Abstract

The invention relates to fluorescent flat plate offset printing ink and a preparation method thereof. The fluorescent flat plate offset printing ink is prepared from, by weight, 25-30 parts of alkyd resin, 10-25 parts of petroleum resin, 4-6 parts of methyl palmitate, 3-5 parts of abietate, 10-15 parts of fluorescent powder, 1-3 parts of anti-settling agent, 0.4-0.6 part of antioxidant, 1-2 parts of butanol, 0.3-0.5 part of defoamer and 6-8 parts of varnish. The fluorescent flat plate offset printing ink is free of toxicity, odorless, stable, reliable and good in smoothness, fluorescence is bright in color, good in dispersing performance and free of migration, the color retention for longer time can be achieved in the using process, the used components are poisonless and harmless, the environmental protection effect is achieved, the used substances are convenient to sample, and the ink is suitable for being used for printing.

Description

technical field [0001] The invention relates to a fluorescent lithographic offset printing ink and a preparation method thereof, belonging to the technical field of printing. Background technique [0002] The manufacture of ink is a complex chemical engineering, and its materials involve chemical changes such as organic polymer synthesis and redox, diazotization, displacement reaction, and complexation reaction. At the same time, it involves mechanics, optics, color science, surface chemistry and other subjects. The first is the manufacture of various pigments and the manufacture of fillers. The second is the manufacture of various synthetic resins and the production of various types of linking materials, dissolving solid resins in vegetable oil, mineral oil, and solvent media. The third is the manufacture of ink. These three processes are interrelated, affect each other, and are indispensable. In the process of offset printing, the quality requirements of the ink are al...
