DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings:

[0022] like Figures 1-5 As shown, the embodiment provides an anti-aging and durable reflective film, including an elastic core layer 1. The elastic core layer 1 is the core part of the reflective film as a whole, and provides the reflective film as a whole with necessary elasticity and toughness, so that the entire reflective film material can be deformed and restored to its original state when subjected to external force, thereby improving the anti-wrinkle effect of the reflective film as a whole. Anti-aging layers 2 are fixedly installed on both sides of the elastic core layer 1, so as to prevent the reflective layer as a whole from being damaged by environmental factors such as ultraviolet rays, oxidation, and humidity, thereby extending the service life of the reflective film as a whole. An anti-tear reinforcement layer 3 is fixed on one side of the anti-aging layer 2, and the anti-tear reinforcement layer 3 enhances the tear resistance of the reflective film as a whole. The tear-resistant layer 3 has a tear-resistant performance, so that it is not easily damaged when facing sharp objects or strong pulling. An anti-fouling oleophobic layer 4 is fixed on the tear-resistant reinforcement layer 3. The anti-fouling oleophobic layer 4 makes the surface of the reflective film have self-cleaning ability, so that it is not easily stained with stains and oil, and is easy to clean. The anti-fouling oleophobic layer 4 is coated with a reflective coating. An anti-discoloration stabilizing layer 5 is fixedly installed on the anti-aging layer 2 on the other side to protect the internal layers of the reflective film from color changes caused by ultraviolet radiation and maintain the appearance stability and aesthetics of the material. An antibacterial and anti-mildew layer 6 is fixed on the anti-discoloration stabilizing layer 5 to inhibit the growth of bacteria and mildew in the reflective film and keep the reflective film hygienic and clean.

[0023] The elastic core layer 1 is made of elastic fibers. As a key component of the reflective film, the elastic core layer 1 is made of carefully selected elastic fibers that are carefully woven or interwoven. These elastic fibers are not only highly elastic, but also have good resilience and durability, ensuring that the core layer can quickly adapt and recover to its original state when subjected to external forces, maintaining the stability and integrity of the structure. At the same time, its excellent anti-fatigue performance enables the elastic core layer 1 to maintain excellent elastic performance in long-term use, allowing the reflective film to meet various high-demand application scenarios.

[0024] The anti-aging layer 2 is made of fluorocarbon resin, which has excellent weather resistance and chemical stability. Fluorocarbon resin can effectively resist the erosion of external factors such as ultraviolet rays, extreme temperatures, acid and alkali corrosion, and ensure the long-term stability of the surface and internal structure of the reflective film. Even in harsh environmental conditions, it can maintain bright colors and unfailing performance, thereby greatly extending the service life of the composite material.

[0025] The tear-resistant reinforcement layer 3 includes a first connection layer 301 and a second connection layer 302. The first connection layer 301 is fixedly connected to the second connection layer 302. A transverse reinforcement wire 303 is fixedly embedded in the first connection layer 301, and a longitudinal reinforcement wire 304 is fixedly embedded in the second connection layer 302. Both the transverse reinforcement wire 303 and the longitudinal reinforcement wire 304 are made of polyester fiber. The first connection layer 301 and the second connection layer 302 are tightly fixed by high-strength connection technology to form a solid mesh structure. The transverse reinforcement wire 303 is embedded in the first connection layer 301, and the longitudinal reinforcement wire 304 is embedded in the second connection layer 302. These reinforcement wires are made of high-strength polyester fiber and have excellent tensile strength and wear resistance. This criss-cross reinforcement design effectively improves the overall tear resistance of the reflective film and ensures that the integrity and stability of the reflective film structure can be maintained under extreme use conditions.

[0026] The antifouling oleophobic layer 4 is made of polymethyl methacrylate, and a perfluoropolyether coating is coated on the antifouling oleophobic layer 4. The antifouling oleophobic layer 4 is based on high-quality polymethyl methacrylate material, which itself has the characteristics of smooth surface and easy cleaning. In order to further improve its antifouling oleophobic performance, a layer of perfluoropolyether coating is coated on the surface of the antifouling oleophobic layer 4. Perfluoropolyether has extremely low surface energy and can effectively resist the adhesion of various stains and oil stains, making the surface of the composite material not only easy to clean, but also able to keep it clean for a long time. This double protection design provides the reflective film with excellent antifouling oleophobic performance and extends the service life and aesthetics of the reflective film product.

[0027] The anti-discoloration stabilizing layer 5 is made of PETG tough polyester. Due to its excellent toughness, PETG tough polyester can effectively resist external impacts. Due to its stable chemical properties, it can effectively prevent color changes caused by ultraviolet rays and other environmental factors, ensuring that the reflective film maintains its appearance for a long time and avoids affecting the reflective effect.

[0028] The antibacterial and mildew-proof layer 6 includes a connecting inner layer 601 and a connecting outer layer 602. Micropores are provided on both the connecting inner layer 601 and the connecting outer layer 602. An attaching core layer 603 is arranged between the connecting inner layer 601 and the connecting outer layer 602. An antibacterial agent is attached to the attaching core layer 603. The antibacterial and mildew-proof layer 6 is composed of the tightly connected connecting inner layer 601 and the connecting outer layer 602. The connecting inner layer 601 and the connecting outer layer 602 are provided with micropores to achieve the dual effects of ventilation and protection. The attaching core layer 603 is firmly placed between the connecting inner layer 601 and the connecting outer layer 602, and an efficient antibacterial agent is cleverly attached thereto. These antibacterial agents are continuously and evenly released to the surface and periphery of the material through the micropores, forming a powerful protective net to effectively inhibit the growth and reproduction of microorganisms such as bacteria and molds, providing comprehensive and long-term sanitary protection for the reflective film.
