Problems solved by technology

[0002] At present, various types of card bases, such as petroleum cards, transportation cards, and consumption cards, are widely used. They are single-purpose, divided into contact cards and contactless cards, and cannot be used universally.
The performance of its card base material cannot meet the requirements of the current bank card with dual-use (contact and non-contact), its Vicat softening point is low, and the card has a high degree of softness, which is not suitable for external chip use

Embodiment 1

[0024] Components and weight percent content are as follows:

[0025]

[0026] Preparation:

[0027] The raw materials are respectively metered into the high-speed kneader and kneaded at a temperature of 110°C. The high-speed kneader rotates at a speed of 600 rpm, then cooled and stirred at a temperature of 50°C, and extruded by a planetary extruder at a temperature of 190°C. ℃, the extrusion temperature of the single-screw extruder is 140°C, and finally the five-roll calender is used for calendering, and the processing temperatures are: 190°C for No. ℃.

[0028] The product is tested using GB and DIN standards, and the results are shown in attached tables 1, 2 and 3:

Abstract

The invention discloses a calendering base material for a bank double-interface intelligent card and a preparation method of the calendering base material for a bank double-interface intelligent card. The calendering base material for a bank double-interface intelligent card is prepared from the following components in weight percentage: 49-53% of polyvinyl chloride resin, 20-25% of vinyl chloride-vinyl acetate copolymer resin, 7-8% of methyl methacrylate-butadiene-styrene copolymer, 2-3% of butyltin mercaptide, 0.5-0.7% of internal lubricant, 0.5-0.7% of external lubricant and 10-13% of active titanium dioxide. The double-interface intelligent card calendering base material considers the high-temperature laminating adhesion force of an internal chip and a rear coil card matrix, high-temperature resistance of the chip and the coil and the rigid-flexible characteristic of an external chip card matrix, and an equipment condition for producing the calendaring base material for a bank double-interface intelligent card (contact type and non-contact type) is realized.

Description

technical field [0001] The invention relates to a calendered base material for non-contact or contact smart cards. Background technique [0002] At present, various types of card bases such as petroleum cards, transportation cards, and consumer cards that are widely used have a single purpose, and are divided into contact cards and contactless cards, which cannot be used universally. The performance of its card base material cannot meet the requirements of the current bank card with dual-use (contact and non-contact). Its Vicat softening point is low, and the card has a high degree of softness, which is not suitable for external chips. Contents of the invention [0003] The technical problem to be solved in the present invention is to disclose a calendered base material for bank dual-interface smart cards and a preparation method thereof, so as to overcome the defects in the prior art and meet the development needs of dual-interface card base materials for banks and relate...
