Description

Technical Field

[0001] This utility model relates to the field of fire-resistant and high-temperature resistant tape technology, and in particular to a fire-resistant and high-temperature resistant tape. Background Technology

[0002] Fire-retardant and high-temperature resistant tape is a type of tape specifically designed for high-temperature and fire-hazardous environments. It possesses excellent high-temperature resistance, flame retardancy, and insulation properties. It is commonly used in industries such as electrical equipment, aerospace, construction, and automotive manufacturing to ensure good adhesion and protective effects even in high-temperature or fire environments. Fire-retardant and high-temperature resistant tape is typically made of high-temperature resistant materials such as polyimide (Kapton), glass fiber, and ceramic fiber, coated with a special high-temperature resistant adhesive, such as silicone or fluorosilicone rubber. The temperature range this tape can withstand is typically between 200°C and 1000°C, depending on the materials used. Certain types of tape can even withstand higher temperatures for short periods. Fire-retardant tape has excellent flame retardancy, not only withstanding high temperatures but also maintaining structural stability in flames, preventing the spread of fire. Therefore, it is often used in environments requiring fire protection.

[0003] However, existing fire-resistant and high-temperature resistant tapes are insufficient in their ability to block and reflect heat radiation, leaving room for improvement in their flame-retardant and temperature-resistant properties. Utility Model Content

[0004] Therefore, it is necessary to provide a fire-resistant and high-temperature resistant tape to address the technical problem that existing fire-resistant and high-temperature resistant tapes are insufficient in blocking and reflecting heat radiation.

[0005] A fire-resistant and high-temperature resistant tape includes a substrate layer, an adhesive layer, a reinforcing layer, a heat insulation layer, and a flame-retardant layer. The adhesive layer is disposed on one side surface of the substrate layer, the reinforcing layer is disposed on the other side surface of the substrate layer, the heat insulation layer is disposed on the side surface of the reinforcing layer opposite to the substrate layer, and the flame-retardant layer is disposed on the side surface of the heat insulation layer opposite to the reinforcing layer, thereby forming a complete tape.

[0006] The substrate layer includes a fiberglass cloth layer and an aluminum foil layer, which are stacked sequentially. The fiberglass cloth layer is disposed on the adhesive layer side and the aluminum foil layer is disposed on the reinforcing layer side, thus the substrate layer adopts a composite layer structure.

[0007] In one embodiment, the adhesive layer described above is uniformly coated on the surface of the substrate layer using an organosilicon adhesive.

[0008] In one embodiment, the aforementioned reinforcing layer is made of polyester fiber mesh material laid on the other side surface of the substrate layer.

[0009] In one embodiment, the aforementioned heat insulation layer is made of aerogel material laid on the surface of the reinforcing layer to form a porous structure.

[0010] In one embodiment, the flame-retardant layer is configured as a flame-retardant coating uniformly applied to the surface of the heat insulation layer.

[0011] In one embodiment, the thickness of the aluminum foil layer is set to 30-50 μm.

[0012] In one embodiment, the surface of the aluminum foil layer facing the reinforcing layer is set to a high-gloss surface.

[0013] In one embodiment, the aluminum foil layer is provided with a plurality of hemispherical grooves of a predetermined diameter on the side surface facing the reinforcing layer. The plurality of hemispherical grooves are closely arranged on the surface of the aluminum foil layer, thereby forming a dense surface embossed structure on the surface of the aluminum foil layer.

[0014] In one embodiment, the surface of the aluminum foil layer is provided with a heat-insulating coating, which is applied to the surface of the aluminum foil layer.

[0015] In one embodiment, the aforementioned heat-insulating coating may be one of an organosilicon coating, a polytetrafluoroethylene coating, and a metal oxide nano-coating.

[0016] In one embodiment, the aforementioned heat-insulating coating is configured as a metal oxide nanocoating, and the heat-insulating coating is applied to the side surface of the aluminum foil layer facing the reinforcing layer.

[0017] The aforementioned fire-resistant and high-temperature resistant tape forms a heat insulation barrier through a heat insulation layer, thereby enhancing the heat insulation layer's ability to prevent heat conduction. A flame-retardant layer is uniformly coated on the surface of the heat insulation layer, thereby improving the overall fire resistance of the tape surface and preventing direct contact between open flames and the substrate, thus preventing the substrate from burning. Furthermore, the substrate layer includes a fiberglass cloth layer and an aluminum foil layer, which are stacked sequentially. The fiberglass cloth layer is located on the adhesive layer side, and the aluminum foil layer is located on the reinforcing layer side. Thus, the substrate layer adopts a composite layer structure, further enhancing the tape's fire resistance and high-temperature resistance. The fiberglass cloth layer is made of fiberglass cloth, which has extremely high heat and fire resistance, capable of withstanding temperatures above 600℃. The aluminum foil layer uses aluminum foil of a predetermined thickness as a reflective layer structure of the substrate to reflect heat, effectively reducing temperature conduction and preventing the spread of fire.

