Description

Technical Field

[0001] This utility model relates to the field of reflective strip technology, and in particular to a wear-resistant reflective strip. Background Technology

[0002] Reflective materials are widely used in road traffic, nighttime lighting, safety warnings, and personal protective equipment as key components to improve visibility and ensure the safety of personnel and equipment. They are applied to road markings, vehicle outlines, work clothes, and various warning devices. As society's requirements for traffic safety and nighttime work safety continue to increase, reflective strips not only need to have excellent reflective properties, but also need to maintain good structural stability and service life in complex and changing usage environments.

[0003] Currently, conventional reflective strips mostly employ a multi-layered composite structure, including a base layer, a reflective layer, and a protective layer. However, existing technologies still have many shortcomings. For example, the bonding force between the base layer and the transition layer is weak, making them prone to peeling or detachment under long-term friction or external force; glass microspheres are mostly directly adhered to the surface, exhibiting poor wear resistance and easily leading to a decrease in reflective performance due to wear or impact; simultaneously, traditional materials are prone to cracking under repeated bending or stretching, resulting in overall structural failure. These problems seriously affect the service life and practical application effect of reflective strips. Therefore, there is an urgent need for a reflective strip with a reasonable structural design, excellent wear resistance, peel resistance, and good environmental adaptability to meet the higher requirements for the stability and reliability of reflective materials under complex working conditions. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wear-resistant reflective strip. This strip uses a honeycomb interlocking structure and wedge-shaped blocks to fix glass microspheres, thereby enhancing its anti-peeling properties. The elastic metal foil interlayer absorbs impact energy, adapts to deformation, and prevents cracking. The glass microspheres act as "wear-resistant pioneers" to protect the microprisms, achieving dual reflective protection and significantly improving wear resistance and environmental adaptability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant reflective strip, comprising a base layer, a transition layer provided at the upper end of the base layer, a wedge-shaped block fixedly connected inside the transition layer, glass microspheres fixedly connected to the top of the wedge block, an elastic honeycomb interlayer provided at the upper end of the transition layer, a wear-resistant layer provided at the upper end of the elastic honeycomb interlayer, the wear-resistant layer being polycarbonate, a microprism fixedly connected to the top of the inner wall of the wear-resistant layer, and the glass microspheres and microprisms being arranged at intervals.

[0006] Furthermore, the base layer is made of polyester fiber, and the surface of the base layer has honeycomb pits.

[0007] Furthermore, the transition layer is made of elastic polyurethane, and the lower end of the transition layer is provided with honeycomb protrusions that match the honeycomb pits.

[0008] Furthermore, the elastic honeycomb interlayer is an elastic metal foil that can absorb impact energy through its own deformation.

[0009] Furthermore, a sealing strip is fixedly connected to the outer wall of the base layer, and an installation block is fixedly connected to the outer wall of the sealing strip.

[0010] Furthermore, the mounting block has mounting holes inside for mounting reflective strips.

[0011] Furthermore, the top of the glass microsphere is slightly higher than the microprism, and the upper outer wall of the glass microsphere is wrapped inside the wear-resistant layer.

[0012] This utility model has the following beneficial effects: 1. In this utility model, a honeycomb structure interlocking design ensures a tight bond between the base layer and the transition layer. Simultaneously, glass microspheres are fixed to the elastic polyurethane layer using a wedge-shaped interlocking method, effectively enhancing its anti-peeling ability under long-term friction and external force. Furthermore, the wear-resistant layer uses high-strength, high-transmittance polycarbonate material, which not only possesses excellent impact resistance and heat resistance but also significantly improves the overall wear-resistant lifespan without affecting the reflective effect, greatly extending the service life of the reflective strip.

[0013] 2. In this invention, by incorporating an elastic metal foil interlayer, energy can be absorbed during external impacts or friction, reducing structural damage. Simultaneously, it adapts to the bending and tensile deformation of the substrate, preventing structural cracking. The top of the glass microspheres is slightly higher than the microprisms, acting as a "wear-resistant vanguard" to preferentially withstand wear and protect the microprism structure below. Even after the microspheres wear down, the microprisms below maintain high-efficiency reflectivity, forming a "double reflective guarantee." This design ensures the reflective strip maintains stable performance under harsh environments or frequent use, exhibiting strong adaptability and high reliability. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 2 , Figure 3 and Figure 5 An embodiment of this utility model provides: a wear-resistant reflective strip, including a base layer 1, which is made of polyester fiber, with honeycomb pits 8 formed on the surface of the base layer 1, a transition layer 2 at the upper end of the base layer 1, which is made of elastic polyurethane, and a honeycomb protrusion 9 at the lower end of the transition layer 2 that matches the honeycomb pits 8, a wedge block 3 fixedly connected inside the transition layer 2, a glass microsphere 4 fixedly connected to the top of the wedge block 3, an elastic honeycomb interlayer 5 at the upper end of the transition layer 2, which is made of elastic metal foil and can absorb impact energy through its own deformation, a wear-resistant layer 6 at the upper end of the elastic honeycomb interlayer 5, which is made of polycarbonate, a microprism 7 fixedly connected to the top of the inner wall of the wear-resistant layer 6, and the upper outer wall of the glass microsphere 4 wrapped inside the wear-resistant layer 6.

