Description
Technical field
It is the utility model relates to PET card band glue film, in particular to a kind of to be demonstrate,proved with the PET of scratch resistance and anti-static function
Cassette tape glue film.
Background technique
Bank card within Chinese territory at present, the protective layer of member card is mostly PVC (polyvinyl chloride) film, however PVC is not ring
Product is protected, the developed countries such as European Japan of the U.S. have forbidden or gradually forbidden PVC band glue film use in card industry.It takes and generation
Be it is more environmentally-friendly with the better PET of dimensional stability for glue film.
PET strip glue film is to be coated with one layer of hot melt adhesive on the surface without glue PET film, make its print with PET card chip base or
Middle material echos effect with good；PET strip glue film main function is the upper layer and lower layer for being covered on PET card, by laminate
Be heated and pressurizeed, form the very bright surface of PET card, the adhesive force of REINFORCED PET white card and overlay film, with glue film have front and back sides it
Point, front applies any substance, and reverse side is coated with hot melt adhesive.However since the unique chemical characteristic of PET and surface compact make very
Rare hot melt adhesive can be bonded PET, and the hot melt adhesive technology that can be bonded PET often rests in eastern beautiful, manufacturer of the Japan such as Mitsubishi hand
In our PET is greatly limited in the use of card industry.The present invention is by applying one on the lower surface PET
Layer prime coat layer applies common hot melt adhesive again, since prime coat layer has good adhesive force to change pet sheet face again simultaneously PET
Chemical characteristic and the compactness extent for reducing pet sheet face, so that common hot melt adhesive, which is also relatively easy to, is attached to bottoming
This problem is bonded on coating to solve PET difficulty.It is daily simultaneously with the development of the society, the card in life is more and more
The most common card belongs to such more in life, such as: member card, market card, bank card, campus card, VIP card.However most as card
The PET strip glue film of primary raw material does not simultaneously have scratch resistance and antistatic feature, and card This move is drawn in the use of life high frequency
It will appear card surface scratching, main cause is that the PET strip glue film for making card does not have anti-scratch function；PET strip glue film simultaneously
It is easy to friction and generates electrostatic, electrostatic can attract dust in air particle, cause further to scratch and stain, it can be seen that anti-zoned
Wound and it is antistatic be urgent problem.
Utility model content
That the technical problem to be solved by the present invention is to provide a kind of structures is simple, processing cost is low, have anti-scratch and
The PET card band glue film of anti-static function.
In order to achieve the above objectives, the technical solution of the utility model is as follows:
A kind of PET card band glue film with scratch resistance and anti-static function, the PET card band glue film include:
One PET film；
One is coated in the prime coat layer on PET film lower surface；
One is coated in the hot melt adhesive layer on prime coat layer；
One is coated in the scratch resistance aqueous polyurethane layer on PET film upper surface；
One is coated in sour (ester) layer of antistatic polypropylene and/or antistatic polyurethane above scratch resistance aqueous polyurethane layer
Layer.
In one embodiment of the utility model, the prime coat layer with a thickness of 2 μm (micron) -20 μm.
In one embodiment of the utility model, the hot melt adhesive layer with a thickness of 120 μm -150 μm.
In one embodiment of the utility model, sour (ester) layer of the antistatic polypropylene and/or antistatic gather poly- ammonia
Ester with a thickness of 1-5 μm.
In one embodiment of the utility model, the scratch resistance aqueous polyurethane layer with a thickness of 25-30 μm.
In one embodiment of the utility model, sheet resistance of the PET card with glue film is 108~1010Ohm.
In one embodiment of the utility model, surface hardness of the PET card with glue film is greater than 1H.
Through the above technical solutions, the beneficial effects of the utility model are:
The utility model structure is simple, processing cost is low, by coating scratch resistance aqueous polyurethane layer on a pet film and resisting
Electrostatic polyacrylic acid (ester) layer and/or antistatic polyurethane layer, with anti-scratch and anti-static function, and product surface hardness
2H is risen above by pencil hardness HB, product surface resistance is from 1013~1015Ohmmic drop is as low as 108~1010Ohm.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
