Cleaning agent of printing ink and preparation method thereof

Abstract

The invention discloses a cleaning agent of printing ink. The cleaning agent is characterized by comprising the following materials in parts by weight: 1-3 parts of diethanol amine, 1-2 parts of oxalic acid, 5-10 parts of sodium benzoate, 9-12 parts of propylene glycol, 13-15 parts of alcohol, 6-8 parts of polyethylene glycol, 1-2 parts of coconut fatty acid alkanolamide, 3-5 parts of polysorbate 80, 2-3 parts of calcium sorbate, 1-2 parts of sodium hypochlorite, 10-12 parts of dipropylene glycol mono butyl ether, 4-5 parts of additives and 100-110 parts of water. The cleaning agent disclosed by the invention has the advantages that due to addition of the additives, the processing property of the cleaning agent is improved, and the toxic and side effects and the pollution to environment of the cleaning agent are alleviated; the ink dissolving and diluting capabilities of the cleaning agent are excellent, no toxicity and pollution are caused, the cleaning agent is not flammable and combustible, the damage on rubber rollers of a printing machine is low, the use is convenient and the cost is low.

Description

technical field [0001] The invention relates to the technical field of printing cleaning, in particular to an ink cleaning agent for printing 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 gr...

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.
