[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0020] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model.

[0021] REFERENCE Figs. 1-3 A membrane-coated aluminum woven cloth, comprising a woven base cloth layer 1, which is woven by high-strength high-density polyethylene filaments, and the weaving nodes adopt the eight-character interlacing technology to improve the mechanical locking effect of the nodes and enhance the overall structural stability, in addition, reinforcing fibers of different material types or yarn materials of different fineness and elasticity can be added in the woven layer to optimize the physical properties of the woven layer.

[0022] The surface of the woven base cloth layer 1 and the edge of the side are connected with the shower membrane layer 2, which is coated on the surface of the woven base cloth layer 1 and the edge of the side. The uniformity of the thickness is ensured by the double-sided uniform extrusion process, so that the durability of each part of the material is the same. In particular, an additional reinforced transition zone is provided along the edge of the woven base cloth layer 1 to further improve the wear resistance of the edge. The shower membrane layer 2 is attached to the surface of the woven layer, which plays a role in waterproofing, heat insulation and protection. The high molecular polymer used in the shower membrane process can be uniformly coated or extruded to the preset thickness. After heat treatment or cold pressing, in order to ensure the consistency of the thickness of each part and maintain the uniformity of the overall durability of the material, precise flow control and automatic monitoring technology are used during application. At the same time, the mold design and production environment also need to be strictly in accordance with the standard specifications to ensure that the surface of the fabric after showering is smooth and wrinkle-free or defect-free.

[0023] The bottom of the woven base cloth layer 1 is connected with the aluminum plating layer 4 through the adhesive reinforced layer 3, which is arranged between the woven base cloth layer 1 and the aluminum plating layer 4. The adhesive is composed of acrylic modified epoxy resin with excellent wettability and curing property, and heat melting and pressing treatment is applied before the two layers are in contact to strengthen the connection between the interfaces, significantly improving the adhesion strength between the aluminum plating layer 4 and the woven layer to prevent delamination. The aluminum plating layer 4 is deposited on the bottom of the entire adhesive reinforced layer 3, and a continuous magnetron sputtering method is used to form a uniform and dense metal thin film. The aluminum plating layer 4 is a metal deposition thin film between the woven layer and the shower membrane layer, which is used to improve the reflectivity, improve the heat reflectivity and provide additional wear resistance. This layer is attached to the woven layer by chemical vapor deposition, physical vapor deposition or vacuum sputtering. Since high-strength interfacial adhesion is required, surface cleaning and roughening pretreatment is performed before aluminum plating to remove impurities and strengthen intermolecular forces. After construction is completed, corresponding test links are introduced to test whether the bonding firmness between the two meets the expected requirements to prevent problems such as delamination and peeling.

[0024] The surface of the shower membrane layer 2 is provided with micro concave-convex patterns 5, which increase the friction between the internal and external environment of the material, help to optimize the adhesion between the layers and improve the uniformity of the thickness of the shower membrane layer 2. This design significantly enhances the friction between the internal and external environment of the material without affecting the overall performance of the original material, and also increases the uniformity of the thickness of the shower membrane layer 2. The setting of the micro concave-convex patterns 5 can effectively disperse and relieve the local compressive stress caused by external force on the material, while ensuring the wear resistance and maintaining good durability. These microstructures have the effect of enhancing the interfacial interaction at the micro level, so that the functional layers can be better integrated together.

[0025] The woven base cloth layer 1 is coated with a low-friction lubricating coating layer 6, which can effectively reduce the friction between fibers, and is woven from high-strength and high-density polyethylene filaments, and the weaving nodes adopt the eight-shaped interlacing technology to ensure good mechanical strength and structural stability, thereby prolonging the service life of the woven cloth.

[0026] The woven base cloth layer 1 is formed by densely interlacing warp and weft threads, which improves the tear resistance of the woven cloth under specific loads, and the high-density weaving method enhances the basic structural strength of the cloth, so that the weaving nodes have excellent locking effect and significantly improve the tear resistance. By increasing the weaving density and optimizing the interlacing angle of the threads, the resistance of the cloth under specific loads is further improved. The tight weaving design not only improves the mechanical properties, but also provides good barrier properties. The woven wire is made of high-strength materials such as high-density polyethylene filaments, which helps to enhance the physical properties of the overall fabric. The interlaced and dense warp and weft arrangement ensures mechanical uniformity and reliability in all directions, providing a reliable basic structure for subsequent processing and use, especially when subjected to external stress, it is not easy to break or tear.

[0027] The thickness of the aluminum plating layer 4 is between 2 μm and 5 μm, which can maintain good electromagnetic shielding effect while minimizing the weight and hardness change of the material. This feature is achieved by precisely adjusting the key parameters during the aluminum plating process. Reasonable thickness setting not only maintains excellent electromagnetic shielding performance to a large extent, but also effectively reduces the overall weight of the product and slows down the increase in hardness caused by the addition of a metal coating, thereby not affecting the flexibility and easy processing characteristics of the material in different application scenarios. The adhesive reinforcement layer 3 is composed of acrylic modified epoxy resin.

[0028] The specific working principle of the utility model is as follows:

[0029] In actual operation process, when this device uses, first by high-strength high-density polyethylene filaments woven woven base cloth layer 1 as the main structure, on this basis, utilize eight-shaped interlacing technology to process the weaving node, to ensure that each node has higher mechanical locking effect and enhances the stability of the overall structure, then, the film layer 2 is coated on the upper surface and the side edge of the woven base cloth layer 1 by double-sided uniform extrusion process, and an additional reinforced transition zone is provided at the edge part, so as to improve the overall durability and wear resistance of the material.

[0030] Next, a bonding agent reinforcing layer 3 composed of an acrylic modified epoxy resin is added between the woven base layer 1 and the aluminum plating layer 4, and a hot melt pressing process is performed on the layer to ensure more firm interface connection, effectively preventing delamination between the aluminum plating layer 4 and the woven layer, finally, a uniform and dense aluminum plating layer 4 is deposited on the bottom of the entire bonding agent reinforcing layer 3 using a continuous magnetron sputtering method, thereby realizing overall protection and function enhancement of the final product.

[0031] The above merely describes a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, should be covered within the protection scope of the present application.
