[ detailed description ] embodiments

The following examples are further to explain and supplement the present invention, and do not constitute any limitation to the present invention.

As shown in fig. 1 and fig. 2, the digital printing and lettering film of silica gel of the present invention comprises a release film 10, a reverse texture structure layer 20, a positive texture structure layer 30, a transparent PU silicone rubber layer 40, an ink adsorption layer 50, a pattern layer 60, a substrate layer 70 and a hot melt adhesive layer 80, which are sequentially compounded.

Wherein, the release film 10 is torn from the product when being used for thermal transfer printing. The release film 10 can be a PET film. In order to facilitate production and processing, an anti-sticking release agent is coated on the surface of the release film 10, namely, the surface of one side of the release film 10, which deviates from the reverse texture structure layer 20. The anti-sticking release agent can avoid the adhesion of the surface of the release film 10 and a production table surface together, so that the release film 10 is continuously conveyed during production conveniently, and the roll production of products is ensured.

The reverse texture structure layer 20 is used for forming required positive textures 31, one side surface of the reverse texture structure layer is combined with the release film 10, and the other side of the reverse texture structure layer is provided with reverse textures 21 with three-dimensional textures. The reverse grain 21 and the positive grain 31 are matched structures, and the positive grain 31 can be processed through the reverse grain 21. For example, the inverse 21 of the half-convex dot is a semicircular groove.

The positive texture structure layer 30 is provided with positive textures 31, and the positive textures 31 are matched with the negative textures 21, so that a mosaic structure is formed. The positive texture structure layer 30 is a transparent silica gel layer, and is formed by filling silica gel material in the reverse texture 21 of the reverse texture structure layer 20, and performing leveling and curing. The surface of the side, opposite to the positive texture 31, of the positive texture structure layer 30 is a plane, so that the transparent PU silicone rubber layer 40 is conveniently arranged. Further, in order to improve the adhesion between the films, the surface of the positive texture structure layer 30 opposite to the positive texture 31 may be subjected to plasma treatment or corona treatment to improve the roughness of the surface, which is beneficial to the adhesion of other material layers.

The bonding force between the positive grains 31 and the negative grains 21 is smaller than the bonding force between the release film 10 and the negative grain 21 structure, and when the release film 10 is torn, the positive grain structure layer 30 and the negative grain structure layer 20 can be separated from the bonding position between the positive grains 31 and the negative grains 21, so that the positive grains 31 on the positive grain structure layer 30 can be exposed by removing the release film 10 and the negative grain structure layer 20.

The transparent PU silicone rubber layer 40 is used for enhancing the adhesive force between the film layers and is transparent.

The ink adsorption layer 50 is used for improving the adhesive force of the ink so as to facilitate digital printing and print out colorful patterns. The ink adsorption layer 50 may be made of a material having a strong adsorption force to the water-based ink. The ink absorption layer 50 is transparent.

The pattern layer 60 is formed by digital printing on the ink absorption layer 50. The pattern in the pattern layer 60 is a plane pattern, which is set according to the positive texture 31, and can be a line pattern or a color block pattern; it may be a single color pattern or a multi-color pattern. After the thermal transfer printing, the three-dimensional positive texture 31 is in front, and a plane pattern on the rear side can be seen through the three-dimensional positive texture 31; the combination of the flat pattern and the positive texture 31 can form the visual effect of the three-dimensional pattern. In this embodiment, the pattern layer 60 is formed by performing digital printing with water-based ink, and the pattern layer 60 can be formed by performing printing on the ink absorption layer 50 with a conventional digital printer.

The substrate layer 70 serves as a substrate for the pattern layer 60 to make the pattern or color of the pattern layer 60 more desirable and to facilitate thermal transfer. Preferably, the substrate layer 70 is a white structural layer. In this embodiment, the backing layer 70 is formed by digital printing on the patterned layer 60. Preferably, the backing layer 70 may be formed by digitally printing with white water-based ink.

The hot melt adhesive layer 80 is used for adhering the lettering film to the surface of a printing stock during thermal transfer printing, so that the lettering film is firmly combined with the surface of the printing stock. The hot melt adhesive layer 80 has an adhesive function, and is formed by drying and cooling the hot melt adhesive powder scattered on the substrate layer 70. The thickness of the hot melt adhesive layer 80 can be set as desired. Because the substrate layer 70 is formed by printing with water-based ink, after the printing is finished, the substrate layer 70 has certain humidity, and hot-melt adhesive powder is scattered on the substrate layer 70 for drying, so that moisture can be absorbed, and the ink is not easy to be tinged to form a better pattern effect.

From this, just formed the utility model discloses a digital printing of silica gel membrane of carving characters, wherein, positive line structural layer 30, transparent PU silastic-layer 40, printing ink adsorbed layer 50 are the transparent structure layer, and pattern layer 60 is equipped with the pattern and for the nontransparent layer. When in use, the hot melt adhesive layer 80 of the lettering film is subjected to thermal transfer printing towards a printing stock, so that the hot melt adhesive is melted and adhered to the printing stock; subsequently, the release film 10 is removed, so that the reverse-grain structure layer 20 can be torn off, thereby exposing the positive grains 31 of the positive-grain structure layer 30. The regular veins 31 of the three-dimensional structure are matched with the plane pattern at the rear part of the regular veins, so that the effect of the three-dimensional pattern can be presented to the user.

3. filling a transparent silica gel material on the continuously walking material layer, and scraping the material to ensure that the silica gel material is filled in the reverse grains 21 of the reverse grain structure layer 20; after the silica gel material is solidified, a positive texture structure layer 30 with positive textures 31 can be formed on the negative texture structure layer 20;
