Definitions
- the present invention consists of a process for the decoration of metal parts in general, and preferably of aluminum or iron profiles to which it is desired to apply a decorative layer imitating a natural finish such as marble, wood etc.
- the present invention has application in the field of decoration of metal parts, and in particular in the decoration of aluminum or iron profiles by applying powder paints.
- polyester powder paints with a distribution of the particle size of the powder that depends on each manufacturer, but which is conventionally between 40 and 150 microns.
- the size of the powdered particles has a direct influence on the electrostatic deposition of the paint.
- the metal part for example in a change of position of the piece to apply paint on another of its faces, so during that manipulation the particles of very small particle size suffer displacements that disfigure the decorative motif and reduce the quality of the final result.
- the decoration procedure developed in the present invention satisfactorily solves the shortcomings of the procedures known at present, since it allows the decoration of metal parts with a high degree of precision in the reproduction of decorative designs, and therefore provides a finishing of a quality far superior to the decoration procedures known in the state of the art.
- the process object of the invention starts from a first conventional phase, in which a first paint based on polyester powder is electrostatically deposited on a metal piece to be decorated, such as for example a piece of aluminum or iron. Similarly in conventional manner, this first powder paint is subjected to a heat treatment.
- the novelty of the invention lies in the application by screen printing of a second powder paint with a particle size of less than 40 microns, contrary to the usual practice in these techniques, and all this with in order to achieve a very high definition in the reproduction of the decorative motif thanks to the use of a very fine powder. In this way it is possible to reproduce details, such as wood grain, for example, with an accuracy that would not be possible with the procedures known today.
- this second powder paint with a selected particle size is subjected to a heat treatment in localized areas to fix it on the first paint.
- the heat treatment consists in the application of a radiation, preferably an infrared radiation, in order to heat the second paint until it reaches a gelatinous state that produces its fixation on the first layer of base paint, and thus allows the manipulation of the metal piece to decorate without risk that the particles of the second paint move and the decorative design is disfigured.
- the metal part with the first base paint and the second paint is subjected to a final and joint final treatment with which the first and second coat of paint is polymerized together obtaining the final decoration of the product.
- the process object of the invention thus achieves levels of definition in the reproduction of a decorative motif, far superior to those achieved by conventional decoration techniques.
- Figure 1 schematically represents the elliptical reflector preferably used in the heat treatment of the second paint participating in the process.
- the decoration procedure object of the present invention comprises the following phases:
- this second paint is carried out using a screen printing mesh of 40 microns of mesh passage, and the particles of this second powder paint are selected with a size less than 40 microns, since particles of a larger size would not pass through the mesh and clog the pores thereof, thus losing definition in the reproduction of the motif decorative.
- the particle size of this second paint is between 5 and 30 microns.
- a heat treatment is carried out located in the areas (A) where said second paint has been deposited, so that it acquires a gelatinous state that allows its fixation on the first base paint.
- This heat treatment consists in the application of an infrared radiation with a short wave with its maximum energy located between 1000 and 1200 nm, being concentrated and directed by an elliptical reflector (2), with which according to the arrangement shown in Figure 1, the maximum radiation concentration is obtained at a distance (C) between 10 and 30 mm from the metal surface (1). In a preferred embodiment this distance is between 15 to 17 mm.
- the short wave is obtained by a quartz lamp working at 2400 ° C, and the maximum radiation application time is between 1 to 10 seconds, preferably between 2 to 4 seconds. With these working parameters it is achieved that the time necessary to complete this heat treatment by application of infrared radiation is considerably short, and therefore does not influence the total time in which the decoration of a metal part is completed.
- infrared radiation so located in the areas where the second paint has been applied, its purpose is not to affect the first base paint, so that the state reached by this base paint is not altered during its heat treatment described in point 2.
- This second paint may have a different hue or color than the first base paint, in order to obtain the desired decorative design.
- the metal part to be treated can be manipulated, for example its position can be changed to apply paint on another of its faces, without the risk that the particles of the second paint applied by screen printing move from the exact point at which They have been deposited using screen printing mesh.
