Definitions

  • the invention relates to a method for producing a printed plastisol or lacquer layer.
  • the US 2016/297223 A1 describes a method for producing a printed lacquer layer, the method comprising providing a carrier material, applying a liquid layer to the carrier material, contactless printing of the liquid layer and curing of the liquid layer. Similar procedures are also in the US 2007/231525 A1 and in the WO 2008/061930 A1 described.
  • Printed plastisol or lacquer layers are used, for example, to produce wall coverings with digitally printed decor or to produce floor coverings. From the WO 2015/140682 A1 It is known to digitally print polymeric supports. A quality criterion for printing is ink anchoring and color homogeneity. Particularly with polymeric carriers, homogeneous surface properties are desired, regardless of the ink used, in order to prevent defects due to local wetting disorders ("island formation"), a lack of abrasion resistance and the resulting color irregularities.
  • a method for inkjet printing on a non-absorbent substrate is from EP 2 249 971 B1 known.
  • Another method for producing a surface coating, in which printing is carried out into a still liquid layer of material before a hardening step, is from the subsequently published EP 3 335 897 A1 known.
  • the polymeric carrier substrates used in many products, such as floor coverings are no longer mechanically stable or no longer process-capable in this temperature range. Examples of these Unsuitable carriers are 50 - 250 ⁇ m thick calendered S-PVC films for the production of luxury Vinyl Tiles (LVT) or PVC/PET films that are used in the decorative sector.
  • the invention is therefore based on the objective object of providing a method in which the quality of the printed image on a flowable layer is maintained throughout the entire manufacturing process.
  • the printed plastisol or lacquer layer can therefore be produced independently of the provision of the carrier substrate, on which the printed plastisol or lacquer layer can be applied, in particular for decorative purposes, in a subsequent process step.
  • the result of this is that the thermal treatment of the plastisol or lacquer layer, in particular a corresponding gelling step, a hardening step or a drying step, takes place without thermal stress on the substrate.
  • the printed plastisol or lacquer layer After the printed plastisol or lacquer layer has hardened, it can be fed inline to a laminating device, where it is laminated onto an optionally temperature-sensitive carrier substrate.
  • the printed plastisol or lacquer layer can be stored on the web-shaped carrier until further processing, for which purpose it is wound onto a take-up spool with the web-shaped carrier, for example.
  • Providing a web-shaped carrier with a release coating and/or a surface with release properties may include providing a release liner or a circulating transfer belt.
  • the release liner or the surrounding transfer belt can have a silicone-containing coating as a release coating.
  • the release coating and/or the surface with separating properties are not limited to any particular embodiments.
  • the release coating does not necessarily have to be a layer separate from the web-shaped carrier.
  • the release coating can be obtained by conditioning the web-shaped carrier with adhesion-reducing materials, for example by siliconizing a carrier fabric tape. What is essential is a non-adhesive or separating property between the surface of the carrier and the plastisol or lacquer layer. For example, stainless steel strips are known that allow a hardened plastisol or lacquer layer to be removed without the application of a separating layer.
  • the contactless printing of the flowable plastisol or lacquer layer can include digital printing, for example inkjet printing or laser printing.
  • the application of a flowable plastisol or lacquer layer can include the application of a solar-type PVC plastisol layer, which is heated to a temperature of preferably more than 130 ° C during hardening, which can involve gelling of the solar-type plastisol layer.
  • an adhesive primer can be applied to the printed and hardened plastisol or lacquer layer and then dried.
  • the adhesive primer can be applied to the side of the plastisol or varnish layer that is printed during printing. It can serve to improve the adhesion of the plastisol or lacquer layer to a clear film or to a wear protection film.
  • the web-shaped carrier with the plastisol or lacquer layer applied thereon can be made available on a take-up reel for later further processing.
  • the printed plastisol or lacquer layer on the web-shaped support can be fed to a laminating device and laminated onto a substrate using the laminating device. Because the substrate is not exposed to the temperatures used to harden the plastisol or lacquer layer, it is possible to control the dimensions of the possibly temperature-sensitive substrate, which is an essential prerequisite for embossing in register, which often follows lamination, for example for the production of floor coverings, such as LVTs.
  • the method may accordingly include embossing the laminate after laminating the cured and printed plastisol or lacquer layer onto a substrate.
  • the plastisol or lacquer layer Before lamination or during lamination, the plastisol or lacquer layer can be detached from the web-shaped support and removed.
  • the web-shaped carrier can remain on the plastisol or lacquer layer and can be laminated to the substrate with the plastisol or lacquer layer as an intermediate layer between the plastisol or lacquer layer and the substrate.
  • Laminating the plastisol or lacquer layer onto the substrate may include laminating the plastisol or lacquer layer onto a clear film and/or onto the substrate of a floor covering.
  • the clear layer can be laminated onto the plastisol or lacquer layer, with the plastisol or lacquer layer being arranged in the laminate produced between the substrate and the clear film.
