Abstract

The invention discloses offset ink and a preparation method thereof.The offset ink comprises, by weight parts, 10-20 parts of pigment, 40-50 parts of binder, 5-8 parts of antiwear agent mixture, 3-4 parts of cerate and 2-10 parts of auxiliaries, wherein the antiwear agent mixture comprises, by weight parts, 20-30 parts of resin oil, 35-45 parts of silane coupling agent and 3-4 parts of antiwear agent.By adoption of the antiwear agent mixture and the adding of the silane coupling agent, through reaction and self-blend crossover, as well as crossover with solidified resin, a network shape is formed in the offset ink, and the antiwear performance of the entire offset ink is improved; and the offset ink is simple in preparation steps and low in process cost.

Description

technical field [0001] The invention belongs to the field of offset printing, and in particular relates to an offset printing ink and a preparation method thereof. Background technique [0002] With the progress of the printing industry, the continuous improvement and improvement of printing technology and printing equipment, offset printing has been favored by its unique advantages, such as fast and convenient plate making, low cost, high printing quality, wide range of paper use, and large printing quantity shrinkability. Favored by printing manufacturers at home and abroad, it has developed rapidly and extensively, and then occupies a leading position in the international printing industry, and offset printing ink has also developed rapidly. [0003] As the most important printing material for information reproduction, ink should have good printability during printing. Offset printing ink is mainly composed of colored pigments (dyes, etc.), binders, fillers and additives...
