Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, specifically to stackable high-temperature masking tape rolls. Background Technology

[0002] High-temperature masking tape is a special type of tape designed specifically for high-temperature environments. It is primarily used to protect specific areas from contamination, coatings, or damage during high-temperature processes. Commonly used for high-temperature protection, it can withstand temperatures up to 200°C to 300°C (or even higher), and is suitable for high-temperature processes such as baking, painting, powder coating, and electroplating. It protects sensitive components (such as electronic components and plastic parts) from the effects of hot air or radiation; and during spraying, coating, or chemical treatments, it covers areas that do not require treatment (such as the edges of car windows or solder joints on circuit boards) to ensure work accuracy. It can also temporarily fix parts during high-temperature assembly or welding; the tape remains sticky at high temperatures, preventing it from easily falling off or leaving residue.

[0003] High-temperature masking tape is packaged in rolls and stacked during storage. Existing tape rolls are simply stacked together, relying on gravity to stack them. There is a lack of effective fixing structure between the tape rolls, which makes them prone to loosening and slipping during transportation or storage, resulting in wear or contamination of the tape edges.

[0023] Example

[0024] To address the technical problems in the background section, the following stackable high-temperature masking tape roll is provided:

[0025] Combination Figures 1-4 As shown, the stackable high-temperature masking tape roll provided by this utility model includes a tape inner cylinder 2 and a tape body 1 wrapped around the outer surface of the tape inner cylinder 2.

[0026] The inner tube 2 of the tape includes a limiting groove 22, a tube body 23, and a limiting block 25. One end of the tube body 23 has the limiting groove 22, and the other end extends to form the limiting block 25. The limiting block 25 is connected to the limiting groove 22. To facilitate the insertion of the limiting block 25 into the limiting groove 22 for tape stacking, the longitudinal section of the limiting block 25 is trapezoidal, with the insertion end width smaller than the fixed end width. The limiting groove 22 has a rectangular cross-section. Therefore, when stacking tapes, the limiting block 25 of one tape is aligned with the limiting groove 22 of the tape requiring another tape, allowing the limiting block 25 to be inserted into the limiting groove 22, thus completing the tape stacking.

[0027] To facilitate the tearing and use of the tape, the inner tube 2 of the tape also includes a fixed disc 21 and a rotating shaft 24. The fixed disc 21 is fixed at the center of the tube body 23, and the rotating shaft 24 is rotatably connected to the center of the fixed disc 21. The rotating shaft 24 has an "I" shaped cross-section, and a radial arc-shaped protrusion is provided in the axial central area of ​​the rotating shaft 24. When tearing and using the tape, two fingers can be used to hold the two sides of the rotating shaft 24, and the other hand can pull the movable end of the tape body 1 to make the entire inner tube 2 of the tape rotate the tape body 1, thereby tearing the tape out for use.

[0028] The tape body 1 includes a nano-alumina coating 11, a substrate layer 12, a composite adhesive layer, and a release film layer 17. The substrate layer 12 is formed by twill weaving of silicon carbide fibers, and the thickness of the substrate layer 12 is 25-40 μm. The surface of the substrate layer 12 is coated with nano-alumina to form the nano-alumina coating 11, and the thickness of the nano-alumina coating 11 is 2-5 μm. The bottom end of the substrate layer 12 is pressed to form a micron-level wave pattern 13, and the wave pattern 13 adopts a combination of sine wave and square wave. The composite texture has an amplitude of 10-30 μm and a wavelength of 100-300 μm. The wave pattern 13 compensates for thermal expansion stress, reduces high-temperature warping, and improves the adhesion of the tape. A composite adhesive layer is provided on the other surface of the substrate layer 12. This composite adhesive layer includes an anchoring base adhesive layer 14, a support mesh layer 15, and a functional adhesive layer 16. The bottom end of the anchoring base adhesive layer 14 has a support mesh layer 15 formed by aramid braiding, and the bottom end of the support mesh layer 15 has a functional adhesive layer 16. The thickness of the anchoring base adhesive layer 14 is 5-10 μm, the thickness of the support mesh layer 15 is 5-10 μm, and the thickness of the functional adhesive layer 16 is 10-20 μm. Specifically, the anchoring base adhesive layer 14 uses epoxy-modified silicone. The functional adhesive layer 16 includes pressure-sensitive adhesive, hot melt adhesive, or resin adhesive, but is not limited to these. Boron nitride microspheres are added internally to form thermally conductive channels at high temperatures, preventing localized overheating and delamination. The other surface of the composite adhesive layer is provided with a release film layer 17, which is made of fluorinated release PET film.

[0029] In addition, when there is no high demand for tape, considering cost, the composite adhesive layer can be directly set as a functional adhesive.

[0030] Working principle and usage process of this utility model:

[0031] In this invention, when stacking tapes, the limiting block 25 of one tape is aligned with the limiting groove 22 of the tape to be used, so that the limiting block 25 is inserted into the limiting groove 22, thus completing the stacking of tapes. In use, two fingers can be used to hold the two sides of the rotating shaft 24, and the other hand can be used to pull the movable end of the tape body 1 to make the entire inner tube 2 of the tape rotate the tape body 1, thereby tearing out the tape for use.
