Single-sheet non-skinning oil ink

Abstract

The invention relates to a single-sheet non-skinning oil ink which aims at realizing slow drying on a machine and fast drying on paper. The oil ink comprises the following components by weight percent: 10-25% of pigments, 0.1-5% of extender pigment, 20-30% of vegetable oil, 15-30% of mineral oil, 25-35% of resin, 0.5-3% of assistants, 0.5-2% of wax powder and 0.3-1% of gelatinizing agent, whereinthe pigments are the pigments with various colors which are red, yellow, blue and black generally; the extender pigment is any one of bentonite and calcium carbonate or the mixture of the two with anyproportion; the vegetable oil is bleaching sesame oil; the mineral oil is high-boiling point kerosene; the resin is the mixture of rosin modified phenolic resin and alkyd resin; the assistants are antioxidant and drying oil; the wax powder is polyethylene micro-powder wax; and the gelatinizing agent is liquid aluminum AO-3. The oil ink is prepared by adopting the production technology of the conventional offset printing oil ink.

Description

technical field [0001] The invention relates to a non-skinning ink for sheet-fed paper. Background technique [0002] For most lithographic sheet-fed offset printing manufacturers, they are currently using ordinary sheet-fed inks. When the ink is produced by the manufacturer, a certain proportion of drying additives are added to ensure the drying performance of the ink. Easy skinning is not convenient for storage. For printing manufacturers, the speed of skinning is too fast during the printing process. The machine rollers need to be cleaned after a period of time, and this special cleaning agent pollutes the environment, and the emission of volatile organic compounds is harmful to the human body and can easily cause cancer. If the opened package is left unused, skinning will easily occur, which will affect normal use and cause waste. Therefore, the traditional sheet-fed ink not only pollutes the environment and damages human health, but also causes waste of manpower, finan...

If the opened package is left unused, skinning will easily occur, which will affect normal use and cause waste. Therefore, the traditional sheet-fed ink not only pollutes the environment, damages human health, but also causes waste of manpower, financial resources and material resources.
