Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] like figure 1 The manufacturing process of a high-temperature-resistant laminated certificate material shown, the steps are as follows:

[0033] 1) Coat the release layer on the 20μm PET base film, the thickness of the release layer is 1.2~1.5μm; the drying temperature is 100℃~155℃, the speed is 90m / min, drying and winding:

[0034] 2) Coat the information layer on the release layer, the thickness of the information layer is 1.0~1.2 microns; the drying temperature is 100°C~135°C, and the speed is 100m / min;

[0035] 3) After drying and rewinding, use a positioning embossing machine to perform positioning embossing of laser holographic patterns. The embossing temperature is 183°C~188°C, the embossing speed is 32~38m / min, and the molding pressure is 4~4.2 MPa; at the same time, the longitudinal direction is embossed Plain surface tracking...

Abstract

The invention discloses a manufacturing technology of a heat resisting laminating document material. The present laminating document material fails to meet a requirement on thirty-second temperature tolerance at the temperature of one hundred and thirty five DEG C. With the adoption of the manufacturing technology of the heat resisting laminating document material, after the positioning impression, a laser transfer basement film is aluminized in vacuum; through a positioning aluminum-washing technology, after the positioning protection on a longitudinal face tracking line and a transverse cursor identifying block, the aluminum-washing is performed; subsequently, the laser transfer basement film is plated with a zinc sulfide transparent medium in a vacuum evaporation way; next, a phosphor pattern is printed; a printable thermosensitive gel is coated; the laser transfer basement film is compounded with an adhesive layer provided with anti-sticking silicon paper; and finally, the laser transfer basement film is positioned and die-cut into finished paper consisting of a plurality of small sheets. The document material manufactured by the manufacturing technology is characterized in that the document material is provided with a whole transparent positioning holographic pattern or a whole positioning fluorescent ink pattern; the thermosensitive adhesive layer is not only used as a bonding compound transfer glue during laminating, but also used as a personalized information and photo printing material; and the requirement of the thirty-second temperature tolerance at the temperature of 135 DEG C in the laminating technology is met.

Description

technical field [0001] The invention relates to an anti-counterfeiting material used in the field of public security, in particular to a manufacturing process of a high-temperature-resistant laminated certificate material. Background technique [0002] Transparent holographic anti-counterfeiting technology, as a high-tech anti-counterfeiting method, has been widely used in domestic card and anti-counterfeiting fields. Why is good anti-counterfeiting technology abandoned on the second-generation ID card? The reason is: this anti-counterfeiting technology of non-positioning transparent holographic edge plastic sealing has fatal shortcomings. First, the transparent holographic card is sandwiched in the middle of the original paper card in the form of anti-counterfeiting film and sealed by the edge. In this form, the edges are easy to disengage and change easily, which gives false witnesses an opportunity to take advantage of it, so that the anti-counterfeiting effect cannot be...
