Description

technical field

[0001] The invention relates to a color-changing ink, in particular to a screen-printed ethylene oxide sterilized color-changing ink; the invention also relates to a preparation method of the screen-printed ethylene oxide sterilized color-changing ink. Background technique

[0002] At present, the domestic methods of sterilization of medical device packaging products mainly include: ETO ethylene oxide, STEAM high temperature and high pressure steam sterilization, gamma cobalt 60 ray irradiation, plasma, etc. ETO ethylene oxide is a broad-spectrum sterilant that can kill various microorganisms at room temperature, including spores, Mycobacterium tuberculosis, bacteria, germs, and fungi, and EO does not corrode plastics, metals, and rubber, and will not make objects Yellowing and brittleness occur. However, there are disadvantages such as no discoloration, long sterilization time, poor stability, incomplete discoloration, and insufficient color, which affect t...

Examples

Embodiment 1

[0029] a Take 5 parts of formaldehyde red, 100 parts of ethylene emulsion, 60 parts of alcohol with a concentration of 45%-60%, 6 parts of citric acid, and 8 parts of sodium chloride, and mix to obtain a mixture;

[0030] b. Heating the mixture in step a to 50° C. to obtain the screen printing ethylene oxide sterilized color-changing ink of the present invention.

Embodiment 2

[0032] a Mix 6 parts of formaldehyde red, 200 parts of ethylene emulsion, 70 parts of alcohol with a concentration of 45%-60%, 10 parts of citric acid, and 12 parts of sodium chloride to obtain a mixture;

[0033] b. Heat the mixture in step a to 55° C. to obtain the screen printing ethylene oxide sterilized color-changing ink of the present invention.

[0034] When using the present invention, apply it on the ethylene oxide sterilization indicator card, put the sterilized product into the sterilizer for sterilization, and put the ethylene oxide sterilization indicator card into the sterilizer, After the concentration of ethylene oxide is 600±50ml / 1, the temperature of the sterilizer is 50°C, the humidity is 65%-80%, and it is sterilized for 5 hours. The ethylene oxide sterilization indicator card placed in the sterilizer after 5 hours will change from the initial color to the preset color, for example: the initial color is pink, and the preset color is orange, so that it can ...
