Problems solved by technology

When it is in use, the front side of the paper is first printed, and then the reverse side of the paper is printed, and the interval time in between is very short. However, the offset rotary ink of the prior art often has the problems of slow drying speed and color fading after printing, which makes it difficult to use. The adaptability of paper is poor, reducing its range of use

Abstract

The invention relates to an offset rotary ink and a preparation method thereof and belongs to the technical field of inks. The raw materials of the offset rotary ink comprise pigment, phenolic resin,polyether modified polydimethylsiloxane, propylene glycol methyl ether acetate, filler, plant oil, a low-arene high-boiling-point petroleum solvent and a drier. The raw materials are mixed and groundthrough different steps to obtain the offset rotary ink. The permeability of the offset rotary ink is improved, the offset rotary ink has a good drying property and good adhesive force and has the advantages of stable storage and low VOC discharging, and the demands for the market and environment protection are met.

Description

technical field [0001] The invention relates to the technical field of ink, and more specifically, it relates to an offset printing rotary ink and a preparation method thereof. Background technique [0002] In recent years, with the progress of the society and the development of the market, the printing ink has also been rapidly improved. The offset printing ink in the prior art generally uses asphalt as the binder. When it is in use, the front side of the paper is first printed, and then the reverse side of the paper is printed, and the interval time in between is very short. However, the offset rotary ink of the prior art often has the problems of slow drying speed and color fading after printing, which makes it difficult to use. The poor adaptability of paper reduces its range of use. Contents of the invention [0003] The purpose of the present invention is to provide a kind of offset rotary ink, which not only improves its permeability, but also makes it have good dr...
