EXPLICACION DE LA INVENCIONEXPLANATION OF THE INVENTION
El procedimiento para la fabricacion de placas reflexivas que la presente invencion propone se configura, pues, como una novedad dentro de su campo de aplicacion, estando los detalles caracterizadores del mismo convenientemente recogidos en las reivindicaciones finales que acompanan a la presente memoria descriptiva del mismo.The procedure for the manufacture of reflective plates that the present invention proposes is thus configured as a novelty within its field of application, the characterizing details thereof being conveniently included in the final claims that accompany this descriptive specification thereof.
De forma concreta, lo que la invencion propone es, como ya se ha apuntado anteriormente, un nuevo procedimiento para la fabricacion de placas de matricula o de serialization, cuya finalidad es transformar en reflexiva la placa base de la que se parte para obtener la placa de matricula, bien sea metalica o plastica, aplicando a la misma microesferas reflectivas.Specifically, what the invention proposes is, as already noted above, a new procedure for the manufacture of license plate or serialization plates, whose purpose is to reflectively reflect the base plate from which it is split to obtain the plate of registration, either metallic or plastic, applying to the same reflective microspheres.
Como es conocido, las microesferas reflectivas son un polvillo de esferas de cristal diminutas que tienen apenas una micras de diametro y que, aplicadas sobre una superficie, normalmente mezcladas con una pintura, proporcionan a la misma propiedades reflectantes de la luz.As is known, the reflective microspheres are a powder of tiny glass spheres that are barely a micron in diameter and that, applied on a surface, normally mixed with a paint, provide the same reflective properties of light.
Asi, a traves del presente procedimiento, se aplica dicho tipo de microesferas para la transformation de las placas en placas reflectantes.Thus, through this procedure, said type of microspheres is applied for the transformation of the plates into reflective plates.
En concreto, el procedimiento preconizado contempla las siguientes etapas de fabricacion:Specifically, the recommended procedure contemplates the following manufacturing stages:
- sobre una placa base metalica, de grosor variable, se aplica una capa de barniz transparente;- a transparent varnish layer is applied to a metal base plate of varying thickness;
- sobre dicha capa de barniz transparente, y antes de su secado, se aplica, mediante tecnica apropiada, por ejemplo pulverizado con pistola, una capa de microesferas reflectivas, las cuales quedan fijadas a la capa de barniz; y finalmente,- on said transparent varnish layer, and prior to drying, a reflective microsphere layer, which is fixed to the varnish layer, is applied by appropriate technique, for example spray gunning; and finally,
- sobre la capa de microesferas reflectivas, se aplica una capa cobertora y de protection transparente.- over the layer of reflective microspheres, a cover and transparent protection layer is applied.
Conviene senalar que la placa base, que como se ha senalado anteriormente es metalica, en una primera option de realization, es una placa sin pintar, para ser pintada y embutida posteriormente, una vez confeccionada la placa y transformada en reflexiva. En esta opcionIt should be noted that the base plate, which as noted above is metallic, in a first option of realization, is an unpainted plate, to be painted and embedded later, once the plate is made and transformed into reflective. In this option

de realization, ademas, la capa cobertora de protection que se aplica sobre la capa de microesferas es, o bien una nueva capa de barniz transparente, o bien una fina lamina transparente y flexible de material plastico, por ejemplo de poliester, de pocas micras de grosor.In addition, in addition, the protective covering layer that is applied to the microsphere layer is either a new transparent varnish layer, or a thin transparent and flexible sheet of plastic material, for example polyester, a few microns in size. thickness.
En una variante alternativa de realizacion, la placa base metalica va pintada en algun color, bien por toda la superficie de una de sus caras (la que queda vista), o bien solo parcialmente. En este caso, ademas, sobre la citada placa base, y previamente a la incorporation del barniz transparente que fija las microesferas reflectivas, se incorpora una lamina metalica (tipo solid foil) de mmimo grosor (entre 14 y 20 micras) que esta provista de adhesivo en la cara que se fija a la placa base. Luego, sobre dicha lamina metalica, se aplica la capa de barniz transparente y, antes de su secado, se aplica la capa de microesferas reflectivas y, finalmente, sobre la capa de microesferas reflectivas, se aplica la capa cobertora y de proteccion transparente, que en este caso tambien es, o bien una nueva capa de barniz transparente, o bien una fina lamina transparente y flexible, preferentemente de poliester. En esta option de realizacion, la placa, una vez confeccionada y transformada en reflexiva, se puede someter a un proceso de embuticion y troquelado, permitiendo eliminar de la misma las partes que interese, para formar los signos alfanumericos que correspondan, gracias a la existencia de la citada lamina metalica adhesivada.In an alternative embodiment, the metal base plate is painted in some color, either over the entire surface of one of its faces (the one that remains visible), or only partially. In this case, in addition, on the aforementioned base plate, and prior to the incorporation of the transparent varnish that fixes the reflective microspheres, a metallic foil (solid foil type) of mmimo thickness (between 14 and 20 microns) is incorporated that is provided with adhesive on the face that attaches to the motherboard. Then, on said metal sheet, the transparent varnish layer is applied and, before drying, the reflective microsphere layer is applied and, finally, on the reflective microsphere layer, the transparent protective cover layer is applied, which in this case it is also a new layer of transparent varnish, or a thin transparent and flexible sheet, preferably polyester. In this option of realization, the plate, once made and transformed into reflective, can be subjected to a process of drawing and punching, allowing to eliminate from it the parts that interest, to form the corresponding alphanumeric signs, thanks to the existence of said adhesive metallic sheet.
Finalmente, en una tercera opcion de realizacion, la placa base metalica va ya pintada con los signos alfanumericos que corresponda y, tras la incorporacion de la capa de barniz transparente y la capa de microesferas reflectivas incorporadas antes del secado de esta, incorpora, como capa cobertora y de proteccion una pieza de material plastico transparente de espesor considerable, entre 1 y 10 mm., preferentemente una pieza semirigida de material plastico acrilico.Finally, in a third embodiment, the metal base plate is already painted with the corresponding alphanumeric signs and, after the incorporation of the transparent varnish layer and the reflective microsphere layer incorporated before drying it, incorporates, as a layer cover and protection a piece of transparent plastic material of considerable thickness, between 1 and 10 mm., preferably a semi-rigid piece of acrylic plastic material.
El descrito procedimiento para la fabrication de placas reflexivas representa, pues, una innovation de caracteristicas estructurales y constitutivas desconocidas hasta ahora para el fin a que se destina, razones que unidas a su utilidad practica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita.The described procedure for the manufacture of reflective plates represents, therefore, an innovation of structural and constitutive characteristics unknown until now for the purpose to which it is intended, reasons that together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that is requested.
