Abstract

The invention discloses a water-soluble printing ink washing agent and a preparation method thereof. The water-soluble printing ink washing agent comprises the following components in percentage by mass: 5-10% of glycol monomethyl ether, 2-3% of sodium citrate, 1-2% of malic acid, 1-2% of surfynol 465, 1-2% of Arabic gum, 1-2% of triethanolamine, 0.5-1% of fatty alcohol-polyoxyethylene ether, 0.3-0.5% of sodium benzoate, 0.3-0.5% of benzotriazole, 0.3-0.5% of hexamine, 1-2% of bentonite, and the balance of deionized water. The water-soluble printing ink washing agent is free from gasoline, kerosene and other mineral oil and avoids the disadvantages of high flammable and combustible volatility and high danger of aromatic hydrocarbon; the water-soluble printing ink washing agent is small indamage to environment and people and high in dirt removing capacity; in addition, a rubber roller, a plastic cloth and other parts are prevented from surface corrosion and swelling; the service life of equipment cannot be shortened.

Description

technical field [0001] The invention belongs to the field of ink cleaning agents, in particular to a water-soluble printing ink cleaning agent and a preparation method thereof. Background technique [0002] In recent years, my country's printing industry has developed rapidly. On the one hand, the demand for the output of printed products in the market has been increasing, and on the other hand, the quality requirements for printed products have also been continuously improved. In the printing process, different product requirements require the use of different ink types. The cleaning of residual ink on printing equipment is a key process in the entire printing process, and it is an important guarantee for the production of high-quality printed matter. Therefore, efficient ink cleaning agents have always attracted the attention of the printing industry. [0003] Traditional ink cleaning agents are mainly based on mineral oils such as gasoline and kerosene, and organic solv...
