STATE OF THE TECHNIQUE. -
Es conocido la existencia en el actual estado de la técnica de procedimientos, métodos y composiciones para revestimiento en construcción en las que el caucho sintético juega un papel importante, debido sin duda a sus buenas características de material elástico, adherente y, en estado sólido, resistente a la abrasión. De hecho, hay algunas patentes publicadas relativas a este tipo de aislamiento. Por ejemplo, la patente con número de publicación ES8707988A1 describe un método para fabricar una estructura revestida con una composición polímera antiincrustante que contiene caucho de silicona vulcanizado, especialmente pensada para la protección submarina. Por otro lado, la patente ES2092434B1 trata sobre un procedimiento para la impermeabilización de superficies en el que el compuesto impermeabilizante está formado por la mezcla de una emulsión asfáltica a base de betún, y una emulsión de látex a base de caucho. También puede citarse como ejemplo del estado de la técnica el documento de patente con número de publicación ES2082573T3, que versa sobre el empleo de masas de recubrimiento a base de polimetilmetacrilato para la consecución de una estructura superficial rugosa, en el que se describen diversas mezclas de metacrilato polimerizado junto con caucho para aislamiento y revestimiento . Debido a dichas buenas propiedades del caucho sintético es por lo que se ha considerado a este elastómero como componente base del nuevo revestimiento desarrollado para la construcción. Se ha elegido el caucho sintético en estado liquido como materia prima para obtener una pasta fluida que permita aplicar un recubrimiento continuo sobre las superficies, en forma de una capa uniforme, sin juntas ni solapes, bien por proyectado mecánico o con llana tradicional, y se ha seleccionado a la perlita expandida, el poliuretano expandido y la fibra blanca en hilos como componentes adicionales que mejoran las características de adherencia, resistencia e impermeabilidad de un producto de por si ya muy elástico, y que le confieren capacidad aislante, en unas proporciones adecuadas resultado de diferentes ensayos que garantizan unas características óptimas de aplicabilidad del producto fluido y, una vez suficientemente seco, de calidad y durabilidad en las obras. It is known the existence in the current state of the art of procedures, methods and compositions for coating in construction in which synthetic rubber plays an important role, due undoubtedly to its good characteristics of elastic, adherent material and, in solid state, abrasion resistant In fact, there are some published patents related to this type of insulation. For example, the patent with publication number ES8707988A1 describes a method for manufacturing a structure coated with an antifouling polymer composition containing vulcanized silicone rubber, especially intended for underwater protection. On the other hand, the ES2092434B1 patent deals with a process for surface waterproofing in which the waterproofing compound is formed by mixing a bitumen-based asphalt emulsion and a rubber-based latex emulsion. The patent document with publication number ES2082573T3 can also be cited as an example of the state of the art, which deals with the use of polymethylmethacrylate-based coating masses for achieving a rough surface structure, in which various mixtures of polymerized methacrylate together with rubber for insulation and coating. Due to these good properties of synthetic rubber, this elastomer has been considered as the base component of the new coating developed for construction. The rubber has been chosen Synthetic in liquid state as raw material to obtain a fluid paste that allows to apply a continuous coating on the surfaces, in the form of a uniform layer, without joints or overlaps, either by mechanical projection or with traditional trowel, and the pearlite has been selected expanded, expanded polyurethane and white fiber in threads as additional components that improve the characteristics of adhesion, resistance and impermeability of a product already very elastic, and that give it insulating capacity, in adequate proportions result of different tests that guarantee optimum characteristics of fluid product applicability and, once sufficiently dry, of quality and durability in the works.
No se conoce hasta ahora un revestimiento continuo a base de caucho sintético con unos componentes y prestaciones como el desarrollado. La investigación realizada en el estado de la técnica a través de búsquedas en bases de datos de patentes de la OEPM ha dado el resultado arriba comentado, de la existencia de algunas composiciones de revestimiento utilizando caucho, pero ninguna anticipando los componentes principales del producto en cuestión. Consultas de bibliografía no patente a través de Internet han dado igualmente resultado negativo, por lo que el referido producto se considera de invención . COMPENDIO DE LA INVENCIÓN. - It is not known until now a continuous coating based on synthetic rubber with components and features like the one developed. The investigation carried out in the state of the art through searches in SPTO patent databases has given the result mentioned above, of the existence of some coating compositions using rubber, but none anticipating the main components of the product in question . Consultations of non-patent literature through the Internet have also given negative results, so that the referred product is considered of invention. SUMMARY OF THE INVENTION -
Entrando en detalles, el revestimiento continuo de altas prestaciones para la construcción que se reivindica de invención, y que como todo revestimiento continuo permite cubrir uniformemente, sin juntas ni solapes, la superficie de fachadas, suelos y cubiertas sobre las que se aplica, está constituido a partir de una mezcla homogénea formada por 91-94% en peso de caucho sintético liquido, con aditivos y pigmentos de alta resistencia para conferirle determinada textura y color, antiespumante y antidescolgante, 3-5% de perlita expandida, 2-4 % de poliuretano expandido triturado en forma de serrín, y 0,2- 0,5% de fibra blanca en hilos cortos. Entering details, the high performance continuous coating for the construction claimed of invention, and that as any continuous coating allows to cover uniformly, without joints or overlaps, the surface of facades, floors and roofs on which it is applied, is constituted from a homogeneous mixture formed by 91-94% by weight of rubber Synthetic liquid, with additives and pigments of high resistance to confer certain texture and color, antifoam and non-pendant, 3-5% expanded perlite, 2-4% crushed expanded sawdust polyurethane, and 0.2-0.5 % white fiber in short threads.
