Abstract

The invention relates to antibacterial and bacteriostatic aqueous ink, which contains 0.0005 to 6 weight percent of plant volatile oil. The antibacterial and bacteriostatic aqueous ink is provided by adding the antibacterial and bacteriostatic plant volatile oil into aqueous ink and performing adaptive improvement on the formula of the aqueous ink. The aqueous ink is particularly suitable for printing products with environmentally-friendly requirements such as packing presswork (such as cosmetics, paper towels, clothes, books and magazines, instruction books and the like) contacted with the human body, presswork of foodstuff (such as food, wine, cigarettes, health-care products and the like) packages, packing presswork contacted with medicaments, presswork of adhesive labels and the like.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to an antibacterial and antibacterial water-based ink. Background technique [0002] In daily life, people use a lot of printed products, such as food bags, food containers, sanitary napkins, napkins, food display paper, underwear packaging bags, medicine bags, medicine containers, etc.; they also come into contact with newspapers, magazines, printed books, etc. in large quantities. Most of these items that may be in direct contact with the human body are printed with patterns, advertisements or text. [0003] The development trend of ink is from solvent-based and oil-based systems to water-based or solvent-free systems. The main components of water-based inks are water-soluble resins, pigments (dyes), co-solvents and some additives added for production purposes or for specific functions of applications. In water-based inks, water accounts for 20%-40% by weight and thus constitutes a ...
