Their use as polymeric materials for the filler and a method for producing a compound based on pseudo-layered silicate

摘要

The present invention, at least the following steps: a step of de-fibrillation in water a bunch of micro-fibers of clay at least one; dispersed in a liquid solvent of an organic or inorganic until they form a stable gel, clays and de-fibrillated in the dispersion, the process to add a denaturant of clay at least one surface; process to be by dry separation method and / or solid-liquid separation method, a process to remove from the dispersion of the solvent; powder like product and until it is obtained, the process of de-agglomerate the final compound; characterized in that it comprises, sepiolite - relates to a process for preparing compounds containing the pseudolaminar silicate of natural origin is a clay of at least one of the palygorskite group. It is the use of the compounds as additives or fillers in the composite polymer material in order to improve the properties, and the compounds may be obtained by using the above method, a further object of the present invention, the composite polymer material is within the scope of the invention as well.
