Volume scattering dodging sheet and preparation method thereof

The invention discloses a volume scattering dodging sheet, which is prepared by exposure of substrate glass, the substrate glass comprises the following components by weight: 8-14% of SiO2, 16-21% of B2O3, 55-62% of ZnO, 2-11% of Al2O3, 2-7% of ZrF4, and 0.3-2% of Ag2CO3, and the preparation process comprises the following steps: preparing the components into a mixture according to the weight ratio, putting the mixture into a ball mill, and grinding and mixing uniformly; transferring the mixture into a crucible for melting, wherein the melting temperature is 1350-1420 DEG C; at 1200-1300 DEG C, pouring molten glass into an aluminum bronze mold for forming, and quickly transferring into an annealing furnace for annealing; and finally, screening the annealed glass, selecting a stripe-free part, and cutting, grinding and polishing the stripe-free part to form substrate glass for preparing the volume scattering dodging sheet. The invention also provides a method for preparing the volume scattering dodging sheet a
