A kind of high transmittance anti-radiation optical glass and its preparation method

Abstract

The invention discloses a high-transmittance and anti-radiation optical glass and a preparation method thereof. The optical glass includes 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-emissivity layer is formed by sputtering zinc powder and titanium dioxide, and the surface of the low-emissivity layer is coated with a mixed slurry to form a surface functional layer, which is cured at a high temperature to form a high-transmittance and anti-radiation optical glass; the mixed slurry is mainly composed of 3,4- Ethylenedioxythiophene, nano-silica sol, persulfate, water, surfactant, polystyrene sulfonic acid. The transmittance of the optical glass prepared by this scheme reaches 94-95%, the anti-radiation performance is good, the preparation process is simple, and it has high practicability.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a high-transmittance and anti-radiation optical glass and a preparation method thereof. Background technique [0002] Optical glass is made by mixing high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides according to a specific formula, melting in a platinum crucible at high temperature, and injection molding; optical glass has a high degree of Transparency, high chemical and physical uniformity, with specific and precise optical constants, are key materials for manufacturing lenses, prisms, mirrors, windows, optical fibers, etc. of optical instruments or mechanical systems; with electronic products With the rapid development of myopia, myopia tends to be younger and more popular; more and more people need to wear optical myopia lenses; strong sunlight stimulation will cause blurred vision, and there is a high safety hazard; in ad...
