MÉTODO DE OBTENCIÓN DE UNA MASA DE REFUERZO PARA PLACAS DE MARMOL Y PLACAS ASÍ OBTENIDAS METHOD OF OBTAINING A MASS OF REINFORCEMENT FOR MARBLE PLATES AND PLATES SO OBTAINED

DESCRIPCIÓNDESCRIPTION

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION

La presente invención consiste en un método de obtención de una masa de refuerzo para placas de mármol comprendiendo igualmente las placas de mármol obtenidas haciendo uso de tal refuerzo.The present invention consists in a method of obtaining a reinforcement mass for marble plates, also comprising the marble plates obtained using such reinforcement.

El método de obtención de la masa de refuerzo consiste principalmente en una mezcla de un ligante hidráulico, un aporte de carga inerte, y al menos un aditivo elastomérico.The method of obtaining the reinforcement mass consists mainly of a mixture of a hydraulic binder, an inert filler, and at least one elastomeric additive.

La masa resultante muestra un tiempo de curación muy reducido frente a las masas de refuerzo empleadas habitualmente a base de cemento o yesos. Este tiempo de curación mucho más reducido redunda en tiempos de espera mucho más reducidos hasta la manipulación.The resulting mass shows a very short healing time against the reinforcement masses usually used based on cement or plasters. This much shorter cure time results in much shorter wait times until handling.

Se hace uso de esta masa de refuerzo para la ob- tención de placas de mármol por división consecutiva y refuerzo en la cara exterior permitiendo las caracterís¬ ticas mecánicas de la masa obtener placas de mármol de espesores muy reducidos.This mass use of reinforcing is for obtention of marble slabs consecutive division and reinforcement on the outside allowing the characteris tics of the mechanical ¬ obtain mass marble plates of very low thickness.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Son conocidas las prácticas de reforzar placas de mármol de espesor reducido mediante masas de mortero o mediante resinas epóxicas para manipular placas que de otra manera requerirían grosores mayores. Como ejemplo, la patente de invención con número de publicación español ES2172394 describe un procedi¬ miento de fabricación de placas de mármol para la cons¬ trucción que se obtienen a partir de los bloques de mármol extraídos de las canteras, sobre cuyas placas se fijan mediante resina de poliéster sendas planchas de poliuretano, efectuándose luego un corte de división por la mitad del grosor de la placa, con lo que resultan dos piezas de reducido grosor.The practices of reinforcing marble plates of reduced thickness by mortar masses or by epoxy resins for handling plates that would otherwise require larger thicknesses are known. For example, the patent with number Spanish publication ES2172394 describes a proce ¬ ment manufacturing marble slabs for cons ¬ struction obtained from marble blocks extracted from quarries, on which plates are fixed by polyester resin two polyurethane sheets, then making a split cut in half the thickness of the plate, resulting in two pieces of reduced thickness.

En la presenta invención se hace uso de materia¬ les muy baratos, con capacidad de reutilización del polvo de corte de mármol y con tiempos de fraguado del orden de minutos para una rápida manipulación o segunda obtención de placas a partir de las anteriores.In the present invention using matter becomes ¬ them very cheap, with reusability of dust marble cutting and setting times of the order of minutes for quick handling or second plate - making from the above.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

La presente invención consiste en un método de obtención de una masa de refuerzo para placas de mármol consistente en una mezcla que es capaz de fraguar en tiempos muy reducidos y predecibles en función de los porcentajes empleados.The present invention consists of a method of obtaining a reinforcing mass for marble slabs consisting of a mixture that is capable of setting in very short and predictable times depending on the percentages used.

La mezcla emplea un ligante hidráulico obtenido de la calcinación a bajas temperaturas de yeso natural o industrial, seguido de un rápido enfriamiento, como el comercializado como "Gypcement", una carga que princi¬ palmente estará compuesta por el polvo de mármol obteni- do en el corte y que es difícil reciclado, más un aditi¬ vo.The mixture employs a hydraulic binder obtained by calcining at low temperature of natural or industrial gypsum, followed by rapid cooling, such as that marketed as "Gypcement" ¬ a load princi pally be composed of marble powder obtained in cutting and difficult recycling, plus aditi ¬ vo.

El aditivo utilizado en la invención disminuye los requerimientos de agua, aumentando la velocidad de curado. De esta forma la placa de mármol se puede mani¬ pular con rapidez ya que cura antes que con otras masas de refuerzo.The additive used in the invention decreases water requirements, increasing the speed of cure. Thus the marble plaque can manifest ¬ Pular quickly as cure rather than with other bodies of reinforcement.

El aditivo elastomérico utilizado en la presente invención, no se ha utilizado hasta el momento para facilitar el fraguado de masas.The elastomeric additive used in the present invention has not been used so far to facilitate mass setting.

La carga utilizada en la mezcla es polvo de már- mol que se obtienen en el corte de otras placas. Este polvo de mármol es un material inerte que aumenta el volumen de la mezcla y la abarata, ya que de no ser utilizado en la mezcla, el polvo de mármol es un residuo difícil de reciclar.The load used in the mixture is marble powder obtained in the cutting of other plates. This marble powder is an inert material that increases the volume of the mixture and the abarata, since if not used in the mixture, the marble powder is a difficult residue to recycle.

