Problems solved by technology

[0005] However, due to the need to take into account the wettability of pigments, unsaturated polyester resins are often used as the main resin for UV offset printing inks on the market, and the curing speed is slow.
And offset printing ink contains heavy metals, which are extremely harmful to the human body and the environment

Abstract

The invention discloses UV (Ultraviolet) curing adhesive printing ink which comprises the following components in parts by weight: 20-30 parts of urethane acrylate, 25-35 parts of modified epoxy resin, 1-10 parts of polyvinylpyrrolidone, 10-20 parts of polyether acrylate, 2-8 parts of a photoinitiator, 1-5 parts of a dispersing agent, 3-7 parts of a de-foaming agent, 2-6 parts of a pigment and 5-15 parts of a filler. The UV curing adhesive printing ink prepared by the invention is quick in curing speed, good in dispersibility, high in bonding strength, suitable for offset printing and free from solvent volatilization and pollution, conforms to the environmental protection requirements and is suitable for the printing fields of food and drug packaging and the like.

Description

technical field [0001] The invention relates to the field of inks, in particular to a UV curing 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. [0003] At present, the printing industry generally uses solvent-based inks for film printing production, but this type of ink contains a large amount of volatile organic solvents. When the volatilized gas enters the human body during use, it will cause serious damage to the liver and nervous system. cause great harm. [0004] Ultraviolet curing (UV) offset printing ink refers to the ink that uses ultraviolet light of different wavelengths and energies to form a film and dry the ink under ult...
