[0017] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the utility model.

[0018] The utility model provides a composite xuan paper card as Figure 1-2 shown, which includes a surface layer 1. A back layer 2 is arranged below the surface layer 1. An intermediate layer 3 is arranged between the surface layer 1 and the back layer 2. The surface layer 1, the intermediate layer 3, and the back layer 2 are connected through a connecting layer 4. Both the surface layer 1 and the back layer 2 are kapok pulp paper.

[0019] Furthermore, the intermediate layer 3 is composed of a combination of a high-strength layer 31, an antibacterial layer 32, a heat-insulating layer 33, an ink-absorbing layer 34, an anti-static layer 35, and a flame-retardant layer 36. The high-strength layer 31, the antibacterial layer 32, the heat-insulating layer 33, the ink-absorbing layer 34, the anti-static layer 35, and the flame-retardant layer 36 are all connected through the connecting layer 4.

[0020] Specifically, the high-strength layer 31 is one of polyethylene, polypropylene, polyester film, and aluminized film. Polymer films such as polyethylene, polypropylene, or polyester can be added to the middle of the art paper through methods such as coating, laminating, or lamination. These polymer films have excellent strength and durability, and can provide additional tear resistance, tensile resistance, and wear resistance. Adding a metallized layer, such as aluminized film, to the middle of the art paper can increase the strength and shielding properties of the paper. The metallized layer can provide good moisture resistance, sun protection, and antioxidant properties, while enhancing the durability of the paper. Adding the high-strength layer 31 can make the art paper tougher and more durable, suitable for applications such as packaging, labels, and cards that require high strength and durability. Moreover, for items that require extra protection, such as precious documents, photos, or artworks, a high-strength layer can be added to the middle of the art paper to provide an additional protective barrier against damage or scratches. It can also increase the stability of the art paper and reduce deformation and curling of the paper under the influence of humidity changes or other environmental factors, which is very important for maintaining a flat and precise drawing, printing, or writing surface.

[0021] Specifically, the antibacterial layer 32 is one of silver ion antibacterial agents, zinc oxide, and copper ion antibacterial agents. Silver ions have broad-spectrum antibacterial activity and can effectively inhibit the growth of bacteria, fungi, and viruses. Adding silver ions to the middle of the art paper can achieve antibacterial effects by slowly releasing silver ions. Zinc oxide is a natural antibacterial agent with broad-spectrum antibacterial activity. It can be added to the paper through physical or chemical methods to provide antibacterial protection. Copper ions also have antibacterial properties and can exist stably for a long time. Loading copper ions onto the paper can achieve antibacterial functions. Adding the antibacterial layer 32 can endow the art paper with certain antibacterial ability, reduce the spread and growth of bacteria, and is particularly suitable for fields related to food, medicine, and hygiene, such as packaging materials, sanitary products, and book covers.

[0022] Specifically, the heat-insulating layer 33 is one of aerogel, ceramic fiber, polystyrene, and polyurethane. Aerogel is a nanoporous material with extremely low thermal conductivity and is an excellent heat-insulating material. Adding aerogel to the middle of the art paper can significantly improve the heat-insulating effect. Ceramic fiber is a high-temperature-resistant fiber material with good heat-insulating performance. It can be combined with the art paper through methods such as weaving, non-woven, or coating to form the heat-insulating layer 33. Foamed plastics such as polystyrene and polyurethane have low thermal conductivity and can be used as the heat-insulating layer 33. They can be added to the middle of the art paper through foaming or molding processes. Adding the heat-insulating layer 33 can make the art paper insulate heat to a certain extent and is suitable for fields that require heat insulation, such as insulation boxes, heat-insulating materials, and building insulation.

[0023] Specifically, the ink absorption layer 34 is one of plant fibers, polyvinyl alcohol, and polyacrylate. Plant fibers are one of the main components of paper and have good ink absorption performance. By optimizing the ratio and treatment method of plant fibers, the ink absorption ability of paper can be improved. Polyvinyl alcohol, polyacrylate, etc. can be used in combination with other materials to improve the surface performance and ink absorption ability of paper, forming the ink absorption layer 34.

[0024] Specifically, the anti-static layer 35 is one of conductive fibers, polyaniline, and polyacetylene. Conductive fibers such as carbon fibers and metal fibers can be added to the Xuan paperboard to provide a conductive path and reduce the generation of static electricity. The conductive fibers can be interwoven with the paper fibers or combined with the paper by means of composite. Polyaniline, polyacetylene, etc. have good electrical conductivity and can be used to prepare the anti-static layer 35. They can be deposited on the paper surface or form a composite structure with the paper by chemical or physical methods. Adding the anti-static layer 35 can prevent static electricity from adsorbing dust, paper scraps and other sundries, keep the paper clean and tidy, reduce the interference of static electricity on the printing process, improve the printing quality and stability, prevent the damage of static discharge to sensitive electronic devices, and improve the processing performance of the paper, such as preventing paper jams, sticking and other problems.

[0025] Specifically, the flame retardant layer 36 is one of glass fibers and ceramic fibers. Ceramic fibers are a kind of inorganic fiber material with high temperature resistance. They can be compounded with paper to form a ceramicized flame retardant layer, improving the fire resistance and flame retardant grade of the paper. Glass fibers are also a commonly used flame retardant material. They can enhance the strength of the paper and play a role in heat insulation and flame retardancy in case of fire. Adding the flame retardant layer can improve the flame retardant performance of the paper, reduce the risk of fire, increase the safety of the paper, prevent the spread and diffusion of fire, and meet specific fire prevention requirements and standards, such as the requirements in the fields of building materials, packaging materials, etc.

[0026] Furthermore, the connecting layer 4 is one of adhesives or hot melt adhesives. Adhesives are one of the most commonly used materials for the connecting layer. They can firmly bond different layers together and provide good connection strength. The choice of adhesives should be based on specific application requirements, such as water resistance, heat resistance, adhesiveness, etc. Hot melt adhesives are a kind of adhesives that become liquid when heated and solidify to form a connection after cooling. They are often used in automated production processes and can quickly and firmly connect each layer. The connecting layer 4 should be able to provide sufficient strength to ensure that each layer does not delaminate or separate during use, and is easy to process and handle, adapting to the production process and equipment requirements of the Xuan paperboard.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
