Description

Technical Field

[0001] This utility model relates to the field of road markings, and in particular to an elastic matrix road marking anti-rolling structure. Background Technology

[0002] Road markings are an important component of transportation infrastructure, serving to guide vehicle movement, regulate traffic order, and ensure road traffic safety. Whether on bustling city streets, highways, or rural roads, clear and accurate road markings provide drivers with clear driving guidance, thereby improving road efficiency and reducing the probability of traffic accidents.

[0003] Currently used hot-melt road marking paints, while possessing certain wear resistance and initial adhesion, are hard and lack elasticity after curing. They cannot effectively buffer the impact of vehicles running over them, and under long-term repeated wheel rolling, they will wear down and fall off, thus affecting the visibility and clarity of the markings. Therefore, an elastic matrix road marking anti-rolling structure is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an elastic matrix road marking anti-rolling structure, which aims to improve the problem in the existing technology that "commonly used hot-melt road markings are hard and lack elasticity, and therefore will wear and fall off under long-term rolling, thus affecting the guiding function of the markings".

[0026] 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.

[0027] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an elastic substrate road marking anti-rolling structure, comprising a substrate bonding layer 9, which can tightly bond with the road surface, providing a stable foundation for the entire marking structure. A support component is provided at the top of the substrate bonding layer 9, including a mesh fabric 10. The mesh fabric 10 is configured as a wavy mesh with through holes. By configuring the mesh fabric 10 as a wavy mesh with through holes, the contact area with each layer is increased, improving the bonding effect. This allows the marking to better disperse stress when under load, enhancing the stability and deformation resistance of the entire marking structure. When a vehicle rolls over the marking, the mesh... The 10 mesh evenly distributes pressure to each layer, preventing any layer from being damaged by excessive pressure. This helps improve the anti-rolling performance of the road markings, making the entire structure more stable. The substrate bonding layer 9 is made of epoxy asphalt adhesive, which tightly fixes the entire anti-rolling structure to the road surface. This ensures that the road marking structure will not separate from the road surface under complex conditions such as long-term vehicle rolling, road surface temperature changes, and rain erosion, thus enhancing the anti-rolling effect of the road markings. The 10 mesh is made of glass fiber, which has high strength, corrosion resistance, and high temperature resistance. This increases the contact area with each layer, improves the bonding effect, and makes the entire structure more stable.

[0028] Furthermore, a waterproof layer 8 is provided at the top of the substrate bonding layer 9. The waterproof layer 8 is made of SBS modified bitumen waterproof membrane, which is composed of asphalt, rubber, and other composite materials. Its main function is to waterproof, prevent water from the road surface from penetrating into the marking, keep the internal layers dry, maintain the stability of material performance, and indirectly improve the overall anti-rolling effect of the marking and extend its service life. A stress-absorbing layer 7 is provided at the top of the waterproof layer 8. The stress-absorbing layer 7 is made of rubber asphalt, which is made by adding waste rubber powder to the base asphalt. When a vehicle rolls over the marking, the rubber asphalt can effectively disperse and absorb the stress generated by the vehicle due to its good flexibility and elasticity. The stress-absorbing layer 7 reduces the impact force it receives and reduces the risk of fatigue and cracking of the elastic substrate layer 6 due to long-term stress, which greatly improves the fatigue resistance of the marking and enhances its anti-rolling effect. An elastic substrate layer 6 is provided at the top of the stress-absorbing layer 7, a buffer layer 5 is provided at the top of the elastic substrate layer 6, and a reinforcing layer 4 is provided at the top of the buffer layer 5.

[0029] Furthermore, the reinforcing layer 4 is made of glass fiber, which has high strength and stiffness. In the marking structure, it mainly plays a reinforcing role, effectively improving the marking's tensile and tear resistance. The elastic matrix layer 6 is made of thermoplastic polyurethane elastomer, which has excellent elasticity, wear resistance, and aging resistance. When a vehicle runs over it, it can undergo elastic deformation to absorb the pressure energy applied by the vehicle. After the vehicle leaves, it can quickly return to its original shape, maintaining the marking's shape and integrity. The buffer layer 5 is made of polyurethane foam, which is lightweight and porous. While the elastic matrix layer 6 deforms, the buffer layer 5 can further buffer the impact force generated by the vehicle running over it. The buffer layer 5 helps to improve the marking's impact resistance, enhances the overall marking structure's anti-rolling effect, and extends the marking's service life.

