Abstract

The invention provides peroxide-sterilization water-based organic ink as well as a preparation method and application thereof. The peroxide-sterilization water-based organic ink is prepared from the following raw materials: 10wt%-45wt% of a binder; 0.1 wt%-2wt% of an organic dye; 1 wt%-20 wt% of an alkaline control agent; 50 wt%-75 wt% of an water-based system solvent; wherein the water-based system solvent consists of water and an organic solvent; the organic solvent is selected from one or more of methanol, ethanol, n-propyl alcohol, isopropanol and n-butyl alcohol. Compared with the prior art, the peroxide-sterilization water-based organic ink provided by the invention adopts the water-based system solvent; by matching with other specific content components, good interaction is realized, the color of the product changes after peroxide sterilization, so that an indication effect is achieved, and the ink has the advantages of low VOCs emission, no heavy metal and avoidance of heavy metal pollution, and can be widely applied to printing of products such as indication cards, indication labels (adhesive tapes), paper-plastic bags and the like.

Description

technical field [0001] The invention relates to the technical field of printing inks, and more specifically relates to a peroxide sterilized water-based organic printing ink and a preparation method and application thereof. Background technique [0002] In the daily work of the hospital, there are often various instruments and utensils that need to be disinfected and sterilized. With the continuous improvement of people's awareness of health, the demand for various medical supplies is increasing. These products need to be strictly sterilized before use. The sterilization process also involves medical treatment, medicine, food, hygiene Supplies and many other fields. Therefore, higher requirements are put forward for the routine inspection and rapid identification of the sterilization effect. [0003] Peroxide sterilization is a method of sterilizing instruments that are not resistant to high temperature and high humidity used in hospitals. According to the national regula...
