Abstract

The invention relates to the field of preparation of new papermaking materials, in particular to a method for preparing a vanadium-doped antibacterial papermaking material; the method of the invention discloses a method for preparing a vanadium-doped antibacterial papermaking material, which comprises straw, straw, bagasse , carboxymethyl cellulose and water are added to the beater to be beaten and stirred to form a slurry, and then heated to separate the fibers in the slurry, and then thermoplastic starch and fermentation enzymes are added to the system, and after fermentation, they are condensed and dehydrated to form a paste. Then add vanadium-doped antibacterial materials and various additives, stir evenly, coat, dehydrate and dry, press, cut, and package to obtain the vanadium-doped antibacterial papermaking material.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a preparation method of a vanadium-doped antibacterial papermaking material. Background technique [0002] Paper materials are widely used, from daily necessities to industrial production and material circulation, they can be seen everywhere. Paper and cardboard packaging materials account for more than 50% of the total packaging materials. Antibacterial paper is a functional paper with the ability to inhibit bacteria, mold and paper pests. The development and development of antibacterial paper materials have also received widespread attention. . [0003] CN105484102A provides a papermaking antibacterial agent, which is made of the following raw materials in parts by weight: 28 g of dithiocyanomethane, 20 g of dibenzoyl peroxide, 45 g of sodium dodecylsulfonate, 24.0 g of polyethylene glycol 1000, 12g of formaldehyde. The preparation method comprises the following steps: f...
