[0022] A high-temperature resistant double-sided electronic tape provided by the present application includes a tape rack 1; a tape body 2 is arranged on the outer side of the tape rack 1, and a high-temperature resistant mechanism 3 is arranged on the inner side of the tape body 2;

[0023] The high-temperature resistant mechanism 3 includes a polyimide layer 301, a PP glue 302, a polyester film 303 and a heat insulation film 304. The PP glue 302 is arranged on the inner side of the polyimide layer 301, and the polyester film 303 is adhesively installed on the inner side of the polyimide layer 301 through the PP glue 302, and the heat insulation film 304 is adhesively installed on the inner side of the polyester film 303 through the polyester film 303;

[0024] Specifically, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, when the device is in use, due to the excellent high-temperature resistance of the polyimide layer 301 itself, it can maintain stable performance in a wide temperature range from -269°C to 400°C. Coupled with the fact that the polyester film 303 itself not only has a very high tensile strength and good elasticity, can withstand large mechanical stresses, but also has good heat resistance and can be used at higher temperatures, and at the same time has good cold resistance and can maintain its performance unchanged in a low-temperature environment. By using the PP glue 302 to fixedly bond the polyimide layer 301, the polyester film 303 and the heat insulation film 304 into a whole, it can further improve the high-temperature resistance and wear resistance of the tape body 2, and increase the service life of the tape substrate.

[0025] Further, a base adhesive 8 is provided on the surface of the tape body 2. The tape body 2 is adhesively installed with a release paper 9 through the base adhesive 8. A buffer mechanism 4 is provided on the outer side of the polyimide layer 301. A flame retardant layer 5 is provided on the outer side of the buffer mechanism 4. The buffer mechanism 4 includes a polyurethane foam film 401, PP adhesive II 402, and a polyethylene foam layer 403. The PP adhesive II 402 is provided on the inner side of the polyurethane foam film 401. The polyethylene foam layer 403 is adhesively installed on the polyurethane foam film 401 through the PP adhesive II 402. The flame retardant layer 5 is adhesively installed on the outer side of the polyurethane foam film 401. An antistatic agent layer 6 is adhesively installed on the outer side of the flame retardant layer 5. An insulating layer 7 is adhesively installed on the outer side of the antistatic agent layer 6;

[0026] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, when the tape body 2 is in use, the insulating layer 7 can be used to improve the insulation effect of the tape body 2. At the same time, the polyurethane foam film 401, PP adhesive II 402, and polyethylene foam layer 403 effectively improve the shock absorption protection performance, high temperature resistance performance, and antistatic performance of the tape body 2. In particular, the antistatic agent layer 6 is used to provide double-layer antistatic protection for the tape body 2. At the same time, the setting of the flame retardant layer 5 can further improve the device's ability to provide flame retardant protection for the bottom of the tape body 2, thereby being able to improve the service life of the tape body 2 to a certain extent.

[0027] Working principle: Due to the excellent high temperature resistance of the polyimide layer 301 itself, it can maintain stable performance within a wide temperature range from -269°C to 400°C. Coupled with the fact that the polyester film 303 itself not only has a very high tensile strength and good elasticity, can withstand large mechanical stresses, but also has good heat resistance and can be used at relatively high temperatures, and also has good cold resistance and can maintain its performance unchanged in low temperature environments. The polyurethane foam film 401, PP adhesive II 402, and polyethylene foam layer 403 effectively improve the shock absorption protection performance, high temperature resistance performance, and antistatic performance of the tape body 2. In particular, the antistatic agent layer 6 is used to provide double-layer antistatic protection for the tape body 2. At the same time, the setting of the flame retardant layer 5 can further improve the device's ability to provide flame retardant protection for the bottom of the tape body 2, thereby being able to improve the service life of the tape body 2 to a certain extent.

[0028] Finally, it should be noted that: The above specific embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified and equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
