Abstract:
Disclosed is an incombustible composition, an incombustible construction product using the incombustible composition, and a method of producing the incombustible construction product. The incombustible composition includes organic or inorganic fiber, fly ash or bottom ash, fire proofing agent, and curing fire-retardant resin. Additionally, the method includes mixing components, constituting the incombustible composition, with each other, and pressing the incombustible composition using a high pressure hot press, a roller press or an autoclave to give a predetermined shape to the incombustible composition. Therefore, the incombustible composition is advantageous in that it is environmentally- friendly because it contains waste materials, and that it has excellent hardness, strength, and water resistance. Other advantages are that its production costs are relatively low, and that it has excellent incombustibility, depending on the contents of the components constituting the incombustible composition.
Abstract:
Disclosed is an incombustible composition for an access floor board, a method of producing the access floor board using the incombustible composition, and the incombustible access floor board using the incombustible composition. The incombustible composition includes 1 to 90 wt% of stone powder, 1 to 30 wt% of curing fire-retardant resin, 1 to 80 wt% of organic or inorganic fiber, and 1 to 80 wt% of fly ash or bottom ash. Therefore, the incombustible composition is advantageous in that it is environmentally-friendly because it contains waste materials, and that it has excellent hardness, strength, and water resistance. Other advantages are that its production costs are relatively low, and that it has excellent incombustibility, depending on contents of the components constituting the incombustible composition.

Abstract:
Provided are a light-emitting keypad and a method of fabricating the light-emitting keypad. The light-emitting keypad includes: a light guide film; a reflective layer formed on a rear surface of the light guide film; a first adhesive layer formed on a rear surface of the reflective layer; and a substrate located under the first adhesive layer and having a dome, wherein the first adhesive layer is located in a region corresponding to the dome. Another light-emitting keypad includes: a light guide film; a first adhesive layer and a reflective layer that are formed on a rear surface of the light guide film; and a substrate located under the first adhesive layer and the reflective layer and having a dome, wherein the first adhesive layer is located in a region corresponding to the dome, and the reflective layer is located in a region other then the region corresponding to the dome. Thus, the dome can be fixed without use of a separate sheet for fixing the dome, resulting in a thinner light-emitting keypad.
