The film coating comprises water-based resin, a wetting agent, silicon dioxide powder, a paint, a PET (polyethylene terephthalate) board and an air drying box, wherein the water-based resin is diluted to obtain a solution A, the wetting agent is added into the solution A, and is uniformly stirred to obtain a solution B, the silicon dioxide powder is added into the solution B, and is uniformly stirred to obtain the paint, the surface of the PET board is coated with the paint, and the PET board is air-dried in the air drying box. The film coating has the beneficial effects that the film coating has high moisture resistance and water resistance, and a film is unlikely to be deformed and curled; the hardness and the stiffness are high, so that convenience is brought to storage and observation; the coating is high in fastness and free of film dropping and separation, so that the film is longer in storage life.
Description
Technical field
Patent of the present invention is related to technical field of medical instruments, more particularly to a kind of novel aqueous ink-jet medical film coating.
Background technology
General medical film includes protective layer, imaging layer, support layer and backing layer from top to bottom.Support is usually used
Used as base material, what PET was easy to produce electrostatic influence printer send piece system to PET (PET), therefore
It is necessary to solve this problem in PET backsize coatings.
The backing layer of medical film in the market is main using gelatin as filmogen, although gelatin is the more commonly used, valency
Lattice also relative moderate, but poor water resistance, are easily deformed and cause film curl；Hardness is poor, the cut ratio left after friction
It is more apparent, the clear of image can be influenceed when being observed using viewbox；In addition, tack of the gelatin in pet sheet face is bad, coating
Before also need to advance priming operation and processed, this also increases the difficulty of coating, increases cost, is also for film yield rate
One very big hidden danger.
Patent of invention content
Patent of the present invention provides a kind of novel aqueous ink-jet medical film coating, possesses good moistureproof water resistance, glue
Piece is unlikely to deform curling；Hardness is high, deflection is good, convenient to preserve and observe；The fastness of figure layer is good, and film, demoulding, the guarantor of film are not fallen
Deposit the life-span longer.
In order to solve the above technical problems, the embodiment of the present application provides a kind of novel aqueous ink-jet medical film coating, its
It is characterised by, including water-base resin, wetting agent, silicon dioxide powder, coating, PET sheet and air-drying box, described water-base resin passes through
Solution A is obtained after dilution, adds wetting agent to be uniformly mixing to obtain B solution in solution A, silicon dioxide powder is added in B solution
After be uniformly mixing to obtain coating, air-dried during coatings are put into air-drying box behind PET sheet surface.
Used as the preferred embodiment of this programme, the solid content of aqueous resin raw material is 1-20% in described solution A.
Used as the preferred embodiment of this programme, the addition of described wetting agent should be controlled in 0.1-0.5%.
Used as the preferred embodiment of this programme, described coating is coated on the table of PET sheet using slope stream extrusion coated technique
On face, coating weight control is in 10-50ml/m2；.
Used as the preferred embodiment of this programme, described air-drying box is dried using hot-air drying technology, wind-warm syndrome control
Below 45 DEG C, thickness is 5-15 microns after coating layer is dried.
One or more technical schemes provided in the embodiment of the present application, at least have the following technical effect that or advantage：
Possesses good moistureproof water resistance, film is unlikely to deform curling；Hardness is high, deflection is good, convenient to preserve and observe；Figure
The fastness of layer is good, and film, demoulding are not fallen, and the preservation life-span of film is longer.
Brief description of the drawings
In order to illustrate more clearly of patent Example of the present invention or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
Some embodiments of patent of the present invention, for those of ordinary skill in the art, are not paying the premise of creative labor
Under, other accompanying drawings can also be obtained according to these accompanying drawings.

Specific embodiment
Patent of the present invention provides a kind of novel aqueous ink-jet medical film coating, possesses good moistureproof water resistance, glue
Piece is unlikely to deform curling；Hardness is high, deflection is good, convenient to preserve and observe；The fastness of figure layer is good, and film, demoulding, the guarantor of film are not fallen
Deposit the life-span longer.
In order to be better understood from above-mentioned technical proposal, below in conjunction with Figure of description and specific embodiment to upper
Technical scheme is stated to be described in detail.
As shown in figure 1, a kind of novel aqueous ink-jet medical film coating, including water-base resin 1, wetting agent 2, silica
Powder 4, coating 6, PET sheet 7 and air-drying box 8, described water-base resin 1 are added by obtaining solution A 3 after dilution in solution A 3
Wetting agent 2 is uniformly mixing to obtain B solution 5, coating 6 is uniformly mixing to obtain after adding silicon dioxide powder 4 in B solution 5, by coating
6 are coated on behind the surface of PET sheet 7 to be put into air-drying box 8 and are air-dried.
Wherein, in actual applications, the solid content of aqueous resin raw material is 1-20% in described solution A 3, using propylene
The backing layer coating being made based on acid resin and polyurethane resin, insulating water-proof after drying and forming-film, will not because of backside coatings because
Hygroscopic deformation causes film curl, solves the not smooth problem of the paper feed caused because of film curl.
Wherein, in actual applications, the addition of described wetting agent 2 should be controlled in 0.1-0.5%, this backing layer coating
After drying and forming-film, with preferable hardness and deflection, it is easy to hand-held sight piece, surface rub resistance, it is to avoid film because of carrying
Now too many scratch causes the unclear problem of image blur.
