Abstract
The invention relates to the field of preparation of new papermaking materials, in particular to a preparation method of a vanadium-doped antibacterial papermaking material; the invention discloses a preparation method of a vanadium-doped antibacterial papermaking material, which comprises the steps of adding straw, straws, bagasse, carboxymethyl cellulose and water into a beater, pulping and stirring the materials into slurry, heating the slurry to separate fibers in the slurry, adding thermoplastic starch and fermentation enzyme into a system, fermenting the slurry, condensing the slurry, dehydrating the slurry to form paste, adding the vanadium-doped antibacterial material and various auxiliary agents, uniformly stirring the slurry, coating, dehydrating, drying, pressing, cutting and packaging the slurry to obtain the vanadium-doped antibacterial papermaking material.
Description
Technical Field
The invention relates to the field of material preparation, in particular to a preparation method of a vanadium-doped antibacterial papermaking material.
Background
The paper material has wide application, and the body shadow can be seen everywhere from daily living goods, industrial production and material circulation. The paper and paperboard packaging material accounts for more than 50% of the whole packaging material. The antibacterial paper is functional paper with the capability of inhibiting bacteria, mould and paper pests. The development and development of antibacterial paper materials are also receiving widespread attention. .
CN105484102A provides a papermaking antibacterial agent, which is prepared from the following raw materials in parts by weight: 28g of dithiocyano-methane, 20g of dibenzoyl peroxide, 45g of sodium dodecyl sulfate, 100024.0 g of polyethylene glycol and 12g of formaldehyde, and the preparation method comprises the following steps: the antibacterial agent is prepared by mixing the raw materials and uniformly stirring, and has an excellent antibacterial effect and is convenient to use.
CN104894912A discloses a papermaking process, which is prepared from three major parts, namely main materials, papermaking auxiliary agents and papermaking mold, and comprises the following main materials in parts by weight: 10-30 parts of needle-leaved wood, 8-24 parts of reed, 5-15 parts of wheat straw, 10-26 parts of bagasse, 6-18 parts of cellucotton and 30-50 parts of starch, and the papermaking auxiliary agent comprises the following components in parts by weight: 3-8 parts of sizing agent, 4-6 parts of defoaming agent, 5-10 parts of whitening agent, 2-5 parts of antibacterial and antibacterial agent and 6-12 parts of filler water suspension, and the papermaking mold comprises the following components in parts by weight: 1-3 parts of white-rot fungi, 2-5 parts of xylanase and 3-6 parts of yeast; the paper making process has smooth paper surface, softness, brightness, excellent ink resistance, water resistance, corrosion resistance and other performance.
