Abstract
The invention discloses a laser medical film and a preparation method thereof. The PET medical film is prepared directed to the laser printing demand, the film base is prepared from high temperature resistant PET plastics and is subjected to corona treatment, an anti-static layer is coated on one side of the film base and is prepared from polystyrene sulfonate, a laser ink absorption coating is coated on the other side of the film base, and the laser coating contains a nanoscale aluminum oxide powder dispersion liquid. The laser medical film provided by the invention has the advantages of fast printing speed, good imaging effect, high temperature resistance, good antistatic effect, smooth paper feeding, no jamming, applicability to doctor handwriting signing, difficult color fading, and long preservation period.
Description
Technical field
The present invention relates to medical image film field, relate in particular to a kind of laser medical film and preparation method thereof.
Background technology
Along with the Innovation and development of printing technique, medical film has generally taken leave of the with serious pollution conventional silver film epoch, enters the digital printing stage comprehensively.The scheme of main flow adopts inkjet printing mode in the market, outputted to by medical image printing and be coated with on the PET base material film of ink-absorbed coated layer.But inkjet printing speed is extremely slow, and the quality of ink is uneven, easily oxidized under the effect of natural light and heat, causes image to fade.Laser printing speed is fast, and ink powder is fugitive color not, if the output field that can apply to medical film is ideal.But existing film coatings structure and composition are all not suitable for laser printing to be exported, and resistance to elevated temperatures is poor, and static electrification phenomenon is serious, easily causes with the problem such as paper, card.
Summary of the invention
Object of the present invention is exactly the new medical film that a kind of appropriate laser will be provided to print out, this PET medical film prepared for laser printing demand especially, print speed is fast, and imaging effect is good, high temperature resistant, anti-static effect is good, paper feed is smooth, not card, and can supply doctor's handwriting, not fugitive color, retention cycle is long.Another object of the present invention is to provide the preparation method of this film.
The present invention adopts following technical scheme: this medical film comprises PET sheet base, antistatic backing and laser ink-absorbed coated layer, it is characterized in that: described PET sheet base is made up of resistant to elevated temperatures PET, and through sided corona treatment, described antistatic backing is coated on the one side of sheet base, be made up of poly styrene sulfonate, described laser ink-absorbed coated layer is coated on the another side of sheet base, containing nano-alumina powder dispersion liquid in described laser ink-absorbed coated layer.
Film preparation method of the present invention is as follows:
The first step, the poly-vinyl alcohol solution of preparation 10%, the degree of polymerization of polyvinyl alcohol is 3200, and alcoholysis degree is 83%;
Second step, preparation anti-static liquid: add in the aqueous solution of poly-propyl alcohol of 50%-60% by the poly styrene sulfonate solution of 25%-35%, the mass ratio of poly styrene sulfonate solution and poly-aqueous propanol solution is 1:1;
3rd step, is coated on the one side of PET base material by the anti-static liquid of described step 2 and dries, and electrostatic liquid coating weight is 10-30g/m
2;
4th step, the dispersion liquid of preparation containing alumina powder: added by nano-alumina powder in the dispersion liquid of high-speed stirred and make alumina fluid dispersion, the mass ratio that aluminium oxide accounts for dispersion liquid is 15%-25%;
5th step, adds the poly-vinyl alcohol solution of described step one in the dispersion liquid of described step 4, makes laser ink-absorbed coated layer liquid; The mass ratio of poly-vinyl alcohol solution and dispersion liquid is between 1:3-1:5;
6th step, is coated on the another side of PET base material by the laser coatings liquid of described step 5, after the temperature of 80-95 ° of C is dried, obtain finished product film, its coating thickness is 15-30 μm.
Film of the present invention is mainly used in laser printing, significantly can improve the precision of medical imaging, and what solve laser printing follows paper, paperboard problem, has increased substantially the speed of image output.Glossiness, light transmittance all reach the requirement of medical film, antistatic, crease-resistant wear-resisting waterproof, and coating does not come off, not fugitive color, and available common water borne signature pen is write on film, and retention cycle is long.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described in detail.
Accompanying drawing 1 is the Structure of cross section schematic diagram representing film of the present invention.
Detailed description of the invention
