NONFLAMMABLE PANEL MANUFACTURING METHOD USING EXPANDABLE CERAMICS AND NONFLAMMABLE PANEL MANUFACTURED BY THIS

摘要

PURPOSE: A method for manufacturing a non-flammable panel using expandable ceramic and the non-flammable panel are provided to improve the thermal insulating characteristic the lightness of constructing materials using eco-friendly materials. CONSTITUTION: A first mixture is obtained by mixing 35 to 40 parts by weight of stone powder and 5 to 20 parts by weight of pottery stone powder, diatomaceous earth powder, and hydroxyl-apatite powder. The stone powder is composed of one or more of vermiculite, pearlite, and pumice. A second mixture is obtained by mixing 5 to 7 parts by weight of an inorganic binder, 3 to 5 parts by weight of vegetable neutralizing agent, and 0.5 to 1 parts by weight of a controlling agent, based on 100 parts by weight of the first mixture. The second mixture is heated to be shaped. The shaped second mixture is arranged on a metal plate on which an adhesive is applied. The second mixture and the metal plate are compressed to obtain a non-flammable panel. The non-flammable panel is dried, and a flame-resistant pain is coated on the non-flammable panel. The coated non-flammable panel is cut.
