Novel detergent for printing ink as well as preparation method thereof

Abstract

The invention discloses a novel detergent for printing ink. The detergent is characterized by being prepared from the following raw materials in parts by weight: 3-4 parts of white oil, 10-12 parts of ethanol, 4-5 parts of acetone, 10-12 parts of isopropanol, 3-4 parts of borax, 3-4 parts of mirabilite, 2-3 parts of sodium carbonate, 1-2 parts of sodium tripolyphosphate, 12-15 parts of polyoxyethylated castor oil, 1-2 parts of sodium laurylsulfate, 2-3 parts of triethanolamine borate, 1-2 parts of sodium dodecyl benzene sulfonate, 4-5 parts of an assistant and 100-110 parts of water. The assistant is added to improve the technical performance of the detergent and reduce the toxic and side effects and the environmental pollution. The detergent disclosed by the invention has excellent dissolving and diluting capacity to printing ink, and is free from toxicity and pollution, nonflammable and incombustible, less in damage to the rubber covered roller of a printer, convenient and safe to use, and applicable to popularization in a wide range.

Description

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

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.
