Patent number: 9528048Abstract: The present invention relates to a method for preparing hierarchically ordered structures of inorganic phosphate particles, homogeneously deposited on the surface of a phyllosilicate, which is characterized in that it comprises the following steps: a) obtaining an acid solution of precursor compounds of an inorganic phosphate; b) preparing a dispersion of particles of a phyllosilicate in aqueous medium and acidifying the phyllosilicate dispersion by adding at least one acid, thereby obtaining an acid dispersion; c) mixing the acid solution obtained in step a) with the dispersion obtained in step b); and d), with stirring, adding a base to the mixture obtained in step c) until the required pH value for precipitating the corresponding inorganic phosphate on the phyllosilicate particles has been achieved, resulting in a hierarchically ordered structure of homogeneously distributed submicrometric or nanometric inorganic phosphate particles supported on the phyllosilicate surface.Type: GrantFiled: May 14, 2012Date of Patent: December 27, 2016Assignee: TOLSA, S.A.Inventors: Antonio Esteban Cubillo, Julio Santaren Rome, Eduardo Aguilar Diez, Antonio Alvarez Berenguer, Elena Palacios Zambrano, Maria Pilar Leret Molto, Jose Francisco Fernández Lozano, Antonio Heliodoro De Aza Moya, Miguel Angel Rodriguez Barbero

Patent number: 9447283Abstract: The present invention relates to a method for producing a compound that comprises a pseudolaminar silicate of natural origin, which is at least one clay of the paligorskite-sepiolite group, characterized in that said method comprises the following steps: defibrillating the microfiber bundles of the at least one clay in water; dispersing the defibrillated clay in an organic or inorganic liquid solvent until a stable gel is formed; adding to the dispersion at least one clay-surface-modifying agent; removing the solvent from the dispersion by means of a solid-liquid separation process and/or drying process; and deagglomerating the final compound until a powdered product is obtained. A further object of the present invention is the compound that can be obtained using said method, as well as the use of the compound as an additive or filler in composite polymeric materials in order to enhance the properties thereof, the composite polymeric material likewise being encompassed within the present invention.Type: GrantFiled: January 30, 2012Date of Patent: September 20, 2016Assignee: TOLSA, S.A.Inventors: Julio Santarén Romé, Eduardo Aguilar Díez, Antonio Esteban Cubillo, Antonio Álvarez Berenguer, Esperanza Benito Cano, Nuria García García, Julio Guzmán Perote, Pilar Tiemblo Magro

Patent number: 8871666Abstract: The invention relates to a method of preparing a rheology product from a pseudomlaminar silicate comprising microfiber bundles. The inventive method comprises the following steps consisting in: grinding the pseudolaminar silicate mineral which is selected from sepiolite mineral, attapulgite mineral and combinations of same, with a pseudolaminar silicate concentration of at least 50%, moisture of less than 40% and a particle size of less than 1 mm; mixing the ground pseudolaminar silicate mineral with an aqueous solution of a dispersing component comprising at least one dispersing agent, in order to obtain a first mixture comprising between 35% and 85% water and between 0.1% and 7% dispersant in relation to the weight of the pseudolaminar silicate mineral; and intensively mixing the first mixture obtained in the second step until the dispersion of the pseudolaminar silicate microfibre bundles in order to obtain the rheology product in a dispersion homogeneously mixed with the dispersant and the water.Type: GrantFiled: June 1, 2006Date of Patent: October 28, 2014Assignee: Tolsa, S.A.Inventors: Julio Santarén Romé, Eduardo Aguilar Díez, Antonio Álvarez Berenguer, Juan José Aragón Martínez

Patent number: 7910511Abstract: The invention relates to a method of preparing metallic nanoparticles and to the materials thus obtained. More specifically, the invention relates to a method of preparing metallic nanoparticles consisting in: selecting a precursor from the salts, hydroxides and oxides of metallic elements that can be reduced at temperatures below the clay silicate network destruction temperature; and depositing said precursor on a support selected from pseudolaminar phyllosilicate clays. According to the invention the method comprises: (i) a deposition step in which the precursor is deposited on the support: (ii) when the precursor is selected from among salts and hydroxides, a thermal decomposition step in a controlled atmosphere, in which the precursor is subjected to a decomposition process and is transformed into an oxide of the metallic element: and (iii) a reduction step in which the oxide of the metallic element is subjected to a reduction process in a controlled atmosphere.Type: GrantFiled: June 17, 2010Date of Patent: March 22, 2011Assignee: Tolsa, S.A.Inventors: Julio Santarén Romé, Francisco Javier Limpo Orozco, Eduardo Aguilar Díez, Antonio Álvarez Berenguer, José Moya Corral, Carlos Pecharroman Garcia
