Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0023] Please refer to Figs. 1 to 3 In the embodiment, the high-thermal-conductivity copper foil adhesive tape comprises an adhesive tape main body 1, the outer part of the adhesive tape main body 1 is provided with a positioning structure for positioning the copper foil adhesive tape, and the adhesive tape main body 1 is provided with a protective layer 7 for protecting the copper foil adhesive tape.

The cylinder 9 and the positioning clasp 12 are both provided with a positioning hole 13, and the positioning rod 14 is inserted into the positioning hole 13, so as to facilitate disassembly and assembly of the adhesive tape main body 1.
[0025] Specifically, the cylinder 9 is provided with a positioning hole 13 matched with the positioning rod 14.
[0026] In the embodiment, the protective layer 7 comprises a waterproof layer 701, a scratch-resistant layer 702 and an oxidation protection layer 703. The oxidation protection layer 703 is installed above the copper foil layer 6, providing additional protection between the copper foil and the heat-conducting layer 5. The copper foil layer 6 is directly protected from the erosion of the external environment. The scratch-resistant layer 702 is installed on the outer surface of the wear-resistant layer 2 to improve the scratch resistance of the adhesive tape. The waterproof layer 701 is installed on the outermost layer of the adhesive tape main body 1 to prevent water from penetrating into the adhesive tape, further prolonging the service life of the adhesive tape.
[0027] Specifically, the waterproof layer 701 is made of polyethylene (PE) or polyvinyl chloride (PVC): these materials have good waterproof performance, which can effectively prevent water from penetrating into the inside of the tape, thereby protecting the internal heat-conducting layer and copper foil layer from moisture erosion. Polyurethane (PU): polyurethane coating not only has waterproof performance, but also has a certain elasticity, which can increase the flexibility and durability of the tape. Fluororubber: fluororubber has excellent chemical corrosion resistance and waterproof performance, suitable for application in extreme environments. The material of the scratch-resistant layer 702 is polycarbonate (PC): polycarbonate has high strength and scratch resistance, commonly used in the production of mobile phone screens and other products that require high wear resistance. Polyethylene terephthalate (PET): PET material also has good wear resistance and scratch resistance, and the cost is relatively low. Polyurethane (PU) coating: in addition to waterproof, polyurethane coating can also provide additional wear and scratch protection. Benefits: the scratch-resistant layer 702 can protect the tape from physical damage such as scratches and wear, thereby maintaining its appearance and performance. The material of the oxidation protection layer 703 is silicone coating: silicone coating can form a dense protective film, effectively preventing the copper foil layer from oxidizing and corroding. Epoxy resin: epoxy resin has excellent adhesion and corrosion resistance, which can tightly adhere to the surface of the copper foil layer 6, providing long-term protection. Metal oxide film: such as aluminum oxide or silicon dioxide film, these films have extremely high chemical stability and corrosion resistance, which can effectively prevent the copper foil layer from reacting with oxygen and water vapor in the air. Benefits: the oxidation protection layer can ensure that the copper foil layer 6 maintains its electrical conductivity and thermal conductivity during long-term use, preventing performance degradation due to oxidation.
[0028] In this embodiment, the outer surface of the copper foil layer 6 is coated with adhesive, which is set to facilitate the adhesion of the copper foil layer 6 to the desired position.
[0029] In this embodiment, the adhesive tape body 1 is provided with a tear groove 8; the opening of the tear groove 8 can achieve the effect of quickly tearing when using the adhesive tape body 1. When using, after the adhesive tape body 1 is adhered to the position required to be adhered, the two hands are placed on both sides of the tear groove 8, and the adhesive tape body 1 is torn through the tear groove 8. The material of the wear-resistant layer 2 is organic glass film. The material of the heat-resistant layer 4 is high-temperature-resistant soft rubber. The materials of the heat-conducting layer 5 and the reinforcing layer 3 are both carbon fiber. The setting of the wear-resistant layer 2 can increase the wear resistance of the adhesive tape body 1. The setting of the reinforcing layer 3 can increase the strength of the adhesive tape body 1 so that it is not easy to break. The setting of the heat-resistant layer 4 can improve the heat resistance of the adhesive tape body 1. The setting of the heat-conducting layer 5 improves the heat conductivity of the adhesive tape body 1, thereby increasing the practicality of the adhesive tape body 1 and prolonging the service life of the adhesive tape body 1. The adhesive tape body 1 synchronously improves the strength, wear resistance, heat conductivity and high-temperature resistance. In the process of use, the wear-resistant layer 2 can cope with external scratches. The reinforcing layer 3 can increase the strength of the adhesive tape body 1 when it is subjected to external force pulling, so as to avoid its breakage. The heat-resistant layer 4 can improve the high-temperature resistance of the adhesive tape body 1 when it is subjected to high temperature. The heat-conducting layer 5 efficiently conducts heat when the adhesive tape body 1 receives heat.
[0030] Specifically, the adhesive tape body 1 is composed of a wear-resistant layer 2, a reinforcing layer 3, a heat-resistant layer 4, a heat-conducting layer 5 and a copper foil layer 6, which are sequentially laminated.
[0031] In this embodiment, the outer part of the adhesive tape body 1 is provided with a protection structure, which includes a cylinder 9, a protection disc 10 and a scraping strip 11. The scraping strip 11 is slidingly connected to both sides of the adhesive tape body 1. The number of the protection disc 10 is two, and the two protection discs 10 are installed at both ends of the cylinder 9. The number of the scraping strip 11 is four, and the four scraping strips 11 are symmetrically installed on the opposite side of the two protection discs 10. The material of the protection disc 9 is plastic. The material of the scraping strip 10 is rubber. By setting the protection structure, the dust on both sides of the adhesive tape body 1 can be scraped during use, and the wound adhesive tape body 1 can be protected. One of the two protection discs 10 is fixed at one end of the cylinder 9, and the other is sleeved and installed on the outer surface of the other end of the cylinder 9 and is fixed by a positioning structure.
[0032] The working principle of the above embodiment is as follows:
[0033] Through the setting of the wear-resistant layer 2, the reinforcing layer 3, the heat-resistant layer 4, the heat-conducting layer 5 and the copper foil layer 6, the scratch resistance, the strength, the high-temperature resistance and the heat conductivity of the adhesive tape body 1 can be increased. Through the setting of the tear groove 8, the effect of quick tearing can be achieved without using cutting tools such as scissors. The heat conductivity of the adhesive tape body 1 is increased, and its high-temperature resistance, strength and wear resistance are also increased. The practicality is increased, and the service life of the adhesive tape body 1 is prolonged.
[0034] In addition, by setting the protective layer 7 on the adhesive tape body 1, in use, the oxidation protection layer 703 can directly protect the copper foil layer 6 from the erosion of the external environment, the waterproof layer 701 can prevent moisture from penetrating into the inside of the adhesive tape, further prolonging the service life of the adhesive tape, and a harder scratch-resistant layer is added on the wear-resistant layer 2 to improve the scratch resistance of the adhesive tape, especially in application scenarios that require frequent contact or friction, to improve the protection effect of the adhesive tape body 1.
