Embodiment 1
[0035] (1) Preparation of mixed solution: at room temperature, 0.5g methyl methacrylate, 2g acrylic acid, 0.02g azobisisobutyronitrile, 1g nano-SiO 2 Dissolve in 40g of acetone, and mix uniformly to obtain a mixed solution.
[0036] (2) The mixed solution and the plexiglass substrate are sprayed and mixed: 15g of the plexiglass substrate is put into a high-speed mixer, and the mixed solution prepared in (1) is sprayed on the plexiglass substrate at intervals, spraying once every 5 minutes, every Spray for 30 seconds for the first time, and then mix for another 30 minutes after all the mixed solution is sprayed to ensure that the mixed solution is evenly mixed with the plexiglass substrate, and plexiglass A is finally obtained.
[0037] (3) Dry the plexiglass to remove the solvent: Dry the plexiglass A prepared in (2) with an electric blast drying oven to remove the organic solvent. The drying temperature is 80° C. and the drying time is 4 hours to obtain the plexiglass B. . ...
Embodiment 2
[0043] (1) Preparation of mixed solution: at room temperature, 1g methyl methacrylate, 1.2g KH570, 0.04g azobisisobutyronitrile, 2g nano-SiO 2 Dissolve in 80g of acetone, and mix uniformly to obtain a mixed solution.
[0044] (2) The mixed solution and the plexiglass substrate are sprayed and mixed: 30g of the plexiglass substrate is put into a high-speed mixer, and the mixed solution prepared in (1) is sprayed on the plexiglass substrate at intervals, spraying once every 5min, every Spray for 30 seconds for the first time, and then mix for another 30 minutes after all the mixed solution is sprayed to ensure that the mixed solution is evenly mixed with the plexiglass substrate, and plexiglass A is finally obtained.
[0045] (3) Dry the plexiglass to remove the solvent: Dry the plexiglass A prepared in (2) with an electric blast drying oven to remove the organic solvent. The drying temperature is 80° C. and the drying time is 5 hours to obtain the plexiglass B. .

Embodiment 3
[0051] (1) Preparation of mixed solution: at room temperature, 1.5g methyl methacrylate, 6g maleic anhydride, 0.06g azobisisobutyronitrile, 3g nano-SiO 2 Dissolve in 160g of acetone, and mix uniformly to obtain a mixed solution.
[0052] (2) The mixed solution and the plexiglass substrate are sprayed and mixed: 45g of the plexiglass substrate is put into a high-speed mixer, and the mixed solution prepared in (1) is sprayed on the plexiglass substrate at intervals, spraying once every 5 minutes, every Spray for 30 seconds for the first time, and then mix for another 30 minutes after all the mixed solution is sprayed to ensure that the mixed solution is evenly mixed with the plexiglass substrate, and plexiglass A is finally obtained.
[0053] (3) Dry the organic glass to remove the solvent: Dry the organic glass A prepared in (2) with an electric blast drying oven to remove the organic solvent at a drying temperature of 80° C. to obtain the organic glass B.
