Adhesivo de cal lime adhesive
La presente invención se refiere a un adhesivo de cal y a las aplicaciones dadas al mismo. The present invention relates to a lime adhesive and the applications given thereto.
Antecedentes de la invenciónBackground of the invention
Son conocidos los adhesivos en construcción basado en productos como el cemento, el poliuretano entre otros, que permiten la adherencia para alicatados, pavimentos, baldosas mediante una fijación de las piezas a la superficie. Adhesives in construction based on products such as cement, polyurethane, among others, are known, which allow adhesion for tiling, flooring, and tiles by fixing the pieces to the surface.
Por ejemplo, en la patente española con número de publicación ES346090, se describe un procedimiento para la fabricación de un producto aglutinante y adhesivo para la construcción que se caracteriza porque comprende una mezcla de albuminoide y cloruro sódico, cal, yeso y principalmente cemento. For example, in the Spanish patent with publication number ES346090, a procedure is described for the manufacture of a binder and adhesive product for construction that is characterized in that it comprises a mixture of albuminoid and sodium chloride, lime, gypsum and mainly cement.
En la presente invención se pretende obtener un producto exento de cemento y resinas de hidrocarburos, pero con buenas prestaciones para su uso como adhesivo para construcciones. The present invention aims to obtain a product free of cement and hydrocarbon resins, but with good performance for use as a construction adhesive.
Descripción de la invenciónDescription of the invention
Los adhesivos en construcción posibilitan realizar uniones directas por simple contacto a través de un tercer material, que es el adhesivo. La adherencia es una forma de unión física entre objetos, una fuerza de atracción que mantiene unidas moléculas de diferente naturaleza química. Adhesives in construction make it possible to make direct joints by simple contact through a third material, which is the adhesive. Adhesion is a form of physical union between objects, a force of attraction that keeps molecules of different chemical nature together.
En la presente invención se ha desarrollado un producto adhesivo que se basa en cal aérea en pasta que ha sido envejecida en silos durante al menos seis meses. In the present invention, an adhesive product has been developed that is based on aerial lime paste that has been aged in silos for at least six months.
En la presente descripción se denomina "cal aérea” al producto que resulta de la transformación por el calor de las rocas calizas, entre 900°C y 1000°C, a óxido de cal y este óxido de cal, tras la inmersión en agua se transforma en hidróxido cálcico o cal aérea en pasta. En la presente invención este proceso debe de durar al menos seis meses, lo que se denomina cal aérea de pasta envejecida. In the present description, "air lime" is called the product that results from the transformation by heat of limestone rocks, between 900°C and 1000°C, to lime oxide and this lime oxide, after immersion in water, is transformed into calcium hydroxide or paste air lime. In the present invention this process must last at least six months, which is called aged paste air lime.
La presente invención pretende ser un sustituto de otros productos adhesivos basados en cemento, presentando el producto de la presente invención importantes ventajas como la plasticidad del producto, el endurecimiento lento, la retención de agua, porosidad. La cal aérea envejecida que es el componente principal del adhesivo presenta una excelente trabajabilidad y plasticidad. Durante el envejecimiento varía el tamaño y la forma de las partículas de hidróxido cálcico dispersas. Con el tiempo, se produce la lenta trasformación a cristales de laminares de mucho menor tamaño, con lo que se consigue un aumento de la superficie específica y de la viscosidad. La cal aérea envejecida transmite al producto final flexibilidad, excelente comportamiento en ambientes húmedos o sumergidos y extrema adherencia sobre diferentes soportes. The present invention aims to be a substitute for other cement-based adhesive products, the product of the present invention presenting important advantages such as the plasticity of the product, slow hardening, water retention, porosity. The aged air lime that is the main component of the adhesive has excellent workability and plasticity. During aging, the size and shape of the dispersed calcium hydroxide particles varies. Over time, the slow transformation to much smaller lamellar crystals occurs, thereby achieving an increase in the specific surface area and viscosity. Aged aerial lime gives the final product flexibility, excellent performance in humid or submerged environments and extreme adhesion on different supports.
Por otro lado, las cargas son los materiales inertes micronizados a diferentes mallas On the other hand, the fillers are the inert materials micronized to different meshes.
Por lo tanto, un primer aspecto de la presente invención se refiere a un adhesivo de cal que comprende una cal aérea en pasta que ha sido envejecida al menos seis meses comprendido en un porcentaje en peso respecto al peso total del adhesivo entre el 20% y el 40% y cargas en un porcentaje en peso comprendido entre el 80% y el 60%. Therefore, a first aspect of the present invention refers to a lime adhesive comprising an air lime paste that has been aged for at least six months comprised in a percentage by weight with respect to the total weight of the adhesive between 20% and 40% and loads in a percentage by weight between 80% and 60%.
Las ventajas que aporta este producto son: transpirabilidad de los soportes, absorción de CO<2>, regulación térmica, flexibilidad para absorber los movimientos del soporte, alta adherencia sobre diferentes tipos de soporte, gran resistencia a la degradación tanto en ambientes húmedos como sumergidos, ausencia de formación de sales en los substratos, cambios decorativos en estancias, sin necesidad de obras, versatilidad y poder biocida. The advantages provided by this product are: breathability of the supports, CO <2> absorption, thermal regulation, flexibility to absorb the movements of the support, high adhesion on different types of support, great resistance to degradation in both humid and submerged environments. , absence of salt formation in the substrates, decorative changes in rooms, without the need for works, versatility and biocidal power.
El producto de la invención soluciona los problemas de humedades por capilaridad, la dificultad de unir materiales de distinta naturaleza, la reparación de superficies deterioradas, eliminación de patologías de restauración de elementos de patrimonio histórico, producidas por la utilización de materiales no compatibles con los originales. The product of the invention solves the problems of humidity due to capillarity, the difficulty of joining materials of different nature, the repair of deteriorated surfaces, elimination of restoration pathologies of elements of historical heritage, produced by the use of materials not compatible with the originals. .
El adhesivo de cal de la invención es adecuado para su uso en restauración y rehabilitación de modo ecológico y sostenible de paramentos tanto verticales como horizontales, así como adhesivo para otros usos. The lime adhesive of the invention is suitable for use in the ecological and sustainable restoration and rehabilitation of both vertical and horizontal walls, as well as as an adhesive for other uses.
Por lo tanto, otro aspecto de la invención se refiere al uso del adhesivo de cal de la invención en restauración, rehabilitación y para realizar soleras y/o revestimientos de paredes. Therefore, another aspect of the invention refers to the use of the lime adhesive of the invention in restoration, rehabilitation and to make screeds and/or wall coverings.
