[0002] Adhesive tape, as an important bonding material in modern industry, typically consists of a substrate layer (including polymer film, non-woven fabric, and specialty paper) and an adhesive coating. These composite materials, with their convenient application and reliable bonding performance, have achieved large-scale use in numerous fields such as packaging, electronic component fixing, automotive wiring harness bundling, building waterproofing and sealing, and industrial equipment protection. However, due to its relatively low high-temperature resistance, adhesive tape cannot meet the needs of users in high-temperature environments. Utility Model Content

[0003] The purpose of this invention is to provide a high-temperature resistant tape, which solves the problem that the tape's low high-temperature resistance prevents it from meeting the user's needs in high-temperature environments.

[0010] The present invention is further configured such that the composite flame retardant layer includes a montmorillonite layer and an aluminum hydroxide layer, wherein the bottom of the montmorillonite layer is bonded to the upper surface of the ceramic microsphere layer, and the upper surface of the montmorillonite layer is bonded to the bottom of the aluminum hydroxide layer.

[0011] The technical effects achieved by this utility model are as follows:

[0012] This invention relates to a high-temperature resistant tape, which combines a graphite layer, a polyimide layer, an aramid fiber layer, and a polyetheretherketone layer to achieve strong high-temperature resistance. Furthermore, the combination of a microporous silicone rubber layer, an elastic compensation layer, and a reinforcing mesh layer prevents the tape from easily deforming when heated.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1 to 2 As shown, a high-temperature resistant tape includes a substrate layer 1, an anti-deformation layer 2 bonded to the upper surface of the substrate layer 1, an aerogel layer 3 bonded to the upper surface of the anti-deformation layer 2, a graphite layer 4 bonded to the upper surface of the aerogel layer 3, a polyimide layer 5 bonded to the upper surface of the graphite layer 4, an aramid fiber layer 6 bonded to the upper surface of the polyimide layer 5, a polyetheretherketone layer 7 bonded to the upper surface of the aramid fiber layer 6, a pressure-sensitive adhesive layer 8 bonded to the bottom of the substrate layer 1, and a silicone release paper layer 9 bonded to the bottom of the pressure-sensitive adhesive layer 8.

[0022] The anti-deformation layer 2 includes a microporous silicone rubber layer 201, an elastic compensation layer 202, and a reinforcing mesh layer 203. The upper surface of the microporous silicone rubber layer 201 is bonded to the bottom of the aerogel layer 3, the bottom of the microporous silicone rubber layer 201 is bonded to the upper surface of the elastic compensation layer 202, the bottom of the elastic compensation layer 202 is bonded to the upper surface of the reinforcing mesh layer 203, and the bottom of the reinforcing mesh layer 203 is bonded to the upper surface of the substrate layer 1.

[0023] It should be noted that the microporous silicone rubber layer 201 absorbs thermal expansion stress, the elastic compensation layer 202 is a thermoplastic elastomer, the elastic compensation layer 202 compensates for dimensional changes at high temperatures, and the reinforcing mesh layer 203 is a fiberglass woven mesh, which inhibits lateral shrinkage. Through the combination of the microporous silicone rubber layer 201, the elastic compensation layer 202 and the reinforcing mesh layer 203, the tape is not easily deformed after being heated.

[0024] The aerogel layer 3 reduces the impact of heat conduction on the substrate layer 1. The combination of graphite layer 4, polyimide layer 5, aramid fiber layer 6 and polyetheretherketone layer 7 gives the tape strong high-temperature resistance. The pressure-sensitive adhesive layer 8 allows the tape to adhere to the object. The silicone release paper layer 9 protects the pressure-sensitive adhesive layer 8 and can be directly peeled off from the pressure-sensitive adhesive layer 8.

[0025] like Figures 1 to 3 As shown, a metallized polyester film layer 10 is bonded to the upper surface of the polyetheretherketone layer 7, an aluminum foil layer 11 is bonded to the upper surface of the metallized polyester film layer 10, a ceramic microsphere layer 12 is bonded to the upper surface of the aluminum foil layer 11, and a composite flame retardant layer 13 is bonded to the upper surface of the ceramic microsphere layer 12.

[0026] The composite flame retardant layer 13 includes a montmorillonite layer 1301 and an aluminum hydroxide layer 1302. The bottom of the montmorillonite layer 1301 is bonded to the upper surface of the ceramic microsphere layer 12, and the upper surface of the montmorillonite layer 1301 is bonded to the bottom of the aluminum hydroxide layer 1302.

[0027] It should be noted that the metallized polyester film layer 10, aluminum foil layer 11 and ceramic microsphere layer 12 can reflect external heat and reduce the absorption of external heat by the tape, thereby further improving the high temperature resistance of the tape. The combination of montmorillonite layer 1301 and aluminum hydroxide layer 1302 gives the tape a certain flame retardant ability.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
