    摘要： A method of preparing transparent or nontransparent silica aerogel granules. The method includes forming a granular wet gel by spraying a silica sol into alcohol, the silica sol being prepared by mixing a water glass solution or an opacifier-containing water glass solution with an inorganic acid solution, forming a granular alcohol gel through gelation aging and solvent substitution of the granular wet gel in alcohol, hydrophobically modifying the surface of the granular alcohol gel using an organic silane compound, and drying the surface modified gel at ambient pressure or in a vacuum. The method may prepare silica aerogel granules in a short period of time through heat treatment at a relatively low temperature and at ambient pressure or in a vacuum, thereby ensuring excellent economic feasibility, continuity and reliability, suited for mass production.

    摘要： Disclosed herein is a rapid preparation process of aerogel. More specifically, the present invention relates to a rapid preparation process of aerogel which enables a considerable reduction in preparation time and preparation costs via simultaneous treatment of solvent exchange and surface-modification of hydrophilic-to-hydrophobic transition.The rapid preparation process comprises mixing a cation exchange resin with sodium silicate (water glass) as a starting material, and removing the sodium ion from the sodium silicate, to subject the sodium silicate to ion exchange; adding a base catalyst and an organosilane compound to the sodium silicate to subject the sodium silicate to gelation; aging the gellized silica gel at room temperature for 2 to 4 hours to discharge water from the silica gel and to modify the surface of the silica gel into hydrophobicity; and drying the hydrophobic silica gel at atmospheric pressure for 18 to 27 hours.
