Embodiment 1

[0040] In this example, the environmentally friendly water-based ink cleaner is formulated from the ingredients in the table below.

[0041] Each group distribution ratio of table 1 embodiment 1

[0042]

[0043] Weigh each component according to the above ratio, at room temperature, first mix Tween40 and Tween80, then add sodium fatty acid methyl ester sulfonate, alkyl glycoside 1214, then add layered crystal disilicate sodium silicate, ethylenediamine Disodium tetraacetate, add water and stir thoroughly, then add urea, sodium gluconate and benzotriazole, and finally add D-limonene, stir and dissolve completely, and the obtained uniform clear liquid is water-based printing ink cleaning agent.

[0044] After detection and analysis of the present invention, the cleaning efficiency reaches 100%, and each index meets the standard of the national water-based cleaning agent. The specific detection data is shown in the following table 2:

[0045] Table 2 embodiment 1 gained prod...

Embodiment 2

[0049] In this example, the environmentally friendly water-based ink cleaner is formulated from the ingredients in the table below.

[0050] Each group distribution ratio of table 3 embodiment 2

[0051]

[0052] Preparation method is identical with example 1. The cleaning effect and performance indicators are the same as those in Example 1, and all indicators meet the national water-based cleaning agent standards. The specific test data are shown in Table 4 below.

Abstract

Aiming at the disadvantages that the cleaning effect of water-based ink cleaning agents on the current market is not ideal, the surface of cleaned workpiece is corroded by added strong alkaline assistants, the environment is easily polluted and the like, the invention provides an environment-friendly water-based ink cleaning agent which has high cleaning efficiency, does not easily corrode the surface and is easily biodegrade, and a preparation method of the ink cleaning agent. The water-based ink cleaning agent comprises the following components in percentage by mass: 5-10% of an anionic-cationic surfactant compound, 6%-15% of a polar solvent, 2%-5% of a solubilizer, 5%-10% of other auxiliary agents and the balance of water.

Description

[0001] Technical field: [0002] The invention relates to an ink cleaning agent for cleaning printing ink on printing machinery, printing master plates, ink rollers and blankets. More specifically, it is an environmentally friendly water-based ink cleaning agent. [0003] Background technique: [0004] As an important part of production, the printing industry must consider the use of ink and the cleaning process in its printing process. Traditional ink cleaning agents mainly use organic solvents such as kerosene as the main solvent, which has a low flash point and is flammable and explosive, and is gradually eliminated. However, the new semi-water-based ink cleaning agent mainly mixes oil and water. Although it has a higher flash point and is safer than gasoline and kerosene, it will break the emulsion during use and cause oil and gas to escape, affecting safe production and polluting the environment. Therefore, the production of water-based cleaning agents can not only aband...
