Problems solved by technology

[0005] PHA, polyhydroxyalkanoate, PHA films in the prior art are generally used for disposable packaging sheets, printing sheets, decorative sheets, lack of quality control indicators, and cannot meet the special requirements of smart card packaging
[0006] In order to avoid the wear of the printed film pattern, smart cards are generally equipped with a protective film, but in order to improve the processing performance of the PHA / PETG blend film, more processing aids are used, and there are more precipitates on the surface of the hard film, and the peeling force after lamination Small; large shrinkage rate; poor toughness makes it difficult to make embossed characters; surface bubbles, crystal points, and holes are many, and cannot be printed precisely; poor light transmission; poor tensile strength

Abstract

The invention discloses a PHA protective membrane for a smart card and a preparation method of the PHA protective membrane. The membrane comprises the following components in percentage by mass: 30wt%-40wt% of PHA resin, 50wt%-60wt% of PETG resin, 0.1wt%-0.8wt% of carboxymethyl cellulose sodium, 2.6wt%-3.5wt% of a PETG resin processing aid, 0.1wt%-0.3wt% of a plasticizer, 0.1wt%-1wt% of a lubricating agent, 0.1wt%-0.5wt% of an antioxidant, 4.5wt%-5.0wt% of a compatibilizer, 0.3wt%-0.5wt% of an ultraviolet light absorber and 0.3-0.5wt% of an antistatic agent. The membrane is prepared by adopting a rolling process; the protective membrane disclosed by the invention is prepared into a hard sheet employing the rolling process; use of the processing aid is reduced; a surface layer of the protective film is prevented from generating educts, thus the peel strength is improved, and the protective membrane is prevented from being easily stripped to crack.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic polyester, and in particular relates to a PHA protective film for smart cards and a preparation method thereof. Background technique [0002] Smart cards are divided into contact IC card (Integrated Circuit Card integrated circuit card, also known as Smart card smart card), non-contact RFID card (Radio Frequency Identification radio frequency identification card) and dual interface card (with both IC card and RFID card) according to the communication interface mode. card communication interface), they all embed microelectronic chips into the substrate, and complete the printing on the surface of the card, mask protection, and finally lamination. Therefore, the smart card is made by laminating the base material, printing film and protective film sequentially and pressing them together. [0003] The way of making smart cards is full-page printing, that is, the number of cards on the printed f...
