Abstract

The invention relates to antireflective organic glass and a preparation method thereof. The method comprises the following steps: (1) using a volatile organic solvent to evenly mix a small amount of polymeric monomer, initiator and functional monomer and a certain amount of SiO2 to prepare a mixed solution; (2) spraying the mixed solution for high-speed mixing with an organic glass substrate to obtain organic glass A; (3) drying the organic glass A prepared the step (2) to remove the solvent to obtain organic glass B; (4) treating the organic glass B prepared the step (3) by mixing to obtain a high concentration pre dispersed masterbatch; and (5) mixing the high concentration pre dispersed masterbatch with the organic glass substrate to obtain the antireflective organic glass. The preparation process is simple, economical and reliable, and the prepared antireflective organic glass has better ultraviolet transmittance, and can be widely used in the manufacture of transparent reagent kits.

Description

technical field [0001] The invention belongs to the field of processing and modification of light-transmitting materials, and specifically relates to an anti-reflection organic glass and a preparation method thereof.
