Definitions
- the subject of the invention is surface treatment of a polymer wall or facade panel with digital print.
- Decorative material that comprises: a substrate; a print layer provided on the substrate; a protective layer provided on the print layer is known from the American description US2003113520 (A1 ), where the protective layer comprises an ionizing radiation-cured resin; and a primer layer provided between the print layer and the protective layer, for relaxing shrinkage stress caused at the time of curing of an ionizing radiation-curable resin for the formation of the ionizing radiation-cured resin constituting the protective layer.
- a method of applying decorative inkjet prints to the surface of base materials is known from the Japanese description JP2008265229 , where the print is applied to a layer of flexible resin and then covered with a hard protective layer.
- a method of coating a building panel with a UV curable layer using a digital print head is known from the patent description WO2014011110 (A1 ), where the surface is cured afterwards to form a transparent protective surface layer.
- a method of producing building panels is known from another description - US2014144583 (A1 ) - where digital print is applied in a separate production cycle to a media layer (e.g. film) and then heat and pressure is applied to form a panel with a protective layer.
- a media layer e.g. film
- a method of producing a substrate for directly printed decorative panels is known from description WO2016124433 , where several layers of resin compositions - consisting of melamine resin and urea resin - are applied to the panel, following which the panel is dried.
- US2016303867 discloses a method of producing a decorative outer layer by which digital print is applied directly to the panel and before the print is applied the panel surface is primed or sanded.
- the most important problem is the pre-treatment of the panel core. This is due to the fact that the basic problem of printing on PVC profiles or panels using pigmented acrylic resin-based inks is the very low porosity of plastic surfaces, which leads to virtually negligible ink penetration into the substrate. Another important problem is the issue of inadequate surface tension of inks and varnishes as well as low free surface energy of the panel, resulting in the lack of satisfactory print resolution.
- the essence of the inventive work was to find an optimum solution for permanent connection of the printed layer with the printed surface. This effect was achieved by using the right composition of the primer and adjusting the process to the requirements of its use.
- the essence of the invention is the method of surface treatment of a polymer wall or facade panel with digital print.
- the surface of an extruded polymer wall or facade panel is cleaned mechanically - for example with brushes or air stream - and afterwards with organic solvent or a mixture of organic solvents (hydrocarbons, alcohols, ketones, esters) with boiling temperatures in the range of 50 - 140 °C, preferably 70 - 100 °C, preferably based on ethyl acetate, butyl acetate, ethanol, isopropanol and/or methyl ethyl ketone.
- the aim is to clean the surface from dirt generated during the production process, e.g. waxes, lubricants.
- a layer of primer based on polymer resins is applied - preferably acrylic, with photoinitiators - in the amount of 5 - 30 g/m2, preferably 10 - 20 g/m2.
- the primer is cured with mercury, gallium or iron lamps with a power of 80 - 140 W/cm, preferably 100-120 W/cm, for no more than 3 s.
- digital print is applied to such a surface using industrial oil-based inks or UV-cured inks containing organic and/or inorganic pigments.
- Varnish based on polymer resins - preferably acrylic resins, with photoinitiators - is then applied to the printed surface in the amount of 5 - 30 g/m2, preferably 10 - 20 g/m2.
- the protective varnish layer is cured with mercury, gallium or iron lamps with a power of 80 -140 W/cm, preferably 100-120 W/cm, for no more than 3 s.
- the invention is illustrated by the following embodiment.
- the surface of an extruded polymer wall panel was cleaned mechanically with brushes and pressured air, followed by a mixture of solvents based on butyl and ethyl acetate with a boiling temperature of 85°C. Next, electrical charges were removed from the cleaned surface using deionization strips.
- the product created according to the invention can be used in any room, both indoors and outdoors. It is characterized by reduced weight compared with competitive products (e.g. ceramic tiles).
- the panel is resistant to impacts and other mechanical damage, and improves acoustic insulation properties of a given room. Moreover, such panels are moisture and water resistant.
- the digital printer used in the process has a modular structure that allows an image of any size to be arranged either vertically or horizontally. The print can be applied on textured surfaces. The materials to be printed (patterns) are submitted to the printing device as digital data. This ensures precise control of coating thickness and allows for printing high-resolution colour graphics from 320 dpi, using CMYK colour modules.
