preparation example Construction
[0016] The present invention also provides a preparation method of the automobile air-conditioning antibacterial filter, comprising the following steps:
[0017] (1) dissolving starch in water, then adjusting the pH of the system to 5.3-6.1 to obtain a starch solution, adding sodium phytate to the starch solution, and stirring for 2-5 hours to obtain starch-sodium phytate nanoparticles;
[0018] (2) Calcining diatomite at 300-500°C for 1-4h to obtain calcined diatomite, then mixing the calcined diatomite, silane coupling agent and starch-sodium phytate nanoparticles in water, and Stirring and reacting at 60-80°C for 0.5-3 hours to obtain modified starch-sodium phytate nanoparticles;
[0019] (3) Ultrasonically disperse graphene oxide in ethanol for 15 to 30 minutes to obtain a graphene suspension, adjust the pH of the system to 7.6 to 8.5, and then add 1-(3-dimethylaminopropyl)-3-ethyl carbon Diimine, N-hydroxysuccinimide and amoxicillin are stirred and reacted for 24-48 hour...
