[0048] A preparation method for antibacterial filler special paper, comprising the following steps:
[0049] 1) Dissolving the organic ligand in an organic solvent to prepare an organic ligand solution, adding fillers to the organic ligand solution, and ultrasonically dispersing evenly to obtain a precursor solution;
[0050] 2) dissolving the metal center in an organic solvent and stirring until completely dissolved to obtain a metal ion solution;
[0051] 3) Add the metal ion solution in step 2) to the precursor solution in step 1), then transfer the mixed solution to the reaction vessel, and react by heating / pressurizing to combine metal ions and organic ligands Deposit on the filler by chemical deposition, then filter, wash with organic solvent several times and then dry to obtain the composite of filler and metal organic framework compound;
[0052] 4) The compound obtained in step 3) is added to the natural fiber and cationic polyacrylamide in the form of filling in the...
