Environment-friendly degradable intelligent card and manufacturing method thereof

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...

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 process, the ink is easy to be layered. When the smart card is cut, the edge of the smart card is prone to the problem of separation of the ink and the film, that is, the phenomenon of edge burst. This is because The adhesion of ink on the surface of polylactic acid is less than 1N / cm, which is caused by the low adhesion

Therefore, smart cards made of polylactic acid can only be used in the field of membership cards or retail cards at present, and cannot meet the requirements of the bank card industry

[0007] In addition, since the substrate layer made of polylactic acid material is often thin, it cannot meet the requirements of thicker smart cards. Therefore, if a dual-interface card or a smart card with a smart chip is installed, the substrate layer often requires a multi-layer structure.

However, if multiple substrate layers are directly laminated, the substrate layers are easily separated from each other, resulting in delamination of the smart card
