Technical Field

The invention relates to the technical field of new printing materials of cultural products and preparation thereof, in particular to a heat transfer printing flower film with a wear-resistant process. The invention also relates to the wear-resistant transfer printing film and a production process thereof.

Background

The heat transfer printing film is widely applied to the fields of solid glue, cosmetics, office stationery and the like. Specifically, the thermal transfer printing film is a special functional printing film which is provided with pictures and texts with adhesive, is separated from the carrier film together with the release layer under the combined action of heat and pressure, and is firmly transferred on the surface of a printing stock. The heat transfer film is generally composed of 3 to 5 layers. The three-layer heat transfer film consists of a substrate layer, a printing layer and an adhesive layer; the four-layer heat transfer printing film consists of a substrate layer, a release layer, a printing layer and an adhesive layer; the five-layer heat transfer printing film consists of a substrate layer, a release layer, a printing layer, an adhesive layer and a hot melt adhesive powder layer. Base layer: namely, the carrier coated by the release agent, the printing ink and the adhesive is required to have temperature resistance, pressure resistance and small tensile deformation. A release layer: the release agent is a coating of a release agent, can be kept in a solid state at normal temperature, can be melted at a certain temperature, has small adhesive force with a substrate layer, can be quickly separated from the substrate layer, and has no adhesive residues. The release agent is the key for completing the separation of the printing layer from the substrate layer and transferring the printing layer to the surface of the printing stock. It is required to have good abrasion resistance, to protect the color ink, to reduce the radiation intensity of ultraviolet rays, to reduce the invasion of adverse factors in the air to the ink, to prolong the service life of the ink, and to buffer the adhesion of the substrate film and the printed layer. Printing layer: this layer is essential to the aesthetic quality of the transferred article. With the progress of printing technology and the development of image processing technology, the printing layer has various colors and patterns. Particularly, the pictures and texts obtained by gravure printing can well embody fine pictures and texts, so that the packaging decoration effect is more perfect. Adhesive layer: its basic performance is that it has higher cohesive force with the surface of printing stock, and can ensure that the printing layer is firmly combined with surface of printing stock. The layer of adhesive must be compatible with the substrate. Different adhesives have a very different adhesion to the substrate due to the different chemical compositions. The selection should be made according to different substrates. When all the existing thermal transfer printing films are used, the defects of white spots, dirt, streaks and the like on the surfaces of printing stocks are ensured, otherwise, the performances of the whole printing films, such as aesthetic property, weather resistance, scratch resistance, thermal fracture property, overlapping property and the like, are influenced; in addition, the wear resistance of the heat transfer printing flower film determines the service life to a certain extent. Therefore, the heat transfer printing film of the wear-resistant process is developed, so that the attractiveness of the heat transfer printing film can be improved, the covering property on a substrate can be improved, and the product grade can be improved.
