Abstract

The invention relates to the technical field of printing ink, and in particular relates to gravure freezing point snowflake ink and a preparation method thereof. The gravure freezing point snowflake ink comprises acrylic resin, tetra-n-butyl titanate, an organic solvent, deionized water, a catalyst and a light initiator. The preparation method of the gravure freezing point snowflake ink comprises the following steps: step one, adding tetra-n-butyl titanate, the organic solvent and the catalyst into a reaction kettle, heating, and slowly adding deionized water into the reaction kettle for hydrolysis reaction to obtain hydrolysate; step two, adding the acrylic resin into the hydrolysate, and after raising the temperature, carrying out polycondensation reaction to obtain condensation polymer; step three, adding the light initiator into the condensation polymer, and stirring evenly to prepare the gravure freezing point snowflake ink. The gravure freezing point snowflake ink has the advantages of high glossiness, moderate viscosity, and good adhesion and friction resistance, so that printed matter is not easy to wear or scratch in the process of production and use, and the market competitiveness of the printed matter is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to a gravure freezing point snowflake ink and a preparation method thereof. Background technique [0002] Freezing point snowflake ink printing on the printed matter can make the surface present a layer of thin snow or ice brick effect, which is commonly known in the industry as "snowflake" (larger pattern, generally larger than 2mm) or "freezing point" (smaller pattern, The general pattern is less than 2mm). Freezing point snowflake ink is widely used in the printing of cigarette packs, wine boxes, gift boxes and other fine prints. [0003] The freezing point snowflake ink in the prior art has the following defects: (1) the glossiness of the printed matter after printing is not ideal, which reduces the market competitiveness of the printed matter; (2) the viscosity of the freezing point snowflake ink in the prior art is high, As a result, the printing ink layer is thick and...
