La presente invención incorpora un soporte la bentonita, un tipo de arcilla perteneciente a la familia de las esmectitas, que tiene una morfología laminar común a los filosilicatos. Es una sustancia natural, económica, que respeta el medio ambiente y con una reconocida versatilidad en los procesos de la industria donde se emplea. Está muy disponible como materia prima y también se encuentra como producto elaborado y purificado para aplicaciones específicas.The present invention incorporates a support the Bentonite, a type of clay belonging to the family of smectites, which has a laminar morphology common to Philosilicates It is a natural, economical substance that respects the environment and with a recognized versatility in the processes of the industry where it is used. It is very available as a subject premium and is also found as an elaborated and purified product For specific applications.
A modo de ejemplo, la montmorillonita, un tipo de bentonita sódica, muy hidrófílica empleada como aditivo a productos detergentes, está formada por una unidad estructural básica que consiste en dos placas moleculares constituidas de silicatos en configuración tetraédrica que recubren por las dos caras a una placa de aluminato en configuración octaédrica. La estructura final es una disposición de las tres capas a la manera de sandwish (silicato-aluminato-silicato). Estas placas se unen entre sí por fuerzas e interacciones moleculares para formar una unidad llamada lámina. Esta estructura laminar determina las propiedades fisicoquímicas de las arcillas y por ende las interesantes propiedades o usos tecnológicos de estas sustancias. Las láminas están unidas entre sí por cationes sodio y o potasio o por cationes alcalino térreos en arcillas con menos capacidad de absorber agua.As an example, Montmorillonite, a type of sodium bentonite, very hydrophilic used as an additive to detergent products, is formed by a structural unit basic consisting of two molecular plates constituted of silicates in tetrahedral configuration that cover the two faces to an aluminate plate in octahedral configuration. The final structure is an arrangement of the three layers the way from sandwish (silicate-aluminate-silicate). These plates are joined together by forces and molecular interactions to form a unit called foil. This laminar structure determines the physicochemical properties of clays and therefore the interesting properties or technological uses of these substances The sheets are joined together by sodium cations and or potassium or by alkaline earth cations in clays with less ability to absorb water
En presencia de agua las arcillas se hinchan absorbiendo solutos polares y el agua de la disolución. La zonas de absorción es la interlaminar, favoreciendo el proceso los iones monovalentes allí presentes. La absorción puede continuar hasta que las láminas se separen entre sí y formen una suspensión coloidal. La suspensión es de alta estabilidad, funcional en amplios rangos de pH y concentraciones de electrólitos, lo que condiciona una reologia muy útil y atractiva para la industria.In the presence of water the clays swell absorbing polar solutes and dissolving water. The zones of absorption is the interlaminar, favoring the ions process monovalent there present. Absorption can continue until the sheets separate from each other and form a colloidal suspension. The suspension is of high stability, functional in wide ranges of pH and electrolyte concentrations, which determines a Rheology very useful and attractive to the industry.
La suspensión coloidal del sistema laminar de las arcillas, con el deslizamiento molecular de las láminas unas sobre otras le confiere, según el contenido de agua y demás variables, una reologia plástica, seudoplásticas. También son posibles comportamientos viscosos, viscoelasticos y propiedades tixotrópicas. Por otra parte, forman coloides de gran estabilidad, útiles para dispersar solutos sólidos, oleosos y gaseosos, dotando a estos sistemas de una resistencia estructural incluso a bajas viscosidades. Todo esto les hace muy útiles en la formulación de una amplia gama de productos.The colloidal suspension of the laminar system of the clays, with the molecular sliding of the sheets some on others it confers, according to the content of water and others variables, a plastic rheology, pseudoplastics. They are also possible viscoelastic and viscoelastic behaviors and properties thixotropic On the other hand, they form highly stable colloids, useful for dispersing solid, oily and gaseous solutes, providing to these systems of structural resistance even at low viscosities All this makes them very useful in formulating A wide range of products.
Las bentonitas se han descrito como unos potentes agentes suavizadores de los textiles, compatibles con los detergentes aniónicos y que respetan el medio ambiente. Cuentan por ello con grandes ventajas sobre los suavizantes catiónicos basados en el amonio cuaternario.Bentonites have been described as ones powerful fabric softening agents, compatible with anionic detergents that respect the environment. They count for this with great advantages over cationic softeners based in the quaternary ammonium.
La presencia de una gran superficie específica de las arcillas que en las bentonitas del tipo montmorillonita puede oscilar entre 80 a 300 m^{2}/g unida al hecho que estas superficies laminares presentan cierta carga negativa las hace químicamente activas para procesos de adsorción y absorción. Son conocidas las aplicaciones de arcillas como soporte transportador-liberador de sustancias activas como insecticidas, herbicidas, pesticidas y medicamentos. También se ha estudiado y aplicado su utilidad en alimentación animal como soporte transportador de vitaminas, sales minerales y antibióticos al tracto digestivo animal e incluso como adsorbente de toxinas que pudiesen estar presentes en el tracto digestivo de los animales. De modo que las amplias bondades de las bentonitas como adsorbente-absorbente están técnica y científicamente muy avaladas.The presence of a large specific surface of the clays that in the montmorillonite bentonites it can range from 80 to 300 m2 / g together with the fact that you are laminar surfaces have a certain negative charge Chemically active for adsorption and absorption processes. They are known clays applications as support transporter-releasing active substances such as insecticides, herbicides, pesticides and medications. It has also studied and applied its usefulness in animal feed as carrier for vitamins, minerals and antibiotics to the animal digestive tract and even as an adsorbent of toxins that they could be present in the digestive tract of animals. From so that the broad benefits of bentonites as adsorbent-absorbent are technical and scientifically highly endorsed.
Las arcillas naturales presentan afinidad por compuestos polares e hidrofílicos, pero es posible modificarlas químicamente para que presenten afinidad por compuestos orgánicos menos polares. Se han desarrollado bentonitas modificadas con carácter organofilico, de manera que se amplia su capacidad como soporte a prácticamente todas las sustancia químicas.Natural clays have an affinity for polar and hydrophilic compounds, but it is possible to modify them chemically to present affinity for organic compounds less polar Modified bentonites have been developed with organophilic character, so that it expands its capacity as Support to virtually all chemicals.
La presente invención se basa en estas propiedades de superficie que presentan las bentonitas. El repelente de mosquitos actuará adsorbido o absorbido a la arcilla, según el grado de hidratación y agregación que presente la bentonita. La inclusión del complejo bentonita-repelente en formulaciones de detergentes y suavizantes transportará el repelente al tejido, depositándose éste sobre el textil con el consiguiente efecto antimosquitos. El efecto se refuerza por la deposición de la propia bentonita unida al repelente sobre los tejidos. Se añade el efecto suavizante de tejidos y liberador de la sustancia repelente de mosquitos que presenta la bentonita en la invención.The present invention is based on these surface properties that bentonites present. He Mosquito repellent will act adsorbed or absorbed to the clay, according to the degree of hydration and aggregation that the bentonite. The inclusion of the complex Bentonite-repellent in detergent formulations and softeners will transport the repellent to the tissue, depositing this one on the textile with the consequent anti-mosquito effect. He effect is reinforced by the deposition of the united bentonite itself to the repellent on the tissues. The softening effect of tissues and releasing the mosquito repellent substance that presents bentonite in the invention.
