Anti-skinning agent special for ink fountain and ink distribution system of offset press

Abstract

The invention relates to a special anti-skinning agent of duct and ink transfer system of offset press, which can be used in duct and roller of ink transfer system of water offset press or dry offset press. The anti-skinning agent contains polyfunctional group solvent ethanol 66-68 percent, TX-10 surface activator 1.2-1.4 percent, eldopaque 1.8-2.0 percent, methyl carbitol 21-23 percent, and 210 mineral oil 8-10 percent. It ensures that there is no needing of cleaning duct and ink transfer system within 20 hours after halting water offset press or dry offset press, and that prevent ink from curing and skinning, thus it releases the labor intensity, and improves the production efficiency of printer. And it has an obvious effect on decreasing the consume of ink and improving the quality of printed matter.

Description

technical field [0001] The invention relates to an anti-skinning agent, in particular to an anti-skinning agent specially used for ink fountains and ink transfer systems of offset printing machines. Background technique [0002] Water offset printing or dry offset printing machine will have 16 hours to 8 hours of downtime after continuous 8 hours or 16 hours of printing production every day. During this period, the ink on the ink fountain and ink roller of the offset printing machine is easy to solidify. Skinning will affect the next normal printing. Under the condition of long-line product printing, especially in the banknote printing industry, the ink fountain and ink transfer system must be cleaned after printing every day, and the same ink is used for production on the second day of long-line product printing. This makes printing workers increase the workload of cleaning ink during the printing process, disrupts the normal working state of the ink fountain and ink trans...
