Problems solved by technology

In addition, another commonly used plate washing solution currently uses ethyl acetate as the main component, which is strongly acidic and has a good cleaning ability for commonly used alkaline printing inks. Acid also has a strong corrosive effect on the metal printing plate, which is not conducive to the protection of the printing plate, and strong acid is also highly corrosive to human skin

Abstract

The invention discloses a flexible resin plate washing liquid and a preparation method thereof. The flexible resin plate washing liquid comprises the following components by weight: 20-30 parts of a nonionic surfactant, 10-15 parts of an anionic surfactant, 3-8 parts of a dispersing agent, 2-5 parts of a washing auxiliary agent, 3-5 parts of a cosolvent, 1-2 parts of an antifoaming agent, and 130-200 parts of water. By adding the dispersing agent into the system, the polyethylene glycol 200 can well form a stable dispersing system with the dispersoid with lower hydrophilic-lipophilic balance value; and the polyethylene wax can effectively block mutual adsorption of ink particles, and the polyethylene wax and the ink particles have better dispersity after being compounded.

Description

technical field [0001] The invention relates to the technical field of flexible resin plates, in particular to a washing solution for flexible resin plates and a preparation method thereof. Background technique [0002] Printing is a reproduction technology that transfers the ink on the surface of the printing plate to the reproduced material by mechanical force. Paper, ink, and printing plate are the three major elements that affect the printing quality. Among them, the printing plate is the key link among the three. Its quality directly affects product quality and production cost. Therefore, how to effectively clean the printing process after the completion The ink that adheres to the printing plate is crucial. [0003] In the past, organic solvents such as gasoline, acetone, alcohol, kerosene, n-hexane, trichloroethane, trichloroethylene, and xylene were mostly used in the printing industry for cleaning. Although these organic solvents are cheap and have strong cleaning ...
