A kind of anti-shedding, anti-adhesion varnish for aluminized tipping paper and preparation method thereof

Abstract

The invention discloses an anti-shedding and anti-adhesion varnish for aluminum-plated tipping paper and a preparation method thereof. The ratio of the raw materials used is calculated in parts by weight as follows: 30-70 parts of water-based film-forming resin, and 30-70 parts of water-based non-film-forming resin 5-20 parts, high temperature resistant resin 1-10 parts, water-based high-density polyethylene wax emulsion 1-10 parts, water-based adhesion promoter 0.1-1 parts, water-based defoamer 0.1-0.5 parts, purified water 15-50 parts , appropriate amount of PH regulator. The varnish of the present invention not only contains an adhesion promoter, but also adds a temperature-resistant component, so as to ensure a high-gloss transparent coating with firm adhesion, stable size, and high temperature resistance, and solves the problem of aluminized tipping paper varnish. Quality defects such as poor adhesion of the coating and easy peeling off, large coefficient of variation of laser drilling, and adhesion. At the same time, the varnish layer also has the characteristics of wear resistance, strong roll resistance, environmental protection, simple preparation process, and convenient use.

Description

technical field [0001] The invention relates to a printing varnish, and more particularly to a varnish for aluminized tipping paper and a preparation method thereof. Background technique [0002] The tipping paper, commonly known as "tip paper", is mainly used for connecting the filter tip to the cigarette. With the continuous improvement of people's living standards and the change of consumption concept and health awareness, the use of tipping paper pays more attention to its decoration in addition to packaging. Among them, the aluminized tipping paper has a shiny metallic luster, giving people a strong visual impact, and at the same time taking into account the functions of packaging and decoration, so it has been favored by the market and consumers. [0003] The aluminized tipping paper is based on the transfer type bright silver tipping base paper as the printing substrate, that is, the vacuum-evaporated metal aluminum layer is transferred and compounded to the surface ...

AI Technical Summary

Problems solved by technology

In this way, the adhesion of the varnish coating is reduced, and quality defects such as shedding of the varnish coating and large coefficient of variation of laser drilling are prone to occur.

In addition, the small box packaging after the tipping paper is rolled into the cigarettes requires heat sealing of the cigarette film under high temperature conditions, while the metal aluminum contained in the aluminized type tipping paper has excellent thermal conductivity, and there are adjacent gaps in heat sealing under high temperature conditions.
