Description

Crystal mark Technical Field The utility model relates to the technical field of labels, in particular to a crystal label. Background The crystal label is a decorative label, has the characteristics of high transparency, high glossiness and strong adhesiveness, and is widely applied to the fields of electronic products, home decoration, advertising and the like. However, most of the crystal labels on the market are made of pressure-sensitive adhesive, printed with patterns by a 3D printer, cured by UV, and transferred to a to-be-attached object, and only can be attached to smooth-surface materials such as metal, ceramic, plastic and the like, and the crystal labels have certain limitations, and rough surfaces such as cloth, leather and the like cannot be attached. Disclosure of utility model In order to solve the technical problems, the utility model provides the crystal mark which can be blanched on rough surfaces such as cloth, leather and the like, thereby meeting the decoration requirements of materials such as clothing, shoe bags and the like. The utility model aims at realizing the following technical scheme: The utility model provides a quartzy mark, including B membrane and the A membrane that sets gradually, B membrane including epoxy primer, transparent TPU rete and the waterborne primer that sets gradually, A membrane including polyurethane adhesive layer and the heavy type PET that sets gradually from the type rete that leaves, the waterborne primer set up in the top on polyurethane adhesive layer. Further, a UV ink pattern layer is arranged between the water-based primer layer and the polyurethane adhesive layer. The UV printing ink pattern layer is formed by printing by a 3D UV printer, particularly UV printing ink, UV is cured to obtain a UV printing ink pattern, the pattern is smooth and bright, the UV printing ink pattern is a 3D three-dimensional pattern, a good decorative anti-counterfeiting effect is achieved, and the UV printing ink pattern layer can be smoothly peeled off from the B film after being transferred to clothes. Further, the thickness of the epoxy resin primer layer is 1-2 mu m. The epoxy resin primer layer is specifically an epoxy resin primer layer, can greatly improve the binding force with polyurethane resin (polyurethane adhesive layer), can be tightly combined with overflowed hot melt adhesive (polyurethane adhesive layer) during blanching, meets the requirement of waste film discharge, ensures that the overflowed hot melt adhesive at the edge of a pattern can be smoothly taken away after secondary blanching, and can also take away the residual hot melt adhesive during transfer of part of the film B. Further, the thickness of the transparent TPU film layer is 50-100 mu m. The transparent TPU film layer (TPU: thermoplastic polyurethane elastomer) has excellent mechanical property, excellent high temperature resistance (80-120 ℃) and environmental protection safety, can well meet the hot stamping requirement, plays a role of a carrier film and a transfer film, and has soft characteristic that the B film can be well attached when being attached to the UV ink pattern layer, so that waste molten rubber except the UV ink pattern cover is discharged and taken away when being stripped. Further, the thickness of the transparent TPU film layer is 75 mu m. Further, the thickness of the aqueous primer layer is 1-2 μm. The water-based primer layer is an acrylic water-based primer layer, the surface energy of the transparent TPU film layer can be well improved, the redundant hot melt adhesive (polyurethane adhesive layer) at the uncovered part of the UV ink pattern layer can be well attached to the transparent TPU film layer, and the redundant hot melt adhesive tape can be removed when the pattern is attached to clothing in a transfer mode and peeled off, so that the requirement that the redundant adhesive is taken away by the transfer film is met.
