Abstract

The invention discloses a water-base printing ink abluent with rust-proof function, which is characterized by the following: adopting water as substrate; adding surface activator BEE, polyoxyethylene ether, inorganic alkaline and transparent liquid of fatty acid ester with 4-8 carbon atoms according to specific proportion.

Description

Technical field [0001] The invention relates to a printing ink cleaning agent, in particular to a water-based printing ink cleaning agent. Background technique [0002] The cleaning agent traditionally used for cleaning printing ink is gasoline or kerosene. In order to overcome its shortcomings of being flammable, explosive, and polluting the environment, people have developed a variety of new printing ink cleaning agents. There are mainly four types: mixed solvent type, water Cleaning agents, oil-in-water emulsions and semi-water-based cleaning agents, etc. The mixed solvent cleaning agent mainly utilizes the dissolution and cleaning effect of gasoline and kerosene, and adds a non-volatile high-boiling solvent to the formula, thereby improving the safety during the cleaning process without affecting the cleaning effect. The cleaning effect of the water-based cleaning agent is completed by the joint action of the added surfactant and alkaline additives. Oil-in-water emulsi...
