COMPOSITE REFRACTORY BUILDING MATERIAL, METHOD OF MANUFACTURING THE SAME, GYPSUM BOARD, AND RESIN COMPOSITION

摘要

Since a refractory composite constructional material is a material in which a reinforcing layer composed of a thermosetting resin and a mineral fiber is provided on at least one side of a porous inorganic core material such as a plasterboard, it is excellent in the refractory properties, the processing properties, the laying properties, the nail endurance force and the strength, is light and low cost. A plurality of plasterboards may be laminated. A covering layer for preventing a plaster powder from flying may be formed on a butt end surface of a refractory composite constructional material. A patterned layer or an electromagnetic wave shielding layer may be provided on a refractory composite constructional material. A resin composition comprising a thermosetting resin and an elastic polymer has the nail endurance force. This resin composition may be impregnated into a porous substrate or a fibrous substrate and cured to make a molded sheet which may be laminated on a core material to make a molded plate. <IMAGE>
