Definitions

  • the invention relates to a method for producing an order Natural malachite stone or malachite-like materials and for Coating objects like a carrier or objects of any kind underneath Achieving the optical effect of a natural malachite stone or malachite-like material.
  • Malachite is a fine crystalline greenish copper carbonate with the formula Cu 3 (OH) 2 CO 3 (RAMDOHR / STRUNZ 1978, p. 578), which due to its grain, growth-related zoning in the form of differently enriched layers, rings and fine lines in the bevel receives typical expression, which can develop the most diverse forms of expression depending on the location and conditions of origin.
  • the invention is therefore based on the object, three-dimensional Objects and foils with natural malachite pigments coat that the typical appearance of the natural malachite rock, both according to its mineralogical inventory and according to whose diverse appearances are reproduced.
  • This Coating should be able to make claims, from the material and from the aesthetic effect as a real, natural malachite coating apply and appear as such on the market.
  • the grain size of the natural malachite mineral after grinding in the Process step a) is to be selected depending on the intended use; best Results with regard to the transparency and brilliance of the order will be given Grain sizes of 10 to 80 microns, preferably 20 to 60 microns, achieved.
  • step b) Parts of dirt cleaned, e.g. the plaster is washed out.
  • the pigment After the production of the malachite pigment, the pigment becomes grain size between 10 and 100 ⁇ m, preferably 20-60 ⁇ m in process step c) colorless binder or an oven-drying or reaction-curing agent Paint systems such as polyesters, polyurethane and acrylic paints based on one or two components, including epoxy and silicone cross-linked Varnishes, dispersed.
  • the pigment content corresponds to 10 to 60 percent of the Parts by weight of the binder, but preferably between 15 and 30 Percent pigment in the binder.
  • the addition of the pigment in sprayable painting systems are possible. Preferably come for that crystal clear brilliant acrylic lacquers for use.
  • the malachite varnish is now preferred in a further process step d) several layers painted onto an object until the desired one Color depth is reached. If necessary, the object was previously primed provided on which the malachite lacquer can adhere. The underground may need to be roughened.
  • the primer is used to the Adapt paint system. The primer itself can be a green one Order to get the desired color depth with a few coats of malachite paint to manufacture.
  • the intermediate drying is used for Strengthening of the lacquer layers, but without the lacquer layers becoming one homogeneous system can be networked. This binding may go with this Not yet done at the time, but only at the end of the procedure, that is if the structural print (step g)) and the top coat (step h)) is applied; then a homogeneous connection of all layers of paint must be by final firing (step i)) and / or drying accordingly the specifications of the paints used are brought about.
  • the It is dried under physical and chemical conditions carried out that did not lead to crosslinking of the paint components chemical level. With stoving lacquer systems, the temperature must be therefore during drying below the reaction temperature of Lacquer reactor are above, however, in the final firing.
  • the applied malachite lacquer layers are air-dried, for example, for about 30 minutes at room temperature; this is preferably followed by a preheating phase of about 10 to 20 minutes at 40 to 80 ° C. Another intermediate drying takes place at 120 ° C for about 10 to 20 minutes or at a lower temperature correspondingly longer.
  • the lacquer layers combine to form a uniform application, but do not yet set, so that the structural print and the top coat can be applied to the surface.
  • a coating with a color and depth effect corresponding to the natural malachite is achieved by two to five layers of malachite lacquer. In order to achieve a deep coloring of the coated object with a very good quality of the coating, more than five layers can also be applied, with drying preferably after 2 to 4 layers.
  • the layers of malachite lacquer can be sprayed on, lacquered on or in some other way the object must be upset.
  • Their thickness is preferably 160 to 180 in each case ⁇ m.
  • the malachite pigment layer produced in this way is made of natural malachite however initially still optically unstructured, i.e. the object is even colored green, and is not yet completely identical in its optical effect the natural malachite stone.
  • the printing ink consists of a burnable clear printing varnish, preferably an acrylic-based screen printing varnish.
  • Epoxy resin must also be used with a compatible ink So no stoving paint because epoxy systems harden without final firing and network.
  • the printing ink contains 2 to 10, preferably 4 percent black mixed color or dispersed black pigment, e.g. Bone black.
  • the ink is preferably transparent to the reproduce different grain nuances by overprinting to be able to.
  • the black ink in step f) about 1 to 15, preferably 2 to 4 percent transparent green dye solution added will.
  • An organic dye is recommended. All details are Percentages by weight.
