Embodiment 1
[0018] 8mL butyl titanate (Ti(OBu) 4 ) was added dropwise into 20mL of ethanol with stirring at 50°C and mixed evenly, then 2mL of glacial acetic acid was added to obtain solution A. Then 60 mL of ethanol and 2 mL of distilled water were added with nitric acid under stirring to adjust the pH value to 1-2 to obtain solution B. Add solution B dropwise to solution A at a rate of 50-60 drops per minute, then add nitric acid to 60 mL of ethanol and 2 mL of distilled water under stirring to adjust the pH value to 2-3 to obtain solution B. Add solution B dropwise to solution A at a rate of 50-60 drops per minute, stir and adjust the pH value to 2-3, place it in a microwave oven with a power of 500-900W and heat it for 20-90s to obtain light yellow Transparent titanium sol.
Embodiment 2
[0020] Add 0.3mol / L copper nitrate and zinc nitrate solution dropwise to the sol, and the amount of ions added is 8:100 (the molar ratio of the total number of ions to butyl titanate), that is, 1.5g ions / 100mL butyl titanate, zinc and copper ions The molar ratio of the mixture is 2:1, stirred at 30°C for 2h, and then heated by microwave for 20-50s to obtain a titanium gel adsorbing zinc and copper ions. Then place the prepared gel in a drying oven to dry to obtain a loose xerogel. After grinding, place it in a crucible and put it in a furnace for calcination at 450°C and keep it warm for 30-60 minutes. After taking it out, you can get the desired antibacterial agent.
