Production of expanded clay from aminoalkyl silanes comprises solvent treatment of natural clay to incorporate aminoalkyl silane enhancing adhesion and thermal stability

NOVELTY – The production of expanded clay from aminoalkyl silanes has chemical treatment in aqueous or organic solvent of natural clay to intercalate aminoalkyl silane between the laminae of the mineral. Also claimed is the product of the process. CLAIMED PRODUCT – The product is expanded and undergoes surface modification by the aminoalkyl silane, with corresponding increase in its thermal stability and adhesion to polymer matrices. USE – In Civil engineering.

Main Application Field

A93 (Roads, building, construction flooring.); L02 (Refractories, ceramics, cement – includes manufacturing methods, limes, soil preparation for (road) building, magnesias and slags, cements, mortars, concretes, abrasives, thermal or acoustic insulation (non)oxide ceramics and ceramic composites, but not brick making, concrete mixers or casting or potters’ wheels (C04).)
