Description

Technical Field

[0001] This utility model relates to the field of traffic facility technology, and in particular to a textured, anti-slip, reflective traffic marking line. Background Technology

[0002] Pedestrian crossings are traffic markings used to indicate the paths where pedestrians are permitted to cross the road under certain conditions, and also to warn drivers of motor vehicles to pay attention to pedestrians and non-motorized vehicles crossing the street. They can effectively protect pedestrians and non-motorized vehicles and reduce the risk of accidents. Large pedestrian crossings are usually painted at road intersections and sections of road where pedestrians frequently cross the road.

[0003] Depending on the materials and construction techniques, road markings are classified into hot-melt, solvent-based, and reaction-film-based types. Among them, hot-melt markings are the most widely used due to their simple construction process and low material cost. These markings involve heating and melting petroleum resin hot-melt paint, applying it to the road surface, and then sprinkling glass microbeads onto the surface. However, these markings have relatively weak anti-skid properties, especially in rainy or snowy weather. In areas with large areas marked, such as pedestrian crossings, pedestrians and non-motorized vehicles frequently slip and fall, affecting road safety.

[0004] According to the theory of friction, the insufficient friction between the rubber material of wheels and shoe soles and hot-melt road markings is due to: 1. Insufficient adhesion friction between petroleum resin, glass microspheres and rubber materials; 2. The road marking surface is flat and smooth, lacking texture, resulting in insufficient hysteresis friction between the road markings and rubber; 3. In rainy or snowy weather, the flat road markings cause the formation of a water film on the surface, wetting the interface between the rubber and the road markings, further reducing the adhesion friction between them.

[0005] In view of this, based on years of experience in production and design in this and related fields, the inventor has designed a textured, anti-slip, reflective traffic marking line through repeated experiments in order to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a textured, anti-slip, reflective traffic marking line that can effectively improve the anti-slip performance of traffic marking lines.

[0007] To achieve the above objectives, this utility model proposes a textured anti-skid reflective traffic marking line, wherein the textured anti-skid reflective traffic marking line includes a transparent wear-resistant layer, a textured reflective layer and an adhesive layer arranged sequentially from top to bottom. The transparent wear-resistant layer and the textured reflective layer contain a plurality of glass microspheres. The cross-section of the textured reflective layer has a square wave structure. The adhesive layer is adhered to the road surface.

[0008] As described above, the textured anti-slip reflective traffic marking line includes a plurality of convex portions and a plurality of concave portions, wherein the convex portions and the concave portions are arranged alternately to form the square wave structure, and the width of the concave portions is the same as the width of the convex portions.

[0009] As described above, the textured anti-slip reflective traffic marking line has a depth range of 1mm-2mm and a width range of 5mm-10mm.

[0010] As described above, the textured anti-slip reflective traffic marking line, wherein the length direction of the protrusion is perpendicular to the length direction of the road surface.

[0011] The textured anti-slip reflective traffic marking line described above, wherein the protrusion is wavy along its length.

[0012] As described above, the textured anti-slip reflective traffic marking line, wherein the transparent anti-wear layer is coated on the upper surface of the textured reflective layer and undulates along the square wave structure.

[0013] The textured, anti-slip, reflective traffic marking lines described above, wherein the surface of the transparent, abrasion-resistant layer is adhered with multiple glass microbeads.

[0014] The textured anti-slip reflective traffic marking line described above, wherein the surface of the transparent anti-wear layer is a rough surface.

[0015] As described above, the textured, anti-slip, reflective traffic marking line is wherein the adhesive layer is a room-temperature liquid pressure-sensitive adhesive layer.

[0016] The textured anti-slip reflective traffic marking line described above is a pedestrian crossing line.

[0017] Compared with the prior art, the present invention has the following features and advantages:

[0018] This invention proposes a textured anti-skid reflective traffic marking. By setting a textured reflective layer with a square wave structure on the road surface, the square wave structure of the textured reflective layer quickly drains rainwater and snow, preventing the formation of a water film between the tire and the textured anti-skid reflective traffic marking, thus significantly improving the anti-skid ability of the textured anti-skid reflective traffic marking under wet conditions. At the same time, both the transparent wear-resistant layer and the textured reflective layer of the textured anti-skid reflective traffic marking contain glass microspheres for reflection. The glass microspheres, which are gradually exposed as the textured anti-skid reflective traffic marking wears down, maintain the surface roughness and retroreflective performance of the textured anti-skid reflective traffic marking, thereby enhancing safety while ensuring the reflective effect of the marking throughout its entire life cycle.

