[0021] Reference Figures 1 to 3According to a first aspect of the present invention, a weather-resistant marking includes an adhesive layer 100, a substrate layer 200, a border layer 300, a protective film layer 400, and a release layer 500. The substrate layer 200 is connected to the top surface of the adhesive layer 100. A gap region 110 is formed between the outer edge of the substrate layer 200 and the outer edge of the adhesive layer 100. The border layer 300 includes an edge portion 310 and a protective edge portion 320. The edge portion 310 is bonded to the gap region 110, and the protective edge portion 320 is connected to the outer end of the edge portion 310 and extends downward along the thickness direction of the adhesive layer 100. The protective film layer 400 covers the top surface of the substrate layer 200 and the outer edge portion 310. The release layer 500 is disposed on the bottom surface of the adhesive layer 100. The adhesive layer 100 is prone to warping at its outer edge, which is often found between the adhesive layer 100 and the substrate layer 200. However, by providing a frame layer 300, the edge portion 310, and the protective edge portion 320 can cover the area of ​​the adhesive layer 100 near its outer edge and the outer wall, providing protection and slowing down environmental corrosion. Simultaneously, the L-shaped structure of the frame layer 300 provides rigidity, ensuring it remains straight and warp-free even if the adhesive at the edge of the adhesive layer 100 fails, meeting usage requirements. The protective film layer 400 covers the substrate layer 200 and the top surface of the edge portion 310, forming a continuous protective interface to prevent moisture, ultraviolet rays, and other substances from penetrating the interlayer structure from the top. Specifically, the outer edge of the substrate layer 200 is located inside the outer edge of the adhesive layer 100, forming a gap area 110, allowing the edge portion 310 of the frame layer 300 to be directly bonded to the surface of the adhesive layer 100, facilitating assembly. The frame layer 300 also prevents stress concentration at the junction of the adhesive layer 100 and the substrate layer 200. The edge protector 320 extends downwards, wrapping around the sidewalls of the adhesive layer 100. This not only prevents rainwater, dust, and other corrosive media from contacting the edge of the adhesive layer, but also inhibits deformation of the adhesive layer through its rigidity. The protective film layer 400 continuously covers the top of the substrate layer 200 and the frame layer 300, eliminating interlayer gaps and forming a complete protective interface to prevent media from penetrating the interlayer structure from the top. It effectively suppresses interlayer stress concentration caused by temperature changes, blocks environmental media from eroding the edges of the adhesive layer 100, and prevents moisture penetration from the top interface that leads to adhesive layer aging, as well as preventing yellowing caused by ultraviolet radiation. The edge of the substrate layer 200 is wrapped and fixed by the frame layer 300, preventing direct exposure to the external environment. The vertical barrier formed by the edge protector 320 significantly improves side protection capabilities and is less prone to warping under external forces.

[0022] In some embodiments of this invention, the border layer 300 is made of rigid plastic, and the Shore hardness of the border layer 300 is greater than that of the substrate layer 200. Specifically, the border layer 300 can be made of rigid PVC, while the substrate layer 200 can be made of soft PVC. The border layer 300 acts as a rigid frame to enclose the edge area of ​​the substrate layer 200, providing protection for the marking edges. When temperature changes cause material expansion, the harder border layer 300 constrains the lateral extension of the substrate layer 200 through its own deformation resistance. The hardness difference between the two materials causes a gradient attenuation of stress at the interface. The rigid border layer 300 can withstand the stress, while the substrate layer 200 absorbs residual stress through moderate elastic deformation. This mechanical distribution mode avoids fatigue failure of a single material under alternating stress, and the interface buffer zone formed by the hardness difference can compensate for the difference in the thermal expansion coefficients of the different materials.

[0023] Reference Figures 1 to 2 In some embodiments of this utility model, the edge portion 310 and the edge guard portion 320 are an integral structure. Specifically, the frame layer 300 can be integrally formed by hot pressing to create the edge portion 310 and the edge guard portion 320, simplifying the manufacturing process. This structure eliminates the seam gaps required for traditional split connections, allowing the frame layer 300 to form a seamless annular closed frame. This significantly improves the sealing performance of the frame layer 300 over the edge of the substrate layer 200, while also enhancing the overall structure's corrosion resistance and mechanical impact resistance in complex environments.

[0024] In some embodiments of this invention, the bottom surface of the frame layer 300 has an adhesive layer, the edge portion 310 extends to the substrate layer 200, and a portion of the edge portion 310 covers a portion of the substrate layer 200 near the edge with the adhesive layer. Specifically, the adhesive layer may be an adhesive material layer coated on the bottom surface of the frame layer 300, which serves to form a second adhesive interface between the frame layer 300, the substrate layer 200, and the adhesive layer 100. The edge portion 310 may extend horizontally towards the substrate layer 200 to the top surface of the substrate layer 200 to wrap around the edge of the substrate layer 200. This layered bonding of the edge portion 310 to the substrate layer 200 further protects and wraps around the substrate layer 200.

