Abstract

The invention discloses environment-friendly waterless offset ink which comprises the following raw materials in parts by weight: 40-50 parts of polymerized rosin resin, 5-15 parts of an adhesive, 10-25 parts of refined linseed oil, 6-15 parts of a photoinitiator, 10-15 parts of phthalocyanine blue, 0.5-5 parts of an antiwear agent, 1-3 parts of a neutralizing agent and 0.1-2 parts of an addition agent, wherein the photoinitiator is one or a mixture of several of a cracking type initiator 907, BP (benzophenone) and triaryl iodonium salt, is one of important components of a photocuring adhesive, and plays a decisive role in the curing speed. The obtained ink is good in resin rheological property; a connecting material is higher in cohesive energy; the obtained ink is good in flowing property; the curing speed is not less than 10 m / min; and the ink is good in printing quality, clean and pollution-free.

Description

technical field [0001] The invention relates to a printing ink, in particular to an environment-friendly waterless offset printing ink. Background technique [0002] The composition of waterless offset printing ink is similar to that of general offset printing ink. It is composed of pigments, resin binders, solvents, diluents, and additives. Commonly used resins are rosin-modified phenolic resins, gelatinized rosin-modified phenolic resins and The main body is linseed oil and other vegetable oil-modified narcotic acid resins. Since there is no cooling of the fountain solution in the waterless offset printing process, the ink printing process is relatively sensitive to temperature, so there are special requirements for rheological properties of the resins that make up the ink. The general requirement is that the viscoelasticity of ordinary offset printing inks should be higher, and the shape should be slightly softer, that is to say, the fluidity should be better. In additi...
