Description

Environment-Friendly Pitch Acoustic Panel and Environment-Friendly Pitch Acoustic Panel Construction Method This invention relates to an eco-friendly perforated sound-absorbing panel and a method for constructing an eco-friendly perforated sound-absorbing panel. In particular, it relates to an eco-friendly perforated sound-absorbing panel and a method for constructing an eco-friendly perforated sound-absorbing panel in which a finishing material having circular fine through holes is adhered to one side of a sound-absorbing core board made of a non-combustible material having circular sound-absorbing holes, and a base material impregnated with charcoal powder is adhered to the other side, thereby providing excellent sound absorption, flame retardancy, and high moisture resistance. Generally, architectural structures are provided with a framework using steel or concrete, and walls are installed within the provided framework. The interior and exterior of the walls are finished by plastering or by attaching separate interior and exterior finishing materials. As a prior art for interior and exterior materials, a non-combustible insulation board for construction was proposed in Public Patent Publication No. 10-2005-0090628 (September 14, 2005). The proposed non-combustible insulation board is designed to provide an aluminum foil layer and an aluminum pearl layer on the upper and lower surfaces of a non-combustible insulation layer made of non-woven fabric combined by needle punching with carbon fibers and silica fibers, and to provide moisture and dust protection by attaching an insulation layer to the bottom of the aluminum pearl layer, but there was a problem in that the effect was not properly obtained. Another prior art disclosed in Public Patent Publication No. 10-2017-0059711 (May 31, 2017) proposed a building insulation material and a frame-integrated non-combustible board. The proposed non-combustible board is designed to be finished with improved insulation, non-combustibility, and durability by providing an intermediate layer between the outer layers and an auxiliary core material within the intermediate layer. However, this also had the same problem of not being able to obtain sufficient sound absorption and sound insulation effects during use. In addition, sound-absorbing panels made of PB (Particle Board) or MDF (Medium Density Fiberboard) with perforated sound-absorbing holes have been widely used for the interior walls of gymnasiums, performance halls, and churches; however, these materials had problems such as being expensive, heavy, and vulnerable to moisture.
