Title: Silica-based nonflammable material for replacing asbestos and method for preparing same

Abstract: The present application relates to a silica-based nonflammable material and to a method for preparing same. More particularly, the application relates to a silica-based nonflammable material which contains silica, limestone, and albite as main ingredients, which is obtained by a series of processes including grinding, melting, spraying, and molding, and which can replace asbestos, as well as to a method for preparing same. As functional building materials which are nonflammable even at high temperatures can be prepared using silica-based nonflammable materials consisting of silica-based minerals, and as only natural minerals may be used as main ingredients. The materials used as building materials may not be harmful to the human body and can replace asbestos that has been widely used as a conventional building material for thermal insulation, soundproofing, etc.
