[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3 One embodiment of this utility model is a high-temperature resistant double-sided electronic tape, comprising a polyimide layer 9 and an aerogel layer 4, wherein a heat dissipation component is provided on the side of the polyimide layer 9 and a waterproof component is provided on the side of the aerogel layer 4.

[0032] The heat dissipation component includes an alumina layer 8, which is fixedly connected to the side of the polyimide layer 9. The alumina layer 8 is tightly connected to the side of the polyimide layer 9. Alumina has excellent thermal conductivity; when heat is generated during the operation of the electronic device and transferred to the tape, the alumina layer 8 can quickly absorb and conduct the heat. The heat is transferred along a path with high thermal conductivity through lattice vibrations and other means in the alumina layer 8, thereby dissipating the heat from the high-temperature area. A copper foil layer 3 is fixedly connected to the side of the polyurethane foam layer 2, which is fixedly connected to the side of the aerogel layer 4. The copper foil layer 3 connects between the polyurethane foam layer 2 and the aerogel layer 4. Copper has excellent electrical conductivity; when there is external electromagnetic interference, the copper foil layer can reflect and absorb electromagnetic radiation, thus acting as electromagnetic shielding.

[0033] Reference Figure 1 , Figure 2 and Figure 4The waterproof component includes a silicone rubber adhesive 5, which is fixedly connected to the side of the aerogel layer 4. An organosilicon coating layer 6 is fixedly connected to the side of the silicone rubber adhesive 5. The silicone rubber adhesive 5 not only tightly connects the aerogel layer 4 to the organosilicon coating layer 6, but also, because silicone rubber itself has a certain degree of hydrophobicity, it can prevent water penetration to a certain extent.

[0034] Reference Figure 1 and Figure 2 A base layer 1 is fixedly connected to the side of the polyimide layer 9. The base layer 1, connected to the polyimide layer 9, enhances the overall strength of the tape and provides a stable foundation for the adhesion and function of other functional layers. A polyurethane foam layer 2 is fixedly connected to the other side of the base layer 1. The polyurethane foam layer 2 has good cushioning properties and can absorb external impacts. An epoxy resin adhesive 10 is fixedly connected to the side of the alumina layer 8, and a fiberglass paper 11 is fixedly connected to the side of the epoxy resin adhesive 10. The epoxy resin adhesive 10 firmly connects the alumina layer 8 and the fiberglass paper 11. The fiberglass paper 11 not only has a certain degree of insulation, preventing the risk of leakage caused by heat transfer, but also helps the alumina layer 8 further disperse heat and enhances the mechanical strength of the entire heat dissipation structure, making it less prone to damage during heat transfer. A double-sided silicone release paper 7 is fixedly connected to the side of the silicone coating layer 6. When the tape is not in use, the double-sided silicone release paper 7 covers the surface of the silicone coating layer 6, preventing the coating layer from being contaminated and damaged by external factors, ensuring that the waterproof performance is not affected. When using tape, the dual silicone release paper 7 can be easily peeled off.

[0035] Working Principle: The polyimide layer 9 possesses excellent high-temperature resistance and good mechanical properties, providing basic high-temperature resistance and structural support for the entire tape, ensuring the overall stability of the tape in high-temperature environments. The base layer 1 is connected to the side of the polyimide layer 9, further enhancing the basic strength and stability of the tape, ensuring that other functional layers can function effectively. The alumina layer 8 is fixed to the side of the polyimide layer 9. Utilizing the excellent thermal conductivity of alumina, it quickly conducts heat absorbed on one side of the tape away, playing a heat dissipation role and preventing heat accumulation from affecting the tape's performance and the normal operation of the fixed electronic components. The fiberglass paper 11 is connected to the alumina layer 8 through epoxy resin adhesive 10. The fiberglass paper 11 not only has a certain degree of insulation but also enhances the overall structural strength, while assisting the alumina layer 8 in dispersing and transferring heat. The aerogel layer 4 has extremely low thermal conductivity, effectively preventing heat from being transferred to the other side through the tape, achieving good heat insulation while dissipating heat, reducing the impact of heat on electronic components or objects on the other side.

[0036] The silicone rubber adhesive 5 is fixed to the side of the aerogel layer 4, serving two purposes: firstly, it connects the aerogel layer 4 to the silicone coating layer 6; secondly, silicone rubber itself has a certain degree of water resistance. The silicone coating layer 6 further enhances the water resistance; its low surface energy makes it difficult for water to adhere and penetrate, effectively preventing moisture from entering the tape and protecting the internal structure and the fixed electronic components from water damage. The dual-silicone release paper 7 is attached to the side of the silicone coating layer 6, protecting it from external contamination and damage when the tape is not in use, and allowing for easy peeling when needed.

[0037] The polyurethane foam layer 2 is connected to the other side of the base layer 1. It has good cushioning properties and can absorb external impacts, protecting electronic components from vibration and shock. The copper foil layer 3 is connected between the polyurethane foam layer 2 and the aerogel layer 4. Utilizing the good conductivity of copper, it can reflect and absorb electromagnetic radiation, realizing electromagnetic shielding function, preventing external electromagnetic interference from affecting electronic components, and at the same time avoiding leakage of electromagnetic signals generated by internal electronic components.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
