Abstract

The invention relates to a formula, a preparation technology and an application of an offset printing ink. The formula of the offset printing ink comprises, by mass, 30-40% of resin oil, 20-30% of gummy oil, 5-10% of a filler, 15-20% of a pigment, 0.3% of a drying agent and 1-5% of an assistant 1#, wherein the resin oil can be a phenolic resin or an alkyd resin; the pigment can be an organic pigment; the filler can be calcium carbonate; the assistant 1# can be an antioxidant; and the gummy oil can be phenolic resin oil or octyl phenol resin oil. The preparation technology comprises the following steps: adding the above raw materials to a bucket according to the formula, stirring for 40min, grinding after the obtained stirred mixture is qualified, adjusting indexes of the mixture after the fine of the mixture is qualified, and packaging after the indexes are qualified. The offset printing ink can be applied to paper printing. The offset printing ink has the advantages of strong luster, fast fixation speed, low cost, good wear resistance and cost saving.

Description

technical field [0001] The invention belongs to offset printing ink formula and its preparation process. Background technique [0002] The production of offset printing inks, the existing offset printing inks have high cost and poor printing adaptability, and the preparation process is complicated, and the manufactured inks have slow fixing speed and poor scratch resistance. [0003] At present, offset printing inks are mainly composed of resin oil, pigments, fillers, additives, and other substances after grinding. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a formulation of offset printing ink with good performance and its preparation process, which solves the disadvantage of slow fixing speed and poor scratch resistance of traditional offset printing ink. [0005] A kind of offset printing ink formula of the present invention comprises following components (mass percentage): [0006] Resin oil: 30-40...
