Problems solved by technology

When a single metal ion-loaded inorganic antibacterial agent is added to the ink, the antibacterial effect is not significant, or the product changes color. For example, the antibacterial effect of the sample obtained by adding silver ion-loaded zeolite or silicon oxide antibacterial agent to the ink is reproducible. Bad or insignificant, and the wear of equipment such as three-roll machines is serious during the ink production process, so it is not suitable for ink production
[0004] Japanese patents JP10204353 and JP9039369 use an inorganic-organic composite antibacterial agent, but the defect of the patent is that the fineness of the composite antibacterial agent cannot be effectively controlled, which will obviously affect the printing suitability and storage stability of the ink, and then affect the actual Printing effect and shelf life of ink

Abstract

The invention relates to an antibiotic printing ink and its preparation method. The antibiotic printing ink comprises 5-20 wt% compound antimicrobial agents in the base material of the printing ink. The compound antimicrobial agent is a mixture of inorganic-organic compound antimicrobial agent and rosin modified phenolic resin. The inorganic-organic compound antimicrobial agent comprises inorganic antimicrobial agent and organic antimicrobial agent. The inorganic antimicrobial agent is phosphate or glassing micro powder loading silver ion, zinc ion, or silver-zinc compound ion. The inventive printing ink adopts compound antimicrobial agent, and endow the printing ink with bacteria resistance with broad spectrum, long term and high performance. The product is hard to discolor and cause no wear to the process equipment during preparing process. The inventive printing ink has no foreign odor, and no toxicity and irritation proven by rat acute toxicity test and acute rabbit skin stimulus test.

Description

technical field [0001] The invention relates to an ink, in particular to an antibacterial ink and a preparation method thereof. Background technique [0002] With the improvement of people's awareness of environmental protection and the rise of environmentally friendly printing, the printed materials that people come into contact with are non-toxic. However, such printed materials are more likely to breed bacteria and mildew when stored. Printed matter is contaminated with microorganisms, including many pathogenic bacteria, which can easily become the medium of transmission of germs and pose a potential threat to human health. Therefore, in addition to certain antibacterial treatment to the printing substrate (paper and plastic, etc.), certain antibacterial treatment is also required for the ink printed on the surface. [0003] Japanese patents JP9291243, JP9263725, JP8337078, and Chinese patent CN1195120C relate to antibacterial inks, and the above four patents generally u...
