Solvent type gravure pearlescent ink and preparation method thereof

Abstract

The invention discloses solvent type gravure pearlescent ink, belonging to the field of ink. The solvent type gravure pearlescent ink comprises the following components in percentage by weight: 10%-20% of pearlescent pigments, 10%-20% of solid resin, 10%-20% of ethyl acetate, 10%-25% of ethanol, 5%-10% of isopropanol, 20%-25% of n-propyl acetate, 5%-10% of propanediol butyl ether and 0.1%-5% of a compound aid, wherein the compound aid is a mixture of a dispersing agent, a wetting agent, a color spreading agent and a flattening agent. The invention further discloses a preparation method of the solvent type gravure pearlescent ink. The preparation method comprises the following steps: preparation of resin liquid, dispersion of the pearlescent pigments, mixing, and sand grinding. By virtue of environment-friendly solvents, the solvent type gravure pearlescent ink is free of benzene and halogenated hydrocarbon, low in toxicity and small in smell; the volatilization velocity of the ink is controlled by virtue of volatilization gradients of the different solvents, and the ink presents the relatively good glossiness and pearlescent effect; the preparation method is simple and practical; the production cost is effectively lowered, the ink is stable in quality and has strong universality in the field of gravure printing; a printed product has a good surface effect.

AI Technical Summary

Benefits of technology

This new type of liquid has been developed from environmental-friendly chemical substances without harmful or bad smells like naptha oil. It achieves this by controlling how much it evaporates during use based on factors such as temperature, pressure, time, etc., resulting in an improved appearance for both paper documents and printings. Additionally, its cost savings make them more practical than traditional methods due to their high efficiency at producing special colors while also being able to produce clear prints even when applied over uneven surfaces.

Problems solved by technology

The technical problem addressed in this patents relates to finding a proper type for creation of strong yet nonvolatile cobalt oil (CoO) based toner that works well when used at different levels within specific ranges. This would help reduce environmental concerns associated with disposable products such as those containing Co0 because these types were found to cause pollution from waste material produced during production processes.
