Description

Technical Field

[0001] This utility model relates to the field of industrial tape technology, specifically a PET-based high-temperature resistant tape. Background Technology

[0002] PET-based high-temperature resistant tape is a type of tape made of polyester film as the base material and coated with a special high-temperature resistant adhesive. It is specifically designed to maintain its adhesion, insulation and physical properties in high-temperature environments.

[0003] Traditional high-temperature resistant tapes only focus on heat insulation and cannot simultaneously address electromagnetic interference or structural support requirements. To achieve these effects, users need to layer multiple tapes, leading to increased thickness and decreased bonding reliability. Some multi-layer composite tapes are difficult to peel off, and uneven interlayer adhesion often causes breakage during peeling, affecting the reuse of functional layers. Therefore, we propose a PET-based high-temperature resistant tape. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a PET-based high-temperature resistant tape, which solves the problem of needing to stack multiple tapes to meet electromagnetic interference or structural support requirements, resulting in increased thickness and decreased bonding reliability. It also solves the problem of difficult interlayer peeling of multi-layer composite tapes, which affects the reuse of functional layers.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a PET-based high-temperature resistant tape, comprising, from the outside to the inside, a grid-reinforced PET release film layer, a low-density polyethylene porous film layer, a modular functional substrate layer, and a silicone dot matrix coated PP film layer.

[0006] The modular functional substrate layer includes a PI film layer, an aluminum foil shielding layer, and a PET substrate layer stacked sequentially.

[0007] Both sides of the grid-reinforced PET release film layer are provided with extension layers;

[0008] The extension layer encapsulates the low-density polyethylene porous membrane layer, the modular functional substrate layer, and the silicone dot matrix coated PP membrane layer.

[0009] Preferably, the low-density polyethylene porous membrane layer has a sixth tear line evenly spaced on it, and a second separation line is provided on both sides of the low-density polyethylene porous membrane layer. The two ends of the sixth tear line are connected to the second separation line to achieve whole-piece tearing and cutting.

[0010] Preferably, the PI film layer has a seventh tear line evenly spaced, and the PI film layer has a third separation line on both sides. The two ends of the seventh tear line are connected to the third separation line to achieve independent tearing and cutting.

[0011] Preferably, the aluminum foil shielding layer has an eighth tear line at equal intervals, and the aluminum foil shielding layer has a fourth separation line on both sides. The two ends of the eighth tear line are connected to the fourth separation line to realize the customized cutting of the electromagnetic shielding sticker.

[0012] Preferably, the PET substrate layer has a ninth tear line evenly spaced, and the PET substrate layer has a fifth separation line on both sides. The two ends of the ninth tear line are connected to the fifth separation line to realize the segmented use of the mechanical reinforcement layer.

[0013] Preferably, the silicone dot matrix coated PP film layer has tenth tear lines evenly spaced on it to support repeated application and partial replacement of the protective layer.

[0014] Preferably, the mesh-reinforced PET release film layer has a first tear line, a second tear line, a third tear line, a fourth tear line and a fifth tear line, and a first separation line is provided on both sides of the mesh-reinforced PET release film layer. The two ends of the first tear line, the second tear line, the third tear line, the fourth tear line and the fifth tear line are connected to the first separation line.

[0015] Preferably, the first tear line, the second tear line, the third tear line, the fourth tear line and the fifth tear line are respectively set to the sixth tear line, the seventh tear line, the eighth tear line, the ninth tear line and the tenth tear line, providing visual guidance for layered truncation.

[0016] Its beneficial effects are as follows:

[0017] 1. This PET-based high-temperature resistant tape features a grid-reinforced PET release film layer to protect the adhesive layer. This layer can be directly peeled off to quickly expose the bonding surface. A low-density polyethylene porous film layer, after lifting the edges, can be peeled off entirely to isolate the adhesive layer from the substrate and prevent contamination of the functional layer. In the modular functional substrate layer, a PI film layer serves as a separate 300℃ heat insulation pad, an aluminum foil shielding layer is cut to serve as an electromagnetic shielding sticker, and the PET substrate layer provides a mechanically reinforced support. The combination of the PI film layer, aluminum foil shielding layer, and PET substrate layer allows a single tape to simultaneously meet the requirements for high-temperature protection, signal shielding, and structural support, reducing material stacking during equipment assembly. A silicone dot matrix coated PP film layer is directly pasted on as pre-construction protection and can be repeatedly applied for temporary covering. When in use, the silicone dot matrix coated PP film layer is peeled off to expose the modular functional substrate layer.

[0018] 2. This PET-based high-temperature resistant tape, through the extension layer, makes the mesh-reinforced PET release film layer, low-density polyethylene porous film layer, modular functional substrate layer and silicone dot matrix coated PP film layer have strong integrity. The wrapping design of the extension layer not only ensures the overall structural strength, but also allows for the sequential removal of each layer during construction through disassembly of the extension, making the operation logic clear.
