Abstract

The invention discloses thermoplasticity mixed alkylphenol phenolic resin for printing ink and a preparation method thereof. The preparation method comprises the following steps: more than two mixed alkylphenol react with aldehyde under the action of acidic catalyst to obtain thermoplasticity mixed alkylphenol phenolic resin for printing ink; the mixed alkylphenol is the mixture of two or more than two alkylphenol with alkyl group being C1-C30 or vegetable oil phenol. The invention takes account of resin dissolubility and solvent release property; a binder synthesized by the resin has the advantages of favourable storage stability, light color, moderate fixation time and the like; the prepared prinking ink has favourable printability, drying property, film-forming property and materialization resistance.

Description

technical field [0001] The invention relates to a thermoplastic phenolic resin prepared from various alkylphenols, in particular to a thermoplastic mixed alkylphenol phenolic resin for ink. Background technique [0002] There are two main types of phenolic resins used in the ink industry: one is rosin-modified phenolic resins, which are widely used in glue and printing inks; the other is oil-soluble alkylphenol pure phenolic resins. Resinoids include two types, RESOLE type (thermosetting) and NOVOLAC type (thermoplastic). [0003] Oil-soluble alkylphenol pure phenolic resin is superior to rosin-modified phenolic resin in terms of chemical resistance, yellowing resistance, and weather resistance. NOVOLAC type (thermoplastic) phenolic resin has no methylol group on the terminal group. It is generally considered to be soluble in dry oil without reaction. It is used in gravure ink to improve the physical and chemical resistance of printed matter such as alkali resistance, soap ...
