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 being made of the following raw materials, by weight, including 3-4 parts of tall oil, 3-4 parts of sodium dodecyl benzene sulfonate, 1-2 parts of sodium hydroxide, 2-3 parts of potassium pyrophosphate, 1-2 parts of imidazoline, 10-12 parts of isopropyl-ketone, 2-3 parts of tetradecyl trimethyl ammonium chloride, 1-2 parts of stannous mono-sulphate, 1-2 parts of diisopropyl naphthalene sulfonic acid sodium salt, 4-5 parts of auxiliaries and 100-110 part of water. According to the printing ink cleaning agent, since the auxiliaries are added, the processing property of the cleaning agent is improved, and the toxic and side effect of the printing ink cleaning agent and environmental pollution caused by the printing ink cleaning agent are reduced; the printing ink cleaning agent is good in cleaning capacity, high in decontamination efficiency, safe, nontoxic, harmless to a user, safe to transport, and free of environmental pollution; due to the fact that the tall oil is used, energy resources are saved, and production cost is lowered.

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 printing ink cleaning agent mainly is divided into two classes: a class is steam, kerosene, and another kind is the special printing ink cleaning agent. [0004] Gasoline and kerosene are broad-spectrum organic solvents with small specific gravi...

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.
