A kind of ink cleaning agent and preparation method thereof

Abstract

The invention discloses an ink cleaning agent, which is characterized in that it is made of the following raw materials in parts by weight: octylphenol polyoxyethylene ether 20-30, sodium sulfonate 5-8, diethanolamine 1-2, oxalic acid 1-2 2. Sodium Benzoate 5‑7, Sodium Methyl Cocoyl Taurate 2‑4, Sodium Xylene Sulfonate 1‑2, Dimethicone 2‑3, Hexamethylenetetramine 1‑2, Citric Acid 1-2, oleic acid triethanolamine soap 1-2, auxiliary agent 4-5, water 100-110; the present invention adds auxiliary agent, improves the process performance of cleaning agent, reduces its toxic side effects and environmental pollution; the present invention It has excellent solubility and dilution ability for ink, high decontamination efficiency, non-toxic, non-polluting, non-flammable and explosive, has little damage to printing machine rubber rollers, easy to use, 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.
