Problems solved by technology

[0005] Water-based varnish has very good environmental protection performance, but it is easy to absorb moisture. Although oil-based varnish has a good waterproof effect, it is prone to sticking during cigarette rolling and storage in high-temperature environments, which seriously affects the quality of cigarettes. Production efficiency and quality
[0006] In order to solve the above problems, a Chinese patent with the application number CN201910658926.2 is disclosed in the prior art, an anti-shedding and anti-adhesion varnish for aluminum-plated tipping paper and its preparation method, and the raw materials used are calculated by parts by weight. Bottom: 30-70 parts of water-based film-forming resin, 5-20 parts of water-based non-film-forming resin, 1-10 parts of high-temperature resistant resin, 1-10 parts of water-based high-density polyethylene wax emulsion, 0.1-1 parts of water-based adhesion promoter , 0.1-0.5 parts of water-based defoaming agent, 15-50 parts of purified water, appropriate amount of PH regulator, not only contains adhesion promoter, but also adds temperature-resistant components, so as to ensure firm adhesion, stable size and high temperature resistance. The high-gloss transparent coating solves quality defects such as weak adhesion and easy peeling off of the varnish coating of aluminum-plated tipping paper, large variation coefficient of laser drilling, and adhesion, but it solves the problem of anti-adhesion of water-soluble varnish. Does not solve the problem of anti-blocking of oil-soluble varnish

Abstract

The invention discloses anti-adhesion gloss oil for tipping paper for cigarettes as well as a preparation method and application of the anti-adhesion gloss oil, and the anti-adhesion gloss oil comprises the following components in parts by mass: 40-60 parts of a solvent, 15-25 parts of modified nitrocotton, 10-20 parts of fat-soluble resin, 0.2-2 parts of wax powder, 1-4 parts of propylene glycol monoethyl ether and 2-5 parts of a water repellent agent. The fat-soluble gloss oil with the modified nitrocotton with the high glass transition temperature as the connecting material can improve the anti-adhesion performance of the tipping paper for the cigarettes, adhesion of the tipping paper for the cigarettes in the cigarette rolling and storing process can be effectively prevented, then the production efficiency and the product quality of the cigarettes are improved, the wax powder mainly plays a role in moistening and extinction, flow can be improved, a smooth surface is obtained, and the scratch resistance of the gloss oil is improved.

Description

technical field [0001] The invention relates to the field of varnish, in particular to an anti-adhesion varnish for cigarette tipping paper, a preparation method and application thereof. [0002] technical background [0003] Tipping paper, commonly known as "tipping paper", is mainly used for connecting filter tips and cigarettes. With the continuous improvement of people's living standards, as well as the transformation of consumption concepts and health awareness, the use of tipping paper is not only for packaging, but also for decoration. [0004] At present, the varnish used in the cigarette tipping paper industry is mostly water-based varnish, which is printed in the last color sequence, so it is also called varnish. The varnish is applied on the surface of the replica that has completed the graphic printing process. A solid printing plate or a graphic printing plate is printed with varnish once or twice by a printing machine to obtain a bright film layer on the surfac...
