the reflective adhesive tape. Due to the uniform distribution of the mesh layer, it can uniformly disperse the external pressure, reducing the deformation or breakage of the adhesive tape during use, thereby improving its durability and long-term stability.

[0016] The specific embodiments of the present application will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0026] The present application will now be further described in detail with reference to the accompanying drawings.

[0027] Please refer to Figures 1-4 It is shown that in the present embodiment, a non-paper backing reflective tape structure is provided, which comprises a film tube 1, the outer surface of the film tube 1 is wrapped with a reflective tape, the reflective tape is composed of a foam layer 2, a reflective layer 3, a light transmission layer 4, a mesh layer 5, an adhesive layer 6, and a centrifugal silicone oil layer 7, the reflective layer 3 is bonded above the foam layer 2, the mesh layer 5 is bonded between the reflective layer 3 and the foam layer 2, and a combination groove adapted to the mesh layer 5 is provided between the reflective layer 3 and the foam layer 2, the light transmission layer 4 is bonded to the surface of the reflective layer 3, the adhesive layer 6 is bonded below the foam layer 2, and the release silicone oil layer is applied below the adhesive layer 6. The pressure-sensitive adhesive is used when the reflective layer 3 is bonded to the foam layer 2, the mesh layer 5, and the light transmission layer 4. The shape of the mesh layer 5 hole is one of prismatic, rectangular, polygonal, and circular, and the reflective layer 3 is purchased from the prior art.

[0028] A honeycomb structure is provided below the foam layer 2, and the adhesive layer 6 is located inside the honeycomb. The addition of the mesh layer 5 not only increases the structural stability of the tape, but also provides good air permeability and light scattering effect through the shape of its holes such as prismatic, rectangular, polygonal, or circular, further optimizing the reflective performance.

[0029] In addition, a combination groove is provided between the mesh layer 5 and the foam layer 2, which can effectively combine the layers of materials tightly, enhancing the overall physical stability and durability. The honeycomb structure provided below the foam layer 2 enhances the compressive strength of the tape. The mesh layer 5 can use one of nylon mesh, polyester mesh, and polypropylene mesh.

[0030] Traditional reflective tape usually needs to use release paper to isolate the adhesive layer 6 to prevent the tape from sticking during storage or transportation. However, the release paper usually needs to be discarded after use, which increases the generation of waste and causes certain pollution to the environment. By using the centrifugal silicone oil layer 7, the need for release paper can be eliminated, thereby reducing waste and meeting the trend of green environmental protection.

[0031] The surface above the light transmission layer 4 is provided with a shearing line 8, and a guide groove is arranged above the shearing line 8, and the cross section of the guide groove is in V-shaped structure. The existence of the guide groove can guide the cut adhesive tape more smoothly in the pasting process, and avoids the phenomenon of position deviation or lifting of the adhesive tape in application. The V-shaped cross section design further enhances the stability of the guide groove, ensures the accurate positioning of the adhesive tape, and especially in the complex curved surface or edge position, can more accurately fit the target surface.

[0032] The light transmission layer 4 group includes at least one light transmission layer 4, and the light transmission layer 4 is one of a transparent pet film layer, a silica sol film, an alumina sol film and a titanium oxide sol film.

[0033] The adhesive layer 6 is a pressure-sensitive adhesive, and the thickness of the adhesive layer 6 is 100 mu m.

[0034] The utility model is not limited to the above-mentioned embodiment, anyone should know the structural change made under the inspiration of the utility model, any identical or similar technical scheme with the utility model falls into the protection scope of the utility model. The utility model is not described in detail, and the technical, shape and structure parts are all known technologies.
