Abstract

The invention relates to a combination of two materials, one of which is a rigid material known as EPDM (rubber) and the other being a moulded, vulcanized hydrophilic resin, forming a single body or single profile adapted to all necessary types of geometries, used in metal joinery profiles, wood or other materials which can be used to manufacture said piece of joinery. The properties of said joint are characterized in that the EPDM area provides a rigid support exhibiting a specific degree of elasticity in order to screw or insert the desired profile or area and in that the hydrophilic resin interacts dynamically since the properties thereof result in expansion when chemical reaction occurs with a fluid over a specific time period and according to a desired proportion depending upon the exposure thereof to a degree of humidity or immersion. The inventive system guarantees perfect tightness of the element or set of elements to which it is applied. Tests carried out have revealed that expansion can amount to 8 times the value of the volume thereof and that sealing pressure can amount to 600 kg/cm2, the parameters thereof being conditioned according to the fluid to which the joint was exposed and the amount of freedom determined for the expansion thereof.

Actualmente existe en el mercado diversos compuestos para realizar juntas de estanqueidad en elementos constructivos como las juntas de EPDM , Caucho , silicona , etc.. , materiales los cuales realizan la función de estanqueidad de diversos elementos constructivos que están en contacto directo o indirecto con fluidos. Dichas juntas suelen estar adaptadas a la ubicación de las mismas teniendo unos parámetros de elasticidad mínimos . Currently there are various compounds on the market to make seals in construction elements such as EPDM, Rubber, silicone, etc., materials which perform the function of sealing various construction elements that are in direct or indirect contact with fluids. . These joints are usually adapted to their location having minimum elasticity parameters.
4.-EXPLICACIÓN DE LA INVENCIÓN.4.-EXPLANATION OF THE INVENTION.
Se trata de la unión de dos materiales uno rígido denominado EPDM (caucho) y una resina Hidrofilica moldeada y vulcanizada , formando un solo cuerpo o perfil único adaptándose a las necesidades geométricas que se precisen , para su aplicación en perfiles de carpintería metálica ,de madera u otro material en el que se pudiese fabricar dicha carpintería .It is the union of two rigid materials called EPDM (rubber) and a molded and vulcanized Hydrophilic resin, forming a single body or unique profile adapting to the geometric needs that are required, for application in metal, woodwork profiles or other material in which such carpentry could be manufactured.
Las propiedades de dicha junta son ,que la zona del EPDM nos da un soporte rígido con un determinado grado elasticidad para poder atornillar o embutir en el perfil o superficie deseada , y la resina Hidrofilica es la que interactúa dinámicamente , puesto que las propiedades de la misma son la de expansionarse al reaccionar químicamente con un fluido en tiempo y proporción deseados dependiendo de la exposición de la misma al grado de humedad o inmersión que se exponga. Dicho sistema nos garantizara la estanqueidad perfecta en el elemento o conjunto de elementos donde se aplique.The properties of said joint are that the EPDM area gives us a rigid support with a certain degree of elasticity to be able to screw or embed in the desired profile or surface, and the Hydrophilic resin is the one that interacts dynamically, since the properties of the they are to expand by chemically reacting with a fluid in desired time and proportion depending on the exposure of the same to the degree of humidity or immersion that is exposed. This system will guarantee the perfect tightness in the element or set of elements where it is applied.
Se ha determinado que la expansión puede llegar a ser de 8 veces su volumen y de 600 kg/cm2 de presión de sellado según ensayos realizados, estando condicionados los parámetros al fluido al que este sometida la junta y la distancia de desahogo que se determine para su expansión.It has been determined that the expansion can be 8 times its volume and 600 kg / cm2 of sealing pressure according to tests performed, the parameters being conditioned to the fluid to which the joint is subjected and the relief distance determined to its expansion
