Ink cleaning agent and preparation method thereof

Abstract

The invention discloses an ink cleaning agent, which is characterized by comprising the following raw materials by weight: 20-30 parts of polyoxyethylene octylphenol ether, 5-8 parts of sodium sulfonate, 1-2 parts of diethanol amine, 1-2 parts of oxalic acid, 5-7 parts of sodium benzoate, 2-4 parts of sodium methyl cocoyl taurate, 1-2 parts of sodium xylene sulfonate, 2-3 parts of dimethicone, 1-2 parts of hexamethylene tetramine, 1-2 parts of citric acid, 1-2 parts of triethanolamine oleate soap, 4-5 parts of an auxiliary agent and 100-110 parts of water. The auxiliary agent added in the invention improves the process performances of the cleaning agent, reduces the toxic and side effect and pollution to the environment. The ink cleaning agent provided by the invention has the advanategs of good ability to dissolve and dilute ink, high pollutant removal efficiency, no poison, no pollution, no inflammable or explosive property, little damage effect on roller of a printing machine, convenience for usage and low cost.

Description

technical field [0001] The invention relates to the technical field of printing cleaning, in particular to an ink cleaning agent and a preparation method thereof. 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] Existing ink cleaning agents are mainly divided into two categories: one is steam and kerosene, and the other is a special printing ink cleaning agent. [0004] Gasoline and kerosene are broad-spectrum organic solvents with small specific gravity, fast v...

AI Technical Summary

Problems solved by technology

As ink cleaning agents, gasoline and kerosene have many disadvantages: first, safety issues. The flash point of gasoline is only more than 20 degrees. If the ventilation facilities in the printing plant are not good, dangerous situations are likely to occur; As an organic solvent, kerosene has certain toxicity. If it is exposed for a long time, it will inevitably cause a certain degree of damage to the health of workers and the surrounding environment.

At present, the commonly used solvents still come from non-renewable solvent oils, such as kerosene, which have a strong smell and poor degradability, and still pose a certain threat to the environment.
