Description
Technical Field
The invention relates to the field of security certificate cards, in particular to a manufacturing method and a structure of a security certificate card.
Background
At present, with the improvement of living standard of people, the social requirement on the optical anti-counterfeiting decoration of the card is continuously improved, and the demand of small-batch and customized production mode is increased. Meanwhile, in view of the comprehensive popularization of the use of the radio frequency chip in the field of the identification card, a novel identification card manufacturing method is needed to be found, so that the reading of the chip in the card is not influenced by the reflection layer of the identification card on the premise of meeting the anti-counterfeiting function, and the small-batch and customized production mode of the identification card is met.
In the prior art, the most important step of the card manufacturing process is the manufacturing of an anti-counterfeiting film, and the current card anti-counterfeiting film manufacturing processes mainly comprise the following steps: embedded, Overlay and Patch laser card base and the like. The embedded process is suitable for manufacturing local anti-counterfeiting patterns, protects key information and has high safety, but the reflection layer of the embedded process is transparent, so that the light transmittance of the certificate card base film is low, the brightness of the personalized information and the micro-nano structure information patterns of the certificate card is reduced, and the anti-counterfeiting identification performance and the attractiveness of the certificate card are further influenced. Both the Overlay and the Patch laser card base process can manufacture whole card anti-counterfeiting patterns, wherein the Patch laser card base material has a strong brightness effect, but the card with the whole laser aluminized film has a large signal shielding effect, the card reading distance and the card reading effect in actual operation are influenced, and meanwhile, the card body surface layers of the Overlay and the Patch laser card base two kinds of card manufacturing processes all adopt an adhesive processing mode, so that the anti-attack capability of the card body is reduced. Moreover, the card is generally manufactured in an embedded processing mode, and the embedded safety card with a high-light-transmittance reflecting layer is difficult to manufacture at present, mainly because a nano-structure information graph is easily damaged at high temperature and high pressure in the card manufacturing process. (PVC, PETG, the card lamination temperature of the material is 120-150 ℃, the card lamination temperature of the PC material is 150-180 ℃, and the use pressure is 5-20 MPa.) in the field of cards taking plastics as main materials, the sewage discharge also has requirements, the acid washing or alkali washing process can cause pollution to the environment, and particularly, the method such as changing the process and the like is needed to meet higher environmental protection requirements.
Based on the current situation, a new identification card manufacturing method is required to be developed at present so as to ensure that the identification card not only has a strong brightness and light transmission effect, but also does not influence the normal reading of an identification card chip, and simultaneously meets the requirements of environmental protection and beauty.

The release layer has the function of ensuring that the information layer with the micro-nano optical structure can be easily separated from the plastic film during transfer without adhesion and the like. The plastic film is required to have good cutting performance and proper fastness, the preferable thickness range is between 0.1 and 1um, and the plastic film can be arranged on the plastic base film in a coating mode.
Step S120, arranging a micro-nano optical structure pattern on the release layer 2 to form an information layer 3; the pattern of the micro-nano optical structure is a key element of certificate optical anti-counterfeiting, and the pattern presents grating stripes with different widths and directions on a microscopic level. The stripes generate different colors and motion effects under the optical action of reflection or diffraction, so that the aim of optical anti-counterfeiting is fulfilled. The copying and printing of the micro-nano optical structure can be realized through a hot pressing or UV transfer process. The appearance contour of the pattern depends on the stamping link. In the case of cold foil, the appearance is produced by offset printing or silk-screen printing, and in the case of hot foil, the appearance is produced by engraved raised lines on the bronzing plate 10.
Step S130, adding a reflective or semi-reflective medium on the surface of the information layer 3 to form a reflective layer 4; the reflective layer 4 serves to enhance the reflection efficiency of the information layer 3 and to enhance the brightness of the pattern. The type of the coating medium is determined according to the requirements of reflection efficiency and hue, and common media for forming the reflecting layer 4 comprise Al, Cu, Ag and SiO2MgF, ZnS, etc., and other simple metals and compounds capable of enhancing reflection.
In this embodiment, the method further includes step S140: and a connecting layer 5 is additionally arranged on the reflecting layer 4 to form a hot stamping film 11. The reflection layer 4 is formed by adding a reflection or semi-reflection medium on the surface of the information layer 3 by adopting a coating process, wherein the coating process is evaporation coating or vacuum coating, and whether a hot melt adhesive layer, a coupling layer, a pressure sensitive adhesive and other connecting layers are added or not is determined according to a transfer process.
