Preparation method of environment-friendly printing ink cleaner

Abstract

The invention discloses a preparation method of an environment-friendly printing ink cleaner and belongs to the technical field of printing ink cleaners. Potato starch, ethylene glycol, n-dodecanol and the like are used as raw materials and subjected to a heating reaction, then the pH of a mixed solution is adjusted, reduced pressure distillation is performed, starch-based dodecyl glycoside is prepared, a mixed microemulsion is prepared from starch-based dodecyl glycoside, sodium dodecyl sulfate, n-butyl alcohol, deionized water and the like, D-limonene, ethanolamine, the mixed microemulsion and the like are placed in a high-shear dispersion emulsifying machine for stirring emulsification, the mixture is left to stand and cooled, and the environment-friendly printing ink cleaner is prepared. The raw materials of the printing ink detergent are environment-friendly, the toxic and side effects of the detergent are effectively reduced, damage to human health and the environment is avoided, and the printing ink detergent is high in deterging speed, high in detergency efficiency and better in stability, can effectively protect base materials and prolong the service life of equipment and has broad application prospect.

Description

technical field

[0001] The invention discloses a preparation method of an environment-friendly ink cleaning agent and belongs to the technical field of ink cleaning agent preparation. Background technique

[0002] The main body of the world's printing industry is offset printing, which is a printing method that transfers the graphics on the printing plate to the substrate by means of rubber (blanket). In order to ensure the normal operation of printing equipment, it is necessary to carry out regular cleaning and maintenance of printing equipment, such as routine cleaning after printing every day, cleaning before changing ink color, and thorough maintenance and cleaning after using for a period of time, so ink cleaning agent is printing A very important consumable in the field.

[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...
