Pressure steam sterilization water-based organic ink as well as preparation method and application thereof

Abstract

The invention provides pressure steam sterilization water-based organic ink as well as a preparation method and application thereof. The pressure steam sterilization water-based organic ink is prepared from the following raw materials: 15wt%-50wt% of a binder, 0.1 wt%-2 wt% of an organic dye, 2 wt%-20 wt% of an alkaline control agent, and 30 wt%-80 wt% of an aqueous system solvent, wherein the aqueous system solvent is composed of water and an organic solvent; and the organic solvent is selected from one or more of methanol, ethanol, n-propanol, isopropanol and n-butanol. Compared with the prior art, the pressure steam sterilization water-based organic ink provided by the invention adopts the water-based system solvent and is matched with other components with specific content to realize better interaction, the color of the product can be changed after pressure steam sterilization so as to play an indication role. In addition, the pressure steam sterilization water-based organic ink has the advantages of low VOCs emission, no heavy metal, and ability of avoiding heavy metal pollution, and can be widely applied to printing of products such as indicator cards, indicator labels (adhesive tapes) and paper-plastic bags.

Description

Technical field [0001] The present invention relates to the field of ink, and more particularly, to a pressure steam sterilization water-based organic ink and a preparation method thereof. Background technique [0002] In the daily work of hospitals, there are often various instruments, which are used to disinfect and sterilize. With the continuous improvement of health understanding, more and more demand for various medical supplies, these products need to be strictly sterilized before use, and the sterilization process also involves medical, pharmaceutical, food, and hygiene. Many fields such as supplies. Therefore, a higher requirement for routine testing and rapid identification of sterilization effects. [0003] Pressure Steam Sterilization is a sterilization of high temperature and high humidity instruments used in hospitals. According to the national standard for medical devices, the hospital medical staff must be sterilized for the instrument of the instrument, and the co...
