Abstract

The invention relates to antibacterial paper and a preparation method thereof. The antibacterial paper is bamboo fiber or wood fiber paper. Pulp of the bamboo fiber or wood fiber paper comprises an antibacterial compound accounting for 0.001-0.05wt% of bamboo fibers or wood fibers, and the antibacterial compound comprises silver-doped nano zinc oxide, nano titanium dioxide and dried lavender flowers. The preparation method includes adding the antibacterial compound into starch paste, and stirring evenly to obtain the evenly pasty antibacterial compound, wherein the mass ratio of the starch paste to the antibacterial compound is 100-200:1; adding the evenly pasty antibacterial compound into a sizing agent in the paper production process, stirring the sizing agent evenly, and forming and drying paper according to normal paper production to obtain the antibacterial paper. The antibacterial paper has the advantages that the antibacterial compound has good price advantages and high functionality, antibacterial ability is enhanced, and types of inhibited bacteria are plenty; effectiveness time of the antibacterial compound is prolonged effectively through addition of inorganic antibacterial materials, paper products have herbal fragrance due to addition of lavender, and the effects of relieving nervous emotion and calming mind are achieved.

Description

technical field [0001] The invention relates to a method for preparing paper products, in particular to antibacterial paper and its preparation method. Background technique [0002] Paper is one of the most commonly used daily necessities in people's lives, including toilet paper, facial tissue, napkins, food wrapping paper, etc., which are in direct or indirect frequent contact with human skin and organs. In recent years, due to the fluorescent powder whitening agents, dioxin carcinogens, bleaching agents, various germs, etc. contained in household paper, it has brought great harm to people's life and health. With antibacterial function. Especially for people with sensitive skin or sensitive parts of the human body, improper use of paper can cause skin redness, itching, and even inflammation, which brings unnecessary trouble and influence to people's normal life. As an ancient bacteriostatic material, silver has high-efficiency bactericidal effect, but as a precious metal...
