Definitions

  • the invention relates to a method for decorating an object.
  • the material of the item in particular come in Consider wood or wood-based materials. But the procedure can also for decorating objects made of plastic, metal, ceramics, Serve textiles or leather.
  • the decoration is made with dyes that represent a motif or can also be used in one color.
  • the inventive method for decorating furniture or Suitable for furniture parts is the inventive method for decorating furniture or Suitable for furniture parts.
  • EP 0 573 676 A1 describes the use of a carrier "Release" property for applying color decor to a Substrate.
  • This state of the art is used for this purpose first the color decor on a carrier with "release” property applied, then over the color decor applied to the carrier a varnish is applied, the varnish is then partially cross-linked and then under pressure and / or elevated temperature of the partially crosslinked Lacquer together with the color decor from the wearer towards the end decorating substrate so transferred that the paint under the Color decor rests on the substrate. Finally there a further crosslinking of the lacquer on the substrate.
  • PVC films have mechanical properties good for coating everyday items such as z. B. furniture are suitable.
  • the objects should be colored be decorated, e.g. B. in the manner of a wood pattern or the like, PVC has the disadvantage that it is difficult to print is.
  • the use of foils also leads to the coating of Articles according to the prior art do not become an aesthetic appealing decoration.
  • the object of the invention is to provide a method with objects can be coated with a film that a both in terms of the mechanical stability of the decoration as well as their aesthetic effect becomes.
  • polyolefin film is included in the sense of this application generally polyolefins, copolymeric polyolefins and also mixtures it.
  • a particularly preferred example of a copolymer Polyolefins for use in the present invention is that So-called ESI from DOW Chemical, d. H. an ethylene-styrene interpolymer, which is offered under the name ESI. It has the following in particular for the purposes provided here advantageous properties: it sticks under pressure and temperature, is easily deformable, can be easily with the so-called "release” technique decorate, and is easy to paint.
  • a polyolefin film is only with conventional printing techniques badly printable. According to a preferred embodiment of the Invention is therefore provided that the decor from a carrier with "release” property is transferred to the slide before then the film onto the object in the manner described above is applied and heated.
  • Carriers with "release” properties are known as such (cf. EP 0 573 676 A1).
  • certain papers are particularly considered or also plastic films that are designed on their surface or are prepared that applied under certain conditions Layers of paint or varnish in the manner of a "Peeling" (like a decal) on an object or a Are transferable.
  • a carrier with "release” property plastic films into consideration, such as in particular polyester films.
  • peeling off is also suitable Release layers known for the film with "release” property.
  • a primer layer is applied in step b) under the decor on the object comes to rest.
  • the primer layer enables the object to be primed, which is particularly effective for wood and wood-based materials comes. At the same time, the primer creates a mechanical and thermally strong connection between the object and the Foil. This is according to a preferred embodiment of the invention provided that the primer layer had adhesive property Has.
  • the adhesive property of the primer layer can be according to one preferred embodiment are produced by a hot melt adhesive, which develops its adhesive properties at elevated temperatures.
  • the primer layer has thermoplastic properties. This is particularly suitable for firm, full-surface adhesion of the Foil on the object.
  • the primer layer contains a base color that is suitable for the Overall decoration is effective. Should z. B. decorated the item be able to convey the impression of wood the basic color corresponds to the wood color and the one placed on it Decorating with the PVC film complements this basic color Subtleties of the wood structure, such as grain etc.
  • the film is preferably clear, i. H. transparent.
  • the above steps b) and c) can preferably essentially are executed overlapping in time, d. H. a thing is covered with heating with the decorated film, especially encased on all sides.
  • the warming is preferably carried out at temperatures in the range from 120 ° C. to 250 ° C, particularly preferably at temperatures in the range of 160 ° C up to 190 ° C.
  • a varnish is applied to the film.
  • the paint is preferably curable by means of an electron beam.
  • the invention is preferably provided that the above explained primer layer can be activated by electron beam is, e.g. B. in terms of their adhesive properties. Leg hardening the varnish combines with the polyolefin using an electron beam (so-called "graft polymerization).
  • Figure 1 shows a film 10 made of ESI (see above).
  • a decor 12 made of diffusible dye molecules On the slide 10 is a decor 12 made of diffusible dye molecules applied.
  • the color decor 12 is in particular by means of the input explained "release” technique applied to the film 10. Since the film 10 made of ESI is not readily compatible with the diffusible Dyes are printable, the colored decor first on a carrier (not shown) with "release” property printed.
  • a carrier with “release” property a polyester film is particularly suitable.
  • the primer layer 14 later causes the primer to be decorated Item 16 ( Figure 2).
  • As a material for the primer layer 14 come into consideration in particular hot melt adhesive, Thermoplastics and adhesive films.
  • the primer layer 14 can contain a base color with which the object 16 is colored shall be.
  • the one provided with the color decor 12 and the primer layer 14 1 is to be decorated according to FIG Item 16 placed. Warming to the specified Temperatures are wrapped around the object 16, the film 10 is on top. Diffuse due to warming the dye molecules in the film and produce the above Color impression. Furthermore, the heating causes a mechanical stable, full-surface bonding of all system components.
  • the heating can be done with IR radiation or otherwise.
  • IR radiation E.g. can be used for heating and also for mechanical sheathing the object 16
  • a so-called “hot air knife” can be used.
  • a “hot air knife” is a hot air jet in the form of a narrow strip that over the film with the one below Object is guided so that the film on all sides to the Object nestles and is heated at the same time.
  • a lacquer 18 can be applied over the film 10 become.
  • An electron beam curable lacquer is preferred used.
  • Electron beam hardening (ESH) is then carried out So-called graft polymerization of the lacquer with the polyolefin. there can also be chosen so that the base layer 14 by the electron beam can be activated, d. H. their adhesive properties unfolded.
