    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.
