Description

Technical Field

[0001] This utility model relates to the field of high-temperature resistant webbing technology, specifically to a high-temperature resistant webbing structure with a flame-retardant and heat-insulating layer. Background Technology

[0002] High-temperature resistant webbing refers to webbing that can withstand high temperatures (e.g., 200℃) and be used normally. High-temperature resistant webbing is usually woven from high-temperature resistant fibers. Its characteristics include high melting point and softening point, dimensional stability at high temperatures, and large molecular structure that is not easily degraded (long-term use temperature can reach above 200℃). It also has good resistance to hydrolysis and chemical agents.

[0003] Chinese patent CN213086226U discloses a high-temperature resistant webbing, including a main body and through holes. The upper end of the main body is provided with an upper binding edge, and the lower end of the main body is provided with a lower binding edge. The through holes are located inside the reinforcing strips. This high-temperature resistant webbing features two sets of reinforcing strips, symmetrically distributed about the vertical center line of the main body. When the main body is subjected to strong tensile force, the design of the reinforcing strips effectively improves the overall strength of the main body, preventing breakage. Simultaneously, this design avoids deformation of the main body to a certain extent. The reinforcing strips prevent direct contact between sharp objects and the outer wall of the main body, providing a certain degree of protection. The warp yarns are evenly distributed inside the main body, and the warp and weft yarns form a cross-shaped structure. This cross-shaped distribution further improves the strength of the main body. The interlocking and interweaving of the warp and weft yarns increases the friction between them, resulting in low tensile deformation and a long service life.

[0004] However, the aforementioned high-temperature resistant webbing lacks tensile strength during use. Under high temperatures, its winding rope is prone to softening, breaking, and loosening, and its high-temperature applicability is poor. Utility Model Content

[0005] The present invention aims to solve the problems mentioned in the background art by providing a high-temperature resistant webbing structure with a flame-retardant and heat-insulating layer.

[0006] The specific technical solution is as follows:

[0007] A high-temperature resistant webbing structure with a flame-retardant and heat-insulating layer includes a webbing body and a flame-retardant component. Aerogel felt is connected to both sides of the webbing body. The flame-retardant component is connected to one side of the aerogel felt. The webbing body is wrapped with the aerogel felt by the flame-retardant component to form a flame-retardant and heat-insulating layer. The surface of the webbing body is provided with wavy vertical stripes and wavy horizontal stripes, which are distributed in a crisscross pattern.

[0008] As a preferred embodiment of this utility model, the aerogel felt is made of silicon dioxide material and serves as a heat insulation layer, and a stainless steel mesh is embedded inside the aerogel felt.

[0009] As a preferred embodiment of the present invention, the flame-retardant component includes a flame-retardant layer, which is woven from basalt fibers and is fixedly connected to one side of the aerogel felt by a high-temperature resistant adhesive.

[0010] As a preferred embodiment of this utility model, the flame-retardant layer surface is provided with multiple sets of anti-bending strips equidistantly distributed along the length direction, and the anti-bending strips are in the shape of a wave-shaped structure.

[0011] As a preferred embodiment of this utility model, both ends of the flame-retardant layer are connected with connecting strips, and the connecting strips have through holes, in which metal rings are installed.

[0012] As a preferred embodiment of this utility model, the flame-retardant layer is coated with an intumescent flame-retardant coating.

[0013] This utility model has the following beneficial effects:

[0014] 1. The high-temperature resistant webbing structure with flame-retardant and heat-insulating layer provided by this utility model, through the design of aerogel felt, flame-retardant components, and wavy horizontal and vertical patterns, can improve the tensile strength of the webbing body through the crisscrossing wavy patterns. Then, the aerogel felt is made of silica material, which hinders heat conduction and effectively slows down the conduction speed of external heat to the webbing body, thereby playing a heat insulation role. Furthermore, the stainless steel mesh embedded in the aerogel felt enhances the structural strength of the aerogel felt, prevents it from being easily damaged during use, and ensures the stable performance of the heat insulation function. Finally, the flame-retardant components can prevent heat from being transferred to the webbing body, thereby achieving heat insulation and flame retardancy of the webbing body and improving the safety of use.

[0015] 2. The high-temperature resistant webbing structure with a flame-retardant and heat-insulating layer provided by this utility model, through the design of the flame-retardant layer, anti-bending strips, and metal rings, features a flame-retardant layer woven from basalt fiber, which has excellent flame-retardant properties and can remain stable in high-temperature environments. The anti-bending strips on the surface of the flame-retardant layer are wavy, which can absorb bending energy through corrugated deformation, effectively preventing the flame-retardant layer from cracking due to repeated bending and enhancing structural stability. Then, the connecting strips at both ends of the flame-retardant layer, with metal rings inside the connecting strips, can easily connect the webbing to other components. The intumescent flame-retardant coating on the surface of the flame-retardant layer isolates oxygen and inhibits combustion, thereby meeting the needs of webbing connection in different scenarios and improving the high-temperature applicability of the webbing itself.

