The invention discloses a method for preparing antibacterial tipping paper, which comprises the following steps: preparing an aqueous solution containing glucose, peptone, yeast powder and citric acid monohydrate; after sterilization, inoculating activated Acetobacter gluconate ZT-01; culturing to obtain a bacterial cellulose membrane; swelling the bacterial cellulose membrane and washing to neutrality; beating the bacterial cellulose membrane; adding ε-polylysine, glycine and a cross-linking agent to the bacterial cellulose pulp, shaking The antibacterial composite material is obtained by the reaction; the antibacterial composite material is mixed into the pulp for papermaking, and the antibacterial tipping paper is prepared. In the preparation method of the antibacterial tipping paper of the present disclosure, the combined action of ε-polylysine and an appropriate amount of glycine can significantly improve the bacteriostatic properties of ε-polylysine. Bacterial cellulose has bioaffinity and biocompatibility, and has a huge specific surface area and a large number of hydroxyl groups, which can firmly bind bacteriostatic agents by reacting with amino groups. In addition, bacterial cellulose can enhance the strength and toughness of tipping paper. |