  • the glazing ink thus produced is printed using structured templates or printing masks at least three, preferably printed four times or varnished, by adjusting the Stencils on the surface structure of natural malachite Malachite rock to be observed in fine light and dark grain an unprecedented fidelity to the original can be reproduced.
  • the Grain i.e. the different light and dark zones of natural malachite is used to produce the printing masks either photographically or removed directly from the stone with the help of a scanner and in different ways light or dark color zones disassembled, which then serve as a template for reproduction be transmitted.
  • the different forms of the natural However, malachits can also be drawn manually and in a variety of ways Transfer color tints to individual films and print them on top of each other will. The colors are preferably produced as line drawings.
  • the malachite structure in process step g) is advantageously reproduced by means of screen printing in several, preferably four, screen printing steps using different screen printing templates.
  • the application of the typical grain can also be simulated by means of offset, foil, gravure, tampon printing using printing templates based on the malachite drawing or by spray painting using appropriate masks.
  • the reproduction of the malachite structure by printing on the glazing transparent printing ink is alternatively carried out before or after coating with malachite lacquer. Even when printed before coating with malachite pigment, the desired grain is ultimately visible, since the malachite lacquer is at least partially transparent. It is only important that ultimately a homogeneous connection of the individual layers is produced by firing or by reaction hardening.
  • one or more, preferably at least ten clear top coats applied e.g. painted or sprayed on.
  • the top coat must be the same as before used paints are compatible. It follows drying and, depending on Paint system, baking the paints, whereby the specifications of the Paint manufacturer must be observed. Connect the different layers of paint become a homogeneous system, with the black pigments of the Also diffuse the ink into the neighboring layers.
  • the inventive method can have the optical effect of the natural Malachits are largely imitated, with the order in principle any objects can be applied. The object is after the Final drying or firing sanded and polished.
  • the method according to the invention has further advantages with regard to health and environmental issues. While processing of natural malachite stone to accessories are usually highly toxic Waste that pollutes the environment and the health of processors highly stress, so that the processing of the malachite raw material problematic worldwide or only possible under high security requirements.
  • the pigment is in a closed system processed and incorporated into the binder, making it easy is processable and recyclable. It doesn't get as with the conventional rock processing as toxic dust particles in the air or into the water.
  • This invention makes malachite natural Unlimited appearance, especially on three-dimensional Products that could not previously be made with natural rock become representable.
  • the process is ideal, a coating made of real Malachite very thin on everyone for the production of luxury goods in question coming parts, e.g. Picture frames, ceramic parts or conical writing instrument sleeves to make an imitation malachite from real malachite mineral to manufacture.
  • items that are not currently can be refined with malachite stone, with the corresponding Coating to achieve the optical effect of real malchits be upgraded.
  • the pen sleeves are ground and oven-hardened one-component polyurethane paint as a primer that the This results in a primer and pre-dried at 80 degrees and at 140 degrees is branded.
  • Real malachite pigment is between 10 and 60%, preferably 25% Percentages by weight of binder dispersed in acrylic paint.
  • the grain sizes are between 25 and 30 ⁇ m; the paint is sprayable with a flow viscosity of 15 sec.
  • This paint is placed in a paint cup on which Lid is a motor or air-powered agitator, which the specifically heavier malachite pigment constantly during the painting process hovers in order not to clog the spray nozzle.
  • the Malachite pigment is coated twice on the primer. After that they are burned in at 80 and 120 degrees for fifteen minutes each.
  • the conical writing instrument sleeves are on a cylindrical grinding machine ground to break the remaining pigment tips.
  • the pen sleeves prepared in this way are placed on a guide pin put on. Then they are used several times with a rotary screen printing machine in this case four times, with the previously described transparent color Acrylic paint using the one on top of the other shown in Figure 1a to d coordinated motifs with a pattern of different widths, in Stripes running in the direction of the sleeve are printed using the screen printing process.
  • the print is pre-dried and burned and then varnished with clear varnish in ten layers of varnish.
  • the special of this process is that in the final baking of the total eighteen different screen printing and varnish layers of the transparent Dye diffuses with the black into the upper layers of paint, whereby a three-dimensionality (depth) of the malachite coating is achieved that is impossible with normal printing processes and thus a new one State of the art of reproduction for natural malachite.
  • Figure 1 a to d shows one Printing stencil, consisting of a black stripe pattern with stripes, the width similar within a template, from template to template vary in width. The stencils are successively printed on.
