Water-soluble printing-ink detergent and preparation process

Abstract

The invention is a water-soluble printing ink washing agent and the making technique. It firstly adds softened water to mixing jar and heats to 35-45 deg.C, adds polyoxyethylene octane phenolic ether or polyoxyethylene nonylphenol, 3-5% and trihydroxy ehhylamine, 2-6%, to the mixing jar, fully stirs for 15-30 minutes, then adds butyl fibre-dissolving agent, 3-9%, to the mixed solution, stirs for 20-30 minutes to mix evenly, and then uses thin hydrochloric acid, 2%, to adjust the pH of the washing agent to 7-8. The washing efficiency is high and the application range is wide.

Description

technical field [0001] The invention relates to a cleaning agent for cleaning printing inks such as printing machines, printing plates, rubber rollers and blankets, in particular to the formula and preparation process of the water-soluble ink cleaning agent. Background technique [0002] In the printing industry, most of the inks used to clean the inked parts of printing machines, printing plates, rubber rollers, and blankets use organic solvents such as kerosene, gasoline, alcohol, acetone, and ethyl acetate as cleaning agents. Combustible, explosive, polluting the environment, endangering human health, can cause damage or defects such as dissolution, swelling, corrosion, loss of light, cracking or foaming on the surface of the cleaned material, and the cleaning effect is not ideal, the surface of the cleaned part is often If there is floating dirt, as time goes by, you will find that the ink stains accumulated in certain parts of the machine that are often inked will becom...

AI Technical Summary

Problems solved by technology

With the continuous emergence of water-soluble ink cleaning agents, we have also discovered the disadvantages of such cleaning agents: some have a narrow scope of application, such as only cleaning rubber rollers; some damage the skin; some corrode metals; The cleaning effect is not good. After cleaning the machine, the workers' hands are covered with ink and it is difficult to clean, which affects the printing of the machine and wastes manpower. There are also disadvantages such as complicated formula and production process, and high processing cost.
