Patent

CA 2635373

The invention relates to a method for producing intercalated nanocomposites from organic materials with laminar structures. The inventive method is characterised in that it comprises the following steps consisting in: reducing the size of the laminar particles and purifying same, pre-treating the natural and/or synthetic structures using precursors, intercalating modifiers into the laminar structure, adding the product resulting from the previous step in liquid form during the processing of a plastic matrix and/or precipitating the product resulting from the previous step in order to obtain a masterbatch, and incorporating the masterbatch into a plastic matrix using any plastic processing means.

L'invention concerne un procédé de fabrication de nanocomposites intercalaires de matériaux organiques ayant des structures laminaires. Ledit procédé consiste à réduire la dimension des particules laminaires et à les purifier ; à prétraiter les structures laminaires naturelles et/ou synthétiques au moyen de précurseurs ; à intercaler des modificateurs dans la structure laminaire ; à ajouter le produit obtenu à l'étape précédente sous forme liquide pendant le traitement d'un liant plastique et/ou à précipiter le produit obtenu à l'étape précédente pour obtenir un mélange maître, puis à incorporer le mélange maître dans un liant plastique au moyen d'un quelconque moyen de traitement des plastiques.
