| titleOfInvention | High-refraction glass bead and preparation method thereof |
| abstract | The invention provides a high-refraction glass bead and a preparation method thereof, wherein the high-refraction glass bead comprises 28.3% of barium oxide, 8.9% of calcium oxide, 8% of zirconium oxide, 4.5% of zinc oxide, 3.5% of boric acid, 2.5% of aluminum oxide and the balance of a glass bead stabilizing additive, wherein the glass bead stabilizing additive is a high-refraction glass bead prepared by mixing aluminum stearate and/or zinc stearate, ball-milling, crushing, separating, balling and the like; the balling is carried out by adopting a pure oxygen and gas balling mode, and crushed glass powder is rapidly cooled after being pelletized through a pure oxygen and gas flame burner; the reflective road sign has stronger reflective light performance, can greatly improve the reflective effect thereof when being used as a road sign, and improves the driving safety of the automobile on the road at rainy night. |