En una realización preferente, el revestimiento presenta una composición por litro de caucho sintético, de 34 gr de perlita expandida, 23 gr de poliuretano expandido y 4 gr de fibra blanca en hilos. In a preferred embodiment, the coating has a composition per liter of synthetic rubber, 34 grams of expanded perlite, 23 grams of expanded polyurethane and 4 grams of white fiber in threads.
El producto así resultante se presenta en forma de masa fluida envasada en cubos herméticamente cerrados, preparada para proyectar por medios mecánicos, como manguera o pistola, o aplicar manualmente con llana o herramienta similar. The resulting product is presented in the form of a fluid mass packed in hermetically sealed cubes, prepared to project by mechanical means, such as a hose or gun, or manually applied with a trowel or similar tool.
El producto, una vez aplicado y seco, puede ser sometido a operaciones de lijado y raspado para dejarlo totalmente liso, o semejante al monocapa tradicional, pudiéndosele aplicar posteriormente dos manos finas del mismo material con el color elegido. The product, once applied and dried, can be subjected to sanding and scraping operations to leave it completely smooth, or similar to the traditional monolayer, being able to subsequently apply two thin hands of the same material with the chosen color.
Se tiene por tanto, un nuevo revestimiento continuo para la construcción, para ser aplicado a todas las superficies de los edificios en forma de una capa uniforme, cuya ventaja principal estriba en conseguir mediante un solo producto, barato y ecológico, dado lo económico de sus componentes, unas excelentes prestaciones de elasticidad, adherencia, resistencia, impermeabilidad y aislamiento térmico y acústico, lo cual redunda en versatilidad de aplicación, durabilidad, mantenimiento de los edificios y confort en su interior. There is therefore a new continuous coating for the construction, to be applied to all the surfaces of the buildings in the form of a uniform layer, whose main advantage is to obtain by means of a single product, cheap and ecological, given the economic of its components, excellent performance of elasticity, adhesion, resistance, impermeability and thermal and acoustic insulation, which results in versatility of application, durability, maintenance of buildings and comfort inside.
Estas importantes ventajas que aporta el nuevo revestimiento derivan de las características cualitativas y cuantitativas de sus componentes. These important advantages of the new coating derive from the qualitative and quantitative characteristics of its components.
En primer lugar, y como elemento principal de la mezcla a partir de la cual se forma, se encuentra el caucho sintético. Este tipo de caucho, sustitutivo del caucho natural cuando se requieren propiedades mejoradas de elasticidad de los materiales, es un elastómero, que tiene la propiedad mecánica de poder sufrir mucha más deformación elástica bajo estrés que la mayoría de los materiales y aun así regresar a su tamaño previo sin deformación permanente. En el caso concreto del caucho sintético líquido, se presenta en forma de pasta fluida de muy fácil aplicación, que al secarse o curarse da como resultado una membrana elástica de alta resistencia, sin juntas ni solapas. Dicha membrana no se disuelve en agua, lo que garantiza la impermeabilización de la superficie sobre la que se aplique. Además, el caucho líquido presenta una gran adherencia, pudiendo aplicarse sobre casi todas las superficies de construcción, ya sean terrazas, muros de hormigón, revocos, yeso, ladrillo normal y ladrillo cara-vista, cerámica barnizada, terracota, piedra, tejas, pizarras, hierro galvanizado, aceros inoxidables, aluminio lacado, P.V.C., etc. Por todo ello, es al caucho sintético líquido utilizado como componente base del producto, al que se deben sus propiedades de revestimiento continuo elástico, adherente e impermeable. First, and as the main element of the mixture from which it is formed, is synthetic rubber. This type of rubber, a substitute for natural rubber when improved elasticity properties of materials are required, is an elastomer, which has the mechanical property of being able to suffer much more elastic deformation under stress than most materials and still return to its previous size without permanent deformation. In the specific case of liquid synthetic rubber, it is presented in the form of a fluid paste of very easy application, which when dried or cured results in an elastic membrane of high resistance, without joints or flaps. This membrane does not dissolve in water, which guarantees the waterproofing of the surface on which it is applied. In addition, liquid rubber has great adhesion, being able to be applied on almost all construction surfaces, whether terraces, concrete walls, plaster, plaster, normal brick and face brick, varnished ceramic, terracotta, stone, tiles, slate , galvanized iron, stainless steels, lacquered aluminum, PVC, etc. Therefore, it is the liquid synthetic rubber used as the base component of the product, to which its Continuous elastic, adherent and waterproof coating properties.
