Treatment process for improving fluidity of offset printing ink

Abstract

The invention relates to the technical field of offset printing ink production, and discloses a treatment process for improving the fluidity of offset printing ink, which comprises the following steps: S1, raw material preparation: firstly, preparing each printing ink raw material, and weighing according to the proportion of the raw materials; the ink is prepared from the following raw materials in parts by mass: 41 to 45 parts of hard resin, 6 to 7 parts of soft resin, 12 to 14 parts of solvent, 15 to 16 parts of pigment, 15 to 18 parts of dry vegetable oil, 4 to 5 parts of slipping agent, 1.3 to 2 parts of filler and 1 to 2 parts of additive, and S2, processing equipment is prepared, the raw materials prepared in the step S1 are added into the processing equipment according to the processing technology sequence, and the processing equipment is a reaction kettle. The treatment process for improving the flowability of the offset printing ink has the advantages that the flowability of the offset printing ink can be effectively improved, smooth ink supply of the offset printing ink during printing is guaranteed, the situation of ink shortage is avoided, and the printing quality of the offset printing ink is improved.

Description

technical field [0001] The invention relates to the technical field of offset printing ink production, in particular to a treatment process for improving the fluidity of offset printing ink. Background technique [0002] With the rapid development of the packaging and printing industry, the ink industry has grown rapidly accordingly. Among them, offset printing inks have incomparable advantages over traditional inks, and have been widely used in cigarette packs, wine packs, cosmetics packs, pharmaceutical packs or other Dry glue trademark and other fields. The excellent performance of offset printing ink is as follows: first, it is very suitable for high-speed operation, good printing suitability, fast curing speed, high production efficiency, generally only needs 1 / 10 second to dry completely and fix on the surface of the substrate; second, improve The performance of the product has good water resistance, oil resistance and anti-fouling performance; third, it has excellent...
