Problems solved by technology

There is a small amount of water-based ink cleaning agent preparation technology in China, but its overall effect is not satisfactory. The cleaning effect on blankets and rollers is not good, or increasing the alkalinity of the cleaning agent can improve the cleaning effect. At the expense of strong corrosion of printing equipment, printing production costs cannot be minimized
[0005] Therefore, solving the existing problems of existing water-based ink cleaning agents has become a technical problem to be solved urgently in this field. The Tween series surfactant with good cleaning effect of the present invention has not yet been reported in the field of printing ink cleaning agents.

preparation example Construction

[0043] In the preparation method of the water-based printing ink cleaning agent, each component is weighed according to the stated ratio, and at 25°C, the surfactant, the builder and the solubilizer are first added to the water, and the components are fully stirred to make the components After it is completely dissolved, add anti-redeposition agent, anti-corrosion agent, and water softener. After the dissolution is complete, filter the filtrate, and the obtained filtrate is water-based printing ink cleaning agent.

[0044] The raw materials used in the present invention are all commercially available products. In order to make the present invention easy to understand, the present invention will be further described below in conjunction with specific examples.

Embodiment 1

[0046] Water-based printing ink cleaning agent, including the following raw materials in terms of mass percentage:

[0047] Table 1 Example 1 distribution ratio of each group

[0048]

[0049] The preparation method of this example: Weigh each component according to the above ratio, and at 25°C, first mix Tween-80, Tween-85, fatty alcohol polyoxyethylene ether sodium sulfate, sodium chloride, sodium sulfate and isopropyl Add sodium benzenesulfonate into water, stir well to make all components completely dissolved, then add triethanolamine, benzotriazole and 4A zeolite, after the dissolution is complete, filter and take the filtrate, and the obtained uniform, clear and transparent liquid is water Based printing ink cleaner.

[0050] The product obtained in this embodiment is tested and analyzed, and the cleaning efficiency reaches 100%, and each index meets the standard of the national water-based cleaning agent. The specific testing data is shown in the following table 2: ...

Abstract

The invention provides a water-based printing ink cleaning compound and a preparation method thereof. The cleaning compound comprises the following raw materials by mass: 12 to 20% of surfactants, 1 to 5% of a builder, 0.5 to 2% of a solubilizer, 0.5 to 4% of redeposition resisting agent, 0.5 to 3% of an anticorrosive agent and 1 to 2% of a water softener, with the balance being water. According to the invention, a Tween series of nonionic surfactants are subjected to homologue complex formulation, so cleaning of printing ink scale is improved; a great amount of nonionic surfactants are cooperatively used with a small amount of nonionic surfactant, so surface tension of a solution is further reduced and cleaning efficiency is improved; moreover, addition of a neutral electrolyte sodium chloride enables surface activity of three surfactants to be improved simultaneously and cleaning capability of the whole system of the cleaning compound to be greatly improved.

Description

technical field [0001] The invention belongs to the field of cleaning agents for printing inks, in particular to a water-based cleaning agent for printing inks. Background technique [0002] In recent years, my country's printing industry has developed rapidly. At the same time, ink cleaning agents, as the most commonly used auxiliary materials in printing, are in increasing demand. A quality ink cleaner is critical to print production. [0003] Traditional ink cleaning agents, which use organic solvents such as gasoline and kerosene as the main agent, have potential safety hazards such as flammability and explosion, and are highly volatile when used, seriously polluting the printing environment and endangering the health of workers, while consuming a large amount of petroleum resources . The semi-water-based printing ink cleaning agent reduces the content of organic solvents, but there are still many disadvantages such as polluting the environment, endangering human healt...
