本实用新型提出一种烫印膜，该烫印膜的成像层不易老化或褪色，清晰度较高。The utility model provides a hot stamping film, the imaging layer of the hot stamping film is not easy to age or fade, and has high definition.
在本实用新型实施例中，如图1所示，该烫印膜10包括依次层叠设置的薄膜层110、离型层120、成像层130、反光层140、背胶层150以及透明的耐磨层160，其中，耐磨层160层叠设置在成像层130与所述离型层120之间。In the embodiment of the present utility model, as shown in FIG. 1, the hot stamping film 10 includes a film layer 110, a release layer 120, an imaging layer 130, a reflective layer 140, an adhesive layer 150 and a transparent wear-resistant layer 160 , wherein the wear-resistant layer 160 is stacked between the imaging layer 130 and the release layer 120 .
具体地，薄膜层110是PET薄膜，PET薄膜是以聚对苯二甲酸乙二醇酯为原料，采用挤出法制成厚片，再经双向拉伸制成的薄膜材料，其具有良好的透明性和气密性，此处需要说明的是，薄膜层110中薄的定义是指薄膜层110的厚度与薄膜层110的面积相比较时，薄膜层110的厚度值较小，能够让成像层的图案无阻碍地展示；离型层120是由是离型剂所形成的，用于防止成型的薄膜层110与成像层130相互粘接，按照离型剂的不同状态，离型层120可以为薄膜、膏状或蜡状；成像层130上设置有图案，该图案可以为装饰图案、或用于防伪的防伪标识；反光层140用于将光线进行反射至成像层130，使得成像层130的色彩更加绚丽；背胶层150是由压敏胶或热熔胶所形成的，用于将烫印膜10粘接固定于待印制品的表面。Specifically, the film layer 110 is a PET film. The PET film is made of polyethylene terephthalate as a raw material, which is made into a thick sheet by extrusion and then biaxially stretched. It has good transparency. It needs to be explained here that the definition of thin in the film layer 110 means that when the thickness of the film layer 110 is compared with the area of the film layer 110, the thickness value of the film layer 110 is smaller, which can make the imaging layer The pattern is displayed unhindered; the release layer 120 is formed by a release agent, and is used to prevent the formed film layer 110 and the imaging layer 130 from adhering to each other. According to the different states of the release agent, the release layer 120 can be film, paste or wax; the imaging layer 130 is provided with a pattern, which can be a decorative pattern or an anti-counterfeiting mark for anti-counterfeiting; the reflective layer 140 is used to reflect light to the imaging layer 130, so that the imaging layer 130 The color is more brilliant; the adhesive layer 150 is formed by pressure-sensitive adhesive or hot-melt adhesive, and is used to bond and fix the hot stamping film 10 on the surface of the product to be printed.
本实用新型的技术方案通过采用在成像层130与离型层120之间设置透明的耐磨层160，并将耐磨层160粘接固定在成像层130面对所述离型层120的层面上，从而通过该耐磨层160实现对成像层130的防护，避免了成像层130被刮花或磨损掉色，使得成像层130的图案能够保持完整以及高的清晰度，最终提高烫印膜10的显示效果。The technical scheme of the utility model adopts a transparent wear-resistant layer 160 between the imaging layer 130 and the release layer 120, and the wear-resistant layer 160 is bonded and fixed on the layer of the imaging layer 130 facing the release layer 120. , so that the protection of the imaging layer 130 is achieved through the wear-resistant layer 160, which prevents the imaging layer 130 from being scratched or worn out, so that the pattern of the imaging layer 130 can maintain integrity and high definition, and finally improve the hot stamping film 10. display effect.
