Description
Technical field:
The present invention relates to ink jet printing film field, relate in particular to a kind of ink jet printing film and preparation method thereof.
Background technology
Along with the development of technology, the ink jet printing film that digitlization prints is development in recent years a kind of New video film faster.At present, medical film selects the PET sheet of a kind of blueness or white as base material, ink-absorbed coated layer in coating, and the apparent mass of film is also fine, but cost is too high.
Blotting amount and the blotting stability of ink-absorbed coated layer have considerable influence to printing effect, and the color representation power of blotting amount to film has significant impact, and the waterproof ability of blotting stability to film has a direct impact.Adopt the thickness increasing ink-absorbed coated layer to strengthen blotting amount under normal circumstances, adopt simultaneously and dye with the better dyestuff of film electrostatical binding power.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the invention is to provide a kind of ink jet printing film, this film has the performance of waterproof, and the blotting amount of the more common film of its blotting amount is larger, and cost is lower.Doctor can be made more to go out conditions of patients by Accurate Diagnosis.
For realizing above-mentioned technical problem, the technical solution used in the present invention is: a kind of ink jet printing film, comprises substrate, dyed layer and ink-absorbed coated layer, and described substrate is made up of transparent material, described dyed layer is blue or white, and described ink-absorbed coated layer is multilayer laminar structure.
Further, between described ink-absorbed coated layer layer structure, aperture is different, and ink-absorbed coated layer layer structure is positioned at the side of substrate.
Further, the aperture of described ink-absorbed coated layer layer structure becomes large by away from substrate successively near substrate direction.
Further, described ink-absorbed coated layer is made up of 2-6 laminate, and described ink-absorbed coated layer thickness is 2-6 μm.
Further, described dyed layer thickness is 1-2 μm.
A preparation method for ink jet printing film, comprises the following steps: the preparation of S1, dyed layer: dyed layer adopts aqueous polyurethane dispersing liquid and dyestuff to be mixed with, and the mass ratio of described aqueous polyurethane dispersing liquid and dyestuff is 50:1 ~ 20:1; The coating of S2, dyed layer: dyed layer dissolution homogeneity is coated transparent base; The preparation of S3, ink-absorbed coated layer: ink-absorbed coated layer has multilayer laminar structure, in each layer structure, porous material footpath is different, and described porous material is silica or alundum (Al2O3); The coating of S4, ink-absorbed coated layer: ink-absorbed coated layer has once been coated with.
Further, described dyed layer thickness is 1-2 μm.
Further, the coating of described dyed layer also has the step of drying afterwards, and bake out temperature is 50-90 DEG C, and drying time is 10-120min.
Further, in the preparation process of described ink-absorbed coated layer, porous material adopts high speed dispersor dispersion, linear velocity 10-15m/s, jitter time 1-2 hour.
Further, in the application step of described ink-absorbed coated layer, coating speed 1-20m/s.
In dyed layer preparation, aqueous polyurethane dispersing liquid adopts 70-90 DEG C of distilled water to dissolve, and can accelerate the dispersion of aqueous polyurethane dispersing liquid.The mass ratio of dyestuff and aqueous polyurethane dispersing liquid controls between 1:20-1:50, can adjust the shade of chromatograph.The amount of solid content controls at 10%-15%, can adjust the thickness of chromatograph by controlling solid content, and dyed layer THICKNESS CONTROL, at 1-2 μm, makes dyed layer can well display background color, but can not disturb the observation of ink absorbing layer.
In the preparation process of ink absorbing layer, by regulating the mass ratio of each composition, thus adjust the content of crosslinking agent of each layer structure, thus increase the stability of its structure, particularly in sandwich construction, content that can be different by the structure sheaf that adjustment is different, increases integrally-built stability.Also the stability of structure can be increased by the increase of solid content.Porous silica adopts high speed dispersor dispersion can prepare dispersion liquid more uniformly.In the linear velocity of 10-15m/s, within jitter time 1-2 hour, dispersion effect is better.
After the coating of ink absorbing layer, baking temperature is within the scope of 50-120 DEG C, dries within the scope of 5-20min.
Hole becomes large by away from substrate successively near substrate direction.Meanwhile, also identical hole layer repeatedly can be arranged, ink dye is not easily separated out after entering internal layer, can strengthen water proofing property.
Beneficial effect: compared with prior art, advantage of the present invention is: by arranging dyed layer, and blue or white background color can be completed by unified base material, can effectively reduce costs; By arranging the mode with the ink-absorbed coated layer of layer structure, improve the blotting amount of coating; Meanwhile, the aperture arranging the ink-absorbed coated layer of layer structure becomes large by away from substrate successively near substrate direction, coloring material can be made more to be combined with the porous mass of internal layer and colloid, increase waterproof ability further; The preparation of dyed layer and the preparation of ink-absorbed coated layer are separately carried out, and the preparation of coating on ink absorbing layer of dyed layer does not affect, and better can be coated with ink-absorbed coated layer; Ink-absorbed coated layer adopts high speed dispersor to disperse in preparation, and can strengthen the dispersiveness of silica, alundum (Al2O3), hole is more even; Ink-absorbed coated layer layer structure has once been coated with, and coating stability is strengthened, coating layering Stability Analysis of Structures.
