AI Technical Summary

Problems solved by technology

One is that the wetting and dispersing performance of the pigment is poor, and it is easy to precipitate, stratify and agglomerate after adding the pearlescent pigment. This will not only cause serious color difference in the printed product during the production process, resulting in the scrap of the printed product, but also make it difficult to store the leftover pearlescent ink. Increase the production cost; second, the bonding adhesion is weak, not suitable for adding pearlescent pigments in a large proportion, otherwise powder removal will occur; third, the orientation of pearlescent pigments in the coating is poor, which seriously affects the pearlescent effect of printed products

Abstract

The invention discloses a gravure pearlescent ink compound for tipping paper and a preparation method thereof. The gravure pearlescent ink compound for tipping paper is prepared from the following rawmaterials by weight: 5-25 parts of polyvinyl butyral resin, 5-20 parts of cellulose acetate butyrate, 1-10 parts of aldehyde ketone resin, 1-10 parts of rosin glycerin ester, 1-10 parts of an antisettling agent, and 50-80 parts of a solvent. The gravure pearlescent ink compound provided by the invention adopts reasonable collocation of a variety of non-toxic and transparent resins in the formula,and is synthesized by a blending process. The ink compound has the characteristics of good gloss, excellent pearlescent pigment wet dispersion and directional arrangement properties, strong adhesion,good printing adaptability, fast drying, precipitation prevention, wide application range and the like.

Description

technical field [0001] The present invention relates to ink and varnish, more specifically to a gravure pearlescent varnish for tipping paper and a preparation method thereof. Background technique [0002] In recent years, with the sustained and steady growth of my country's national economy, a wider market space has been provided for the printing and packaging products industry. Among them, pearlescent printing is a special-effect printing product printed with special ink, and its market prospect is widely optimistic by the industry. Through the organic combination of people's personalized design and printing quality, pearlescent printing can rebuild a new color space and light and color effect on the surface of plain and simple paper and other substrates. Using lithographic printing, gravure printing, flexographic printing, letterpress printing, screen printing and other printing processes, in the outer packaging of high-end cosmetics, various cigarette packaging boxes, h...
