Abstract

The invention discloses a preparation process for medical antibacterial packing paper. The preparation process comprises the following steps: adding water to polylactic acid fibers to prepare a solution, adding a certain amount of konjac glucomannan for modification, and performing microwave treatment; adding water to chitosan fibers, heating, adding sodium alginate for modification, and performing ultrasonic treatment; treating polyester pulp by virtue of low-temperature plasmas, and performing dispersion and jordaning; performing blending with wood pulp, adding certain amounts of polylactic acid fibers, chitosan fibers, polyester modified pulp, cationic guar gum, cationic polyacrylamide and silica sol, and forming a wet paper web in a sheet former; adding a certain amount of polyvinylpyrrolidone for surface enhancement, and performing oil pressure treatment and drying to obtain the medical antibacterial packing paper. According to the preparation process, the requirement of disinfecting and sterilizing a packed product through the paper can be met, invasion of external bacteria can also be shielded, and various main technical indexes reach the quality levels of medical antibacterial packing paper.

Description

technical field [0001] The invention belongs to the field of special paper, and in particular relates to a preparation process of medical antibacterial packaging paper. Background technique [0002] Medical antibacterial packaging paper is a kind of packaging paper with bacterial barrier requirements, which can not only meet the requirements of penetrating paper for disinfection and sterilization of packaged products, but also block the invasion of external bacteria and play the role of antibacterial; at the same time The paper is required to be smooth, high tensile strength, suitable for printing and post-processing requirements, and it is a special paper with high added value. [0003] Therefore, the development of medical antibacterial packaging paper with good antibacterial properties, high strength and good smoothness can be used in medical auxiliary materials, food packaging materials and other fields, which can meet the safety and hygiene requirements of medical packa...
