SILICA-BASED NONFLAMMABLE MATERIAL FOR REPLACING ASBESTOS AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a silica-based nonflammable material and to a method for preparing same, and more particularly, 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. According to the present invention, 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 are used as main ingredients, the materials may be used as building materials which are not harmful to the human body and which can replace asbestos that has been widely used as a conventional building material for thermal insulation, soundproofing, etc.
