Embodiment 1
[0037] Embodiment 1 (the following are all in parts by mass):
[0038]In a three-necked flask equipped with a stirrer, a thermometer, and a dropping funnel, add 30g of vinyltrimethoxysilane, 48g of ethyl orthosilicate, 22g of γ-methacryloxypropyltrimethoxysilane, 30g of TPGDA, 33g of Boric acid was heated to 70°C, kept at reflux and stirred for 4 hours, then stirred at vacuum for 1 hour, and left for 12 hours to obtain a sol. The sol is mixed with UV curable resin, active diluent, photoinitiator, leveling agent, etc. to prepare an organic-inorganic hybrid coating material. Among them, the flame-retardant and wear-resistant sol accounted for 30 wt%, and then added epoxy acrylate 17 wt%, pentaerythritol hexaacrylate 23 wt%, dipropylene glycol diacrylate 10 wt%, trimethylolpropane triacrylate 7 wt %, silicon dioxide nanopowder modified by vinyltriethoxysilane 5 wt %, titanium dioxide nanopowder modified by methylvinyldiethoxysilane 3 wt %, benzophenone 1 wt %, 2-hydroxy-2-methy...
Embodiment 2
[0040] In a three-necked flask equipped with a stirrer, a thermometer, and a dropping funnel, add 50 g of tetraethyl orthosilicate, 16 g of vinyl tris(2-methoxyethoxy) silane, 25 g of γ-methacryloxypropyl Trimethoxysilane, 42g ethyl titanate and 5g AlCl 3 Add to 20°C, complete the dropwise addition within 2 hours, then raise the temperature to 50°C, keep warm and reflux for 2 hours, raise the temperature to 90°C, keep warm and reflux and stir for 5 hours, then add 15g of HDDA and 15g of TMPTA respectively, and mix them uniformly at 55°C Distilled under reduced pressure for 3h to obtain the sol. The sol is mixed with UV curable resin, active diluent, photoinitiator, leveling agent, etc. to prepare an organic-inorganic hybrid coating material. Among them, the flame retardant and wear-resistant sol accounted for 50wt%, and then added polyurethane acrylate 11wt%, epoxy acrylate 8wt%, triethoxytrimethylolpropane triacrylate 13%wt, cyclocarbonate Monoacrylate 7 wt %, vinyltrimetho...
Embodiment 3
[0042] In a three-necked flask equipped with a stirrer, a thermometer, and a dropping funnel, pass N 2 Add 30g ethyl orthosilicate, 7g 3-trimethoxysilane propyl acrylate, 10g methylvinyldiethoxysilane, 23g propenyltrichlorosilane, 15g 3-chloropropyltrimethoxysilane, 27g ZrCl 4 , 30g TPGDA and 2g Ba(OH) 2 During stirring, the temperature was raised to 80° C., and the sol was obtained after reflux and stirring for 8 hours. The sol is mixed with UV curable resin, active diluent, photoinitiator, leveling agent, etc. to prepare an organic-inorganic hybrid coating material. Among them, the sol accounts for 45 wt%, epoxy acrylate 13 wt%, amino acrylate 7 wt%, neopentyl glycol diacrylate 10 wt%, trimethylolpropane triacrylate 5 wt%, pentaerythritol triacrylate 5 wt %, 3-trimethoxysilane propyl acrylate modified silica nanopowder 5 wt %, vinyltriethoxysilane modified zirconia nanopowder 3 wt %, diphenyl Methanone 2 wt %, 2-Dimethylamino-2-benzyl-1-[4-(4-morpholinyl)phenyl]-1-butanon...
