UTILITY MODEL CONTENTS
[0004] The utility model discloses a durable anti-static graphite heat dissipation adhesive tape, which has good vertical heat dissipation performance, improves the heat dissipation effect, and the special setting of the adhesive layer part further improves the overall heat dissipation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Reference Figures 1-3 A durable antistatic graphite heat dissipation tape includes a take-up sleeve 2, with a tape body 1 wound around the outside of the take-up sleeve 2, and a release film 12 provided on the upper side of the tape body 1.
[0020] The tape body 1 is composed of a graphite thermally conductive layer 15, a first adhesive layer 14, and a second adhesive layer 16. The graphite thermally conductive layer 15 is made of highly thermally conductive graphite sheet and is located in the middle of the tape body 1, responsible for the main heat dissipation function. The first adhesive layer 14 is located on the upper side of the graphite thermally conductive layer 15, and the second adhesive layer 16 is located on the inner side of the graphite thermally conductive layer 15. The first adhesive layer 14 and the second adhesive layer 16 have the same thickness to ensure the uniformity and stability of the tape during application. Both the first adhesive layer 14 and the second adhesive layer 16 are made of silicone containing carbon nanotubes. The addition of carbon nanotubes significantly improves the electrical and thermal conductivity of the silicone, so that the adhesive layer not only has good adhesion but also excellent heat dissipation performance. Furthermore, antistatic agents are added to the graphite thermally conductive layer 15, the first adhesive layer 14, and the second adhesive layer 16 to improve the overall antistatic effect.
[0021] Among them, the first adhesive layer 14 and the second adhesive layer 16 are embedded with thermally conductive copper mesh. The copper mesh serves as a framework for electrical and thermal conductivity, further enhancing the thermal conductivity and durability of the tape. When the tape is pasted on electronic equipment, the copper mesh can effectively conduct heat from the surface of the equipment to the graphite thermally conductive layer 15, and then the graphite thermally conductive layer 15 can quickly dissipate the heat. The copper mesh can be embedded by pressing, inlaying or weaving processes to ensure a tight bond between the copper mesh and the adhesive layer, and to prevent it from falling off or loosening during use.
[0022] It also includes a lateral heat dissipation prevention mechanism, which is used to reduce the lateral heat dissipation performance of the tape and ensure the overall heat dissipation effect. The lateral heat dissipation prevention mechanism includes rubber layers 13 symmetrically arranged on the front and rear sides of the tape body 1.
[0023] In this invention, firstly, the required length of adhesive tape body 1 is unwound from the take-up sleeve 2, and the tape is cut to a suitable size. After adhering the second adhesive layer 16 to the location requiring heat dissipation, the release film 12 is peeled off, exposing the first adhesive layer 14. The first adhesive layer 14 is then aligned and connected to the heat dissipation device (such as a radiator). Since both the first adhesive layer 14 and the second adhesive layer 16 are composed of silicone containing carbon nanotubes, they not only have good adhesion but also provide excellent heat dissipation performance. The graphite thermally conductive layer 15, as the core of the tape, utilizes its high thermal conductivity to quickly absorb and distribute heat. The heat generated by the equipment is dissipated by the thermally conductive copper mesh in the first adhesive layer 14 and the second adhesive layer 16, which acts as a conductive and thermally conductive skeleton to further enhance the thermal conductivity of the tape. The copper mesh can effectively conduct heat from the surface of the equipment to the graphite thermally conductive layer 15, and then the graphite thermally conductive layer 15 can quickly dissipate the heat. The sealing rubber layers 13 on the front and rear sides of the tape body 1 form a lateral heat dissipation prevention mechanism. Their function is to reduce the lateral heat dissipation performance of the tape and ensure that the heat is mainly conducted along the thickness direction of the tape (i.e., the vertical direction) and directly transferred to the heat sink for heat dissipation, thereby improving the overall heat dissipation efficiency.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