[0030] Reference Figure 1 - Figure 3The top of the reinforcing layer 4 is equipped with a protective component, which includes a wear-resistant layer 3. The wear-resistant layer 3 is set on top of the reinforcing layer 4 and is made of silicon carbide reinforced epoxy resin coating material. The resin coating contains silicon carbide wear-resistant particles. Silicon carbide has high hardness and forms a coating with good wear resistance after bonding with the resin. During long-term vehicle operation, the wear-resistant layer 3 is in direct contact with the vehicle tires, resisting frequent tire friction. The top of the wear-resistant layer 3 is equipped with a reflective warning layer 2, which is made of reflective paint material containing glass microspheres. The reflective paint provides functions such as adhesion and color. The main function of the reflective warning layer 2 is to make the markings clearly visible by reflecting vehicle lights at night or in low light conditions, guiding vehicles to drive correctly and ensuring traffic safety.

[0031] Furthermore, an anti-slip layer 1 is provided at the top of the reflective warning layer 2. The anti-slip layer 1 is a resin coating material with added quartz sand. The quartz sand has a certain roughness and combines with the resin to form the anti-slip layer 1. It mainly increases the friction between the road surface and the vehicle tires, effectively preventing the vehicle from skidding. The substrate bonding layer 9, waterproof layer 8, stress absorption layer 7, elastic substrate layer 6, buffer layer 5, reinforcing layer 4, wear-resistant layer 3, reflective warning layer 2 and anti-slip layer 1 are all fixedly connected to the mesh cloth 10. Each layer is connected to the mesh cloth 10. The fiberglass mesh cloth 10, with its high strength and corrosion resistance, enhances the stability of the overall structure, just like the steel frame in a building. This allows each layer to work together to bear the force under the pressure of vehicles, enhancing the anti-rolling effect of the elastic substrate road markings.

[0032] Working Principle: During use, in the elastic matrix road marking anti-rolling structure, the matrix bonding layer 9, made of epoxy asphalt adhesive, tightly adheres to the road surface, ensuring the entire marking structure is stably attached and supported in complex environments. The mesh fabric 10, made of glass fiber with a corrugated through-hole pattern, connects to each layer, enhancing the bonding effect between layers. When vehicles roll over it, the pressure is evenly distributed to each layer, improving the overall structural stability and deformation resistance. The waterproof layer 8, made of SBS modified asphalt waterproof membrane, effectively prevents water from seeping into the road surface, keeps the internal layers dry, ensures stable material performance, and indirectly improves the anti-rolling effect. The stress-absorbing layer 7, made of rubber asphalt, absorbs and disperses the stress generated by vehicle rolling due to its good flexibility and elasticity, reducing the fatigue risk of the elastic matrix layer 6. The elastic matrix layer 6, made of thermoplastic polyurethane elastomer, absorbs energy through elastic deformation when vehicles roll over it, and returns to its original shape after the vehicles leave, maintaining the integrity of the marking shape.

[0033] Above the elastic matrix layer 6, the polyurethane foam buffer layer 5 further cushions the impact of vehicle rolling, helping to improve impact resistance. The fiberglass reinforcing layer 4 enhances the tensile and tear resistance of the road markings, stabilizing the entire structure. The wear-resistant layer 3, with silicon carbide-reinforced epoxy resin coating, directly faces the friction of vehicle tires. The high hardness of silicon carbide protects the underlying structure. The reflective warning layer 2, composed of reflective paint containing glass microspheres, reflects light at night or in low light conditions, guiding vehicles and ensuring safety, while also sharing some of the rolling pressure. The resin coating anti-slip layer 1, with added quartz sand, increases the friction between the road surface and tires, preventing vehicles from slipping and avoiding localized stress concentration that could damage the road markings. Each layer is fixedly connected to the mesh fabric 10, working together to share the force when vehicles roll over it, comprehensively improving the anti-rolling performance of the elastic matrix road markings, ensuring that the road markings remain in good condition during long-term use and continue to play their role in guiding traffic.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
