Embodiment 1

[0066] The invention provides an adhesive film, comprising: a modified BOPET film, one side of the modified BOPET film is coated with an anti-scratch coating, and the other side is coated with water-based glue.

[0067] The modified BOPET film adopts a three-layer structure, wherein

[0068] The middle layer is PET, and the surface layer is modified BOPET layer;

[0069] The modified BOPET layer includes the following components in parts by mass:

[0070] 42-72 pieces of pet slices;

[0071] 20-50 pieces of PCTG slices;

[0072] Silicon masterbatch 8 parts.

[0073] Among them, Pet slices are such as but not limited to Pet slices BD48 of Liaoyang Petrochemical, with an intrinsic viscosity of 0.71;

[0074] The PCTG chip, for example but not limited to JN200, is the PCTG chip of Korea SK, which is an amorphous polyester with a CHDM (1,4 cyclohexanedimethanol) content of more than 50%, a tensile strength of 53 MPa, and an elongation at break of The rate is 340%;

Abstract

The invention relates to a high-performance BOPET water-based adhesive film, card and preparation method that is resistant to damp heat, aging and scratch, and the adhesive film includes: a modified BOPET film, one side of the modified BOPET film is coated with an anti-scratch paint , and the other side is coated with water-based glue; the adhesive film of the present invention has good comprehensive performance, the surface is scratch-resistant, and the yield of the customer's card is improved; it is resistant to heat and humidity and has high peel strength, and it is suitable for a wide range of inks, which is convenient for customers to choose Printing ink and reduce cost; use water-based glue, friendly to the environment.

Description

technical field [0001] The invention relates to the field of film processing and water-based glue coating. Background technique [0002] At present, the domestic production of bank cards and various smart cards (such as social security cards, fuel cards, road toll cards, etc.), the protective surface layer used on the surface is PVC with adhesive film, and the adhesive side is the surface that is bonded to the printing ink , Most of the glue used is water-based, because it is environmentally friendly and has no air pollution, and the production safety is high. However, the common disadvantage of water-based adhesive films is that they are not resistant to humidity and heat, and the adhesion to the ink layer is generally not strong, and some of the surface layers will peel off or crack during use. Collected PVC film from several domestic manufacturers, after hot pressing with the ink test card, tested the peel strength of the card base before and after aging, and found that ...