El segundo elemento en porcentaje es la perlita expandida. Este es un material cerámico muy utilizado en construcción por su peso liviano, ya que contiene grandes cantidades de aire en su interior, y por sus excelentes características como aislante térmico y acústico, de ahí que sea el componente que confiera al revestimiento propiedades aislantes. The second element in percentage is the expanded perlite. This is a ceramic material widely used in construction because of its light weight, as it contains large amounts of air inside, and for its excellent characteristics as thermal and acoustic insulation, hence it is the component that gives the coating insulating properties.
En tercer lugar se encuentra el poliuretano expandido. El poliuretano es un polímero bien conocido que presenta excelentes características para aislamiento en construcción. Entre algunas de las más interesantes cabe destacar su total adherencia a todo tipo de superficies, su baja conductividad térmica debido a su composición físico-mecánica, su resistencia al ataque de ácidos, álcalis y microrganismos y su no porosidad, lo que impide el paso del agua a través de él. Por ello, una pequeña adición de poliuretano expandido triturado, a modo de serrín, en la cantidad definida, mejora el aislamiento, resistencia, impermeabilidad y adherencia del revestimiento . Third is expanded polyurethane. Polyurethane is a well known polymer that has excellent characteristics for construction insulation. Among some of the most interesting are its total adhesion to all types of surfaces, its low thermal conductivity due to its physical-mechanical composition, its resistance to the attack of acids, alkalis and microorganisms and its non-porosity, which prevents the passage of Water through it. Therefore, a small addition of crushed expanded polyurethane, as a sawdust, in the defined quantity, improves the insulation, strength, impermeability and adhesion of the coating.
Por último, también es importante la pequeña proporción de fibra blanca en forma de hilos cortos añadida, cuya principal función es actuar como material de refuerzo, ya que durante el proceso de curado constituyen una armadura tridimensional y homogénea en toda la masa de material, proporcionándole una mayor resistencia a esfuerzos mecánicos de flexión, tracción o corte, mejorándose así la resistencia del revestimiento. En definitiva, el poliuretano expandido, la perlita expandida y la fibra en hilos cortos, una vez amasados junto al caucho sintético liquido en una masa homogénea fluida, y aplicada la misma, forman un revestimiento continuo que además de sus propiedades aislantes térmicas, acústicas e impermeables, aporta una gran resistencia a las inclemencias climatológicas, por su resistencia tanto a altas como bajas temperaturas, incluso a las potentes granizadas por su efecto rebote, gracias a su gran flexibilidad y absorción a los impactos, evitando roturas de los materiales expuestos a dichas inclemencias, o por circunstancias imprevisibles, asi como a conseguir efectos decorativos, sin necesidad de aplicar ningún otro material . Finally, it is also important the small proportion of white fiber in the form of short strands added, whose main function is to act as reinforcement material, since during the curing process they constitute a three-dimensional and homogeneous reinforcement throughout the mass of material, providing a greater resistance to mechanical stresses of bending, traction or cutting, thus improving the resistance of the coating. In short, the expanded polyurethane, the expanded perlite and the fiber in short threads, once kneaded together with the liquid synthetic rubber in a fluid homogeneous mass, and applied the same, form a continuous coating that in addition to its thermal, acoustic and thermal insulating properties waterproof, it provides a great resistance to the inclement weather, for its resistance to both high and low temperatures, even to the powerful hailstones for its rebound effect, thanks to its great flexibility and absorption to impacts, avoiding breakage of the materials exposed to said inclement weather, or due to unforeseeable circumstances, as well as to achieve decorative effects, without the need to apply any other material.
Este revestimiento presenta unas excelentes propiedades de aislamiento continuo, aislante térmico, acústico, elástico e impermeable, y todo ello en un solo producto. Es barato, ecológico y de fácil aplicación en suelos, fachadas y cubiertas, incluso muy ligeros, por lo que no afecta a las estructuras que soportan las cargas. Además es muy resistente y duradero por afectarle mínimamente el cambio constante de temperaturas, sufriendo dilataciones y contracciones muy leves, por lo que sufre un desgaste mínimo. This coating has excellent properties of continuous insulation, thermal insulation, acoustic, elastic and waterproof, and all this in a single product. It is cheap, ecological and easy to apply on floors, facades and roofs, even very light, so it does not affect the structures that support the loads. It is also very resistant and durable because it minimally affects the constant change of temperatures, suffering very slight dilations and contractions, so it suffers minimal wear.
