Preparation method of antibacterial porous ceramic capable of adsorbing formaldehyde
The invention relates to a preparation method of antibacterial porous ceramic capable of adsorbing formaldehyde. The preparation method comprises the following steps: (1) preparing hydroxyl silver-loaded apatite powder; (2) preparing the porous antibacterial ceramic; (3) preparing the antibacterial porous ceramic for adsorbing formaldehyde; the ceramic material is prepared by adopting a step-by-step synthesis and anchoring method, firstly, hydroxyl silver-loaded apatite is synthesized by adopting a hydrothermal method, then the hydroxyl silver-loaded apatite is compounded with a ceramic raw material, and antibacterial porous ceramic is prepared by adopting a normal-pressure sintering method. MOFs (MIL-101) are synthesized through a hydrothermal method, finally, the MOFs (MIL-101) are anchored to the porous ceramic through a binding agent, finally, the antibacterial formaldehyde adsorption porous ceramic is prepared, the formaldehyde adsorption function and the sterilization function cannot be reduced, the formaldehyde adsorption function and the sterilization function are doubly superposed, the performance is stable, the dual functions of resisting bacteria and adsorbing formaldehyde are achieved, and the antibacterial formaldehyde adsorption porous ceramic is suitable for being used for preparing antibacterial formaldehyde adsorption porous ceramics. When the antibacterial porous ceramic product for adsorbing formaldehyde is used for adsorbing formaldehyde, the formaldehyde adsorption capacity can reach 80 mg/g or above, and the antibacterial rate can reach 98% or above.
