High-transmittance anti-radiation optical glass and preparation method thereof

Abstract

The invention discloses high-transmittance anti-radiation optical glass and a preparation method thereof. The optical glass comprises an optical glass substrate, the surface of the optical glass substrate is coated with a surface functional layer, and a low-radiation layer is arranged between the optical glass substrate and the surface functional layer. The low-radiation layer is formed by sputtering zinc powder and titanium dioxide, the surface of the low-radiation layer is coated with mixed slurry to form a surface functional layer, and the high-transmittance anti-radiation optical glass is formed through high-temperature curing; wherein the mixed slurry is mainly prepared from 3, 4-ethylenedioxythiophene, nano silicon dioxide sol, persulfate, water, a surfactant and poly (p-styrenesulfonic acid). The transmittance of the optical glass prepared by the scheme reaches 94-95%, and the optical glass is good in radiation resistance, simple in preparation process and relatively high in practicability.
