Abstract

The invention relates to an aqueous touch gloss oil for gravure printing and a preparation method thereof. The aqueous touch gloss oil comprises the following components in parts by weight: 30 to 60 parts of film-forming resin, 30 to 60 parts of solvent, and 1 to 8 parts of auxiliary agent; wherein the film-forming resin is acrylic resin, the solvent is water or a mixture of water and alcohol, and the auxiliary agent is polyurethane emulsion. Compared with the prior art, the provided gloss oil belongs to aqueous resin, which has a good levelling property and film surface smoothness. The gloss oil can be well printed on the surface of various paper to protect the integrity and beautiful appearance of printed matters. The gloss oil has the advantages of beautiful appearance, stable performance, good scratch resistant performance, and good waterproof property. The film formed by the gloss oil is transparent, and thus the color and luster of medium can be more clearly displayed. The hand feeling is smooth. The preparation technology is simple, the finished product is stable, additive is not needed, the production cost is saved, and the gloss oil is suitable for industrial high-efficient massive production.

Description

technical field [0001] The invention belongs to the technical field of metallic inks, and in particular relates to a water-based tactile varnish for gravure printing and a preparation method thereof. Background technique [0002] Varnish is a product that has emerged with the rapid development of the packaging and printing industry. It is coated on the surface of the object by different printing processes to form a solid layer with firm adhesion, certain strength and continuity. The role of graphics, based on the above advantages, varnish is widely used on the outer surface of food and beverage, shoes and clothing, tobacco and alcohol packaging. [0003] As a kind of printing process, gravure printing occupies an extremely important position in the fields of printing, packaging and graphic publishing due to its advantages of bright colors, high saturation, stable quality and fast printing speed. [0004] Water-based varnish can basically meet the requirements of the packag...
