Directional reflective ceramic wafer

Abstract

The invention provides a directional reflective ceramic wafer. The ceramic wafer comprises a ceramic wafer body, wherein slopes are arranged on the periphery of the top surface of the ceramic wafer body; uniformly distributed silver-aluminium-plated glass microspheres (which are transparent and have high refractive index) are connected with the slopes of a pair of sides of the top surface of the ceramic wafer body via adhesive layers; and the thickness of the ceramic wafer body is 7.5-12-15mm. The ceramic wafer has the following advantages: the glass microspheres are adhered to the ceramic wafer body through the adhesive layers and cannot fall off easily; the elevation structure of the ceramic wafer can well reflect light in rainy days; reflectors in right angle concave holes still can have good reflecting effects when other reflective layers cannot reflect light; the ceramic wafer is 6mm higher than a road surface and the height is reduced, thus reducing jolt and the destruction ratio; inclined plane on the periphery form slopes, thus preventing the raised ceramic road signs from being shoved during snow shovelling and prolonging the life of the ceramic wafer; drivers can see a light band formed by reflective spots 100-200m away in rainy and foggy nights by virtue of the high-strength silver-aluminium plated glass microspheres and cat eyes; and heat absorbed by a wall surface can be reduced when the directional reflective ceramic wafer is used as external tile.

Description

technical field [0001] The invention relates to road traffic signs and markings, in particular to a directional reflective ceramic sheet, which is used for bonding on the road surface to form road signs and markings, and can also be used for directional reflection on the wall to reduce the temperature of the wall surface and inside the wall. Energy saving and environmental protection. Background technique [0002] The current road markings mainly use hot-melt reflective coatings, cold-spray solvent-based coatings, preformed plastic marking tapes, raised road markings, ceramic markings, etc. These markings rely on glass beads to reflect light, and the glass beads lose their reflective effect after being covered by water, which especially affects the operation of highway vehicles. The traditional organic glue as the main material is easy to stick to pollutants and turn black, and the self-cleaning force is too low. In some areas, the line will be dirty and invalid after three...

Problems solved by technology

[0013] One of the objectives of the present invention is to provide a directional reflective ceramic sheet and a combination of reflective road signs and wall reflective signs to solve the problem of poor reflection of expressway markings at night in wind, rain and fog, pollution of markings becoming black, not durable, high Inappropriate, the reflective material is not firmly pasted and is easy to be rubbed off by the wheels, and prevents the problem of damaging the raised road signs when plowing snow on the road; the second purpose of the present invention is to provide a wall reflective sign composed of directional reflective ceramic sheets , using its directional reflection characteristics as exterior wall bricks to reduce the heat absorption of the wall