[0029] Example 1

[0030] The high-temperature resistant webbing structure with a flame-retardant and heat-insulating layer provided in this embodiment is as follows: Figures 1-5 As shown, the device includes a webbing body 1 and a flame-retardant component 2. Aerogel felt 3 is connected to both sides of the webbing body 1. The flame-retardant component 2 is connected to one side of the aerogel felt 3. The webbing body 1 is wrapped with the aerogel felt 3 by the flame-retardant component 2 to form a flame-retardant and heat-insulating layer. The surface of the webbing body 1 has wavy vertical stripes 103 and wavy horizontal stripes 104, which are distributed in a crisscross pattern. The aerogel felt 3 is made of silica material and serves as the heat-insulating layer. A stainless steel mesh 301 is embedded inside the aerogel felt 3.

[0031] Through the design of aerogel felt 3, flame retardant component 2, wavy horizontal stripe 104, and wavy vertical stripe 103, the crisscrossing wavy patterns can improve the tensile strength of the webbing body 1. Then, the aerogel felt 3 is made of silica material, which hinders heat conduction and effectively slows down the conduction speed of external heat to the webbing body 1, thereby playing a heat insulation role. Furthermore, the stainless steel mesh 301 is embedded in the aerogel felt 3 to enhance the structural strength of the aerogel felt 3, prevent it from being easily damaged during use, and ensure the stable performance of the heat insulation function. Then, the flame retardant component 2 can prevent heat from being transferred to the webbing body 1, thereby achieving the heat insulation and flame retardant effect of the webbing body 1 and improving the safety of use.

[0032] Example 2

[0033] The high-temperature resistant webbing structure with a flame-retardant and heat-insulating layer provided in this embodiment is as follows: Figures 3-5 As shown, the flame-retardant component 2 includes a flame-retardant layer 201, which is woven from basalt fibers and fixedly connected to one side of the aerogel felt 3 using a high-temperature resistant adhesive. The surface of the flame-retardant layer 201 has multiple sets of equidistant bending strips 202 distributed along its length, and the bending strips 202 have a wavy shape. Connecting straps 101 are connected to both ends of the flame-retardant layer 201, and the connecting straps 101 have through holes in which metal rings 102 are installed. The surface of the flame-retardant layer 201 is coated with an intumescent flame-retardant coating.

[0034] Through the design of flame-retardant layer 201, anti-bending strip 202, and metal ring 102, flame-retardant layer 201 is woven from basalt fiber, which has good flame-retardant performance and can remain stable in high-temperature environments. The anti-bending strip 202 on the surface of flame-retardant layer 201 is wavy, which can absorb bending energy through corrugation deformation, effectively preventing the flame-retardant layer 201 from cracking due to repeated bending and enhancing structural stability. Then, the connecting strip 101 connected to both ends of flame-retardant layer 201 and the metal ring 102 in the connecting strip 101 can easily connect the webbing to other components. The intumescent flame-retardant coating on the surface of flame-retardant layer 201 isolates oxygen and inhibits combustion, thereby meeting the needs of webbing connection in different scenarios and improving the high-temperature applicability of webbing body 1.

[0035] In summary, the high-temperature resistant webbing structure with flame-retardant and heat-insulating layer provided in this embodiment has the following advantages: through the design of the horizontal wave pattern 104 and the vertical wave pattern 103, the crisscrossing wave pattern can improve the tensile strength of the webbing body 1, extend the service life of the webbing body 1, reduce replacement costs, and improve the high-temperature applicability of the webbing body 1 through the flame-retardant layer 201 heat-insulating layer.

[0036] In use, the aerogel felt 3, made of silica, hinders heat conduction and effectively slows down the transfer of external heat to the webbing body 1, thus providing heat insulation. The stainless steel mesh 301 is embedded in the aerogel felt 3 to enhance its structural strength. Then, the flame-retardant layer 201, woven from basalt fiber, has good flame-retardant properties and can remain stable in high-temperature environments. The wavy anti-bending strips 202 on the surface of the flame-retardant layer 201 can absorb bending energy through corrugated deformation, effectively preventing the flame-retardant layer 201 from cracking due to repeated bending. The crisscrossing wavy patterns on the surface of the webbing body 1 can improve the tensile strength of the webbing body 1.
