Road glass rock is mainly used in normal temperature and hot-melt road marking paints. There are two types of premixed and surface sprayed. The premixed glass rock can be mixed in the paint during the production of hot-melt road coatings, which can ensure long-term reflection of road markings during the life of the road. The other type can be sprinkled on the surface of the road marking to have an instant reflective effect. The surface-treated coated glass rock can be used in the construction of road markings, which can greatly improve the adhesion between glass rock and hot-melt markings, enhance the refractive index of road markings, and have self-cleaning, anti-fouling, moisture-proof, etc. . Road glass stone is used to improve the reverse performance of road coatings and improve the safety of drivers driving at night.
