Abstract

The invention provides an oil modified phenolic resin binder. Components of the binder comprise 30-50% of vegetable oil, 30-50% of phenolic resin and 5-40% of an organic solvent. The oil modified phenolic resin binder utilizes terminal hydroxymethyl with active group to perform Diels-Alder addition reaction with double bonds of alkylphenol oil-soluble phenolic resin and the vegetable oil. The oil modified phenolic resin binder can be obtained by processes including heating and cooling twice, insulating by adding the phenolic resin and cooling by adding the organic solvent. The oil modified phenolic resin binder enhances transparency of products by improving polymerization process, and ensures stable viscosity within shelf life and no thick skinning over on the surface of the binder.

Description

technical field [0001] The invention provides a binder for engraving gravure ink, that is, a linear-terminated methylol-p-alkyl phenolic resin binder modified by vegetable oil and a preparation process thereof, which belongs to the chemical industry field of organic synthesis. Background technique [0002] Phenolic resin binder is the reaction product of linear terminal methylol p-alkyl phenolic resin and vegetable oil, and it is a binder for engraving gravure ink. The ink made with it has the characteristics of fast fixing speed and good physical and chemical properties. [0003] During the production and use of this type of connecting material, there is a phenomenon that the produced connecting material product is transparent when it comes out of the kettle, and becomes cloudy after storage. [0004] Through the detection and analysis of imported phenolic resin binders and domestic (old technology) phenolic resin binders, it is found that imported binders have good stabil...
