The reflective glass bead of road marking coating is a glass solid sphere with small diameter after crushing the glass containing silicon, sodium, calcium and other components and firing at high temperature, which has good reflective performance. It is applied to normal temperature and hot-melt ordinary marking coatings as premixed material to achieve reflective effect.
道路标线涂料的反光玻璃珠是由含硅、钠、钙等成分的玻璃粉碎后，经过高温烧制而成直径微小的玻璃实心球体，具有较好的反光性能。将其应用在常温型、热熔普通型标线涂料中，作为预混材料面撒，起到反光效果。
