Metal printing cloth-washing water

Abstract

The invention discloses metal printing cloth-washing water which is prepared from the following components in percentage by weight: 8-10% of tributyl phosphate, 2-2.5% of triethanolamine, 0.2-0.25% of a chelating agent, 2.5-3.5% of a non-ionic surfactant, 1.5-2.5% of an anionic surfactant and the balance of softened water. The metal printing cloth-washing water integrates mechanisms and properties of fusion and permeation, adsorption, emulsion, solubilization and peeling, is good in high-temperature stability and convenient and safe to use, and can be used for quickly removing printing ink stains on a rubber blanket.

Description

technical field [0001] The invention relates to the field of iron printing and printing equipment maintenance, in particular to a cloth washing water for iron printing. Background technique [0002] For metal-based metal printing and can-making processes, the printing requirements are getting higher and higher, and the graphics are becoming more and more exquisite and detailed, which leads to higher requirements for the dot transfer of blankets. How to ensure a high degree of restoration of the dots of the blanket depends on how effective the cleaning material can be. [0003] At present, the following two cleaning agents are mainly used for cleaning iron printing blankets: [0004] One is: gasoline, white starch oil cleaning agent, although this type of solvent can dissolve the ink well, but its ignition point is low, flammable, and the fire hazard is great, especially the printing and iron industry requires high temperature operation, which increases the risk factor , an...

Problems solved by technology

[0004] One is: gasoline, white starch oil cleaning agent, although this type of solvent can dissolve ink well, but its ignition point is low, flammable, and there is a great fire hazard, especially the printing and iron industry requires high temperature operation, which increases the risk factor , and volatilizes quickly, wastes seriously, and causes damage to the health of operators and pollutes the environment;

[0005] The second is: offset printing blanket cleaning agent. This type of cleaning agent is mainly suitable for cleaning blankets in paper printing process. It has high solubility for paper wool and confetti. It is smooth and has high requirements on the composition of the ink. The ink is mainly composed of synthetic resins such as phenolic resin, polyamide resin, polypropylene resin, etc., so this kind of cleaning material cannot completely remove the ink residue
