Abstract

The invention relates to the technical field of printing, and particularly discloses offset printing ink and a preparation method thereof. The offset printing ink is prepared from pigment, a binder, linseed oil, tetradecanol, a wear-resistant agent, methyl cellulose and the like as raw materials; the binder at least comprises phenolic resin, melamine copolymer resin and rosin, the wear-resistant agent is prepared by taking oil-containing resin, calcium chloride, white graphite, pumice stone, microcrystalline wax and a silane coupling agent as raw materials through heating and mixing. The wear resistance of the offset printing ink can be effectively improved through matched use of the white graphite, the pumice stone, the microcrystalline wax and the silane coupling agent. The preparation method provided by the embodiment of the invention is simple, solves the problem of insufficient wear resistance of the existing offset printing ink, and has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an offset printing ink and a preparation method thereof. Background technique [0002] With the continuous development of printing technology, the variety of inks is also increasing. At present, common inks are divided into letterpress printing inks, lithographic printing inks, gravure printing inks, stencil printing inks, and special printing inks. Among them, offset printing ink is a kind of lithographic ink, which is suitable for printing on various offset printing machines. The quality of offset printing ink directly affects the performance of offset printing products, and is also of great significance to the advancement of human civilization. [0003] At present, most of the existing offset printing inks are composed of binders, pigments, fillers, additives and solvents. However, the existing offset printing inks have the following disadvantages in actual use: the existi...