[0027] The details of this utility model can be more clearly understood by referring to the accompanying drawings and the description of specific embodiments. However, the specific embodiments of this utility model described herein are for illustrative purposes only and should not be construed as limiting the utility model in any way. Under the teachings of this utility model, those skilled in the art can conceive of any possible modifications based on this utility model, and these should all be considered to fall within the scope of this utility model.

[0028] Unless otherwise defined, the directions such as up, down, left, and right mentioned in this document refer to those shown in this utility model. Figure 1 The directions of up, down, left, and right are used as a reference, and will be explained here.

[0029] like Figure 1 and Figure 2 As shown, this utility model proposes a textured anti-skid reflective traffic marking line 10, which includes a transparent anti-wear layer 4, a textured reflective layer 2 and an adhesive layer 3 arranged sequentially from top to bottom. The transparent anti-wear layer 4 and the textured reflective layer 2 contain a plurality of glass microspheres 1. The cross-section of the textured reflective layer 2 has a square wave structure, and the adhesive layer 3 is adhered to the road surface.

[0030] The textured anti-skid reflective traffic marking line 10 proposed in this utility model improves the anti-skid ability of the textured anti-skid reflective traffic marking line 10 under wet conditions by setting a textured reflective layer 2 with a square wave structure on the road surface. The square wave structure of the textured reflective layer 2 can quickly drain rain and snow water, avoiding the formation of a water film between the tire and the textured anti-skid reflective traffic marking line 10. At the same time, both the transparent wear-resistant layer 4 and the textured reflective layer 2 of the textured anti-skid reflective traffic marking line 10 are provided with glass microspheres 1 for reflection. The glass microspheres 1 with a gradient distribution inside are gradually exposed as the textured anti-skid reflective traffic marking line 10 wears, always maintaining the surface roughness and retroreflective performance of the textured anti-skid reflective traffic marking line 10, thereby enhancing safety while ensuring the reflective effect of the marking line throughout its entire life cycle.

[0031] In an optional embodiment of this invention, the textured reflective layer 2 includes multiple protrusions 21 and multiple concave portions 22, which are arranged alternately to form a square wave structure. The width of the concave portions 22 is the same as the width of the protrusions 21. The advantage of using a square wave cross-section in the textured reflective layer 2 is that the sharp edges of the protrusions 21 can pierce the water film structure between the tire and the textured anti-skid reflective traffic marking line 10, quickly cutting off the continuity of the water film. This facilitates direct contact between the tire and the transparent anti-wear layer 4 of the textured anti-skid reflective traffic marking line 10, increasing the friction between them. Furthermore, the square wave cross-section, formed by the alternating arrangement of concave portions 22 and protrusions 21, makes the top surface of the square wave structure flat, ensuring that the non-motorized vehicle's trajectory is not disturbed. Simultaneously, the grooves in the concave portions are used for rapid drainage, preventing the formation of a water film.

[0032] In this embodiment, the square wave-shaped protrusions 21 and concave sections 22 are designed with equal widths, ensuring drainage efficiency while achieving uniform force distribution. Furthermore, the top surface of the protrusions 21 is flat and matches the size of the non-motorized vehicle tires, avoiding interference with the driving trajectory caused by traditional raised or wave-shaped textures, ensuring uniform wear on the pedestrian crossing lines, and guaranteeing the reflective effect of the textured anti-slip reflective traffic marking lines 10; the equal-width concave sections 22 form a regular drainage network, disrupting the continuity of the water film and significantly improving the adhesive friction and hysteresis friction of the wet and slippery road surface.

[0033] In one optional example of this embodiment, the depth of the recess 22 ranges from 1 mm to 2 mm, and the width of the recess 22 ranges from 5 mm to 10 mm.

[0034] In one optional embodiment of this implementation, the length direction of the protrusion 21 is perpendicular to the length direction of the road surface. The protrusion 21 extends laterally along the road, and its structure, perpendicular to the longitudinal travel direction of the non-motorized vehicle tire, increases the lateral engagement area between the tire and the road marking, significantly improving lateral friction and effectively suppressing non-motorized vehicle skidding and loss of control. This is particularly suitable for slippery road sections such as curves and slopes, balancing anti-skid safety with drainage efficiency. Furthermore, the contact relationship between the protrusion 21 and the road surface further optimizes the mechanical properties and drainage path of the textured anti-skid reflective traffic marking 10.

