Although it can meet the basic edge sealing requirements, it is prone to problems such as aging and falling off of the edge sealing materials during long-term use. Especially in high humidity and high temperature environments, these problems are more prominent. In addition, the traditional edge sealing structure also has certain shortcomings in aesthetics, durability and sound insulation, and cannot meet consumers' pursuit of high-quality life. Therefore, it is necessary to improve the existing technical solutions and provide a more stable, beautiful and durable composite door edge sealing structure. Utility Model Content

[0005] When in use, the edge banding strip and the door body are installed with adhesive. The frosted layer can increase the contact area of ​​the adhesive, making the edge banding strip and the door body bonded more tightly. The glass fiber layer is non-flammable, has strong corrosion resistance, high mechanical strength, and good heat insulation and sound insulation. It can effectively enhance the impact resistance and deformation resistance of the edge banding structure. The glass wool sound insulation layer is a soft, porous material with good sound insulation and fire prevention properties, which can play a role in heat preservation, sound insulation and fire prevention.

[0008] Preferably, a moisture-proof layer is provided on one side of the glass fiber layer, and a fire-proof layer is provided on the other side of the glass fiber layer.

[0009] The moisture-proof layer has good moisture-proof performance and can prevent moisture from corroding the door body. The fire-proof layer has good fire-proof performance and improves the durability of the structure.

[0010] Preferably, the protective layer consists of a decorative layer and a wear-resistant layer, and the decorative layer is arranged outside the wear-resistant layer.

[0011] The decorative layer adopts environmentally friendly and weather-resistant finishing materials, such as PVC film or solid wood veneer, which not only improves the aesthetics of the edge banding structure, but also can resist the erosion of the edge banding structure by the external environment to a certain extent. The wear-resistant layer adopts transparent paint with good wear resistance to protect the inner layer material.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The utility model can effectively enhance the impact resistance and deformation resistance of the edge sealing structure through the advantages of non-flammability, corrosion resistance, high mechanical strength, and good heat insulation and sound insulation of the glass fiber layer. The glass wool sound insulation layer is a soft, porous material with good sound insulation and fire prevention properties, which can play a role in heat preservation, sound insulation and fire prevention. Moreover, due to the wave design, it can absorb noise more fully, and has a better sound insulation effect when the door is closed, thereby enhancing the user experience.

[0018] The following specific embodiments are provided to help the reader obtain a comprehensive understanding of the methods, devices and / or systems described herein. However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example, and is not limited to the order set forth herein, but in addition to the operations that must occur in a particular order, changes that will be apparent after understanding the disclosure of the present application may be made. In addition, in order to improve clarity and brevity, descriptions of features known in the art may be omitted.

[0019] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0020] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0021] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0022] Although terms such as "first", "second", and "third" may be used herein to describe various components, assemblies, regions, layers, or portions, these components, assemblies, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one component, component, region, layer, or portion from another component, component, region, layer, or portion. Therefore, without departing from the teachings of the examples described herein, the first component, component, region, layer, or portion referred to may also be referred to as the second component, component, region, layer, or portion.

[0023] For ease of description, spatial relative terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another element as shown in the drawings. Such spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, an element described as being "above" or "upper" relative to another element would then be located "below" or "lower" relative to the other element.

[0024] Therefore, the term "above" includes both "above" and "below" orientations depending on the spatial orientation of the device. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative terms used herein will be interpreted accordingly.

[0025] The terms used herein are only used to describe various examples and are not used to limit the present disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms "include", "comprise" and "have" list the stated features, quantities, operations, components, elements and / or their combinations that exist, but do not exclude the existence or addition of one or more other features, quantities, operations, components, elements and / or their combinations.

[0026] Variations in the shapes shown in the drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include variations in shapes that occur during manufacturing.

[0027] The features of the examples described herein may be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, it will be apparent after understanding the disclosure of the present application that other configurations are possible.
