Problems solved by technology

[0006] However, the current smart cards made of polylactic acid materials have the following problems: first, the polylactic acid materials are laminated and bonded under the condition of 130°C to 210°C, and the materials are easily deformed due to force, which may easily lead to delamination between the polylactic acid materials; The second is that the surface of the polylactic acid material is printed on the surface of the polylactic acid by screen printing or a four-color rubber brush. After lamination, the ink adhesion is low, resulting in incomplete color on the surface of the smart card.
For example, when the ink is directly printed on the surface of polylactic acid, it can be colored normally, but due to the subsequent processing technology, each layer of the smart card needs to be heated at 120°C to 160°C, under a pressure of not less than 3Mpa and for 15 to 30 minutes. Lamination is carried out under lamination conditions. In this proc

[0052] Combine below image 3 Introduce the manufacturing process of the smart card. First, step S1 is performed to make the base material layer using environmentally friendly and degradable materials. In this embodiment, the base material layer includes a first base material layer and a second base material layer, and an installation cavity needs to be provided on the first base material layer . Specifically, materials such as polylactic acid can be used to make the first base material layer and the second base material layer respectively.

[0053] Then, step S2 is performed to make a starch-based adhesive. In this embodiment, the starch-based adhesive is prepared by cross-linking starch-modified polyvinyl acetate emulsion and polyurethane prepolymer. Specifically, the preparation process of starch-modified polyvinyl acetate emulsion is as follows: starch, Add polyvinyl alcohol and water to a four-necked flask with a nitrogen protection device at the same time, stir and he...

[0080] The structure of the smart card produced in this embodiment is the same as that of the three smart card embodiments introduced above, and the structure of the smart card will not be introduced here.

[0081] Combine below Figure 6 Introduce the process of this embodiment. First, step S11 is performed to make the base material layer using environmentally friendly and degradable materials. In this embodiment, the base material layer includes a first base material layer and a second base material layer, and an installation cavity needs to be provided on the first base material layer , For example, materials such as polylactic acid can be used to make two substrate sublayers. Since the two base material sub-layers need to be bonded with a synthetic resin adhesive, the step of bonding the two base material sub-layers is performed after the synthetic resin adhesive is prepared. Certainly, the base material layer may also include a first base material layer, an intermediate...

Abstract

The invention provides an environment-friendly degradable intelligent card and a manufacturing method thereof. The intelligent card comprises a base material layer, an intelligent chip is embedded inthe base material layer, a printing layer is formed on one surface of the base material layer, and the base material layer is made of a degradable material; the base material layer comprises two or more base material sub-layers, and every two adjacent base material sub-layers are bonded through a preset adhesive; and/or the printing layer is adhered to the surface of the base material layer through a preset adhesive. The method comprises the steps that a degradable material is used for manufacturing a base material layer, and a mounting groove is formed in the base material layer; one surfaceof the base material layer is coated with a preset adhesive, ink is printed on the surface coated with the preset adhesive to form a printing layer, and after the base material layer and the printinglayer are laminated, the intelligent chip is installed in the installation groove. The card base of the intelligent card is made of the environment-friendly degradable material, the intelligent card can be naturally degraded after being scrapped, and pollution to the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to an environment-friendly degradable smart card made of degradable materials and a manufacturing method of the smart card. Background technique [0002] Smart cards are commonly used in people's lives, such as bank cards, public cards, membership cards, etc. that people use daily. The current smart card usually includes a card base, and a smart chip is arranged in the card base, and a preset program can be run in the smart chip, and user data can be recorded. [0003] Usually, the smart card base is made of PVC (polyvinyl chloride) resin. Because the PVC resin contains plasticizers, anti-aging agents and other auxiliary materials that are toxic and difficult to recycle, scrapped smart cards are basically discarded directly. It will slowly decompose and release hydrogen chloride gas, which is harmful to the human body. Therefore, the environmental problems brought by smart card...
