Safe environment-friendly ink detergent and preparation method thereof

Abstract

The invention discloses a safe environment-friendly ink detergent. The invention is characterized in that the detergent is prepared from the following raw materials in parts by weight: 4-5 parts of polyoxyethylene sorbitan fatty acid ester, 4-5 parts of polyoxyethylene castor oil, 6-8 parts of acetone, 4-6 parts of ethyl acetate, 2-3 parts of sodium gluconate, 1-2 parts of triethanolamine, 3-4 parts of isopropyl myristate, 1-2 parts of polydimethylsiloxane, 1-2 parts of 2-oxazolidone, 4-5 parts of magnesium sulfate, 4-5 parts of coconut oil fatty acid, 2-3 parts of tall oil fatty acid, 4-5 parts of assistant and 100-110 parts of water. The assistants are added to improve the technical properties of the detergent and reduce the toxic or side effect and environmental pollution; and the detergent has the advantages of excellent dissolution and dilution capability for inks, no toxicity, no volatilization, no harm to the human body, no corrosivity and low manufacturing cost, and is convenient to use.

Description

Technical field [0001] The invention relates to the technical field of printing cleaning, in particular to a safe and environmentally friendly ink cleaning agent and a preparation method thereof. Background technique [0002] Printing equipment needs to clean oil and ink stains regularly during the production process. The ink on the ink roller should be cleaned when changing the ink variety or after the printing task is completed. The dampening roller, screen, printing plate and font on the printing machine will be contaminated with ink during the printing process, in order to keep the printing machine normal The condition and quality of printed matter should also be cleaned for printing machinery. [0003] The existing ink cleaning agents are mainly divided into two categories: one is gasoline and kerosene, and the other is a new type of printing ink cleaning agent. [0004] Gasoline and kerosene are broad-spectrum organic solvents with low specific gravity, high volatilization sp...

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.
