Research of the Factor that Influence the Glossiness of Water-based Tipping Paper Gravure Varnish

摘要

In order to prepare high-gloss water-soluble gravure varnish which is used on tipping paper,different content and types of filming resin with different content of all kinds of additives added are used to prepare water-soluble gravure varnish.Test its main performance and then use IGT apparatus to proof.The effect of varnish component and content on glossiness of water-soluble varnish is discussed by measuring glossiness of proof.The results show:different content and types of water-soluble filming resin have a great influence on the glossiness of water-soluble gravure varnish which is used on tipping paper; the glossiness of water-soluble varnish film can improve by adding auxiliaries such as cosolvent,substrate wetting agent,flow agent,wax emulsion and other promoter into water-soluble varnish system.
