Description

Technical Field

[0001] This utility model relates to the field of reflective markings, and in particular to a reflective marking for rainy nights with an anti-slip coating. Background Technology

[0002] Road markings are one of the directional signs used to plan and divide roads. Traffic departments use markings to divide roads into one-way and two-way lanes, and use markings to indicate the function of each lane, such as going straight, turning, and making a U-turn. Vehicles can drive safely and smoothly under the guidance of road signs and road markings. However, in rainy weather, rainwater will accumulate on the ground and form a layer of water film on the road surface. When looking at the ground from inside the car, the reflection of the road ahead makes it impossible to see the road markings and the directional signs on the ground, which greatly interferes with the driver's vision. This can easily lead to traffic disorder, and during rush hour, traffic congestion or even traffic paralysis is very likely to occur.

[0003] Traditional pre-formed reflective road markings consist of a basic reflective layer, a substrate layer, and an adhesive layer. The adhesive layer has a limited thickness, generally less than 1 mm. However, concrete pavements are relatively rough, and the insufficient thickness of the adhesive layer results in poor adhesion to the ground. With prolonged use, the pressure of vehicle wheels, and the influence of harsh natural environments, reflective road markings pasted on the road surface are prone to peeling and falling off, resulting in a short service life. Utility Model Content

[0004] The purpose of this invention is to provide a reflective marker with anti-slip coating for rainy nights, which solves the problems of existing reflective marker strips that are prone to curling and falling off, and have a short service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a reflective line for rainy nights with anti-slip coating, comprising an adhesive layer, a coating base layer and a surface protective layer, wherein the adhesive layer is disposed at the bottom of the coating base layer, the interior of the coating base layer is uniformly mixed with glass microspheres, the surface protective layer covers the coating base layer, the cross-section of the coating base layer is wavy, and the two sides of the coating base layer are provided with horizontal transition steps;

[0006] Reflective lines are provided between the coating base layer and the surface protective layer. A coating layer is provided inside the coating base layer, and a water-absorbing and expanding layer is provided at the upper end of the coating layer.

[0007] As a further description of the above technical solution: edge adhesive layers are provided at both ends below the coating layer, and flexible strips are provided on the inner side of the edge adhesive layers.

[0008] As a further description of the above technical solution: a strip-shaped sealing film bag is provided on the inner side of the flexible strip, an isolation layer is provided on the surface of the flexible strip and the strip-shaped sealing film bag, pressure-sensitive adhesive is coated between the flexible strip and the isolation layer, and the adhesion between the flexible strip and the coating substrate is greater than the adhesion between the flexible strip and the isolation layer.

[0009] This utility model has the following beneficial effects:

[0010] Compared to existing technologies, this rain-reflective marking material with anti-slip coating features a protective surface layer (polyurethane varnish) applied to the outer surface of glass microspheres. This protective layer provides long-term protection for the internal glass microspheres without affecting their reflective properties, extending their lifespan and effectively avoiding the hassle of repeated application. Furthermore, the addition of a matting agent to the polyurethane varnish layer effectively prevents glare caused by the glass microspheres' reflection. The polyurethane varnish layer, upon curing, forms a rough surface, increasing the friction between the vehicle tires and the marking paint, preventing vehicle slippage in rainy weather and improving travel safety.

[0011] Compared with existing technologies, this reflective road marking with anti-slip coating changes the original raised arc-shaped marking to a wavy marking. It retains the wear resistance of the original marking, overcomes the defect that the middle part of the raised arc-shaped marking wears out first, and at the same time, it uses the water absorption and expansion properties of the water-absorbing and expanding layer to increase the protrusion of the marking in rainy weather, thereby increasing its anti-slip properties. This ensures that drivers can see the road marking clearly in rainy weather, effectively prevents traffic congestion, and thus ensures the driving safety of drivers.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-2 This utility model provides an embodiment of a reflective road marking with anti-slip coating for rainy nights, comprising an adhesive layer 3, a coating base layer 2, and a surface protective layer 6. The adhesive layer 3 includes an edge adhesive layer 10 located at the bottom of the transition step 5. The edge adhesive layer 10 is made of room temperature liquid pressure-sensitive adhesive and contains a small amount of lithium polysilicate, nano-calcium carbonate, nano-silica, and nano-kaolin. Among them, lithium polysilicate and nano-kaolin can work synergistically to promote the entry of acrylic resin into the capillaries of the asphalt pavement, chemically cross-link with the asphalt pavement, seal the capillaries of the asphalt pavement, improve the adhesion between the road marking and the asphalt pavement, improve the impact resistance of the road marking, and extend the service life of the road marking. The combined use of nano-calcium carbonate, nano-silica, and nano-kaolin further improves the wear resistance, rutting resistance, and impact resistance of the road marking. The surface protective layer 6 is a polyurethane varnish layer, which can provide long-term protection for the internal glass microspheres 4 without affecting their reflective properties, thus extending the service life of the glass microspheres 4 and effectively avoiding the trouble caused by repeated construction. Furthermore, the addition of a matting agent to the polyurethane clear coat effectively avoids the glare effect caused by the reflection of glass microspheres. The polyurethane clear coat forms a rough surface during curing, which increases the friction between the vehicle tires and the marking paint, preventing the vehicle from slipping in the rain and improving travel safety.

[0020] The adhesive layer 3 is set at the bottom of the coating base layer 2. Glass microspheres 4 are uniformly mixed inside the coating base layer 2. The surface protective layer 6 covers the coating base layer 2. The cross section of the coating base layer 2 is wavy. Horizontal transition steps 5 are provided on both sides of the coating base layer 2.

[0021] A reflective marking line 1 is provided between the paint base layer 2 and the surface protective layer 6. The paint base layer 2 has a paint layer 11 inside, and a water-absorbing and expanding layer 12 is provided on the upper end of the paint layer 11. The water-absorbing and expanding layer 12 is made of water-absorbing and expanding material. In rainy weather, the water-absorbing and expanding layer 12 can quickly absorb the rainwater around the marking line, and the expanding material inside expands when the rainwater is wet, thereby improving the visibility of the road marking line and effectively reminding the driver.

[0022] An edge adhesive layer 10 is provided at both ends below the coating layer 11. A flexible strip 9 is provided on the inner side of the edge adhesive layer 10. A strip-shaped sealing film bag 7 is provided on the inner side of the flexible strip 9. An isolation layer 8 is provided on the surface of the flexible strip 9 and the strip-shaped sealing film bag 7. Pressure-sensitive adhesive is applied between the flexible strip 9 and the isolation layer 8. The adhesive force between the flexible strip 9 and the coating base layer 2 is greater than the adhesive force between the flexible strip 9 and the isolation layer 8. The function of the flexible strip 9 is to provide a certain support for the strip-shaped sealing film bag 7, which has no fixed shape, so that the strip-shaped sealing film bag 7 is located in a relatively fixed space formed by the flexible strip 9 and the isolation layer 8, so as to avoid the film being punctured and the adhesive leaking out during transportation and storage. The flexible strip 9 and the isolation layer 8 play a protective role.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
