Abstract
The invention relates to a printing film, which comprises a carrier layer and a pattern layer printed on the carrier layer, wherein the pattern layer has a three-layer structure; a first layer is a polyurethane printing ink layer containing double-component polyurethane printing ink; a second layer is a pattern-covering printing ink layer containing acrylic resins and mixed solvents; a third layer is a printing ink layer containing the double-component polyurethane printing ink and other printing ink binders; and because of the specific components of each ink layer and the proportion thereof, the printing film provided by the invention has higher stretch rate and is uniformly stretched and the pattern layer is characterized by water insolubility and cracking resistance. A printing process for using the printing film provided by the invention to dip and coat a workpiece can be used for realizing the one-step printing for the double sides of the workpiece, especially a panel product, thereby greatly increasing the printing efficiency.
Description
Technical field
The present invention relates to a kind of printing film, particularly relate to a kind of typography of in water, finishing this film of film and its production and application of the disposable printing of sheet material double face in vertical dip-coating mode.
Background technology
The dip-coating technology in past is referred to as " printing stock " technology, use the printing stock technology can with the figure line in water trans-printing on the product of all kinds of materials, PVC material for example, ABS material, metal etc.Print film generally comprises printing carrier PVA rete and the picture and text layer that is printed on the PVA in the used water.
Printing comprises print film is tiled on the water surface in the water; behind the water-solubility PVA membrane degradation; spray reducing agent to figure line film surface; make the figure line become liquid state; the angle inclined of workpiece with the 20-30 degree is pressed in the water; if the figure line on the printing sheet material then protects the sheet material one side parallel being pressed in the water of one side with plastic foil.After the printed washing, protect printing surface again, print another side in the same way, that is,, then need twice printing if a sheet material requires the two-sided figure of having line.
Existing printing stock film is owing to all be to adopt printing ink is printed directly on the PVA water-soluble film in the technology of system film, and ink lay directly contacts with the PVA water-solubility membrane, when the PVA film absorbs water when saturated ink lay also because of the fragmentation that absorbs water.Print film is also because the character of the printing ink that ink lay is selected has caused film surface hardness height in this water, tough and tensile frangible, rub resistance is poor, rete easily splits frangible, so, PVA suction after the film entry, thus ink lay also easily in water very fast dispersion to cause being printed as power in the water low, and print film does not have tension force, no extensibility, can only be with parallel from top to bottom horizontal being pressed in the water of object, print film consumption is greater than 300%, the processing cost height, because rupture of membranes rate height is printed as power only 20%, and need the two sides of twice pair of sheet material series products to print, and can not finish the disposable printing in sheet material two sides in vertical dip-coating mode, cause printing efficiency extremely low.
