Abstract

La présente invention porte sur un procédé pour la production d'une particule composite, suivant lequel un composé choisi parmi un alcoxysilane, un silane contenant des groupes silanol et un produit de condensation partielle de ceux-ci est ajouté à une solution mélangée obtenue par mélange d'au moins une solution aqueuse dispersée mélangée dans laquelle une poudre inorganique et un élastomère de silicone sont dispersés, d'un polymère cationique hydrosoluble et d'une substance alcaline, une réaction d'hydrolyse-condensation étant effectuée pour produire une particule composite constituée de la poudre inorganique sur la surface de laquelle l'élastomère de silicone a adhéré à l'aide d'une résine de silicone servant de liant. Le procédé permet de produire, indépendamment de la nature de poudres inorganiques, une particule composite dans laquelle un élastomère de silicone a adhéré uniformément sur la surface d'une poudre inorganique.
