Water-based environment-friendly ethylene oxide sterilization indicating ink and preparation method thereof

The invention relates to water-based environment-friendly ethylene oxide sterilization indicating ink and a preparation method thereof, and belongs to the technical field of medical sterilization. The water-based environment-friendly ethylene oxide sterilization indicating ink is prepared from the following raw materials in percentage by mass: 10 to 40 percent of binder, 0.1 to 1 percent of organic dye A, 0.1 to 1 percent of organic dye B, 5 to 10 percent of control agent and 30 to 80 percent of an alcohol aqueous solution. The water-based environment-friendly ethylene oxide sterilization indicating ink is a water-soluble system, has the advantages of being good in stability, low in VOCs emission, non-toxic, environmentally friendly and the like, can be visually interpreted when being applied to an indicator, and is high in accuracy, time-saving, efficient and wide in application field; the invention also provides a simple and feasible preparation method. 本发明涉及一种水基环保环氧乙烷灭菌指示油墨及其制备方法，属于医疗灭菌技术领域。本发明所述的水基环保环氧乙烷灭
