Road reflective glass beads are small glass beads formed by melting glass sand (waste glass) at high temperatures. They are spherical, colorless, and transparent when viewed under a microscope, with a refractive index of 1.50-1.64, and a diameter generally between 75 microns and 1400 microns. They are also known as reflective glass beads. As a reflective material in road markings (paints), road reflective glass beads can improve the retroreflective performance of pavement markings and improve the safety of driving at night, and have been determined by transportation departments in various countries. When a car is traveling at night, the lights illuminate the road marking line with glass beads, which can cause the light from the lights to be reflected back in parallel, enabling the driver to clearly see the direction of travel and improving the safety of driving at night. Nowadays, reflective glass beads have become irreplaceable reflective materials in road safety products. Reflective glass beads for road use are mainly used in ambient temperature and hot-melt road marking coatings. One type of reflective glass beads is used as a premix material to ensure long-term reflection of the marking during its service life; The utility model relates to a surface spreading method during line marking construction, which can provide an instant reflective effect. There are two types of coated glass beads, one for highway reflection and the other for screen reflection. Coated glass beads utilize a high-performance organic material to externally treat glass beads, reducing the adsorption of dust in the air on the surface of the glass beads. Due to the specific coupling agent contained in the coated beads, the improved adhesion between the beads and the coating can prevent some small glass beads from depositing into the coating. Due to its functional floatability, it floats on the surface of the coating when used. It has the largest surface area and can increase the utilization rate by more than 30%. The performance of glass bead coating treatment is more superior. In a humid environment with frequent rain and fog
