Clearing process for water-based screen printing ink

Abstract

The invention discloses a clearing process for water-based screen printing ink. The clearing process mainly comprises the following steps of soaking-ultrasonic treatment-washing-drying. The inventionfurther discloses an ink plate cleaner. The ink plate cleaner comprises the following components of, by weight, 80-90% of water, 4-8% of an interface active auxiliary semi-finished product, 4-8% of apH regulator and 1-5% of a wetting agent, wherein the interface active auxiliary semi-finished product comprises the following components of, by weight, 75-85% of water, 14-24% of an interfacial active agent, 0.2-0.7% of a defoaming agent and 0.5-1% of an antibacterial agent. An ink screen printing plate can be washed to be clean through a high-pressure water gun after being soaked by using the prepared ink plate cleaner, special treatment does not need to be performed, the cleaning process is simple, energy is saved, and the environment is protected; and the prepared ink plate cleaner is highin stability, and has relatively high practicability and economic value.

Description

technical field [0001] The invention relates to the technical field of printing ink cleaning, in particular to a cleaning process of water-based screen printing ink. Background technique [0002] During the production process, printing equipment needs to be regularly cleaned of dirt such as oil stains and ink stains. When changing the ink type or after the printing task is completed, the ink on the ink roller needs to be cleaned, and the dampening roller, screen, printing plate and font on the printing machine will be contaminated with ink during the printing process. In order to maintain the normal operation of the printing machine The state and quality of printed matter should also be cleaned by printing machinery. [0003] In the printing industry, it is often used to clean parts with ink such as printing plates, rubber rollers, and blankets of printing machinery with organic solvents such as gasoline, kerosene, acetone, and alcohol; such cleaning agents are flammable an...
