Description

Technical Field

[0002] Glass beads are a new type of material with a wide range of uses and special properties developed in recent years. This product has the advantages of light weight, low thermal conductivity, high strength, and good chemical stability. Glass beads are the most commonly used night reflective material in road marking paints for urban roads. The application of reflective glass beads in road markings is achieved through retroreflective technology: when driving at night, the lights of vehicles shine on the road markings, and the reflective glass beads contained in the paint produce a retroreflective effect on the car lights. The driver can see the markings clearly and judge the driving route, effectively avoiding traffic accidents.

[0003] A reflective glass bead for highway with publication number CN211522956U comprises a bead body, a reflective glitter sheet and a transparent varnish, wherein the reflective glitter sheet is scattered in the bead body, the surface of the bead body is coated with transparent varnish, the reflective glitter sheet is evenly kneaded in the bead body, the reflective glitter sheet is a reflective aluminum-plated sheet, and glass microbeads are a new type of material with a wide range of uses and special performance developed in recent years. In the utility model, the reflective glass beads will enter the bead body through refraction under the illumination of a light source, and will be reflected multiple times by the reflective glitter sheet in the bead body to form a shining point, so that the reflective glass beads emit a bright light under the illumination of street lamps, increase the visibility range at night, remind drivers of the edge of the road, and prevent drivers from hitting the curb, but reflective markings are usually used outdoors and exposed to the air. After a long period of wind and sun, the glass beads are easy to fall off, thereby affecting the reflective effect. Utility Model Content
