A kind of printing ink cleaning agent and preparation method thereof

Abstract

The invention discloses a printing ink cleaning agent. The printing ink cleaning agent is characterized by comprising the following raw materials in parts by weight: 4-5 parts of fatty acid monoalkyl esters, 1-2 parts of liquid paraffin, 3-4 parts of oleic acid, 2-3 parts of potassium peroxomonosulfate, 4-5 parts of perfluoropolyether, 1-2 parts of sodium perborate monohydrate, 3-4 parts of glycerin monostearate, 1-2 parts of coconut oleic acid alkyl alcohol amine, 4-5 parts of OP-10, 4-5 parts of assistant, and 100-110 parts of water. The assistant is added to the printing ink cleaning agent, so that the processing property of the cleaning agent is improved; the toxic and side effects and the pollution to the environment are reduced. The printing ink cleaning agent disclosed by the invention is strong in cleaning capability, free of poison, free of volatilization, free of harm to a human body, free of corrosivity, low in fabrication cost, small in injury to a printing press roller, and convenient to use.

Description

technical field [0001] The invention relates to the technical field of printing cleaning, in particular to a printing 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...

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.
