Abstract

The invention discloses ultraviolet-curing offset printing ink and a preparation method thereof. According to the technical scheme, the ultraviolet-curing offset printing ink is characterized by being prepared from the following raw materials in parts by weight: 30-70 parts of binder A, 0-15 parts of auxiliary binder B, 0-20 parts of auxiliary binder C, 0-5 parts of modified epoxy soybean oil, 15-20 parts of pigment, 10-20 parts of filler, 5-15 parts of photoinitiator, 0.05-1 part of polymerization inhibitor, 0-1 part of wax and 0.5-5 parts of dispersing agent. The invention discloses a preparation method of the ultraviolet-curing offset printing ink. The ultraviolet-curing offset printing ink has high gloss, excellent performance and low cost and solves the technical problem that the existing common offset printing ink and common UV (ultraviolet) offset printing ink have no adhesive force on various high-grade films.

Description

technical field [0001] The invention belongs to the technical field of printing inks, and in particular relates to an ultraviolet light curing offset printing ink and a preparation method thereof. Background technique [0002] At present, the printing industry generally uses solvent-based inks for film printing production. Although UV-curable screen inks are also used for film printing in some printing factories in recent years, compared with UV offset printing inks, the printing speed is limited and the printing pattern clarity is limited. Not fine enough. Solvent-based inks generally contain 15%-50% petroleum solvents, and some plastic gravure inks even contain a large amount of aromatic solvents such as toluene. [0003] Solvent-based inks mainly have the following disadvantages: 1. The degradation rate of hydrocarbons in the natural environment is slow, and the ability of volatilized hydrocarbon gases to cause the greenhouse effect greatly exceeds that of carbon dioxide...