进一步地，在本实用新型上述实施例中，该耐磨层160为丙烯酸清漆层和/或有机硅清漆层。其中，丙烯酸清漆的主要成分是丙烯酸树脂、体质颜料、助剂和有机溶剂等，丙烯酸清漆可常温干燥，具有良好的耐候性、耐光性、耐热性、防霉性及附着力，因此，耐磨层160通常由丙烯酸清漆制成。在此需要说明的是，丙烯酸清漆层不仅具有良好的耐磨性能，还具有良好的耐温、耐候性，因此，本实用新型通过在成像层130与所述离型层120之间设置耐磨层160，使得撕下薄膜层110和离型层120后，耐磨层160粘接固定在成像层130面向离型层120的层面上，进而通过丙烯酸清漆材质的耐磨层160对成像层130起到耐温和耐磨的双重防护作用。Further, in the above embodiments of the present utility model, the wear-resistant layer 160 is an acrylic varnish layer and/or a silicone varnish layer. Among them, the main components of acrylic varnish are acrylic resin, extender pigment, additives and organic solvents, etc. Acrylic varnish can be dried at room temperature, and has good weather resistance, light resistance, heat resistance, mildew resistance and adhesion. Abrasive layer 160 is typically made of acrylic varnish. It should be noted here that the acrylic varnish layer not only has good wear resistance, but also has good temperature resistance and weather resistance. layer 160, so that after tearing off the film layer 110 and the release layer 120, the wear-resistant layer 160 is bonded and fixed on the layer of the imaging layer 130 facing the release layer 120, and then the wear-resistant layer 160 of the acrylic varnish material is applied to the imaging layer 130 Play a double protective role of temperature and wear resistance.
具体地，所述耐磨层160由空气喷涂工艺或光固化工艺粘接固定在所述成像层130的层面，由于丙烯酸清漆和有机硅清漆的初始状态均为液态，为了将液态的耐磨层160均匀地涂覆在成像层130与离型层120之间，通常采用的做法是通过空气喷涂工艺涂覆耐腐蚀层160。空气喷涂工艺的具体工作原理是：利用压缩空气的气流，流过喷枪喷嘴孔形成负压，负压使丙烯酸清漆或有机硅清漆从吸管吸入，经喷嘴喷出，进而形成漆雾，该漆雾喷射到成像层130表面上形成均匀的耐磨层160。Specifically, the wear-resistant layer 160 is bonded and fixed on the layer of the imaging layer 130 by an air spraying process or a photocuring process. Since the initial states of the acrylic varnish and the silicone varnish are both liquid, in order to make the liquid wear-resistant layer 160 is uniformly coated between the imaging layer 130 and the release layer 120 , and the common practice is to coat the corrosion-resistant layer 160 by air spraying process. The specific working principle of the air spraying process is: use the airflow of compressed air to flow through the nozzle hole of the spray gun to form a negative pressure, and the negative pressure makes the acrylic varnish or silicone varnish sucked in from the straw and sprayed out through the nozzle to form a paint mist. Spraying onto the surface of the imaging layer 130 forms a uniform wear layer 160 .
一般地，耐磨层160的厚度与耐受的磨损量成正比，然而，耐磨层160越厚，烫印膜10的成本越高、显示效果越差，因此，本实用新型在综合考虑了烫印膜10的耐磨效果和显示效果后，将烫印膜10耐磨层160的厚度设置在2μm至10μm的范围内，如此，既能满足烫印膜10较佳的耐磨效果，又能保证烫印膜10清晰地显示成像层130的图案。Generally, the thickness of the wear-resistant layer 160 is directly proportional to the wear resistance. However, the thicker the wear-resistant layer 160, the higher the cost of the hot stamping film 10 and the worse the display effect. Therefore, the utility model comprehensively considers After the wear-resistant effect and display effect of the hot stamping film 10, the thickness of the wear-resistant layer 160 of the hot stamping film 10 is set in the range of 2 μm to 10 μm. It can ensure that the hot stamping film 10 clearly displays the pattern of the imaging layer 130 .
