Description

DESCRIPCIÓNDESCRIPTION

Recubrimiento protector para exteriores.Protective coating for outdoors.

Sector de la técnica.Technical sector

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 usoThe present invention relates to an outdoor protective coating, especially suitable for the protection of galvanized or wooden objects, against water, ultraviolet rays, chemicals and deterioration due to use.

Estado de la técnica anteriorPrior 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 a rozaduras o impactos debido al uso.In general, outdoor objects deteriorate rapidly, by being exposed to rainwater, chemicals, sunlight, saline environments and chafing 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.This deterioration is seen to a greater extent in objects of wood and galvanized, such as via ferrata, sea, 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.The protection that is currently applied to this type of elements consists simply of a layer of paint or varnish applied directly on the material in question or, in the best case, on a previous layer of sealant or primer.

Este tipo 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 the exposure of ultraviolet rays, to humidity, especially in marine environments, and to the scratches typical of the 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 an exterior coating that can be applied on wood or galvanized and that has adequate characteristics to ensure proper protection of the object in question.

Explicación de la invenciónExplanation of the invention.

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.The protective exterior coating, object of this invention, has some constructive particularities oriented to satisfactorily solve the exposed problem; allowing proper adhesion of it, even in humid environments, on the object to be protected, and providing said object with adequate protection against different agents and external aggressions.

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:To achieve the proposed objectives, this protective coating is constituted by a multilayer sheet, formed by 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, of a polymer material of high resistance to water, chemical products (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, forming the exposed surface of the coating, of a material of high weather and scratch resistance,

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 preferably consists of reactive polyurethane (PUR), which is especially suitable 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 going 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 polyvinylidene fluoride (PVDF) or polyvinyl chloride (PVC). This second layer provides the multilayer sheet of the protective coating with 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 be protected 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.The third outer layer of the multilayer sheet forming the protective coating It is made of transparent acrylic or polymethylmethacrylate (PMMA), which gives it high weather resistance, transparency and scratch resistance.

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 use of the materials mentioned in the successive layers constituting 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 (PUR) adhesive layer, provides said object different types of protection, against water, ultraviolet rays, chemical agents, aging, and possible scratches or chafing usually produced during use.
