Description
Technical field
The present invention relates to field of medical article technology, relate to medical laser printing film specifically.
Background technology
Conventional medical image film take photosensitive silve halide material as medium, a diagnostic medical image film just can be obtained through overexposure, development, multiple link such as fixing, dry, this wet processing technology complicated operation, to waste time and energy and seriously polluted, its use is subject to increasing restriction.Along with the development of technology, the laser printing film that digitlization prints is development in recent years a kind of New video film faster, can use laser printer types.Through collection, process Digital Medical Image, directly through laser printer types on film, can be used for the output of the medical examination such as medical ultrasonic and X-ray report and image.
In medical laser print procedure, fixing temperature is up to 200 DEG C, larger pressure is produced during fixing fusing, this just requires that our laser printing film printing ink suction layer will have very high temperature tolerance, printing ink suction layer and base material will have very strong adhesive force, our medical laser printing film of such guarantee printing ink suction layer under high temperature, condition of high voltage is not melted, and does not depart from base material.Patent CN201210577308.3 discloses a kind of environmental protection medical laser printing film, and the main component of its exclusive laser printing ink absorbing layer is polyacrylate emulsion.
Summary of the invention
For the above-mentioned problems in the prior art, the invention provides a kind of medical laser printing film, under high-temperature and high-pressure conditions, clear picture can be printed, Image Saving good stability.
In order to solve the problem, the technical solution adopted in the present invention is as follows:
Medical laser printing film, comprise the coating on base material and base material, described base material comprises transparent or semitransparent PET sheet, described coating comprises exclusive laser printing ink absorbing layer, antistatic backing and intermediate adhesive layer, intermediate adhesive layer is coated with in the one side of base material, the another side of intermediate adhesive layer scribbles exclusive laser printing ink absorbing layer, and the another side of base material is also be coated with intermediate adhesive layer, and the another side of intermediate adhesive layer scribbles antistatic backing;
Described exclusive laser printing ink absorbing layer comprises the component of following mass fraction: EVA resin 93%-97%, brightening agent 0.3%-0.7%, dispersant 1%-2%, antistatic additive 2%-5%.
Described exclusive laser printing ink absorbing layer comprises the component of following mass fraction: EVA resin 95%, brightening agent 0.5%, dispersant 1.5%, antistatic additive 3%.
Described antistatic backing comprises the component of following mass fraction: adhesive 40%-50%, flatting silica 10%-15%, polyaniline antistatic agent 10%-30%, dispersant 1%-3%, levelling agent 3%-5%, solvent 4%-30%.
The present invention is before finally selecting the main component of EVA resin as exclusive laser printing ink absorbing layer, many contrast tests of having selected other material to do, the such as resin of polyvinyl butyral resin (PVB) resin, acrylic resin, pure-acrylic emulsion, Silicone acrylic emulsion, water-borne acrylic resin, VAE emulsion, EVA resin, epoxy resin, polyurethane resin, polyvinyl chloride resin, aqueous acrylic emulsion etc. tens kinds, the experiment of up to a hundred times, below enumerate PVB resin, acrylic resin, pure-acrylic emulsion as experiment representative:
One, select polyvinyl butyral resin (PVB) resin as the main component of exclusive laser printing ink absorbing layer, because PVB resin has good solvent adaptability, softening point is very high, does the following experiment unit of the following data (for gram) by PVB resin:
Experiment conclusion: test according to the PVB resin of different model, detect, find the resin that molecular weight is little, temperature tolerance is bad, can not realize printing; The resin that molecular weight is larger, heatproof is very good, and in print procedure, the adhesiveness of laser toner is bad, and the resolution ratio of printed drawings picture is inadequate.So PVB resin is unfit to do laser printing ink absorbing layer.
Two, select acrylic resin as the main component of exclusive laser printing ink absorbing layer, experiment following (following data unit be gram):
Experiment conclusion: experimentally situation finds, the vitrification point (Tg) of acrylic resin is very large on the impact of print performance, the resin that Tg is low, producing, the properties in batching, coating process is all better, but during laser printing, coating temperature tolerance is poor, and print procedure floating coat comes off, film card machine when causing printing; The resin that Tg is high, print temperature tolerance good, print quality is higher, but coating itself is too crisp, and coating easily ruptures, be full of cracks, affects the serviceability in later stage.So acrylic resin also should not be used as laser printing ink absorbing layer.
Three, select pure-acrylic emulsion as the main component of exclusive laser printing ink absorbing layer, experiment following (following data unit be gram):
Experiment conclusion: select the pure-acrylic emulsion of different model to be contrast experiment, find that the print performance of pure-acrylic emulsion is fine, picture quality is also fine.But in production process, the proportioning process of pure-acrylic emulsion is complicated, and operation requirements is high, and during coating, emulsion produces a large amount of bubble, and coating is easily shunk in dry run, and the phenomenon at " volcanic crater " appears in coating.So the production adaptability of pure-acrylic emulsion is too poor, should not select.
Described exclusive laser printing ink absorbing layer is by Screw Extrusion, the direct film of film technique in intermediate adhesive layer, and solvent-free and exhaust emission, security is high, is applicable to the production line balance of brakingization.
Adopt ion blower to carry out elimination electrostatic to the base material of film, avoid specimen page " adhesion " phenomenon that film in use occurs.
Beneficial effect: because anti-aging, the resistance to ozone intensity of EVA resin is good, non-toxic, water-fast, wear-resistant, adhesion strength is high, and film prints clear picture in printing, Image Saving good stability, color reducibility is good, good weatherability, and film nothing " adhesion " phenomenon in laser printing process.
