Novel detergent for printing ink and preparation method of detergent

Abstract

The invention discloses a novel detergent for printing ink. The novel detergent for printing ink is characterized by being prepared from the following raw materials in parts by weight: 30-34 pars of kerosene, 10-12 parts of acetone, 4-6 parts of ethyl acetate, 3-5 parts of tween 20, 1-2 parts of pine tar, 1-2 parts of cyanuric acid zinc, 1-2 parts of lignosulfonate, 1-2 parts of 2,6-Di-tert-butyl-4-methylphenol, 5-7 parts of glycolic acid, 10-12 parts of nitroethane, 4-5 parts of an addition agent, and 100-110 parts of water. Due to the addition of the addition agent, the processing property of the detergent is improved, and toxic and side effects and contamination to environment are reduced; the novel detergent for printing ink has strong cleaning capacity, has no toxicity, is unharmful to human bodies, has no corrosivity, is low in production cost, has small use level compared with pure solvent type detergents such as kerosene and gasoline, has low volatilization speed, can fully exert the cleaning effect and greatly saves the use level.

Description

technical field [0001] The invention relates to the technical field of printing cleaning, in particular to a novel printing ink cleaning agent and its preparation method. 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...

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.
