PET is an abbreviation for Polyethylene terephthalate, abbreviated as PET or PETP. The Chinese meaning is: the polyterephthalic plastics mainly comprise polyethylene terephthalate (PET) and polybutylene terephthalate (PBT). Polyethylene terephthalate is also commonly referred to as polyester resin. It is a polycondensate of terephthalic acid and ethylene glycol, together with PBT, generally referred to as thermoplastic polyester, or saturated polyester.

The middle layer 130 is made of three layers of ABS material. The intermediate layer 130 is provided with a chip therein to make the card have an IC card function. The texture of the upper PET film material and the lower PET film material of the first outermost layer 110 is in the same direction. The texture of the upper layer PET film material and the texture of the lower layer PET film material of the second outermost layer 150 are in the same direction. The texture of the upper and lower PET materials of the first, outer layer 120 is co-directional. The texture of the upper and lower PET materials of the second outer layer 140 is co-directional. The texture is co-directional so that the first outermost layer 110, the second outermost layer 150, the first minor outer layer 120, and the second minor outer layer 140 do not exhibit distortion or unevenness during the manufacturing process.

The preparation method of the card provided by the embodiment of the invention is used for preparing the card. A method of making a card of an embodiment, comprising the steps of:

the first outermost layer 110, the first secondary outer layer 120, the intermediate layer 130, the second secondary outer layer 140 and the second outermost layer 150 are sequentially laminated together to form a laminated structure, wherein the first outermost layer 110 and the second outermost layer 150 are both PET or PETG glue film layers. The laminated structure is pressed together by a lamination process to form a card. And forming a tactile recognition pattern 160 on the upper surface of the card to obtain the card. That is, the lamination process allows the layers of the laminate structure to be fused together to form the tactile recognizable pattern 160 as a card.

The lamination process comprises the following specific steps:

the laminated structure is disposed between a first platen and a second platen. The laminated structure is hot pressed under the conditions that the pressure is 75 kg-85 kg and the temperature is 130 ℃ to 140 ℃. And then carrying out cold pressing on the laminated structure under the conditions that the pressure is 85 k-95 kg and the temperature is 18 ℃ to obtain the card. Wherein the hot pressing time is 28min, and the cold pressing time is 28 min.

The first platen has a first working surface corresponding to the first outermost layer 110. The first working surface is treated with a matte surface so as to form a matte surface on the side of the first outermost layer 110 away from the first secondary outer layer 120. The second platen has a second working surface corresponding to the second outermost layer 150. The second working surface is treated with a matte surface so as to form a matte surface on the side of the second outermost layer 150 remote from the second secondary outer layer 140. In order to obtain the tactilely recognizable pattern 160, the second work surface is also processed by three-dimensional laser engraving to be able to form the tactilely recognizable pattern 160. Since the tactile recognizable pattern 160 is formed by melting the material of the second outermost layer 150 and then cooling the melted material during the lamination process, if the tactile recognizable pattern 160 protruding from the surface of the second outermost layer 150 is desired, the second working surface is processed to have a concave structure matching the tactile recognizable pattern 160 by three-dimensional laser engraving. The concave structure corresponding to the tactile recognizable pattern 160 on the second working surface may not be processed with a dummy surface, so as to improve the touch recognition of the tactile recognizable pattern 160.

In this embodiment, the tactilely recognizable graphics 160 are braille characters 160. The braille characters 160 are located in the second outermost layer 150. The braille characters 160 project outwardly of the second outermost layer 150. The second working surface is formed with a concave structure corresponding to the convex points of the braille characters 160 by three-dimensional laser engraving process. The height/size/position of the concave structure meets the technical specification requirement for the manufacture of the disabled certificate card of the Chinese disabled person association. The first pressing plate and the second pressing plate are both made of manganese steel plates. It is understood that in other embodiments, the first and second platens may be made of other metal materials.

In the preparation process of the card, all the components need to be superposed and combined, the number of layers can be reduced or increased in order to increase the card function, but the total thickness is fixed and is generally within 0.9mm +/-0.02 mm. If the card being produced is not a smart card, the middle layer 130 is simply three layers of ABS material that are not treated. If the prepared card has a non-contact chip, for example, an IC card function, the intermediate layer 130 is prepared by the following steps:

and winding the three layers of ABS materials according to the set specification, mounting a chip and welding. And hot pressing the laminated structure by using a matte steel plate under the conditions that the pressure is 75 kg-85 kg and the temperature is 130-150 ℃. And then carrying out cold pressing on the laminated structure under the conditions that the pressure is 85 k-95 kg and the temperature is 18 ℃ to obtain the intermediate layer. Wherein the hot pressing time is 28min, and the cold pressing time is 28 min.

During the process of preparing the first and second

outer layers

120 and 140, the upper and lower PET materials of the first outer layer 120 have the same grain direction. The texture of the upper and lower PET materials of the second outer layer 140 is co-directional. So that no distortion irregularities occur during the lamination process.

In this embodiment, the preparation method of the card further includes the following steps:

The card main body service crowd prepared by the embodiment is a visually impaired person, and has the advantages of reasonable design, simple card structure and easy production process operation. Compared with PVC materials, the card has the characteristics of high temperature resistance, acid and alkali resistance and high hardness, so that the prepared card is not easy to bend and break. Because the first working surface and the second working surface are subjected to matte treatment, the prepared card has a fine matte appearance and good hand feeling, and has higher quality than cards produced by PVC materials. And laminating the second working surface at 130-140 ℃ by three-dimensional laser engraving treatment and combining the characteristics of the PET material to meet the adhesive force among all the component layers of the laminated structure, thereby obtaining the integrated card. The formed braille has obvious effect, safe and full hand feeling and better identification. Thereafter, a standard card is made. The appearance of the standard card conforms to the IS07816 standard, the electrical property reaches the IS014443 standard, and the use effect IS good. The PET material is a natural degradation material, so that the PET material is more environment-friendly; the wear resistance of the card is improved due to the matte effect, the service life is long, and the card is more cost-saving and environment-friendly.