  • the laminating of the printed plastisol or lacquer layer onto the substrate can be carried out at a temperature of the laminating device of less than 130 ° C and preferably at a temperature of less than 110 ° C with the, for example, thermally plasticized substrate.
  • an ink can be introduced into the flowable plastisol or varnish layer.
  • a sticky property can be used without thermal plasticization, e.g. a hot melt.
  • the printing can, for example, include digital printing.
  • the digital printing can be carried out, for example, as a laser print or as an inkjet print.
  • curing the printed plastisol layer may include gelling the printed plastisol layer, whereby the ink is stabilized in the gelled plastisol layer.
  • a siliconized paper, textile or fabric When providing a web-shaped carrier with a release coating and/or a surface with separating properties, for example, a siliconized paper, textile or fabric can be provided, to which a PVC plastisol is applied during application, which gels or hardens after printing . will be repaid.
  • a web-shaped carrier without a release coating and/or surface with a separating property can be provided, which after printing and curing remains as a partial layer of a multilayer laminate during lamination.
  • a web-shaped carrier 1 with a release coating 2 and/or a surface with separating properties is provided by an unwinding reel 13 in a method step 100.
  • the web-shaped carrier 1 with the release coating 2 and/or the surface with separating properties is fed to a plastisol applicator 14, with the aid of which, in a step 200, a flowable plastisol layer 3 is applied to the release coating 2 and/or the surface with separating properties.
  • the plastisol layer 3 is particularly still flowable and has a solar-like quality when it has not yet been gelled or hardened.
  • the flowable plastisol or lacquer layer 3 After the flowable plastisol or lacquer layer 3 has been applied to the release coating 2 and/or the surface with separating properties of the web-shaped carrier 1 in step 200, it is printed in a non-contact manner in its flowable state in a step 300.
  • ink 9 is introduced into the flowable plastisol layer 3 in digital printing, for example in laser printing or inkjet printing.
  • the printed plastisol layer 3 is hardened.
  • Hardening 400 can include gelling or gelling.
  • a printed and hardened plastisol or lacquer layer 3 can be provided on a web-shaped carrier 1 and, for example, immediately transported inline to a laminating device 6 for further processing or made available offline, for example by placing the printed plastisol or lacquer layer on a take-up reel 5 for stored for further processing.
  • the produced printed and hardened plastisol layer 3 it can be fed on its web-shaped carrier 1 to a laminating device 6, where in a step 600 the web-shaped carrier 1 is detached from the plastisol layer 3 and removed.
  • the web-shaped carrier 1 can be placed on a take-up reel 12.
  • the web-shaped carrier 1 wound onto the take-up reel 12 can be reused later by being reintroduced into the process in step 100.
  • a clear film 8 is fed to the laminating device 6, onto which the printed side of the plastisol layer 3 is applied and then laminated with the plastisol layer 3 onto a substrate 7, so that the plastisol layer 3 is arranged between the clear film 8 and the substrate 7 in the laminate produced .
  • the clear film 8 is optionally heated immediately before application to the plastisol layer 3 in order to improve the adhesion of the clear film 8 to the plastisol layer 3.
  • the substrate 7 supplied to the laminating device 6 is also heated with the preheating device 11, for example an IR radiator, immediately before it comes into contact with the plastisol layer 3, in order to ensure the adhesion of the plastisol layer 3 to the substrate 7 to improve.
  • the laminating device 6 has a heated roller which basically has sufficient heat input onto the clear film 8 and the substrate 7 in order to connect the laminate produced to one another.
  • FIG. 2 The embodiment shown differs from that in Figure 1 embodiment shown in that instead of a web-shaped carrier 1, which is provided via an unwinding reel 13 and picked up again on a take-up reel 12, the web-shaped carrier 1 is provided in the form of a circumferentially closed transfer belt, which, however, is attached to one of the plastisol layer in accordance with the principles of the invention 3 has a release coating 2 and/or a surface with separating properties in order to achieve easy removal of the printed plastisol layer produced on the web-shaped support 1 after hardening 400.
  • a UV varnish applicator 15 is used to apply a UV varnish layer 3 to the web-shaped carrier 1 in step 200. After printing on the UV varnish layer in step 300, the still liquid UV varnish layer is hardened in step 400 by UV irradiation.
  • a step 700 is provided downstream of the hardening 400 and upstream of the lamination 500, in which an adhesive primer 4 is applied to the printed and hardened lacquer layer 3 and dried in a subsequent step 800.
  • the adhesive primer 4 is applied to the printed side of the lacquer layer 3 and is intended to improve the adhesion of the printed lacquer layer 3 to the clear film 8.
  • FIG 4 The embodiment shown differs from that in Figure 1 shown embodiment in that instead of a plastisol applicator, a paint applicator 16 is provided, via which a paint is applied to the release coating 2 and / or the surface with separating properties of the web-shaped carrier 1.
  • this lacquer coating 3 is also used in its still flowable, in particular liquid state, printed in a step 300 by introducing ink 9 and then hardened after printing 300 by drying in a step 400.
  • the varnish can have a water-based or solvent-based base.
