Embodiment 1
[0038] Prepare the special anti-orange belt adhesive film for laser card through the following steps 1
[0039] Step (1) earlier with epoxy value 0.4, 30 parts of diphenol group propane epoxy resins of epoxy resin diphenol group propane epoxy resin of molecular weight 300, 20 parts of HEA of acrylate, 30 parts of BA and 10 parts of CAC of cosolvent Add to the container and stir evenly, then heat up to 110°C, add 1 part of triethylamine as catalyst, stir and react at 120 rpm for 6 hours, then cool down to 30°C, add 25 parts of diluent PMPTA, 20 parts of filler meteorological silica and initiator 1 part of 1173, stirred at 300 rpm for 0.5 hours to obtain the mirror layer material, and coated in two layers;
[0040]Step (2) Coating the first and second mirror layers on both sides of the substrate layer respectively, irradiating with ultraviolet light (UV) and heating and curing, and then coating an adhesive layer on the surface of any mirror layer and drying it to obtain a laser ...

Abstract
The invention relates to an anti-orange belt adhesive film special for a laser identification card and a preparation method and application thereof.The anti-orange belt adhesive film special for the laser identification card comprises a first mirror surface layer, a base material layer, a second mirror surface layer and a bonding layer which are sequentially overlapped, and the first mirror surface layer and the second mirror surface layer are the same in raw material component; the mirror surface layer is prepared from the following raw material components in parts by weight: 30 to 50 parts of epoxy resin, 30 to 50 parts of acrylic ester, 10 to 20 parts of cosolvent, 0.5 to 1.5 parts of catalyst, 5 to 25 parts of diluent, 10 to 20 parts of filler and 1 to 5 parts of initiator. The surface of the base material layer is coated with the mirror surface layer to prepare the orange-resistant belt adhesive film special for the laser card, high-temperature wriggling and deformation of molecules of the base material layer can be resisted in the high-temperature laminating card pressing process, the mirror surface state of the surface of the adhesive film is kept, the surface of the laser card prepared from the adhesive film is free of orange peel phenomenon, the laser effect is fully embodied and is not attenuated, and the service life of the laser card is prolonged. Not only is the attractiveness improved, but also the anti-counterfeiting property is ensured.
Description
technical field [0001] The invention belongs to the technical field of card manufacturing and relates to film modification, in particular to a special anti-orange belt adhesive film for laser card and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the appearance of various products no longer shows people the old appearance of simple patterns and rough production, but begins to pursue bright colors and metallic textures to improve and beautify the visual effect. Among them, the imitation metal appearance materials (commonly known as laser materials) with special effects such as rainbow, mirror surface and cat's eye produced by the combination of laser holography and metal evaporation technology are developing most rapidly. The card field has also begun to use a large number of laser materials to achieve the purpose of decorative appearance or anti-counterfeiting. Because the laser material uses the principle of ...
