Problems solved by technology

[0003] At present, most printing companies use gasoline and kerosene partially or completely as ink cleaning agents. When gasoline and kerosene are used as ink cleaning agents, such cleaning agents have the defects of being flammable, explosive, polluting the environment, and endangering human health. It is not conducive to the safety and labor protection of workers at work, and after using this kind of cleaning agent, the ink refillability of the rubber roller will become poor

preparation example Construction

[0016] The preparation technology of described printing ink cleaning agent, comprises the following steps:

[0017] (1) Add demineralized water into the mixing tank, heat it to 46-55°C, and keep it warm;

[0018] (2) Octylphenol polyoxyethylene ether (TritonX-100), oleic acid, sodium oleate, oil-soluble flavor (oil-soluble food flavor, contains hydrophobic groups, dissolves ink, and produces fragrance) by weight ratio After weighing, add to the mixing tank and stir for 15-25min;

[0019] (3) Add sodium alkylbenzene sulfonate (LAS) into the mixed solution prepared in step (2), and stir for 15-25 minutes to obtain a cleaning agent for printing ink.

[0020] The following are several specific examples of the present invention to further describe the present invention, but the present invention is not limited thereto.

Embodiment 1

[0022] This embodiment is made from the following mass fraction raw materials:

[0023] 15 parts of octylphenol polyoxyethylene ether;

[0024] 15 parts of oleic acid

[0025] 5 parts sodium oleate

[0026] 5 parts oil-soluble essence

[0027] Sodium alkylbenzene sulfonate 10 parts

[0028] 50 parts of demineralized water,

[0029] Preparation:

[0030] (1) Weigh the demineralized water into the mixing tank to 46°C and keep it warm;

[0031] (2) Weigh octylphenol polyoxyethylene ether, oleic acid, sodium oleate, and oil-soluble essence, and stir for 25 minutes;

[0032] (3) Weigh the sodium alkylbenzene sulfonate, add the mixture, and stir for 25 minutes to make a milky white liquid.

Embodiment 2

[0033] Example 2: Best Practice

[0034] This embodiment is made from the following mass fraction raw materials:

[0035] 20 parts of octylphenol polyoxyethylene ether;

[0037] 5 parts sodium oleate

[0038] 5 parts oil-soluble essence

[0039] Sodium alkylbenzene sulfonate 10 parts

[0040] 50 parts of demineralized water,

[0041] Preparation:

[0042] (1) Weigh the demineralized water into the mixing tank to 50°C and keep it warm;

[0043] (2) Weigh octylphenol polyoxyethylene ether, oleic acid, sodium oleate, and oil-soluble essence, and stir for 20 minutes;

[0044] (3) Weigh the sodium alkylbenzene sulfonate, add the mixture, stir for 20 minutes, and make a milky white liquid.

Abstract

The invention relates to a printing ink cleaning agent for washing printing ink of printing machines, printing plates, rubber covered rollers, rubber cloth and the like and a preparation process of the printing ink cleaning agent. The printing ink cleaning agent is composed of the following raw materials by weight 15-25% of symplectic alkyl phenol polyethylene glycol ether, 5-15% of oleic acid, 3-7% of sodium oleate, 2-8% of oil soluble essence, 5-15% of sodium alkyl benzene sulfonate and the balance of softened water. According to the printing ink cleaning agent and the preparation process provided by the invention, an organic solvent such as gasoline and kerosene can be replaced and the safety, high efficiency and environmental protection can be realized, and hydrophobic groups in emulsion can well dissolve oiliness content in the ink to achieve washing effects. The printing ink cleaning agent is simple in preparation process, and has the advantages of being low in cost, simple in preparation process, free of damage to the rubber covered rollers, non-ignitable, good in clearing performance, free of damage to skin and the like compared with the existing cleaning agent.

Description

technical field [0001] The invention relates to a cleaning agent for cleaning printing inks such as printing machines, printing plates, rubber rollers and blankets, and a preparation process. Background technique [0002] As we all know, the main body of the world's printing industry is offset printing, and offset printing ink is transferred to the substrate through ink rollers and blankets, while ink rollers and blankets are durable goods. In order to ensure the normal operation of the equipment, regular cleaning and maintenance are very important, including: routine cleaning after the end of each day; cleaning before changing the ink color; regular and thorough maintenance and cleaning. Therefore, ink cleaning agent is a very large conventional consumable in the printing field. [0003] At present, most printing companies use gasoline and kerosene partially or completely as ink cleaning agents. When gasoline and kerosene are used as ink cleaning agents, such cleaning agen...