[0035] In one alternative example, the protrusion 21 is wavy along its length, forming a multi-directional interlocking structure and a drainage channel aligned with the driving direction. Water can be quickly guided away from the contact interface along the wavy recess 22, further enhancing anti-skid performance. Simultaneously, the wavy recess 22 forms a continuous drainage path. Utilizing Pascal's principle, when the tire contacts the anti-skid reflective traffic marking 10, the water between the tire and the anti-skid reflective traffic marking 10 is squeezed out by the tire and discharged at the fastest speed along the straight section of the recess 22, preventing water film retention. Furthermore, the coefficient of friction between the tire rubber and the parallel tread pattern is greater than the coefficient of friction between the tire rubber and the cross tread pattern. Therefore, the parallel wavy tread structure has excellent drainage and anti-skid effects, making it a relatively ideal tread structure.

[0036] Preferably, the protrusion 21 is in the shape of a right-angled wavy line. Under the same cross-sectional area, the water flow rate of a straight-line textured surface is faster than that of a non-straight-line textured surface, and the water drainage speed is also faster. In an optional embodiment of this invention, a transparent anti-wear layer 4 is coated on the upper surface of the textured reflective layer 2 and undulates along a square wave structure, forming a flat protective layer on the top of the protrusion 21. The design of the transparent anti-wear layer 4 undulating along the square wave structure allows it to adhere tightly to the textured reflective layer 2, ensuring that both the protrusion 21 and the recess 22 receive uniform protection, avoiding structural failure caused by localized wear.

[0037] In one optional embodiment of this utility model, a plurality of glass microbeads 1 are adhered to the surface of the transparent anti-wear layer 4. In addition to increasing the reflectivity of the textured anti-slip reflective traffic sign line 10, the glass microbeads 1 also form a plurality of micro-protrusions on the surface of the transparent anti-wear layer 4, thereby increasing the anti-slip performance of the transparent anti-wear layer 4.

[0038] In one optional embodiment of this utility model, the glass microspheres 1 are preferably made of high refractive index glass with a refractive index of 1.8-1.9, such as titanium borosilicate glass or barium titanate glass.

[0039] In one optional embodiment of this invention, the refractive index of the glass microspheres 1 should not exceed 2.

[0040] In one optional embodiment of this invention, the glass microspheres 1 have good transmittance in the wavelength range of 300nm-2500nm and have no absorption peaks at 940nm and 1550nm, making them easy for the human eye and lidar to clearly identify.

[0041] In one optional embodiment of this utility model, the surface of the transparent anti-wear layer 4 is a rough surface, which works synergistically with the glass microspheres 1 that are partially exposed on the surface and uniformly distributed to enhance the micro-interlocking effect between the marking and the tire and optimize the anti-skid performance.

[0042] In one optional embodiment of this utility model, the transparent anti-wear layer 4 is a high-performance transparent polyurethane layer with good light transmittance in the visible light range and the wavelengths commonly used in lidar.

[0043] In one optional embodiment of this utility model, the adhesive layer 3 is a room-temperature liquid pressure-sensitive adhesive layer containing nano-kaolin.

[0044] Furthermore, nano-kaolin is nano-kaolin treated with nano-calcium carbonate, nano-silica, and silane coupling agent. The nano-kaolin treated with silane coupling agent can enhance the bonding strength between acrylic resin and asphalt pavement, improve the shear strength at the bond between pedestrian crossings and asphalt pavement, and extend the service life of pedestrian crossings. The combined use of nano-calcium carbonate, nano-silica, and nano-kaolin further improves the durability of pedestrian crossings, making them particularly suitable for high-traffic areas.

[0045] In one optional embodiment of this utility model, the textured anti-slip reflective traffic marking line 10 is a pedestrian crossing line.

[0046] The detailed explanations of the above embodiments are intended only to explain the present invention so as to facilitate a better understanding of the present invention. However, these descriptions should not be construed as limiting the present invention for any reason. In particular, the various features described in different embodiments can be arbitrarily combined with each other to form other embodiments. Unless there is an explicit description to the contrary, these features should be understood to be applicable to any embodiment, and not limited to the described embodiments.
