In the prior printing industry, organic solvents such as gasoline, acetone, alcohol, kerosene, n-hexane, trichloroethane, trichloroethylene, xylene and the like are mostly used for cleaning, and although the organic solvents are low in price and strong in cleaning power, the organic solvents are strong in volatility, inflammable and explosive, pollute the environment, harm the health of human bodies, and easily dissolve and corrode the surface of the cleaned equipment. The amount of pollution of global Volatile Organic Compounds (VOC) caused by ink has been counted to several tens of thousands of tons every year. In addition, the other commonly used plate washing liquid takes ethyl acetate as a main component, has strong acidity, and has better cleaning capability on commonly used alkaline printing ink, but the strong acidity of the plate washing liquid also has stronger corrosion effect on a metal printing plate, is not beneficial to protecting the printing plate, and has stronger corrosion to human skin. In order to overcome the disadvantages of the conventional ink cleaning agent, a novel plate washing solution suitable for printing ink of a flexographic plate needs to be researched.
