Development Of W/O Emulsion Type Printing Ink Cleaner

Because of the big dosage, printing ink cleaner as the ink assistant equipment which can be easily ignored, it's economy benefit and society benefit can not be neglect. Printing ink cleaner used past in the print industry was solvent such as gasoline, kerosene, aether, ester, halogen ate hydrocarbon and so on. Although these low cost solvent clean fast, it's flammability, easy to explode, danger to deposit and us. So a new printing ink cleaner which use water to substitute oil is safety, good to environment, effect and saving energy.On the basis of HLB value of emulsifying agent, an emulsifying agent was properly selected according to a certain oil-phase. A kind of multi-components combing emulsifying agent which had highly emulsifying ability to kerosene of 200# was achieved by orthogonal experiments. The results showed that synergistic effects which was caused by multi-components emulsifying agents lead to the emulsifying efficiency and effects of combining system much higher than that of single agent. From the preparing experiments of emulsifying solution, the results find that emulsifying agent was the decisive factor of emulsifying solution type, emulsifying efficiency, emulsifying effect and the stability. Emulsifying conditions also had great effects on the stability of emulsifying solution and the stability prolong one month after the conditions optimization.Development of W/O emulsion type printing ink cleaner in the lab had excellent ability of dissolution, infiltration and scrubbing to wet ink. The technical condition of emulsification is simple, geniality, easy to control, so it had great value to generalize.
