[0002] Fiber tape is made of PET as the base material, with reinforced polyester fiber lines inside and coated with special pressure-sensitive adhesive. Fiber tape has excellent wear resistance and moisture resistance, strong breaking strength, and the unique pressure-sensitive adhesive layer has excellent long-lasting adhesion and special properties, making it widely used.

[0003] For example, the Chinese patent document with publication number CN202030695U, the patent name is A glass fiber tape, which mentions "including a surface layer, the surface layer is connected to a first adhesive layer, the first adhesive layer is connected to a glass fiber layer, the glass fiber layer is connected to a second adhesive layer, and the second adhesive layer is connected to a protective layer. The surface layer and the protective layer are glossy paper, and are both made of smooth anti-sticking materials. The first adhesive and the second adhesive are hot melt adhesives.

[0030] In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more than two. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] In one embodiment of the present invention, Figure 1-5 As shown, a high temperature resistant fiber tape is provided, including a central roll 10 and a tape body 20. The tape body 20 is arranged on the central roll 10. The tape body 20 includes an adhesive layer 21, a base layer 22, a reinforcing layer 23, a heat dissipation layer 26 and a high temperature resistant layer 24. The adhesive layer 21 is arranged on the bottom surface of the base layer 22. The reinforcing layer 23 is arranged on the top surface of the base layer 22. The heat dissipation layer 26 is arranged on the top surface of the reinforcing layer 23. The high temperature resistant layer 24 is arranged on the top surface of the heat dissipation layer 26. A wear-resistant layer 25 is arranged on the top surface of the high temperature resistant layer 24. The high temperature resistant layer 24 includes a first high temperature resistant layer 241 and a second high temperature resistant layer 242. The first high temperature resistant layer 241 is arranged on the top surface of the reinforcing layer 23. The second high temperature resistant layer 242 is arranged on the top surface of the first high temperature resistant layer 241, and a high temperature resistant film 243 is arranged on the top surface of the second high temperature resistant layer 242, and the high temperature resistant film 243 is connected to the wear-resistant layer 25.

[0032] In this embodiment, the wear-resistant layer 25 is a nylon material layer, so that the tape body 20 has high strength and wear resistance, and can effectively protect the surface of the fiber tape from wear and scratches.

[0033] By providing a reinforcing layer 23, the overall strength and toughness of the tape body 20 are enhanced, and the use strength of the fiber tape is improved. By providing a heat dissipation layer 26 and a high temperature resistant layer 24, the tape body 20 has good heat dissipation and high temperature resistance effects, thereby improving the service life of the fiber tape. At the same time, by providing a first high temperature resistant layer 241, a second high temperature resistant layer 242 and a high temperature resistant film 243, the high temperature of the outside world is weakened one by one, the heat resistance of the tape body 20 is enhanced, the connection between the inside of the tape body 20 is more stable, and its use stability in a high temperature environment is improved.

[0034] Preferably, the first high temperature resistant layer 241 is a polytetrachloroethylene layer, and the thickness of the first high temperature resistant layer 241 is 15 μm-20 μm. By providing the first high temperature resistant layer 241 of polytetrachloroethylene, polytetrachloroethylene has good high temperature resistance and can remain stable in a high temperature environment, thereby preventing the internal bonding failure of the tape body 20 due to excessive temperature, and ensuring that the internal connection of the tape body 20 is more secure.

[0035] Furthermore, the second high temperature resistant layer 242 is an aluminum foil layer, and the thickness of the second high temperature resistant layer 242 is 15 μm-20 μm. By providing the second high temperature resistant layer 242 of aluminum foil, the aluminum foil layer has a high high temperature resistance and can withstand higher temperatures, so that the fiber tape can still maintain stability and reliability in a high temperature environment, avoiding the internal bonding failure of the tape body 20 due to excessive temperature, and ensuring that the internal connection of the tape body 20 is more secure.

[0036] Furthermore, the thickness of the first high temperature resistant layer 241 is greater than the thickness of the second high temperature resistant layer 242. The high temperature resistant film 243 is a polyimide film, and the thickness of the high temperature resistant film 243 is 10 μm. By providing the high temperature resistant film 243, the high temperature resistance of the tape body 20 is further improved, and the heat is gradually weakened by the first high temperature resistant layer 241, the second high temperature resistant layer 242 and the high temperature resistant film 243, so that the influence of heat on the inside of the tape is minimized, ensuring that the internal connection of the tape body 20 is more firmly secured.

[0037] Furthermore, the heat dissipation layer 26 is a nano-carbon material layer, and the heat dissipation layer 26 is 20 μm-25 μm. By providing the heat dissipation layer 26, the heat transferred from the adhesive to the fiber tape is dissipated through the heat dissipation layer 26, so as to avoid the temperature inside the tape body 20 being too high, effectively prevent the internal bonding failure caused by the high temperature inside the tape body 20, and ensure that the internal connection of the tape body 20 is more secure.

[0038] Preferably, the reinforcing layer 23 includes a glass fiber layer 231 and a polyester fiber layer 232. The glass fiber layer 231 is disposed on the top surface of the base layer 22. The polyester fiber layer 232 is disposed on the top surface of the glass fiber layer 231 and is connected to the heat dissipation layer 26. By providing the glass fiber layer 231 and the polyester fiber layer 232, the reinforcing layer 23 has good tensile strength and toughness, enhances the overall strength of the tape body 20, and improves the service life of the fiber tape.

[0039] Furthermore, the top surface of the glass fiber layer 231 is provided with a plurality of groups of first reinforcing strips distributed equidistantly, and the plurality of groups of first reinforcing strips are arranged horizontally. The bottom surface of the polyester fiber layer 232 is provided with a plurality of groups of second reinforcing strips distributed equidistantly, and the plurality of groups of second reinforcing strips are arranged vertically. The first reinforcing strips are arranged crosswise with the second reinforcing strips. In this embodiment, the first reinforcing strips and the second reinforcing strips are arranged crosswise to form a mesh structure or a "well" structure. Such a structure makes the structure of the reinforcing layer 23 more solid and reliable, and is not easy to be pulled and broken, thereby increasing the service life of the fiber tape.

[0040] Preferably, an antistatic layer 27 is provided between the base layer 22 and the reinforcing layer 23. The top and bottom surfaces of the antistatic layer 27 are provided with a plurality of groups of first convex blocks 31 distributed at equal intervals. The base layer 22 and the reinforcing layer 23 are provided with a plurality of first grooves corresponding to the first convex blocks 31, and the first convex blocks 31 are snap-connected with the first grooves. The top surface of the adhesive layer 21 is provided with a plurality of groups of second convex blocks 32 distributed at equal intervals. The bottom surface of the base layer 22 is provided with a plurality of groups of second grooves corresponding to the second convex blocks 32, and the second convex blocks 32 are snap-connected with the second grooves. Through the snap-connection between the first groove and the first connecting block and the second groove and the second connecting block, the connection strength inside the tape body 20 is increased, so that the internal structure of the tape body 20 is more solid and reliable, not easy to delaminate or fall off, and the service life of the fiber tape is increased.

[0041] Preferably, a plurality of anti-slip blocks 11 protruding inwardly are provided in the center roll 10. By providing the anti-slip blocks 11, the surface friction of the center roll 10 is enhanced, so that the center roll 10 and the card seat are not easy to slip, and the practicality of the fiber tape is improved.
