Embodiment 1
[0031] Step 1, in parts by weight, mix 15 parts of tetrabutyl titanate, 2 parts of sodium sulfate, and 200 parts of water, stir at 10°C for 0.5h, then raise the temperature to 75°C, and add sulfuric acid with a mass concentration of 5% dropwise solution to keep the pH of the reaction solution at 9, after the dropwise addition, naturally cool to room temperature, age for 0.5h, then add dropwise a sulfuric acid solution with a mass concentration of 5% to make the pH of the reaction solution at 3, add 15 parts of hydroxy silicone oil, and stir After 1h, age for 3h, filter, and wash the filter cake with water until there is no SO 4 2- , obtained amino silicone oil modified titanium oxide powder after vacuum drying;
[0032] Step 2, by weight, 0.5 parts of dispersant sodium tripolyphosphate, 1 part of N-vinylpyrrolidone, 20 parts of methyl methacrylate, 2 parts of crosslinking agent butanediamine, and 50 parts of organic solvent butanol Mix evenly, then slowly add 12 parts of ami...
Embodiment 2
[0035]Step 1, in parts by weight, mix 20 parts of tetrabutyl titanate, 5 parts of sodium sulfate, and 260 parts of water, stir at 20°C for 3 hours, then raise the temperature to 85°C, and add dropwise a sulfuric acid solution with a mass concentration of 9%. Keep the pH of the reaction solution at 12. After the dropwise addition, cool naturally to room temperature, age for 2 hours, then add dropwise a sulfuric acid solution with a mass concentration of 9% to make the pH of the reaction solution at 5, add 20 parts of hydroxy silicone oil, and stir for 2 hours , aged for 5h, filtered, and the filter cake was washed with water until no SO 4 2- , obtained amino silicone oil modified titanium oxide powder after vacuum drying;
[0036] Step 2, by weight, 2 parts of dispersant sodium tripolyphosphate, 3 parts of N-vinylpyrrolidone, 28 parts of methyl methacrylate, 4 parts of crosslinking agent butanediamine, 65 parts of organic solvent butanol Mix evenly, then slowly add 15 parts o...
Embodiment 3
[0039] Step 1, in parts by weight, mix 18 parts of tetrabutyl titanate, 3 parts of sodium sulfate, and 220 parts of water, stir at 15°C for 0.2h, then raise the temperature to 80°C, and add sulfuric acid with a mass concentration of 8% dropwise solution to keep the pH of the reaction solution at 11, after the dropwise addition, naturally cool to room temperature, age for 1h, then add dropwise a sulfuric acid solution with a mass concentration of 6% to make the pH of the reaction solution at 4, add 16 parts of hydroxy silicone oil, and stir for 2h After aging for 4h, filtered, the filter cake was washed with water until no SO 4 2- , obtained amino silicone oil modified titanium oxide powder after vacuum drying;
