Description

DESCRIPCIÓN DESCRIPTION
Recubrimiento protector para exteriores. tor de la técnica. Outdoor protective coating. tor of technique.
La presente invención se refiere a un recubrimiento protector para exteriores, especialmente adecuado para la protección de objetos galvanizados o de madera, contra el agua, los rayos ultravioleta, productos químicos y el deterioro por el uso The present invention refers to a protective coating for exteriors, especially suitable for the protection of galvanized or wooden objects, against water, ultraviolet rays, chemicals and deterioration due to use.
Estado de la técnica anterior Prior state of the art
En general los objetos de exterior, se deterioran de forma acelerada, al mantenerse expuestos al agua de lluvia, productos químicos, los rayos solares, ambientes salinos y ozaduras o Impactos debido al uso. In general, outdoor objects deteriorate rapidly, when exposed to rainwater, chemicals, sunlight, saline environments and ozaduras or impacts due to use.
Este deterioro se aprecia en mayor medida en objetos de madera y de galvanizado, tales como vías ferratas, marítimas, etc. La protección que se aplica actualmente a este tipo de elementos consiste simplemente en una capa de pintura o de barniz aplicada directamente sobre el material en cuestión o, en el mejor de los casos, sobre una capa previa de selladora o de Imprimación. This deterioration is seen to a greater extent in wooden and galvanized objects, such as via ferrata, maritime, etc. The protection currently applied to this type of element consists simply of a layer of paint or varnish applied directly to the material in question or, in the best of cases, to a previous layer of sealer or primer.
Este po de protecciones se deteriora rápidamente, perdiendo su efectividad, debido a la exposición de los rayos ultravioleta, a la humedad, especialmente en ambientes marinos, y a las rozaduras propias del uso. This type of protection deteriorates rapidly, losing its effectiveness, due to exposure to ultraviolet rays, humidity, especially in marine environments, and scratches typical of use.
Por tanto, el problema técnico que se plantea es el desarrollo de un recubrimiento para exteriores que se pueda aplicar sobre madera o galvanizado y que presente unas características adecuadas para garantizar una correcta protección del objeto en cuestión. Therefore, the technical problem that arises is the development of a coating for exteriors that can be applied on wood or galvanized and that presents adequate characteristics to guarantee a correct protection of the object in question.
Explicación de la Invención El recubrimiento protector para exteriores, objeto de esta Invención, presenta unas particularidades constructivas orientadas a resolver de forma satisfactoria la problemática expuesta; permitiendo una correcta adhesión del mismo, incluso en ambientes húmedos, sobre el objeto a proteger, y proporcionando a dicho objeto una protección adecuada contra diferentes agentes y agresiones externas. Para conseguir los objetivos propuestos este recubrimiento protector está constituido por una lámina multicapa, formada por tres capas de material de diferente naturaleza y con diferentes funciones, superpuestas y unidas entre sí. Concretamente dicha lámina multicapa comprende: Explanation of the Invention The protective coating for exteriors, object of this invention, presents some constructive peculiarities oriented to satisfactorily solve the exposed problem; allowing a correct adhesion of the same, even in humid environments, on the object to be protected, and providing said object an adequate protection against different agents and external aggressions. To achieve the proposed objectives, this protective coating is made up of a multilayer sheet, made up of three layers of material of different nature and with different functions, superimposed and joined together. Specifically, said multilayer sheet comprises:
- una primera capa adhesiva, con una fórmula específica para incrementar tanto su rendimiento como su durabilidad en el tiempo, y adecuada a los materiales a aplicar (madera y hierro) para la fijación del recubrimiento al objeto a proteger. - A first adhesive layer, with a specific formula to increase both its performance and its durability over time, and appropriate to the materials to be applied (wood and iron) for fixing the coating to the object to be protected.
- una segunda capa base, de un material polímero de alta resistencia al agua, a los productos químicos (ácidos, bases y disolventes), a las altas temperaturas, al envejecimiento y a los rayos ultravioleta (UV) y; - a second base layer, made of a polymer material highly resistant to water, chemicals (acids, bases and solvents), high temperatures, aging and ultraviolet (UV) rays and;
- una tercera capa exterior, conformante de la superficie expuesta del recubrimiento, de un material de alta resistencia a la intemperie y al rayado, - a third outer layer, made up of the exposed surface of the coating, of a material with high resistance to weathering and scratching,
La primera capa adhesiva está constituida preferiblemente por poliuretano reactivo (PUR), que es especialmente indicado para la fijación de la lámina multicapa sobre objetos de exterior, ya que dicha primera capa adhesiva produce una reacción química cuando capta humedad del objeto a proteger, al que se va a unir la lámina multicapa, fusionándose con la estructura física de dicho objeto a proteger. The first adhesive layer is preferably made up of reactive polyurethane (PUR), which is especially indicated for fixing the multilayer sheet on outdoor objects, since said first adhesive layer produces a chemical reaction when it captures moisture from the object to be protected, to which the multilayer sheet is to be joined, merging with the physical structure of said object to be protected.
La segunda capa base, está constituida preferentemente por fluoruro de polivinilideno (PVDF) o por policloruro de vinilo (PVC). Esta segunda capa proporciona a la lámina multicapa del recubrimiento protector una elevada resistencia a los productos químicos, a las altas temperaturas, al envejecimiento y a los rayos ultravioleta; lo que le proporciona integridad a la propia lámina y una protección específica al objeto a proteger contra dichos agentes externos. The second base layer is preferably made up of polyvinylidene fluoride (PVDF) or polyvinyl chloride (PVC). This second layer gives the multilayer sheet of the protective coating a high resistance to chemicals, high temperatures, aging and ultraviolet rays; which provides integrity to the sheet itself and a specific protection to the object to protect against said external agents.
La tercera capa exterior de la lámina multicapa conformante del recubrimiento protector es de acrílico transparente o polimetilmetacrilato (PMMA), lo que le proporciona una elevada resistencia a la intemperie, transparencia y resistencia al rayado. La utilización de los materiales mencionados en las sucesivas capas constitutivas de la lámina multicapa, conformante del recubrimiento protector, además de facilitar la su fijación sobre el objeto a proteger por medio de la primera capa adhesiva de poliuretano reactivo (PUR), le proporciona a dicho objeto diferentes tipos de protección, contra el agua, los rayos ultravioleta, los agentes químicos, el envejecimiento, y las posibles rayas o rozaduras producidas habitualmente durante el uso. The third outer layer of the multilayer sheet that makes up the protective coating is made of transparent acrylic or polymethylmethacrylate (PMMA), which provides it with high resistance to weathering, transparency and scratch resistance. The use of the materials mentioned in the successive layers that make up the multilayer sheet, forming the protective coating, in addition to facilitating its fixation on the object to be protected by means of the first reactive polyurethane adhesive layer (PUR), provides said object different types of protection, against water, ultraviolet rays, chemical agents, aging, and possible scratches or scuffs usually produced during use.
