Embodiment 1
[0026] At room temperature, dissolve 2g of cetyltrimethylammonium chloride in 960g of deionized water, add 6ml of 2mol / L NaOH solution, and stir evenly. Raise the temperature to 80°C, add 4g of SnCl with a mass percentage of 40% 4 ·5H 2 O aqueous solution, stirred for 15min, then added dropwise 10mL tetraethyl orthosilicate, stirred vigorously, and reacted at 80°C for 2h. The above-mentioned glue solution was transferred to a polytetrafluoroethylene-lined stainless steel hydrothermal kettle and sealed and matured at 105°C for 24 hours. After repeated washing and filtration, a white powder was obtained, and vacuum-dried. Then place it in a tube furnace and calcinate at a heating rate of 3°C / min to 550°C for 6h to obtain a tin-doped mesoporous silica smoke suppressant.
Embodiment 2
[0028] At room temperature, dissolve 1.96g of dodecyltrimethylammonium bromide in 800g of deionized water, add 12ml of 1mol / L NaOH solution, and stir evenly. Heat up to 70°C, add 8g of SnCl with a mass percentage of 40% 4 ·5H 2 The aqueous solution of O was stirred for 15 min, then 8.4 mL of methyl orthosilicate was added dropwise, stirred vigorously, and reacted at 70°C for 2 h. The above-mentioned glue solution was transferred to a polytetrafluoroethylene-lined stainless steel hydrothermal kettle and sealed and matured at 105°C for 24 hours. After repeated washing and filtration, a white powder was obtained, and vacuum-dried. Then place it in a tube furnace and calcinate at a heating rate of 3°C / min to 550°C for 6h to obtain a tin-doped mesoporous silica smoke suppressant.
Embodiment 3
[0030] At room temperature, dissolve 1.68g of tetradecyltrimethylammonium bromide in 748g of deionized water, add 5ml of 3mol / L NaOH solution, and stir evenly. Heat up to 80°C, add 2g of SnCl with a mass percentage of 40% 4 ·5H 2 O aqueous solution, stirred for 15min, then added dropwise 10mL tetraethyl orthosilicate, stirred vigorously, and reacted at 80°C for 2h. The above-mentioned glue solution was transferred to a polytetrafluoroethylene-lined stainless steel hydrothermal kettle and sealed and matured at 105°C for 24 hours. After repeated washing and filtration, a white powder was obtained, and vacuum-dried. Then place it in a tube furnace and calcinate at a heating rate of 3°C / min to 550°C for 6h to obtain a tin-doped mesoporous silica smoke suppressant.
