[0035] To further understand the utility model content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:
[0036] Example 1:
[0037] like Figures 1-3 As shown, the high-temperature resistant hook and loop fastener assembly includes a first hook and loop fastener 1 and a second hook and loop fastener 2, which are matched and connected for use. Both the first hook and loop fastener 1 and the second hook and loop fastener 2 are provided with a load-bearing layer 3, a high-temperature resistant layer 4, and an adhesive layer 5. The high-temperature resistant layer 4 and the load-bearing layer 3 are fixedly connected, and the adhesive layer 5 and the high-temperature resistant layer 4 are also fixedly connected. The high-temperature resistant layer 4 includes a ceramic fiber layer 41 and a flame-retardant coating 42. Both the ceramic fiber layer 41 and the flame-retardant coating 42 are provided in at least two layers. The ceramic fiber layer 41 is a ceramic fiber cloth woven from cross-woven ceramic fiber filaments. The ceramic fiber layer 41 and the flame-retardant coating 42 are alternately layered and joined by hot-pressing. In this embodiment, the ceramic fiber layer has a low thermal conductivity, forming a physical heat insulation barrier. The flame-retardant coating can block heat transfer. The alternating layering of the fiber layer and the flame-retardant coating can achieve a synergistic effect of both physical heat insulation and chemical flame retardancy, avoiding the risk of single-layer structure failure due to high temperature. Moreover, the alternating layering method can enhance the connection strength of the high-temperature resistant layer, making it less prone to delamination. Of course, the above is not limited to this; it can be any other method that avoids the risk of single-layer structure failure due to high temperature and is not easy to delaminate.
[0038] Specifically, the ceramic fiber layer 41 is a ceramic fiber cloth. In this embodiment, the ceramic fiber cloth has good high-temperature resistance and low thermal conductivity, which can form a physical flame-retardant barrier for the hook and loop fastener assembly. Of course, it is not limited to this; other materials can be used to form a physical flame-retardant barrier for the hook and loop fastener assembly.
[0039] Specifically, a flame-retardant coating 42 is applied to the outside of the adhesive layer 5. In this embodiment, this design effectively prevents the adhesive layer from igniting due to high temperatures generated by repeated friction, eliminating the overall failure of traditional hook and loop fasteners caused by localized weak points. Of course, it is not limited to this; other methods to prevent the adhesive layer from igniting due to repeated friction can also be used.
[0040] Specifically, the load-bearing layer 3 includes a flame-retardant silicone layer 31 and a glass fiber layer 32, which are fixedly connected to the high-temperature resistant layer 4. In this embodiment, the flame-retardant silicone layer provides a flexible sealing layer to prevent the penetration of external fire sources; the glass fiber layer enhances the tear resistance of the composite layer, preventing the silicone layer from being damaged by mechanical forces. Of course, it is not limited to this; other methods can be used to prevent the penetration of external fire sources and enhance the tear resistance of the composite layer.
[0041] Specifically, a high-temperature resistant adhesive layer 6 is provided between the load-bearing layer 3 and the high-temperature resistant layer 4. The adhesive layer 6 is made of silicone-modified epoxy resin. In this embodiment, the adhesive layer fills the pores of the load-bearing layer and forms chemical bonds with the high-temperature resistant layer, reducing interface defects. Of course, it is not limited to this and can also be other high-temperature resistant adhesives.
[0042] Specifically, the adhesive layers 5 of the first hook and loop fastener 1 and / or the second hook and loop fastener 2 are the same or mutually matched. In this embodiment, the first hook and loop fastener and the second hook and loop fastener are connected by matching adhesive layers to ensure a stable connection and prevent them from easily falling off. Of course, this is not limited to this; other methods can be used to ensure a stable connection between the first hook and loop fastener and the second hook and loop fastener.
[0043] Specifically, such as Figure 2 As shown, the adhesive layer 5 of the first hook and loop fastener 1 and / or the second hook and loop fastener 2 includes a connecting carrier 51 and a connecting portion 52. The connecting carrier 51 and the connecting portion 52 are fixedly connected or integrally formed. The connecting carrier 51 and the high-temperature resistant layer 4 are fixedly connected. The shape of the connecting portion 52 is a hook shape, a ball shape, a cross shape, or a triangle shape. In this embodiment, both the first hook and loop fastener and the second hook and loop fastener have a connecting carrier and a connecting portion. The first hook and loop fastener and the second hook and loop fastener can be connected by snapping together through the connecting portion. The design of the shape of the connecting portion can make the connection between the hook and loop fasteners stable and not easy to fall off. Of course, it is not limited to this; other methods can be used to achieve a stable connection between the first hook and loop fastener and the second hook and loop fastener.
[0044] Working principle: when in use, the first and second hook-and-loop fasteners are connected through the connecting part to realize the connection of the two; the high-temperature-resistant layer includes a fiber layer and a flame-retardant coating, and both the fiber layer and the flame-retardant coating are provided with at least two layers, and the fiber layer and the flame-retardant coating are alternately stacked. The fiber layer has a low thermal conductivity, forming a physical heat shield, and the flame-retardant coating can block heat transfer, and the alternately stacked mode can realize the synergistic effect of the double mechanisms of physical heat insulation and chemical flame retardation, avoiding the risk of failure of a single-layer structure due to high temperature, and the alternately stacked mode can enhance the connection firmness of the high-temperature-resistant layer, so that it is not easy to delaminate. The flame-retardant coating is coated on the adhesive layer. This setting effectively prevents the adhesive layer from burning due to high temperature caused by repeated friction, eliminating the overall failure of traditional hook-and-loop fasteners due to local weak points. The load-bearing layer includes a flame-retardant silicone layer and a glass fiber layer, and the flame-retardant silicone layer and the glass fiber layer are fixedly connected with the high-temperature-resistant layer. The flame-retardant silicone layer provides a flexible sealing layer to block the penetration of external fire sources; the glass fiber layer enhances the tear resistance of the composite layer to prevent the silicone layer from being damaged by mechanical external force. A high-temperature-resistant adhesive layer is arranged between the load-bearing layer and the high-temperature-resistant layer, and the material of the adhesive layer is organic silicon modified epoxy resin. The adhesive layer fills the pores of the load-bearing layer and forms a chemical bond with the high-temperature-resistant layer, reducing interface defects.
[0045] Example two:
[0046] Example one and example two have basically the same structure, the main difference is:
[0047] Specifically, as shown in Figure 3 , the adhesive layer 5 of the first hook-and-loop fastener 1 or the second hook-and-loop fastener 2 is a plush surface or the adhesive layer 5 and the high-temperature-resistant layer 4 are connected to form a closed loop. In this embodiment, one of the hook-and-loop fasteners includes a connecting carrier and a connecting part, and the connecting part has a hook body shape, a ball head shape, a cross shape or a triangular shape; the adhesive layer of the other hook-and-loop fastener is a plush surface or the adhesive layer and the high-temperature-resistant layer are connected to form a closed loop; the connecting part is hooked into the closed loop formed by the adhesive layer and the high-temperature-resistant layer to realize stable connection between the first hook-and-loop fastener and the second hook-and-loop fastener.
[0048] The technical features of the above-described embodiments can be combined in any way. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.
[0049] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
