Water-based matte pigment transfer printing film and preparation method thereof

Abstract

The invention discloses a water-based matte pigment transfer printing film and a preparation method thereof. The water-based matte pigment transfer printing film comprises a layer of PET base film (1), wherein the PET base film is sequentially covered by a water-based matte primer coating agent (2), and the water-based matte primer coating agent is prepared by mixing water-base resin with high-strength adhesion to the PET base film, inorganic filler, a waterborne curing agent, a waterborne aid and water; the surface of the primer coating agent is at least covered by a layer of water-based matte type release agent (3); then the surface of the release agent is at least covered by a layer of water-based coloring adhesive layer (4); the water-based coloring adhesive layer is prepared from waterborne pigment color paste, water-based hot melt adhesive, waterborne aid and water according to a certain proportion, and the materials are ground, mixed, wetted and dispersed to be prepared into thewater-based coloring adhesive layer; the coating is that the materials sequentially cover the PET base film in a scraper anilox roller coating mode and are dried by a 80 to 170 DEG C drying tunnel. The prepared hot stamping film has the advantages of good matte effect, strong coloring hiding power, multiple color kinds, good flexibility, strong base material adhesion, suitability for continuous hot stamping and the like. As the water-based raw materials are utilized, no volatile organic matter is generated in a production process, VOCs residues in products are avoided, and good environmental,safe and healthy effects are achieved.

Description

technical field [0001] The invention relates to a water-based matte pigment transfer film for hot stamping on various substrates and a manufacturing method thereof, belonging to the technical field of hot stamping. Background technique [0002] Transfer printing (hot stamping) is a special printing technology. The transfer (hot stamping) film can replace the ink. When using it, the hot stamping film (anodized aluminum) is transferred to the substrate to be hot stamped according to the image and text of the hot stamping template. The surface of the material can be applied to various paper products (including various types of paper and cardboard that have been printed or not printed and coated, and various types of coated paper), various types of plastics, various types of leather and wood and other materials. Because it is a clean and pollution-free process, it is considered a green printing method internationally, and it is increasingly replacing some traditional printing me...

Problems solved by technology

Since the manufacture of this type of product requires repeated coating on the same base film, many coating materials are used. These raw materials containing a large amount of organic solvents used in the production process cause serious pollution to the environment. At the same time, these raw materials It is also a flammable and explosive dangerous chemical, which has potential safety hazards

On the other hand, in terms of the quality of the products produced, the matte film produced also has obvious defects: after the matte film is hot stamped, due to the effect of pressure and temperature, the pattern surface after peeling is matte. The effect is not enough, the appearance of the formed text pattern is not delicate, which affects the unique effect of matte, and the transfer film is not flexible enough, easy to "fly gold", poor adhesion to the substrate, more solvent residue, inconvenient use and other defects
