Description

Anti-drop and anti-adhesion gloss oil for aluminized tipping paper and preparation method thereof
Technical Field
The invention relates to printing gloss oil, in particular to gloss oil for aluminized tipping paper and a preparation method thereof.
Background
The tipping paper is commonly called 'tipping paper', and is mainly used for rolling and connecting the filter tip and the cigarette. With the continuous improvement of the living standard of people and the transformation of consumption idea and health consciousness, the use of the tipping paper focuses more on the decoration of the tipping paper besides the packaging. The aluminum-plated tipping paper has flashing metallic luster, gives people strong visual impact, and simultaneously gives consideration to the functions of packaging and decoration, thereby being popular with the market and consumers.
The aluminized tipping paper is prepared by taking transfer type bright silver tipping base paper as a printing base material, namely transferring and compounding a metal aluminum layer subjected to vacuum evaporation onto the surface of the tipping white base paper by a transfer method, and performing subsequent processing such as transparent ink printing, varnish application, laser punching and the like by taking the metal aluminum layer as a printing surface. The varnishing is a method for obtaining a bright film layer on the surface of a printed matter by printing once or twice gloss oil on the surface of a duplicate which is completely finished with an image-text printing process by using a solid printing plate or an image-text printing plate and a printing machine. The printing glazing can enhance the light resistance of the printing ink, increase the heat and moisture resistance of the printing ink layer, and play a role in protecting prints and beautifying products. The glazing oil comprises water glazing oil, oily glazing oil, UV glazing oil, alcohol-soluble glazing oil and the like. At present, the most domestic application is the water-based varnish, and the water-based varnish has very good environmental protection performance.
At present, 30% of the drying process of the water-based gloss oil is realized by evaporation, 70% of the drying process is realized by material permeation and absorption, the drying speed is higher, and a film can be formed when the gloss oil contains 20% -30% of water. However, the aluminized tipping paper is essentially different from the general paper-based tipping paper in that the aluminized tipping paper uses a non-absorbent aluminized layer as a printing surface. Therefore, the adhesion of the gloss oil coating is reduced, and the quality defects of the gloss oil coating such as falling off, large variation coefficient of laser drilling and the like are easy to occur. In addition, the tipping paper is wrapped in a small box after being spliced with cigarettes, the cigarette film needs to be subjected to heat sealing under a high-temperature condition, the aluminized tipping paper contains metal aluminum with excellent heat conductivity, and the heat sealing under the high-temperature condition has the quality hidden trouble that adjacent cigarettes are adhered together. Therefore, the gloss oil for aluminum-plated tipping paper is required to have higher temperature resistance.