Igualmente se puede utilizar como carga cemento Pórtland, o yeso beta con objeto de modificar el color.Likewise, Portland cement or beta plaster can be used as filler in order to modify the color.

El método de obtención de la masa de refuerzo consiste en llevar a cabo el fraguado de una mezcla compuesta de un ligante hidráulico obtenido de la calci¬ nación a bajas temperaturas de yeso natural o indus¬ trial, seguido de un rápido enfriamiento, como el comer¬ cializado como "Gypcement" en un porcentaje mayor que el 40% y aditivos elatoméricos en un porcentaje menor que el 7%. Igualmente se puede incorporar una carga en un porcentaje menor que el 40%.The method of obtaining the mass of reinforcement consists of carrying out the hardening of a mixture comprising a hydraulic binder obtained calci ¬ nation at low temperatures of gypsum or indus ¬ trial, followed by rapid cooling, such as eating ¬ cialized as "Gypcement" in a percentage greater than 40% and elastomeric additives in a percentage less than 7%. Likewise, a load can be incorporated in a percentage lower than 40%.

La placas de mármol con la masa de refuerzo de la presente invención presentan una cara vista de mármol y una masa de refuerzo posterior, mostrando una mayor resistencia mecánica y en un menor espacio de tiempo.The marble plates with the reinforcement mass of the present invention have a marble face and a posterior reinforcement mass, showing greater mechanical strength and in a shorter space of time.

DESCRIPCIÓN DE LOS DIBUJOS Se complementa la presente memoria descriptiva, con un juego de gráficos, ilustrativos del ejemplo preferente y nunca limitativos de la invención.DESCRIPTION OF THE DRAWINGS The present specification is complemented with a set of graphics, illustrative of the preferred example and never limiting of the invention.

La Figura 1 muestra dos gráficos donde se repre¬ senta una comparación de la resistencia mecánica que presentan en función del tiempo, distintos refuerzos de placas de mármol.Figure 1 shows two graphs where ¬ repre sents is a comparison of mechanical resistance presented according to time, various reinforcements marble slabs.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de lo anteriormente enunciado, la presente invención consiste en un método de refuerzo para placas de mármol y la placas asi obtenidas.In view of the foregoing, the present invention consists of a reinforcement method for marble plates and the plates thus obtained.

La mezcla que presenta unas mejores proporciones mecánicas comprende:The mixture that has better mechanical proportions comprises:

Gypcement 70%-80% Aditivos 2.5%-4% Carga de polvo de mármol 20%-30%Gypcement 70% -80% Additives 2.5% -4% Marble powder load 20% -30%

En la figura 1 se muestran dos gráficos, en am¬ bos se representan, una comparativa en cuanto a resis- tencia mecánica de la masa de refuerzo de la invención, del gypcement, y de cemento Portlan. En el gráfico superior se representa horas frente a megapascales, y en el inferior minutos frente a megapascales.Figure 1 shows two graphs in am ¬ bos are represented, a comparative regarding mechanical strength of the mass of the inventive reinforcer, of the gypcement and cement Portlan shown. In the upper graph, hours versus megapascals are represented, and in the lower one, minutes versus megapascals.

En ambos gráficos se aprecia como la resistencia de la masa de refuerzo de la invención es mayor que la resistencia del Gypcement y del cemento Pórtland, lo que permite que el espesor de la placa de mármol sea menor, alargando la vida de la cantera. En el gráfico inferior se representa minutos frente a Megapascales con objeto de representar que la masa de refuerzo de la invención alcanza niveles de resistencia mecánica más altos en menor espacio de tiempo, asi tras 60 minutos de curado la masa de refuer¬ zo de la invención alcanza una resistencia de 5.5 Mpa frente al Gypcementen que tan solo muestra un valor de 0.5 Mpa y el Cemento Pórtland que se mantiene en cero.In both graphs it can be seen how the strength of the reinforcement mass of the invention is greater than the resistance of the Gypcement and Portland cement, which allows the thickness of the marble plate to be smaller, extending the life of the quarry. In the lower graph minutes is plotted against megapascals in order to represent the mass of reinforcing the invention achieves higher levels of mechanical strength in shorter time, so after 60 minutes of curing mass strengthens Colombian ¬ zo of the invention it reaches a resistance of 5.5 Mpa against the Gypcementen that only shows a value of 0.5 Mpa and the Portland Cement that remains at zero.

Esto es gracias a que la velocidad de curado de la masa de refuerzo de la invención es mucho más rápida, además de realizarse al aire sin necesidad de horno. Por esto las placas de mármol que presentan el refuerzo de la invención se pueden manipular a los 10-30 minutos de haber añadido el refuerzo a la placa, mientras que con otros refuerzo se necesita esperar aproximadamente dos horas si el secado se lleva a cabo en un horno.This is thanks to the fact that the curing speed of the reinforcement mass of the invention is much faster, in addition to being carried out in the air without the need for an oven. This is why marble slabs that present the reinforcement of the invention can be manipulated within 10-30 minutes of adding the reinforcement to the plate, while with other reinforcement it is necessary to wait approximately two hours if drying takes place in an oven.

Do not alter the essential nature of this invention variations in the materials, shape, size and arrangement of the component elements, described in a non limi tative ¬, sufficient to proceed to its reproduction by an expert.
