Abstract

The invention provides a binder and a preparation method thereof and belongs to the offset printing field. The binder comprises 40-50 parts of rosin modified octylphenol phenolic resin, 20-30 parts of linseed oil, 25-35 parts of mineral oil, 1-2 parts of resin oil, 0.1-0.3 part of tetradecyl alcohol and 0.1-1 part of auxiliaries. As the binder is added with the resin oil component, the mineral oil compatibility, the pigment wettability, the water resistance and the leveling property of the binder can be enhanced; besides, the rosin modified octylphenol phenolic resin is in partial addition reaction with the linseed oil at the temperature of 220-240 DEG C, so that the molecular crosslinking degree in the rosin modified octylphenol phenolic resin is increased; as a result, the viscosity of the binder can be improved. The viscosity of the binder provided by the invention is capable of reaching 40000-47000 mPa.S / 25 DEG C.

Description

technical field [0001] The invention relates to an ink binder and a preparation method thereof, belonging to the field of offset printing. Background technique [0002] With the prosperity of the packaging and printing market, high-grade offset printing inks have developed rapidly. [0003] Binder is a liquid substance made by miscible polymer substances, also known as varnish, vehicle or vehicle. It is the main component of ink and the carrier for dispersing pigments and fillers. The material can be transferred to the surface of the substrate through the printing machine to play the role of adjusting the gloss, abrasion resistance, rheology, viscosity and transfer performance of the ink; therefore, different types of binders can be prepared For inks, the properties of the binder often determine the performance of the ink. [0004] In the prior art, the binder is usually composed of resin, vegetable oil, mineral oil, organic solvent and other additives. For example, Chines...