[0018] Specifically, this reflective strip adopts a multi-layer composite structure design, possessing excellent wear resistance, peel resistance, and elastic cushioning performance, making it suitable for various complex environments. The base layer 1 of the reflective strip is made of high-strength polyester fiber material, exhibiting good durability and dimensional stability. Its surface is processed with micron-level honeycomb-like pits using high-precision laser engraving technology. The transition layer 2, made of elastic polyurethane material, fills the surface of the base layer 1, with its bottom forming honeycomb-like protrusions that tightly fit the honeycomb pits 8, thus achieving a strong bond between the transition layer 2 and the base layer 1, significantly improving the overall structural stability and peel resistance. Glass microspheres 4 are embedded inside the transition layer 2 through a wedge-shaped block 3 structure at the bottom, further enhancing its resistance to detachment under external force. The upper outer wall of the glass microspheres 4 is wrapped inside the wear-resistant layer 6. The wear-resistant layer 6 is made of high-transmittance polycarbonate material, possessing good impact resistance, heat resistance, and wear resistance, protecting the internal structure without affecting the reflective effect. Compared with traditional materials, the service life of this wear-resistant layer 6 can be increased by more than 30%. The elastic honeycomb interlayer 5, composed of elastic metal foil, is located below the wear-resistant layer 6. It does not affect the reflectivity of the glass microspheres and microprisms. When the reflective strip is subjected to external friction or impact, this interlayer can absorb energy through its elastic deformation, providing cushioning and protection. Simultaneously, it can adapt to the bending and stretching changes of the substrate, effectively preventing structural cracking and improving the adaptability and durability of the reflective strip.

[0019] Reference Figure 1 , Figure 2 and Figure 4 Glass microspheres 4 and microprisms 7 are arranged alternately, with the top of the glass microspheres 4 slightly higher than the microprisms 7. A sealing strip 10 is fixedly connected to the outer wall of the base layer 1, and an installation block 11 is fixedly connected to the outer wall of the sealing strip 10. An installation hole 12 is opened inside the installation block 11 for installing reflective strips.

[0020] Specifically, the top of the glass microspheres 4 protrudes slightly above the microprism 7 structure, allowing them to withstand wear first during friction, thus acting as a "wear-resistant pioneer" and effectively protecting the microprism 7 below. Even as the glass microspheres 4 gradually wear down, the microprism 7 below maintains its high reflectivity, achieving "double reflectivity protection." The microprism 7 employs a polyhedral structure with a smaller top and a larger bottom. This design not only enhances the bond between it and the wear-resistant layer 6 but also effectively resists peeling under impact or friction, improving overall structural strength and reflectivity stability. To further enhance protective performance, the entire reflective strip's outer wall is wrapped by a sealing strip 10, forming a good seal to prevent dust, moisture, and other external factors from affecting the internal structure. Furthermore, the reflective strip can be flexibly installed in various positions via the mounting holes 12 on the mounting block 11, facilitating construction and maintenance.

[0021] In summary, this reflective strip, through its multi-layer composite structure design and innovative technologies such as honeycomb interlocking, elastic buffering, wear-resistant core, and dual reflectivity, significantly improves its wear resistance, peel resistance, and reflective stability in complex environments, demonstrating good practicality and application prospects.

[0022] Working Principle: The base layer 1 of this reflective strip is made of polyester fiber, with micron-level honeycomb pits 8 laser-engraved on its surface. The transition layer 2 is made of elastic polyurethane material, which, after filling the surface of the base layer 1, forms honeycomb protrusions 9 at the lower end that fit with the honeycomb pits 8, making the transition layer 2 and the base layer 1 more tightly bonded. Glass microspheres 4 are embedded in the transition layer 2 through wedge-shaped blocks 3 at the lower end, enhancing the anti-peel performance. The microprisms 7 are polyhedrons with a small upper end and a large lower end, enhancing the bonding force with the wear-resistant layer 6. This structure significantly improves the anti-peel performance of the wear-resistant layer 6, glass microspheres 4, and microprisms 7 under friction and impact, increasing the wear life by more than 30%. The wear-resistant layer 6 is made of polycarbonate, which has strong impact resistance, light transmission, and heat resistance, and does not affect the reflective performance while possessing strong wear resistance. The elastic honeycomb interlayer 5 uses elastic metal foil. When the reflective strip is subjected to external friction or impact, the elastic honeycomb interlayer 5 absorbs energy through its own deformation. At the same time, it can adapt to the bending and tensile deformation of the substrate, reducing structural cracking. The top of the glass microbeads 4 is slightly higher than the microprisms 7, reducing the frictional stress per unit area. At the same time, it acts as a "wear-resistant pioneer" to protect the microprisms 7 below. When the glass microbeads 4 are worn, the microprisms 7 below can still maintain high reflectivity, achieving double reflective protection. The outer wall of the entire reflective strip is wrapped by the sealing strip 10, forming further protection. The reflective strip can be installed in any position through the mounting holes 12 on the mounting block 11.
