METHOD AND DEVICE FOR TRANSFER LAMINATION

摘要

A transfer laminate (35), comprising a carrier film having an adhering decorative element having a solid, pigmented, partially cured decorative layer, is laminated on the decoration side onto a substrate (40) having a temperature between 50 and 70° C. on the decoration side, on which substrate a coating that can be painted over has been applied in the course of a traditional process. The paint layer of the coating that was applied last is still moist and tacky after the intermediate drying thereof. The transfer laminate (35) is laminated onto the still moist and tacky paint layer on the substrate (40), and at least the region of the transfer laminate (35) containing the decorative element is pressed onto the substrate coating over the entire area at a pressure of 0.2 to 5.0 bar for 40 to 240 seconds. Then the carrier film is quickly cooled to a temperature less than 20° C. and then removed from the substrate coating, wherein the decorative element remains on the substrate coating. The device for transfer lamination forms an applicator (10), which comprises: two flexible membranes (20, 22), which are both clamped pressure-tight on a common frame (12) along the perimeter of the membranes in such a way that an intermediate space is created therebetween, in which a flexible warm- or hot-water layer (27) can be enclosed; a chamber (30), which can be filled with compressed air, wherein overall such an arrangement is created that a gradual introduction of compressed air into the chamber (30) moves the two flexible membranes (20, 22) and the flexible warm- or hot-water layer (27) jointly in the manner of a balloon onto the substrate surface (42) to be coated in order to apply the transfer laminate (35) to and press the transfer laminate onto said substrate surface (42) without bubbles.

主权项

1. A method for transfer lamination in which a transfer laminate, comprising a backing foil with an adhering decorative element having a solid, pigmented, partially cured decorative layer,
is laminated by its decoration side onto a substrate, and finally the backing foil is peeled off and removed, characterized in that
a substrate is provided, having a temperature in the range between 50 and 70° C., to which an overpaintable coating has been applied in the course of a conventional painting operation, the last-applied paint film of said coating being still moist and tacky after its interim drying;the transfer laminate is laminated onto this still moist and tacky paint film on the substrate; andat least the region of the transfer laminate that comprises the decorative element is pressed onto the substrate coating for 40 to 240 sec over its full area under a pressure of 0.2 to 5.0 bar, more particularly under a pressure of 0.4 to 5.0 bar; andtoward the end of this pressing phase, the backing foil is cooled rapidly to a temperature in the range from 5 to 20° C. andis thereafter removed from the decorative layer and, optionally, substrate coating, the decorative element remaining on the substrate coating; andthe substrate coating with the transferred decorative layer is cured completely.
