Abstract
The present invention discloses a fabric film structure coating material for printing digital code. It includes a fibre fabric and polyvinyl chloride film combined fibric film structure base material, and the exterior of said base material is coated with ethyl polyaminoformiate resin coating material (bottom adhesive coating layer), and is characterized by that the exterior of said bottom adhesive coating layer if coated with macromolecular chemical coating material (surface water-prooff coating material). The surface of said invented fabric film structure coating material possesses the advantages of water-proofing, moisture-resisting, wear-resisting and no yellowing, etc., can be used for printing digital code and pattern.
Description
The present invention relates to the fabric film structural coating material that a kind of digital printing device uses.
Fabric film structural coating material for digital printing commonly used is that to be coated with polyvinyl alcohol ester on membrane structure be host, adds an amount of fine grained powder, makes moist with reduction and after-tacks coefficient, reaches the illusion of rapid ink drying.Because of the polyvinyl alcohol good hydrophilic property, meet water and can make the fabric film structural coating material degraded, so these type of digital printing works can not be water-fast, moistureproof, unless back of the body protection is mounted in reprocessing, just can prolonged preservation.In addition, digital printed material need just can reach effect preferably with printing ink is supporting usually, so every kind of PRN device is all wanted special-purpose digital printing record material, the printing cost is additionally increased.
The purpose of this invention is to provide a kind of fabric film structural coating material for digital printing, it can dry fast and effectively printing ink, again can waterproof, protection against the tide, wear-resisting.
The present invention realizes by following technical scheme, it comprises the base material that fabric and polyvinyl chloride film are formed, scribble polyurethane resin coating (be commonly called as and be the primer coating) on the base material, its structural feature is to scribble the polymer chemistry coating that component is inorganic ash, polyvinyl alcohol, oxalic dialdehyde polymkeric substance (being commonly called as surperficial water resistant coating) on the primer coating.
The component concentration of polymer chemistry coating is:
Inorganic ash 35-45 part (weight ratio)
Polyvinyl alcohol 140-180 part (weight ratio)
Oxalic dialdehyde 32-38 part (weight ratio)
200 parts in water (weight ratio)
Inorganic ash is a kind of ultra tiny noncrystal porous gas-phase silicon, and its particle diameter is 0.3 micron.
Polyurethane resin coating can be used to water-fast, anti-xanthochromia, increases the density and the intensity of its coatingsurface and base material, and polymer chemistry coating purposes is water-fast, wear-resisting.
The preparation method of fabric film structural coating material for digital printing, its process flow steps is as follows:
1) get the fiber weaving cloth of 280-500 micron thickness and the polyvinyl chloride film of 80-120 micron thickness earlier and be combined into the fabric film structural base material through hot calender,
2) with general coating apparatus, the fabric film structural base material is placed on the equipment, by base material operation guide wheel, the primer coating (polyurethane resin) that is coated with 4 gram/weight per square meters on base material earlier is after baking oven, with 65 ℃-90 ℃/5 seconds, the speed of furling is 30 m/mins, carries out hot-air seasoning, make top coat coating butt thickness reach the 0.6-0.8 micron
3) on the primer coating, be coated with polymer chemistry coating (surperficial water resistant coating) again, the component concentration of this polymer chemistry coating is (weight ratio): the inorganic ash of 35-45 part, 140-180 part polyvinyl alcohol, 32-38 part oxalic dialdehyde, 200 parts of water, with the coat-thickness scraper control surface coating amount of being coated be 40-60 gram/square metre, through baking oven with 90 ℃-110 ℃/5 seconds, the speed of furling is 30 m/mins, carries out hot-air seasoning, make top coat butt thickness reach the 30-40 micron
4) after grinding, the cold solid pressure of pinch roller becomes a useful person then.
The purposes of fabric film structural coating material for digital printing is to can be used as the printed material that various digital printing devices use.
The present invention adopts polymer chemistry coating to make fabric film structural coating material for digital printing have rapid ink drying, waterproof, protection against the tide, wear-resisting, characteristics such as xanthochromia not, can be used for digital printing, figure message printing, clear picture, not dizzy China ink, bright in luster, applied widely, can be used for various PRN devices.
Fig. 1 is preparation method's process flow diagram of the present invention.
The present invention is further illustrated below with reference to drawings and Examples.
Fabric film structural coating material for digital printing comprises fabric and polyvinyl chloride film compound base material, scribble polyurethane resin coating (being commonly called as the primer coating) on the base material, scribbling component on the primer coating is the polymer chemistry coating (be commonly called as and be surperficial water resistant coating) of inorganic ash, polyvinyl alcohol, oxalic dialdehyde polymkeric substance, and its component concentration of present embodiment divides following embodiment to implement.
Embodiment 1, and the component concentration (weight ratio) of polymer chemistry coating (surperficial water resistant coating) is:

Oxalic dialdehyde 35 grams
Water 200 grams
The component concentration (weight ratio) of embodiment 3 polymer chemistry coating is:
Inorganic ash 45 grams
Polyvinyl alcohol 180 grams
Oxalic dialdehyde 38 grams
Water 200 grams
| Content | Standard | ???1 | ??2 | ??3 |
| Viscosity (CPS) | 2000-4000 | 2100 | 2800 | 3600 |
