    摘要: Stable vermiculite dispersions which are substantially free of settling and a method of preparing same are provided. The dispersion are obtained by treating the vermiculite platelets of which the dispersion is comprised with citrate anion. The citrate anion functions as a swelling agent for the vermiculite and enhances the rate and extent of swelling in an aqueous medium. The swollen vermiculite is delaminated by shearing to provide the inventive dispersions, which comprise a suspension of the delaminated platelets and citrate anion.

    摘要: A cementitious mixture including water-repellent vermiculite, polypropylene fibers and cement. A preferred embodiment utilizes: asphalt-coated, expanded vermiculite; collated, fibrillated polypropylene fibers; and non-shrinking Portland cement. Test data indicates a greatly increased compressive strength compared to previously known vermiculite insulating concretes. A prefabricated building panel utilizing the mixture of the present invention, and a method of manufacture thereof, are also disclosed. Calculated R values indicate good thermal insulating characteristics.

    摘要: This invention is directed to the preparation of an organic-inorganic composite body demonstrating hydrophobic behavior containing crystals of an organic polycation-exchanged lithium and/or sodium water-swelling mica, the organic polycation being selected from the group of aminosilanes and organic chrome complexes. The process of preparing such products contemplates the steps of:(a) forming a glass-ceramic body containing crystals selected from the group of fluorhectorite, hydroxyl hectorite, boron fluorphlogopite, hydroxyl boron phlogopite, and solid solutions among those and between those and other structurally-compatible species selected from the group of talc, fluortalc, polylithionite, fluorpolylithionite, phlogopite, and fluorphlogopite;(b) contacting said body with a polar liquid for a time sufficient to cause swelling and disintegration thereof accompanied with the formation of a gel; and(c) contacting said gel with a source of organic polycations selected from the group of aminosilanes and chrome complexes to cause an ion exchange reaction to occur between said polycations and the Li.sup.+ and/or Na.sup.+ ions from the interlayer of said crystals, whereby essentially all of said Li.sup.+ and/or Na.sup.+ ions are replaced with said organic polycations.Paper, board, film, fiber, and coating can be formed from the exchanged gel, and dried powders thereof can be hot pressed to yield a body consisting of a cross-linked organic polycation-mica derivative.
