Silanated clay compositions and methods for making and using silanated clay compositions

摘要

Clay compositions useful for modification of organic and aqueous fluids may be prepared from clays, silicon compounds, onium compounds or combinations thereof. An aqueous clay slurry may be acidified to form an acidic clay slurry. At least one silicon compound may be contacted with the aqueous clay slurry to form a silanated clay composition. In certain embodiments, a silanated clay composition may be contacted with an onium ion to form a silanated organoclay composition. In some embodiments, the silanated clay compositions may be incorporated into monomer and/or polymer systems to make composites with improved performance.
