Problems solved by technology

[0004] 1. The oil solubility, aliphatic hydrocarbon solubility and viscoelasticity of the product cannot be balanced: oil solubility and aliphatic hydrocarbon solubility are poor, the fixation time is long, and the gloss is low;
[0005] 2. The color of the product is darker: the use of conventional petroleum resin must be melted at a lower temperature, and the product is prone to high-temperature oxidation and discoloration, resulting in a darker color of the product, which cannot be applied to special inks such as white and yellow;
[0006] 3. The viscosity is not high enough

Abstract

The invention belongs to the field of ink binders and particularly relates to a high-gloss and high-viscosity resin binder and a preparation technology thereof. The high-gloss and high-viscosity resin binder is characterized by comprising components in parts by mass as follows: 20-25 parts of rosin modified phenolic resin, 20-25 parts of modified petroleum resin, 15-20 parts of linseed oil, 25-35 parts of ink oil and 0.8-1.2 parts of a peptizing agent. The resin binder not only is high in gloss, but also has the advantages of high viscosity, great molecular weight and high fixing speed of traditional resin, a prepared ink product has high reductibility on a printing dot, so that a printed product is high in clarity, and besides, the ink has higher printability.

Description

technical field [0001] The invention belongs to the field of ink binders, in particular to a high-gloss, high-viscosity resin binder and a preparation process thereof. Background technique [0002] Rosin-modified phenolic resin is one of the resins widely used in printing ink and paint manufacturing industries, especially the important resins for ink binders. Their quality directly determines the performance of inks, such as printability, drying performance, and film formation. performance etc. [0003] Ink products made of traditional rosin-modified phenolic resins have the following defects: [0004] 1. The oil solubility, aliphatic hydrocarbon solubility and viscoelasticity of the product cannot be balanced: oil solubility and aliphatic hydrocarbon solubility are poor, the fixation time is long, and the gloss is low; [0005] 2. The color of the product is darker: the use of conventional petroleum resin must be melted at a lower temperature, and the product is prone to ...