[0025] In some embodiments of this invention, the adhesive layer 100 is a foam adhesive layer. Specifically, it can be implemented using polyurethane foam or acrylic foam tape. This material has a porous structure, enabling it to undergo elastic deformation under pressure and absorb external stress through its pores. When changes in external temperature cause thermal expansion and contraction differences between the substrate layer 200 and the adhesive layer 100, the elastic deformation capability of the foam adhesive layer allows it to be compressed or rebound, thereby buffering stress concentration at the interface. The porous structure allows gas to escape during bonding, preventing air bubbles from causing poor contact at the bonding surface. In long-term use, the aging resistance of the foam material allows it to maintain the uniformity of the adhesive layer thickness even under ultraviolet light or chemical corrosion environments, preventing edge peeling caused by localized adhesive layer shrinkage.

[0026] Reference Figures 1 to 2 In some embodiments of this utility model, the edge protector 320 abuts against and is bonded to the sidewall of the adhesive layer 100. Specifically, the bottom surface of the edge protector 320 can also be bonded to the sidewall of the adhesive layer 100 through the adhesive layer, forming a tight fit through physical contact, which can further prevent moisture or corrosive substances from intruding from the side, and at the same time reduce the rate of adhesion attenuation of the adhesive layer 100 due to environmental erosion.

[0027] Reference Figure 3 In some embodiments of this utility model, the substrate layer 200 includes a PVC base layer 210 and a printing layer 220. The PVC base layer 210 refers to the polyvinyl chloride material layer that serves as the main supporting structure of the substrate layer 200, and the printing layer 220 refers to the coating layer that is attached to the surface of the PVC base layer 210 and carries the graphic information of the warning label. Specifically, it can be achieved by directly coating ink onto the surface of the PVC base layer 210 using screen printing or UV inkjet printing processes.

[0028] Reference Figure 3In some embodiments of this utility model, the substrate layer 200 further includes a reflective film layer 230 disposed on the surface of the printed layer 220. The reflective film layer 230 is provided with a surface film 231, a glass microsphere layer 232, a focusing layer 233, and a reflective layer 234 from top to bottom. Specifically, the surface film 231 refers to a transparent protective layer covering the outermost surface of the reflective film layer 230. The glass microsphere layer 232 refers to a reflective medium layer composed of uniformly distributed glass microspheres, which can be implemented using silica glass beads with a diameter of 50-150 micrometers, used for directional reflection of incident light. The focusing layer 233 refers to an optical structure layer disposed below the glass microsphere layer 232, which can be implemented using acrylic resin material to form a microprism array through an imprinting process, used to adjust the light propagation path to improve reflection efficiency. The reflective layer 234 refers to the metal coating located at the bottom of the reflective film layer 230, which can be achieved by vacuum-deposited aluminum film. It is used for secondary reflection of residual light that has not been reflected by the glass microsphere layer 232. Specifically, when external light enters the reflective film layer 230, the surface film 231 first transmits the light and filters ultraviolet rays. The transmitted light enters the glass microsphere layer 232 and undergoes refraction and total internal reflection, forming the first directional reflection. The light that is not completely reflected continues to propagate downwards to the focusing layer 233, where the geometry of the microprism array changes its propagation direction, causing it to converge again to the glass microsphere layer 232 for secondary reflection. Finally, the residual light that has not been reflected reaches the reflective layer 234 and undergoes a third reflection due to the high reflectivity of the metal coating. Through the synergistic effect of the three-layer reflective structure, light scattering loss is effectively reduced, while the protective effect of the surface film 231 on the internal optical structure ensures the long-term stability of the reflective performance. Compared with existing technologies, traditional reflective films only use a single glass microsphere layer 232 or metal reflective layer 234 structure, which is prone to problems such as limited reflection angle and severe light scattering under complex lighting conditions. This solution forms a composite reflective system by stacking a glass microsphere layer 232, a focusing layer 233 and a reflective layer 234. While maintaining the light transmittance of the surface film 231, it achieves multi-level reflection path optimization of incident light, and in particular solves the problem of reflection efficiency attenuation of low-angle incident light.

[0029] Reference Figure 3 In some embodiments of this utility model, the protective film layer 400 includes an anti-ultraviolet coating 410. The anti-ultraviolet coating 410 refers to a material layer that can absorb or reflect ultraviolet rays. Specifically, it can be achieved by using a polyurethane coating with added ultraviolet absorbers. By absorbing or scattering ultraviolet radiation, it reduces the direct effect of ultraviolet rays on the substrate layer 200.

[0030] In some embodiments of this invention, the bottom surface of the adhesive layer 100 is provided with venting texture. Venting texture refers to a regular or irregular uneven structure formed on the bottom surface of the adhesive layer 100, specifically a grid-like, wavy, or dot-matrix groove structure. This structure forms gas venting channels when the adhesive layer 100 is bonded to the target surface, allowing air to diffuse outwards along the texture gaps to prevent bubbling of the markings.
