Embodiment 1
[0078] (1) Preparation of light-shielding black paste
[0079] Add 63 parts by mass of butanone, and add 0.06 parts by mass of polyether-modified polydimethylsiloxane interpolymer (BYK-333) and isopropyl tris(dodecylbenzenesulfonyl) titanate under stirring 0.29 parts by mass, stirred at 300rpm for 30min, slowly added 10 parts by mass of carbon black powder under stirring, stirred at 500rpm for 180min, monitored the particle size of the slurry, and the particle size was required to be <5μm. Then add 10.65 parts by mass of carboxyl-terminated nitrile rubber (1072CGJ), 16 parts by mass of aluminum hydroxide powder, and stir at 500 rpm for 120 min. Choose zirconium beads of φ1.5-φ1.6mm, sand mill for 24 hours, monitor the particle size of the slurry, the particle size is required to be <10um, the particle size distribution is uniform, the appearance is smooth after coating, and there are no obvious particles. Then seal it with a PE bag and store it at a low temperature of 5-10°C....

[0086] (1) Preparation of light-shielding black paste
[0087] Add 63 parts by mass of butanone, and add 0.07 parts by mass of polyether-modified polydimethylsiloxane (BYK-306) and isopropyl dioleic acid acyloxy (dioctyl phosphate acyloxy) under stirring 0.30 parts by mass of titanate, stirred at 300 rpm for 30 minutes, slowly added 9 parts by mass of carbon black powder under stirring, stirred at 500 rpm for 180 minutes, monitored the particle size of the slurry, the particle size requirement was The zirconium beads should be sanded for 24 hours, and the particle size of the slurry should be monitored. The particle size should be less than 10 μm, the particle size distribution should be uniform, and the appearance should be smooth after coating without obvious particles. Then seal it with a PE bag and store it at a low temperature of 5-10°C.
