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.

Embodiment 1

[0029] The quality of each component of the cleaning agent is as follows:

[0030] name Dosage (g) cottonseed oil methyl ester 20 T-80 12 LAS 3 Butanol 5 water 100

[0031] Preparation method: Mix cottonseed oil methyl ester, T-80 and n-butanol evenly under stirring at room temperature to make phase A; mix LAS and water to make phase B. Then, under stirring, phase B was gradually added to phase A, and stirred for another 30 minutes to obtain a detergent emulsion.

Embodiment 2

[0033] The quality of each component of the cleaning agent is as follows:

[0034] name Dosage (g) rapeseed oil methyl ester 20 T-80 12 Pingping plus -0 5 LAS 3 Butanol 5 water 100

[0035] Preparation method: Mix rapeseed oil methyl ester, T-80, Pingpinga-0 and n-butanol evenly under stirring at room temperature to make phase A; mix LAS and water to make phase B. Then, under stirring, phase A was gradually added to phase B, and stirred for another 30 minutes to obtain a light yellow and transparent cleaning agent.

Embodiment 3

[0037] The quality of each component of the cleaning agent is as follows:

[0038] name Dosage (g) cottonseed oil methyl ester 20 T-80 12 AE-15 2 LAS 3 Butanol 5 water 100

[0039] Preparation method: Mix cottonseed oil methyl ester, T-80, AE-15 and n-butanol evenly under stirring at room temperature to make phase A; mix LAS and water to make phase B. Then, under stirring, phase B was gradually added to phase A, and stirred for another 30 minutes to obtain a detergent emulsion.

Abstract

An ink cleaner consists of fatty acid monoalkyl ester, water, a water soluble nonionic surfactant, an anion active agent and a cosurfactant. The ink cleaner provided by the invention has the advantages of simple preparation, stable latex, strong cleansing power and the like and is especially applicable to cleaning printing ink.

Description

technical field [0001] The invention relates to an ink cleaning agent. More specifically, the present invention relates to an environment-friendly cleaning agent for printing ink. 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 specif...
