Abstract

The invention relates to a hydrogen peroxide plasma sterilization discoloration ink and a preparation method thereof, which belong to the technical field of medical supplies sterilization detection, and comprise a discoloration ink and a common pigment, wherein the discoloration ink comprises methyl blue 0.8-1.2g, methyl violet 6-10g, absolute alcohol 6500-7500ml, ethyl acetate 800-1200ml, triethanolamine 45-55ml, butyl acetate 800-1200ml and poly urethane (PU) resin adhesive 2.8-3.2kg, and the common pigment comprises phenosafranine 0.1-0.3g and absolute alcohol 45-55ml. The method for preparing the hydrogen peroxide plasma sterilization discoloration ink comprises steps: the methyl blue and the methyl violet are added into the absolute alcohol, are added with the ethyl acetate, the butyl acetate and the triethanolamine after being stirred and dissolved, then a dissolved solution is filtered, and is added with the PU resin adhesive to prepare a discoloration pigment, the phenosafranine is added into the absolute alcohol to prepare a common pigment by being stirred and dissolved, and the prepared common pigment is added into the discoloration pigment at last, and is uniformly stirred to prepare the hydrogen peroxide plasma sterilization discoloration ink. The hydrogen peroxide plasma sterilization discoloration ink which is prepared through the method for preparing the hydrogen peroxide plasma sterilization discoloration ink is high in sensitivity, strong in stability and thorough in color change, can rapidly detect sterilizing effect, and is short in use time and high in accuracy rate.

Description

technical field [0001] The invention relates to a color-changing ink and a preparation method thereof, in particular to a hydrogen peroxide plasma sterilized color-changing ink and a preparation method thereof, belonging to the technical field of medical product detection. Background technique [0002] With the rapid development of China's economy, the improvement of people's living standards and awareness of health, there is an increasing demand for various medical equipment and supplies, which require strict sterilization before use , the commonly used sterilization method is high temperature sterilization. With the rapid development of medical and health services and the continuous improvement of medical technology, various precision instruments and equipment are gradually popularized and applied, and these equipment generally cannot be sterilized by high temperature. [0003] In order to solve this problem, various low-temperature sterilization methods have emerged, the...