[0026] Please see Figures 1 to 2This utility model discloses a fire-resistant and high-temperature resistant tape, which includes a substrate layer 100, an adhesive layer 200, a reinforcing layer 300, a heat insulation layer 400, and a flame-retardant layer 500. The adhesive layer 200 is disposed on one side surface of the substrate layer 100, the reinforcing layer 300 is disposed on the other side surface of the substrate layer 100, the heat insulation layer 400 is disposed on the side surface of the reinforcing layer 300 opposite to the substrate layer 100, and the flame-retardant layer 500 is disposed on the side surface of the heat insulation layer 400 opposite to the reinforcing layer 300, thereby forming a complete tape. In one embodiment, the adhesive layer 200 is made of silicone adhesive uniformly coated on the surface of the substrate layer 100. The silicone adhesive has high temperature resistance. It exhibits good stability and excellent adhesion to various substrates, making it suitable for long-term use in high-temperature environments. The reinforcing layer 300 is made of polyester fiber mesh material laid on the other side of the substrate layer 100 to increase the overall tensile strength of the tape and prevent cracking during use in high-temperature environments. The heat insulation layer 400 is made of aerogel material laid on the surface of the reinforcing layer 300 to form a porous structure. The air inside the pores can form a heat insulation barrier, thereby improving the heat insulation layer 400's ability to prevent heat conduction. The flame retardant layer 500 is a flame retardant coating uniformly applied to the surface of the heat insulation layer 400 to improve the overall fire resistance of the tape surface and prevent direct contact of open flames with the substrate from causing the substrate to burn. Specifically, the substrate layer 100 includes a fiberglass cloth layer 110 and an aluminum foil layer 120, which are stacked sequentially. The fiberglass cloth layer 110 is disposed on one side of the adhesive layer 200, and the aluminum foil layer 120 is disposed on one side of the reinforcing layer 300. Thus, the substrate layer 100 adopts a composite layer structure, which further enhances the fire resistance and high temperature resistance of the tape. The fiberglass cloth layer 110 is made of fiberglass cloth, which has extremely high heat resistance and fire resistance and can withstand temperatures above 600°C. The aluminum foil layer 120 uses aluminum foil of a predetermined thickness as a reflective layer structure to reflect heat, effectively reducing temperature conduction and preventing the spread of fire.

[0027] Furthermore, the thickness of the aluminum foil layer 120 is set to 30-50μm, thereby improving the temperature resistance and reflectivity of the aluminum foil layer 120 while ensuring its flexibility, thus achieving a balance between the thermal reflectivity and mechanical properties of the aluminum foil layer 120.

[0028] Furthermore, the surface of the aluminum foil layer 120 facing the reinforcing layer 300 is configured with a high-gloss finish. The smoothness of the aluminum foil surface directly affects its reflective properties. The high-gloss finish treatment can improve the reflectivity of the aluminum foil layer 120 for most radiant heat, effectively reducing heat entering the glass fiber sublayer. In practical production applications, the surface of the aluminum foil layer 120 can be treated by polishing or electroplating to further improve its reflectivity and enhance its ability to reflect infrared radiation.

[0029] Furthermore, the aluminum foil layer 120 has a plurality of hemispherical grooves a of a predetermined diameter on the surface facing the reinforcing layer 300. These hemispherical grooves a are closely arranged on the surface of the aluminum foil layer 120, thereby forming a dense surface embossing structure. In this embodiment, the dense hemispherical grooves a embossing structure of the aluminum foil layer 120 adjusts the reflection angle of incident light irradiating its surface, causing heat radiation to be reflected multiple times in different directions. This enhances the overall reflectivity of the aluminum foil layer 120, increasing both its heat reflection performance and structural strength.

[0030] Furthermore, a heat-insulating coating 121 is provided on the surface of the aluminum foil layer 120. The heat-insulating coating 121 is applied to the surface of the aluminum foil layer 120 to improve the heat insulation and heat resistance performance of the aluminum foil layer 120. Specifically, the heat-insulating coating 121 can be one of an organosilicon coating, a polytetrafluoroethylene coating, and a metal oxide nano-coating, thereby enabling the heat-insulating coating 121 to further enhance the heat resistance and heat insulation performance of the filter layer while maintaining flexibility.

[0031] In one embodiment, the heat-insulating coating 121 is a metal oxide nano-coating, and the heat-insulating coating 121 is coated on the side surface of the aluminum foil layer 120 facing the reinforcing layer 300. The metal oxide nano-coating, such as the titanium dioxide coating, can provide higher flexibility while maintaining high reflectivity and heat insulation, thereby further improving the reflectivity of the aluminum foil layer 120 to heat radiation, and thus improving the overall fire resistance and high temperature resistance of the tape.

[0032] In summary, the fire-resistant and high-temperature resistant tape disclosed in this utility model forms a heat insulation barrier through a heat insulation layer, thereby enhancing the heat insulation layer's ability to prevent heat conduction. A flame-retardant layer is uniformly coated on the surface of the heat insulation layer, thereby improving the overall fire resistance of the tape surface and preventing direct contact between open flames and the substrate, thus preventing the substrate from burning. Furthermore, the substrate layer includes a fiberglass cloth layer and an aluminum foil layer, which are stacked sequentially. The fiberglass cloth layer is disposed on the adhesive layer side, and the aluminum foil layer is disposed on the reinforcing layer side. Thus, the substrate layer adopts a composite layer structure, which further enhances the fire resistance and high-temperature resistance of the tape. The fiberglass cloth layer is made of fiberglass cloth, which has extremely high heat resistance and fire resistance, capable of withstanding temperatures above 600℃. The aluminum foil layer uses aluminum foil of a predetermined thickness as a reflective layer structure of the substrate to reflect heat, effectively reducing temperature conduction and preventing the spread of fire.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