在本实用新型另一实施例中，请继续参照图1，为了进一步提高烫印膜10的耐磨能力，该耐磨层160背对成像层130的层面上磁控溅射有纳米金属层，该纳米金属层的厚度为0.5至4μm，且纳米金属层的厚度呈均匀设置。纳米金属层具有较高的硬度，能够大幅提高烫印膜10表面的耐磨能力，避免成像层130被刮花。然本专利的设计不限于此，于其他实施例中，还可以在耐磨层160的表面设置高分子树脂层以进一步地提高烫印膜10表面的耐磨能力。In another embodiment of the present utility model, please continue to refer to FIG. 1, in order to further improve the wear resistance of the hot stamping film 10, the wear-resistant layer 160 is magnetron sputtered with a nano-metal layer on the layer facing away from the imaging layer 130, The thickness of the nano metal layer is 0.5 to 4 μm, and the thickness of the nano metal layer is set uniformly. The nano-metal layer has relatively high hardness, which can greatly improve the wear resistance of the surface of the hot stamping film 10 and prevent the imaging layer 130 from being scratched. However, the design of this patent is not limited thereto. In other embodiments, a polymer resin layer can also be provided on the surface of the wear-resistant layer 160 to further improve the wear-resistant ability of the surface of the hot stamping film 10 .
为了增强成像层130与反光层140之间的固定强度，本实用新型上述实施例中的成像层130由树脂材料UV固化制成或模压制成。所谓UV固化是指紫外线光固化工艺，模压工艺是指通过加热、加压固定成像层。其中，紫外线光固化工艺可以将成像层130粘接固定在反光层140上，模压工艺可进一步减小成像层130与反光层140之间的间隙，进而提高成像层130的固定强度。In order to enhance the fixation strength between the imaging layer 130 and the reflective layer 140, the imaging layer 130 in the above embodiments of the present invention is made of resin material UV cured or molded. The so-called UV curing refers to the ultraviolet light curing process, and the molding process refers to fixing the imaging layer by heating and pressing. Wherein, the ultraviolet light curing process can bond and fix the imaging layer 130 on the reflective layer 140 , and the molding process can further reduce the gap between the imaging layer 130 and the reflective layer 140 , thereby improving the fixing strength of the imaging layer 130 .
请参照图2，为了使得本实用新型提出的烫印膜10具备防伪能力，在本实用新型再一实施例中，成像层130背对离型层120的层面上设有激光防伪图案170，该激光防伪图案170能够使得成像层130的显示效果复杂多变，进而提高成像层130的防伪效果。Please refer to Fig. 2, in order to make the hot stamping film 10 proposed by the utility model have anti-counterfeiting capabilities, in another embodiment of the utility model, a laser anti-counterfeiting pattern 170 is provided on the layer of the imaging layer 130 facing away from the release layer 120. The laser anti-counterfeiting pattern 170 can make the display effect of the imaging layer 130 complex and changeable, thereby improving the anti-counterfeiting effect of the imaging layer 130 .
烫印膜10最终需要将薄膜层110撕除，离型层120的作用是便于薄膜层110与成像层130的脱离，因此，离型层120的离型剂可以为OP蜡、OPE蜡或蒙旦蜡中的一种或多种。其中，OP蜡离型剂价格便宜、使用方便、无毒、脱模效果好，因此，在本实施例中，该离型层120所采用的离型剂优选为OP蜡。反光层140的作用是将光线反射至成像层130，使得成像层130的色彩更加绚丽，因此，反光层140可以为镀铝层和/或硫化锌荧光层。The hot stamping film 10 finally needs to tear off the film layer 110, and the effect of the release layer 120 is to facilitate the separation of the film layer 110 and the imaging layer 130. Therefore, the release agent of the release layer 120 can be OP wax, OPE wax or Mongolian wax. One or more of denier waxes. Among them, the OP wax release agent is cheap, easy to use, non-toxic, and has good mold release effect. Therefore, in this embodiment, the release agent used in the release layer 120 is preferably OP wax. The function of the reflective layer 140 is to reflect light to the imaging layer 130, so that the color of the imaging layer 130 is more brilliant, therefore, the reflective layer 140 can be an aluminum layer and/or a zinc sulfide fluorescent layer.
以上所述仅为本实用新型的优选实施例，并非因此限制本实用新型的专利范围，凡是在本实用新型的发明构思下，利用本实用新型说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本实用新型的专利保护范围内。The above is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model.
